Masticatory Muscle Activity

The aim of the present study was to analyze novel functional indices of masticatory muscle activity and compare them to existing and commonly used indices in patients with temporomandibular disorders (TMDs) and healthy adults. Based on the Research Diagnostic Criteria for Temporomandibular Disorders, 78 adult women qualified for the study. Subjects were divided into two groups: diagnosed TMDs (n = 36; mean age: 23.4 ± 2.6 years) and healthy adults (n = 42; mean age: 22.4 ± 2.3 years). Measurements of the bioelectric activity of the temporalis anterior (TA), superficial masseter (MM), and anterior bellies of the digastric muscle (DA) were carried out using the BioEMG III ™. Functional Clenching (FCI) and Functional Opening (FOI) indices were obtained as the ratio of the difference between the mean muscle root mean square (RMS) potentials during functional activity, including clenching (CL) and opening (MMO), and mean muscle resting (REST) potentials. Next, based on FCI and FOI indices, the Functional Clenching Activity Index (FCAI), Functional Clenching Symmetry Index (FCSI), and Functional Opening Symmetry Index (FOSI) were obtained. The statistical analysis showed significant differences in activity index left-sided (AcIL) and Activity index both-sided (AcItot) between TMDs and healthy women during rest measurements. The significant differences between both groups were noted in terms of all Functional Clenching Indices except Functional Clenching Index for MM right-sided (FCIMM-R). In all analyzed FCI indices, the control group showed higher values compared to the TMDs. Moreover, a significant difference between TMDs and controls was observed within Functional Clenching Activity Index left-sided (FCAIL) (14.56 vs. −0.45, p = 0.01). Both functional indices, and asymmetry (AsI) and activity (AcI) indices seem to be reliable in assessing symmetry and activity within masticatory muscles. Further studies should be performed to verify the effectiveness and suitability of the assessment of masticatory muscles using functional indices.

Zusammenfassung Hintergrund Kraniomandibuläre Dysfunktionen (CMD) können auch im hohen Alter auftreten. Die Prävalenz von CMD-Symptomen bei Senioren wurde bisher nur wenig untersucht. Ziel der Arbeit Ziel dieser Untersuchung war es, die Prävalenz von Symptomen einer CMD bei Senioren nach Befunderhebung mit den Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) zu bestimmen. Dabei sollten die Prävalenzwerte von jüngeren (60 bis 74 Jahren) und älteren (≥ 75 Jahre) Senioren verglichen werden. Material und Methoden Im Rahmen der Interdisziplinären Längsschnittstudie des Erwachsenenalters (ILSE) wurden Probanden nach repräsentativen Gesichtspunkten rekrutiert. Während der vierten Nachverfolgungswelle im Zeitraum von 2014 bis 2016 im Bereich des Studienzentrums Leipzig wurden die Probanden auf das Vorliegen von anamnestischen und klinischen CMD-Symptomen untersucht. Ergebnisse Anamnestische CMD-Symptome bei Senioren (n = 192) waren v. a. durch Schmerzen im Gesichtsbereich (13,0 %) gekennzeichnet. Das häufigste klinische CMD-Symptom waren Kiefergelenkgeräusche mit einer Prävalenz bis zu 35,5 %. Frauen gaben anamnestisch häufiger Kopfschmerzen/Migräne an. Kiefergelenkgeräusche und eine limitierte Mundöffnung wurden klinisch häufiger bei weiblichen Teilnehmenden beobachtet. Statistisch signifikante Unterschiede zeigten sich bei dem Vergleich von jüngeren und älteren Senioren hinsichtlich der Prävalenz von Kopfschmerzen/Migräne, jedoch nicht bei klinischen Symptomen. Schlussfolgerung Anamnestisch werden Gesichtsschmerzen von 13,0 % der Senioren angegeben. Kiefergelenkgeräusche werden bei jedem dritten Älteren klinisch beobachtet. CMD-Symptome scheinen bei jüngeren und älteren Senioren im ähnlichen Maße ausgeprägt zu sein.

Introdução: A Disfunção Temporomandibular (DTM) é um quadro patológico que afeta o sistema estomatognático e, frequentemente, acompanhada de dor. Objetivos: Aferir o nível de dor dos pacientes portadores de DTM e a prevalência de sintomatologia articular e muscular. Percebeu-se que a relação entre a origem da DTM e a sintomatologia dolorosa é pouco relatada na literatura. Materiais e Métodos: Trata-se de um estudo descritivo, observacional de corte transversal, desenvolvido com 30 pacientes com DTM, diagnosticado pelo Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). A amostra foi determinada pelas estimativas de atendimento. A associação entre a sintomatologia e a origem da DTM foram verificadas através do teste qui-quadrado, com intervalos de confiança (95%). Foi usada uma ficha clínica para a coleta de dados com idade, gênero e nível da dor, que foi aferido através da Escala Visual Analógica de dor. Resultados: Constatou-se que 26 pacientes eram do sexo feminino e 4 do sexo masculino. Quinze apresentaram idade inferior a 36,5 anos, e os outros uma idade superior a esta. Quanto a origem da DTM, 19 tinham desordem articular e 11 muscular. A categoria moderada foi o nível mais prevalente, seguida do intenso. Determinou-se que não houve associação estatisticamente significante entre as variáveis deste estudo com a DTM. Conclusão: Constatou-se que, os fatores etiológicos analisados isoladamente não influenciam de forma única no desenvolvimento da DTM, mas poderão atuar em conjunto com outros fatores, já que a sua causa é multifatorial.Descritores: Dimensão Vertical; Boca Edêntula; Dor Facial; Síndrome da Disfunção da Articulação Temporomandibular.ReferênciasDworkin SF, LeResche L.

Aim:To investigate the prevalence of otolaryngological symptoms with Temporomandibular Disorders (TMD) in TMD patients. Materials and Methods: In this cross sectional study, the sample consisted of 172 TMD patients, both males and females of 18-59 years. Diagnosis of TMD was based on Research Diagnostic Criteria for TMD (RDC-TMD) Axis 1. The prevalence of otolaryngological symptoms was determined using questionnaire. Results: Of the 172 TMD patients evaluated, 81 patients were having Muscular disorder alone or combined with Intracapsular disorder. Out of the 81 patients having muscular disorder, 74 had ear symptoms (91.4%). Conclusion: A high prevalence (91.4%) of Otolaryngological symptoms with TMD was found in the present study. Ruling out causes of ear symptoms other than TMD by an ENT specialist is essential before proceeding with the treatment of these category of patients for a better prognosis.
