Prevalence of Temporomandibular Disorders among Partially Edentulous Patients: A Hospital Based Cross-Sectional Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 4
Abstract
Aim: The purpose of this study is to investigateprevalence of temporomandibular disorders (TMD) among partially edentulous patients. Background: The prevalence of TMD signs in partially edentulous patients has not been well‑ documented. On the contrary, much of the published work has been attributed to the complete denturewearing and the dentate patients. Methods: A total of 150 samples with Kennedy Class I or Class II partially edentulousarch, with age group range 30to75 were selected. The evaluation of TMD was done usingHelkimo index. The results were analysed by Frequency distribution and Chi –square test. Result: On evaluation of signs of TMD, the Frequency distribution ofclinical dysfunction index (Di) showed that 60.7% of the samples were free of anysigns and the Frequency distribution of anamnestic index (Ai), based on subjective findings shows that 66.7% of the samples were free of any symptoms. On evaluating different signs of TMD,84% of the population had normal range of movement (≥ 40mm), 69.3% had smooth movements without temporomandibular joint(TMJ) sounds or deviation in both opening and closing movements ≤ 2mm, 98% did not have tenderness to palpation in masticatory muscles, 96% did not have tenderness to palpation in TMJ region and 86.7% did not have pain on movement of mandible. There was statistically significant difference between male and female subjects (p=0.017) and no significant difference among different age groups. When comparing Kennedy Class I and Class II edentulous subjects, Class I maxilla group subjects were least affected. Conclusion: There is a low prevalence of the signs and symptoms of TMD among subjects who were included in this study. As TMD is a multifactorial condition, none of the literature shows a standardized protocol for the assessment and treatment and the results given were inconsistent. Thus more research is required in this field.
