Does the Rigid External Distraction Device Alter Maxillary Pitch in Cleft Maxillary Distraction?

The rigid external distraction (RED) device is reported to have the ability to three-dimensionally reposition the maxilla. The purpose of this study is to assess the ability of RED to intentionally alter the maxillary pitch. Retrospective cohort study.

Current Concepts in Prophylactic Antibiotics in Oral and Maxillofacial Surgery.

Antibiotic prophylaxis is the use of antibiotics in the perioperative period to prevent surgical site infections from local flora. Specific guidelines and criteria exist to prevent these infections while also practicing antimicrobial stewardship. Most dentoalveolar procedures do not require antibiotic prophylaxis.

Comparison of the condyle-fossa relationship and resorption between patients with and without Juvenile Idiopathic Arthritis (JIA).

Purpose: The purpose of this study was 1) to compare condyle - fossa relationships in the temporomandibular joint (TMJ), and 2) to score condylar resorption by using a TMJ indexing system in patients with JIA and without JIA.

Methods: The present retrospective cross-sectional study included cone-beam computed tomography (CBCT) images obtained from the sagittal, coronal, and axial slices. In the multidisciplinary Pediatric Rheumatology Outpatient Clinic at The University of Alabama at Birmingham (UAB) children with JIA are also examined by a group of orthodontists working in the same institute from October 2018 to July 2019.

Use of a 'low and short' medial cut limits sagittal ramus osteotomy interferences.

The traditional 'high and short' medial cut of the sagittal ramus osteotomy (Hunsuck modification) is a frequent cause of lingual plate interferences in patients undergoing mandibular yaw or cant corrections. We describe how the modified 'low and short' medial cut of the sagittal ramus osteotomy reduces lingual plate interferences with improved passive alignment of the osteotomy segments.

Management of juvenile idiopathic arthritis: Preliminary qualitative findings from the National Dental Practice-Based Research Network.

Introduction: Juvenile idiopathic arthritis (JIA) is the most common chronic arthritis in childhood and represents a series of chronic inflammatory arthritides that develop before 16 years of age.

Methods: In 2020, investigators with an interest in the management of JIA engaged the National Dental Practice-Based Research Network by conducting a preliminary qualitative questionnaire ("Quick Poll") that comprised 6 questions about JIA management.

Results: A total of 604 persons responded.

Is a Final Splint Necessary in Bimaxillary Orthognathic Surgery?

For bimaxillary orthognathic surgery, a splint is commonly used to achieve the final occlusion and is then maintained through initial skeletal healing. The purpose of this study is to document how often a final splint is used to achieve the planned intraoperative occlusion, and how often is the final splint retained after surgery to maintain the occlusion during the initial skeletal healing phase.The investigators developed a retrospective case series.

Endotracheal Tube Fixation via a Modified Ivy Loop in a Pediatric Patient With Facial Burns: A Technical Note.

Securing an endotracheal tube in a child with a facial burn is crucial but often challenging. The traditional method of using a facial apparatus or tape tied around the lower face is not suitable in the setting of open facial wounds as it limits wound care and, if necessary, skin grafting. We describe a straightforward, quick method to secure the endotracheal tube by means of a modified ivy loop in a pediatric patient.
