Soft-start polymerization of fissure sealant : retention after three years

The aim of this study was to investigate retention of composite fissure sealant polymerized with standard and soft-start technique after three years of clinical trial. Hundred teeth were divided in 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) technique with commercial polymerization unit (Elipar Highlight, Espe). Retention rate in-group A was 72%. In fourteen 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 has not revealed significant differences between polymerization techniques. Complete retention of sealants regardless of group after three years was 76% (76 teeth) with six new caries lesions. Soft-start polymerization showed comparable retention rate as standard polymerization technique.
