PURPOSE: The aim of this study was to evaluate the effect of the simplified conditioning on durability of polyacid-modified resin composite (PMRC; Dyract Seal) fissure sealants. The effectiveness of a nonrinsing conditioner (NRC) on retention of PMRC sealants (92) was studied in a split-mouth design. METHODS: The enamel of 1 molar was pretreated with NRC and coated with Prime & Bond NT (Dentsply DeTrey, Konstanz, Germany)/PMRC. The contralateral molar was conditioned with 36% phosphoric acid and sealed with Delton. The sealant retention was evaluated during 2 years. In addition 49 pairs were sealed with Prime & Bond NT/PMRC after conditioning with 36% phosphoric acid and evaluated after 1 year. RESULTS: Significantly higher loss rates at 1 and 2 years were observed for the NRC/Prime & Bond NT/PMRC sealants. At 2 years, partial and total loss rates for Delton were 23% and 11%, and for NRC/Prime & Bond NT/PMRC sealants were 44% and 40%, respectively. At 1 year, phosphoric acid-conditioned Prime & Bond NT/PMRC sealants showed significantly better retention than the NRC-conditioned PMRC sealants and the phosphoric acid-conditioned Delton sealants. CONCLUSIONS: Conditioning with NRC prior to sealant application cannot be recommended. |
