Abstract
OBJECTIVE:Todeterminetheassociationoftoothlosswith temporomandibular disorders (TMD) in in our local population.METHODS:Thiscase-controlstudywascarriedoutinDepartmentof Prosthodontics at Armed Forces Institute of Dentistry, Rawalpindi, Pakistan. A sample size of 285 subjects (95 cases and 190 controls) was enrolled in the study. Anamnestic questionnaire was administered to the patients fullling the criteria. Based on the score attained, patients were grouped as TMD patients (case) or TMD free patients (control). A pre-designed performa was used to record the data. SPSS v.17.0 was used for descriptive and inferential analysis.RESULTS: The mean age of the participants was 33.3±11.2 years with male to female ratio of with 1.26:1. Maximum of the participants (72%) were of 41 years or less. Overall mean number of missing teeth in all participants was 3.41±3.08. Mean number of missing teeth in cases and controls was 4.46±3.65 and 2.89±2.60 respectively (p< 0.001). Tooth loss of <5 teeth & ≥5 teeth was observed in 53 & 42 cases as compared to 128 & 62 controls respectively (OR=0.61; 95% CI: 0.36 to 1.01; p-vale 0.056). The relationship for number of quadrants with number of missing teeth in cases and control groups was signicant (p-value=<0.001). CONCLUSION: Present study indicates that there is signicant correlation between the numbers of quadrants with tooth loss and TMD. Increasing the number of quadrants with tooth loss will increase the risk of TMD. However, the number of teeth lost itself has no association with TMD.
