Objective: To verify the prevalence and association between temporomandibular disorder and low back pain in undergraduate students from Brazil. Methods:Analyptical cross-sectional study with a quantitative approach, carried out on 600 undergraduate students from the University Center of Sciences and Technology of Maranhão, in the city of Caxias. The Fonseca Anamnestic Index was used to assess the prevalence of temporomandibular disorderand the Brazil’s Economic Classification Criterion to characterize the economic class of the students. Results:The demographic profile of the participants showed that 63.8% were female, 66.8% were aged ≤23 years and 85.2% belonged to economic classes B and C. The prevalence of temporomandibular disorder was 62.3% and the prevalence of low back pain was 46.5%, of which 73.8% were associated with TMD (p<0.0001). The presence of low back pain was a risk factor twice higher for the development of temporomandibular disorder (p<0.0001). Conclusion: It was possible to verify the significant prevalence of temporomandibular disorder and low back pain among undergraduate students, with a statistically significant association. However, it is not possible to perceive a cause-effect relationship between the pathologies based only on the use of anamnestic indexes.
