Malnutrition has been consistently associated with caries in primary teeth, although an effect on permanent teeth has not been established because of the few longitudinal studies.
To explore the association between stunting and caries increment in permanent teeth over 3.5 years.
In 2003, 121 children aged 7-9 years were randomly selected from nine underserved communities in Lima (Peru). Parents provided demographic information and a food diary for their children. Clinical examinations included assessments of height, weight, oral hygiene, and dental caries. Stunting was defined using the 2000 CDC and 2007 WHO standards. In 2006, 83 children were re-examined, and the 3.5-year net DMFS increment was calculated. The association between stunting and net DMFS increment was assessed using negative binomial regression.
Stunting was related to net DMFS increment after adjustment for sex and age, oral hygiene, sugary snacks between meals, and caries experience in primary and permanent teeth. Consistent results were found when using either the 2000 CDC (incidence rate ratio: 1.61; 95%CI: 1.07, 2.44) or 2007 WHO standards (IRR: 1.79; 95%CI: 1.28, 2.51).
Stunting was a significant risk factor for caries increment in permanent teeth over a 3.5-year period, independent of other well-known risk factors for caries development.
尽管由于纵向研究较少，尚未确定营养不良对恒牙龋齿的影响，但营养不良与乳牙龋齿一直存在关联。
探讨 3.5 年内儿童身材矮小与恒牙龋齿进展的关系。
2003 年，从利马（秘鲁）的 9 个服务不足的社区中随机选择了 121 名 7-9 岁的儿童。父母为孩子提供了人口统计学信息和饮食记录。临床检查包括身高、体重、口腔卫生和龋齿评估。使用 2000 年 CDC 和 2007 年世卫组织的标准来定义身材矮小。2006 年，对 83 名儿童进行了重新检查，并计算了 3.5 年的净 DMFS 增量。使用负二项回归评估身材矮小与净 DMFS 增量之间的关系。
调整性别和年龄、口腔卫生、餐间含糖零食、乳牙和恒牙龋齿情况后，身材矮小与净 DMFS 增量相关。使用 2000 年 CDC（发病率比：1.61；95%CI：1.07，2.44）或 2007 年世卫组织标准（IRR：1.79；95%CI：1.28，2.51）时均得到一致的结果。
在 3.5 年内，身材矮小是恒牙龋齿进展的一个重要危险因素，独立于其他已知的龋齿发病危险因素。
