Effect of TMJ Arthrocentesis on Capsular Width: An Ultrasonographic Study
ClinicalTrials.gov Studies
Summary
ClinicalTrials.gov registration for NCT07553078, a prospective cohort study at Van Yuzuncu Yil University, Turkey, evaluating the effect of temporomandibular joint arthrocentesis on articular capsular width using ultrasonography. The study received ethics approval (2025/02-07) from Van Yuzuncu Yil University Clinical Research Ethics Committee on February 28, 2025, and is registered as of April 27, 2026. Participants with unilateral intra-articular TMJ disorder receive arthrocentesis with sterile Ringer's lactate solution using a two-needle technique.
“A standard two-needle technique is used, and the upper joint compartment is irrigated with 150-200 mL of sterile Ringer's lactate solution.”
About this source
ClinicalTrials.gov is the NIH-run registry of every clinical trial conducted in the United States, plus most international trials sponsored by US-based companies or institutions. By federal law, sponsors must register Phase 2 through Phase 4 studies before enrolling patients and post results within a year of completion. This feed tracks every new trial registration and study update, around 700 a month: drug interventions, device studies, behavioral protocols, observational research. Watch this if you scout drug candidates moving into mid or late-stage development, monitor competitor pipelines, or follow rare disease research where new trials signal patient hope. GovPing parses sponsor, phase, intervention, and target indication on each entry.

EFFECT OF TMJ ARTHROCENTESIS ON ARTICULAR CAPSULAR WIDTH: AN ULTRASONOGRAPHIC STUDY
N/A NCT07553078 Kind: NA Apr 27, 2026
Abstract
This study is designed as a prospective cohort study evaluating the effect of temporomandibular joint arthrocentesis on articular capsular width using ultrasonography. The study is being conducted at the Faculty of Dentistry, Van Yuzuncu Yil University, Turkey, in accordance with the principles of the Declaration of Helsinki. Ethical approval has been obtained from the Van Yuzuncu Yil University Clinical Research Ethics Committee (approval no. 2025/02-07, dated February 28, 2025).
The study includes systemically healthy adult participants with unilateral intra-articular temporomandibular disorder who have not responded adequately to at least six months of conservative management, including medication, occlusal splint therapy, or physiotherapy. Exclusion criteria are systemic rheumatologic diseases, bony or fibrous ankylosis of the temporomandibular joint, previous open temporomandibular joint surgery, pregnancy or breastfeeding, and active infection.
All participants undergo unilateral temporomandibular joint arthrocentesis performed under local anesthesia by a single experienced oral and maxillofacial surgeon. A standard two-needle technique is used, and the upper joint compartment is irrigated with 150-200 mL of sterile Ringer's lactate solution. No pharmacological agents are injected after the lavage. The contralateral, asymptomatic joint serves as an untreated control.
Ultrasonographic and clinical assessments are performed at three time points: baseline before the ...
Conditions: TEMPOROMANDIBULAR JOINT DISORDER
Interventions: Arthrocentesis with ringer solution
