RESUMO
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.
RESUMO
BACKGROUND AND AIM: Making a diagnosis and prescribing medicine is the most important skill required by any doctor in the colleges, hospitals or clinical practice. Prescribing is the intervention that has the greatest influence on patients' health requiring complex series of sub-competencies like making a diagnosis, setting a therapeutic goal, choosing the approach, choosing the best drug, route and frequency of administration, duration of therapy, writing the prescription, patient information, monitoring drug effects and, lastly, review the prescription.The aim of this research is to assess the knowledge and practices of Indian dental students regarding the prescription of antibiotics and analgesics. METHODS: A cross-sectional study was conducted among 870 Undergraduate and Post-graduate dental students of Udaipur city. A close ended, pretested questionnaire was administered to students. The data were analyzed using the student's t -test and one-way ANOVA with post hoc Bonferroni test. RESULTS: A total of 870 students participated in the study. Most of them were females and were pursuing undergraduate studies. Post graduate students had greater medication prescription knowledge than the undergraduate students. Nevertheless, practice of medication prescription among these two was found adequate. CONCLUSION: Undergraduate dental students have lower knowledge about medication prescription as compared to post-graduate students. Also, knowledge of prescription of medicines in males were higher in comparison to females, though prescription practices of all the dental students was found almost similar.
RESUMO
INTRODUCTION: In the event of any mass fatality incident, DNA analysis plays a vital role in disaster victim identification. Teeth are one of the most resistant structures in the human body that resist decomposition hence making them prime choice for extracting DNA for identification of individuals. Polymerase Chain Reaction (PCR) analysis that target regions of Amelogenin gene have become the method of choice for sex determination of biological samples. AIM: Determining the sex of a given DNA sample from either dental pulp or dentin of tooth and help in identification of missing persons and disaster victims. MATERIALS AND METHODS: In our study 50 teeth samples were studied and they were subjected to various environmental conditions along with freshly extracted teeth taken as control for duration of one month and three months. Pulpal tissue was retrieved from the teeth specimens by access opening of root canals and for incinerated samples, the specimens were crushed. From the DNA that was extracted from the dental pulp sample Amelogenin gene locus was used for sex determination by amplifying a segment of X-Y homologous gene locus through PCR analysis. RESULTS: ANOVA test and t-test proved to be statistically significant and 100% retrieval rate was observed in samples. CONCLUSION: Pulpal tissue along with degenerating odontoblastic processes yield sufficient amount of DNA for gender determination when subjected to various forensic conditions with maximum accuracy.
