Dental caries is one of the most common chronic childhood diseases worldwide. In Mexico it is a public health problem.
To identify variables associated with caries occurrence (non-reversible and reversible lesions) in a sample of Mexican schoolchildren.
We performed a cross-sectional study in 640 schoolchildren of 11 and 12 years of age. The dependent variable was the D 1+2 MFT index, comprising reversible and irreversible carious lesions (dental caries) according to the Pitts D 1 /D 2 classification. Clinical examinations were performed by trained and standardized examiners. Using structured questionnaires we collected socio-demographic, socio-economic and health-related oral behaviors. Negative binomial regression was used for the analysis.
The D 1+2 MFT index was 5.68±3.47. The schoolchildren characteristics associated with an increase in the expected average rate of dental caries were: being female (27.1%), having 12 years of age (23.2%), consuming larger amounts of sugar (13.9%), having mediocre (31.3%) and poor/very poor oral hygiene (62.3%). Conversely, when the family owned a car the expected mean D 1+2 MFT decreased 13.5%.
When dental caries occurrence (about 6 decayed teeth) is estimated taking into consideration not only cavities (lesions in need of restorative dental treatment) but also incipient carious lesions, the character of this disease as a common clinical problem and as a public health problem are further emphasized. Results revealed the need to establish preventive and curative strategies in the sample.
龋齿是全球最常见的儿童慢性疾病之一。在墨西哥，它是一个公共卫生问题。
在一组墨西哥学童样本中，确定与龋齿发生（不可逆和可逆性病变）相关的变量。
我们对640名11岁和12岁的学童进行了一项横断面研究。因变量是D1+2 MFT指数，根据皮茨D1 / D2分类，该指数包括可逆性和不可逆性龋损（龋齿）。由经过培训且标准化的检查人员进行临床检查。我们使用结构化问卷收集社会人口统计学、社会经济和与健康相关的口腔行为信息。采用负二项回归进行分析。
D1+2 MFT指数为5.68±3.47。与预期平均龋齿发生率增加相关的学童特征包括：女性（27.1%）、12岁（23.2%）、大量摄入糖分（13.9%）、口腔卫生一般（31.3%）以及差/非常差（62.3%）。相反，当家庭拥有汽车时，预期的平均D1+2 MFT降低13.5%。
当估计龋齿发生情况（约6颗龋齿）时，不仅考虑龋洞（需要进行牙齿修复治疗的病变），还考虑早期龋损，会进一步凸显该疾病作为常见临床问题和公共卫生问题的特征。结果表明需要在该样本中制定预防和治疗策略。
