Periodontal health and compliance: A comparison between Essix and Hawley retainers.

Introduction: Many studies on removable retainers have focused on retention efficacy and characteristics. However, studies on plaque accumulation, periodontal health, breakages, and patient compliance are still lacking. Thus, in this study, we aimed at evaluating these parameters in 2 groups of young patients wearing Essix or Hawley retainers for a 6-month period.

Rapid Maxillary Expansion in Obstructive Sleep Apnea in Young Patients: Cardio-Respiratory Monitoring.

Objective(s): Obstructive sleep apnea syndrome (OSAS) is a respiratory disorder which affects from 1 to 3 % of people during development. OSAS treatment may be pharmacological, surgical or based on application of intraoral devices to increase nasal respiratory spaces. The purpose of this study was to determine the efficacy of the Rapid Maxillary Expander in OSAS young patients by measuring cardio-respiratory monitoring parameters (AHI, the average value of complete and incomplete obstructed respiration per hour of sleep, and SAO, the percentage of oxygen saturation).

Rapid palatal expansion and pharyngeal space. Cephalometric evaluation.

Objectives: the aim of this study was to evaluate cephalometrically the upper respiratory airway dimensions before and after rapid maxillary expansion.

Materials And Methods: rapid palatal expansion was performed on 24 5-9 year old children with adenotonsillar hypertrophy determined radiographically by means of lateral cephalographs. Also, the subjects were questioned concerning their ability to breath through their noses.
