Minor topic: Technique effectiveness

Type of Article: Double blinded, split-mouth in vivo study

Main Purpose: Evaluate the effectiveness of sealants done with and without primer and bond

Overview of method of research: 78 6-9 year-old with 4 permanent first molars were used in the study. 2 teeth (1 in each arch) were sealed with 3M Scotchbond Multipurpose Plus System prime and bond. 2 (1 in each arch) were sealed without primer or bond (Delton Plus fissure sealant was used for all teeth). Rubber dam isolation and pumice polish were used for all teeth. All teeth were re-evaluated 1 and 2 years later by a single examiner who was blinded to the treatment provided.

Findings: At the 2-year exam, in teeth sealed with primer and bond: 64% sealants completely retained, 23% partially lost, and 13% completely lost. In teeth sealed without primer and bond: 68% of sealants completely retained, 20% partially lost, and 12% complately lost. No statistical significance in sealant retention or caries in teeth sealed with or without bond.

Key points/Summary: No real difference whether or not Scotchbond Multipurpose Plus is used as the bonding agent. Other studies have showed more favorable outcomes with different bonding agents. The author makes a good point that when using a prime and bond system, we should know whether or not it is compatible with the sealant material we are using.

Assessment of article: Very good.
