Objectives: The facial characteristics of Egyptian children were examined using Steiner analysis. Material and Methods: Sixty children were included in the study (40 girls and 20 boys). The selection criteria were: all in mixed dentition stage (mean age: 9.27 ± 1.57 years), acceptable profile, absence of craniofacial deformities, normal overjet and overbite and no crossbite. This retrospective study was chosen to avoid unnecessary radiation exposure. All children had previously undergone cephalometric analysis for follow up and supervision at 6 month intervals. Sixteen cephalometric measurements according to Steiner analysis were recorded and analyzed statistically. Results: The most pronounced changes between girls and boys were Sn-GoGn which was steeper in girls and SL (the length of the anterior cranial base) which was larger in boys than girls. Conclusion: No significant difference was found between boys and girls except for the above measurements, the measurements values of this research can be used as cephalometric standards for Egyptian children in the mixed dentition period.

Objectives: To assess the capability of different orthodontic arch-wires to retain oral biofilm and to correlate the adhesion to surface roughness of the wires. Methods: Four types of orthodontic arch- wires were used for the study, Nickel-titanium (NiTi), Copper nickel-titanium (Cu-NiTi) , Beta Titanium (TMA ) & Beta III Titanium (CNA) new arch wires and 4 weeks after intraoral usage, were examined for Surface roughness (SR) using an atomic force microscope (AFM). Adhesion of Streptococcus mutans (MS), Staphylococcus aureus (SA), and Candida albicans (CA) were performed using colony count method. Statistically, the following tests were done: analysis of variance, Pearson correlation coefficient test, post hoc Tukey test. Results: The four wire types showed significant increases in SR (P˂ 0.05) after 4 weeks of intra-oral usage, TMA wires recorded the highest roughness values while the lowest ones were for NiTi wires. Bacterial adhesion was detected on all wires, ANOVA showed significant differences between the wires concerning MS, SA and CA adhesion. A significant positive correlation (P=.001) was observed between bacterial adhesion and surface roughness after intra-oral exposure. Conclusions: SR of the wires increased after intra-oral use and there was a positive correlation with the biofilm adhesion.

Background: Good oral health is essential for the overall health and well-being of a child and is one of the important factors for a disease-free life. .Objective: The objective of this study was to evaluate oral health awareness among Egyptian parents and its relationship with the dental health status of their children. Subjects and methods: one hundred and ten children aged 6–12 years selected from outpatients visiting the public dental clinic of October 6 university hospital ,were included in the study. A comprehensive questionnaire with apparent validity was designed enclosing questions regarding views of parents on oral health knowledge for their children, caries prevention and role of diet, which was distributed to the parents .Results: There was no statistically significant difference between DMFT and deft scores in children with the unsatisfactory and satisfactory awareness levels of their parents. DMFT showed positive significant correlation with age and total parental questionnaire score. On the other hand, there was a statistically significant inverse correlation between age and deft , also deft showed negative insignificant correlation with total parental questionnaire score. Finally, there was a statistically significant inverse correlation between DMFT and deft. Conclusion: Parents' knowledge and awareness of oral health were poor among Egyptian parents. Special attention should be directed to parents with low socioeconomic status who need to be more educated about oral health of their children

Objective: determine the changes of alveolar bone level following intrusion and extrusion orthodontic movement of mandibular incisors.M & M: 20 patients divided into 2 groups; (I): extrusion group (II): intrusion group pretreatment and post-treatment CBCT & measurements of alveolar bone level in all aspects of the mandibular incisors by Mimics software. The obtained data were statistically analyzed.Results: In group (I), the mandibular lateral incisors showed greater but still statistically non-significant (P >0.05) alveolar bone loss than mandibular central incisors. The lingual aspect of the mandibular lateral incisors showed greater and statistically significant loss (P < 0.05) than the same aspect of the mandibular central incisor (0.70 + 0.13-0.60 + 0.14 respectively). In group (II), there were non-significant alveolar bone changes between mandibular central and lateral incisors. Comparison between the combined sites between group (I) and (II) revealed that, there was a significant greater loss (P < 0.05) in the mesial side of the central incisors in extrusion group than in intrusion group (1.26 + 0.29-1.12 + 0.12 respectively), while a more significant loss in the buccal and lingual side of central incisors in group (II) than group (I). The decrease of the alveolar bone level of lower lateral incisors was significantly greater in the distal side of extrusion group than intrusion group.Conclusions: The mandibular lateral incisors when compared with mandibular central incisors showed a greater amount of bone loss particularly the lingual aspect. Greater bone loss of the buccal and lingual aspects of mandibular incisors in group(II) than in group(I)

Abstract: <br /> Objective: To evaluate and compare the remineralization effect of casein phospho-peptide amorphous calcium phosphate with or without fluoride “MI paste”&“MI Paste Plus” respectively” on the re-mineralization of enamel caries-like lesions in primary teeth.<br /> Material and methods: Artificial caries lesion was made on the labial surface of 40 extracted or exfoliated sound primary teeth which were then divided into 2 halves; one half was treated with one of the tested remineralizing agent “MI paste” or “MI Paste Plus”” while the other half served as a control. The lesions were evaluated both qualitatively using a polarized light microscope and quantitatively by measuring “calcium and phosphate” content using “energy-dispersive X-ray spectroscopy”. Data were collected and analyzed by using paired t-test to compare the control and the study groups for each material, while the “t-test” was used to compare between the two study groups.<br /> Results: Both “MI paste” and “MI Paste Plus” showed significant re-mineralization to the subsurface enamel lesions. “MI Paste Plus” showed significantly better results than “MI paste” with an increased amount of calcium “t=5.59 p=<0.0001”, Ca/phosphate ratio “t=4.08 p=0.003” and reduction in the amount of phosphate content “t=4.57 p= 0.001”.<br /> Conclusion: Both “MI paste” and “MI Paste Plus” were effective in enamel remineralization, the addition of fluoride in “MI Paste Plus” acted synergistically with the casein phospho-peptide amorphous calcium phosphate and gave better remineralization effect on enamel.

Background: Salvia officinalis (S. officinalis) has been vastly used in medicine as it possesses anticaries, antiplaque, anti-inflammatory, antibacterial, antifungal, antiviral, astringent, antioxidant effects. Aim: This study was executed to estimate the antibacterial effect of glass ionomer cement (GIC) containing S. officinalis on Streptococcus mutans (S. mutans) as main etiological factor of dental caries process. Methods: A total number of 12 specimens were assigned into 2 equal groups: Group 1(Control group) where conventional powder and liquid Fuji IX GIC was used and Group 2 (Test group) where the S. officinalis extract was prepared and added to the GIC liquid at 0.5% weight concentration level. Six disk shaped specimens, with diameter 10 mm and thickness 2 mm, were constructed for each group then tested, in vitro, against strains of S. mutans. Diameter of inhibition zone was recorded after 24 and 48 h. Results: During the study period, the mean diameter of the inhibition zones was high in the test group in contrast to the control group, with high statistically significant difference. Conclusions: Glass ionomer cement with S. officinalis extract has direct inhibitory effect towards S. mutans.

Purpose: A case control study was performed to investigate the effect of silver diamine fluoride (SDF) and potassium iodide (KI) [Riva Star, SDI] on the microtensile bond strength between glass ionomer cement and carious primary dentin and to evaluate the mode of restoration failure. Methods: Forty carious primary molars were sectioned into halves through the carious lesions and randomly allocated to test and control groups. The test specimens were treated with SDFand KI with concentration of 0.06 gm/ml fluoride ions and the control specimens with deionized water. The samples were stored in artificial saliva for 14 days in normal room temprature, and the dentin surfaces were conditioned and restored with Fuji IX GP Extra. After 24 hours in artificial saliva, the specimens were prepared for microtensile bond strength testing and stressed with tension at 1 mm / minute until failure. Mean bond strengths were compared using the paired t test and the failure mode was recorded. Results: The mean microtensile strength for the test group was 7.4 MPa (±5.1 SD) and 6.3 (±4.6) for the control group (P>0.05). Most common failure mode was the mixed failure in both groups. Conclusion: Silver diamine fluoride and potassium iodide does not adversely affect the bond strength between glass ionomer cement and carious primary dentin in vitro.
