Progression of Active Microcavitated Carious Lesions on Primary Molar Occlusal Surfaces

Progression of Active Microcavitated Carious Lesions on Primary Teeth Occlusal Surfaces: Randomize Clinical Trial

Objective: To verify the progression of active microcavitated carious lesions on occlusal surfaces of primary molars after the orientation of the brushing technique associated with fluoride dentifrice compared to resin sealant, through a 12-month randomized clinical trial. Methodology: We selected 22 children from 4 to 9 years old from the public school system of the city of Juazeiro do Norte-Ceará, with at least one primary molar presenting an active caries lesion score 3 of the International Caries Detection and Assessment System (ICDAS). Randomization was performed en bloc and stratified by two conditions (age and caries experience). The selected teeth were divided into two groups: the first (G1) was submitted to brushing with fluoridated toothpaste; and the other group (G2) to the resin sealing technique, whose application of the material was performed under absolute or relative isolation, selected through a second randomization. The molars undergoing treatment were evaluated at 6- and 12-month returns. Caries progression was evaluated according to the type of treatment, dental group and sealant retention by the Chi-square test. For cost analysis, the variance test (ANOVA) was used.

Inclusion Criteria:

• At least one primary molar with active caries lesions classified as ICDAS score 3.

Exclusion Criteria:

• Children with differentiated management needs and/or systemic diseases with oral involvement.
• Primary molar with active caries lesions classified as ICDAS score 3 that had other caries lesions involving dentin, restorations, sealants, or other types of formation defects.
