Temporomandibular Disorders in Violinists of Alliance Violin Community Bandung

@#Introduction: Technique of playing violin requires violinist to adjust the instrument on their left shoulder while the mandible helps holding it. The outcome is continuous mechanical force to area of craniofacial and neck. This force can induce temporomandibular disorders (TMD). The aim of this research was to obtain the description of diagnosis of TMD in violinists of Alliance Violin Community Bandung. Methods: This was a descriptive research. The subjects for this research were (n=34) violinists who became the members of Alliance Violin Community Bandung. Purposive sampling was used as sampling technique for this research. The procedure used for this research was referred to Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Results: The result of this research was 30 (16 females and 14 males) violinists with age ranging from 15-30 years old of Alliance Violin Community Bandung were diagnosed with TMD (88.24%). The description of diagnosis of TMD in violinists of Alliance Violin Community Bandung was dominated by disc displacement with reduction with 23 cases (67.65%), arthralgia with 5 cases (14.71%), and myalgia with 4 cases (11.77%). Conclusion: TMD were common in violinists of Alliance Violin Community Bandung, thereby we could conclude that violinists had a high risk of suffering from TMD. The method that was used in this study, DC/TMD, provided more detailed diagnosis so the violinists can raise their awareness of TMD to optimize early medical diagnosis and treatment.

Concordancia entre los criterios diagnósticos RDC/TMD y su actualización DC/TMD, aplicados a la patología inflamatoria de la articulación temporomandibular / Agreement between Diagnostic Criteria RDC/TMD and its update DC/TMD, applied to the inflammatory pathology of the Temporomandibular Joint

RESUMEN: Objetivo: Evaluar el grado de concordancia entre las prevalencias de trastornos articulares inflamatorios (TAI) de las Articulaciones Temporomandibulares (ATM), obtenidas con los Criterios Diagnósticos de Investigación para Trastornos Temporomandibulares (RDC/TMD) y los Criterios Diagnósticos para Trastornos Temporomandibulares (DC/TMD). Materiales y métodos: 59 pacientes adultos chilenos fueron examinados según el Eje I de los RDC/TMD y el Eje I de los DC/TMD para determinar la prevalencia de TAI. Luego se compararon los resultados obtenidos de cada protocolo con el test Kappa de Cohen para evaluar la concordancia entre ambos. Resultados: La prevalencia de TAI para ambos criterios fue de 22%, con una concordancia casi perfecta (kappa=0,91). Al comparar las prevalencias de TAI por articulación, se obtuvo un grado de acuerdo sustancial (kappa=0,77) para la ATM derecha y un grado de acuerdo casi perfecto (kappa=0,94) para la ATM izquierda. Al comparar las prevalencias de TAI según género y edad se obtuvo una concordancia estadísticamente significativa en la mayoría de los casos. Conclusión: Hay concordancia estadísticamente significativa entre los datos obtenidos con los RDC/TMD y los DC/TMD, en el diagnóstico de trastornos articulares inflamatorios.

ABSTRACT: Aim: To assess the agreement between the prevalence of inflammatory joint disorders (IJD) obtained with Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Materials and methods: 59 Chilean adult patients were examined according to Axis I of the RDC/TMD and Axis I of the DC/TMD to determine prevalence of IJD. Then, the results obtained from each protocol were compared with Cohen's Kappa test to assess the agreement between them. Results: The prevalence of IJD for both criteria was 22%, with almost perfect agreement (kappa = 0.91). When comparing the prevalences of IJD per joint, a substantial agreement (kappa = 0.77) was obtained for the right TMJ and an almost perfect agreement (kappa = 0.94) for the left TMJ. When comparing the prevalences of IJD according to gender and age, a statistically significant agreement was obtained in the majority of cases. Conclusion: There is statistically significant agreement between the data obtained with the RDC/TMD and the DC/TMD, in the diagnosis of inflammatory joint disorders.

Prevalence of temporomandibular joint disorders in a mexican elderly group / Prevalencia de trastornos temporomandibulares en un grupo de adultos mayores mexicanos

Abstract: Aim: to determine frequency and distribution of temporomandibulardisorders (TMD) by age and sex in a group of elderly adults in Mexico City. Material and methods: One hundred and fifty-four older adults in Mexico City were examined in a cross-sectional study. Subjects who had big edentulous gaps (absence of two or more teeth) or those who were fully edentulous, as well as those who refused to participate, were excluded from the study. For the epidemiological survey, diagnostic criteria for Temporomandibular Disorders (DC/TMD), after standardization by a dentist (kappa=0.892), were considered. Results. A 33.1 percent had some type of TMD, being more common in people between 60 and 69 years old, variable with which it was related (Likelihood Ratio=21.553, p=0.006, X2 MH=08.389, p=0.021). A 14.3 percent reported some type of facial trauma history, behavior that also was statistically significant (X2 MH=13.566, p= 0.0001). Disorders that occurred most frequently were: disc displacement with reduction (62.8 percent) and disc displacement without reduction (9.8 percent). Conclusions. TMD occurred in one of every three subjects examined, showing a relationship with age and trauma history.

Resumen: Objetivo. determinar la frecuencia y distribución de los trastornos temporomandibulares (TTM) por edad y sexo en un grupo de adultos mayores de la Ciudad de México. Material y métodos. Estudio de corte transversal. Se examinaron 154 adultos mayores de la Ciudad de México. Fueron excluidos del estudio a todos aquellos que presentaron brechas edéntulas amplias (ausencia de dos ó más dientes) o edentulismo total, así como aquellos que no aceptaron participar en el estudio. Para la encuesta epidemiológica se tomaron en cuenta los Criterios Diagnósticos de los Trastornos Temporomandibulares (CD/TTM), previa estandarización de una Cirujana Dentista (kappa=0.892). Resultados. El 33.1 por ciento presentó algún tipo de TTM, siendo más frecuente en personas entre 60 y 69 años variable con la cual estuvo relacionada (Razón de verosimilitud=21,553, p=0,006, X2 MH=08,389, p=0,021). El 14,3 por ciento refirió algún tipo de antecedente traumático facial, comportamiento que también resultó ser estadísticamente significativo (X2 MH=13,566, p=0,0001). Los trastornos que se presentaron con mayor frecuencia fueron: el desplazamiento del disco con reducción (62,8 por ciento) y el desplazamiento del disco sin reducción (9,8 por ciento). Conclusiones. Los TTM se presentaron en uno de cada tres adultos mayores examinados, existiendo una relación con la edad y los antecedentes traumáticos.
