To evaluate educational strategies and atraumatic restorative treatment (ART)-restoration impact on salivary physicochemical and microbiological characteristics.
Two groups of 6- to 7-year-old children were included: G , with at least one decayed primary molar (n = 36), submitted to four sessions of oral health educational strategy (OHES) and ART restoration; G , a paired caries-free group (n = 36), submitted to four sessions of OHES. Three evaluations were carried out: baseline, 1 week after OHES, and 1 month after OHES or ART, when biofilm and gingivitis frequencies, salivary flow, pH, buffer capacity, calcium and phosphorus concentrations were assessed. Total bacteria and Streptococcus mutans were quantified in unstimulated saliva (qPCR).
Improvement in biofilm and gingivitis scores, salivary pH, and buffering capacity after OHES was observed in G , with a decrease in total bacteria and S. mutans counts. G also showed changes in salivary parameters, even before ART restoration was delivered, and total bacteria count remained lower than baseline 1 month after ART restoration, although a trend to increase the proportion of S. mutans was observed.
Improvements in salivary physicochemical and microbiological characteristics were observed after educational strategies, thus reducing the caries risk of children with decayed teeth, although a trend to increase the S. mutans percentage was observed 1 month after ART restoration.
评估教育策略和非创伤性修复治疗(ART)对唾液理化和微生物特性的影响。
将 6 至 7 岁的儿童分为两组:G 组,至少有一颗龋齿(n=36),接受四次口腔健康教育策略(OHES)和 ART 修复;G 组,配对无龋组(n=36),接受四次 OHES。进行了三次评估:基线、OHES 后 1 周和 OHES 或 ART 后 1 个月,评估时评估生物膜和牙龈炎频率、唾液流量、pH 值、缓冲能力、钙和磷浓度。未刺激唾液中总细菌和变形链球菌(qPCR)的定量。
G 组在接受 OHES 后,生物膜和牙龈炎评分、唾液 pH 值和缓冲能力均有所改善,总细菌和 S. mutans 计数减少。G 组在接受 ART 修复前唾液参数也发生了变化,即使在 ART 修复后 1 个月,总细菌计数仍低于基线,但 S. mutans 比例有增加的趋势。
在接受教育策略后,唾液理化和微生物特性得到改善,从而降低了龋齿儿童的龋齿风险,尽管在接受 ART 修复后 1 个月观察到 S. mutans 比例增加的趋势。
