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.


To compare the efficacy of a traditional fissure sealant in managing NCDOL in primary molars.


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.


The two treatment modalities were found to be similarly effective in managing DONCL in primary molars.


For the management of non-cavitated dentin occlusal caries in primary teeth, the invasive approach can be replaced with non-drilling fissure sealing techniques.
