Abstract
Objective: To compare the effectiveness of intra-articular injection and photodynamic therapy (PDT) in the treatment of temporomandibular joint disorder (TMD).
Methods: A retrospective analysis was conducted on the clinical data of 91 TMD patients admitted to our hospital from August 2022 to February 2024. Patients were divided into the control group (n=45, treated with intra-articular injection) and the observation group (n=46, treated with PDT). Clinical outcomes, pain levels [Visual Analog Scale (VAS)], maximum mouth opening, masseter muscle pain threshold, Fricton Temporomandibular Joint Index (including Joints Number (JN), Joint Pain (JP), Muscle Masseter (MM), Disc Displacement Index (DI), Mandibular Position (MP), Pain Index (PI), and Clinical Measurement Index (CMI)], oral health [Oral Health Impact Profile-14 (OHIP-14)], and quality of life [Short Form-36 (SF-36)] were compared between the two groups.
Results: The total effective rate in the observation group (91.30%) was significantly higher than the control group (75.56%) (p<0.05). VAS scores showed significant group (F=5.487), time (F=8.356), and interaction effects (F=6.931) (p<0.05). Within-group comparisons showed a significant decrease in VAS scores 1 and 4 weeks after treatment (p<0.05), with the observation group showing lower VAS scores than the control group (p<0.05). After treatment, maximum mouth opening and masseter muscle pain threshold increased in both groups, with the observation group showing greater improvement (p<0.05). Fricton Temporomandibular Joint Index scores decreased significantly in both groups, with the observation group showing a more significant reduction (p<0.05). OHIP-14 scores decreased, and SF-36 scores increased in both groups, with the observation group showing greater improvement (p<0.05).
Conclusion: PDT is more effective than intra-articular injection in treating TMD. PDT further relieves pain, increases maximum mouth opening and masseter muscle pain threshold, reduces the Fricton index, and improves oral health and quality of life.
期刊介绍:
Therapeutics and Clinical Risk Management is an international, peer-reviewed journal of clinical therapeutics and risk management, focusing on concise rapid reporting of clinical studies in all therapeutic areas, outcomes, safety, and programs for the effective, safe, and sustained use of medicines, therapeutic and surgical interventions in all clinical areas.
The journal welcomes submissions covering original research, clinical and epidemiological studies, reviews, guidelines, expert opinion and commentary. The journal will consider case reports but only if they make a valuable and original contribution to the literature.
As of 18th March 2019, Therapeutics and Clinical Risk Management will no longer consider meta-analyses for publication.
The journal does not accept study protocols, animal-based or cell line-based studies.
