This study examined the association between enamel opacities and dental caries in a population from North Wales with low levels of fluoride in the drinking water. Those subjects with only diffuse (n = 317) types of opacity had a mean DMFS of 1.6 (+/- 3.4) compared with those having only demarcated (n = 1,408) opacities of 3.4 (+/- 4.3). The group with both (n = 317) types of defect present had a DMFS of 2.4 (+/- 3.7) and the group with no defects (n = 1,496) had a DMFS of 2.7 (+/- 3.8). These differences were statistically significant (p < 0.001). Possible reasons for these differences are discussed.
本研究调查了北威尔士饮用水中氟含量较低人群的牙釉质混浊与龋齿之间的关联。仅患有弥漫性（n = 317）混浊类型的受试者平均龋失补指数（DMFS）为1.6（±3.4），而仅患有界限性（n = 1,408）混浊的受试者该指数为3.4（±4.3）。同时存在两种（n = 317）缺陷类型的组DMFS为2.4（±3.7），无缺陷组（n = 1,496）的DMFS为2.7（±3.8）。这些差异具有统计学意义（p < 0.001）。文中讨论了造成这些差异的可能原因。
