title: Caries activity and the presence of adjacent caries lesions on resin composite restorations in primary teeth.
abstract: OBJECTIVE
  To clinically evaluate the status of caries lesions adjacent to restorations (AdjCL) in primary molars, and its relationship to the child's carious activity and marginal restoration integrity.
  
  
  METHODS
  Three independent examiners (trained, calibrated and blinded) evaluated 64 randomly selected restorations (occlusal and occluso-proximal) by the AdjCL status (kappa = 0.844), the restoration marginal integrity (kappa = 1) and the radiographic presence of lesions in the occlusal restoration margins (kappa = 1). One of the examiners also evaluated the child's carious activity (kappa = 1). The variables were related to the outcome through Chi-square and Fisher's Exact analysis (alpha = 5%).
  
  
  RESULTS
  A prevalence of 40.63% AdjCL (88.46% inactive) was seen, with no significant association to the child's carious activity (P = 0.23). The association of the absence of AdjCL and the presence of marginal integrity was statistically significant (P = 0.013). Also, the presence of AdjCL occurred especially around older restorations (P = 0.044).
