Temporomandibular joint disc position and shape in patients submitted to two protocols of rapid maxillary expansion and face mask therapy: A randomized clinical trial.

Objective: The objective of this prospective study was to assess possible changes in the position and shape of the temporomandibular joint (TMJ) articular disc in patients treated with two protocols of rapid maxillary expansion (RME) and face mask (FM) therapy.

Methods: A sample of 88 patients with Class III or Class III subdivision malocclusions, aged between 6 and 13 years, were consecutively selected and divided into three groups (G): G1-34 patients were treated with RME, followed by FM therapy; G2-34 patients were treated using RME according to modified alternate rapid maxillary expansion and constriction (ALT-RAMEC) protocol, followed by FM therapy. These treated groups were randomly (1:1 allocation ratio) distributed according to the two treatment protocols.

Associations between skeletal discrepancies, breathing pattern, and upper airway obstruction in Class III malocclusions.

Objective: To verify the associations between sagittal and vertical skeletal discrepancies, changes in upper airways, and breathing pattern in children and adolescents with Angle Class III and Class III subdivision malocclusions.

Methods: Eighty-five children and adolescents with a mean age of 9.5 ± 1.

Temporomandibular joint articular disc position and shape in skeletal Class III.

Objective: To compare the position and shape of the temporomandibular joint (TMJ) articular disc among the sagittal and vertical skeletal patterns in Angle Class III, Class III subdivision malocclusion and normal occlusion. The null hypothesis was that there was no difference in disc position and shape in different (1) malocclusions and (2) skeletal patterns.

Methods: This cross-sectional observational study evaluated 105 patients divided into 3 groups: Class III (33, 9.

Applicability of Cone Beam Computed Tomography to the Assessment of the Vocal Tract before and after Vocal Exercises in Normal Subjects.

Background/aims: Cone beam computed tomography (CBCT), which represents an alternative to traditional computed tomography and magnetic resonance imaging, may be a useful instrument to study vocal tract physiology related to vocal exercises. This study aims to evaluate the applicability of CBCT to the assessment of variations in the vocal tract of healthy individuals before and after vocal exercises.

Methods: Voice recordings and CBCT images before and after vocal exercises performed by 3 speech-language pathologists without vocal complaints were collected and compared.

Dentofacial characteristics of oral breathers in different ages: a retrospective case-control study.

Background: This study aimed to investigate the dental and skeletal variables associated with disturbances of craniofacial development in oral-breathing (OB) individuals and the probability that these variables are related to this condition.

Methods: This is an observational retrospective case-control study of 1596 patients divided into three groups of age n1 5-12, n2 13-18, and n3 19-57 years. Radiographic, clinical, and models data were analyzed.

Mycetoma caused by Fusarium solani with osteolytic lesions on the hand: case report.

Eumycetoma is a mycotic disease caused by saprophytic soil fungi that are usually inoculated through minor injuries. A case of mycetoma in a Brazilian farmer aged 71 years is reported. This patient presented erythema and edema on the dorsal surface of the left hand with multiple crusted and cicatricial lesions.
