Atraumatic Restorative Treatment (ART) is one of the strategies used to control dental caries; it involves hand instruments for removal of carious tissue, and restorations using high-viscosity Glass Ionomer Cement (GIC). The present controlled clinical trial aimed to evaluate the performance of low-cost GIC indicated for ART in primary teeth, compared with high-viscosity GIC, after one year of follow-up. Two-to six-year-old children with dentin caries lesions on one or two surfaces of anterior and posterior teeth were selected. The children were randomly assigned to 2 groups according to the restorative material used: G1 (control) - Ketac Molar®; G2 (experimental) - Vitro Molar®. Treatments were performed in a school setting, following the guidelines of the ART. A total of 728 restorations were performed in 243 children. Descriptive analysis and Poisson regression were applied, with a significance level of p < 0.05. After 12 months, 559 (76.8%) restorations were re-evaluated. The success rate was evaluated by the prevalence ratio (PR), associated with restorations performed in primary second molars (PR = 1.21; 95%CI = 1.03-1.42), and with small (PR = 1.35; 95%CI = 1.14-1.60) or medium cavities (PR = 1.29; 95%CI = 1.08-1.55), using Ketac Molar® material (PR= 1.07; 95%CI = 1.01-1.15), considering p < 0.05. Small or medium restorations in primary second molars performed with high-viscosity GIC (Ketac Molar®) were more successful than restorations performed with low-cost GIC indicated for ART.
无痛性修复治疗（ART）是控制龋齿的策略之一；它涉及用于去除龋坏组织的手动器械，以及使用高粘度玻璃离聚物水泥（GIC）进行修复。本项对照临床试验旨在评估低成本 GIC 在原发性牙齿中的性能，该材料用于 ART，与高粘度 GIC 相比，在一年的随访后。选择有 1 或 2 个前牙和后牙的牙本质龋损的 2 至 6 岁儿童。根据使用的修复材料将儿童随机分为 2 组：G1（对照）- Ketac Molar®；G2（实验组）- Vitro Molar®。在学校环境中按照 ART 指南进行治疗。在 243 名儿童中进行了总共 728 次修复。应用描述性分析和泊松回归，显著性水平为 p < 0.05。12 个月后，559 次（76.8%）修复进行了重新评估。采用流行率比（PR）评估成功率，与原发性第二磨牙（PR = 1.21；95%CI = 1.03-1.42）和小（PR = 1.35；95%CI = 1.14-1.60）或中腔（PR = 1.29；95%CI = 1.08-1.55）进行的修复相关，使用 Ketac Molar®材料（PR = 1.07；95%CI = 1.01-1.15），p < 0.05。用高粘度 GIC（Ketac Molar®）进行的原发性第二磨牙的小或中腔修复比低成本 GIC 指示的 ART 修复更成功。
