Randomly selected 1,611 individuals aged 18 years formed a nationally representative sample from all provinces of Poland. Developmental defects of the enamel (DDE) and caries were assessed using the modified DDE index, molar incisor hypomineralisation (MIH) Treatment Need Index (MIH-TNI), FDI and WHO criteria by 22 trained and calibrated dentists. T-test was used for comparing group means. A simple and multiple logistic regression tests were used to assess the relationship between DDE and caries severity expressed as DMFT (p < 0.05). The prevalence of DDE was 13.7%. Demarcated opacities (DEO) were the most frequent (9.65%); 4% had diffuse opacities (DIO) and 1.5% had hypoplasia. MIH was diagnosed in 0.6% patients. The prevalence of caries was 93.2%, with mean DMFT of 6.50 ± 4.22. The DMFT value was 7.52 ± 4.77 in the group of patients with demarcated opacities (DEO); 7.85 ± 4.74 with diffuse opacities (DIO) and 7.56 ± 4.57 with enamel hypoplasia, respectively. There was a significant relationship between caries severity and DDE (p < 0.001), DEO (p = 0.001) and DIO (p = 0.038), and between DDE and DMFT index (p < 0.001). The results obtained in the study proved the significant relationship between DDE and DMFT in 18-year-olds, the assessment of which was the aim of the study.
从波兰各省随机抽取 1611 名 18 岁的个体组成具有全国代表性的样本。使用改良的 DDE 指数、磨牙切牙矿化不全（MIH）治疗需要指数（MIH-TNI）、FDI 和世界卫生组织（WHO）标准，由 22 名经过培训和校准的牙医评估牙釉质发育不全（DDE）和龋齿情况。使用 t 检验比较组均值。使用简单和多元逻辑回归检验评估 DDE 与以 DMFT（p<0.05）表示的龋齿严重程度之间的关系。DDE 的患病率为 13.7%。有边界的不透明（DEO）最常见（9.65%）；4%有弥漫性不透明（DIO），1.5%有发育不全。0.6%的患者诊断为 MIH。龋齿的患病率为 93.2%，平均 DMFT 为 6.50±4.22。有边界不透明（DEO）的患者组的 DMFT 值为 7.52±4.77；有弥漫性不透明（DIO）的 DMFT 值为 7.85±4.74；有牙釉质发育不全的 DMFT 值为 7.56±4.57。龋齿严重程度与 DDE（p<0.001）、DEO（p=0.001）和 DIO（p=0.038）之间存在显著关系，且 DDE 与 DMFT 指数之间也存在显著关系（p<0.001）。本研究的结果证明了 18 岁人群中 DDE 与 DMFT 之间存在显著关系，这是本研究的目的。
