Non-Operative Treatment of Non-Cavitated Approximal Carious Lesions of Primary Molars

Aim: To assess the clinical success rate of microinvasive caries infiltration technique with low viscosity resin in non-cavitated approximal carious lesions in primary molars after one year. Material and methods: The study included 16 children, aged 4-7 years. They were divided into two groups according to individual caries risk assessment. Twenty primary molars were with non cavitated approximal carious lesions within the enamel to the outer third of dentin (E1, E2, D1). These lesions were demonstrated and evaluated according to the depth using diagnostic bite-wing X-rays. Bite-wing radiographs were taken also at 6 and 12 months after the application for evaluation of the infiltration method. The clinical application of infiltrant (Icon Caries Proximal, DMG) was conducted according to the manufacturer`s instruction. In order to analyze the results a test of difference between two relative proportions and alternative test was used. Results The results of the study showed that the caries infiltration technique with Icon was least suitable for use in primary molars with non-cavitated approximal carious lesions in children with high caries risk.
