BackgroundTo measure the effectiveness of procedural video compared to live demonstration in transferring skills for fabricating orthodontic Adam’s Clasp.Materials and MethodsForty-nine fourth-year undergraduate male dental students were randomly assigned to two groups. The students in group A (n = 26) attended a live demonstration performed by one faculty, while students in group B (n = 23) watched a procedural video. Both the procedural video and live demonstration described identical steps involved in fabricating the Adam’s Clasp. Students in both groups were asked to fabricate an Adam’s Clasp in addition to completing a questionnaire, to measure their perceptions and satisfaction with the two teaching methods and lab exercise. Blind assessment was performed by one faculty for both groups.ResultsThe mean students’ scores in the fabrication of the Adam’s clasp were 6.69 and 6.78 for the live demonstration (group A) and the procedural video (group B), respectively. No significant difference was detected between the two groups (P = 0.864). Statistically significant difference was found in the mean response between the two groups for statement 6 on the questionnaire, “The steps in the teaching method were presented in a clear fashion and were easy to understand”. A higher mean response for group B was found compared to group A (P = 0.049). No significant differences were found between the two groups for the other statements (P > 0.05).ConclusionProcedural video is equally as effective as a live demonstration. Both methods should be considered in teaching undergraduate orthodontic courses in order to improve the learning experience and to match different learning preferences of students.

The aim of this study was to examine the prevalence and relationship between periodontal disease and preterm low birth weight (PLBW) among Saudi mothers at King Khalid University Hospital (KKUH) in Riyadh, Saudi Arabia. The periodontal status and the relative risk were also analyzed. The study consisted of 30 cases [infants <37 weeks and/or weighing ≥2.500 kilograms (kg)] and a daily random sample of 60 controls [≥ 37 weeks and/or weighing >2.500 kg]. Clinical periodontal indices were measured on the labor wards. Associated risk factors for periodontal disease and PLBW were ascertained by means of a structured questionnaire and maternal notes. The prevalence of the PLBW was found to be 11.3%, and the prevalence of periodontal disease was high among the study population. The risk of PLBW remained high with increasing periodontal disease (odds ratio [OR] 4.21, 95% confident interval [CI] 1.99-8.93) despite controlling the other risk factors such as age, smoking, and social class. In conclusion, there is a correlation between periodontal disease and PLBW in KKUH.

There is some evidence to a plausible association between periodontal disease and OSA. Evidence on the efficacy of periodontal disease interventions is insufficient. The causal-effect relationship of periodontal disease and OSA is debatable. Further research with case-control studies is warranted.

The purpose of this systematic review and meta-analysis was to compare the efficacy of computer-assisted learning (CAL) with traditional methods of learning in orthodontic education. Comprehensive electronic and manual searches of randomized controlled trials and prospective studies were conducted. Participants considered were undergraduate or postgraduate orthodontic students or orthodontic educators. The main outcome measure of CAL efficacy was knowledge gain. The time efficiency of the method was assessed based on the time spent learning the material, while its qualitative effect was tested by the attitudes of participants. Nine studies assessing CAL in teaching orthodontic diagnosis and treatment planning met the inclusion criteria. A statistically significantly higher knowledge gain favoring CAL was identified in studies that used pre-and post-intervention tests (weighted mean difference [WMD] 9.78 percent, 95 percent confidence intervals [CI] 2.89 percent, 16.67 percent; test of heterogeneity p=0.25). For studies that used only post-intervention tests, significantly greater efficacy was noted, but the effect size was smaller (WMD 3.79 percent, 95 percent CI 0.31 percent, 7.28 percent; test of heterogeneity p=0.003). Overall, student attitudes were positive towards CAL. No conclusions can be drawn about the time efficiency of CAL. Further studies are warranted to examine other important outcomes, including CAL efficacy in teaching other orthodontic topics, cost-effectiveness, and knowledge retention.

In the sample studied, after initially worsening, compliance with OHI improved at 5 months after bonding. Adolescents with married parents and those reporting good academic performance in school were found more likely to have complied with OHI provided at baseline and to perform better OH.

Objectives To investigate the association between unilateral/bilateral maxillary canine impaction and sella-turcica bridging using CBCT imaging. Methods This retrospective comparative study analyzed 76 CBCT images of the craniofacial complex including sella-turcica. The impacted cuspid group consisted of thirty-eight subjects (7 males, 31 females; mean age, 14.6 ± 3.2 years) diagnosed with unilateral (left n = 14, right n = 11) or bilateral (n = 13) palatal canine impaction. The control group included thirty-eight subjects matched by sex (7 males, 31 females; mean age, 19.5 ± 3.6 years) with no impaction. Multinomial logistic regression analysis was used to determine the association between unilateral/bilateral canine impaction and right and left sella-turcica bridging. Results The prevalence of sella-turcica bridging was 59.3% and 50% in the impacted canine and control groups, respectively. Although the odds for unilateral canine impaction were increased in the right and left sella-turcica bridging groups compared to the controls, the difference was not statistically significant. The risk of bilateral impaction was different between the two sides of sella-turcica bridging, but, again, the findings were not statistically significant. Conclusion Contrary to previous 2D studies, there is no statistically significant association between unilateral/bilateral palatal canine impaction and sella-turcica bridging when using 3D CBCT.
