Pain and temporomandibular disorders in patients with eating disorders

Abstract Orofacial pain and temporomandibular dysfunction may cause chronic facial pain, which may interfere with the emotional state and food intake of patients with eating disorders (ED), such as anorexia nervosa (AN) and bulimia nervosa (BN). Sixty-four patients were assigned to four groups: Group A (AN - restricting subtype): 07; Group B (AN - purging subtype ): 19; Group C (BN): 16; and Group D (control): 22. Complaints of pain are more prevalent in individuals with eating disorders (p<0.004). There are differences between the presence of myofascial pain and the number of hospitalizations (p = 0.046) and the presence of sore throat (p=0.05). There was a higher prevalence of masticatory myofascial pain and complaints of pain in other parts of the body in ED patients; however, there was no difference between ED subgroups. There was no difference in the number of self-induced vomiting between ED patients with and without myofascial pain.

Short-term quality of life change perceived by patients after transition to mandibular overdentures

Abstract The aim of this longitudinal observational study was to evaluate the oral health-related quality of life (OHRQoL) following patient rehabilitation with implant-retained mandibular overdentures (IMO) and to identify the contribution of the different domains to OHRQoL. The Oral Health Impact Profile (OHIP-EDENT), Dental Impact on Daily Living (DIDL), and Geriatric Oral Health Assessment Index (GOHAI) questionnaires were completed twice by 25 patients: after 3 months of rehabilitation with complete dentures (CD) and after 3 months of IMO loading using stud abutments. The evaluation after IMO rehabilitation showed significant improvement in three DIDL domains: appearance (p = 0.011), eating and chewing (p = 0.003), and general performance (p = 0.003). The GOHAI results showed significant differences in two domains: psychosocial (p = 0.005) and pain and discomfort (p = 0.0004). The OHIP-EDENT outcomes showed significant improvements in five domains: functional limitation (p = 0.0001), physical pain (p = 0.0002), physical disability (p = 0.0010), and psychological disability and handicap (p = 0.032). The largest observed effect sizes were close to one standard deviation and were observed in the eating and chewing domain (0.93) of the DIDL; the pain and discomfort domain (0.83) of the GOHAI, and the functional limitation (0.89), physical pain (1.02), physical disability (0.84) domains of the OHIP-EDENT. The percentage of satisfied patients increased in all domains. Self-reported OHRQoL of CD wearers was significantly improved after 3 months of treatment with IMO, especially concerning the functional and pain-related aspects.

Chronicity factors of temporomandibular disorders: a critical review of the literature

Facial pain often persists long after any identifiable organic pathology has healed. Moreover, in a subgroup of patients with temporomandibular disorder (TMD), no treatment is effective. Knowledge of factors associated with persistent pain in TMD could help identify personalized treatment approaches. Therefore, we conducted a critical review of the literature for the period from January 2000 to December 2013 to identify factors related to TMD development and persistence. The literature findings showed that chronic TMD is marked by psychological distress (somatization and depression, affective distress, fear of pain, fear of movement, and catastrophizing) and characteristics of pain amplification (hyperalgesia and allodynia). Furthermore, these factors seem to interact in TMD development. In addition, our review demonstrates that upregulation of the serotonergic pathway, sleep problems, and gene polymorphisms influence the chronicity of TMD. We conclude that psychological distress and pain amplification contribute to chronic TMD development, and that interactions among these factors complicate pain management. These findings emphasize the importance of multidisciplinary assistance in TMD treatment.

Endoscopic sinus surgery in individuals with facial pain due to chronic maxillary sinusitis ? a functional controlled study / Cirurgia endoscópica de seio da face em indivíduos com dor facial devida a sinusite maxilar crônica ? um estudo funcional controlado

Objective: To measure the intra-sinus pressure and the maxillary sinus functional efficiency (MSFE) in individuals with chronic facial pain after conservative or conventional endoscopic maxillary surgery, as well as in controls. Method: Sinus manometry was performed 5 times during inhalation. Results: The resemblance of pressure values comparing those treated with minimally invasive surgery and controls was remarkable, while traditional surgery significantly decreased intrasinusal pressures. The MSFE was 100% in the three tested times for controls, close to that in those submitted to minimally invasive surgery (98.3%, 98.8%, and 98.0%) and significantly impaired after conventional surgery (48.8%, 52.1%, 48.5 %, p<0.01). All patients submitted to minimally invasive surgery remained pain-free after three months of surgery, relative to 46.7% of the submitted to conventional surgery (p<0.05). Conclusion: Minimally invasive sinus surgery is associated with functionality of the chambers that resemble what is found in normal individuals. .

Objetivo: Medir a pressão intrasinusal e a eficiência funcional do seio maxilar (EFSM) em indivíduos com dor facial crônica após cirurgia endoscópica maxilar conservadora ou convencional em comparação a pessoas normais. Método: A manometria do seio foi feita 5 vezes durante a inalação. Resultados: A semelhança entre os valores das pressões comparando aqueles tratados com cirurgia minimamente invasiva e os controles foi notável, enquanto que na cirurgia tradicional houve diminuição significativa das pressões intrasinusais. A EFSM foi 100% nas três vezes testadas nos controles, de modo muito semelhante ao que foi observado naqueles submetidos a cirurgia minimamente invasiva (98,3%, 98,8%, e 98,0%) e significativamente diminuída naqueles submetidos a cirurgia convencional (48,8%, 52,1%, 48,5 %, p<0,01). Todos os pacientes submetidos a cirurgia minimamente invasiva mantiveram-se sem dor três meses depois da cirurgia, comparados a 46,7% naqueles submetidos a cirurgia convencional (p<0,05). Conclusão: Cirurgia minimamente invasiva está associada a funcionalidade das câmaras sinusais que se assemelha ao que é observado em indivíduos normais. .

Tinnitus and temporomandibular disorders: a literature discussion and case report / Zumbido e disfunções temporomandibulares: uma discussão da literatura e relato de caso

Tinnitus describes the sensation of any sound perceived in the head or in the ears without any evidentstimulus. It may be associated with any form of sensorineural hearing impairment but difficulty in hearingis the major determinant of tinnitus, followed by aging and exposure to noise. Somatic tinnitus is a type ofsubjective tinnitus in which the frequency or intensity is altered by body movements such as clenching thejaw, turning the eyes, or applying pressure to the head and neck. This article reviews the literature aboutthe possible etiologic factors associated with tinnitus, including temporomandibular disorders, while alsopresenting a clinical case in which tinnitus could be associated with myofascial pain. Adequate diagnosisand treatment planning of the clinical case are presented and discussed as well.

O zumbido é descrito com uma sensação de qualquer tipo de som percebido na cabeça ou ouvidos sem nenhum estímulo evidente. Pode estar associado com alguma forma de deficiência auditiva neurossensorial, mas a dificuldade de audição é o maior fator determinante do zumbido, seguido do envelhecimento e da exposição a ruídos. O zumbido somático é um tipo de zumbido subjetivo cuja frequência ou intensidade é alterada por movimentos do corpo, como fechamento da mandíbula, movimento dos olhos ou aplicação de pressão na cabeça e pescoço. Este artigo faz uma revisão da literatura sobre os possíveis fatores etiológicos associados ao zumbido,incluindo disfunções temporomandibulares, além de apresentar um caso clínico no qual o zumbido pode ser associado à dor miofascial. O adequado diagnóstico e o plano de tratamento do caso clínico também são apresentados e discutidos.

Relationship between psychological factors and symptoms of TMD in university undergraduate students

Temporomandibular disorders is a collective term used to describe a number of related disorders involving the temporomandibular joints, masticatory muscles and occlusion with common symptoms such as pain, restricted movement, muscle tenderness and intermittent joint sounds. The multifactorial TMD etiology is related to emotional tension, occlusal interferences, tooth loss, postural deviation, masticatory muscular dysfunction, internal and external changes in TMJ structure and the various associations of these factors. The aim of this study was to evaluate the prevalence of the relationship between signs of psychological distress and temporomandibular disorder in university students. A total 150 volunteers participated in this study. They attended different courses in the field of human science at one public university and four private universities. TMD was assessed by the Research Diagnostic Criteria (RDC) questionnaire. Anxiety was measured by means of a self-evaluative questionnaire, Spielberger's Trait-State anxiety inventory, to evaluate students' state and trait anxiety. The results of the two questionnaires were compared to determine the relationship between anxiety levels and severity degrees of chronic TMD pain by means of the chi-square test. The significance level was set at 5%. The statistical analysis showed that the TMD degree has a positive association with state-anxiety (p=0.008; p<0.05) and negative with trait-anxiety (p=0.619; p<0.05). Moreover, a high TMD rate was observed among the students (40%). This study concluded that there is a positive association between TMD and anxiety.

Disfuncao temporomandibular e o termo usado para descrever uma serie de disturbios envolvendo as articulacoes temporomandibulares, musculos da mastigacao e oclusao, com sintomas comuns como dor, restricao de movimento, sensibilidade muscular e ruido articular intermitente. A etiologia da DTM e multifatorial e esta relacionada a tensao emocional, interferencias oclusais, perda de dentes, desvio postural, disfuncao muscular mastigatoria, mudancas internas e externas na estrutura da ATM, e a diferentes associacoes entre esses fatores. O objetivo deste estudo foi avaliar a relacao entre estresse psicologico e sinais de desordem temporomandibular em estudantes universitarios. Um total de 150 voluntarios participaram deste estudo sendo alunos de uma universidade publica e quatro universidades privadas de diferentes cursos da area de ciencias humanas. A avaliacao da DTM foi realizada por meio do questionario Research Diagnostic Criteria (RDC). Para a avaliacao da ansiedade foi aplicado o questionario Ansiedade Traco-Estado de Spielberger. Os resultados dos niveis de ansiedade e dos graus de DTM dos dois questionarios foram comparados pelo teste do qui-quadrado, com nivel de significancia de 5%. A analise estatistica mostrou que o grau de DTM tem relacao positiva para a Ansiedade-Estado (p = 0,008, p <0,05) e negativa para a ansiedade-traco (p = 0,619, p <0,05), alem disso, foi observado alto indice de DTM entre os estudantes (40%). Por meio dos resultados obtidos e analisados neste estudo, concluiuse que havia uma associacao positiva entre DTM e ansiedade.

Desórdenes temporomandibulares. Interfase: ATM; oclusión; disfunción; dolor crónico orofacial / Temporomandibular disorders. Interphase: TMJ; occlusion; dysfunction; chronic orofacial pain

Aunque la demanda de atención está generalmente referida a ruidos en la región de la ATM, alteraciones en el movimiento mandibular y dolor (artralgia o mialgia), la necesidad y prioridad es el dolor, especialmente cuando deviene en cronicidad. Por su acción discapacitante. Uno de los enfoques más modernos en la avanzada del conocimiento es la llamada: modelo "diatesis orgánica-psicosomática" que utiliza la llamada Clasificación Biaxial, el eje 1 son las afecciones orgánicas de los desórdenes temporomandibulares y el eje II se refiere a los factores que actúan en el stress emocional, ya que ambos tipos de causas interactúan, el tratamiento debe realizarse en ambas áreas
