Annals of International Medical and Dental Research. 2025 Feb; 11(1): 35-392395-28222395-2814https://imsear.searo.who.int/handle/123456789/250010Background: The aim of this study is to investigate the efficacy of arthrocentesis with two needles and to compare it with arthrocentesis with one needle in the treatment of temporomandibular joint (TMJ) internal derangements. Methods: Fifty patients aged between 16 and 60 years comprised the study material in the department. The patient’s complaints were limited mouth opening and TMJ pain. The patients were randomly allocated into two groups, in one group two-needle technique was used, and in other groups single needle was used for arthrocentesis. The procedure was performed under all aseptic conditions. Clinical evaluation of the patients was done before the procedure, at 1 week, and 6 months after the procedure. Intensity of TMJ pain and maximal mouth opening were recorded at each follow-up visit. Results: There was a significant improvement in mouth opening and reduction in pain scores in the post-operative period with P value of (0.001); however, the addition of other needles did not improve the total outcome of the procedure. Conclusion: The two-needle technique does not improve the results compared to single needle technique.Arthrocentesisdouble needleinternal derangementsingle needletemporomandibular joint.Journal ArticleIndiaAssistant Professor, Department of OMFS, GDC Srinagar, JK, IndiaDepartment of Prosthodontics, Karnavati University, Ahmedabad Gujarat, IndiaAssistant Professor, Department of Anesthesia, GMC Srinagar, JK, India
