This randomized clinical trial (RCT) aimed to compare the 3-year survival rates of high viscosity glass ionomer restorations (HVGIC) using conventional cavity preparation and atraumatic restorative technique (ART) in primary molars.
In this RCT, 139 schoolchildren aged 6-9 years with dentinal caries in primary molars were randomly allocated to groups, i.e. the ART group and the conventional group, utilizing a random number generator. Adequate allocation concealment was done. Intervention was delivered using standard procedure and GC Fuji IX ART HVGIC was used as restorations in both the groups. Analysis was carried in 92 participants, and survival rates in both the groups were compared at 12, 24, and 36-month intervals. IBM SPSS software was utilized to analyze the time taken for the procedure and the Kaplan-Meier estimate was used to assess the survival rates. value of 0.05 was considered statistically significant.
The ART took longer to complete (16.48 ± 2.02 min) versus conventional rotary instrumentation (13.15 ± 1.32 min). The conventional method was slightly superior as compared to ART; excellent survival rates (i.e. >90%) were achieved in both groups at the end of 12-month follow-up with no significant differences at the end of 24 and 36 months as evident from Kaplan-Meier estimate ( = 0.255).
Three-year follow-up showed that GIC restorations with ART and conventional method carried out using GC Fuji IX ART HVGIC were acceptably successful, substantiating the use of ART for the primary dentition in areas with high caries prevalence and limited access to dental care.
这项随机临床试验（RCT）旨在比较在乳牙中使用传统窝洞预备和非创伤性修复技术（ART）的高粘度玻璃离子修复体（HVGIC）的3年生存率。
在这项RCT中，使用随机数生成器将139名6 - 9岁患有乳牙牙本质龋的学童随机分配到各组，即ART组和传统组。进行了充分的分配隐藏。采用标准程序进行干预，两组均使用GC Fuji IX ART HVGIC作为修复材料。对92名参与者进行分析，在12、24和36个月的间隔时间比较两组的生存率。使用IBM SPSS软件分析操作所需时间，并使用Kaplan - Meier估计法评估生存率。P值为0.05被认为具有统计学意义。
与传统旋转器械操作（13.15±1.32分钟）相比，ART完成操作所需时间更长（16.48±2.02分钟）。传统方法比ART略优；在12个月随访结束时，两组均取得了优异的生存率（即>90%），从Kaplan - Meier估计法可明显看出，在24个月和36个月结束时两组无显著差异（P = 0.255）。
三年随访表明，使用GC Fuji IX ART HVGIC进行的ART和传统方法的玻璃离子修复体成功率可接受，证实了在龋齿患病率高且获得牙科护理有限的地区，ART可用于乳牙列。
