background and aims. trauma is one of the major factors associated with temporomandibular joint disorders (tmd). these disorders result from macro-trauma or micro-trauma. macro-trauma might be iatrogenic; for example, from intubation procedures, third molar extraction procedures, and lengthy dental appointments. the aim of this study was to evaluate the effect of lengthy root canal therapy (mor...

OBJECTIVE This study aimed to evaluate the possibility of any correlation between disc displacement and parameters used for evaluation of skull positioning in relation to the cervical spine: craniocervical angle, suboccipital space between C0-C1, cervical curvature and position of the hyoid bone in individuals with and without symptoms of temporomandibular dysfunction. MATERIAL AND METHODS Th...

INTRODUCTION Temporomandibular disorders encompass a set of clinical conditions that affect the temporomandibular joint, the masticatory muscles and the associated tissues. Many therapeutic alternatives can be considered, being divided into non-invasive, minimally invasive and invasive interventions. This work aims to report a case of inflammatory joint pain and dysfunction treated with bilater...

OBJECTIVES To investigate the reliability of regional three-dimensional registration and superimposition methods for assessment of temporomandibular joint condylar morphology across subjects and longitudinally. METHODS The sample consisted of cone beam CT scans of 36 patients. The across-subject comparisons included 12 controls, mean age 41.3 ± 12.0 years, and 12 patients with temporomandibul...

OBJECTIVES Dislocation of the temporomandibular joint may occur for various reasons. Although different invasive methods have been advocated for its treatment, this study highlights the value of non-invasive treatment options even in chronic cases in a resource-poor environment. MATERIALS AND METHODS A seven-year retrospective analysis of all patients managed for temporomandibular joint dislo...

OBJECTIVE In this study, we aimed to examine the relationship between chin deviation and the positional and morphological features of the mandible and to determine the factors that contributed to chin deviation in individuals with a unilateral cleft lip and palate (UCLP). METHODS Cone-beam computed tomography (CBCT) images of 28 adults with UCLP were analyzed in this study. Segmented three-di...

INTRODUCTION To establish the skeletal pattern in subjects with malocclusions and temporomandibular disorders (TMD); to assess the relationship between craniofacial skeletal structures and TMD in subjects with malocclusions. MATERIAL AND METHODS Sixty-four subjects with malocclusions, over 18 years of age, were included in the study. Temporomandibular disorders were clinically assessed accord...

The smallest detectable difference is the smallest statistically significant change in measurement results. In the field of temporomandibular disorders, the smallest detectable difference is not a commonly used concept. Most outcome studies are based on comparisons of group means, although this does not provide information about individual changes or about the clinical relevance thereof. The sm...

Arthritis is a common disease affecting the temporomandibular joint. The inflammation causes local pain and decreased function of the masticatory system. Temporomandibular joint arthritis can result from mechanical overloading, general autoimmune disease or individual susceptibility. The aim of this study was to investigate objective and subjective treatment results after intra-articular inject...
