Microscopic Evaluation of Different Sealant Materials

Objectives: The aim of this study was to compare in vitro penetration and adaptation of light curing ormocer based fissure sealant and non­filled low viscosity sealant material. Materials and Methods: Extracted human molars (n = 108) were randomly assigned to 2 groups. Admira Seal and Teethmate F­1 were used as sealant materials in the study. Each tooth was sectioned using an Isomet cutter into 2 portions bucco­lingually, producing mesial and distal tooth halve. The penetration, adaptation and voids of 2 materials were evaluated according to fissure shape and depth at the stereo­light microscope, and from each group 10 samples were examined under scanning electron microscope (SEM). Results: Under light microscope and SEM, ormocer based fissure sealant (Admira Seal) and non­filled low viscosity sealant material (Teethmate F­1) did not show significantly different statistical results when penetration and adaptation were compared (p>0.05).
