Background: Dental caries is recognised to be the most prevalent infectious disease globally. It affects all age groups and most commonly children between 6-12 year old involving both primary and permanent teeth. Apart from conventional measures for the management of dental caries, preventive measures involving sealing of the cavitated and non cavitated pits and fissures can be a feasible method for cost-effectiveness in the prevention of caries. Among the newer techniques with a long-term success rate for preventing caries are preventive resin restoration (PRR). Aim: This study aims to evaluate the most commonly treated mandibular teeth with preventive resin restoration in children with mixed dentition. Materials and Methods: This retrospective study was conducted in a university setting. Data were collected from 980 children between the ages of 6-12years who underwent preventive resin restoration for primary or permanent teeth have been included in the study. The extracted data was tabulated in a spreadsheet (Excel 2017: Microsoft Office) and analysed using SPSS 23 version software (SPSS, Inc., Chicago). Descriptive statistics and chi-square tests were performed with the level of significance at 5% (P<0.05). Results: Most PRR was done in 6 years old male patients 14.88% followed by 10 years 10.23% and 8 years 9.30% female patients respectively. Both permanent mandibular first molars are highly treated with PRR in which permanent left mandibular first molar is more commonly treated for males 16.28% than females 15.35% and permanent right mandibular first molar is more commonly treated for females 16.28% than males 10.70% This was found to be a statistically significant (P value = 0.029).
Conclusion:Within the limitations of our study it can be concluded that, preventive resin restoration is more commonly used for permanent right and left first molar region for caries prevention in both primary and permanent teeth in children between 6 -12 years of age.
