Abstract

The aim of this study was to investigate retention of composite fissure sealant polymerized with standard and softstart
technique after a three year clinical trial. One hundred teeth were divided into two groups (A&B) of teeth and sealed
with composite material (Visioseal, 3M Espe) using split mouth design. Sealants were polymerized using standard
(Group A) and soft-start (Group B) techniques with commercial polymerization unit (Elipar Highlight, 3M Espe). Retention
rate in Group A was 72%. In 14 teeth sealant was partially or completely missing. Group B showed retention rate of
80%. Sealant was partially or completely missing in 10 teeth. Six new caries lesions in Group A (3) and B (3) were detected.
Mann-Whitney test did not reveal significant differences between the polymerization techniques. After three years
complete retention of sealants, regardless of the group, was 76% (76 teeth) with six new caries lesions. Soft-start polymerization
showed a comparable retention rate as the standard polymerization technique.
