Introduction:

Patients with dentomaxillofacial anomalies of the stomatognathic system often experience temporomandibular joint dysfunction. Besides clinical examination, indices such as Maglione and collaborators' allow to determine the degree of dysfunction.

Objective:

Identify the degree of temporomandibular joint dysfunction in patients with dentomaxillofacial anomalies.

Methods:

A cross-sectional observational descriptive study was conducted of 121 patients attending the Orthodontics Service at Manuel Cedeño Dental Specialties University Clinic from May 2016 to March 2018. The variables analyzed were age, sex and degree of temporomandibular joint dysfunction. Use was made of the Maglione and collaborators' index.

Results:

Patients with dentomaxillofacial anomalies had a mild degree of dysfunction in 71.90 % of the total population. Temporomandibular joint dysfunction was present in 72.58 % of the 18-20 years age group and in the female sex, with 61.98 %.

Conclusions:

Mild temporomandibular joint dysfunction prevailed in patients with dentomaxillofacial anomalies.
