Abstract

Fissure sealant is one of effectual method for prevent occlusal caries. Therefore, removing contaminated organic debris and plaque was important process to attain sufficient sealant retention. The aim of this study was revaluated the cleaning method and invasive technique to an occlusal fissure. Twenty-four teeth with deep fissure were used in this study and 15 teeth were cleaned by finger spreader, bristle brush and ultrasonic scalar, respectively. Remain 9 teeth were prepared fissure groove using three kinds of minimal intervention burs (BR-48, CD-50F and CD-53F). The ratio of remaining debris by fingers spreader, bristle brush and ultrasonic scalar were 35 %, 65%, 25% respectively. In contrast, each fissure with invasive technique was not observed residual debris. The average preparative fissure groove by BR-48, CD-50F, CD-53F were 1.38mm, 1.40mm and 0.76mm in width, and 1.58mm, 1.66mm, 1.18mm in depth, respectively. From these results, invasive technique as fissure pretreatment before acid etching might be effective to success for good fissure sealant retention for a deep and narrow fissure and a CD-53F bur was most less preparative sound enamel.
