Background:Identification of an individual is a challenging task in the field of forensic odontology. Sometimes, the identity of individuals by fingerprints is difficult; hence, the examination of palatal rugae and the human dentition is a viable option.Aims and Objectives:The objective of the present study was to determine the sex of an individual and the hereditary pattern using three parameters are as follows: palatine rugae, dimensions of maxillary molar and maxillary canine.Materials and Methods:A cross-sectional study involved a total of 200 participants which included 60 males, 60 females and 20 families with four members each. Maxillary impressions were made with elastomeric impression material, and dental stone was used to make the models. The parameters used were as follows: palatine rugae classified by Thomas and Kotze (1983), which included the shape, size, direction and unification pattern, mesiodistal (MD) width of canines and intercanine width and MD and buccolingual width of maxillary molars.Statistical Analysis:Unpaired t-test and the median test were used to assess the sex differences in the number and unification pattern for the palatal rugae and to compare dimensions measured for males and females for the odontometric data. The data collected was statistically analyzed using the Statistical Package for Social Sciences 17.0 statistical program for windows. The statistical significance was fixed at 0.05.Results:Males showed more number of converging rugae and females showed more number of diverging patterns of rugae. The number of primary and forward rugae was more in both the genders and females showed more wavy rugae while males showed more number of straight and curved rugae. The maxillary canine and maxillary molar dimensions both were more in males than the females and also none of these parameters showed a hereditary pattern.Conclusion:Rugae pattern and the human dentition are both highly individualistic and can be used for personal identification and sex determination.
Introduction: Musculoskeletal disorders are very commonly seen in dentists. These disorders can hinder their clinical practice and at times results in severe complications leading to an early retirement. Aim: The aim of this study is to find a correlation between physical and psychological factors with the prevalence of musculoskeletal disorders in practicing dentists. This study is a culmination of two fields of medicine, physiotherapy and dentistry, thus proving to be of significant value in terms of interdisciplinary approach to healthcare. Materials and Methods: The sample size consisted of 50 dentists. It was an observational cross-sectional study with a questionnaire divided into three sections. Inclusion and exclusion criteria includes Section 1 - Demographic data and basic questions related to the aim of the study. Section 2 - Cornell Musculoskeletal Disorder Questionnaire. Section 3 - General Health Questionnaire-12 for assessment of psychological stress. Results: Wrong posture, existing physical illness, lack of exercise and increases levels of psychological stress increase the prevalence of musculoskeletal disorders. This study could be used to implement better treatment options to dentists suffering from musculoskeletal disorders considering both physical and mental factors. Conclusion: It is very important to increase the awareness of ergonomics and the influence of psychological stress in practicing dentists so that they can avoid these disorders and provide a high-quality treatment to their patients without any hindrance in their professional careers due to these disorders.
