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.

Dental impaction is a common problem presented by patients when seeking dental treatment. It can be described as a tooth that fails to erupt into the dental arch within an expected period of time, either partially or completely impacted. The reasons for impaction can be due to inadequate arch length and space available for eruption, excessive soft tissues or genetic abnormality. This study was conducted to evaluate the prevalence of impacted teeth among dental patients. This retrospective cross-sectional study was conducted using the patient records from a dental hospital from June 2019 until March 2020. Data regarding patients having impacted teeth were retrieved after analyzing 86000 case sheets. Radiographs and intraoral photographs were used to assess the patterns of impacted teeth. 785 patients diagnosed with impacted teeth were selected and evaluated for its prevalence based on age and gender. Excel tabulation and SPSS version 23 was used for data analysis. The statistical tests used for the demographics was frequency, percentage and for tests of association between categorical variables was Chi-square test. P value less than 0.05 was considered as statistically significant. Impacted teeth were predominantly present in males (57.5%) than in females (42.6%) among the dental patients. Mandibular left third molars showed the highest frequency of occurrence (45.7%) followed by mandibular right third molars (39.2%). Impacted teeth were predominantly present in the age group of 21-30 years (54.14%) followed by the age group of 31-40 years (23.69%) among the dental patients. Association between age and impacted third molars was statistically significant. [p value=0.003(<0.05)]. However the association between gender and impacted third molars was statistically not significant. [p value=0.136(>0.05)]. Within the limits of this study, it can be concluded that impacted teeth among dental patients were predominantly seen in the age group of 21-30 years with male predilection. Prevalence of mandibular third molar impactions was high with the left mandibular third molar being the most common impacted tooth in our study population.
