Maxillary Central Incisors’ collum angle in different skeletal vertical malocclusions – A Cephaometric study
Introduction: The Collum angle can be defined as a crown root supplementary angle of maxillary central incisors. The aim of the study was to assess the maxillary central incisors’ collum angle in a sample of Egyptian patients with different vertical malocclusions using cephalometric radiographs. Methods: Ninety lateral cephalometric radiographs were collected and divided into three groups, with equal size, according to lateral cephalograms (SN-GoGn angle). Group І: consisted of lateral cephalmetric radiographs of 30 who had the strongest predominance of horizontal growth pattern (SN-GoGn ≤28º), Group ІІ: consisted of lateral cephalmetric radiographs of 30 subjects who had the strongest predominance of vertical growth pattern (SN-GoGn ≥35º). Angular and linear parameters on cephalometric radiograph for each subject were measured to identify the facial growth patterns, and Collum angle was then measured. Results: mean of collum angle for the maxillary central incisor in horizontal growth pattern sample was 7.8°±2.2° with minimum being 5° and maximum 14°. The mean values for vertical growth pattern was 2.1°±2.1° with minimum 0° and a maximum 6°. Paired samples t-test comparison revealed that there was a high significant increase in maxillary central incisor collum angle in horizontal growers than in vertical growers, mean difference being 5.7°±1°. Conclusion: Maxillary central incisor collum angle in horizontal growers is higher than in vertical growers.

Clinical And Radiographic Evaluation Of Biodentine Versus Formocresol In Vital Pulpotomy Of Primary Molars (A Randomized Control Clinical Trial)
Background: The main objective of pulp therapy is to preserve the integrity and health of the teeth and their supporting tissues, as well as to maintain the pulp vitality. Formocresol (FC) is that fixing agent which is considered as gold standard and used as pulpotomy medicament for primary teeth for decades. Several concerns had been reported about the use of FC. These concerns push new medicaments to be used for pulpotomy purposes. Among these medicaments is Biodentine (BD). Aim of the study: To compare FC and BD clinically and radiographically when used for pulpotomy of vital primary molars. Study Design : A randomized control clinical trial (split mouth and double blind) was conducted on 43 (4-6 years-old) children with decayed vital mandibular primary molars which were treated by pulpotomy using both medicaments . All treated teeth were followed for one year (at 3, 6, 9 and 12 months clinically and at 6 and 12 months radiographically). Results: BD showed 100% clinical and radiographic success at all follow up timing, however FC showed 85.4% and 78% radiographic success at 6 and 12 months follow up period . By clinical evaluation FC showed 95.1% success at the end of follow up period with no significant difference. Conclusions: BD as a pulpotomy medicament showed 100% clinical and radiographic success with no statistically significant difference with FC clinically. However a statistically significant difference was recorded between both medicaments regarding their radiographic success rate where BD was superior.

Velopharyngeal and Glossopharyngeal Volume Changes after Implant Anchored Maxillary Expansion
Purpose: Evaluation of the changes of the segmented 3D model of the pharyngeal airway volume and surface area after using conventional and hybrid Hyrax (with micro implant) for maxillary expansion using MIMICS software. Materials and methods: Sample size: 20 male patients with constricted maxilla dedicated for maxillary expansion as a part of orthodontic treatment plan. For each patient, written acceptance consent was taken to participate in the study. Selection criteria: - Age 12-14 years. - Absence of any: previous orthodontic intervention, breathing disorder, deformities that may affects the craniofacial structures. - Constricted maxilla indicated for Hyrax Rapid Palatal Expansion (RPX). The sample was divided into two groups: The first group (10 patients) was treated with conventional Hyrax appliance supported on first permanent molars bilaterally (dental anchorage). The second group (10 patients) treated with hybrid Hyrax supported on first permanent molar and first premolar bilaterally, this appliance incorporating two eyelets for additional skeletal anchorage with two micro-implants. For each patient enrolled in this study a full skull CT x ray was done just before the insertion of the Hyrax appliance and after 10 days of rapid palatal expansion at a constant rate for all patients. The full skull CT was processed via MIMICS software for segmentation, 3D modeling and measurements of the pharyngeal airway volume and surface area from the level of the hard palate to the lower border of the hyoid bone.Results: -For both conventional and Hybrid Hyrax, Rapid Palatal Expansion resulted in statistically significant increase in the pharyngeal airway volume and surface area (1.87cm3, 2.52cm3, 1,68cm2 and 2.48cm2) respectively. -Greater increase in the pharyngeal airway volume and surface area in the second group due to incorporation of the micro-implants but the statistical differences between both groups was found to be non-significant.Conclusions Both conventional and hybrid Hyrax produced significant increase in pharyngeal airway volume and surface area, this effect can be augmented by incorporating skeletal support (micro implant) in the Hyrax appliance.

Assessing the prevalence of early childhood caries and the associated determinants in a group of preschool children: results from a national oral health survey in Egypt
Objective: This study provides information on the prevalence of early childhood caries among a sample of Egyptian Preschool children and the potential determinants associated with this condition.Methods: A total of 651 preschool children were randomly selected from 160 gathering points in 26 governorates in Egypt. A face to face interview was conducted with children’s primary caregivers and data on socioeconomic status, oral hygiene practices and feeding habits was collected. Information on caries experience was also recorded through dental examination following a standardized clinical protocol based on World Health Organization measures. Results: More than 67% of the examined children had at least one decayed primary tooth and the mean dmf score was 3.3. Girls had lower mean dmf scores in comparison to boys. A weak positive correlation was detected between dmf scores in children and maternal caries experience (r = 0.130, P < 0.001) whereas the coorelation with frequency of tooth brushing was weak negative (r= -0.093, p<0.001).Conclusions: Dental treatment needs among Egyptian preschool children are quite high and thus urging actions towards promoting oral health status of this population group need to be undertaken at community levels.

Oral Health Status and Dental Treatment Needs of Preschool Children in 6th October City, Egypt
Aim: The aim of this study was to examine the oral health status, significant caries index and utilization of dental care among preschool children. Subjects and Methods: A cross sectional study was conducted on 581 children aged 2-5 years attending preschools and living in 6th October city, Egypt. The clinical examination of oral health status followed the World Health Organization’s guidelines for oral health surveys, 1997. Dental caries was determined using the decayed, missed and filled teeth (dmft) index. Significant caries index (SiC) and care index (CI) were also calculated. Tooth brushing habits at school and lunchbox contents of those children were also analyzed using a questionnaire distributed to pre- school teachers. Results: The overall prevalence of dental caries was 50.6% and the prevalence of early childhood caries was found to be 11.5%. The total mean dmft score of the examined children was 2.1±2.722 where the decayed component was dominant. The mean population SiC was 5.19±2.410 and the care index was found to be low with a mean of 6.2%. Visible plaque was found on tooth surfaces of 20.7% of the children and sugary snacks consumption was common among all children. Conclusion The prevalence of dental caries in this population was high and most of the decayed teeth were not treated. Implementation of oral health preventive and treatment campaigns is required to achieve optimal oral health in preschool children in this community.

Correlation of linear dimensions of sella turcica with anteroposterior skeletal jaw relationship of Egyptian subjects using CBCT
The aim of this retrospective study was to find whether there is a correlation between the linear dimensions of the sella turcica and different anteroposterior skeletal growth patterns in an Egyptian population using CBCT. CBCT radiographs of 129 adult patients (60 males, 69 females) were retrieved from the archive of the radiology department of the Faculty of Dentistry, Suez Canal University. They were divided into three groups according to sagittal growth pattern and the sella turcica length, depth and diameter were measured for each case. No statistically significant differences were found between all sella turcica measurements and the anteroposterior jaw relationship. The p-values were 0.087, 0.007 and 0.998 for the diameter, depth and length respectively.

Comparison of Dental Treatment Performed under General Anesthesia between Healthy Children and Children with Special Needs at a Teaching Hospital in Egypt
BACKGROUND: The evaluation of dental treatment under general anesthesia (GA) in healthy children and children with special health care needs (SHCN) should take into consideration; firstly, the different dental treatment needs according to the disability condition (scope of disability) and secondly, the limitation of the treatment. Aim of the study: This retrospective study aims at comparing the different dental treatment modalities performed under general anesthesia for healthy children, on one side, and those with special health needs, on the other. The Study was carried out at Unit for Dental Treatment of Healthy Children and Children with Special Needs, Faculty of Dentistry’ Teaching Hospital, Cairo University, in 2017 and 2018.Method: This retrospective study was approved by the Research Ethics Committee, Faculty of Dentistry, Cairo University. Data was retrieved from the files of the pediatric patients, aged from 1 to 18 years old, who received dental treatment under GA, between January 2017 to December 2018, at this Unit. Patients with special needs, with either mental or physical disability, were assigned as Group A, while the healthy patients were assigned as Group B. The two Groups were compared for: the treatment modalities of operative restorations, pulp therapy, anterior and posterior crowns, fissure sealants, dental prophylaxis, and extractions of teeth. The number of repeated admissions for dental treatment under GA was also included in the Study.Results: The total number of children who had dental treatment under GA in the years 2017 and 2018 was 2276. Number of children with SHCN was 553 (24.3%), while the number of healthy children was 1723 (75.7%). Group A showed significantly higher mean age (7.04) than Group B (4.27), (P-value <0.001). Group A showed a higher percentage of previous admissions for dental treatment under GA (13.4%), than group B (0.6%) (P-value <0.001). The most frequent disability was cerebral palsy (41.2%), followed by autism (17.7%), then mental retardation (15.2%). For primary dentition, Group A showed significantly higher prevalence of extractions for molars and incisors than Group B (P-value <0.001, effect size = 0.159 and P-value <0.001, effect size = 0.150, respectively), and higher prevalence of glass ionomer (GI) fillings for molars than Group B. Group A showed significantly lower prevalence of: composite fillings, GI fillings for incisors, pulpotomies, pulpectomies, and crowns. There was no statistically significant difference in amalgam filling treatments and fissure sealant applications between the two Groups. For permanent dentition, Group A showed significantly higher prevalence of amalgam fillings, composite fillings and crowns for molars than Group B. In addition, Group A showed significantly higher prevalence of dental prophylaxis than Group B.Conclusions: The use of radical treatment as extraction of extensive decayed teeth in children with SHCN is observed in this Study. The use of crowns to protect the teeth even without pulp therapy is demonstrable in the treatment pattern revealed in this Study. A special attention should be directed toward preventive procedures such as dental prophylaxis, fissure sealants and topical fluoride application. Education of parents/caregivers is needed to implement and supervise the proper oral hygiene measures for the children with SHCN.
