Abstract
Aim: To compare the retention of glass ionomer cement (GIC) used as fissure sealant with a resinbased sealant. Methods: Six- to nine-year-old children (n=96) with all permanent first molars in occlusion were examined and assigned to two groups: GIC sealant or resin-based sealant. The sealants were applied according to the manufacturers’ recommendations. The assessment of sealant retention was performed at two-month interval sessions (n=6), when each sample was scored according to the following criteria: complete retention, partial retention or complete loss. The visual and tactile examinations were carried out with a WHO probe, mouth mirror, air syringe and artificial light. The data were submitted to descriptive statistics and survival analysis. Results: A total of 384 occlusal surfaces were analyzed. Independent of the tooth and evaluation time, slightly better results were achieved by the resin-based sealant, but the difference was not statistically significant. Conclusions: GIC and resin-based sealants achieved similar results with regards to retention during a one-year follow-up period.

A Brazilian study conducted in seven- to ten-year-old children from the rural community showed that caries activity in the permanent first molars was associated with dental fluorosis and malocclusion[8]

Guidelines and systematic reviews of the literature have recommended the use of pit and fissure sealants for populations at high risk for dental caries[2,3,4,5,6,7]. A systematic review of randomized clinical trials reports that pit and fissure sealants on permanent molars reduce the incidence of dental caries among children and adolescents[9]. This is in agreement with the findings of a previous study, in which the authors stated that preventive strategies involving the use of a sealant have significantly contributed to the reduction of dental caries[10]. Dental sealant acts as a mechanical barrier to the accumulation of biofilm[12]
