J Clin Med 2023; 12:4655. [PMID: 37510770 PMCID: PMC10380303 DOI: 10.3390/jcm12144655] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 06/27/2023] [Accepted: 07/11/2023] [Indexed: 07/30/2023] Open
Abstract
This mapping review aims to identify and discuss current research directions on intracavitary temporomandibular joints (TMJs) injections. The inclusion criteria allowed studies published in the last full six years, based on patients diagnosed with temporomandibular joint disorders (TMDs), treated by TMJ intra-articular injections. Medical databases covered by the Association for Computing Machinery, Bielefeld Academic Search Engine, PubMed, and Elsevier Scopus engines were searched. The results were visualized with tables, charts, and diagrams. Of the 2712 records identified following the selection process, 152 reports were qualified for review. From January 2017, viscosupplementation with hyaluronic acid (HA) was the best-documented injectable administered into TMJ cavities. However, a significant growing trend was observed in the number of primary studies on centrifuged blood preparations administrations that surpassed the previously leading HA from 2021.

Wu CB, Sun HJ, Sun NN, Zhou Q. Analysis of the Curative Effect of Temporomandibular Joint Disc Release and Fixation Combined with Chitosan Injection in the Treatment of Temporomandibular Joint Osteoarthrosis. J Clin Med 2023; 12:jcm12041657. [PMID: 36836193 PMCID: PMC9966182 DOI: 10.3390/jcm12041657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 02/01/2023] [Accepted: 02/10/2023] [Indexed: 02/22/2023] Open
Abstract
OBJECTIVE Temporomandibular joint osteoarthritis (TMJ-OA) is common in clinic. The purpose of this study was to evaluate the efficacy of disc release, fixation and chitosan injection in the treatment of TMJ-OA. METHODS From March 2021 to March 2022, 32 patients who underwent the unilateral reduction and fixation of temporomandibular joint disc release were retrospectively studied. All patients were diagnosed with TMJ-OA and were treated with chitosan injection. This group of patients was analyzed by the visual analog scale (VAS) for pain and improvement of maximum comfortable mouth opening before treatment and 6 months after treatment. A paired t-test was used to evaluate the treatment effect, and p < 0.05 indicated that the difference was statistically significant. RESULTS All 32 patients were successfully treated by surgery and chitosan injection in the second week after operation. The duration of disease in this group ranged from 1 to 10 months, with an average of 5.7 months. After 6 months of follow up, 30 patients were satisfied with the treatment and two were unsatisfied. The difference in the treatment effect was found to be statistically significant (p < 0.05). CONCLUSIONS Temporomandibular joint disc release and fixation combined with chitosan injection is effective in the treatment of TMJ-OA.

Temporomandibular Joint Osteoarthritis: Pathogenic Mechanisms Involving the Cartilage and Subchondral Bone, and Potential Therapeutic Strategies for Joint Regeneration. Int J Mol Sci 2022; 24:ijms24010171. [PMID: 36613615 PMCID: PMC9820477 DOI: 10.3390/ijms24010171] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/13/2022] [Accepted: 12/17/2022] [Indexed: 12/24/2022] Open
Abstract
The temporomandibular joint (TMJ) is a specialized synovial joint that is crucial for the movement and function of the jaw. TMJ osteoarthritis (TMJ OA) is the result of disc dislocation, trauma, functional overburden, and developmental anomalies. TMJ OA affects all joint structures, including the articular cartilage, synovium, subchondral bone, capsule, ligaments, periarticular muscles, and sensory nerves that innervate the tissues. The present review aimed to illustrate the main pathomechanisms involving cartilage and bone changes in TMJ OA and some therapeutic options that have shown potential restorative properties regarding these joint structures in vivo. Chondrocyte loss, extracellular matrix (ECM) degradation, and subchondral bone remodeling are important factors in TMJ OA. The subchondral bone actively participates in TMJ OA through an abnormal bone remodeling initially characterized by a loss of bone mass, followed by reparative mechanisms that lead to stiffness and thickening of the condylar osteochondral interface. In recent years, such therapies as intraarticular platelet-rich plasma (PRP), hyaluronic acid (HA), and mesenchymal stem cell-based treatment (MSCs) have shown promising results with respect to the regeneration of joint structures or the protection against further damage in TMJ OA. Nevertheless, PRP and MSCs are more frequently associated with cartilage and/or bone repair than HA. According to recent findings, the latter could enhance the restorative potential of other therapies (PRP, MSCs) when used in combination, rather than repair TMJ structures by itself. TMJ OA is a complex disease in which degenerative changes in the cartilage and bone develop through intricate mechanisms. The regenerative potential of such therapies as PRP, MSCs, and HA regarding the cartilage and subchondral bone (alone or in various combinations) in TMJ OA remains a matter of further research, with studies sometimes obtaining discrepant results.

Abstract
The number of people suffering from temporomandibular joint osteoarthritis (TMJOA) has been increasing. TMJOA cause joint noise, pain on TMJ and/or masticatory muscles, and restricted mandibular movement, which disturb eating, laughing and conversation, and impose serious lifestyle impediments. Chondrocyte apoptosis, extracellular matrix degradation, synovitis, and subchondral bone remodeling are the main pathological features of TMJOA. Various drug delivery systems are developed to controlled release at specific activation sites with high bioactivity and inhibit rapid dilution to enable long-term therapeutic response, which present great potential for the treatment of TMJOA. This review focuses on recently developed drug delivery systems by different administration in the TMJOA treatment, and summarizes their effects, duration, safety, and limitations, which would pave the way for development of TMJOA therapy.

Intra-articular injection of hyaluronic acid versus platelet-rich plasma following single puncture arthrocentesis for the management of internal derangement of TMJ: A double-blinded randomised controlled trial. J Craniomaxillofac Surg 2022; 50:825-830. [PMID: 36372680 DOI: 10.1016/j.jcms.2022.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2021] [Revised: 07/17/2022] [Accepted: 10/14/2022] [Indexed: 11/11/2022] Open
Abstract
The present study aimed to compare the efficacies of intra-articular injections of platelet-rich plasma (PRP) and hyaluronic acid (HA) following single needle arthrocentesis in patients with TMJ internal derangement. This double-blinded randomised controlled trial involved the enrolment of patients diagnosed with unilateral TMD, falling into either Wilkes' stages II or III. In Group A, single needle arthrocentesis was performed using Ringer's lactate serving as a control group; in Group B, intra-articular injection of 1 ml hyaluronic acid injection was given following arthrocentesis; and in Group C, autologous intraarticular injections of 1 ml of PRP was given after arthrocentesis, twice in two weeks' interval. The primary outcome variables were maximum mouth opening and pain, while TMJ clicking sounds formed the secondary outcome variable. All the outcome variables were assessed preoperatively (T0) and postoperatively after the second dose of injection at one month (T1), three months (T2), and six months (T3). The alpha level was set to p < 0.05. Ninety patients (N = 90) comprised the final sample size of the study with thirty patients(n = 30) in each treatment group. A statistically significant decrease in the management in mean pain scores was noted between T0 [mean scores were 7.30 ± 1.05 (Group A), 7.63 ± 1.12 (Group B), and 7.56 ± 1.04(Group C)] and T3 [mean scores were 2.66 ± 0.88 (Group A), 2.4 ± 0.72 (Group B), and 1.66 ± 0.66 (Group C)] time intervals between Group A and C(p < 0.001). Significant improvement was noted in preoperative maximum mouth opening (MMO) of Group A, B, and C which was 22.83 ± 3.58, 22.17 ± 4.07, and 21.37 ± 3.69, respectively to 28.90 ± 2.72, 32.17 ± 3.97, and 34.10 ± 3.80 mm, respectively at six months postoperatively (p < 0.001). A significant decrease in joint sounds was evident for all three groups(p = 0.003 for Group A, p < 0.001 for Group B, and p < 0.001 for Group C) across the time intervals. Moreover, Group C showed a significant decrease in the prevalence of joint sound compared to the other two groups at all-time intervals postoperatively when equated to baseline (p = 0.02 at T1, p = 0.009 at T2, and p = 0.002 at T3). Within the limitations of the present study, it can be concluded that intra-articular PRP may be preferable over HA whenever appropriate, following single needle arthrocentesis in the treatment of TMJ internal derangement.

Abstract
Musculoskeletal pain is the most common pain reported by patients. Platelet-rich plasma (PRP) is widely used to treat musculoskeletal pain. However, the efficacy of PRP to treat this pain remains controversial. This review highlights the application of PRP in the treatment of musculoskeletal pain. PRP treatment appears to reduce pain and improve function in patients with musculoskeletal pain. However, there are limitations to the currently published studies. These limitations include the PRP preparation methods, type of activators, types of pathology to be treated, methods and times of administration, and association of PRP with other treatments.

Abstract
The aim of this narrative review was to present research investigating chitosan, including its general characteristics, properties, and medical and dental applications, and finally to present the current state of knowledge regarding the efficacy of chitosan in the treatment of temporomandibular disorders (TMDs) based on the literature. The PICO approach was used for the literature search strategy. The PubMed database was analyzed with the following keywords: (“chitosan”[MeSH Terms] OR “chitosan”[All Fields] OR “chitosans”[All Fields] OR “chitosan s”[All Fields] OR “chitosane”[All Fields]) AND (“temporomandibular joint”[MeSH Terms] OR (“tem-poromandibular”[All Fields] AND “joint”[All Fields]) OR “temporomandibular joint”[All Fields] OR (“temporomandibular”[All Fields] AND “joints”[All Fields]) OR “temporo-mandibular joints”[All Fields]). After screening 8 results, 5 studies were included in this review. Chitosan presents many biological properties and therefore it can be widely used in several branches of medicine and dentistry. Chitosan promotes wound healing, helps to control bleeding, and is used in wound dressings, such as sutures and artificial skin. Apart from its antibacterial property, chitosan has many other properties, such as antifungal, mucoadhesive, anti-inflammatory, analgesic, antioxidant, antihyperglycemic, and antitumoral properties. Further clinical studies assessing the efficacy of chitosan in the treatment of TMD are required. According to only one clinical study, chitosan was effective in the treatment of TMD; however, better clinical results were obtained with platelet-rich plasma.

Intraarticular injections of platelet rich plasma and plasma rich in growth factors with arthrocenthesis or arthroscopy in the treatment of temporomandibular joint disorders: A systematic review. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2021; 123:e327-e335.

Abstract
Intra-articular platelet rich plasma injections [PRP] or platelet rich growth factors [PRGF] injections have been used as therapeutic treatment options for patients with temporomandibular joint disorder [TMD] in recent years. The purpose of this paper is to evaluate the level of the available scientific evidence in the current literature on the benefits of applying PRP or PRGF injections to patients with TMD simultaneously or after arthrocentesis or arthroscopy to reduce post-operative pain and improve temporomandibular joint function. This systematic review was conducted according to PRISMA criteria and an electronic database search was carried out in the PubMed, Scopus and Cochrane databases during May 2021. The patients in the study group were injected with intra-articular PRP or PRGF simultaneously or after arthrocentesis or arthroscopy while the patients in the control group had arthrocentesis or arthroscopy without an intra-articular injection or received an injection of hyaluronic acid or Ringer's lactate solution. Eight randomised controlled clinical trials were selected. The PRP and PRGF intra-articular injections demonstrated significant differences in terms of pain reduction in three studies and improved mandibular function in two. The treatment with PRP or PRGF intra-articular injections demonstrated slightly better clinical results but of little significance in comparison with the control group. Evidence of their effectiveness is crucial to establish them as non-invasive treatments and as an affordable option for treating some types of TMDs. In accordance with Evidence-based dentistry principles, this review has been assigned a C recommendation.

Abstract
BACKGROUND The effectiveness of platelet-rich plasma (PRP) injection combined with physical therapy for the treatment of temporomandibular joint osteoarthritis (TMJ-OA) has not been studied. OBJECTIVES To assess the effectiveness of PRP injection combined with individualised comprehensive physical therapy for the treatment of TMJ-OA. METHODS This prospective cohort study included 40 patients with TMJ-OA who received PRP injection or PRP injection combined with individualised comprehensive physical therapy. Pain intensity, maximum mouth opening, temporomandibular joint sounds, and the Jaw Functional Limitation Scale (JFLS) scores and imaging findings were compared before treatment and during follow-up. RESULTS The pain intensity, maximum mouth opening, and temporomandibular joint sounds of the two groups significantly improved with an increase in treatment time (p < .05). The pain improvement in the combined treatment group was greater than that in the PRP injection group at 3 and 6 months (p < .05). The improvement of mouth opening was better in the combined treatment group, whereas the improvement of joint sounds was better in the PRP injection group. The improvement in JFLS scores in the combined treatment group was greater than that in the PRP injection group at 6 months (p < .05). The imaging improvement rates of the two groups were similar. CONCLUSIONS Platelet-rich plasma injection can significantly improve pain, mouth opening, abnormal joint sound, and mandibular function in patients with TMJ-OA and has good repair effect on condylar bone defects. PRP injection combined with individualised comprehensive physical therapy can effectively control the medium- and long-term pain of patients.

Abstract
BACKGROUND Platelet-rich plasma (PRP) has been widely used to treat various orthopaedic diseases, and there are a large number of studies on the matter. However, there have been no bibliometric reports on the publications in this field. Bibliometrics is an excellent method to systematically evaluate the current research status of a specific field. In this study, CiteSpace 5.7.R2 software was used to analyse the status, hotspots, and frontiers of PRP in the treatment of orthopaedic diseases in the past 19 years. METHODS All articles about the application of PRP in orthopaedics from 2002 to 2020 were searched from the Web of Science Core Collection. The author, country, institution, journal, cited journal, and keywords were retrieved, and the bibliometric analysis was done in CiteSpace 5.7.R2. RESULTS A total of 321 articles were retrieved. The analysis showed that the number of publications increased in the past 19 years, and the most productive author in this field was Brian J. Cole. The most productive country and the most productive institution were the US and the Hospital for Special Surgery in New York, respectively. The journals with the highest output and the highest citation frequency were the Journal of Orthopaedic Research and the American Journal of Sports Medicine, respectively. From the keyword analysis, we observed that the primary research hotspots were the study of the PRP composition, growth factors, and the combination of PRP and mesenchymal stem cells. The frontiers of PRP were in vivo experiments, the treatment of rotator cuff and cartilage injury, and the comparison of clinical efficacy between PRP and hyaluronic acid. CONCLUSION The efficacy of PRP in treating orthopaedic diseases remains controversial. There are still some problems with the experimental methods, such as insufficient sample size, low level of evidence, confusion of system naming, lack of standardisation of preparation methods and application programs, and lack of in-depth basic scientific research. The research status shown by co-occurrence and cluster maps and the analysis of hotspots and frontiers may help solve present problems and explore new directions.

Abstract
CONTEXT Internal derangements of temporomandibular joint (TMJ) with associated symptoms which do not respond to conservative therapies are refractory cases of temporomandibular joint dysfunction syndrome (TMD). Minimally invasive techniques like arthrocentesis and platelet rich plasma (PRP) injections are usually employed to improve TMJ symptoms and function in these cases. AIMS To compare PRP with arthrocentesis for evaluating the effectiveness of PRP in relieving symptoms of refractory TMJ pain dysfunction syndrome. SETTING AND DESIGN A clinical study was carried out on 52 patients of refractory Temporomandibular joint dysfunction syndrome. The patients were divided in two groups that is Group A - test group and Group B -control Group. METHODS AND MATERIAL Group A consisted of 26 patients who underwent intraarticular PRP injection in TMJ and Arthrocentesis of TMJ was done in 26 patients of Group B. TMJ pain, Maximium Interincisal opening and TMJ clicking were assessed among the group as well as between the groups over a period of 6 months. STATISTICAL ANALYSIS USED Repeated Measure ANOVA was used to compare the parameters within the groups and T test was used for group comparison at 0.05 level of significance. RESULT There was statistically significant difference in pain intensity improvement 1 ± 0.75 versus 3.17 ± 2.13, maximum interincisal opening 39.86 ± 2.86 versus 37.59 ± 4.03 and clicking 6 versus 16 between the PRP group and arthrocentesis group at P < 0.05. CONCLUSIONS Intraarticular PRP injection for the management of refractory TMD is more effective than arthrocentesis in reducing symptoms and functional improvement.
