This study compares the Atraumatic Restorative Treatment (ART) technique to conventional amalgam restorations in the management of dental caries. The present report is limited to the results for one-surface restorations in the permanent dentition over a three-year period. A community field trial was carried out in rural villages in northeastern Thailand. Dental caries was treated using the ART technique in one village where 144 persons were treated with 241 restorations. In a second village, 205 conventional amalgam restorations were provided to 138 persons using mobile dental equipment. Both ART and amalgam restorations were performed by one dentist and two dental nurses without administering local anesthesia. Clinical evaluation was carried out one, two, and three years after placement. The longevity of the restorations was determined by computing the estimated cumulative survival rates according to the life table method. The survival rates of ART restorations (93%, 83%, 71% in years one, two, and three, respectively) were close to those for amalgam restorations (98%, 94%, 85%); however, differences were statistically significant. No statistically significant differences were observed between ART restorations in children and adults, or between those placed by the dentist and dental nurses. Survival rates were lower for occlusal surface restorations compared to those in other surfaces. ART is a feasible approach for the management of dental caries, especially for one-surface lesions in the permanent dentition. Because of its simplicity as a minimal intervention technique, ART can make the control of dental caries available to all people irrespective of their economic and living conditions.
本研究比较了非创伤性修复治疗（ART）技术与传统汞合金修复术在龋齿治疗中的效果。本报告仅限于恒牙列单表面修复三年期的结果。在泰国东北部的乡村开展了一项社区现场试验。在一个村庄采用ART技术治疗龋齿，144人接受了241次修复治疗。在另一个村庄，使用流动牙科设备为138人提供了205次传统汞合金修复。ART修复和汞合金修复均由一名牙医和两名牙科护士在未实施局部麻醉的情况下进行。修复后1年、2年和3年进行临床评估。根据寿命表法计算估计的累积生存率来确定修复体的使用寿命。ART修复体的生存率（第1年、第2年和第3年分别为93%、83%、71%）与汞合金修复体的生存率（98%、94%、85%）接近；然而，差异具有统计学意义。儿童和成人的ART修复体之间，以及牙医和牙科护士所放置的修复体之间，均未观察到统计学上的显著差异。与其他表面的修复体相比，咬合面修复体的生存率较低。ART是一种治疗龋齿的可行方法，尤其适用于恒牙列的单表面病变。由于作为一种微创技术其操作简单，ART可使所有人无论其经济和生活条件如何，都能获得龋齿防治服务。
