[Purpose] Evaluate the association of primary headache and Temporomandibular Dysfunction
in healthy adolescents from the Santos, SP, Brazil. [Participants and
Methods] A total of 208 adolescents, aged 11 to 16 years old were randomly selected at the
dentistry clinic at Universidade Metropolitana de Santos. For that, the Fonseca Anamnestic
Index was applied, including information such as: limitation when opening the mouth and
moving the jaw, headaches, pain in the temporomandibular joint, noises in the
temporomandibular joint, and the habit of tightening or grinding the teeth. The data were
submitted to descriptive statistical analysis and the χ2 test and Fisher’s
exact test were used to evaluate the association of categorical variables. [Results] The
results were 63% of male participants, and 61% of female participants had
Temporomandibular Dysfunction. In both genders headache was associated with the presence
of Temporomandibular Dysfunction, with 93 participants with light headache and 39 with
moderate headache. [Conclusion] There was an association between headache and the presence
of Temporomandibular Dysfunction, and the percentage of affected males was slightly higher
among this association. In the sample of adolescents who presented Temporomandibular
Dysfunction, moderate headache was the main reported symptom of both genders.
