To investigate the impact of sleep on the development of early childhood caries (ECC).
Seven electronic databases and grey literature were searched with various keyword combinations. Two reviewers independently selected studies, extracted data, and assessed the risk of bias using the Newcastle-Ottawa Scale. The studies were included if they evaluated the impact of sleep parameters on the caries experience or severity of ECC in children under 6 years of age.
Four cross-sectional studies and two longitudinal studies were included. Children who had irregular bedtimes had a 66-71% higher chance of developing ECC. Children who slept after 11 pm might have a 74-85% higher chance of developing ECC. Children who slept less than 8 h during the night had a 30% increased risk of caries than children who slept more than 11 h.
Irregular or late bedtime and fewer sleeping hours could be an independent risk factor for ECC. The risk of ECC might be related inversely in a dose-response manner to the number of sleep hours.
探讨睡眠对幼儿龋（ECC）发生发展的影响。
通过各种关键词组合，在七个电子数据库和灰色文献中进行检索。两位审查员独立选择研究、提取数据，并使用纽卡斯尔-渥太华量表评估偏倚风险。如果研究评估了睡眠参数对 6 岁以下儿童龋病发生或 ECC 严重程度的影响，则将其纳入研究。
纳入了 4 项横断面研究和 2 项纵向研究。睡眠时间不规律的儿童发生 ECC 的几率增加 66-71%。晚上 11 点以后睡觉的儿童发生 ECC 的几率可能增加 74-85%。夜间睡眠时间少于 8 小时的儿童患龋的风险比睡眠时间超过 11 小时的儿童增加 30%。
不规律或晚睡以及睡眠时间较少可能是 ECC 的一个独立危险因素。ECC 的风险可能与睡眠时间呈负相关，呈剂量反应关系。
