Efficacy of fluoride gel in arresting active non-cavitated caries lesions: a randomized clinical trial.

This study evaluated the efficacy of fluoride gel in arresting active non-cavitated caries lesions in permanent teeth. This randomized, triple-blind, placebo-controlled clinical trial randomized 100 schoolchildren aged 10.7 ± 2.

Radiographic pattern of inactive occlusal enamel lesions and its relationship with caries progression over 4-5 years.

Objective: To assess the radiographic pattern of inactive enamel caries lesions (IECL) in the occlusal surfaces of permanent molars and to investigate whether the presence of radiolucency at baseline could predict lesion progression over 4-5 years.

Methods: A prospective cohort study followed 193 schoolchildren from southern Brazil. At baseline, clinical and radiographic examinations were performed.
