Resumen

 At baseline, 38 young adults participating in a split-mouth design study, received the following treatments on three approximal lesions radiographically located around the enamel-dentine junction or in the outer third of the dentin: A. Infiltration (Icon Infiltrant-DMG, Germany); B. Sealing (Prime Bond NT-Dentsply, U.S.A.); and C. Placebo treatment; all received flossing instructions. Objective: To determine after 2 years which risk indicators can better explain caries progression of these approximal lesions. Methods: The follow-up examination included 2 bite-wing radiographs for pair-wise comparison of lesions against baseline radiographs, and clinical examination of: -Papilla Bleeding Index-PBI (0; 1-4); Plaque Index-PI (0; 1-2); and new D-S. To analyze the possible association between 2-year caries progression and the presence of these risk indicators, the sample was separated into two possible scenarios, namely: Individuals with untreated lesions (C) (n=38) and Individuals with one/two treated lesions (A/B) (n=38). The Relative Risk (RR) of the risk indicators was calculated for each scenario. Results: In scenario C, 24 subjects presented lesion progression and 14 did not. In scenario A/B, 21 subjects presented progression of at least one lesion, and 17 did not. The RR in the Untreated scenario corresponded to: PBI=1.67, PI=1.50, and new D-S=1.08. Correspondent values in the Treated scenario were 0.89, 2.27, and 1.63, respectively. The calculated value of c2 for all RR corresponded to a P value >0.1, except for PI in the treated scenario (c2 = 6.65; P<0.01), indicating that those who had a plaque score greater than 0 are 2.27 times more likely to have caries progression when compared to those whose plaque index was 0 (95%CI = 1.22-4.23). Conclusion: In this study the presence of plaque was associated with caries progression within approximal treated lesions. This study was partially funded by DMG-Germany
