In this era of preventive dentistry, many dental materials used for prevention of dental diseases are available. Since last few decades efforts are being directed towards prevention of dental caries which is one of the major dental diseases tormenting mankind. The main avenues available are plaque control, use of systemic and local fluorides and use of fissure sealants. There are many factors that contribute towards a successful sealant restoration such as properties of enamel, duration of etching, acid used for etching, manipulative variables. However, one of the prime factors governing the efficacy and life expectancy of a sealant is the marginal adaptability. This study was carried out on a total of 40 intact premolar teeth, which were divided in four main groups and subjected to evaluation under Scanning Electron Microscope. The parameters checked were the width and the number of marginal gaps. The results obtained showed that Teethmate had better marginal integrity and favored the use of invasive technique over non-invasive technique.
