Several restorative materials with specific indications are used for filling cavities in primary teeth.
To systematically review the literature in order to investigate the longevity of primary teeth restorations and the reasons for failure.
Electronic databases were screened, and eligible studies were hand-searched to find longitudinal clinical studies evaluating the survival of restorations (class I, class II, and crown) placed with different materials in primary teeth with at least one year of follow-up.
Thirty-one studies were included, and a high bias risk was observed. Overall, 12,047 restorations were evaluated with 12.5% of failure rate. A high variation on annual failure rate (AFR) was detected (0-29.9%). Composite resin showed the lowest AFRs (1.7-12.9%). Stainless steel crowns (SSC) had the highest success rate (96.1%). Class I restorations and restorations placed using rubber dam presented better AFR. The main reason for failure observed was secondary caries (36.5%).
An elevated number of failures were observed due to recurrent caries, highlighting the need for professionals to work with a health-promoting approach. The high variation on failure rate among the materials can be due to children's behavior during the procedure, which demands short dental appointments and a controlled environment.
有几种具有特定适应证的修复材料用于填充乳牙的窝洞。
系统综述文献，以调查乳牙修复的寿命和失败的原因。
电子数据库被筛选，并且通过手工检索来寻找评估使用不同材料在具有至少一年随访的乳牙中放置的修复体（I 类、II 类和冠）的生存情况的纵向临床研究。
共纳入 31 项研究，观察到高偏倚风险。总体而言，12047 个修复体的失败率为 12.5%。检测到每年失败率（AFR）的高变异性（0-29.9%）。复合树脂显示出最低的 AFR（1.7-12.9%）。不锈钢冠（SSC）的成功率最高（96.1%）。I 类修复体和使用橡皮障的修复体表现出更好的 AFR。观察到的主要失败原因是继发龋（36.5%）。
由于复发性龋，观察到大量的失败，这突出表明专业人员需要采用促进健康的方法进行治疗。由于材料之间的失败率存在很大差异，这可能是由于儿童在治疗过程中的行为所致，这需要较短的牙科预约和可控的环境。
