Aim: The aim of this study was to evaluate the facial soft tissue changes in skeletal anterior open bite patients treated with rapid molar intruder appliance using cone beam computed tomography (CBCT).<br /> Materials and Methods: This retrospective study included 2 groups. The first treatment group included randomly selected CBCT scans of 20 skeletal open bite patients (8 males and 12 females, mean age 11.6±1.1 years) who were treated with the rapid molar intruder appliance (RMI) for molar intrusion. The CBCT scans were taken before treatment (T1) and after open bite correction (T2). The facial soft tissue changes in the treatment group were compared with a closely matched second untreated control group with normal anterior overbite (9 males and 11 females, mean age 11.9± 1.2 years).<br /> Results: The first group showed significantly greater decreases in the angle of facial convexity and the H angle than the second group. The first group showed significantly greater increases in the lower lip protrusion and the soft tissue chin prominence than the second group. The upper lip protrusion and the soft tissue facial height were decreased in the first group and increased in the second one. The difference was statistically significant. The nasolabial angle was increased in the first group and decreased in the second one. The difference was statistically significant. <br /> Conclusions: Molar intrusion using the rapid molar intruder appliance (RMI) could result in significant improvement in the facial soft tissue profile in skeletal anterior open bite patients.

surface treatment is one of the most important factors that affect the bond strength of composite resin restorations. Lasers have been studied as surface pretreatment agents with limited applications in primary teeth. Primary enamel pre-conditioning using Er, Cr:YSGG yielded controversial results as regards to enhancing enamel bond strength of composite resins to primary enamel. <br /> Aim: The aim of the study is to evaluate and compare the shear bond strength of composite resin bonded to enamel which is pretreated using conventional phosphoric acid etchant and Er,Cr:YSGG laser.<br /> Materials and Methods: Thirty extracted human primary molar teeth were divided into three groups, (N=10) in each (Groups I,II and III). Group I, prepared surface of enamel was etched using 37% phosphoric acid (Scotchbond, 3M). Group II, enamel was surface treated by an Er, Cr: YSGG laser system (Waterlase MD, Biolase Technology Inc., San Clemente, CA, USA) and Group III, a combination of etching and laser treatment was performed. The bonding agent (Scotchbond Multipurpose, 3M) was then applied over the test areas and light cured. Composite resin (Filtek ™ Z250 XT Nano-hybrid Universal restorative, 3M Espe) was later applied and light cured. The samples were finally tested for the shear bond strength.<br /> Results: The Mean shear bond strength for Group III was the highest (23.2 ± 0.44MPa) Followed by Group I (17.4 ± 0.66MPa), these values were significantly higher (P < 0.01) than that of Group II (10.1 ± 0.71MPa).<br /> Conclusion: ER,Cr.YSGG laser pretreatment of primary enamel cannot replace the acid etching.

Abstract:<br /> Many studies in literature showed the effectiveness of silver diamine fluoride (SDF) and Nano silver fluoride (NSF) as preventive agents. However, there is little evidence regarding the retention properties of fissure sealant (FS) when applied on a surface previously treated with these preventive agents. <br /> Objective: To evaluate and compare the effect of fissure pre-treatment with SDF versus NSF on the microleakage of FS in permanent teeth. <br /> Methods: This experimental in vitro study was performed on 45 extracted human premolars, teeth were randomly assigned into three groups according to the type of fissure treatment: Group I: Control group (sealant only), Group II: SDF group (pre-treatment before sealant), and Group III: NSF group (pre-treatment before sealant). Teeth were thermos-cycled and then immersed in 2% methylene blue solution for 24 hours, teeth were then sectioned mesio-distally in the middle of the fissure, and examined under the stereomicroscope for dye penetration. Results: There was no statistical significant difference in the microleakage scores between the three groups (p=0.247). Conclusion: Pretreatment of the pits and fissure with SDF or NSF prior to sealant application did not affect the micro-leakage of the FS.

Objective: This study aimed to determine whether orthodontically moved maxillary canines exposed to two different protocols and dosage of LLLT exhibited differences in amount and rate of tooth movement.<br /> Materials and Methods: Fifteen patients, 12 females and 3males, with mean age of 17.48 ± 2.95 years were included. They had a clinical indication for bilateral extraction of first maxillary premolars. Using a split mouth design, maxillary left and right sides were randomly divided into two groups. In group 1, LLLT delivered at 10 points; 5 from buccal and 5 from palatal aspects with total dose of 8 J/session. In group II, laser applied from buccal side only at 5 points with dose of 4 J per session. In both protocols, gallium aluminum-arsenide diode laser applied in continuous mode with 635 nm, 100 mW, 25 J/cm2, 8 seconds/ point, 0.8 J/point. Amount and rate of maxillary canine retraction and degree of anchorage loss were determined by intraoral and three-dimensional digital models measurements. <br /> Results: Clinical and model evaluations demonstrated no significant difference (p˃ 0.05) between both groups. After 24 weeks, total amounts of canine retraction were 6.86±1.60 mm and 6.65±1.59 mm in group I and group II, respectively. Moreover, anchorage loss displayed -0.35 mm ± 0.18 mm in group I and -0.44 mm± 0.24 mm in group II.<br /> Conclusion: With the current settings, both protocols and energy doses of LLLT accomplished comparable amount and rate of maxillary canine retraction. Additionally, they displayed an equivalent minimal degree of anchorage loss.

Forensic odontology is an investigative aspect of dentistry that apply dental knowledge for legal issues including identification of unknown human bodies or remains. Sexual dimorphism of permanent teeth measurements has been extensively studied but, no studies involved pediatric age group with mixed deciduous and permanent dentition. <br /> The aim of this study was to determine accuracy of maxillary and mandibular deciduous and permanent molar teeth in sex determination in a sample of Egyptian children. Additionally, to estimate crown size of mandibular permanent first molar from mandibular deciduous second molar.<br /> A sample of 210 male and female children aged 6-12-years, in mixed dentition stage. Mesio-distal (MD) crown diameters of maxillary and mandibular permanent first molars and deciduous second molars were measured by a digital caliper. <br /> The mean MD crown diameter of both Rt maxillary and mandibular permanent first molars was significantly higher in males than females (10.29±.31 vs10.00±.60 and 11.01±.51 vs10.71±.60 respectively, p < 0.001). Furthermore, Rt and Lt mandibular deciduous second molars exhibited significantly larger mean MD diameter in males (9.94±.44 and 9.98±.42) than females (9.71±.46 and9.74±.46). Further, Simple linear regression revealed new equations for prediction of crown size of mandibular Rt permanent first molar from mandibular Rt deciduous second molar.<br /> Odontometric study of deciduous and permanent molar teeth showed poor accuracy in sex determination. They can be used in conjunction with other traits to establish gender accurately. Furthermore, this work presented new equations that will be helpful in estimating crown size of mandibular permanent first molar from mandibular deciduous second molar.

Introduction: Teeth eruption is a dynamic, genetically process which is a part of the odontogenesis and comprises all the tooth movement from the bone crypt until reaching the occlusal plane and starting its function. Objectives: The present study was carried out to determine the eruption dates of permanent teeth, also to study bilateral and maxillo-mandibular differences in the eruption of teeth and finally to assess sequence of permanent teeth eruption among a group of children in El Gharbia governorate. Methods: The study sample consisted of 1000 healthy Egyptian children of both sexes aged from (5- 12 years) were selected from different urban and rural primary schools. They were examined by tongue depressors in the day light, mouth mirrors and light torch for recording presence or absence of teeth. Results: The first permanent tooth to erupt was the lower first molar, erupted at 7.30, 7.41 years in girls and boys respectively and the last tooth to erupt was the maxillary second molar, erupted at 11.23, 11.26 years in girls and boys respectively. Also there were no statistically significant gender differences in mean eruption ages of permanent teeth except lower canine and no significant jaw differences except incisors in both girls and boys &canines and lower second molar in girls. Finally there were insignificant differences between right and left sides in permanent dentition. Conclusion: The eruption dates of permanent teeth are delayed in EL-Gharbia governorate compared to other studies. Girls preceded boys only in lower canine

Aim: The purpose of this study was to systematically assess the quality of evidence supporting fluoride's alternatives for treating early enamel caries. Methods: A broad search strategy using PubMed and other sources was performed. For sensitive search strategy, we used MESH database and the following search queries: (‘‘Remineralization’’ [Mesh] OR ‘‘Remineralisation’’) AND (‘‘Caries’’ [Mesh] OR ‘‘Decay’’) AND (‘‘Fluoride’’). Predetermined criteria were: parallel, randomized, controlled trial studies with 6 to 18 years old children. Results: 1919 articles from PubMed advanced search were initially revealed then 79 papers were picked up, in addition to 536 from other sources. One paper only removed as a duplicate (by the author, title and reference). The remaining articles were indicated for closer assessment. Out of 614 papers were screened by title, only 29 met the inclusion criteria of this review. Additional screening by abstract was done independently by the three researchers to result in 7 articles. Conclusion: From this review, there is moderate clinical evidence to support preventive agents as fluoride substitutes. This review suggests the use of resin infiltration and fluoridated Miswak as remineralizing agents.

Aim: To assess level of orthodontic outcome literacy in terms of risks and benefits among patients undergoing active treatment.<br /> Materials and Methods: Descriptive cross-sectional study at King Abdulaziz University Faculty of Dentistry. Questionnaire was distributed to orthodontic patients using convenient sampling method. Demographics and perceptions of risks and benefits were collected. Descriptive statistics were reported in frequency and percentage.<br /> Results: A total of 113 participants from KAUFD orthodontic clinics. Majority were 59% females, 59% children and adolescents and 66% were Saudi. Referrals from 49% dentists, 30% self-referral and 20% parents. The main reason for seeking treatment was 47% esthetics, 27% function and 13% stability. Respondents perceived orthodontic risks as 30% painful, 55% uncomfortable, 43% result in ulcer, 38% cause white spot lesion, 45% caries, 8% root resorption, 11% gingival recession, 38% mobility and 56% relapse while 75% believed in their role in preventing adverse events. They perceived benefits as 94% better smile, 90% better bite, 85% straight teeth, 60% teeth remain straight forever, 90% look better and 78% attractive profile. Reported previous knowledge 66% risks and 70% benefits and 20% signed a consent form.<br /> Conclusion: lack of orthodontic treatment outcome literacy could create an understanding barrier resulting in compromised compliance and treatment outcome. Findings recommended providing adequate information using consent form and proper communication about benefits and risks prior to initiating any orthodontic treatment. Further studies to evaluate effectiveness of such methods, compare perception to prevalence in terms of risks and benefits and their influence on treatment decision are recommended.

Background: Little prevalence studies relating to molar incisor hypomineralization (MIH) exist for Middle East populations in general and among Jordanian children in particular.<br /> Aim: To assess the prevalence and severity of MIH in a group of 3rd year class school children resident in Amman, Jordan as well as to describe its distribution in first permanent molars and incisors.<br /> Methods: A cross-sectional study with a representative sample was used. A simple random sampling technique produced 1412 school children aged 8-9- years. All children were examined by a single calibrated examiner. The first permanent molars and incisors were examined for molar incisor hypomineralization using the chart of Ghanim et al. based on the criteria of European Academy of Paediatric Dentistry (EAPD). Analysis of data was performed with a p value set at 0.05.<br /> Results: Of a total of 1412 schoolchildren 186 (13.17%) were diagnosed with MIH. Maxillary teeth were more commonly affected than the mandibular but the difference was not significant (p>0.05) and the maxillary molar was the most affected. Demarcated creamy white opacities were most frequently encountered followed by post eruptive breakdown. Atypical restorations and caries because of MIH were uncommon. More than the half of teeth was diagnosed with severe form of MIH. The severity increases with the increase of number of affected molars. <br /> Conclusion: Molar incisor hypomineralization was high among the children examined. Demarcated opacities were more frequent than breakdown. The severity of the lesions increased with the number of affected teeth.

Most Oral Health Related Quality of Life (OHRQoL) orthodontic research focused on examining the relationship between malocclusion/orthodontic treatment need and OHRQoL amongst children, adolescents, and occasionally young adults. Very few studies evaluated such a relationship in adults 18 years and above, despite the increased demands for orthodontic treatment among this age group. The aim of this paper is to examine the association between five occlusal traits and perceived OHRQoL in adults while considering age and gender differences. This was an epidemiological observational cross-sectional study of adults aged 18 years and above during their routine visit to primary care dental centers in Jeddah, Kingdom of Saudi Arabia. A cluster sampling approach was employed. One-hundred participants were recruited. Participants completed the self-administered Arabic OHIP-14. Five occlusal traits were recorded during clinical examination by three calibrated examiners, including: missing teeth, overjet, crossbite, maximum displacement of contact point, and overbite. Student t test and ANOVA were used to test for statistical significance. There seemed to be a trend for reduced impacts on OHRQoL with age. Gender differences were noticed, but were not statistically significant. Of the five occlusal traits tested, only missing teeth and overjet were significantly associated with worse OHRQoL. The study confirms the association between malocclusion and OHQOL in older adults. However, the results need to be examined in other population to confirm the direction and magnitude of this impact.

Objective: To determine the prevalence and severity of malocclusion and orthodontic treatment needs among Tanta secondary school students and to analyze the relationship with gender and type of school. Methods: The study followed the World Health Organization recommendations for oral health surveys. Stratification of the sample was performed according to the district, type of school, and gender. The sample comprised 668 school students (290 males and 378 females) using the indexed age of 15 years. Mean, standard deviation, minimum, and maximum of DAI scores were calculated. Also, data were analyzed with regard to gender and school type using the chi-square test. Results: 78.7% of the examined students had normal occlusion with no treatment indicated. Meanwhile, students with definite, severe, and handicapping malocclusion in need of elective, highly desirable, and mandatory orthodontic treatment accounted for 14.1%, 4.2%, and 3% respectively. The mean DAI score of all the examined students was 22. There were no statistically significant associations between gender or school type and the severity of the malocclusion (p>0.05). Conclusion: the present results emphasized that the majority of secondary school students have normal occlusion while those with severe or handicapping malocclusion represent minorities.

Aim: compare the labio-palatal position of maxillary impacted canines (MICs) on CBCT and their mesiodistal position on panoramic radiographs. Materials and Methods: This retrospective radiographic study reviewed 70 radiographs with MICs (40 bilaterally and 30 unilateral). Radiographs with, odontoma, mesiodenses, or cleft lip and palate were excluded. The mesiodistal position of the MICs was classified into four sectors on panoramic radiograph while their labiopalatal position were evaluated on CBCT. The correlation between panoramic sectors location and CBCT results was examined using the chi-square test. Results: Labial positioned MICs on CBCT were more frequent in panoramic sector 1, while palatally positioned MICs were more frequent in sectors 4. The association between sectors of the MICs on panoramic images and the labio-palatal position of the MICs on CBCT was statistically significant (P < 0.001). Conclusions: This study showed that, sector location on panoramic radiographs might be used for prediction of labiopalatal position of MICs.

A well-executed orthodontic treatment has accurate root positioning as an integral pillar for its success. Unfortunately, contemporary methods used to visualize root positions are flawed in accuracy, resolution or excessive amount of radiation. This study was carried out to visualize the root position with a less radiation dose. At “Timepoint 0” a Cone-Beam Computed Tomography (CBCT) was taken for the patient before the start of the treatment. At “Timepoint 1” a CBCT was taken as a Reference Standard along with a digital extra-oral scan. A Predicted Root Position (PRP) assembly was made and compared to the Reference Standard to detect discrepancies between both. Mesiodistal tip analysis after indirect superimposition found displacement differences of 1.85 ± 1.09mm for the maxillary roots and 1.79 mm ± 1.16 mm for the mandibular roots. For buccolingual torque, displacement differences of 2.13 ± 1.52mm for the maxillary roots and 2.29 mm ± 1.59 mm for the mandibular roots. For root tip displacement, displacement differences of 1.57 ± 0.86mm for the maxillary roots and 1.44 mm ± 0.82 mm for the mandibular roots.

ABSTRACT<br /> Dentist anesthetists are always recommending the use of local anesthesia (LA) during tooth extractions to block any noxious stimulus and maintain the child vital signs with minimal interference. Objective: To evaluate the effect of intraligamentry anaesthesia (ILA) in reducing child pain and maintaining the vital signs during mandibular primary molars extraction under general anaesthesia (GA). Study design: A split-mouth controlled randomized clinical study was performed on 20 healthy children age ranging from 4-5 years indicated for complete oral rehabilitation under GA, with at least two bilateral mandibular primary molars indicated for extractions. A total of 40 primary molars were extracted, teeth were randomly assigned into two groups: Group A (extraction with ILA) and Group B (extraction without LA). Heart rate (HR) and mean arterial blood pressure (MABP) were used as parameters of pain, they were recorded before extraction (baseline data), and during the extraction procedure. The need of anesthetist intervention during extractions was also recorded. Results: There was no statistically significant difference between the baseline vital parameters (HR, MABP) and during extraction using ILA (p= 0.195, p=0.133 respectively). There was a statistically significant increase in the vital parameters (HR, MABP) during extractions without LA compared to both the baseline and during extraction using ILA (p= 0.000*). The need of anaesthetist intervention was statistically greater when extracting without LA than during extraction with ILA (p=0.00026).

Objective:<br /> This study was designed to evaluate the effect of occlusal splints used for treatment of tempromandibular disorders (TMD).<br /> Material and methods:<br /> Thirty class I malocclusion patients (ranging in age 20-30) suffering from signs of TMD attending at orthodontic department, faculty of dental medicine, Al Azhar university boys branch. The patients' complaints were crowding of teeth, limited mouth opening, tempromandibular joints (TMJ) pains, and joint noises during function. The patients will be divided randomly into three groups. Group I will have patients treated by hard rigid occlusal splint (heat cured tooth borne and occlusal surface). Group II will have patients treated by soft occlusal splint flexible and pliable tooth borne and occlusal surface. Group III will have patients treated by dual laminated occlusal surface, hard acrylic resin and soft material on tooth borne surface. Clinical evaluation was performed before the delivery of the splint and at 2, 4, 6 months. Maximum mouth opening and joint sound were recorded each follow up visit.<br /> Results: <br /> All groups of the study showed improvement in maximal mouth opening, TMJ pain, and clicking sounds with variable degrees according to treatment method.<br /> Conclusion:<br /> Dual laminated occlusal splint seemed to be superior in achieving rapid and prolonged improvement in TMD patients than other splints.

Periapical lesion is the most common sequelae of pulp necrosis due to either carious involvement or trauma. Treatment options to manage periapical lesion with open apex ranges from non-surgical root canal treatment and/or apical surgery to extraction. Objective: clinicall and radiogrphicall evaluation of the effect of MTA and bioceramic root canal sealer to manage immature permenant teeth with open apex. Methodology: The study was composed of sixty teeth from 54 children with age ranged from seven to ten years old age. Children were divided in to two equal groups: 1-Group A:Teeth were received apexification with MTA 2-Group B:Teeth were received apexification with bioceramic root canal sealer. All patients were followed clinically and radiographically immediate postoperatively, 3 and 6 months. Results: The success rate in both bioceramic and MTA was 93.3% and 90% respectively with no statistical significant difference. After 6 months, all teeth shows normal lamina dura among both bio ceramic and MTA groups. While, reduced radiolucences and obvious healing of bone detected among 93.3% and 90% of tooth among bio ceramic and MTA groups respectively. Conclusions: Both MTA and bioceramic sealer show good results

Aim: To consider the ability of mothers to screen caries in their special health care needs (SHCN) children after attending an educational training program.<br /> Subjects & Methods: A study involving 100 mothers of SHCN children aged 4 - 6 years old seeking treatment at the general anesthesia unit of Egyptian Society for Pediatric Dentistry and Children with Special Needs (ESPSN)-Faculty of Oral and Dental Medicine-Cairo University. Mothers of SHCN children were trained in a 3 hours training program by the researchers to detect caries in their children using power point presentations, and flash cards. Mothers were trained to screen caries according to the WHO (1997) criteria for caries diagnosis. After the training program, all mothers performed caries screening on their own children. The findings were checked for validity by comparing mothers’ findings with researchers’ findings as the gold standard.<br /> Results: The overall prevalence of caries in the sample was 90%. The sensitivity, specificity, positive predictive value and negative predictive value of mothers’ caries screening were 94.4%, 70.0%, 90.8% and 81.5% respectively. <br /> Conclusions: It was feasible to train mothers with basic skills to screen dental caries in their special health care needs children. This prospect might provide a substantial future venue, giving mothers of children with SHCN a chance to seek dental treatment early and thus avoid further complications and extensive treatment.
