Introduction: Temporomandibular disorder (TMD) is a group of condition affecting the temporomandibular joint, masticatory muscles, and the adjacent structures. The etiology of TMD in children and adolescents is considered multifactorial in nature and has been related to trauma, malocclusion, and parafunctional habits. Aim: The aim of this study is to find whether harmful oral habits are associated with sign and symptoms of TMD among adolescents in Wardha district. Materials and Methods: A short-span study was conducted in Wardha, Maharashtra. A self-administered based study was done among 200 adolescents which comprised of 107 females and 93 males. Data were collected using self-administered questionnaire and clinical oral examination that was conducted. The questionnaire was consist of knowledge responses (yes/no) and attitude responses (never, rarely, sometimes, often, and always). Chi-square test was used to perform statistical analysis and level of significance was set at P < 0.05. Results: The main method used was self-administered questionnaires with sample characteristics of 53.5% female and 46.5% male. Population was divided into two age groups. Total number of adolescents in age Group 1 (9–14 years) was 85 and age Group 2 (15–19 years) was 115. Seventy-seven (38.5%) adolescent reported no sign and symptoms of TMD and rest of them reported yes to at least one statement of questionnaire. Bruxism (67%) was the most frequently observed habit whereas chewing gums (5%) as the least observed habit. Statistically significant gender difference was not observed in the questionnaire. Higher frequency of TMD symptoms was reported in the age group of 15–19 years. Sixteen (8%) subjects reported nonparafunctional habits whereas 184 (92%) subjects had parafunctional habits. During clinical examination, muscle sensitivity to palpation was most frequent sign in the age of group 15–19 years with P = 0.023. Higher severity was reported are morning facial pain, pain while chewing, clicking sound, and using one side while chewing. Conclusion: Result shows that there was no association between parafunctional habits and signs and symptom of TMD. In age group of 15–19 years, it was statistically significant. Hence, while treating patient dentist should give attention to parafunctional habits in this age group especially.
