To determine the prevalence of oral potentially malignant disorders (OPMDs) in a population of rural workers in the northeast of Brazil and to investigate the association with sociodemographic, occupational, and health factors.
A total of 1385 workers answered a validated questionnaire and were examined by calibrated dentists. A descriptive analysis, chi-square homogeneity test, and binary logistic regression were performed.
The prevalence of OPMDs was 29.6%. Actinic cheilitis was the most predominant (28.4%), followed by leukoplakia (2.3%) and erythroplakia (0.3%). Gender, type of skin, and time exposed to the sun explained the presence of OPMD (P < 0.0001). The study found increased prevalence, especially for males over the age of 60 years and being exposed to the sun for more than 45 years.
Rural workers showed high vulnerability to the presence of OPMDs, as estimated prevalence exhibited was high.
确定巴西东北部农民工群体中口腔潜在恶性疾病（OPMDs）的患病率，并调查其与社会人口学、职业和健康因素的关联。
共有1385名工人回答了一份经过验证的问卷，并由经过校准的牙医进行检查。进行了描述性分析、卡方同质性检验和二元逻辑回归分析。
OPMDs的患病率为29.6%。光化性唇炎最为常见（28.4%），其次是白斑（2.3%）和红斑（0.3%）。性别、皮肤类型和日晒时间解释了OPMD的存在（P < 0.0001）。研究发现患病率增加，尤其是60岁以上的男性以及日晒超过45年的人群。
农民工显示出对OPMDs存在的高度易感性，因为所显示的估计患病率很高。
