: Dental caries is the most prevalent oral condition worldwide. Consequences of untreated dental caries (CUDC) can range from pulp damage and soft tissue ulceration due to root debris to more severe issues, such as fistulas and abscesses. Rural communities might be more vulnerable to CUDC because of lower socioeconomic status, poorer access to healthcare, and lower education levels. The objective of this study was to evaluate and compare the prevalence of CUDC in rural and urban areas in schoolchildren aged 8 to 12 years in the State of Mexico. : A cross-sectional study was conducted using the PUFA index, considering the presence of pulp involvement (P), soft tissue ulcerations due to root remnants (U), fistulas (F), and abscesses (A). The independent variable was the geographic area (rural or urban), and the covariates were nutritional status, hyposalivation, having one's own toothbrush, and having received topical fluoride in the last year. Logistic regression models were fitted, calculating odds ratios (ORs) and 95% confidence intervals (CIs). : The prevalence of CUDC (PUFA > 0) was 42.9% in rural areas and 25.9% in urban areas. Residing in a rural area (OR: 2.15, 95% CI 1.38-3.34, = 0.001), hyposalivation (OR: 1.93, 95% CI 1.11-3.37, = 0.020), and professional fluoride application (OR: 0.15, 95% CI 0.07-0.32, < 0.001) were associated with the prevalence of CUDC. : To prevent caries and its clinical consequences due to the lack of treatment, it is important to promote timely care seeking and access to dental care services, considering the conditions of each geographic area.
龋齿是全球最普遍的口腔疾病。未经治疗的龋齿（CUDC）的后果范围广泛，从牙髓损伤和因牙根残渣导致的软组织溃疡到更严重的问题，如瘘管和脓肿。由于社会经济地位较低、获得医疗保健的机会较差以及教育水平较低，农村社区可能更容易受到CUDC的影响。本研究的目的是评估和比较墨西哥州8至12岁学龄儿童农村和城市地区CUDC的患病率。：采用PUFA指数进行横断面研究，考虑牙髓受累（P）、牙根残留导致的软组织溃疡（U）、瘘管（F）和脓肿（A）的存在。自变量是地理区域（农村或城市），协变量是营养状况、唾液分泌减少、拥有自己的牙刷以及在过去一年接受过局部用氟。拟合逻辑回归模型，计算比值比（OR）和95%置信区间（CI）。：农村地区CUDC（PUFA>0）的患病率为42.9%，城市地区为25.9%。居住在农村地区（OR：2.15，95%CI 1.38 - 3.34，P = 0.001）、唾液分泌减少（OR：1.93，95%CI 1.11 - 3.37，P = 0.020）和专业用氟（OR：0.15，95%CI 0.07 - 0.32，P < 0.001）与CUDC的患病率相关。：为了预防因缺乏治疗导致的龋齿及其临床后果，考虑每个地理区域的情况，促进及时寻求护理和获得牙科护理服务非常重要。
