Abstract

Objective: Considering the minimally invasive approach to dentistry, the scientific community has focused on non-invasive treatments for caries lesions. The aim of this study was to evaluate the efficacy of a nonsurgical approach to arrest occlusal non-cavitated dentin lesions through glass ionomer sealing.

Methods: In this controlled clinical trial, 51 teeth with clinically non-cavitated occlusal caries radiographically located beneath the enamel-dentine junction (radiolucent area) were selected among patients presenting a moderate to high risk of caries. The teeth were randomly divided into two groups: an experimental group receiving an application of Vidrion-R (SS White) glass ionomer and a control group not submitted to any clinical intervention. Caries progression was monitored by clinical and radiographic examination at 4-monthly intervals over a period of one year. In addition, marginal integrity of the sealant was evaluated in the experimental group.

Results: Clinical examination showed no statistical difference between the groups (P=.13). On the other hand, sealed teeth presented lower caries progression when analyzed by radiographic examination (P=.004).

Conclusion: A glass ionomer sealant over non-cavitated occlusal caries lesions in dentin may not be sufficiently effective in arresting their progression.

Keywords: Pit and fissure sealant; caries; clinical trial; dentin; glass ionomer cement.
