This study aimed to compare the effectiveness of semi-annual application of 38% silver diamine fluoride (SDF) with and without light curing in arresting dentine caries in primary teeth.
Children aged 5-7 years with at least 1 active dentine carious lesion were randomly allocated into: Group 1 (38% SDF with light curing: applied SDF for 10 seconds and exposed to LED light for 20 seconds) and Group 2 (38% SDF without light curing: applied SDF for 10 seconds and isolated for 20 seconds). Both interventions were repeated every 6 months. At the baseline, demographic data, oral health-related behaviors and clinical parameters of the children were collected. The activity of carious lesion was assessed using the visual-tactile method and adverse effects, if any, were recorded at both 6-month and 12-month follow-up periods by the same examiner. Intention-to-treat analysis was employed to analyze the data.
At baseline, 40 children (218 lesions) and 37 children (261 lesions) were recruited into Group 1 and Group 2. There were no significant differences between the 2 groups in terms of demographic data, oral health-related behaviors, and clinical parameters of the children at baseline (P > .05). After 12 months, 66 out of 77 children (85.74%) remained in the study. There was no significant difference in caries arrest rate between Group 1 (74.8%) and Group 2 (69.0%) with P = .161.
The semi-annual application of 38% SDF with or without light curing is equally effective in arresting dentine carious lesions in primary teeth. The addition of light curing to SDF-treated teeth has no significant effect in arresting dental caries in primary teeth.
本研究旨在比较每半年应用一次38%氟化银氨（SDF）并光照固化与未光照固化在阻止乳牙牙本质龋方面的效果。
将年龄在5至7岁且至少有1处活动性牙本质龋损的儿童随机分为：第1组（38% SDF光照固化组：涂抹SDF 10秒，然后接受LED光照20秒）和第2组（38% SDF未光照固化组：涂抹SDF 10秒，隔离20秒）。两种干预措施均每6个月重复一次。在基线时，收集儿童的人口统计学数据、口腔健康相关行为和临床参数。采用视诊-探诊法评估龋损的活动性，并由同一名检查者在6个月和12个月的随访期记录任何不良反应。采用意向性分析来分析数据。
在基线时，第1组招募了40名儿童（218处龋损），第2组招募了37名儿童（261处龋损）。两组儿童在基线时的人口统计学数据、口腔健康相关行为和临床参数方面无显著差异（P > 0.05）。12个月后，77名儿童中有66名（85.74%）仍在研究中。第1组（74.8%）和第2组（69.0%）的龋病阻止率无显著差异，P = 0.161。
每半年应用一次38% SDF并光照固化或未光照固化在阻止乳牙牙本质龋损方面同样有效。在SDF治疗的牙齿上增加光照固化对阻止乳牙龋齿没有显著效果。
