Background:Like in any other profession, dental surgeons are also afflicted by many occupational health hazards such as Musculoskeletal disorders (MSD) and mental health related issues.Aims:To assess the distribution of MSD and mental health related issues amidst dentists in Salem City according to age, sex and number of working hours per week.Objectives:A survey was organized to check the rate of occurrence of these occupational health hazards among dental practitioners in Salem city.Materials and Methods:The study was conducted among one hundred and fifty dentists practicing in Salem City in the form of questionnaire. Dentists were asked about any occupational disease that they suffered related to a musculo–skeletal pain and its location whether in the back, upper limbs or lower limbs. In addition to this, dentists were asked about mental stress that they had experienced.Results:MSD showed higher rate of prevalence compared to mental health related issues.Conclusion:The application of preventive measures is necessary, in view of the high rate of these disorders in the society of dental practitioners.

Aim: This study aimed to analyze incidence of isthmus in human permanent mandibular first molar teeth using cone-beam computed tomographic imaging techniques in a South Indian population. Materials and Methods: Three hundred permanent mandibular first molar teeth were collected, cleaned, and stored in normal saline. They were divided into groups (GPs) I and II based on number of roots, and were further subdivided (right and left [RL] subgroups A and B for GP I; and RL subgroups C and D for GP-II). Samples were processed and isthmus incidence was evaluated by cone-beam tomography, compared, and statistically analyzed. Results: Overall in mandibular first molars, the isthmus incidence in mesial root was 97.2%, distal root was 39%, and distolingual root was 0%. There was no statistically significant difference between the right and left mandibular first molar teeth with regard to incidence of isthmus ( P > 0.05). There was an incidence of type I (38.67%), type II (56.33%), type III (3%), and type IV (2%) isthmuses in mesial root and type I (12.33%), type II (16%), and type III (10.67%) in distal root. Conclusion: Incidence of isthmus was very high in the mesial root of the mandibular first molar and should be factored during nonsurgical and surgical endodontic treatment procedures to achieve successful treatment outcomes.

Background: Similar to several other occupations, dentists are also stricken by bounteous occupational health hazards (OHHs) such as musculoskeletal disorders (MSDs) and ocular health–related issues. Aims: The aim of this study was to evaluate the diffusion of MSDs and ocular health–related issues among dental surgeons in Salem city, Tamil Nadu, India, according to age, sex, and number of practicing hours per week. Objectives: A survey was conducted to examine the rate of prevalence of these OHHs amidst the dental surgeons in Salem city. Materials and Methods: The study was performed through a questionnaire amidst 150 dentists practicing in Salem City, Tamil Nadu, India. Dental surgeons were questioned about any occupational disorder that they had experienced related to a musculoskeletal pain and its location whether in the back, upper limbs, or lower limbs. In extension to this, dental surgeons were asked about any ocular injury that they had. Results: MSD showed higher rate of occurrence correlated to ocular health–related issues. Conclusion: The practice of protective measures is crucial, in perspective of the high rate of these disorders in the community of dental surgeons.
