사람에서 압축공기 세정(Air-polishing)을 사용한 치은연하 처치 후 임상적, 미생물학적 평가에 대한 연구

Abstract

Biofilm, which is an organizational group of microorganism on tooth surface, makes periodontal disease. It is important to remove biofilm mechanically for treatment and preservation of periodontal disease. Air polishing is a method to remove biofilm on tooth surface by spraying pressed air mixed powder with water. The purpose of this study is to evaluate the efficacy of air-polishing compared to SRP In this study, 15 patients diagnosed as chronic periodontitis and single-root tooth over 5mm of pocket depth symmetrically in left and right quadrant. was investigated. Subgingival debridement is performed by scaling and root planing(SRP) and air-polishing. And the results are evaluated and compared clinically and microbiologically. Probing pocket depth(PPD), bleeding on probing(BOP), relative attachment level(RAL) and change of gingival crevicular fluid(GCF) were assessed before treatment and 14 and 60 days after treatment. Microbial analysis was assessed at pre-treatment, post-treatment and 14 and 60 days after treatment. After treatment, PPD and BOP was decreased, and attachment gain was observed in air polishing. There was no clinical difference compared to SRP. The volume of GCF decreased at 14 days and increased again at 60 days. Comparing to SRP, there was a statistical significance of the volume of GCF at 60 days in air-polishing. In microorganism, high-risk bacteria to cause periodontal disease decreased remarkably. It decreased immediately after treatment but increased again as time went by. For this study, subginigival debridement by air-polishing was effective for decrease of pocket depth, attachment gain, decrease of GCF and inhibition of microorganism. The further study should compare Air-polishing to SRP according to degree of pocket depth and calculus existence.
