Abstract

International Journal of Paediatric Dentistry 2012; 22: 451-458 Background. Dental sealants are an effective treatment for the prevention and management of caries. Objective. To determine the retention of sealants placed in a rural setting in Mexico as part of an international service-learning (ISL) programme and to determine associations between dental sealant's retention and caries diagnosis at the time of sealant placement. Methods. Children aged 6-15 were examined for dental caries, received sealants by dental students as part of an ISL programme, and were re-examined 4, 2, or 1years after placement to assess sealant survival. Sealants were placed on permanent sound surfaces and enamel caries lesions [International Caries Assessment and Detection System (ICDAS) criteria]. Sealant survival was explored using Cochran-Mantel-Haenszel tests and multivariate prediction models. Results. 219 (46%) of 478 (mean age=10.53 SD=5.11) children who had received sealants returned for a recall examination (mean age=10.89 SD=3.11). After 1-4years, 96.4% to 60.6% of the sealants placed on sound teeth had survived, and for sealants placed on surfaces with enamel caries lesions (ICDAS 1-3), 94.2% to 55.6% had survived. Differences were not statistically significant. Conclusions. Sealants had survival rates comparable to those previously reported in the literature. Sealants placed on sound and enamel caries lesions had similar survival rates.
