Abstract

UNLABELLED

In 1941, Klein and Palmer published a landmark study that ranked the relative susceptibility to dental caries of various morphological tooth types. Specifically, Klein and Palmer used a four-step approach, which included derivation of: (1) an eruption schedule; (2) posteruptive tooth age; (3) cumulative number of decayed, missing, and filled teeth and cumulative posteruptive tooth age; and (4) relative susceptibility values. Their study was conducted when dental caries prevalence and severity were generally high in the United States, prior to the introduction of preventive measures such as fluoride and dental sealants. This investigation used more recent data to assess whether declines in dental caries prevalence over time have been accompanied by changes in the relative susceptibility of permanent tooth types.

METHODS

The data source for this investigation was the oral examination component of the Third National Health and Nutrition Examination Survey. This investigation used analytical methods to derive the relative susceptibility values that were identical with those used during the Klein and Palmer study. Full sample weights were used with SUDAAN so that the descriptive estimates would be representative of the US population. Analysis was limited to children aged 4 through 20 years.

RESULTS

The investigation found six categories of susceptibility, with molars being more susceptible than incisors, canines, or premolars. In general, susceptibility values declined since the Klein and Palmer study, providing additional evidence for a caries decline in the United States. First and second molar susceptibility values from the NHANES III data, however, intersected with those of Klein and Palmer, suggesting that factors specific to the molars, such as the selective use of dental sealants on these teeth, might be playing an additional role.

CONCLUSIONS

Future research should explore factors that might explain the changes in relative susceptibility values over time.

摘要

未标注

1941年，克莱因和帕尔默发表了一项具有里程碑意义的研究，对不同形态类型牙齿的龋齿相对易感性进行了排名。具体而言，克莱因和帕尔默采用了四步方法，其中包括推导：（1）萌出时间表；（2）萌出后牙齿年龄；（3）龋、失、补牙累计数和萌出后牙齿累计年龄；以及（4）相对易感性值。他们的研究是在美国龋齿患病率和严重程度普遍较高时进行的，当时氟化物和牙釉质封闭剂等预防措施尚未引入。本研究使用了更新的数据来评估随着时间推移龋齿患病率的下降是否伴随着恒牙类型相对易感性的变化。

方法

本研究的数据来源是第三次全国健康与营养检查调查的口腔检查部分。本研究采用分析方法得出与克莱因和帕尔默研究中使用的相对易感性值相同的值。在SUDAAN中使用了完整样本权重，以便描述性估计能够代表美国人群。分析仅限于4至20岁的儿童。

结果

该研究发现了六类易感性，磨牙比切牙、尖牙或前磨牙更易患龋齿。总体而言，自克莱因和帕尔默的研究以来，易感性值有所下降，为美国龋齿患病率下降提供了更多证据。然而，来自美国国家健康和营养检查调查（NHANES）III数据的第一和第二磨牙易感性值与克莱因和帕尔默的研究值相交，这表明磨牙特有的因素，如在这些牙齿上选择性使用牙釉质封闭剂，可能正在发挥额外作用。
