The aim of this study was to describe and compare findings regarding the prevalence and severity of dental caries when using ICDAS and DMFT/dmft in an epidemiological study with children and their mothers. This cross-sectional study evaluated 150 preschoolers and their mothers. Data were collected with ICDAS and then transformed into DMFT/dmft. ICDAS scores related to caries were analyzed according to three different cut-off-points: CP1 (0-healthy/1-6-caries), CP2 (0-1-healthy/2-6-caries) and CP3 (0-2-healthy/3-6-caries), representing the D/d of DMFT/dmft. ICDAS codes regarding restorations, except sealants, were considered the F/f and the code 97 as the M/m of DMFT/dmft index. Prevalence of caries and its severity with ICDAS were 92%, 84% and 31.3% in children and 97.3%, 96.6% and 80% in adults according to CP1/CP2/CP3, respectively. Admitting CP3 as the standard for data transformation of ICDAS in DMFT/dmft, it was observed that DMFT/dmft index would underestimate 60% of non-cavitated lesions in children and 16.6% in adults. The DMFT/dmft underestimated the presence of disease to disregard non-cavitated lesions for the pediatric population evaluated. The choice of which is the best index for epidemiological surveys will depend on the purpose of the research and the target population: if it is to estimate the needs of the population to determine clinical care in children and adults, the DMFT/dmft may be sufficient. However, if the objective is to have a more comprehensive diagnosis of caries at the population level in order to develop preventive strategies, to halt and reverse the disease, the detection of non-cavitated-lesions becomes important, mainly in young children.
本研究的目的是在一项针对儿童及其母亲的流行病学研究中，描述并比较使用国际龋病检测与评估系统（ICDAS）和龋失补指数（DMFT/dmft）时龋齿的患病率和严重程度的相关发现。这项横断面研究评估了150名学龄前儿童及其母亲。使用ICDAS收集数据，然后将其转换为DMFT/dmft。根据三个不同的临界点分析与龋齿相关的ICDAS评分：CP1（0 - 健康/1 - 6 - 龋齿）、CP2（0 - 1 - 健康/2 - 6 - 龋齿）和CP3（0 - 2 - 健康/3 - 6 - 龋齿），分别代表DMFT/dmft中的D/d。除窝沟封闭剂外，关于修复体的ICDAS编码被视为DMFT/dmft指数中的F/f，编码97被视为M/m。根据CP1/CP2/CP3，儿童龋齿的患病率及其严重程度分别为92%、84%和31.3%，成人分别为97.3%、96.6%和80%。以CP3作为ICDAS在DMFT/dmft中数据转换的标准时，观察到DMFT/dmft指数会低估儿童中60%的非龋洞性病变和成人中16.6%的非龋洞性病变。对于所评估的儿童群体，DMFT/dmft低估了疾病的存在，未考虑非龋洞性病变。对于流行病学调查而言，选择最佳指数将取决于研究目的和目标人群：如果是为了估计人群需求以确定儿童和成人的临床护理，DMFT/dmft可能就足够了。然而，如果目标是在人群层面更全面地诊断龋齿，以便制定预防策略、阻止和逆转疾病，那么检测非龋洞性病变就变得很重要，尤其是在幼儿中。
