Association of age and sex of patients undergoing class 2 amalgam restoration in mandibular premolars

Abstract

The most versatile restorative materials in the field of dentistry are dental amalgam which constitutes 75% of all restorative materials used by dental practitioners. Due to its excellent load-bearing capacity and low costs, it is still the top priority for many dentists.  In this retrospective study, the details of the 86,000 patient records were reviewed and analyzed, out of which 160 patients who had undergone class 2 amalgam restoration in mandibular premolars between June 2019 to March 2020 were included in this study. The details like age, gender, tooth number and the surface of restorations were evaluated and entered in SPSS, version 23. The data were analyzed through a chi-square test. It was observed that there is no significant association between age, and surface distribution in mandibular premolars (p>0.05), however, on analyzing the association between gender and tooth surface, the statistical significance between gender and tooth surface was found ( p <0.05). Within the limitations, the mandibular second premolars had undergone more class 2 amalgam restoration than the first premolar. Disto occlusal restoration was performed in higher numbers, followed by mesio occlusal restoration in both genders.
