The effectiveness of a chemically polymerized sealant: four-year results.

Abstract

Using the half mouth technique, a pink-colored, selfcuring, Bis-GMA sealant was placed on the occlusal surfaces of 425 newly erupted first permanent molars in 266 Grade II children. After [our years, 330 pairs of molars were available for reexamination. The number of sealants remaining intact was 226 (68.5%), with 34 partially lost, and 70 completely lost. Of the control teeth, ] 79 (54.2~) became carious or were restored, and 68 (20.6%) of the sealed teeth became carious or were restored-a 62.01~ reduction in caries. The pink color enhanced detection, and no complaints were received concerning the sealants’s color.
