| Abstract: | Objective: To compare the efficacy of the double- and single-needle arthrocentesis techniques in removing methylene blue from the temporomandibular joint (TMJ) space. Methods: This study was performed in 20 TMJs from 10 fresh cadavers. A total of 1 ml of 10 μM methylene blue solution was injected into the upper joint spaces, just prior to irrigation. Ten arthrocentesis procedures were carried out using the double-needle technique, and the remaining 10 were completed using the single-needle technique. The photo-absorbance values of methylene blue solution injected into and removed from the joint space were measured at a 665 nm wavelength. Statistical analysis was performed using Shapiro–Wilks test and t-test. Results: The t-test analysis showed no statistically significant difference between the two methods in the removal of methylene blue. Conclusion: According to the results of the present study, the single-needle technique may be a good alternative with the advantages of easier application in cases where it is not possible to perform the double-needle technique. |
