摘要

目的:本研究通过扫描电子显微镜(SEM)研究了含氟化亚锡(SnF2)和氟化钠(NaF)的牙膏与单独含氟化钠的牙膏对牙周病变牙齿的封堵效果,并与健康牙齿进行了比较。方法:选取单根前磨牙牙质标本60份,其中因正畸原因拔牙15份(H组),因牙周破坏拔牙15份(P组)。每组标本进一步分为HC和PC组(对照组),H1和P1组(SnF2和NaF处理组),H2和P2组(NaF处理组)。每天刷两次,连续7天,保存在人工唾液中,扫描电镜检查。在×2,000放大下评估开放小管的直径和小管的数量。结果:H组与P组开放小管直径相近。H1、P1、H2、P2组开放小管数量显著低于HC、PC组(P < 0.001),与闭塞小管百分比一致。P1组小管闭塞率最高。结论:虽然发现两种牙体都能成功地咬合小管,但含有SnF2和NaF的牙体在牙周受累牙齿中提供了最高程度的咬合。

Occlusion of dentinal tubules on periodontally involved teeth by dentifrice containing stannous fluoride and sodium fluoride.

Purpose: This study examined the occlusion effect of a dentifrice containing stannous fluoride (SnF2) and sodium fluoride (NaF) on periodontally involved teeth in comparison with healthy teeth using scanning electron microscopy (SEM) in comparison with a dentifrice containing NaF alone.

Methods: Sixty dentine samples obtained from single-rooted premolars, 15 of them extracted for orthodontic reasons (Group H) and 15 because of periodontal destruction (Group P), were included in the study. Each group of specimens was further divided into subgroups: HC and PC (control), H1 and P1 (treated with SnF2 and NaF), and H2 and P2 (treated with NaF). The samples were brushed twice a day for 7 days, kept in artificial saliva, and examined by SEM. The diameters of open tubules and the numbers of tubules were assessed at ×2,000 magnification.

Results: The H and P groups showed similar diameters of open tubules. The numbers of open tubules in Groups H1, P1, H2, and P2 were significantly lower than in Groups HC and PC (P < 0.001), and consistent with the percentages of occluded tubules. Group P1 had the highest percentage of occluded tubules.

Conclusions: Although both dentifrices were found to successfully occlude dentinal tubules, the dentifrice containing SnF2 and NaF provided the highest degree of occlusion in periodontally involved teeth.
