The distribution of enamel developmental defects in 759 11-12-yr-old children from South Wales is described. Overall, 8% of maxillary teeth were affected compared to 3.6% of mandibular teeth. Most teeth were affected equally on right and left sides of the mouth except for maxillary lateral incisors, which had significantly more defects on the right (P less than 0.05) and maxillary first molars, which had significantly more defects on the left (P less than 0.025). Maxillary central incisors (18.7%) were affected by enamel defects most often followed by maxillary first molars (8.1%) and maxillary lateral incisors (7.2%). The ranking order of the teeth varied when the prevalence of the different types of defects was assessed. White demarcated opacities were seen most often in maxillary central incisors (10.8%), yellow demarcated opacities in maxillary first molars (1.8%), diffuse opacities in maxillary central incisors (6.6%) and hypoplasias in mandibular first premolars (1.5%). Defects of all types occurred most frequently on the buccal surfaces of the teeth. In premolar and molar teeth more defects occurred on the occlusal surface than on the lingual.
本文描述了来自南威尔士的759名11至12岁儿童牙釉质发育缺陷的分布情况。总体而言，上颌牙受影响的比例为8%，而下颌牙为3.6%。除上颌侧切牙右侧的缺陷明显更多（P<0.05）以及上颌第一磨牙左侧的缺陷明显更多（P<0.025）外，口腔左右两侧的大多数牙齿受影响程度相同。上颌中切牙（18.7%）最常受到牙釉质缺陷的影响，其次是上颌第一磨牙（8.1%）和上颌侧切牙（7.2%）。在评估不同类型缺陷的患病率时，牙齿的排名顺序有所不同。白色界限性混浊最常见于上颌中切牙（10.8%），黄色界限性混浊见于上颌第一磨牙（1.8%），弥漫性混浊见于上颌中切牙（6.6%），发育不全见于下颌第一前磨牙（1.5%）。所有类型的缺陷最常出现在牙齿的颊面。在前磨牙和磨牙中，咬合面出现的缺陷比舌面更多。
