To evaluate the effect of a chlorhexidine-gluconate-based cavity disinfectant on the clinical performance of high viscosity glass-ionomer cement following the ART approach under field conditions after 24 months.
126 school children 6-8 years old who had bilateral matched pairs of carious Class I and II primary molars were included. A split mouth design was used in which Ketac Molar was randomly placed with or without the use of chlorhexidine-gluconate-based cavity disinfectant on contralateral sides by three dentists. The restorations were evaluated after 6, 12 and 24 months by two experienced examiners using USPHS-Ryge criteria.
The 24-month mean cumulative survival rates of Ketac Molar without the use of disinfectant were 97.7% and 69.4% while in the disinfectant group, the survival rates were 95.2% and 63.9% in Class I and II restorations, respectively with no significant difference between the groups in both class types. In the non-disinfected group, large Class II cavities had significantly better survival rates than did small Class II cavities (P = 0.023). In the disinfected group, the failure rates in mean cumulative survivals from 6 to 12 months and 12 to 24 months significantly increased with time (P = 0.004 and P = 0.016 respectively).
评估在现场条件下，基于葡萄糖酸洗必泰的窝洞消毒剂对采用非创伤性修复治疗（ART）方法充填24个月后的高粘性玻璃离子水门汀临床性能的影响。
纳入126名6 - 8岁有双侧配对的Ⅰ类和Ⅱ类龋坏乳牙的学童。采用双侧对照设计，由三名牙医在对侧随机使用或不使用基于葡萄糖酸洗必泰的窝洞消毒剂来放置Ketac Molar。两名经验丰富的检查人员在6个月、12个月和24个月后依据美国公共卫生署（USPHS）- Ryge标准对修复体进行评估。
未使用消毒剂时，Ketac Molar在24个月时的平均累积生存率，Ⅰ类修复体为97.7%，Ⅱ类修复体为69.4%；而在消毒剂组中，Ⅰ类和Ⅱ类修复体的生存率分别为95.2%和63.9%，两类修复体组间均无显著差异。在未消毒组中，大的Ⅱ类洞的生存率显著高于小的Ⅱ类洞（P = 0.023）。在消毒组中，6至12个月和12至24个月的平均累积生存率的失败率随时间显著增加（分别为P = 0.004和P = 0.016）。
