Atraumatic restorative treatment fillings and fissure sealants in permanent teeth: a 2-year study

Abstract

OBJECTIVE: To study the feasibility of providing Atraumatic Restorative Treatment (ART) in schools and in rural areas in China, and to evaluate the acceptance and effectiveness of the treatment. METHODS: The study was conducted among 272 grade one students chosen from four different secondary schools in Deyang of Sichuan Province, China. The mean age of the subjects was 12.5 years. 107 boys and 165 girls were found at the baseline examination to have teeth that were suitable for receiving ART fillings or sealants. The treatments were performed within a month using the glass ionomer Ketac-Molar manufactured by ESPE. Evaluation was carried out at 3 months, one year and two years after treatment. RESULTS: ART fillings were placed in 295 permanent teeth, and the 1-year and 2-year success rates were 95.7% and 91.1% respectively. ART sealants were placed in another 191 permanent teeth, and the 3-month, 1-year and 2-year success rates were 95.2%, 89.1% and 78.8% respectively. The incidence of recurrent caries was very low after two years, which were 2.1% and 0.6% for the fillings and sealants respectively. ART was accepted by the majority of the students. CONCLUSION: ART is a simple, acceptable technique, and is suitable for widespread adoption in China.

評價非創傷性治療（ＡＲＴ）技術充填和窩溝封閉的效果及其可接受性，探索適合我國學校和農村開展齲病防治的方法。方法：采用德國ＥＰＳＥ公司生產的Ｋｅｔａｃ－Ｍｏｌａｒ玻璃離子材料完成４８６顆受試牙的充填和窩溝封閉，治療后１年、２年復查，記錄ＡＲＴ充填體、封閉物及繼發齲壞情況。結果：對２９５顆恒牙進行ＡＲＴ充填治療，１年和２年成功率分別達９５．７％及９１．１％；１９１顆牙進行了窩溝封閉，３月、１年、２年成功率分別為９５．２％、８９．１％、７８．８％；ＡＲＴ充填和窩溝封閉后２年繼發齲發生率分別為２．１％和０．６％。ＡＲＴ治療為９１．１％的學生所接受。結論：ＡＲＴ技術操作簡單方便，易學，成功率高，繼發齲低，患者易于接受，可以培訓中初級口腔衛生人員開展此項工作，適合于大規模地推廣應用。
