Abstract：
OBJECTIVE: The study aimed to evaluate temporary fillings using Biodentine™ in asymptomatic deep carious lesions after 12, 24, and 36 months in school children from the remote village of Kerung, Nepal.
METHODS: From November 2018 to November 2019, 91 temporary fillings were placed using Biodentine™ (a hydraulic calcium silicate cement) in permanent molars with deep carious lesions of schoolchildren in the remote district of Kerung, Nepal. These restorations were performed after selective caries removal in a non-dental setting with hand instruments and cotton roll isolation, as electric motors and saliva ejection systems were unavailable. In total, 78 single-surface and 13 multi-surface fillings were placed. Clinical and radiographic follow-up periods encompassed 12, 21, and 33 months, respectively.
RESULTS: After 12 months, all single-surface fillings (100%) survived, whilst all multi-surface fillings were partially or entirely lost. The survival rate of single-surface restorations after 21 and 33 months was 67.6% and 50%, respectively. Radiographically, no pathology was observed.
CONCLUSIONS: This study showed that Biodentine could be used in deep carious lesions as a temporary filling in single-surface lesions for at least up to 1 year and in a substantial number of cases for up to 21 and 33 months.

摘要：
目的：该研究旨在评估在12、24和36个月后使用Biodentine™对来自偏远村庄Kerung的学童无症状的深龋病变进行临时填充。尼泊尔。
方法：从2018年11月至2019年11月，使用Biodentine™（一种水硬性硅酸钙水泥）在基隆偏远地区学龄儿童的永久性磨牙中放置了91个临时填充物，尼泊尔。这些修复体是在非牙科环境中使用手器械和棉卷隔离进行选择性龋齿去除后进行的，因为没有电动马达和唾液喷射系统。总的来说,放置78个单面和13个多表面填充物。临床和影像学随访期包括12、21和33个月，分别。
结果：12个月后，所有单面填充物(100%)存活,而所有多表面填充物都部分或全部丢失。21个月和33个月后单面修复体的成活率分别为67.6%和50%,分别。射线照相,未观察到病理。
结论：这项研究表明，生物牙本质可用于深层龋齿病变，作为单表面病变的临时填充至少长达1年，在大量病例中可用于21个月和33个月。
