Effect of gender on the prevalence of class ii restoration in mandibular first molars-a retrospective case analysis of 86,000 cases

Abstract

Background: Dental amalgam is one of the most versatile restorative materials used in dentistry. It constitutes approximately 75% of all restorative materials used by dentists. It has served as a dental restoration for more than 165 years. There is still no adequate economic alternative for dental amalgam. The combination of reliable long-term performance in load bearing situations and low cost is unmatched by other dental restorative material. Aim: The present study aims to evaluate the association between age and gender of patients who underwent amalgam class II restoration in mandibular first molar. Materials and Method: The study sample consists of all patients between the age group 18-71 years who underwent amalgam class II restoration in mandibular first molar from june 2019-april 2020 at the SDC. The data collected were analysed for the number, age, gender for amalgam class II restoration in mandibular first molar. For a comparison between different variables, statistical package IBM SPSS 20 software analyzer was used and the statistics were obtained. Result: In this study, we can contemplate that Males(50.6%) have undergone more amalgam class II restoration in mandibular first molar when compared to females. Whereas, people of age groups 18-30 years(37%) have undergone more amalgam class II restoration in mandibular first molar. When compared to 36, more number of amalgam class II restoration was done in 46 (50.6%). There is no significant association between age, gender in patients undergoing amalgam class II restoration in mandibular first molar. Risk analysis was done. It is observed that males have higher risk when compared to females with highest confidence interval 1.490 and lowest confidence interval 0.785. (risk value-1.082, males>females) Conclusion: Within the limitations, the age group 18-30 years underwent more amalgam class II restoration in the mandibular first molar. The Male population seem to have undergone more amalgam class II restoration in the mandibular first molar and are at greater risk when compared to females.
