The aim of this study was to investigate the prevalence and psychosocial impact of enamel defects among 16-year-old school children on the island of Penang. The data were collected through a self-administered questionnaire survey and an oral examination, using the Modified Developmental Defects of Enamel Index (FDI, 1992). In all, 1024 subjects were selected using a multistage random sampling technique. About two-thirds of the sample (67.1%) had at least one tooth affected by enamel defects. Enamel opacities accounted for 85.6% of the total condition. Diffuse-type opacity predominated (63.5%). Among subjects who expressed dissatisfaction, 18.8% reported covering their mouths when smiling, 8.7% avoided going out with friends and 39.1% had consulted their dentists. About 17% of the subjects reported that their parents had complained about the color of their front teeth but only 5.7% had experienced being teased by their friends about the problem. Two-thirds of the subjects were affected by enamel defects involving at least one tooth; however, the esthetic perception and psychosocial impact of those affected were minor.
本研究旨在调查槟城岛16岁在校儿童牙釉质缺陷的患病率及其社会心理影响。数据通过自填式问卷调查和口腔检查收集，采用改良的牙釉质发育缺陷指数（FDI，1992）。总共使用多阶段随机抽样技术选取了1024名受试者。约三分之二的样本（67.1%）至少有一颗牙齿受到牙釉质缺陷影响。牙釉质浑浊占所有情况的85.6%。弥漫型浑浊占主导（63.5%）。在表示不满的受试者中，18.8%报告微笑时会捂住嘴，8.7%避免与朋友外出，39.1%咨询过牙医。约17%的受试者报告父母曾抱怨过他们前门牙的颜色，但只有5.7%曾因这个问题被朋友取笑过。三分之二的受试者至少有一颗牙齿受到牙釉质缺陷影响；然而，受影响者的审美观念和社会心理影响较小。
