The use of pit and fissure sealants has been reported to increase exposure to xenoestrogens. Because these estrogen-mimics are suspected of having many deleterious effects in animals, and perhaps humans, several types of studies were undertaken by our Biocompatibility Group. We confirmed that bisphenol A (BPA) and bisphenol A dimethacrylate (BPA-DM) have proliferative effects in cells with high...

Background and Aim: One of the important factors in microleakage of fissure sealants is saliva contamination. Researchers believe that applying bonding agents can reduce the microleakage. The present study compared the microleakage of a fissure sealant contaminated with artificial saliva at different curing times with or without using a bonding agent. Materials and Methods: In this in-vitro ...

This paper reviews key issues of sealant use and methodology and poses recommendations to inform the discussion toward a consensus statement by participants. A comprehensive review of sealant literature, including policy recommendations from previous conferences that reviewed best practices for sealant use, was completed. Building on the review paper by Simonsen and on previous policy statement...

Pit and fissure sealants are safe effective preventive measures for reducing the risk of tooth decay in pediatric patients. The procedure applying is a relatively quick non-invasive process that typically involves preparation, isolation, etchant application. They used on occlusal surfaces molars premolars, which have deep grooves fissures difficult to clean. Sealants mostly applied permanent ch...

BACKGROUND: Increased dental caries and dental lesions have made preventive measures, especially among children, inevitable. This study investigated elementary schoolgirls’ mothers’ level of knowledge on preventive methods against dental caries. METHODS: In this cross-sectional study, mothers of 250 schoolgirls were randomly selected from five regions of Tehran, Iran. Their knowledge about fiss...
