To study the clinical manifestation and its pathogenesis of the developmental enamel defects in primary dentition of children with low birth weight and premature birth history.
One hundred and seventy-six children (aged 3-8 years old) were studied about the clinical manifestation of the developmental enamel defects in the primary dentition and its relationship with their medical history.
The prevalence of enamel defects in primary dentition in these children was 77.3%. There was no significant correlation between enamel defects and gender. Enamel opacity mostly affected the upper and lower second primary molars. Enamel hypoplasia mostly affected the maxillary and mandibular primary incisors and the maxillary first primary molars.
Enamel defects mainly result from children's general disorder at birth or within one year after birth.
研究低出生体重和有早产史儿童乳牙牙釉质发育缺陷的临床表现及其发病机制。
对176名3至8岁儿童的乳牙牙釉质发育缺陷的临床表现及其与病史的关系进行了研究。
这些儿童乳牙牙釉质缺陷的患病率为77.3%。牙釉质缺陷与性别之间无显著相关性。牙釉质混浊主要影响上下第二乳磨牙。牙釉质发育不全主要影响上颌和下颌乳切牙以及上颌第一乳磨牙。
牙釉质缺陷主要是由儿童出生时或出生后一年内的全身性疾病引起的。
