To evaluate the effectiveness of a xylitol pediatric topical oral syrup to reduce the incidence of dental caries among very young children and to evaluate the effect of xylitol in reducing acute otitis media in a subsequent study.
Double-blind randomized controlled trial.
Communities in the Republic of the Marshall Islands.
One hundred eight children aged 9 to 15 months were screened, and 100 were enrolled. Intervention Children were randomized to receive xylitol topical oral syrup (administered by their parents) twice a day (2 xylitol [4.00-g] doses and 1 sorbitol dose) (Xyl-2 x group) or thrice per day (3 xylitol [2.67-g] doses) (Xyl-3x group) vs a control syrup (1 xylitol [2.67-g] dose and 2 sorbitol doses) (control group).
The primary outcome end point of the study was the number of decayed primary teeth. A secondary outcome end point was the incidence of acute otitis media for reporting in a subsequent report.
Ninety-four children (mean [SD] age, 15.0 [2.7] months at randomization) with at least 1 follow-up examination were included in the intent-to-treat analysis. The mean (SD) follow-up period was 10.5 (2.2) months. Fifteen of 29 of the children in the control group (51.7%) had tooth decay compared with 13 of 32 children in the Xyl-3x group (40.6%) and eight of 33 children in the Xyl-2x group (24.2%). The mean (SD) numbers of decayed teeth were 1.9 (2.4) in the control group, 1.0 (1.4) in the Xyl-3x group, and 0.6 (1.1) in the Xyl-2x group. Compared with the control group, there were significantly fewer decayed teeth in the Xyl-2x group (relative risk, 0.30; 95% confidence interval, 0.13-0.66; P = .003) and in the Xyl-3x group (0.50; 0.26-0.96; P = .04). No statistical difference was noted between the 2 xylitol treatment groups (P = .22).
Xylitol oral syrup administered topically 2 or 3 times daily at a total daily dose of 8 g was effective in preventing early childhood caries.
评估木糖醇儿童外用口服糖浆降低幼儿龋齿发病率的有效性,并在后续研究中评估木糖醇降低急性中耳炎发病率的效果。
双盲随机对照试验。
马绍尔群岛共和国的社区。
筛查了108名9至15个月大的儿童,100名儿童入组。干预措施:将儿童随机分为接受木糖醇外用口服糖浆(由其父母给药),每日两次(2剂木糖醇[4.00克]和1剂山梨醇)(Xyl-2x组)或每日三次(3剂木糖醇[2.67克])(Xyl-3x组),与对照糖浆(1剂木糖醇[2.67克]和2剂山梨醇)(对照组)。
研究的主要结局终点是乳牙龋坏数量。次要结局终点是后续报告中急性中耳炎的发病率。
在意向性分析中纳入了94名至少进行了1次随访检查的儿童(随机分组时平均[标准差]年龄为15.0[2.7]个月)。平均(标准差)随访期为10.5(2.2)个月。对照组29名儿童中有15名(51.7%)患龋齿,而Xyl-3x组32名儿童中有13名(40.6%),Xyl-2x组33名儿童中有8名(24.2%)。对照组龋坏牙齿的平均(标准差)数量为1.9(2.4)颗,Xyl-3x组为1.0(1.4)颗,Xyl-2x组为0.6(1.1)颗。与对照组相比,Xyl-2x组的龋坏牙齿明显更少(相对风险,0.30;95%置信区间,0.13 - 0.66;P = 0.003),Xyl-3x组也更少(0.50;0.26 - 0.96;P = 0.04)。两个木糖醇治疗组之间未观察到统计学差异(P = 0.22)。
每天以8克的总剂量局部使用2次或3次木糖醇口服糖浆对预防幼儿龋齿有效。
