Efficacy and Safety of Botulinum Toxin in the Management of Temporomandibular Symptoms Associated with Sleep Bruxism: A Systematic Review

Sleep bruxism, characterized by involuntary grinding or clenching of teeth during sleep, poses significant challenges in management due to its potential to induce temporomandibular joint disorders (TMDs) and other related symptoms. The use of Botulinum toxin Type A (BoNT-A), also known as Botox®, has been proposed as a therapeutic intervention. This systematic review aims to evaluate the efficacy and safety of BoNT-A in the management of sleep bruxism, focusing on pain reduction, improvement in jaw function, reduction in bruxism episodes, and the incidence of adverse effects. An exhaustive search was conducted across PubMed, Scopus, and Embase databases up to January 2024, adhering to the PRISMA guidelines. Nine randomized clinical trials (RCTs) involving 137 participants were analyzed for efficacy and safety outcomes. The studies demonstrated a significant reduction in mean pain scores (from 7.1 to 0.2 at 6 months and 1 year post-treatment in one study) and a notable decrease in the number of bruxism events (from 4.97/h to 1.70/h in the BoNT-A group in another study). Additionally, improvements were observed in jaw stiffness and total sleep time. Adverse effects varied but were generally mild and transient, including injection site pain in 20% of participants in one study and cosmetic changes in smile in 15.4% of patients in another. These findings suggest that BoNT-A injections may provide some benefits for treating nocturnal bruxism, potentially reducing TMD symptoms like pain and improving jaw function. However, these findings are preliminary due to variability in study designs and the absence of detailed statistical analysis.

Effectiveness of Occlusal Splint Therapy in Moderating Temporomandibular Joint Disorders With Joint Displacement: A Retrospective Analysis Using Cone Beam Computed Tomography.

Background Temporomandibular joint disorders (TMD) represent a prevalent group of conditions impacting the temporomandibular joint. Among the therapeutic interventions, occlusal splint therapy has gained recognition for its potential to address TMD symptoms, particularly in cases involving joint displacement. Objective This study aims to investigate the effectiveness of occlusal splint therapy in cases of moderate TMD with joint displacement, focusing on changes in condylar position, joint morphology, and patient-reported outcomes. Methods A retrospective analysis was conducted involving 148 participants who underwent occlusal splint therapy between January 2018 and December 2020. Data were collected through cone beam computed tomography (CBCT) imaging for precise assessments of condylar position and joint morphology. Ethical approval was obtained, and participants provided informed consent. Baseline characteristics, medical history, and TMD severity were recorded. Occlusal splint therapy included individualized fabrication, occlusal analysis, adjustments for optimal fit, and prescribed wear schedules. Follow-up included CBCT scans at specified intervals (three months and six months), with participant-reported outcomes collected. The data analysis was conducted using IBM SPSS Statistics for Windows, Version 22.0 (Released 2013; IBM Corp., Armonk, NY, USA). Paired t-tests or nonparametric equivalents were employed to assess changes in condylar position and joint morphology. Subgroup analyses were conducted to explore potential factors influencing treatment outcomes. The significance level was set at p < 0.05 for all statistical tests. Results The entire cohort (n = 148) had a mean age of 32.5 years (± 8.1), with a balanced gender distribution. Changes in condylar position revealed a statistically significant improvement (p = 0.03), with a mean decrease of 0.2 mm posttreatment. Joint morphology changes indicated increased joint space width (p = 0.01), improved disc position (p = 0.02), and nonsignificant alterations in bony structures (p = 0.10). Patient-reported outcomes demonstrated significant improvements in pain levels, jaw functionality, and satisfaction (all p < 0.001). Age and gender subgroup analyses showed consistent improvements in condylar position, joint morphology, and patient-reported outcomes across different groups. Conclusion Occlusal splint therapy demonstrated effectiveness in improving condylar position, joint morphology, and patient-reported outcomes in cases of moderate TMD with joint displacement. The findings underscore the potential of occlusal splint therapy as a viable intervention for managing TMD, providing valuable insights for clinicians and researchers.

Does Liquid/Injectable Platelet-Rich Fibrin Help in the Arthrocentesis Treatment of Temporomandibular Joint Disorder Compared to Other Infusion Options? A Systematic Review of Randomized Clinical Trials.

Temporomandibular joint disorders (TMDs) are prevalent musculoskeletal conditions involving pain and dysfunction of jaw mobility and function, which have proven difficult to treat satisfactorily. The present study aimed to assess the effectiveness of a liquid platelet-rich fibrin (i-PRF) infusion during arthrocentesis versus other options using coadjuvant materials to reduce TMD symptoms. A literature search was conducted using PubMed, EMBASE, Web of Science, Scopus, and ClinicalTrials.gov for RCTs published before January 2024, comparing i-PRF to any other TMD treatment. This systematic review was registered on PROSPERO (CRD42023495364). The searches generated several recent RCTs that compared i-PRF injection combined with arthrocentesis (AC) to AC-only or AC with platelet-rich plasma (PRP). The outcomes analyzed included measures of pain (visual analog scale, VAS), maximum mouth opening, joint sounds, and MRI-verified changes in joint structure. Across the RCTs, the addition of i-PRF injection to AC resulted in significant improvements in pain relief, joint function, mouth opening, and structural changes compared to AC-only or with PRP over follow-up periods ranging from 6 to 12 months. Current clinical evidence favors using i-PRF as an adjunct to AC rather than AC-only or AC with PRP for the treatment of TMDs. The improvements in subjective and objective outcome measures are clinically meaningful. Still, additional high-quality RCTs with larger sample sizes and longer follow-ups are required to strengthen the evidence base and better define the role of i-PRF in TMD management guidelines.

The epidemiological profile of temporomandibular joint disorders in the Tunisian population: A cross-sectional study

ObjectiveThis study aimed to explore the prevalence, signs, and symptoms of different types of TMD (Temporomandibular joint disorders) disorders in Tunisian patients. MethodsA retrospective cross-sectional study was conducted using the clinical records of patients from the Department of Functional Exploration, Pain, and Orofacial Dysfunction of the Dental Clinic of Monastir. ResultsTMD is associated with a female predominance, with a peak prevalence among those aged between 20 and 40 years. Pain and a limited range of motion were significantly more prevalent in women (p = 0.019 and p = 0.012, respectively). Clicking sounds were the most frequent joint noises (38.2 %). Crepitus was more prevalent among older adults (33 %). Of the different types of TMD, disk displacement with reduction was the most prevalent (n = 216, 39 %). Sleep bruxism was more prevalent than awake bruxism (20.7 % VS 9.5 %). Due to the heterogeneous TMD signs and symptoms, patients tend to seek medical attention from various specialties (e.g. neurology and otolaryngology). ConclusionThe prevalence of different types of TMD, and the different signs and symptoms varied depending on sociodemographic characteristics, such as sex, age and lifestyle. Diagnosis is challenging and TMD may be confused with other orofacial pain conditions.

Applications of hydrogels in tissue-engineered repairing of temporomandibular joint diseases.

Epidemiological studies reveal that symptoms of temporomandibular joint disorders (TMDs) occur in 60-70% of adults. The inflammatory damage caused by TMDs can easily lead to defects in the articular disc, condylar cartilage, subchondral bone and muscle of the temporomandibular joint (TMJ) and cause pain. Despite the availability of various methods for treating TMDs, few existing treatment schemes can achieve permanent recovery. This necessity drives the search for new approaches. Hydrogels, polymers with high water content, have found widespread use in tissue engineering and regeneration due to their excellent biocompatibility and mechanical properties, which resemble those of human tissues. In the context of TMD therapy, numerous experiments have demonstrated that hydrogels show favorable effects in aspects such as articular disc repair, cartilage regeneration, muscle repair, pain relief, and drug delivery. This review aims to summarize the application of hydrogels in the therapy of TMDs based on recent research findings. It also highlights deficiencies in current hydrogel research related to TMD therapy and outlines the broad potential of hydrogel applications in treating TMJ diseases in the future.

Orthodontic treatment of an open bite after splint therapy for a patient with idiopathic condylar resorption

In the treatment of orthodontic patients with idiopathic condylar resorption, symptoms of temporomandibular joint disorders and constantly changing occlusions caused by an instability of mandibular position make it difficult for orthodontists to confirm definitive orthodontic diagnosis and treatment plans. Therefore, these patients' temporomandibular joint (TMJ) structures need to be stabilized with splint therapy before active tooth movement to identify and maintain the true mandibular position. For some idiopathic condylar resorption patients, orthognathic surgery can cause further resorption on the vulnerable condyles of the mandible; thus, effective orthodontic camouflage treatment after joint stabilization should be considered. During the orthodontic camouflage treatment, adverse loads on the TMJ structures, which could change the position of condyles, should be avoided, and TMJ-friendly mechanics must be applied.

Investigating the Association between Obstructive Sleep Apnea and Temporomandibular Joint Disorders: A Case-Control Study.

This study aims to explore the connection between obstructive sleep apnea (OSA) and temporomandibular joint disorders (TMD) through a case-control investigation. OSA is a sleep-related breathing disorder that affects breathing during sleep, whereas TMD involves pain and dysfunction in the jaw joint. Understanding any potential association between these two conditions could contribute to improved diagnostic and therapeutic approaches. A total of 50 participants were included in both the OSA group and the control group. Participants with diagnosed OSA constituted the OSA group, whereas individuals without OSA formed the control group. TMD symptoms were assessed using standardized diagnostic criteria. Statistical analysis was performed to compare the prevalence of TMD symptoms between the two groups. In the OSA group, 36 out of 50 participants exhibited TMD symptoms, whereas in the control group, 18 out of 50 participants displayed such symptoms. The calculated P value was found to be 0.023, indicating a statistically significant association between OSA and TMD. The findings of this study suggest a notable association between OSA and TMD. Individuals with OSA are more likely to experience TMD symptoms compared to those without OSA. This underscores the importance of considering TMD symptoms in individuals with OSA and vice versa for a comprehensive approach to diagnosis and management.

Prevalence of signs and symptoms of temporomandibular joint disorders and associated factors among Iranian dental student

Introduction: Temporomandibular disorders include a number of clinical signs and symptoms that involve the muscles, temporomandibular joint, and teeth. The aim of this study was to investigate the prevalence of signs and symptoms of temporomandibular joint disorders in dental students of Golestan University of Medical Sciences in the academic year 1400-1401. Method: In this study, 193 dental students were selected from the population under study by available sampling method. First, the necessary information was collected through interviews and completing the checklist. Male and female students were randomly selected and were subjected to a complete examination in terms of the health of the temporomandibular joint. After data entry in SPSS software version 19, the data was described with the help of frequency and percentage and chi-score test. A significance level of 0.05 was considered. Results: 193 students participated in this study, of which 98 were male and 95 were female. There were 30 first-year students, 30 second-year students, 39 third-year students, 32 fourth-year students, 26 fifth-year students, and 36 sixth-year students. The average age of the students was 24.5 years. Occlusion of class 1, class 2 and class 3 was seen in 156 people (80.8%), 29 people (15%) and 8 people (4.1%), respectively. A history of trauma to the jaw was reported in 14 people (7.3%). 17 people (8.8%) mentioned headache. Bruxism was observed in 13 people. The results of chi square test showed that there was no statistically significant relationship between related variables to TMJ disorder and gender. Conclusion: Considering the relatively high prevalence of temporomandibular joint disorder among dental students, further studies are recommended to investigate other related factors.

Investigating the effect of obsessive-compulsive disorder on clinical symptoms of temporomandibular joint disorders.

Temporomandibular disorders (TMD) are a group of clinical conditions involving muscles of mastication, temporomandibular joint (TMJ), and related structures or both. TMD is characterized by facial pain in TMJ and muscles of mastication, limitation or deviation of jaw movement, and TMJ sounds during jaw movement and function. The highest risk of TMD prevalence is between 18 and 24 years, and a relationship is between chronic TMD and psychological disorders such as stress and depression. The knowledge of the function of this joint and those with TMD symptoms when visiting the dentist will help to provide an ideal treatment plan for the patient. Therefore, if the therapist is familiar with the various etiological factors of this disorder, he will provide better treatment, especially if the simultaneous effect of psychological factors such as stress and obsessive-compulsive disorder (OCD) along with occlusal factors such as posterior cross-bite, overjet, and overbite is measured, it can be a valuable guide for clinicians. In this study, 385 patients were examined by DASS42 and Maudsley's test and classified into normal, with stress, and stress plus OCD groups. TMJ was examined for each of them by the TMD-RDC test. The presence or absence of TMD was noted in their file. The prevalence of TMD was 20.7% in the normal group, 30.70% in the stress group, and 44.68% in the stress and OCD group. After analyzing the data by SPSS 24 and performing analysis of variance and Duncan tests, no significant difference was found between the probability of TMD in normal and stressed groups, but the stress and OCD group has a higher chance of TMD. Although the co-occurrence of stress and OCD is associated with the prevalence of TMD, it cannot be considered a cause of TMD.

Correlation between mental well-being and severity of class II temporomandibular joint disorders, compared to non-temporomandibular joint disorders

Temporomandibular joint disorders (TMDs) are one of the most common ailments encountered in the craniofacial region, with various clinical, radiological and psychological manifestations but often go undiagnosed due to lack of a diagnostic protocol to assess and correlate all these factors in order to create an effective management plan based on early diagnosis. The objectives of this research are to assess, compare and co-relate the severity of clinical and radiological findings with mental well-being in class II (vertical growth pattern) TMD cases as compared to class I non-TMD cases. Grading of skeletal class II cases on the severity of TMD will be done using Diagnostic Criteria for TMDs (DC/TMD). Bilateral sagittal as well as coronal magnetic resonance imaging (MRI) images will be obtained. Evaluation and grading of mental well-being and anxiety will be done using the Warwick-Edinburgh and Hamilton scales, respectively. The expected results are a probable positive correlation between the severity of clinical and radiological symptoms of TMDs and deteriorating mental well-being in the form of stress, anxiety and depression. A cause-effect relationship may be evaluated with the aim of early diagnosis and management of TMDs as improving the quality of life of these cases. This study will aid in identifying the clinical symptoms and articular disc position on MRI as they correlate with the mental well-being status and anxiety levels in TMD cases. Further management and early intervention can be undertaken in such cases to prevent or stall the progression of TMD into severe forms while improving the quality of life (QoL) in such cases.

DIFFERENCES IN THE PREVALENCE OF SYMPTOMS OF TEMPOROMANDIBULAR JOINT DISORDERS IN FACULTY OF DENTISTRY UNIVERSITAS JENDERAL ACHMAD YANI STUDENTS

Temporomandibular joint disorder (TMD) is a common problem with various clinical signs and symptoms of the structures of the masticatory system, including the masticatory muscles and the temporomandibular joint, often found in the age group of 20-40 years. People with TMD symptoms can show at least one symptom of the disorder. The prevalence of TMD was reported among dental students. This study aims to determine differences in the majority of symptoms of temporomandibular joint disorder in students of the Faculty of Dentistry, Jenderal Achmad Yani University class of 2020 in 2021 and 2023.

Comparative analysis of craniofacial asymmetry in subjects with and without symptoms of temporomandibular joint disorders: a cross-sectional study.

The aim of the study was to quantify and compare craniofacial asymmetry in subjects with and without symptoms of temporomandibular joint disorders (TMDs). A total of 126 adult subjects were categorized into two groups (63 with a TMDs and 63 without a TMDs), based on detection of symptoms using the Temporomandibular Joint Disorder-Diagnostic Index (TMD-DI) questionnaire. Posteroanterior cephalograms of each subject were traced manually and 17 linear and angular measurements were analyzed. Craniofacial asymmetry was quantified by calculating the asymmetry index (AI) of bilateral parameters for both groups. Intra- and intergroup comparisons were analyzed using independent t-test and Mann-Whitney U test, respectively, with a P<0.05 considered statistically significant. An AI for each linear and angular bilateral parameter was calculated; higher asymmetry was found in TMD-positive patients compared with TMD-negative patients. An intergroup comparison of AIs found highly significant differences for the parameters of antegonial notch to horizontal plane distance, jugular point to horizontal plane distance, antegonial notch to menton distance, antegonial notch to vertical plane distance, condylion to vertical plane distance, and angle formed by vertical plane, O point and antegonial notch. Significant deviation of the menton distance from the facial midline was also evident. Greater facial asymmetry was seen in the TMD-positive group compared with the TMD-negative group. The mandibular region was characterized by asymmetries of greater magnitude compared with the maxilla. Patients with facial asymmetry often require management of temporomandibular joint (TMJ) pathology to achieve a stable, functional, and esthetic result. Ignoring the TMJ during treatment or failing to provide proper management of the TMJ and performing only orthognathic surgery may result in worsening of TMJ-associated symptoms (jaw dysfunction and pain) and re-occurrence of asymmetry and malocclusion. Assessments of facial asymmetry should take into account TMJ disorders to improve diagnostic accuracy and treatment outcomes.

Relationship of Temporomandibular Joint Disorders and Psychological Distress in Young Adults

Background: Temporomandibular disorders (TMD) relate to dysfunctions that impact the temporomandibular joint (TMJ), masticatory muscles, and connected structures. Psychological well-being can be among the various factors that TMD affects. Prior studies conducted in different countries have demonstrated a correlation between TMD symptoms and psychological distress in young adults. However, research on this topic is limited in Indonesia. Objective: To assess the association of symptoms of temporomandibular joint disorder and psychological stress in young adults. Materials and Methods: This research employed an analytical cross-sectional design and involved 354 participants (141 males and 213 females) aged 19-21 from Kampus A of Universitas Trisakti. The subjects' general characteristics, including gender, age, and ethnicity, were described. The data were gathered through two types of questionnaires: DC/TMD axis I (Symptom Questionnaire) and axis II (Patient Health Questionaire-PHQ-4), and were analyzed using the Spearman correlation test administered through Google Form. Result: The study's findings revealed that 141 participants (39.8%) were male, while 213 (60.2%) were female. Among the research subjects, 91 individuals - 32 males and 59 females - experienced the most discomfort in the pain category, with the mean PHQ-4 score for pain being the highest at 4.68. The bivariate analysis demonstrated a moderate correlation coefficient value (r = 0.401) and a significant relationship (p 0.05) between temporomandibular disorders (TMD) in the pain category and psychological distress. The prevalence of TMD was 39.8% in males and 60.2% in females. Conclusions: TMD is a common problem among young adults aged 19-21 years, and pain associated with TMD can lead to psychological distress in this age group.

Prevalence of Clinical Signs and Symptoms of Temporomandibular Joint Disorders Registered in the EUROTMJ Database: A Prospective Study in a Portuguese Center.

Temporomandibular joint disorders (TMDs) are characterized by their multifactorial etiology and pathogenesis. A 3-year prospective study was conducted in a Portuguese TMDs department to study the prevalence of different TMDs signs and symptoms and their association with risk factors and comorbidities. Five hundred ninety-five patients were included using an online database: EUROTMJ. Most patients were female (80.50%), with a mean age of 38.20 ± 15.73 years. The main complaints were: (1) temporomandibular joint (TMJ) clicking (13.26%); (2) TMJ pain (12.49%); (3) masticatory muscle tension (12.15%). The main clinical findings were myalgia (74%), TMJ clicking (60-62%), and TMJ arthralgia (31-36%). Risk factors such as clenching (60%) and bruxism (30%) were positively associated with TMJ pain and myalgia. Orthodontic treatment (20%) and wisdom tooth removal (19%) were positively associated with TMJ clicking, while jaw trauma (6%), tracheal intubation (4%) and orthognathic surgery (1%) were positively associated with TMJ crepitus, limited mandibular range of motion, and TMJ pain, respectively. In total, 42.88% of TMDs patients had other associated chronic diseases, most of them were mental behavioral or neurodevelopmental disorders (33.76%), namely, anxiety (20%) and depression (13%). The authors also observed a positive association of mental disorders with the degree of TMJ pain and myalgia. The online database seems to be a relevant scientific instrument for healthcare providers who treat TMDs. The authors expect that the EUROTMJ database can serve as a milestone for other TMDs departments.

Longitudinal trends in temporomandibular joint disorder symptoms, the impact of malocclusion and orthodontic treatment: A 20-year prospective study.

Studies on the association between malocclusion and temporomandibular joint disorder (TMD) have reported conflicting results. To determine the impact of malocclusion and orthodontic treatment on symptoms of TMD. At 12 years, 195 subjects fulfilled a questionnaire regarding TMD symptoms and participated in an oral examination including preparation of dental casts. The study was repeated at ages 15 and 32. The occlusions were assessed by applying the Peer Assessment Rating (PAR) Index. Associations between the changes in PAR scores and TMD symptoms were analysed with the chi-square test. A multivariable logistic regression was used to calculate the odds ratios (OR) and 95% confidence intervals (CI) of TMD symptoms at 32 years predicted by sex, occlusal traits and orthodontic treatment history. One in three subjects (29%) was orthodontically treated. Sex was associated with more self-reported headaches by females at 32 years (OR 2.4, 95% CI 1.05-5.4; p = .038). At all time points, any crossbite was significantly associated with greater odds for self-reported temporomandibular joint (TMJ) sounds at 32 years (OR 3.5, 95% CI 1.1-11.6; p = .037). More specifically, association occurred with posterior crossbite (OR 3.3, 95% CI 1.1-9.9; p = .030). At 12 and 15 years, boys whose PAR score increased were more likely to develop TMD symptoms (p = .039). Orthodontic treatment had no impact on the number of symptoms. Presence of crossbite may increase the risk of self-reported TMJ sounds. Also, longitudinal changes in occlusion may have an association with TMD symptoms while orthodontic treatment is not associated with the number of symptoms.

Impact of different types of temporomandibular disorders on jaw functional limitation and psychological distress in orthodontic patients.

Some orthodontic patients are associated with temporomandibular joint disorders (TMDs), and the differences between jaw function and psychological states in orthodontic patients with different types of TMDs remain unknown. This cross-sectional study aimed to investigate the prevalence of different types of TMDs in orthodontic patients and to evaluate the relationship between different types of TMDs and jaw functional limitation and psychological distress in orthodontic patients. A questionnaire was sent to patients willing to participate in this survey, which included questions about the demographic characteristics of the participants, the five TMD symptoms (5Ts) of the Diagnostic Criteria for TMDs, the Jaw Functional Limitation Scale-8 (JFLS-8) and the Patient Health Questionnaire for Depression and Anxiety (PHQ-4). The subjects were divided into three groups: painful TMDs (PT), non-painful TMDs (NPT), and TMD-free according to whether they had TMDs and its subtypes. A total of 670 valid questionnaires were collected from 182 males and 488 females. The prevalence of TMDs was 35.4%, of which the prevalence of PT was 11.8% and the prevalence of NPT was 23.6%. The median JLFS-8 score of TMD patients was significantly higher than TMD-free, and PT patients were significantly higher than NPT (p = .026). After adjusting for confounding factors, the jaw function and psychological states of PT patients and NPT patients were worse than those of the TMD-free group. Among the orthodontic patients surveyed, more than one-third had TMDs and the prevalence of PT was lower than NPT. Having TMDs is associated with more severe jaw functional limitation, and PT patients were more serious than NPT patients. At the same time, the psychological states of TMDs patients were also worse.

Temporomandibular joint disorders prevalence and health-seeking preferences among Al-Madinah community: A prospective cross sectional study

Background: Painful temporomandibular joint disorders (TMDs) are of musculoskeletal origin and are considered the most common cause of non-odontogenic pain in the orofacial region. The purpose of this study was to investigate the prevalence and awareness of temporomandibular joint (TMJ) disorders in Almadinah Almunawwarah community. Methods: A prospective observational cross-sectional study with convenience sampling was conducted. The patients were selected from the dental college and the hospital at Taibah University in Al-Madinah, Saudi Arabia. A translated Arabic version of Fonseca's questionnaire was employed. The questionnaire asked about the participant's personal information, if they thought they had TMDs, and who to visit for therapy if necessary. These were followed by 10 items from Fonseca's questionnaire, each with a three-point scale. Results: The questionnaire was completed by 518 people. Females made up 57.1% of the participants. TMDs were present in 61% of the population, with varying degrees of severity. Males (44.3%) were less affected than females (55.7%). The difference, however, was not statistically significant (P = 0.354). Out of the 61% TMDs Positive patients, 74.1% had mild TMDs symptoms, while 20.8% and 5.1%, respectively, had moderate and severe TMDs symptoms (P = 0.05). The severity of the symptoms was unaffected by demographic data (P &gt; 0.05). Only 40% seek care, with 64.6% selecting for a dentist or orofacial pain specialists for their management and 24.6% preferring for an orthopaedic specialist (P= 0.008). Conclusions: Participants from Al-Madinah had a greater prevalence of mild TMDs. The majority of the participants had no idea who to go to for treatment. The findings of this study highlight the importance of educational activities to enhance public awareness

Relationship assessment between mood disorders, headaches, and temporomandibular disorders in healthcare workers post-COVID-19 pandemic

Objectives: To evaluate the relationship between depression, anxiety, and stress levels, headaches, and symptoms of temporomandibular joint disorders in healthcare professionals in a post-pandemic setting. Methods: A cross-sectional study conducted through an online questionnaire was distributed among healthcare professionals in Mainland Portugal. The sample’s characterization was undertaken according to sociodemographic parameters. The following assessment instruments were used: 21-item Depression, Anxiety, and Stress Scale (DASS-21) for emotional parameters, namely depression, anxiety, and stress; International Classification of Headache Disorders (ICHD-3) for headache disorders; Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for temporomandibular joint dysfunction symptoms. Inferential analysis was performed using phi, Cramer’s V, and gamma tests. Results: The sample comprised 118 individuals (93.2% female, 6.8% male). Results showed a prevalence of 38.1% for depression, 51.7% for anxiety, and 39.8% for stress. Regarding headaches, a prevalence of 62.7% was reported. Symptoms of temporomandibular disorders had a prevalence of 50%. Significant differences were found between headache and stress (p=0.034), headache and temporomandibular joint disorders symptoms (p=0.002), and symptoms of temporomandibular disorders and depression (p=0.009), anxiety (p=0.003), and stress levels (p=0.014). Conclusions: There seems to be a positive correlation between headaches and stress levels, between temporomandibular disorders symptoms and all psychosocial parameters, and between temporomandibular disorder symptoms and headaches. Data suggests that these symptoms worsened after the pandemic.

Focus Groups to Inform the Development of a Patient-Reported Outcome Measure (PROM) for Temporomandibular Joint Disorders (TMDs).

Understanding symptoms of temporomandibular joint disorders (TMDs) can help doctors and patients document, monitor, and manage the disease and help researchers evaluate interventions. Patients with TMDs experience symptoms ranging from mild to severe, primarily in the head and neck region. This study describes findings from formative patient focus groups to capture, categorize, and prioritize symptoms of TMDs towards the development of a patient-reported outcome measure (PROM). We conducted ten focus groups with 40 men and women with mild, moderate, and severe TMD. Focus groups elicited descriptions of symptoms and asked participants to review a list of existing patient-reported outcomes (PROs) from the literature and patient advisor input and speak to how those PROs reflect their own experience, including rating their importance. We identified 52 distinct concepts across six domains: somatic, physical, social, sexual, affective, and sleep. Focus groups identified the ability to chew and eat; clicking, popping, and other jaw noises; jaw pain and headaches; jaw misalignment or dislocation; grinding, clenching, or chewing, including at night; and ear sensations as most important. Participants with severe TMDs more often reported affective concepts like depression and shame than did participants with mild or moderate TMDs. Findings support PROM item development for TMDs, including selecting existing PROMs or developing new ones that reflect patients' lived experiences, priorities, and preferred terminology. Such measures are needed to increase understanding of TMDs, promote accurate diagnosis and effective treatment, and help advance research on TMDs.
