Background: Temporomandibular disorders (TMDs) are a group of abnormalities affecting the Temporomandibular joint (TMJ), jaw muscles, or both. Pain, malocclusion, deviated mouth opening, limited jaw function, and headache are some of the most commonly noticed signs and symptoms of TMDs. Therefore, the present study was conducted to assess relationship between parafunctional habits and signs and symptoms of Temporomandibular dysfunction. Material & methods: The present study was conducted among 400 participants (15–25 years) over a period of 6 months. Data were collected using self-administered questionnaire and both intraoral and extraoralexamination. Statistical Package for Social Science (SPSS) of version 11.5 was used for statistical analysis of obtained data. P < 0.05 was considered as statistically significant. Results: In the present study Maximum (52.5%) participants had habit of nail biting followed by grinding teeth (52%). A statistically significant association was found between having harmful oral habits and three or more signs and symptoms of TMD. There was a statistically significant association between patients with TMD and three or more signs/symptoms, such as headache, noises in the TMJ, chewing difficulties and facial fatigue (P < 0.0001). Conclusion: The present study concluded that maximum participants had habit of nail biting followed by grinding teeth. A statistically significant association was found between having harmful oral habits and three or more signs and symptoms of TMD. There was a statistically significant association between patients with TMD and three or more signs/symptoms.
