【摘要】 目的　评价非创伤性充填 (ART)治疗恒牙龋的长期效果。方法　采用ART标准器械和步骤 ,用高强度玻璃离子材料对 197名 12～ 13岁儿童完成充填。连续 6年进行临床评价 ,用美国公共卫生服务标准 (USPHS)同时验证。并用标准Rheinberger测量器评价充填的磨损程度。 结果第 6年小Ⅰ类洞充填的保留率为 75 % ,大Ⅰ类洞充填保留率为 6 1% ,差异有统计学意义 (P <0 0 1)。USPHS评价结果表明大、小Ⅰ类洞充填的边缘完整性的满意度各占 80 %和 93%。充填后第 1年Ⅰ类洞磨损值为 4 8μm ,明显高于以后每年的磨损值 2 0～ 2 5 μm(P <0 0 5 )。 结论　ART充填恒牙龋是适合、有效和可接受的 ,其保留率与洞型大小有关 ,是一种有前途的治疗方法 ,但应注意掌握适应证更多还原

【Abstract】 Objective To assess the long effect of atraumatic restorative treatment(ART) restorations in a school environment Methods Five middle level dentists placed 294 ART restorations in the permanent teeth of 197 children Standard instruments and procedures for ART were used The restorative material used was a high strength glass ionomer The restorations were evaluated annually by the same examiner who was not involved in the placement of the restorations Occlusal wear of the restoration was assessed using a standard rheinberger scale At the 5th year examination an independent external examiner evaluated the restorations using USPHS criteria Results The cumulative survival rates of small class I restorations in the sixth year it was 75% The corresponding figures for large class I restorations were 61%( P <0 05) The net wear rate for both the small and large class I restorations in the first year was about 48 μm, which was significantly higher than those of the later years, which were about 20 25 μm ( P <0 05) In the fifth year 93% of the small restorations were assessed as being satisfactory for marginal integrity, as against 80% for the large ones by using USPHS criteria Conclusions The ART approach for treating tooth decay in school children was appropriate, effective and acceptable The 6 year survival rates of the restorations are high but are related to the size and type of the restoration更多还原
