Assessment of the Success Rate of Conservative Adhesive Resin Restoration (CAR) in First Permanent Molar Teeth Treatment in Hamadan, Iran

Abstract

Background & aim: Dental caries is one of the most common childhood diseases in the world. Pit and fissure caries constitute more than 80% of all caries in children and adolescents. Although occlusal surfaces account for only 12.5% of tooth surfaces, approximately 60% of dental caries are observed in these surfaces. Caries preventive methods include fluoride therapy, fissure sealant, and conservative adhesive restoration (CAR). Although CAR method has been increasingly applied for the prevention of dental caries progression, little research has been conducted so far. Despite the advantages of CAR method, this technique is time-consuming and uneconomical for the patient and health care system. In this study, we aimed to assess the one year success rate of CAR in caries prevention at Hamadan Dental School, Hamadan, Iran. Methods & Patients: In this cross-sectional study, the estimated sample size was 150 treated first permanent molar teeth. We examined variables such as CAR success or failure (retention and caries prevention), need for re-treatment, frequency of tooth brushing, previous history of fluoride therapy, Decayed-Missing-Filled Permanent Teeth (DMFT) index, decayed-missing filled deciduous teeth (dmft) index, dental visit, and current dental treatment. Data were analyzed using SPSS version 16. Results: Fifty-seven patients were examined, among whom 24 (42%) were male and 33 were female (58 %). The age range of the subjects was 7-13 years. A total of 125 molar teeth were studied, of which 88 (70.4%) and 37 (29.6%) belonged to female and male subjects, respectively. According to the results, the association between CAR and the patient’s age was significant (P˂0.05); also, there was a significant difference in using fluoride and CAR success (P=0.001). Conclusion: There is a significant association between the patient’s age, use of fluoride mouth rinse, and treatment success rate. In addition, older cases showed better response to CAR.
