There is still great divergence in the aspects related to caries lesions around restorations. The methods and the systems used for the detection of secondary caries lesions have presented low validity. Also, the consequent treatment decisions of this kind of lesions have presented a lot of variation. However, the correct diagnosis of secondary caries may guarantee greater longevity to the restorative treatment, as well as oral health to the patients, reducing the cost and clinical time of the dentists. Therefore, the investigators aimed to perform this study to evaluate and compare two visual criteria for the evaluation of restorations in primary teeth in medium and long term outcomes for the patients, through a randomized clinical study. These criteria are the system proposed by the World Dental Federation (FDI) and the International Caries Classification and Management System - ICCMS.
