Efficacy of a non-drilling approach to manage non-cavitated dentin occlusal caries in primary molars: a 12-month randomized controlled clinical trial

Background. Despite the efficacy of non-drilling approaches to manage non-cavitated dentin occlusal lesions ( NCDOL) in permanent teeth, there is no data validating this type of therapy in the primary dentition. Aim. To compare the efficacy of a traditional fissure sealant in managing NCDOL in primary molars. Design. This study is a randomized controlled clinical trial with a split-mouth design. Thirty schoolchildren with two NCDOL were selected and divided into two groups. The experimental group received a resin-based fissure sealant, whereas the control group was treated with a conventional composite resin. Treatment efficacy was evaluated after 1 year by means of clinical and radiographic examinations. Results. The two treatment modalities were found to be similarly effective in managing DONCL in primary molars. Conclusion. For the management of non-cavitated dentin occlusal caries in primary teeth, the invasive approach can be replaced with non-drilling fissure sealing techniques.
