|
Purpose we examined the change of function and pain by improvement of the temporomandibular joint during low-level laser(LLL) and transcutaneous electrical nerve stimulation(TENS) to adults who show temporomandibular disorder.
Methods: This study was conducted with temporomandibular disorders. Participants were randomly divided into two group (LLL vs TENS). The TENS was applied at a frequency of 4Hz and intensity for 15 minutes. The LLL was applied with a power of 40㎷ per laser at 685nm wavelength in continuous wave mode. This study were conducted three times a week for a total of 4 weeks.
Results: The LLL was associated with more significant improvements in mouth opening (p<0.01, 95% CI: 1.910-7.023), and masticatory muscle pressure threshold(p<0.05; 95% CI: 0.027-0.943).
Conclusion: Our findings indicate that LLL was more effective than TENS in the treatment of TMD. Such findings highlight the need to develop and promote a controlled therapy program to facilitate a return to normal daily activities in patients with TMD.
