Abstract
Background: TMD is a multifactorial disorder significant research
efforts have been invested in finding its etiologies and management
to improve their quality of life.
Objectives: To evaluate and compare digital occlusal parameters,
depression, anxiety and serum cortisol level between
temporomandibular disorder patients and control group.
Material and methods: A sample size of 24 TMD patients and 24
apparently healthy age and sex matched controls were recruited in
the study. The patients occlusion time and disclusion time was
recorded using T-Scan III, the level of anxiety and depression was
evaluated by using Hospital Anxiety and Depression scale
questtionaire and serum cortisol was evaluated by collecting fasting
blood sample, under aseptic conditions.
Results: The incidence of premature contacts (occlusal
interferences), clusion time and disclusion time was significantly
longer in TMD group than in control subjects. The anxiety and
depression scores were statistically significant in TMD group
compared to control group, but no statistically significant difference
was observed in serum cortisol levels.
Conclusion: The present study demonstrated increase in the premature contacts i.e occlusal interferences were high
with increase in clusion time, disclusion time, anxiety and depression scores in TMD group, where as no significant
increase in serum cortisol levels was seen among TMD group even though their anxiety and depression levels were
high. Hence, patients with temporomandibular disorders should always be evaluated for stress and anxiety along
with the T- Scan evaluation of occlusal prematurities and correction of the same.
