The ability of reduced graphene oxide (rGo) in regenerating bone tissue has recently gained significant attention in biomedicine. Aim: we investigated the effects of rGo nanoparticles and platelet rich plasma (PRP) in regenerating induced defects in irradiated 2 types of rat bones. Materials and Methods: We had 4 experimental rat groups, each was 6 in number, all of them were irradiated then a bone defect was surgically induced at the condyle representing endochondral bone and ramus representing intramembranous bone in each rat. The bone defect was then grafted with rGo alone in (GpI), PRP alone in GpII, combination of PRP and rGO in GPIII or left ungrafted as a control in GpIV. 8 weeks later samples were explanted for histological studies. Results: All groups showed bone formation with highest organized bone formation in GPIII. Conclusion: regeneration of irradiated bony defects using the combination of rGO nanoparticles and PRP can provide the highest active healthy bone formation.

Fahd
Ankylosis is one of the challenging disorders of the TMJ especially in children. Trauma, infection, and systemic diseases are the most common causes, factors common to occur in children in Upper Egypt. Unfortunately, TMJ ankylosis responds only to surgical intervention. The aim of this study was to evaluate a conservative surgical approach. Materials and Methods: In this study inclusion criteria were set and 11 children suffering from ankylosis enrolled for the most conservative gap arthroplasty without interpositioning material and with postoperative physiotherapy protocol. The patients were evaluated clinically and radiographically for 24 months postoperatively regarding mouth opening and recurrence. Results: trauma was the main etiologic factor and bony ankylosis accounted for 81%, the mean gain in mouth opening was 29mm with no reported recurrence. Conclusion: using conservative gap arthroplasty in children is a success option within the justified inclusion criteria.

Purpose: The purpose of this research was to compare the effectiveness of platelet rich fibrin (PRF), alvogyl and zinc oxide/ eugenol (ZOE) intra-alveolar dressings for pain relief and socket healing (Epithelialization) in dry socket management and to study relevant epidemiological features.Patients and methods: A total of 45 patients with alveolar osteitis were randomly divided into three groups; Group (A) patients received PRF, Group (B) patients received Alvogyl and Group (C) patients received ZOE dressing. All the patients were evaluated for Pain (VAS), degree of inflammation, healthy granulation tissue formation and number of exposed socket walls (socket epithelialization) at 1st, 3rd, 7th, and 14th post-operative day. Results: Group A (PRF) showed better and faster socket healing than Group B and C. However, symptomatic pain relief was faster in Group B (Alvogyl) than in Group A and C.Conclusion: PRF in this study illustrates the promising results to be used effectively as the suitable dressing material in the management of alveolar osteitis. PRF treated cases showed a shorter time required for complete and fast clinical healing.

Background: odontogenic keratocyst is classified as a developmental cyst derived from enamel organ or from dental lamina. Treatment of odontogenic keratocysts of the jaws remains controversial. Aim of study: was to report the outcome of a conservative treatment protocol in the form of enucleation with open packing for surgical treatment of parakeratinized odontogenic keratocysts.Methods: after clinical and radiographic examination, fine needle aspiration was obtained from lesions and submitted for histopathological examination. Then the patients were treated by enucleation and open packing. This conservative treatment protocol was selected to decrease the morbidity rate in young aged patients. The follow-up duration of the cases was 2 years. All the cases were monitored continuously with clinical evaluations and radiographically through Orthopantomographs (OPG) and Cone beam computed tomography (CBCT).Results: Clinical evaluation showed healing improvement of the surgical site with no signs of infection. Radiographic examination showed newly formed bony trabeculation at surgical site.Conclusions: This conservative treatment protocol for odontogenic keratocysts based on enucleation with open packing would be a possible choice with a view of offering low recurrence rate and low morbidity rate particularly in young patients.

Aim: The aim of this study was to evaluate the improvement of function and reduction of recurrence rate in patients with bilateral temporomandibular joint ankylosis treated with costochondral graft and interpositional fat compared to costochondral graft alone. Materials and Methods: This was a randomized controlled trial conducted on 10 adult patients with bilateral TMJ ankylosis. In control group, TMJ reconstruction was performed with costochondral graft after gap arthroplasty. While in the intervention group, the same procedure was performed with the addition of autogenous abdominal fat graft as interposition material. All patients were followed up for at least 6 months. The primary outcome was the percentage of patients with reankylosis in each group. The secondary outcome was the change in maximal incisal opening (MIO) after 6 months. Results: Both groups showed no recurrence. Intervention group showed lower change in the MIO (1.8 ± 0.84 mm) compared to the control group (2.4 ± 0.89 mm). Conclusions: Interpositional abdominal fat with costochondral graft TMJ reconstruction for management of bilateral temporomandibular joint ankylosis was found to be beneficial with promising results regarding maintained gained range of mandibular function, with relapse avoidance. However with no evidence of recurrence in any of our cases and the non significant difference in MIO, its superiority over costochondral graft TMJ reconstruction has not been proved yet.

Objective: The purpose of this research was to compare the effectiveness of intra-alveolar platelet rich fibrin (PRF) and chlorhexidine gel for pain relief and quality of socket healing (Epithelialization) with prevention of dry socket after the surgical removal of impacted third molars.Patients and methods: A total of 30 patients (17 males and 13 females; with a mean age of 30 years). who required extraction of impacted third molars were randomly divided into three groups: PRF group ; PRF were placed in the extraction sockets ,chlorhexidine CHX gel 0.2% group ; 1 ml CHX were placed in the extraction sockets and control group, while the sockets remained empty. All the patients were evaluated for Pain (VAS), degree of inflammation, healthy granulation tissue formation and number of exposed socket walls (socket epithelialization) , dry socket incidence and maximum interincisal mouth opening MIO at 1st , 3rdand 7th, post-operative day. Results: In the PRF group, a significantly less pain was recorded in the third and seventh postoperative days (P = 0.003, 0.04) respectively. Group (PRF) showed better soft tissue and socket healing than chlorhexidine gel and control groups but non-significant difference was observed. PRF reduced the incidence of alveolar osteitis. .Conclusion: PRF in this study illustrates the promising results to be used effectively in the prevention of alveolar osteitis. PRF treated cases showed better response to postoperative pain, better clinical socket healing with reduction of inflammation and more improvement of maximum interincisal mouth opening MIO than chlorhexidine gel 0.2% after the removal of third molars.

Objective: This prospective randomized clinical study was designed to evaluate the efficacy of open cap splint versus split acrylic splint in management of pediatric mandibular fractures. Patients and Methods: Twelve pediatric patients with symphysis, parasymphysis, and body of mandibular fractures treated by closed reduction and fixation were randomly selected. They were divided randomly into two equal groups: group (I) patients were treated by open cap splint and group (II) patients were treated by the split acrylic splint. Postoperative clinical ,and radiographic evaluations were performed to assess complications, occlusal stability, pain on a visual analogue scale (VAS), maximum mouth opening, and the overall results of fixation up to 6 months. Results: Fracture healing was optimal in all cases, except two cases in group I presented malunion of the fractured bone. Satisfactory dental occlusion was observed in all cases, except two cases in group I, where they had mild to moderate occlusal derangement. Other parameters including maximal mouth opening, and pain level were comparable. Postoperative radiographic evaluation showed a complete union of the fractured segments at the end of six months in all cases. Conclusion: The results of the current study showed that, the open cap splint and split cap splint provided enough stability for proper bone healing, establishment of optimal occlusion, and early return to normal function with superiority for split cap splint.

Purpose: the aim of this study was to define the role of coronoid condylar index (CCI) in diagnosis of elongated coronoid process. Patients and Methods: Eight patients with unilateral coronoid hyperplasia were included in this study, six patients were males and two patients were females, their ages ranged from 19-28years with a mean of 23.5 years. All patients were evaluated both clinically (through detection of range of mouth opening, range of mandibular deviation towards the affected side, presence of palpable crepitation or audible grating in the TMJ and finally vision of movement of the coronoid process in the infratemporal fossa during mouth opening ) and radiographically (from the lateral projection three dimensional computerized tomography of the lower jaw). Results: regarding to the mouth opening, the mean of mouth opening for all patients was 25.3 mm. the mean of deviation of the mandible towards the affected side was 3.5mm. Palpable crepitation and audible grating of the temporomandibular joint had been detected only in three cases. Vision of the coronoid process movement in the infratemporal fossa had been detected only in four cases, particularly during mouth opening. Radiographic evaluation revealed, the mean of the coronoid condylar index (CCI) to all the examined patients was 1.22mm. Conclusion: The CCI is considered as simple and rapid method for determination of any discrepancy in both coronoid and condylar processes of the lower jaw.

Objectives: The aim of the current study was to evaluate clinical outcome of using piezoelectric device versus conventional surgical drills in surgery of TMJ ankylosis. Patients and methods: A prospective study included 18 joints in 10 patients suffered from bony ankylosis of the TMJ who were surgically managed by gap arthroplasty at oral and Maxillofacial Surgery department Minia University Dental Hospital (MUDH) and Dar Al Shifa hospital of Egyptian Ministry of health. Postoperative outcomes of TMJ surgery were investigated and compared based on the following parameters: Postoperative mouth interincisal opening, intraoperative bleeding, length of the operation time, surgical site infection, surgical site swelling and postoperative pain.Results: statistical analysis of reported data revealed that; in general there were statistical significant in increase in mouth opening for all patients. There were no significant changes between both groups in bleeding and surgical site infection score, however there were statistical significant increase in operative time and decrease the postoperative edema and pain score in piezoelectric device group.Conclusion: piezoelectric bone removal for the release of ankylosis of the TMJ reduced postoperative complications its main disadvantage is the increase in operating time. The piezosurgery allows surgeons to achieve better outcomes compared to a conventional surgery and its possible alternative due to the clinical benefits demonstrated.

Objectives: The current study was conducted to assess and compare 2 versus 4 implant supported mandibular over-denture using computer guided planning Material& methods: The study was conducted on 16 patients who had completely edentulous jaws. Patients were divided into 2 groups. Group A: 8 patients received 2-implant supported mandibular over-denture, and Group B: 8 patients received 4-implant supported mandibular over-denture using computer guided planning. After 4 months of healing, complete denture was connected to the implants with Locator attachment abutments. Clinical evaluation was performed through Visual Analogue Scale (VAS) to assess patients’ satisfaction after 12 months of loading. Radiographic evaluation was performed through CBCT to assess the marginal bone loss at 6, 12 months post-loading and posterior ridge resorption at 12 months post-loading. Statistical analysis of data was performed.Results: all patients were satisfied with range of 7-10 VAS with no difference between the study groups. Group A showed significant higher marginal bone loss than group B at 6, 12 months post-loading. Group A showed significant higher values of posterior ridge resorption at 12 months post-loading.Conclusion: increasing the number of implants from 2 to 4 in mandibular implant supported over-dentures leads to significant decrease in marginal bone loss, and residual posterior ridge resorption. But didn’t have significant influence on patient satisfaction after 12 months of function.

Does The Placement Of A Free Connective Tissue Graft In Conjunction With Immediately Placed Dental Implants In Fresh Extraction Sockets Preserve The Labial Marginal Bone Level? A Randomized Controlled Clinical Trial
Ahmed
Reda
Mohamed
El Baz
Background: The beneficial effects of simultaneous soft tissue augmentation along with immediate post-extraction implant placement in the esthetic zone have been clearly demonstrated regarding the preservation and maintenance of soft tissue architecture. However, the potential of soft tissue augmentation to preserve the vertical height of thin labial bone plates is not fully evident. Research question: Is it necessary to apply a soft tissue graft with immediate implants in the esthetic zone if preservation of the height of a thin labial plate is desired? Methods: Twenty patients with single hopeless teeth in the esthetic zone having thin facial bone plates (<2mm) were equally and randomly divided into 2 groups; (A) who received immediate implants only (control) and (B) who received immediate implants and connective tissue graft secured over the implant in split-thickness facial and palatal pouches (test). Amount of vertical marginal bone loss from the facial plate was measured over 6 months. Results: A statistically-significant difference (at P ≤ 0.05) existed between the mean values of vertical bone loss of both groups. The amount of vertical bone loss was limited more in the test group (B). Conclusion: Simultaneous soft tissue augmentation with immediate implants in the esthetic zone demonstrated beneficial effects regarding the preservation of the vertical level of thin labial plates.

Maggie
Khairy
Essam
Ashour
Aim of the study: This study aims to evaluate the efficacy of eminectomy versus T plate eminoplasty as two surgical maneuvers for treating temporomandibular joint subluxation.Patients and Methods: The study was conducted on thirty patients suffering from bilateral TMJ subluxation. Diagnosis was confirmed by taking history, clinical examination and Tmj view radiographs. They were divided into two groups where Group I performed eminectomy while Group II inserted a T plate at the anterior border of the eminence. Clinical data including maximal mouth opening, pain, joint sounds and recurrence of subluxation episodes were collected at 1 month,3 months,6 months ,12months and 24 months postoperatively. As for the radiographic assessment cone beams were taken preoperative to exclude presence of cysts within the eminence, right postoperative, 6months ,12 months and 24 monthsResults: All clinical data collected including maximal interincisal opening, pain, joint sounds and number of dislocations episodes per week showed initial improvement for the two groups but superior results were in favor of the T-plate group. Long term follow up proved the superior results of the plates with no associated side effects. On the contrary the eminectomy group showed some side effects ,the worst of all was the Tmj osteoarthritic changes detected in the CBCT within the condylar head .Conclusion: Both surgical techniques had good results concerning TMJ subluxation. However, the plate group had superior results and no proved side effects on the long run.

Niveen
Askar
Sherif
Ali
Aim: The aim of this study was to introduce and assess a new computer guided algorithm using locating holes and cutting guides, for mandibular segmental resection in cases with massive contour deformity. Patients and Methods: This was a prospective study conducted on 6 consecutive cases with mandibular odontogenic neoplasms indicating lateral segmental mandibular resection. For all the patients, computer guided resection and titanium plate reconstruction using locating holes and cutting guides was performed. The patients were followed up for 6 months; and recurrence, appearance, occlusion, maximum incisal opening (MIO), midline shift, chewing, swallowing, speech, pain were recorded. Results: No recurrence occurred in the study till the end of follow up period. 33.3 % of the observed minor change in appearance, and 66.7 % observed no appearance change. No major disruption in occlusion occurred for any patient. The mean MIO was 41.8 ± 4.35 mm after 1 month, 42.3 ± 3.98 mm after 6 months, with no statistically significant difference. Chewing, swallowing, and speech were as normal for 5 patients (83.3 %). Conclusions: The computer guided resection and titanium plate reconstruction using locating holes and cutting guides was found to be beneficial with promising results regarding function and aesthetics, we recommend the use of this technique for initial resection and reconstruction in delayed grafting. Yet, its use as a definitive reconstruction should be subjected to longer follow up period studies.

Iman
El-Asfahani
The aim of the current study was to evaluate efficacy of using iliac grafts combined with implants and retaining a provisional fixed-detachable (hybrid) prosthesis in the reconstruction of mandibular defects regarding average bone loss in graft height, peri-implant marginal bone loss, maximum bite force, facial asymmetry ,patient satisfaction and oral health quality of life (OHRQoL).Patients and methods: 11 patients were subjected to mandibular marginal resection with immediate reconstruction by autogenous iliac crest graft with implant placement. After 6 months they were rehabilitated with provisional screw-retained prosthesis. Radiographic assessment of average bone loss in graft height and marginal bone loss around dental implants was performed. Facial asymmetry, Maximum bite force, Patient satisfaction and oral health quality of life (OHRQoL) were assessed after the first surgery, at loading, 6 and 12 months later.Results: Average bone loss of graft height (mean 2.14±1.03). Average peri-implant Marginal bone loss after 1 year 1.42±0.38. The increase in marginal bone loss along the study period was significant (P<0.001). Maximum bite force of the rehabilitated side increased significantly along the study period. There was a statistically high significant difference between the scores of all OHIP-5 items scores except in the scores of the difficulty doing usual jobs item.Conclusion: Within the limitations of this study, it was concluded that construction of mandibular defect using iliac crest graft combined with dental implants and retaining a provisional fixed- detachable prothesis can be an effective procedure to restore bony defect, facial asymmetry, maximum bite force, patient satisfaction and oral health quality of life.

Evaluation of arthrocentesis with corticosteroids versus arthrocentesis with hyaluronic acid in the management of Temporomandibular joint osteoarthritis
Salah
El-Abbasy
Aim: to evaluate the clinical results, radiographic results and levels of inflammatory mediators following arthrocentesis with intra-articular injection of steroids versus arthrocentesis with intra-articular injection of hyaluronic acid in temporomandibular joint osteoarthritis.Materials and Methods: Ten patients suffering from Osteoarthritis with pain and crepitation during jaw movements together with radiographic evidence of bony erosions were included in the study. The patients were divided into two groups, five patients in group A were treated with arthrocentesis followed by intra-articular injection of corticosteroid and five patients in group B were treated with arthrocentesis followed by intra-articular injection of Hyaluronic acid. Results: Patients in both groups showed significant reduction in pain and increase in maximum mouth opening; however, arthrocentesis with intra-articular injection of HA showed better clinical results compared to arthrocentesis with intra-articular injection of corticosteroids. Less inflammatory mediators were found in the Corticosteroid group patients compared to HA group patients. No evidence of new bone formation was seen in both groups after 4 months postoperatively.Conclusion: Better clinical results were achieved after Arthrocentesis followed by intra-articular injection of hyalurionic acid when compared to arthrocentesis with intra-articular injection of corticosteroids. Less inflammatory mediators were associated with arthrocentesis with corticosteroids injection compared to arthrocentesis with HA injection. Long term follow up is required to be able to assess new bone formation following arthrocentesis with intra-articular injection of HA or corticosteroid.

The patients were scheduled for surgical removal of both impactions with 45 days interval in-between where side A impactions were performed using a piezotome and side B impactions were performed using conventional rotary instruments.Results: Comparing the overall outcomes of the present study and despite the increase in the operating time with the piezo surgery group, the postoperative pain, edema and trismus were significantly less in piezotome group compared to the conventional rotary group due to less heat generation, smoother osteotomy and decreased damage to the surrounding soft tissues provided by the piezotome.Conclusion: Comparing the overall outcomes of the present study,and despite the increase in the operating time with the piezo surgery group, the postoperative pain, edema and trismus were significantly less in piezotome group compared to the conventional rotary group due to less heat generation, smoother osteotomy and decreased damage to the surrounding soft tissues provided by the piezotome.
