Smoking kills 900,000 people every year in India. Many studies have shown that counseling from a health professional is an effective method of helping patients quit. The aim of this study was to evaluate the knowledge and attitudes of dental students in Karnataka, India, towards smoking cessation counseling. A questionnaire study was conducted among a convenience sample of 329 dental students comprised of III year and IV year students and interns in three dental colleges in Karnataka, India. Of the 329 students who completed the questionnaire, twenty-two (7 percent) were current smokers, and fifteen (5 percent) were ex-smokers. Although 94 percent responded they were giving antismoking advice to their patients, only 47 percent said they had been taught antismoking advice suitable for patients. While a majority (95 percent) planned to advise patients about tobacco use in their professional careers, significantly fewer (66 percent) indicated that such counseling would help patients to quit. This study of dental students and interns found that a majority intended to provide smoking cessation counseling in their professional career and agreed it is part of their professional role.Dr.
Aim:The present study is aimed at delineation of different types of rugae in two different populations and developing a discriminant function for the same.Materials and Methods:A total of 940 subjects were included in the present study. The sample consisted of 466 subjects from South Indian population and 474 from North Indian population in the age group of 18-23 years. Neo colloid Easy flow(™) alginate impressions of maxillary arch were made and casts were immediately poured with Type IV dental stone. A sharp graphite pencil was used to delineate the rugae and patterns were recorded according to the classification given by Kapali et al. The association between different population and different sexes was analyzed with chi-square test and a stepwise discriminant function analysis was also performed to develop a discriminant formula.Results:Wavy, curved and straight rugae were the most common forms in both groups. Chi-square analysis for association between rugae shape and population groups showed significant differences among all the rugae patterns at the P < 5%. Chi-square analysis for assessing sex differences in the rugae shapes showed significant difference in straight, unification and circular type. Five rugae shapes – curved, wavy, nonspecific, unification and circular – were selected for discriminant function.Conclusion:The discriminant function equation obtained from the different rugae shapes in the present study was highly accurate enough to distinguish the Southern and Northern Indian population with the classification accuracy of 87.8%. Thus to identify a specific population, separate discriminant function formulae have to be developed. Hence, the study of palatal rugae is one of the simple and reliable tools for population identification in forensic science.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
