ObjectiveThe aim of this study was to compare the effect of intramuscular injection of botulinum toxin (BTX-A) as an adjunct to arthrocentesis between BTX-A injection only in the treatment of temporomandibular joint disorders (TMD-s) with masticatory muscles tension.Study DesignThe clinical study included 20 TMD patients divided in two groups. The influence of daily activities on pain in the TMJ area was evaluated in both group using the rating scale by List and Helkimo, 1995. Range of maximal interincisial opening (MIO) and joint pain (VAS) were examined to determine the clinical efficiency of the procedures before treatment and after. Group A consisted of 12 patients, they were treated with arthrocentesis and BTX-A injections in the temporal and masseter muscles. Group B consisted of 8 patients, they had only BTX-A injections in the same muscles as mentioned.ResultsIn the group A, VAS decreased significantly (p=0.005) and MIO improved significantly (p<0.005).ConclusionsArthrocentesis with BTX-A seems to effect the clinical outcomes in regards to MIO and VAS compared with the results when BTX-A only was used. BTX-A in combination with arthrocentesis improved the TMJ area symptoms.
