Abstract

Background: In this study, masticatory efficiency of patients with unilateral missing mandibular 1st molar were evaluated pre and post rehabilitation with three unit fixed partial denture prosthesis. Six male and four female patients within the age range of 17-35 years and who had no cranio-mandibular disorder, any obvious malocclusion, or extensive restoration were included. Evaluation of masticatory efficiency was done by spectrophotometry and raw carrot was used as test material. To see the difference, among the groups, pre and post rehabilitation Masticatory efficiency was tested using spectrophotometer once again on experimental side and control side were recorded. Paired samples t-test was applied for statistical data analysis.

Result: The mean and standard deviation of masticatory efficiency for pre and post rehabilitation changes on experimental side was 0.694±0. 749; 0.885±0.752 and for control side was 0.884±0.698; 0.994±0.675 respectively. The difference between the two groups was statistically significant at p<0.01 levels.

Conclusion: Masticatory efficiency were decreased on experimental (missing mandibular 1st molar) side as compared to the control side (intact dentition) before rehabilitation. Post rehabilitation, there was an increase Masticatory Efficiency in all the Patients.
