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

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, and no complaints were received concerning the sealants’s color.

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.
