Background: Temporomandibular joint disorder (TMD) can significantly affect the quality of life of individuals. However, evidence of TMD involvement and the extent of the impacts caused by it, in groups exposed to a stressful routine, are still scarce. Therefore, the aim of the present study was to evaluate the prevalence of TMD signs and symptoms and their impact on quality of life related to oral health in construction workers. Material and methods: This cross-sectional study included only male individuals. Illiterate workers and functional illiterate were excluded. The diagnosis of TMD was established according to the Research Diagnostic Criteria for TMD (RDC/TMD). The Oral Health Impact Profile questionnaire validated for Portuguese (OHIP-14) was used to assess the impact of TMD on oral health and quality of life. Descriptive analysis of TMD signs and symptoms was performed. Data related to the OHIP-14 questionnaire were compared using the Mann-Whitney U test. Pearson's correlation was also performed. The established alpha of this study was 5%. Results: 230 individuals were included. The mean age was 37.8 (SD=11) years. The most frequent TMD sign and the symptom was disc displacement, 86 (37.39%) of the individuals. OHIP-14 demonstrated a statistically significant difference when compared to all TMD signs and symptoms (p<0.001). A weak correlation was observed between pain and OHIP-14 (r=0.366; p<0.0001). Conclusion: TMD affects oral health and quality of life for construction workers.
