Tooth wear is common in the deciduous dentition. A recent study suggests that tooth wear in the deciduous dentition is related to subsequent tooth wear in adults, so that early identification of factors related to tooth wear could be of long-term benefit. The purposes of this study were to describe patterns of tooth wear in the deciduous dentition and to relate tooth wear to occlusal characteristics and longitudinal dietary patterns. Data were collected as part of a longitudinal study of a cohort of children recruited at birth from Iowa hospitals. Stone casts were obtained in the deciduous dentition stage, and 355 children, 4 to 5 years old, met the selection criteria. Tooth wear was categorized for each tooth as none, mild, moderate, or severe, and related to occlusal characteristics and longitudinal data on fruit juice and soft drink consumption. All children exhibited some tooth wear on at least 1 tooth, and nearly 16% of them had at least 1 tooth with severe wear. Tooth wear was generally more severe in the maxillary arch and the anterior teeth. Severe tooth wear on the molars was significantly related to posterior crossbites, but severe tooth wear on the incisors was related to Class III canine relationships. There were no statistically significant relationships between tooth wear and soft drink or fruit juice consumption. Based on our results, we concluded that mild tooth wear is universal in the deciduous dentition, but only a few occlusal factors are related to severe tooth wear. Tooth wear was not related to any dietary patterns we investigated.
乳牙列中的牙齿磨损很常见。最近一项研究表明，乳牙列中的牙齿磨损与成人后续的牙齿磨损有关，因此早期识别与牙齿磨损相关的因素可能具有长期益处。本研究的目的是描述乳牙列中的牙齿磨损模式，并将牙齿磨损与咬合特征和纵向饮食模式联系起来。数据收集是对爱荷华州医院出生时招募的一组儿童进行的纵向研究的一部分。在乳牙列阶段获取石膏模型，355名4至5岁的儿童符合入选标准。将每颗牙齿的磨损程度分为无、轻度、中度或重度，并与咬合特征以及果汁和软饮料消费的纵向数据相关联。所有儿童至少有一颗牙齿出现了某种程度的磨损，近16%的儿童至少有一颗牙齿重度磨损。上颌牙弓和前牙的牙齿磨损通常更严重。磨牙的重度磨损与后牙反合显著相关，但前牙的重度磨损与Ⅲ类犬牙关系有关。牙齿磨损与软饮料或果汁消费之间没有统计学上的显著关系。基于我们的研究结果，我们得出结论，轻度牙齿磨损在乳牙列中很普遍，但只有少数咬合因素与重度牙齿磨损有关。牙齿磨损与我们调查的任何饮食模式均无关。
