Prevalence and factors associated with oral potentially malignant disorders in Brazil′s rural workers

Abstract

Objectives

Determine the prevalence of Oral Potentially Malignant Disorders in a population of rural workers in the northeast of Brazil and investigate the association with socio-demographic, occupational and health factors.

Methods

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.

Results

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 old and being exposed to the sun for more than 45 years.

Conclusion

Rural workers showed high vulnerability to the presence of OPMDs, as estimated prevalence exhibited was high.
