Impaction of the third molars has been established as a factor with the potential to damage temporomandibular joints. Furthermore, the trauma resulting from the surgery of third molars has been reported to be a predisposing factor in the progression of temporomandibular joint disorders (TMD) symptoms. The high frequency of third molar surgery can result in an increased number of patients who suffer from chronic oral and facial pains. Thus, it is important to identify those patients who have pre‐existing pain or any signs of dysfunction in their temporomandibular joints and masticatory structures, prior to third molar surgery. The aim of this study was to evaluate the association between impacted teeth and temporomandibular joint disorders. A retrospective study was conducted by reviewing the case records of patients who underwent treatment in Saveetha Dental College and Hospital from June 2019 - March 2020. The study population included 96 patients diagnosed with temporomandibular joint disorders and 98 patients without TMD. Thus the sample size included a total of 194 patients who were evaluated for the presence of impacted teeth. Data was collected and statistical analysis was performed. Microsoft Excel 2016 (Microsoft office 10) data spreadsheet was used to collect data and later exported to SPSS IBM (version 23.0). Descriptive statistics and chi square test were employed with a level of significance set at p<0.05. The most prevalent age group among the patients was 21 - 30 years (34.39%), followed by 31 - 40 years (29.29%). 60.8% were male patients and 39.2% were females. TMD was predominantly present (29.38%) in patients with impacted teeth than in patients without impacted teeth (20.1%) and the results were statistically significant (p=0.003). Within the limits of this study, there is a significant association between the presence of impacted teeth and temporomandibular joint disorders. Therefore, it is important to include an assessment of the temporomandibular apparatus in the pre‐operative evaluation of patients with impacted third molars.
