This cross-sectional study aimed at evaluating the oral health conditions of building construction workers from a city in the mid-west region of São Paulo, Brazil. This study involved 219 male subjects, aged 17 to 72. The definition of a random sample utilized the functional number of each worker as a criterion to the raffle, which took into account all 450 subjects registered in the Working Accidents Prevention Program. The examination of oral health conditions by DMFT index and need of treatment were carried out according to WHO criteria (1997). This paper reports the prevalence of caries according to age, occupation, and educational level. Among the 219 workers examined, the mean DMFT was 16.9. Amongst the younger workers (<25 years-old), 21.3 teeth showed no need of treatment, while the older ones showed increasing treatment needs (p<0.001). The DMFT values were 15.6 for the administrative duties and 21.7 for foremen and bricklayers, although the differences were not statistically significant. The DMFT index showed an increase with age for all groups (p<0.001). The self-reported need of treatment was associated with a smaller DMFT for people that reported a positive response when compared with subjects that did not report these needs (p<0.05). These differences were statistically significant, as tested by ANOVA and Student t test. Among the building construction workers, in this study, important oral lesions were not observed, despite the daily exposition to some risk factors for oral cancer.
