Purpose: The aim of this study was to estimate prevalence of temporomandibular Joint disorders (TMDs), among dental university student in Yemen. Material and methods:A prospective cross-sectional study was conducted in the Department of Oral Medicine and Oral Diagnosis, Faculty of Dentistry, Thamar University, Yemen. Study sample consisted of 207 university students (114 males and 93 females). Predictor's variables were age, gender and marital status. The outcomes variables were the signs and symptoms of TMDs using the Helkimo clinical dysfunction (Di) and anamnestic (Ai) indices. Results:The results revealed that prevalence of TMDs among Yemeni dental students was 41.07 % (mild: 14.01%, sever: 27.05%). In the clinical examination, 49.76 % (mild: 20.77%, moderate; 12.08% and sever; 16.91%) showed some degree of dysfunction. Females showed a signifi cant higher prevalence of TMDs than males. There was signifi cant association between the dysfunction of TMD and gender (P > 0.005). Conclusion:The result of this study showed that prevalence of TMDs among Yemeni dental students was higher than some studies have reported in the literature. Also, the results revealed that majority of studied sample were not aware of the presence of their TMD

“…This study used Kjellberg’s technique because it is easier to identify the condylar height using this technique than Habet’s method. Habet’s method is more complicated when making reference points of the most lateral point of the condyle due to variation in the condylar anatomy 16, 17, 31 .…”

TMD symptoms and vertical mandibular symmetry in young adult orthodontic patients in North Sumatra, Indonesia: a cross-sectional study

et al. 2018

Background: Temporomandibular joint disorder (TMD) includes symptoms of pain and dysfunction in the muscles of mastication and the temporomandibular joint. Differences in vertical condylar height, observed in the assessment of mandibular asymmetry, is a structural alteration that represents a risk factor for TMD. The study aimed to evaluate the association between TMD symptoms and vertical mandibular symmetry in young adult orthodontic patients in North Sumatra, Indonesia. Methods: The cross-sectional study included 18-25-year-old (mean ± SD, 21.9 ± 2.0 years) old orthodontic patients admitted to the Dental Hospital of Universitas Sumatera Utara, Medan, between June 2016 and March 2017. Vertical mandibular asymmetry was assessed from all 106 subjects using Kjellberg’s technique from pre-treatment panoramic radiographs. The TMD symptoms were assessed by structural interviews using modified questionnaires based on Temporomandibular Disorder Diagnostic Index and Fonseca’s Anamnestic Index. Results: Of the 106 subjects, 26 (24.5% of the total) with vertical mandibular symmetry and 39 (36.8%) with vertical mandibular asymmetry were positive for TMD symptoms. By contrast, 17 patients (16.0% of the total) with vertical condylar symmetry and 24 patients (22.6%) with vertical mandibular asymmetry were regarded negative for TMD symptoms. There was no significant difference (p=0.520) in TMD symptoms based on vertical mandibular symmetry. Conclusion: The results from this studied Sumatran population indicate that there are common TMD symptoms in young adult orthodontic patients, but there is no significant association between vertical mandibular asymmetry and TMD symptoms. Further study on the development of TMD, mandibular asymmetry and treatment planning for growing patients is suggested, using longitudinal and transitional approaches.

RESUMEN:La asimetría condilar (AC) es una alteración morfológica estructural considerada un importante factor de riesgo para los trastornos de la articulación temporomandibular. Diversas técnicas evalúan la AC, principalmente basadas en mediciones sobre radiografías panorámicas, dado su amplio uso. Sin embargo, los métodos sobre radiografías no son muy sensibles por la magnificación, distorsión, superposición de estructuras y posicionamiento mandibular. El objetivo de este estudio fue determinar los valores reales de los índices de asimetría condilar para una muestra normal con medición directa sobre mandíbulas humanas. Se utilizaron 30 mandíbulas humanas adultas secas pertenecientes a población chilena, y la asimetría condilar fue evaluada las técnicas de Habets y de Kjellberg, y se realizaron los análisis descriptivos de los valores promedios, desviación estándar, mínimo y máximo y los índices de asimetría/simetría de cada método. Según el índice de asimetría condilar de Habets 7 casos (un 23,3%) mostraron valores superiores a un índice de 3% de asimetría, con un rango entre 3,64 y 27,26%. Los parámetros morfológicos del lado derecho e izquierdo no mostraron diferencias significativas (p < 0,05). Según el índice de simetría de Kjellberg, 19 casos (63,3%) mostraron valores inferiores al 93% y fueron clasificados como asimétricos. Los parámetros morfológicos del lado derecho e izquierdo tampoco mostraron diferencias significativas. Al comparar las asimetrías reportadas con ambos métodos, sólo en 4 casos hubo una coincidencia de diagnóstico. Al eliminar factores de distorsión y angulación en las mediciones realizadas, se confirma la existencia de asimetría vertical entre los cóndilos mandibulares del lado derecho e izquierdo, y por otra parte, es evidente que hay diferencias en los valores de asimetría debido a los diferentes métodos utilizados. Sin embargo, todavía no está claro que la asimetría condilar puede considerarse fisiológica.PALABRAS CLAVE: Cóndilo mandibular; Asimetría condilar; Mandíbula humana; Articulación temporomandibular. INTRODUCCIÓNLa asimetría condilar (AC) es una alteración morfológica estructural, considerada un importante factor de riesgo para los trastornos de la articulación temporomandibular (TTM) (Silva & Fuentes, 2004). La AC se define como la comparación de la altura vertical condilar entre el proceso condilar del lado derecho e izquierdo (Saglam & Sanli, 2004), pero también puede involucrar al cuello del cóndilo y la rama mandibular.La determinación de la AC ha sido ampliamente utilizada como complemento de las pruebas clínicas de diagnóstico en los pacientes con TTM (Miller & Bodner, 1997;Miller et al, 1998;Saglam, 2003;Sezgin et al., 2007). Con este fin, se han desarrollado diversas técnicas para evaluar la AC, principalmente basadas en mediciones sobre radiografías panorámicas, dada la relativa sencillez de la técnica, amplia utilización de esta radiografía y la baja dosis de radiación a que está expuesto el paciente (Kjellberg et al., 1994). describen una técnica que consiste e...
