Abstract
ABSTRACT
Background
Restriction in mandibular range of motion (ROM) is one of the main signs of
mandibular dysfunction and an important criterion for evaluation of functional state
of the masticatory system.
Objective
The objective of this study was to evaluate the normal ROM of Temporomandibular
Joint (TMJ) among dental students of tertiary care hospital at central region of Nepal.
Method
After ethical clearance, cross- sectional study was conducted between August to
September 2022 among all dental students who gave consent. The inter-incisal
opening, bilateral lateral excursion and protrusion were measured thrice using 15
cm metallic scale and an average was considered to reduce ambiguity. The data was
entered in Microsoft excel and transferred to SPSS version 20 for statistical analysis.
The descriptive statistics was calculated and independent t test was applied to
compare the mean between genders.
Result
Total of 145 students (25 males and 120 females) were included with the mean age
of 21.32 ± 1.29 years. The overall mean inter-incisal opening was 44.82 ± 5.80 mm,
right lateral excursion was 8.23 ± 2.11 mm, left lateral excursion was 8.70 ± 1.80 mm
and protrusion was 5.65 ± 1.87 mm. There was statistically significant difference in
right and left lateral excursion and protrusion among genders.
Conclusion
The inter-incisal opening of participants in our study appeared towards lower
range of normal mouth opening while lateral excursion appeared consistent with
those described in the literature. The protrusive movement of our participants was
decreased, compared to those recorded in the literature.
