Many different factors are known to cause and
perpetuate the symptoms of temporomandibular
disorders (TMD). However, the roles of parafunctional
factors have not been clearly elucidated. We
found one of these habits in the clinical setting.
This parafunctional habit involves daily light
touching of the upper and lower teeth, when the
mouth is closed. We named this habit Teeth
Contacting Habit (TCH). [Objectives] To investigate
the following hypotheses: 1) TCH is associated with
perpetuation of chronic pain of TMD patients; 2)
TCH is associated with other behavioral factors.
[Methods] Two hundred and twenty-nine TMD outpatients
with chronic pain were analyzed with
multivariate logistic regression models. [Results]
TCH was found in 52.4% of patients. Patients with
TCH and pain lasting for more than four months
were less likely to experience improvements in pain
at the first visit (OR = 1.944, p = 0.043). Other factors
associated with TCH were as follows: unilateral
chewing (OR = 2.802) and involvement in a precision
job (OR = 2.195). [Conclusion] TCH can
prolong TMD pain and is associated with other
behavioral factors.
