Morphological evaluation of temporo-mandibular joint in indian population

The temporomandibular joint (TMJ) is one of the most complex joints in the body and its harmonious functioning is very important to maintain a normal masticatory system. The morphologic alterations and the asymmetrical position of the TMJ structures may lead the various clinicalsigns & symptoms. Morphology of the temporomandibular joint may be influenced by gender of patients, environmental factor and also food habits at various places. Objective: To evaluate the morphology of the temporomandibular joint using computed tomography, in order to determine the condyle shape, joint space and glenoid fossa roof thickness. Material and Methods: One hundred and six healthy patients (212 TMJs) who visited a private hospital (or the University's Hospital) for CT brain scan were included to this crosssectional study sample.The patients were aged between 20­50 years with an average age of 35.46 years. All the images were taken by positioning patients in supine position with 120kvp , 50ma,2.33minute exposure with 0.7mm thick slicesby computed topography machine in all three projection that is Axial, Coronal and Saggital view. Results: For all variables, the mean and standard deviation were calculated, based on gender, and TMJ sides. The Paired t-test was used and P Objetivo: A articulacao temporomandibular (ATM) e uma das articulacoes mais complexas do corpo e seu funcionamento harmonioso e muito importante para manter um sistema mastigatorio. As alteracoes morfologicas e a posicao assimetrica das estruturas da ATM podem levar os varios sinais e sintomas clinicos. A morfologia da articulacao temporomandibular pode ser influenciada pelo genero dos pacientes, fatores ambientais e tambem habitos alimentares diversos. Objetivo: Avaliar a morfologia da articulacao temporomandibular usando tomografia computadorizada, a fim de determinar a forma do condilo, o espaco articular, e a espessura do teto da fossa glenoide. Material e Metodos: Cento e seis pacientes saudaveis (212 ATMs) que foram a um hospital privado (ou Hospital da Universidade) para tomografia computadorizada de cerebro foram incluidos na amostra deste estudo transversal. Os pacientes tinham entre 20 e 50 anos com uma idade media de 35,46 anos. Todas as imagens foram tiradas com os pacientes posicionados em decubito dorsal com 120kvp, 50mA, 2,33minutos de exposicao com espessura de 0.7mm nas tres projecoes: Axial, Coronal e Saggital. Resultados: Para todas as variaveis, a media e desvio padrao foram calculados, com base no sexo e nos lados da ATM. O teste t pareado foi usado e P
