J Dent Res:青春期牙科氟中毒严重程度下降:一项队列研究

2020-04-08 MedSci原创 MedSci原创

牙齿氟中毒是由于牙齿形成过程中氟化物摄入过多而引起的。然而,关于氟中毒的发病率和严重程度是否会随着时间的推移而改变或如何改变,文献中的证据很少。

牙齿氟中毒是由于牙齿形成过程中氟化物摄入过多而引起的。然而,关于氟中毒的发病率和严重程度是否会随着时间的推移而改变或如何改变,文献中的证据很少。

 

本研究中,研究人员在9岁、13岁、17岁和23岁时进行了永久性的牙齿检查,作为爱荷华州氟化物研究的一部分,该研究从出生起就对一个队列进行了跟踪研究。使用氟中毒风险指数(FRI)和Russell的鉴别诊断标准对氟中毒进行了评估。

 

计算人和牙齿水平的氟中毒严重程度:在人水平的第二高FRI评分(确定每颗牙齿的最高FRI评分,并使用第二高FRI评分的牙齿)和牙齿水平的最高FRI评分。

 

在人和牙齿水平上,在整个青少年时期和青年时期都观察到轻度到中度氟中毒严重程度的下降。在人水平的每一对相邻检查中,对于基线第二高FRI为0的参与者,大多数参与者的基线第二高FRI保持在0(82%-91%)。许多基线第二高FRI为1的参与者的随访分数为0(47%-54%),而约三分之一的参与者的随访分数为1(34%-38%),更低的比例增加到2(9%-15%)。对于基线第二高FRI评分为2的参与者,25%-44%的参与者的随访FRI评分分别为0、1和2。在牙齿水平上也观察到了类似的模式。这些结果与大多数现有的、有限的文献一致。

 

总的来说,氟中毒的严重程度,最初是轻度到中度,在青春期和青年时期趋于下降。还需要进一步研究这一趋势如何影响对氟中毒的审美观念。
