Comparative evaluation of the length of resin tags, viscosity and microleakage of pit and fissure sealants – an in vitro scanning electron microscope study
INTRODUCTION: In this era of preventive dentistry, many techniques are available for prevention of caries, such as plaque control, use of systemic and local fluorides and pit and fissure sealants. The rationale of pit and fissure sealants is that, when they are applied into the caries prone fissures...

description | INTRODUCTION: In this era of preventive dentistry, many techniques are available for prevention of caries, such as plaque control, use of systemic and local fluorides and pit and fissure sealants. The rationale of pit and fissure sealants is that, when they are applied into the caries prone fissures, they penetrate and seal them from the oral environment. This study aims to correlate the relationship between the viscosity of the sealant, resin tag length and microleakage. MATERIALS AND METHODS: 30 third molars were selected for study. The teeth were randomly divided into 3 groups. Group E: Embrace wetbond, H: Helioseal, G: Guardian seal. Teeth were cleaned with pumice prophylaxis and pretreated with acid etching and bonding agent. The respective pit and fissure sealants were applied. Teeth were placed in 1% methylene blue dye and sectioned mesio-distally into two halves. These were used to assess the microleakage using stereomicroscope and resin tag length using SEM. Viscosity was assessed using Brooke's field viscometer. RESULTS: Viscosity was lowest for Embrace wetbond and highest for Guardian seal. Microleakage scores were highest with Guardian seal and lowest with Embrace wetbond. Resin tag lengths were longer with Embrace wetbond as compared to other groups. There is a definite negative correlation between viscosity, resin tag length and microleakage. Lower the viscosity, the longer were the resin tags and the microleakage decreased. Embrace wetbond pit and fissure sealant had lowest viscosity, longest resin tag length and lowest microleakage scores. CONCLUSION: Embrace wetbond appears to be compatible with residual moisture and ideal for use in children, where isolation is a problem. |
