Aims and Objectives:The aim of the study is to assess the knowledge, attitude, and practice (KAP) of forensic odontology among undergraduate, graduate, and postgraduate dental students at Riyadh Elm University, Riyadh, Saudi Arabia.Material and Methods:This is a cross-sectional, institution-based survey study conducted among 400 dental students, which included 220 undergraduates, eighty interns, sixty graduates, and forty postgraduates aged, between 18 and 28 years. A self-administered structured questionnaire written in English and Arabic language was given to all willing student participants. Questionnaire included KAP criteria based along with demographic data. Statistical data were analyzed using Chi-square test.Results:Seventy-five percent of postgraduates, 42% of graduates, and 40.9% of the undergraduates were aware that teeth serve as a source of DNA. Ninety-five percent of the participants were aware that forensic dentistry helps to investigate criminals and dead persons. About 72% of the undergraduates and 77.5% of postgraduates were aware that forensic odontology helps in identification of deceased person's age and gender in mass disasters using dental records. About 62.73% of the undergraduates were unaware of the job opportunities in forensic dentistry in Saudi Arabia and 97.5% of the participants revealed that forensic dentistry was not included as part of the curriculum in undergraduate and postgraduate dental courses. About 93.2% of the undergraduate and 83.4% of graduate dental students agreed that they lack knowledge about forensic dentistry.Conclusion:Our study revealed inadequate knowledge, poor attitude, and lack of practice of forensic odontology among undergraduate and graduate dental students than the postgraduates.

Resorbable collagen has been utilized to treat wounds, close graft, and tooth extraction sites, and enhance recovery. Collagen-based membranes are also used as barriers in periodontal and implant therapy to limit epithelial migration and allow cells with the regenerative capacity to fill the problem area. This systematic review was carried out to analyze the studies focusing on collagen structure, synthesis, and its applications. A detailed and extensive search was performed with the help of the keywords "collagen structure", "collagen synthesis" and "collagen applications". There was extensive literature search in reliable and authentic databases like PubMed, Scopus, Web of Sciences, Ovidsp, and Cochrane library to obtain papers focusing on collagen structure, synthesis, and applications. During the systematic review, data were obtained concerning the following parameters. Type of study, nature of aim of the study, size of the sample in the study, gender and age of the subjects included in the study, prevalence of skin diseases where collagen was used for treatment, dose of collagen used, form in which collagen was used, the origin of collagen used, analysis of different variables, structure, and synthesis of collagen. Twenty-two studies were included in this systematic review. The studies discussed the structure, synthesis, and applications of collagen in treatment. In studies focusing on the application of collagen supplements, most of the study subjects were females (68.3%). The study subjects included both healthy and unhealthy subjects. The study subjects were divided into two categories. One category was the intervention group, while another group was the placebo group. Collagen was administered in hydrolysate form (90%) in some studies, bovine form (2.3%), and porcine form (3.4%) in other studies. Collagen supplementation was found to provide better results in both healthy and unhealthy effects in improving the health of skin, cornea, bone, periodontium, face, etc. It can be concluded that collagen is an integral part of the body. The application of collagen supplements can be pretty effective in maintaining the proper health of several important structures of the body like skin, face, cornea, nails, periodontium, etc. Thus, a detailed study of the molecular structure of collagen and genes associated with each type of collagen is essential for further research and treatment of collagen-associated disorders.

Introduction: With the increased stress among the students, their sleep patterns have been derailed from the routine. Hence, in our study, we aimed to appraise among the dental students the occurrence of sleep disorders. Materials and Methods: We conducted a questionnaire-based survey study among 1115 dental students of 1–4 years. The survey was based on SLEEP-50 that had 50 questions that were given scores from 1 to 4 based on the response. The scores were analyzed for the statistical connotation, keeping P < 0.05 as significant. Results: We observed that 352 students suffered from sleep disorders. The sex ratio of male:female was 25:75. No significant age variation was seen. For the various disorders, insomnia (25%), nightmares (13%), and sleepwalk (8%), circadian rhythm disorders (34%), obstructive sleep apnea (26%), and narcolepsy (30%) were noted with significant variation. The habit of alcohol was seen in 17% of students. Conclusions: The sleep disorders were prevalent among the dental students due to the great amount of stress caused in the study. They should be educated about the stress management methods and importance of sleep.
