Objective: This study aimed to evaluate the intraoral caries activity of removable partial denture wearing patients with the use of Cocos nucifera oil as an adjuvant to routine oral hygiene measures. Materials and methods: Removable partial dentures were done for 63 patients and caries assessment was done for the remaining natural teeth which were used as the abutments for serving the purpose of retention and also for the non-abutment teeth. International Caries Detection and Assessment System (ICDAS) criteria of caries assessment was done following the regular use of C. nucifera oil. Standard protocols were followed, and revisits were carried out every 6 months duration for 36 months for assessment of the progression of caries activity. Qualified dental personnel examined the denture wearers for the entire study period. Results: Clinical evaluations were done after the restoration of the partially edentulous patients for an average of 6 months with the use of C. nucifera oil. About 82% of the teeth made had no noticeable difference in the caries activity status and 57% of the sample were without any signs of active caries activity. Results indicate that there was no loss of both the abutment and non-abutment teeth due to caries activity during the observation period, ensuring a 91% caries protection rate. Conclusion: C. nucifera oil exhibits caries protective activity and satisfactory survival rate without any loss of remaining natural teeth among removable partial denture wearing patients during the 36 months observation period.
