Conclusiones: Existen estudios que relatan asociación entre el bruxismo y las disfunciones temporomandibulares en niños de 3 a 12 años, relacionando la presencia de signos y síntomas de la DTM con el bruxismo, pudiendo ser este último, un factor de riesgo para la presencia de DTM.

ABSTRACT Introduction: Bruxism is defined as an oral motor activity that consists of involuntary clenching or grinding (non-functional rhythmic or spasmodic) of the teeth, with a prevalence rate ranging from 5.9% to 49.6% in children, which could contribute to clinical problems associated with the temporomandibular joint. The association between bruxism in children and temporomandibular dysfunction (TMD) is not yet fully established. Objective: The objective of this literature review is to collect up-to-date information on studies that have addressed the association between bruxism and temporomandibular dysfunction in children ranging 3 - 12 years of age. Methods: A search was performed in the Scopus, PubMed and SciELO databases using the descriptors "Child", "Children", "Child, Preschool", "Bruxism", "Sleep Bruxism", "Temporomandibular Dysfunction" and "Temporomandibular Joint Dysfunction Syndrome." Articles published in the last 15 years in the Spanish, English and Portuguese languages were included. Results: A total of seventy-two articles were assessed. Only 11 articles were included according to the inclusion criteria. Among the included studies, two of them found no association between TMD and bruxism, three found a trend or probable association, and six found a positive association. Conclusion: There are studies that report an association between bruxism and temporomandibular dysfunctions in children ranging 3 - 12 years old, relating the presence of signs and symptoms of TMD with bruxism.

Carboxytherapy for the elimination of pain symptoms (or arthralgia) among the elderly persons with the pathology of the temporomandibular joint.

Temporomandibular arthralgia is difficult to treat, painful and often relapses. 48 patients (19 men and 29 women) aged 61-72 years, suffering from the syndrome of pain dysfunction of the temporomandibular joint, were under observation. In 1st (control) group of patients (18 people), NSAIDs indomethacin in tablet form of 25 mg 3 times a day were used for 9 days. In patients of the 2nd (main) group (30 people), the method of invasive carboxytherapy was used, consisting in subcutaneous injection of carbon dioxide with a volume of 3 ml of 5 procedures every other day. On the 3rd, 9th and 15th days of follow-up, invasive carboxytherapy was more effective than the use of a nonsteroidal anti-inflammatory agent by 8.9; 36,5 and 37%, respectively. The high efficiency of the method of invasive carboxytherapy for the elimination of pain symptoms in pain dysfunction was shown, which was 22,86% on day 3; 64,29% on day 9 and 68,16% on day 15 of observation. The method of invasive carboxytherapy can be used in the complex treatment of patients with pain dysfunction of the temporomandibular joint.

Introduction: Temporomandibular disorders (TMD) is a highly underreported health problem. In addition, its diagnosis is complex and requires the use of valid and reliable instruments for use in epidemiological studies. Objective: To validate the Epidemiological Diagnostic Instrument for TMD (EDI/TMD), with applicability for national epidemiological studies. Methodology: This is a validation study, internal structure validity through Exploratory Factor Analysis (EFA), reliability (internal consistency, interobserver and intraobserver), and convergent validity of the EDI/TMD were assessed using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) as the gold standards. The sample was composed of 221 volunteers, 120 in the EFA stage, 50 for the test-retest, and 101 for convergent validity. Results: AFE showed three factors (Muscles TMD, Joint TMD, and Differential Diagnosis) with all items having factor loadings > 0.4, which explained 73.3% of the total variance. Good internal consistency with Cronbach's alpha= 0.775. Reliability ranged from substantial to excellent, reproducibility interobserver (Kappa=0.74-1.00, ICC=0.91-0.97; p< 0.001) and intraobserver (Kappa= 0.75-1.00, ICC=0.80-0.98; p< 0.001). The EDI/TMD total score showed valid and satisfactory diagnostic criteria according to the DC/TMD (Kappa= 0.906; p<0.001), with the ability to differentiate between individuals without and with TMD with a cut-off point of 4.9 (Sensitivity=1.0; Specificity=1.0; AUR=1.0); Mixed TMD with a cut-off point of 14 or more (Sensitivity=0.8; Specificity=1.0; AUR=0.987); and either Muscles TMD (Sensitivity=1.0; Specificity= 0.88; PPV= 0.89; NPV=1.0) or Joint TMD (Sensitivity=0.95; Specificity= 0.87; PPV= 0.83; NPV=0.96), with a cut-off point between 5-13.9, with the diagnosis obtained from the highest score in each factor (Muscles or Joint). Conclusion: The EDI/TMD is a valid and reliable assessment tool, with adequate and satisfactory psychometric properties, capable of diagnosing people with TMD and classifying the subtype of the condition (Muscles, Joint, and Mixed) (AU).

Prevalence of Temporomandibular Disorders and its Correlation with Stress and Salivary Cortisol Levels among Students

ABSTRACT Objective: To evaluate the prevalence of temporomandibular disorders (TMD) in students and to evaluate if any relationship existed between the stress levels, salivary cortisol levels, and TMD. Material and Methods: A total of 348 students, 187 female, and 161 male students, participated in this cross-sectional study. Students were evaluated based on the Research Diagnostic Criteria for TMD. The stress levels were evaluated using the Perceived Stress Scale. The students were divided into the control and TMD groups. Salivary cortisol levels in the salivary samples were analyzed. Results: The prevalence rate of TMDs was 30.7% in the study population. Of the female students, 61% had TMD compared with 46% of male students. Muscle disorders were the most predominant disorder in 14.2% of the students with TMD. The TMD group showed significantly higher salivary cortisol and stress levels than the control group. The TMD group also showed a moderate positive correlation between cortisol and stress levels (p=0.01). Conclusion: The study showed a strong association between salivary cortisol levels, stress, and temporomandibular disorders. Salivary cortisol could be used as a prognostic biomarker for stress while assessing the severity of TMJ problems in stressed individuals.

The effectiveness of stabilization appliance therapy among patients with myalgia.

BACKGROUND: The efficacy of stabilization appliance therapy for masticatory muscle pain is debated. Therefore, there are currently no clear usage standards. We analyzed patient factors influencing its efficacy and characterized masticatory muscle pain subtypes to determine appropriate therapy candidates. METHODS: This case series study recruited patients diagnosed with local myalgia or myofascial pain and used variables related to temporomandibular disorders in the analysis. We used temporary appliance to screen patients for sleep bruxism for 2 weeks. Afterwards, we initiated therapy with stabilization appliances. Efficacy was evaluated via tenderness intensity during muscle palpation and the treatment satisfaction score after 2 months of treatment. RESULTS: We analyzed 62 (91%) patients. Tenderness upon muscle palpation was mitigated in 27 patients. Mitigated tenderness odds ratios were 0.035 for myofascial pain, 0.804 for 15-item Patient Health Questionnaire scores, and 1.915 for facet length. Thirty-nine patients expressed satisfaction; satisfaction odds ratios were 0.855 for 9-item Patient Health Questionnaire scores, 1.606 for facet length, and 4.023 for awake bruxism awareness. CONCLUSIONS: Stabilization appliance therapy is most effective for patients with awake bruxism awareness, local myalgia, long facets, and no psychosocial risk factors.

Hyoid bone syndrome masquerading as temporomandibular joint dysfunction.

Hyoid bone syndrome is a type of cervicofacial pain that is caused by degeneration of the greater cornu of the hyoid at the attachment of the stylohyoid ligament. We report four patients who presented with deep-seated, dull, aching, temporomandibular (TMJ) pain that radiated from the greater cornu of the hyoid bone and did not respond to conservative management. Diagnostic tests included a local anaesthetic block and digital palpation of the greater cornu of the hyoid bone. All four patients responded well to methylprednisolone 40 mg/ml at the greater cornu of the hyoid bone, which resulted in complete resolution of their symptoms. No patients developed postoperative complications. Oral and maxillofacial surgeons involved in the treatment of orofacial pain should consider this less documented condition in their differential diagnosis when treating temporomandibular disorders.

Nondental orofacial pain in dental practices - diagnosis, therapy and self-assessment of German dentists and dental students.

BACKGROUND: Patients with non-dental orofacial pain syndromes will often primarily consult general dentists and other dental specialists. Early and correct diagnosis and therapy is crucial to prevent chronification. METHODS: We assessed the experience of dentists (general dentists and dental specialists; n = 533) and knowledge level of dental students (n = 130) on the diagnosis and treatment of non-dental orofacial pain. We used an anonymized survey containing 14 items with the four main themes (1) prescription patterns, (2) treatment strategies in non-dental orofacial pain, (3) interdisciplinary cooperation, and (4) self-assessment of knowledge as well as post-graduate education. RESULTS: Ninety-two percent of dental students stated that they feel either 'not at all' (56%) or only 'somewhat' (36%) prepared for the diagnosis or treatment of non-dental orofacial pain. Only 23% of the dentists reported 'good' or 'very good' confidence for the diagnosis of non-dental orofacial pain. NSAID were the analgesics of choice when the pain is unspecific (25%) or even neuralgic (10%). Dentists referred patients with non-dental orofacial pain mostly to ENT-physicians (59%), oral and maxillofacial surgeons (54%) or TMD specialists (51%). CONCLUSION: Interdisciplinary pain treatment seems to be well acknowledged, however, with a focus on referral within the community of dental specialists. Dental curricula and post-graduate trainings need to implement the diagnosis and treatment options of non-dental orofacial pain.

Temporomandibular dysfunction

BACKGROUND: Orofacial pain is a common presentation in the primary healthcare setting and temporomandibular dysfunction represents one of the major causes. Its aetiology is multifactorial, caused by both masticatory muscle dysfunction and derangement within the temporomandibular joint. OBJECTIVE: The aim of this article is to provide an overview of temporomandibular dysfunction, its management and referral considerations for general practioners. DISCUSSION: Temporomandibular joint dysfunction affects a large number of adults. Conservative management involving non-pharmacological and pharmacological therapies is effective in the majority of cases.

Predictors of Long-Term Temporomandibular Disorder Pain Intensity: An 8-Year Cohort Study.

AIMS: To investigate, in individuals with pain-related temporomandibular disorder (TMD), the association of long-term pain intensity with baseline health-related quality of life (HRQoL) and jaw functional limitation. METHODS: Of 513 cases with baseline pain-related TMD (masticatory muscle and/or temporomandibular joint [TMJ] pain), 273 were reevaluated after 8 years, and 258 of them had complete baseline data for Jaw Functional Limitation Scale (JFLS) scores and HRQoL measured by the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores of the 12-item Short Form Health Survey and follow-up data for Characteristic Pain Intensity (CPI) from the Graded Chronic Pain Scale. Secondary analyses of existing data quantified the effects of primary (PCS, MCS) and secondary (JFLS) predictors on follow-up CPI by using multivariable linear regression. Sensitivity analyses considered differences between the included participants (n = 258) and those who were not included (n = 255) by using inverse probability weighting. Interactions of baseline predictors with age, sex, and baseline CPI were evaluated using multivariable linear regression. RESULTS: The score for baseline PCS, but not MCS or JFLS, was associated with follow-up CPI (P = .012). One standard deviation (SD = 9.0)-higher baseline PCS score predicted an overall 3.2-point-lower follow-up CPI (95% confidence interval -5.8 to -0.7) after adjusting for age, sex, MCS, JFLS, and baseline CPI scores. However, the effect of PCS score was not uniform: the association between PCS and follow-up CPI scores was statistically significant for participants with baseline CPI ≥ 51.3/100 and clinically significant for participants with baseline CPI ≥ 68.7/100. Adjustment for TMD treatments and sensitivity analyses had negligible effect. CONCLUSION: In participants with moderate to severe baseline TMD pain intensity, higher baseline physical HRQoL predicted lower TMD pain intensity at 8 years follow-up. PCS score could contribute to a multifactorial long-term TMD pain prediction model.

Assessment of Temporomandibular Joint Dysfunction in Patients with Stroke.

GOAL: The aim of this study was to assess temporomandibular joint dysfunction in patients with stroke. MATERIALS AND METHODS: Total of 100 participants, 50 healthy and 50 who had stroke, were recruited into this study. Digital caliper and algometer were used to assess temporomandibular joint range of motion and masticatory muscle pressure pain threshold. Labial commissure angle measurement was used for the assessment of facial paralysis severity. Fonseca questionnaire was used for temporomandibular joint dysfunction assessment and categorization. In addition, dominant mastication shift was measured by the question that asks the pre and poststroke dominant mastication side. FINDINGS: In intergroup comparison, significant decrease was found in all temporomandibular range of motion parameters in favor of stroke group (P < .05). Despite the fact that no significant difference was found between groups for the pain threshold in masticatory muscles except for middle part of the left temporalis muscle, values were higher in healthy group (P > .05). As a result of intergroup examination of labial commissure angle degree, Fonseca questionnaire score, it was found that labial commissure angle and Fonseca questionnaire scores were higher in stroke group (P < .05). Intragroup examination of patients with stroke showed that dominant mastication side shift was seen in patients with stroke (P < .05). CONCLUSION: It was concluded that, temporomandibular joint dysfunction prevalence was higher in stroke group compared with healthy group and use of modalities specific to temporomandibular joint dysfunction treatment would be beneficial.

Multimodal physiotherapy treatment based on a biobehavioral approach for patients with chronic cervico-craniofacial pain: a prospective case series.

The purpose of this prospective case series was to observe and describe changes in patients with chronic cervico-craniofacial pain of muscular origin treated with multimodal physiotherapy based on a biobehavioral approach. Nine patients diagnosed with chronic myofascial temporomandibular disorder and neck pain were treated with 6 sessions over the course of 2 weeks including: (1) orthopedic manual physiotherapy (joint mobilizations, neurodynamic mobilization, and dynamic soft tissue mobilizations); (2) therapeutic exercises (motor control and muscular endurance exercises); and (3) patient education. The outcome measures of craniofacial (CF-PDI) and neck disability (NDI), kinesiophobia (TSK-11) and catastrophizing (PCS), and range of cervical and mandibular motion (ROM) and posture were collected at baseline, and at 2 and 14 weeks post-baseline. Compared to baseline, statistically significant (p < 0.01) and clinically meaningful improvements that surpassed the minimal detectable change were observed at 14 weeks in CF-PDI (mean change, 8.11 points; 95% confidence interval (CI): 2.55 to 13.69; d = 1.38), in NDI (mean change, 5 cm; 95% CI: 1.74-8.25; d = 0.98), and in the TSK-11 (mean change, 6.55 cm; 95% CI: 2.79-10.32; d = 1.44). Clinically meaningful improvements in self-reported disability, psychological factors, ROM, and craniocervical posture were observed following a multimodal physiotherapy treatment based on a biobehavioral approach.

Short clinical examination for temporomandibular symptoms in general practice.

OBJECTIVE: The aims of the study are to assess the reliability of the short clinical examination, and to compare the information gained with a well-known and validated examination, the diagnostic criteria for temporomandibular disorders (DC/TMD). MATERIALS AND METHODS: The study comprises 52 consecutive, newly referred patients at their first visit and examination to an Orofacial Pain and TMD Clinic, 15 years and older, mean age 44 years. The patients first answered three screening questions for reported symptoms. The clinical examination was performed using both the short examination and the DC/TMD and the result was compared. Another group of 40 newly referred patients, with similar inclusion criteria, was examined twice according to the short clinical examination by two examiners, and the inter-examiner variation was studied. The protocol of the short clinical examination is described. RESULT: The overall agreement between the two methods was fairly good to excellent, as was the degree of agreement between repeated examinations and two examiners using the short clinical examination method. The sensitivity and specificity of the short examination for diagnoses were acceptable to high (with DC/TMD as the golden standard). CONCLUSIONS: The short clinical examination has acceptable reliability and, together with three screening questions, provides enough information about the jaw function to decide whether there is a dysfunction.

Disfunciones temporomandibulares y su relación con trastornos de ansiedad en niños: un caso clínico / Temporomandibular joint dysfunctions and their relationship with anxiety disorders in children: report of a clinical case

La presencia de desórdenes temporomandibulares (TTM) en el niño es un tema controversial. Algunos autores sostienen su ausencia en la población infantil; sin embargo, otros han observado signos y síntomas de TTM en poblaciones pediátricas. Nosotros creemos que tales desórdenes pasan inadvertidos con frecuencia por la falta de un examen clínico completo y minucioso que incluya el estudio de la ATM como parte del sistema estomatognático y como revisión rutinaria en la clínica odontopediátrica. Ante las reiteradas consultas que recibimos en la asignatura Odontología Niños de la FOLP, surgió la inquietud de profundizar en el tema y decidimos realizar un trabajo de investigación denominado : "Disfunciones temporomandibulares y su relación con trastornos de ansiedad en una población infantil". El objetivo general de este trabajo fue determinar los signos y síntomas de los TTM y su relación con los distintos niveles de trastornos emocionales en una población infantil, con el propósito de brindar información a odontólogos y odontopediatras acerca de la importancia de realizar un correcto examen clínico de la ATM que nos alerte sobre la posibilidad de aparición de TTM en niños, sin dejar de estar atentos a los miedos o los diferentes grados de ansiedad que los niños pueden desarrollar y que contribuyen en buen grado a agravar o desencadenar el cuadro.

Oral Behaviors and Parafunctions: Comparison of Temporomandibular Dysfunction Patients and Controls.

The aim of this study is to evaluate the frequency of oral behaviors in patients with temporomandibular disorders (TMD) and a control group without TMD.In this baseline case-control study, 260 controls and 260 subjects with TMD completed the oral behaviors checklist defined as a "self-report scale for identifying and quantifying the frequency of jaw overuse behavior" and underwent clinical examinations using the DC/TMJ international examination form (version May 12, 2013). Relationships of oral parafunctions' frequencies between groups were examined. The statistical analysis was performed with IBM SPSS Statistics 23 software.Age and gender distribution in the study groups did not reveal statistical differences (P > 0.05). Multivariate logistic regression analysis was conducted to establish system of independent oral behaviors for prognosis TMD. The stepwise regression analysis demonstrated that very frequent expression of holding, tightening, or tense muscles is associated with 10.83 times (P < 0.05) higher risk of TMD, grinding teeth together during waking hours with 4.94 times (P < 0.05) higher risk, and sustained talking with 2.64 times (P < 0.05) higher risk of TMD. By contrast, it was determined that 3 oral behaviors were less common in the TMD patients compared with the control group: clenching teeth together during waking hours, facing grimaces, and yawning (P < 0.05). The individuals with TMD reported a significantly higher frequency of 10 behaviors (P < 0.05), 3 of which may be regarded as independent risk factors for TMD. In addition, 3 oral behaviors were more frequently observed in the healthy subjects than in the TMD patients.

Is Centric Relation Always the Position of Choice for TMDs? Case Report of How TMD and Airway Dimension May Be Associated.

Centric occlusion (CO) and centric relation (CR) have been controversial topics in dentistry for almost 100 years. The concept of CR emerged due to the search for a reproducible mandibular position that would enable the prosthodontic rehabilitation of patients needing denture treatment. The following case study is unique because of 2 questions. Which mandibular treatment splint position (CR or CO) was appropriate for the initial and eventual final treatment of this patient for her temporomandibular disorder/myofascial pain and dysfunction? Also, how might the mandibular position of CR and CO affect the size and shape of the airway? The airway's size and shape is important as it relates to sleep-disordered breathing and potentially leading to obstructive sleep apnea later in life. The authors believe this is the first case report describing how mandibular position of CR and CO may affect not only TMJ position but also the airway shape and size in three dimensions.

Assessment of treatment response to splint therapy and evaluation of TMJ function using joint vibration analysis in patients exhibiting TMJ disc displacement with reduction: A clinical study.

Context, Aim, and Objectives: Diagnosis of temporomandibular joint (TMJ) disc displacement with reduction (DDR) is difficult. Literature combining different subjective parameters of TMJ function with an objective evaluation of TMJ function using joint vibration analysis (JVA) is limited. Hence, the study was planned to diagnose temporomandibular disorder accurately, to do a subjective and objective evaluation of TMJ function, and to assess the effectiveness of different types of splint therapy over the conventional anterior repositioning appliance (ARA) group. DESIGN: Single-blind, randomized, comparative clinical trial conducted in thirty patients, 18-55 years of age, allocated to three groups, i.e., ARA conventional group, centric stabilization splint (CSS), and Soft splint (SS) groups. SUBJECTS AND METHODS: Preoperative values of comfortable mouth opening (CMO) in mm, maximum mouth opening (MMO) in mm, TMJ clicking and tenderness (grading 0-3), visual analog scale pain score (0-10 cm), and total energy (TE) integral values of both TMJs using JVA were recorded. Postoperative values were taken at the time of delivery of splint at 1st, 2nd, 6th, and 10th week. Statistical Analysis and Results: Intergroup comparison - Kruskal-Wallis test showed no statistically significant difference in CMO, MMO, and TE values of right TMJs among three groups at any point. No significant difference was seen in TMJ clicking and tenderness among groups at any point of time except at 10 weeks and at 2 weeks, respectively, by Chi-square test. Intragroup comparison - Wilcoxon signed-rank test showed the significance of difference (P < 0.05*) in postoperative visits for CMO, MMO, pain score, and TE values. Clinical effect size, extent, consistency, and percentage of cases showing improvement were maximum for CSS group. CONCLUSIONS: The study concludes that the use of JVA for diagnosis along with history and clinical examination increases the accuracy of the diagnosis of DDR. ARA group was used as a conventional treatment option. Although statistically significant difference in pre- and post-treatment values was obtained in all the three groups, CSS group patients showed consistent clinically effective responses and more significant improvement in the subsequent follow-up visits than SS group. Hence, it is advisable to start therapy with CSS splint in TMJ DDR patients to get sooner and effective results without minimum side effects.

Temporomandibular disorder in otolaryngology: systematic review.

BACKGROUND: Temporomandibular disorder poses a diagnostic challenge to otolaryngologists as orofacial pain, headache and otology symptoms are very common in temporomandibular disorder, and mimic a number of otolaryngological conditions. Missed diagnosis of temporomandibular disorder can lead to unnecessary investigation and treatment, resulting in further patient suffering. OBJECTIVES: To review the current literature and propose management pathways for otolaryngologists to correctly differentiate temporomandibular disorder from other otolaryngological conditions, and to initiate effective treatment for temporomandibular disorder in collaboration with other health professionals. METHOD: A systematic review using PubMed and Medline databases was conducted, and data on temporomandibular disorder in conjunction with otolaryngological symptoms were collected for analysis. RESULTS: Of 4155 potential studies, 33 were retrieved for detailed evaluation and 12 met the study criteria. There are questionnaires, examination techniques and radiological investigations presented in the literature to assist with distinguishing between otolaryngological causes of symptoms and temporomandibular disorder. Simple treatment can be initiated by the otolaryngologist. CONCLUSION: Initial temporomandibular disorder treatment steps can be undertaken by the otolaryngologist, with consideration of referral to dentists, oral and maxillofacial surgeons, or physiotherapists if simple pharmacological treatment or temporomandibular disorder exercise fails.
