This study evaluated the prevalence of enamel defects and dental caries and their risk factors on primary and permanent dentitions of prematurely-born children and term children. Eighty children were examined, 40 born prematurely (G1) and 40 born term (G2), in the age group between 5 and 10 years. The demographic variables, medical history and oral health behaviors were recorded on a questionnaire. The teeth were examined for presence of deficiencies of the enamel and caries that were registered. The caries were registered, focusing on the indices dmft (decayed, missing, and filled primary teeth) and DMFT (decayed, missing, and filled permanent teeth). The results showed that 75% of the total sample had enamel defects. The logistic regression model showed that other risk factors such as per capita family income, educational level, dietary and hygiene habits, fluoride exposure, trauma, and diseases had no correlation with enamel defects and caries. A smaller value of total DMFT (0.95) was found in the group of premature children in comparison to the term children (2.07) p = 0.0164. There was no difference concerning the permanent dentition between the two groups (p = 0.9926). One concludes that prematurity can't be a predisposing factor for the presence of dental caries.
本研究评估了早产儿和足月儿的乳牙和恒牙的釉质发育不全和龋齿的患病率及其危险因素。检查了 80 名年龄在 5 至 10 岁之间的儿童，其中 40 名为早产儿（G1），40 名为足月儿（G2）。调查问卷记录了人口统计学变量、病史和口腔健康行为。检查了牙齿有无釉质发育不全和龋齿，并进行了登记。龋齿的登记重点是 dmft（乳牙龋齿、缺失和充填）和 DMFT（恒牙龋齿、缺失和充填）指数。结果表明，总样本中有 75%存在釉质发育不全。逻辑回归模型显示，其他危险因素如人均家庭收入、教育水平、饮食和卫生习惯、氟暴露、创伤和疾病与釉质发育不全和龋齿无关。与足月儿童（2.07）相比，早产儿组的总 DMFT（0.95）值较小（p=0.0164）。两组的恒牙无差异（p=0.9926）。结论是早产不能成为龋齿发生的一个危险因素。
