To identify individuals affected by severe carious lesions, according to the size of lesion, and to determine the associated factors.
A cross-sectional study was carried out in 1303 children aged 3 to 6 from 10 public preschools with a public preventive dental program. Presence and severity of dental caries were diagnosed using standard criteria (magnitude of carious lesion), which contained four lesion types based on their severity or size. The mothers completed questionnaires to supply information on hygienic habits of the child, and socio-demographics and socioeconomic status variables for the family. Children were examined by one of three calibrated and standardized examiners (kappa>0.85). Adjusted ordinal logistic regression (odds proportional model) was performed to identify associations between caries severity and risk indicators.
The percentages of subjects in severity groups I, II, III and IV were 77.3%, 4.8%, 12% and 5.9%, respectively. We observed that subjects with dmft>4 (sum of decayed, indicated for extraction, and filled primary teeth), presented the severest carious lesions (71.4% vs 6.7%; p<0.001). The variables associated to caries severity were: older age of the child, mother's negative attitude toward dental health, regular and inadequate level of oral hygiene, and an interaction between low socioeconomic level and presence of structural enamel defects.
We observed a low percentage (17.8%) of subjects affected by severe lesion of dental caries (groups III & IV). Well-defined arrays of variables were associated with caries severity.
根据龋损大小确定受严重龋损影响的个体，并确定相关因素。
对10所实施公共预防牙科项目的公立幼儿园的1303名3至6岁儿童进行了一项横断面研究。使用标准标准（龋损程度）诊断龋齿的存在和严重程度，该标准根据严重程度或大小包含四种龋损类型。母亲们填写问卷，提供有关孩子卫生习惯、家庭社会人口统计学和社会经济地位变量的信息。由三名经过校准和标准化的检查人员之一对儿童进行检查（kappa>0.85）。进行调整后的有序逻辑回归（比值比例模型）以确定龋病严重程度与风险指标之间的关联。
I、II、III和IV严重程度组的受试者百分比分别为77.3%、4.8%、12%和5.9%。我们观察到，dmft>4（龋坏、需拔除和已充填乳牙的总和）的受试者龋损最严重（71.4%对6.7%；p<0.001）。与龋病严重程度相关的变量有：儿童年龄较大、母亲对口腔健康的消极态度、口腔卫生水平正常但不足，以及社会经济水平较低与釉质结构缺陷的存在之间的相互作用。
我们观察到受严重龋齿损害（III组和IV组）的受试者比例较低（17.8%）。明确的变量组合与龋病严重程度相关。
