Abstract

SUMMARY
Background: Temporomandibular joint
dysfunction and pain syndrome (TMJD)
has been identified as one of the principle
causes of non-dental pain in the orofacial
region.
Objective: To describe the prevalence of
TMJD and associated factors in the students
of the faculty of odontology of the University
Cooperativa de Colombia (UCC),
Envigado campus
Materials and methods: Observational,
descriptive and cross-sectional study. 98
randomly selected students were evaluated.
A survey, clinical examination, Helkimo
index, emotional distress and anxiety test
was performed. Univariate and bivariate
analysis was performed (Chi2, p<0,05).
Results: 66% were women. The average
age was 21 years (SD±3). 26,5% had
dental clenching habit, 26,5% and 18,4%
onicofagia bruxism. 31,6% reported joint
click, 30,6% headache or neck pain, 18,4%
pain in the temporomandibular joint (TMJ)
and 12,2% mandibular stiffness. Clinically,
44,5% presented unilateral chewing. 62,2%
showed deviation on opening and 81,6% on
closing. 42,9% had anxiety disorder and to
a lesser extent panic disorder. 74,7% had
mild TMJD. No difference was found with
statistical significance between the prevalence
of sex TMJD. (Chi2, p=0,255) or any
association with anxiety disorders (Chi2, p
=0,060), and distress.
Conclusions: Mild TMJD was most
frequent among the student population.
Clenching habits, nail biting and unilateral
chewing were identified. No difference was
found by gender or any association with
anxiety disorder or anxiety. Particularly
striking is the high prevalence of unilateral chewing and anxiety disorder, which are
important to study.
