Abstract
Purpose:
This study aims to assess the influence of superficial heat and Biofreeze on pain,
mouth opening (mm), and quality of life in patients with masticatory myofascial
pain syndrome (MPS).
Materials and methods:
52 patients with MPS were included in the study. They were randomly divided into
two groups. Patients in the Biofreeze group (n = 26) applied 3.5% menthol gel to the
masseter and temporal muscles twice a day for seven days, while the other group
applied superficial heat. Baseline, 7th, and 21st days of VAS, mouth opening (mm),
and Oral Health Impact Profile-14 (OHIP-14) scores of the patients were evaluated
statistically.
Results:
The mouth opening increased by 4.27 ± 3.80 mm in the Biofreeze group and 2.58
± 2.16 mm in the superficial heat group. In each group, a significant decrease in
VAS and OHIP-14 scores was observed on the 7th day compared to the baseline
values (p<0.001). There was no statistically significant difference between the two
applications on myofascial pain, mouth opening (mm), and OHIP-14 total score
variables. The favorable effects of both applications on these parameters were
limited to the duration of use.
Conclusion:
Biofreeze and superficial heat in MPS were found to increase the quality of life, but
the limited effectiveness of these applications underlines the importance of the
underlying factors.
