Cephalometric Measurements of Upper Airway at Upright and Supine Posture in Adult OSAS Patients.

This article aims to investigate whether posture (upright vs. supine) affects airway-related cephalometric measurements in adult Chinese patients with obstructive sleep apnea syndrome (OSAS).Twenty-seven adult Chinese male patients with OSAS (mean age, 50.

Functional therapy and adenotonsillectomy clinical trial for class II malocclusion (FACT-II): protocol for a randomised controlled trial.

Introduction: Class II malocclusion with mandibular retrognathia is a common complication of paediatric obstructive sleep apnoea (OSA), often accompanied by transverse maxillary deficiency. In early orthodontic treatment, a twin block (TB) is a regular functional appliance for correcting this malocclusion. For paediatric OSA, the most common risk factor is adenotonsillar hypertrophy (AHT).

The knowledge, experience, and attitude on artificial intelligence-assisted cephalometric analysis: Survey of orthodontists and orthodontic students.

Introduction: Artificial intelligence (AI) developed rapidly in orthodontics, and AI-based cephalometric applications have been adopted. This study aimed to assess AI-assisted cephalometric technologies related knowledge, experience, and attitude among orthodontists and orthodontic students; describe their subject view of the applications and related technologies in orthodontics; and identify associated factors.

Methods: An online cross-sectional survey based on a professional tool (www.

Obstructive sleep apnea-related knowledge, attitude, experience, and behaviors among orthodontic professionals: a survey.

Purpose: To assess obstructive sleep apnea (OSA)-related experience, knowledge, attitude, and behaviors among orthodontic professionals in China and identify factors associated with their knowledge levels, attitude toward referring, and self-confidence in the management of patients with OSA.

Methods: An online cross-sectional survey was conducted using a 31-item questionnaire developed with a professional online survey tool ( www.wjx.

The impact of mouth breathing on dentofacial development: A concise review.

Mouth breathing is one of the most common deleterious oral habits in children. It often results from upper airway obstruction, making the air enter completely or partially through oral cavity. In addition to nasal obstruction caused by various kinds of nasal diseases, the pathological hypertrophy of adenoids and/or tonsils is often the main etiologic factor of mouth breathing in children.

[Preliminary study on nasal spray of interferon alpha-2b used for prevention of rubella and measles virus infections].

Objective: To evaluate the efficacy of the interferon alpha-2b nasal spray in prevention of rubella and measles virus infections.

Methods: The properly selected volunteer groups have been divided into interferon alpha-2b experimental and control group. The experimental group received interferon alpha-2b treatment by nasal spray for 2 days before the immunization, then both groups were challenged with rubella and measles attenuated live vaccine respectively through nasal spray.
