Background: Temporomandibular disorders (TMDs) are a series of disorders that affect the muscles and joint. Symptoms include joint pain, muscle pain, and limitation of mouth opening. One of several multifactorial diseases, temporomandibular dysfunction has mostly been linked to five etiological factors: occlusion, trauma, severe pain stimuli, parafunctional activities, and psychological elements, including stress, anxiety, and depression. The position of the human body as it is displayed in space is referred to as posture. Several nerve pathways regulate posture, and through ligaments, TMD and posture affect each other. The purpose of this study is to evaluate the possible correlation between posture and TMD through a meta-analysis of the literature; Methods: A literature search was performed on PubMed, Lilacs, and Web of science, and articles published from 2000 to 31 December 2022 were considered, according to the keywords entered. The term “temporomandibular disorders” has been combined with “posture”, using the Boolean connector AND; Results: At the end of the research, 896 studies were identified from the search conducted on the 3 engines. Only three were chosen to draw up the present systematic study summarizing the article’s main findings. The meta-analysis showed through forest plot analysis a correlation between posture and TMD Conclusions: This literature meta-analysis showed a correlation between posture and TMD. Nerve pathways probably regulate both body posture and mandibular posture. Further clinical studies will be needed to confirm this hypothesis and to indicate the main conclusions or interpretations.

“…TMDs can also cause headaches, neck pain and ringing in the ears. 20,21 It is a complex condition that can be caused by multiple factors. As a result, there are various tools available to evaluate the severity of the condition, which are divided into anamnestic, clinical and diagnostic criteria.…”

Introduction: While Temporomandibular disorders (TMDs) are not typically considered a primary symptom of Parkinson disease (PD), recent studies have documented a correlation between ageing and TMDs, a cluster of conditions affecting the temporomandibular joint and surrounding musculature, thereby underscoring the potential for an increased frequency of TMDs in the ageing PD population. Objective: The purpose of this review is to systematically evaluate the existing literature on the topic and provide a comprehensive overview of the prevalence of TMDs in patients with PD. Methods: To determine eligibility, we utilised the Population (human subjects), Exposure (PD), Comparator (PD vs non-PD subjects), and Outcomes (TMD) (PECO) model. To conduct this systematic review, we searched for articles published in PubMed, Web of Science and Lilacs from the beginning until April 15, 2023.Results: Three studies were selected. All together they comprised a total of 55 828 subjects, out of which 12 629 were affected by PD or Parkinsonism, and the remaining 43 199 were non-PD subjects matched for age and sex. The study aimed to evaluate the prevalence of TMDs in subjects affected by PD. The results showed that 193/12629 (1.53%) of PD individuals presented with TMD symptoms or were diagnosed with TMD, while 260/43199 (0.6%) of non-PD subjects were diagnosed with the same. The meta-analysis showed that there was a higher TMD prevalence in PD subjects compared to non-PD subjects (RR 1.57; 95% CI: 1.30-1.89). Conclusion:The studies reviewed suggest a possible association between TMD and PD. Further research is needed to clarify the relationship between TMD and PD and to identify possible mechanisms and treatment strategies.

“…Temporomandibular disorders (TMDs) are a heterogeneous group of conditions that affect the temporomandibular joint (TMJ) and the muscles around it. [1][2][3][4][5] They involve about 15% of adults, peaking between 20 and 40 years old 2,4,[6][7][8][9][10][11][12] and can cause a range of symptoms, such as jaw pain or dysfunction, earache, facial pain and headaches.…”

Background Over the past few years, researchers have investigated whether varying menstrual statuses and oestrogen levels could affect the likelihood of temporomandibular disorders (TMDs), with conflicting results. While some studies suggest a potential link between increased oestrogen levels and higher TMD risk, others have found no correlation. It is worth noting that oestrogen levels can impact the structure and function of the temporomandibular joint (TMJ). In the light of these findings, our study seeks to investigate the prevalence of TMDs among pregnant women. Methods We searched in PubMed, Web of Science and Lilacs for articles published from the inception until 20 January 2023. We applied the Population, Exposure, Comparator and Outcomes (PECO) model to assess the document eligibility: (P) Participants: female human subjects. (E) Exposure: pregnancy. (C) Comparison: pregnant women compared to non‐pregnant women in the childbearing age. (O) Outcome: TMDs diagnosis. Only study providing data about the prevalence in both group (pregnant and non‐pregnant) were included. We set the following exclusion criteria: (1) diagnosis of rheumatic diseases or chronic inflammatory disorders (e.g. rheumatoid arthritis, juvenile, idiopathic arthritis, psoriatic arthritis); (2) diagnosis of fibromyalgia; (3) congenital abnormality or neoplastic conditions in the TMJ region; (4) studies including subjects undergoing arthrocentesis or intra‐articular infiltrations; (5) studies including local pressure pain assessment; (6) studies including women in menopause in the control group (7) cross‐over study design; (8) language different from English; (9) full‐ text unavailability (i.e. posters and conference abstracts); (10) studies involving animals; (11) review (topical or systematic) article; (12) case reports/series; (13) studies evaluating TMDs prevalence in subjects not pregnant. The software Review Manager version 5.2.8 (Cochrane Collaboration) was used to perform the pooled analysis. We measured the risk ratio (RR) between the two groups (pregnant and non‐pregnant). Results The included subjects in this review were 440. Among them, 244 were pregnant while the remaining 196 were age matched non‐pregnant women. Among those pregnant 102 presented sign/symptoms of TMD or TMD diagnosis (41.8%) whereas 80 of those not pregnant were diagnosed with (40.8%). The overall effect showed that there was no difference in TMD prevalence between pregnant and non‐pregnant women in childbearing age (RR 1.12; 95% CI: 0.65–1.93), suggesting that pregnant is neither a risk factor nor a protective factor for TMD. Conclusions Overall, we did not find an association between TMD and pregnancy, neither positive nor negative. Further studies on larger samples are needed to clarify our results.
