A comparative study of two pit and fissure sealants: three-year results in Augusta, Ga

Abstract

A total of 254 children were examined 36 months after a single application of sealant. In 128 children, 201 permanent first molars were treated with Delton, and, in 126 children, 205 permanent first molars were treated with Nuva-Seal. Delton was completely retained on 80% of all paired permanent first molars, partially retained on 10%, and completely lost on 10% of the study teeth. Nuva-Seal was completely retained on 60% of all paired permanent molars, partially retained on 21%, and completely lost on 19% of the study teeth. Delton was 69% effective in preventing occlusal caries on permanent first molars three years after a single application. Nuva-Seal was 39% effective in preventing occlusal caries on permanent first molars three years after a single application. Both sealants have been shown to prevent dental caries on permanent first molars of children three years after a single application.

Effect of operator variability and patient age on the retention of fissure sealant resin: 3‐year results

“…These levels of effectiveness are much lower ihan other workers have reported when using Dellon resin. BojANiNitV «/, (1) produced 92% effectiveness after 1 year whilst BROOKS et al (2) reported Delton to be 69% effective after 3 years. MCCIINE et al (4) reported Delton to be 85% effective with 45 teeth saved for every 100 sealed.…”

New Priorities in Prevention of Oral Disease *

“…Success in preventing gingivitis and caries in children has been reported by the Axelsson-Lindhe group in their studies at Karlstad, They applied intensive prophylactic procedures every two weeks over a two-year period. In the third year, the time between these "professional cleanings," as the research group refers to them, was increased to four weeks for the 7-11 year olds, and to eight weeks for the [13][14] year olds. The continuing good results with this reduced frequency of cleaning was attributed to the background effects of the first two years.51…”
