Diagnosis of juvenile idiopathic arthritis with asymptomatic involvement of the temporomandibular joint: A case report.

Juvenile idiopathic arthritis (JIA) is a broad term that describes a group of heterogeneous rheumatologic diseases, mainly characterized by inflammation in the joints of children and young people up to 16 years of age. Its etiology is still not well understood and the diagnosis, essentially clinical, begins with the exclusion of other joint diseases. When the disease affects the temporomandibular joint, diagnosis is a challenge, as many patients are asymptomatic.

Tomographic Evaluation of the Lower Incisor's Bone Limits in Mandibular Symphysis of Orthodontically Untreated Adults.

The amount of available bone in the lower incisor region is critical for periodontal preservation when planning large anteroposterior dental movements. The aims of this study were to evaluate bone limits of the lower incisors in the mandibular symphysis and to verify whether they are influenced by facial growth patterns, lower incisor inclinations, skeletal anteroposterior relationships, or patient age. Tomographic images of 40 orthodontically untreated patients were evaluated and measurements of width and height of the mandibular symphysis, thickness on the lingual and labial sides of the alveolar bone, and thickness of the entire alveolar bone were performed in sagittal view.
