Major topic: Strength of Sealants filled vs unfilled
Minor topic(s: Saliva contaminated vs. non-saliva contaminated
Type of Article: Scientific
Main Purpose: To determine shear bond strength of an unfilled resin based sealant Clinpro vs. a filled resin based sealant Fluroshield in saliva contaminated and non-saliva contaminated enamel.
Overview of method of research: 40 permanent molars were sectioned in half and embedded in polyester resin. They were divided into 2 groups without contamination and with contamination of saliva. These were further subdivided into Clinpro and Fluroshield. Shear bond strength was then tested.
Findings: Fluroshield provided higher bond strength in the absence of contamination. There was no statistically significant difference between the two groups in that were contaminated with saliva.
Key points/Summary: Under dry conditions the filled sealant yielded better bonding performance. If contaminated with saliva both materials yielded lower bond strengths.
Assessment of article: Good article
