Purpose:
To compare the retention of a multi-use bonding agent (OptiBond) to a conventional sealant (Delton) used as pit and fissure sealants.
Materials And Methods:
An informed consent was obtained from 38 subjects aged 11-17 yrs. Delton, a self-cured sealant, was applied to 86 teeth, and OptiBond, a dual-cure glass filled adhesive, was applied to 85 teeth, under cotton roll isolation and saliva ejector. Each subject received both sealing materials, randomly assigned to the sides of the mouth. The sealed teeth were followed up to 30 months. Clinical evaluation was performed by two examiners and the retention was classified as failure or success.
Results:
Statistical analysis based on a stratified Cox proportional hazards regression model indicated that OptiBond had better clinical performance than Delton (P < 0.001).
