Abstract

Clinical performance of resin-based composite material depends on case selection and on the proficiency of the operator. Especially, composite resin restoration on permanent first molar in children have more limitations clinically than adult patients according to stage of tooth eruption and patient's compliance. This study was designed to evaluate the clinical performance of posterior composite resin restoration in children after 5 years. 35 teeth of 16 patients who were received composite resin restoration on permanent first molar in Department of Pediatric dentistry, Pusan National University Hospital between January 2001 and December 2001 were evaluated based on Modified USPHS criteria. From the finding in this study, following conclusions can be made. 1. 6 teeth(17%) of 35 teeth was replaced, so 5-years survival rate of posterior composite resin restoration is 82.9%. 2. As results of each evaluation criteria, on color match, anatomic form, surface roughness, sensitivity/ discomfort, ideal A grade score was 86.2%, 93.1%, 86.2%, 86.2%, clinically accepted B grade score was 13.8%, 0%, 13.8%, 10.3%. On marginal adaptation and marginal discoloration, A grade score was 13.8%, 44.8% and B grade score was 79.3%, 34.5% and secondary caries rate was 20.7%. 3. 69.1% of teeth (20 teeth) was clinically accepted on all evaluation criteria.

치과용 복합레진(Resin-based composite material)의 임상적 결과는 증례의 선택, 기술적인 완성도, 술자의 숙련도등에 따라 다양하게 나타날 수 있다. 특히, 어린이의 제 1 대구치 복합레진 수복은 치아의 맹출 정도와 환아의 협조도 등에 따라 성인의 경우에 비하여 임상적으로 많은 제약을 가지게 된다. 이에 본 연구는 어린이에 시행된 복합 레진 수복물에 대한 5년 후의 평가를 목적으로 시행되었다. 2001년 1월 1일부터 1년 간 부산대학교병원 소아치과에 내원하여 제 1 대구치 복합레진 수복을 받은 16명 환자의 35개 치아에 대하여 modified USPHS criteria에 근거하여 정밀 평가를 시행한 결과, 다음과 같은 결론을 얻었다. 1. 35개 치아 중 6개(17.1%)는 재수복되어 복합 레진 수복물의 5년 후 생존율은 82.9%로 나타났다. 2. 평가기준별 관찰 결과, 색조의 조화, 마모도, 표면 조도, 민감성 혹은 불편감의 측면에서 이상적인 상태인 A등급은 각각 86.2%, 93.1%, 86.2%, 86.2%로 나타났고, 임상적으로 수용가능한 수준인 B등급은 각각 13.8%, 0%, 13.8%, 10.3%를 보였다. 변연적합성과 변연부 변색의 측면에서 A등급은 각각 13.8%, 44.8%를 보였고 B등급은 79.3%, 34.5%로 나타났으며, 이차 우식의 발생율은 20.7%를 나타내었다. 3. 69.1%인 20개 치아는 7개 항목 모두에서 임상적으로 수용 가능한 것으로 나타났다.
