Introduction: Rheumatoid arthritis is an inflammatory chronic, disease. Rheumatoid arthritis leads to swelling, stiffness, pain, and probable loss of function in numerous joints, including the TMJ. Patients on steroid medications usually suffer from: ease of infection osteoporosis and also they have a risk of the gingival inflammation at the implant sites if the patient is unable to maintain the oral hygiene measurements to control the plaque following the treatment. Due to these problems the Dentists hesitate to perform dental implant for them. Aim of the study: To evaluate the effect on the TMJ and the bone density in patients with RA and under treatment for a long time. Material and methods: 72 patients were divided into 3 groups: group A: 24 normal patients, group B: 24 patients with rheumatoid arthritis recently discovered, group C: 24 patients with rheumatoid arthritis for at least 10 years and are on a regular treatment and follow up. The angle of the mandible was measured to determine the effect on the TMJ, and some areas were selected to measure the bone density. Results: The results for the angle measurement showed a significant difference between the measured angle in the 3 groups. The biggest angles mean was group A (the control group), while the lowest mean was group C. Regarding the measured density in the 3 groups the highest density was measured in group A, while the least was measured in group C. Conclusion: There is a high correlation between the duration of the RA and the bone density and also an effect on the TMJ which affect the mandibular angle and convert the patient occlusion into skeletal class II despite receiving a treatment.

The present research was conducted to explore the infra bony pockets in chronic and generalized aggressive periodontitis from the radiographic point of view using CBCT. A total of 150 infrabony pockets were included in the study obtained from 33 patients (20 females and 13 males). The defects were classified into 2 equal groups, 75 defects in chronic periodontitis (Group I), 75 in the generalized aggressive periodontitis (Group II). The Simplant program was used to measure the infrabony pocket depth, the vertical bone loss, the defect angulation, the bone density at the base of the defect, the defect volume. Also the percentage of furcation involvement and presence of calculus were recorded. Results showed higher rates of alveolar bone loss, wider defect angles, decreased bone density apical to the defects, larger defect volumes and more furcation involvement in Group II compared to Group I with statistically significant differences. On the other hand Group I showed significant percentage of calculus formation when compared to Group II. So it can be concluded that the multifactorial risk factors associated with generalized aggressive periodontics resulted in too much higher rates of periodontal destruction when compared to the chronic periodontitis group. Also the local factors play an important role in the pathogenesis of chronic periodontitis, but they are of little importance in generalized aggressive forms. The Simplant software technologies enabled measuring the defect volume which can aid in the estimation of the proper graft volume before surgery.

This study was aimed to assess the effect of low intensity laser (LIL) combined with supplementary micronutrients on the healing phase following endosteal dental implant insertion. Thirty implants were installed in the maxillary premolar regions of thirty male subjects of age ranged from 40-45 years old. Subjects were then randomly divided into three groups (I, II, and III), conventional, drug supplementation, and, laser groups. Following implant insertion, the healing phase of group (I) was left to progress spontaneously without any interference. Group (II) was given drug supplementation regimen for two months (one month before and one month after the implant surgery), while the implant insertion in laser group (III) was followed by low intensity (gallium arsenide diode) laser application with wavelength of 904 nm, an output power of 30 mWatts, and a frequency of 9999 Hz for 3 minutes in three sessions on three alternative days starting from the tenth post-operative day. A six month follow up period was applied radiographically to all subjects of both groups using sequential conventional radiographs. Radiographs were digitized by a professional scanner and bone density was recorded. The results revealed that drug therapy reduced the recommended healing time by 8% while laser therapy reduced the recommended healing time by 33%.

The aim of this study was to compare and contrast the influence of low-level laser therapy (LLLT) on the osseointegration of delayed and delayed-immediate dental implants. Forty implants were installed in the maxillary premolar regions of forty male subjects of age ranged 40-45 years old. Subjects were then randomly divided into four groups (I, II, III, and IV), delayed implant control group, delayed implant laser group, delayed-immediate implant control group, and delayed-immediate implant control group. Following implant insertion, the healing phase of groups (I and III) was left to progress spontaneously. Groups (II and IV) were subjected to low intensity (gallium arsenide diode) laser application with wavelength of 904 nm, an output power of 30 mWatts, and a frequency of 9999 Hz for 3 minutes in three sessions on three alternative days starting from the tenth post-operative day. A six month follow up period was applied radiographically to all subjects of both groups using sequential conventional radiographs. Radiographs were digitized by a professional scanner and bone density was recorded. The results revealed that low intensity laser therapy (LLLT) provided an easy as well as efficient method for accelerating bone healing and improving osseointegration whatever the technique used for implant insertion. The study concluded that laser could be used as additional aid for improving osseointgration and increasing the success rate for implantation protocols.<br />Keywords: Laser, LLLT, Osseointegration, Dental Implant.

Aim: This study was carried to evaluate the effect of the placement of PRF membrane beneath the free gingival graft in gingival augmentation surgeries regarding the changes by time in graft horizontal dimension, vertical dimension and total surface area.<br />Subjects and Methods: Sixteen patients were selected. All the patients showed gingival recession with insufficient attached gingiva. The gingival augmentation surgery was decided to be performed as a primary surgery to increase the attached gingiva with no attempt to cover the recession during this study. Group 1 (test group) included eight patients where the gingival augmentation was performed using a free gingival graft in combination with a platelet rich fibrin membrane placed beneath the graft at the recipient site. Group 2 (control group) included eight patients where the gingival augmentation was performed using a free gingival graft only. The graft vertical dimension (GVD) and the graft horizontal dimension (GHD) were measured using William’s graduated periodontal probe. Plaque index, gingival bleeding index and probing depth were used to monitor the oral hygiene status and gingival health condition throughout the study. All the measures were obtained at 2 occasions; the day of the surgery and 1.5 months after the surgery.<br />Results: Regarding the changes in GVD, a statistically significant greater mean and median percent decrease was noted in group 2 after 1.5 month. The same was obtained with the changes in GHD and graft surface area.<br />Conclusion: Using platelet-rich fibrin beneath free gingival graft in gingival augmentation surgery resulted in successful increase in the attached gingiva with less dimensional changes by time in the transplanted free gingival graft compared to using free gingival graft alone.

Background: Among the most common oral cancers is oral squamous cell carcinoma which has high rates of mortality. 5-flurouracil (5-FU) is a widely used chemotherapeutic agent for treatment of head and neck cancers. However, its use has many limitations due to its well- known side effects. Thus, in the current study we aimed to investigate the chemosensitivity of squamous cell carcinoma cells to 5-FU and/or mesenchymal stem cells-derived microvesicles via H&E histopathological examination, in addition to detection of vascular endothelial growth factor (VEGF) and cyclin D1 (CD1) genes’ expression through quantitative RT-PCR analysis. <br />Material & Methods: Human squamous cell carcinoma cell line (SCC152) was treated by 5-FU or Microvesicles or their combination for 24 and 48 hours. Histopathological examination through H&E stain as well as quantitative RT-PCR analysis, for gene expression of VEGF and CD1, were performed. Finally, statistical analysis of the obtained data and correlation between VEGF and CD1 genes’ expression among different groups were performed. <br />Results: Regarding the histopathological results, the combination group, as compared to 5-FU or microvesicles treated groups, showed the most obvious improvement where numerous apoptotic bodies were observed at 24hrs, being markedly increased at 48hrs of culture, while viable cells were rarely seen. Concerning the qRT-PCR results, the combination group showed significant decrease in genes’ expression of both VEGF and CD1 than the 5-FU or microvesicles treated groups. Furthermore, correlation between VEGF and CD1 genes’ expression revealed a very good positive correlation.<br />Conclusions: it was concluded that the combined use of microvesicles and 5-FU resulted in enhanced chemosensitivity of squamous cell carcinoma cells more than the use of either 5-FU or microvesicle alone. In addition, down regulation of VEGF gene expression was associated with decreased CD1 gene expression.

Introduction: Menopause is defined as the cessation of menstruation, which is usually common in life’s fifth decade in most women. The post-menopausal women usually complain of multifarious oral manifestation that develop overtime. Impact of hormonal replacement therapy not only alleviate the side effects but also enhance the oral wellbeing. However, this needs further research to be more justifiable.<br />Aim of study: 1) to investigate degenerative changes in the tongue epithelium of ovariectomized albino rats and 2) to study the effects of hormonal replacement therapy in attenuation of epithelial cell degeneration.<br />Materials & methods: Thirty adult albino female rats were divided into three equal groups: Group I: Control group, Group II: Rats were injected for 75 days with daily dose of 160μg of triptorelin intraperitoneally, Group III: Rats were injected for 75 days with daily dose of 160μg of triptorelin intraperitoneally followed by hormonal replacement therapy of estrogen for 14 days. By the end of the experimental periods all animals were sacrificed and the tongue of all rats were dissected and processed for light and immunohistochemical examinations. <br />Results: Examination of dorsal surface of rat’s tongues in control group revealed normal epithelium with normal taste buds & connective tissue but the epithelium, taste buds cells and connective tissue in-group II were found to be destructed, group III revealed regeneration of focal areas of destruction that was seen in-group II. Immunohistochemical examination of PCNA expression of control group showed moderate PCNA expression, while group II showed weak PCNA expression, group III showed high PCNA expression.<br />Conclusion: Hormonal replacement therapy can relieve the oral signs and symptoms and improve the oral well-being in menopausal women.

To-date, emerging bacterial resistance to the commonly prescribed antibiotics in the management of periodontitis has become a challenging problem making scientists continually seek for new agents. In the present study, propolis (PRO) (natural bee glue) and moxifloxacin (MXF) (new quinolone antibiotic) were evaluated in the treatment of severe generalized periodontitis (gP) as adjuncts to scaling and root planing (SRP). Fifty four subjects with severe gP were randomly assigned into three groups (3 subjects did not complete the study after participation). Group I in which SRP alone was performed to gP patients (SRP group; n=17); group II in which SRP was done to gP patients combined with orally administered propolis 400 mg once daily for 7 days (PRO group; n=16); and group III in which SRP was performed to gP patients combined with oral moxifloxacin 400 mg once daily for 7 days (MXF group; n=18). Pocket depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), plaque (PI) and gingival (GI) indices were recorded at baseline, after 6 and 12 weeks of SRP. Salivary interleukin-1 beta (IL-1β) was evaluated at the same time points for all groups. All three procedures led to significant reductions in PD, CAL, BOP, PI and GI after 6 and 12 weeks. PD reduction and CAL gain were significantly greater in the PRO and MXF groups compared to SRP group at 6 and 12 weeks after therapy (p < 0.01). Importantly, there was no significant variation between PRO group and MXF group after treatment (p > 0.05). Likewise, in PRO and MXF groups, the salivary inflammatory marker (IL-1β) was significantly reduced in comparison to SRP group (p < 0.01). In all groups, salivary IL-1β levels were decreased at 6 and 12 weeks compared to baseline values. It was concluded that the adjunctive use of PRO and MXF to SRP had significantly improved the treatment outcomes in subjects with severe gP comparable to SRP alone. Thus, PRO and MXF showed promising results in the treatment of periodontal disease. <br />KEYWORDS Propolis, Moxifloxacin, Adjunctive treatment, Periodontitis.

Objectives: Combining the anti - tumor effect of thymoquinone (TQ) with the efficient penetration of gold nanoparticles (GNPs) into cells and nuclei as an attempt to treat the induced oral squamous cell carcinoma in buccal pouch of hamster. <br />Materials and methods: This study was carried out on forty two male Syrian golden hamsters (n=42), its age ranged from 6 to 7 weeks, weighting 90-110 gm. Animals were housed with controlled temperature and were given pellets formed of seeds, grain, cracked corn and tap water ad libitum. The hamsters were divided into: Group A: (Control groups) n=24, Group A1: eighteen animals (n=18) were served as “negative control” . Sub-group A1a: Six animals were sacrificed at day zero. Sub-group A1b: Six animals were sacrificed at 14th week. Sub-group A1c: Six animals were sacrificed at 20th week. Group A2: Six animals (n=6) were considered as “positive control”. DMBA was painted to the left cheek pouches, three times /week for 14weeks. Group B: Eighteen animals (n=18) were painted with DMBA to left cheek pouches three times/week for 14weeks, and subdivided into: Sub-group B1: Six animals were injected intra-peritoneal with GNPs/3 times/week for six weeks. Sub-group B2: Six animals were injected intra-peritoneal with TQ/3 times/week for six weeks.Sub-group B3: Six animals were injected intra-peritoneal with GNPs-TQ/3 times/ week for six weeks. All pouches were extracted and prepared to examined through histological examination for any structural changes and immunohistological detection of COX2. <br />Results: Improve superior anti-inflammatory role of TQ when loaded with GNPS in COX-2 retardation and tumor size regression. <br />Conclusion: Thymoquinon loaded on nanogold particle showed protective role in the oral cancer.

Objectives: To evaluate the dimensions and morphology of the alveolar bone in the maxillary central, lateral and canine regions and to correlate these findings with the age and gender of each subject to provide detailed information for immediate implant planning.<br />Subjects & methods: 112 CBCT scans of both genders with non-extracted maxillary right central, lateral and canine were obtained from the database of the Oral and Maxillofacial Radiology Department, Faculty of Dentistry, Cairo University. For each of the three right maxillary anterior teeth bone height was measured from the crest of the ridge till the nasal floor. The bone width was measured at three levels, namely the cervical, the middle and the apical level. The presence and depth of buccal undercuts was also assessed at the three locations. Additionally, the cross-sectional morphology of the alveolar ridge was determined and classified into three different types.<br />Results: The results of this study showed that the bone height at the right central incisor had the least values; meanwhile the canine had the greatest values. Regarding the bone width, the region of the lateral incisor had the thinnest alveolar ridge at the three levels. In all the three locations however, the alveolar width was greater apically than cervically. Besides, the lateral incisor region showed the highest prevalence for presence of buccal undercuts. The greatest depth of buccal undercut however was found in the canine region, meanwhile the smallest depth was found in the central incisor region. For the cross-sectional morphology, Type I (bell-shape) was the most common in all three locations while Type III (hourglass-shape) was the least common. Age did not affect any of the examined parameters. Males showed more height and width of the alveolar bone, while females showed higher prevalence and greater depth of buccal undercuts in all three locations. Males also showed a greater prevalence of Type I (bell-shape) cross-sectional alveolar bone shape, meanwhile females showed a greater prevalence of Type II (trapezoid-shape) and <br />Type III (hourglass-shape).

Background: the aim of this study was to evaluate and compare the effectiveness of root coverage with coronally advanced flap combined with Platelet Rich Fibrin or Fresh Amniotic Membrane. <br />Materials and Methods: thirty patients had Miller class I or II in maxillary anterior teeth were involved in the present study. Each recession defect was randomly assigned to one of the treating groups: coronally advanced flap with Platelet rich fibrin (PRF group) and coronally advanced flap with fresh amniotic membrane (AM) (AM Group). Clinical measurements of recession depth (RD), root coverage percentage (RC%) pocket depth (PD), clinical attachment level (CAL) and width of keratinized tissue (WKT) were evaluated at the baseline, three months, six months and nine months postoperatively. Statistical analysis was performed for intergroup and intragroup comparisons respectively. <br />Results: intragroup comparison displayed statistical significant difference with regard to RD and CAL at different time interval. No statistical significant difference between groups at different time interval with regard to RD, PD, CAL while WKT, AM group demonstrated statistical significant increase compared to PRF group. <br />Conclusion: Both the membranes provided successful and predictable root coverage when combined with CAF. AM was more effective in terms of increase in WKT.

Background and aim: In normal stratified squamous epithelia, syndecan-1 works as cell adhesion molecule, and exhibits an important role in the regulation of cell growth and differentiation during the development. It is recognized as tumor marker with diagnostic and prognostic role in different cancer types. This study was planned to explore the role of syndecan-1 in oral squamous cell carcinoma.<br />Materials and Methods: Twenty two cases were histologically diagnosed as Oral Squamous Cell Carcinoma (OSCC) that simultaneously contained dysplastic epithelium and carcinoma in situ (CIS) foci. Immunohistochemical staining for syndecan‑1, alpha smooth muscle actin and Ki-67 were done.<br />Results: Decreased expression of syndecan-1 from normal epithelia to CIS. In OSCC parenchyma, transition from cell membrane localization into cytoplasm was detected. In addition, strong expression of syndecan-1 in stromal fibroblasts was observed.<br />Conclusion: Decreased expression of syndecan-1 in parenchymal cells together with its appearance in stromal fibroblasts might be used as a reliable tool in oral squamous cell carcinoma early diagnosis.

Background: Cisplatin is one of mostly used chemotherapeutic drugs. Eventhough, cisplatin drawbacks limit its use. Acetyl L- Carnitine is a neuro-protective and anti-oxidant agents as well as it has anti-apoptotic properties.<br />Aim of the study: this study was designed to evaluate the mechanism of Cisplatin to influence tissue in the pathway of apoptosis or the pathway of necrosis and the protective role of Acetyl-L-Carnitine against cytotoxicity induced by Cisplatin in the dental pulp. <br />Material and methods: Total of 30 male albino rats (250-300 grams) were divided equally into three groups where saline was given to the control group (Group I), Cisplatin was injected into group II the (Cisplatin Group), and L- Carnitine was given to the Group III (L- Carnitine group + Cisplatin) before the injection of Cisplatin. After sacrificing the rats one week later, the extraction and preparation of their jaws were carried out in order to examine their dental pulp histologically histologically and immunohistochemically. <br />Results: The light microscopic results showed degeneration in the dental pulp tissue of group II animals represented by cytoplasmic vacuolization, idiopathic calcification, hyaline and fatty degeneration. While group III showed normal dental pulp tissues with dilated blood vessels. Immunohistochemical examination showed significant differences in group II when compared to control group for both Bax (p=0.0002) and TNF-α (p=0.0029). No significant differences appeared in group III when compared to control group for both Bax and TNF-α. Significant differences were evident in comparison between group II and group III for both Bax (p=0.0015) and TNF-α (p=0.000001).<br />Conclusion: Cisplatin has a devastating effect on dental pulp tissues via both the apoptosis and necrosis pathways. L-Carnitine had a protective effect against the cytotoxicity of Cisplatin.

Background : Vitamin D deficiency is a common health problem worldwide and linked to some infectious and inflammatory conditions, including periodontal disease. This is a double blind randomized controlled study to evaluate the clinical effectiveness of Vitamin D supplementation as an adjunct therapy to non-surgical periodontal treatment in healthy middle-aged vitamin D deficient patients with chronic periodontitis. <br />Material and Methods: Twenty eight patients with mild to moderate chronic periodontitis were included in this study . They were randomized to two groups: Test Group taking oral Vitamin D supplementation 10,000 IU one tablet daily for five days per week for a total duration of 12 weeks and Control Group taking placebo pills. Both groups were maintained on scaling and root planning sessions. Data was collected at baseline and at three months including the following clinical periodontal parameters: Gingival index (GI), Plaque index (PI), Probing pocket depth (PPD) and Clinical attachment level (CAL). <br />Results: Intra-group analysis showed that both groups had significant improvements in the periodontal measures. However, analysis comparing changes in the mean periodontal indices between groups showed that the mean changes across all periodontal indices between groups were statistically significant at pConclusion: Adjunctive low cost Vitamin D supplementation in mild to moderate chronic periodontitis in middle aged Vitamin D deficient healthy patients significantly improves clinical periodontal outcomes relative to scaling and root planning alone with no side effects. Vitamin D is safe and probably may contribute to decrease health care costs as an adjunctive therapy to conventional periodontal treatment.

Background: Primary teeth are excellent model to figure out the differences in morphological and histological features of tooth resorption. They may be exfoliated due to physiological resorption of their roots or the coexistent physiological and pathological resorption that are usually observed in the replacement period of dentition. <br />Aim: The aim of this study was to evaluate the qualitative differences in the appearance of the roots of primary teeth undergoing physiological or coexistent physiological and pathological root resorption. <br />Material and Methods: Twenty primary teeth were examined, Ten exfoliated teeth with physiological resorption represented Group I and ten extracted teeth with coexistent physiological and pathological resorption represented Group II. <br />Results: At light microscopic examination, group I showed deep round wave like resorption fossae filled with many odontoclasts, and the pulp showed inflammatory cell infiltration along with areas of dystrophic calcification. The odontoblasts were disorganized or disappear completely. Repair by cementum like tissue deposition was found internally. SEM examination revealed variable sized numerous resorption lacunae with smooth edges that had a circular or polygonal shape. Group II showed irregular resorbed root surface and various size odontoclasts besides thick granulation tissue. The pulp was degenerated, necrotic and contained calcification globules. The odontoblastic layer couldn’t be identified. Cementum repair was evident externally but at the internal resorption surface. By SEM, the resorption fossae were smaller and irregular in shape with thinner edges.<br />Conclusion: There were various morphological differences between physiological and coexistent physiological and pathological resorption of human primary teeth

Introduction: Nanoparticles have different effects on humans as they have specialized characteristics from the bulk materials. Zinc oxide nanoparticles are most commonly utilized nowadays due to their unique characteristics. On the other hand Zinc oxide nanoparticles have been found to have adverse effects on humans as cytotoxicity so it is a double-edged sword. Quercetin is a flavonol with beneficial anti-oxidant and antiinflammatory effect. Aim :The present work aimed to investigate the effects of Zinc oxide nanoparticles on rat submandibular glands and to evaluate the prophylactic effect of Quercetin . Materials and Methods: Twenty four male rats were equally divided into three groups: group A control, group B treated with Zinc oxide nanoparticles and group C treated with Zinc oxide nanoparticles and Quercetin for twenty eight days. Results: At the end of the study, rats were sacrificed and the effects of Zinc oxide nanoparticles as well as the prophylactic role of Quercetin on the submandibular glands were evaluated by light microscopy. The cells of the acini in group B revealed signs of cytotoxicity as loss of the acinar architecture, apoptotic nuclei, and cytoplasmic vacuolation while, in group C submandibular glands showed accentuated preservation in the cells of the acini and ducts that was comparable to that of the controls. <br />Conclusion: This experiment clarified that Zinc oxide nanoparticles has a cytotoxic effect and illustrated that prophylactic administration of Quercetin efficiently counteracted the toxic effect of Zinc oxide nanoparticles administration in rat models. Therefore, Quercetin can be prophylactically used to prevent Zinc oxide nanoparticles cytotoxicity.

Aims: To evaluate the expression of Cyclooxygenase-2 (COX-2) in odontogenic keratocyst (OKC) and dentigerous cyst and correlate it with Ki-67 expression in these lesions.<br />Material and Methods: This study was carried out on 32 paraffin embedded specimens of dentigerous cyst and OKC. 16 samples obtained from healthy mucosa served as controls. Slides prepared from paraffin-embedded sections were immunohistochemically stained for Ki-67 and COX-2 and immunoreactivity of the two markers was evaluated using index of positivity and staining intensity. Statistical analysis was performed using Mann-Whitney and Spearman’s correlation tests.<br />Results: Ki-67 and COX-2 expression in OKC and dentigerous cyst was found to be significantly higher than those observed in healthy mucosa groups (p < 0.05). The expression of the two markers was significantly higher in OKC than in dentigerous cyst. A positive correlation was found between the two markers in both lesions.<br />Conclusions: Increased expression of Ki-67 and COX- 2 in OKC is an indicator of the high mitotic activity of these lesions compared with dentigerous cyst. COX-2 is implicated in odontogenic epithelial proliferation in OKC and dentigerous cyst.

Aim of study: The aim of this study was to compare the effect of Xenograft alone or in combination with Platelet rich fibrin (PRF) in the treatment of mandibular furcation grade II defects.<br />Patients and methods: Twenty patients with a total number of 40 grade II furcation defects in split mouth design determined clinically and radiographically were selected for the study. The selected sites were treated with open flap surgery and divided into two groups: Group I was treated with Xenograft (cerabone®) only and Group II treated with Xenograft (cerabone®) plus PRF membrane. The clinical and radiographic evaluation occurred at baseline (before surgery) and 6 month post-operative. Clinical parameters include: plaque index (PI), gingival index (GI), vertical clinical attachment level (VCAL) and Horizontal clinical attachment level (HCAL). Cone-beam Computed Tomography (CBCT) was performed to measure furcation height (FH), width (FW), and depth (FD) defects of mandibular molars at baseline (before surgery) and 6 month post-operative.<br />Results: Both groups showed statistically significant reduction in all clinical and radiographic parameters within groups from baseline to 6 months post-operative. HCAL, FH, FW and FD were significantly increased in G II compared to G I at 6 months post-operative.<br />Conclusion: Treatment of furcation grade II defects with xenograft (cerabone®) plus PRF led to significant improvement more than xenograft (cerabone®) alone.

Introduction: Periostin is a matricellular protein highly expressed by the fibroblasts in the periodontal ligament. It is entangled in the maintenance of periodontal integrity which is affected by periodontal disease.<br />Aim: this study aimed to compare both GCF and salivary periostin levels during periodontal disease to their levels after non- surgical periodontal therapy.<br />Subjects and methods: The present study was performed on a total of 30 subjects, 13 males and 17 females. The thirty selected participants were sampled at baseline and after receiving the non-surgical periodontal treatment.<br />Results: In GCF, there was a statistically significant (at P ≤ 0.05) increase in mean Periostin level after treatment. While in saliva, there was a statistically significant (at P ≤0.05) decrease in mean Periostin level after treatment. <br />Conclusion Our results suggested that GCF periostin level may be considered as a reliable marker in the evaluation of periodontal disease activity, while salivary periostin level could have a promising diagnostic potential. So, further investigations are recommended.<br />

Background: Magnetic resonance imaging is the chief imaging modality used in assessment of temporomandibular disorders.<br />Aim of the study: This study aimed to investigate the validity of Volume ISotropic Turbo spin echo Acquisition (VISTA) pulse sequence in the assessment of temporomandibular disorders.<br />Subjects and Methods: Fifteen patients with temporomandibular joint related complaints performed MRI bilaterally using VISTA proton density and two-dimensional proton density turbo spin echo pulse sequences. Four-point scale was used to assess the clarity of articular disc position, disc morphology, cortical bone delineation, and overall image quality of both tested techniques. Besides, the final diagnosis of each case was obtained.<br />Results: The main and standard deviation of traditionally used 2D proton density images in determination of disc position, disc morphology, delineation of cortical bone and overall image quality were (2.57± 0.49), (2.37± 0.60), (2.8± 0.4), (2.57± 0.49), respectively. While those for VISTA images were (1.8± 0.4), (1.53± 0.72), (2.1± 0.60), (1.7± 0.64) with the same order. The final diagnosis was similar in both techniques in 25 cases out of 30.<br />Conclusion: Volume ISotropic Turbo Spin Echo Acquisition (VISTA) magnetic resonance pulse sequence could reveal the temporomandibular joint related structures, but with less image quality than that of traditionally used two-dimensional proton density images.

Objectives: Our aim in the current study is to evaluate the level of high sensitivity C-reactive protein in serum of patients with periodontitis and type 2 diabetes before and after non-surgical periodontal treatment.<br />Subjects and methods: 60 individuals in total with stage II grade A generalized periodontitis (n=20) and stage II grade B generalized periodontitis with type 2 diabetes (n=20) along with healthy control subjects (n=20) were enrolled in this study. Serum samples from all participants were obtained. Two serum samples, before & after non-surgical periodontal treatment, were gathered from patients with periodontitis and periodontitis with type 2 diabetes. Only one serum sample was collected from healthy controls. Enzyme linked immunosorbent assay technique (ELISA) was used to measure serum levels of high sensitivity C-reactive protein (hs-CRP).<br />Results: The highest concentration of serum hs-CRP was detected in patients with periodontitis & type 2 diabetes. This is followed by periodontitis group and then controls subjects. A statistical significant reduction in the hs-CRP serum levels after non-surgical periodontal treatment was detected in periodontitis with diabetes group while the periodontitis group showed similar reduction but without statistical significance. High diagnostic accuracy of serum hs-CRP was revealed by the Receiver Operating Characteristic (ROC) curve analysis, especially when comparing periodontitis patients, with or without diabetes, with the control.<br />Conclusions: Serum hs-CRP could be utilized as a prognostic marker in patients with periodontitis and type 2 diabetes.
