PERBEDAAN EFEKTIFITAS RETENSI DAN PREVENTIF KARIES BAHAN PIT DAN FISSURE SEALANT

Introduction: Dental caries is a fairly high dental disease that occurs in most countries, which is approximately 60-90% occur in children. Pit and Fissure sealants are materials that are placed on pits and dental fissures that aim to prevent dental caries. There are several types of materials which often used as pit and sealant fissures, including Glass Ionomer Cement (GIC) and Resin-based Sealant/Composite Resin (RK). The purpose of this study is analising the differences in the effectiveness of retention and prevention of caries in GIC and RK pit and fissure sealants in elementary school children. Method: The subjects are 76 permanent teeth of 7-8 years old children with a grouping of 38 teeth each based on the material tested of GIC and RK. Results: There is a significant differences between the pit and fissure sealant material of GIC and RK in the effectiveness of retention and prevention of caries. Conclusion: In the statistical calculation, the comparative effectiveness of retention and caries prevention pit and fissure sealant RK and GIC materials is significant difference. The RK material is more effective in retention and prevention of caries compared with GIC

THE INFLAMMATORY REACTION OF PULP TISSUE WITH CALCIUM HYDROXIDE, MTA AND PORTLAND CEMENT (In Vivo)

Background : Perforation in normal pulp could be happened anytime. In sterile condition, direct pulp capping was the right therapy to maintain the vitality and pulp function. Direct pulp capping agent must contact with the pulp tissue. Generally, body had an immunologic respond with foreign body that contact with tissue. The respond could be inflammatory reaction. The used direct pulp capping agents were calcium hydroxide, and Mineral Trioxide Aggregate (MTA) which known as better agent but relatively expensive and difficult to obtain. So that, the alternative of MTA, Portland cement which was the same essential of MTA, was being developed. The aim of this study, to analized inflammatory reaction of the pulp tissue with direct pulpcapping agents calcium hydroxide, MTA, and Portland cement. Methods: Free caries M. Nemestrina’s posterior teeth were prepared to form pin point perforations on buccal surface of the crowns. The teeth were applied with one of the three capping agents. Teeth were filled and extracted. The extracted teeth were proceed into histopatological preparation slides to evaluate the inflammatic reaction. Results: The result showed no statistically significant differences of pulp inflammatory reaction between calcium hydroxide, MTA and Portland cement in 7, 14, 42, and 90 days. Conclusion: The inflammatory reaction of pulp tissue of the three pulp capping agent (calcium hydroxide, MTA, and PC) were insignificant different
