OBJECTIVE To investigate the respiratory and postural adaptations associated with mouth and nasal breathing and to evaluate the associations of such adaptations in mouth breathers' self-perceived quality of life. METHOD Cross-sectional study with mouth breathers (initial n=116 and final n=48) and nasal breathers (initial n=131 and final n=24) from elementary school, aged between 7 and 14 year...

BACKGROUND Retention of mouth-to-mouth, mouth-to-mask and mouth-to-face shield ventilation techniques is poorly understood. METHODS A prospective randomised clinical trial was undertaken in January 2004 in 70 candidates randomly assigned to training in mouth-to-mouth, mouth-to-mask or mouth-to-face shield ventilation. Each candidate was trained for 10 min, after which tidal volume, respirator...

OBJECTIVES/HYPOTHESIS Open-mouth breathing during sleep may increase the severity of obstructive sleep apnea (OSA) and complicate nasal continuous positive airway pressure (CPAP) therapy in patients with OSA. The aim of this study was to assess the effect of open-mouth breathing on upper airway anatomy using lateral cephalometry and fiberoptic nasopharyngoscopy. STUDY DESIGN This was a cross-...

OBJECTIVE To determine whether mouth breathing children present the same cephalometric patterns as patients with obstructive sleep apnea syndrome (OSAS). METHOD Cephalometric variables were traced and measured on vertical lateral cephalometric radiographs. The cephalometric measurements of 52 mouth and 90 nose breathing children were compared with apneic patients. The children had not undergo...

Abstract Introduction: Due to the high prevalence of type 2 diabetes and hypothyroidism and the fact that the complication of burning mouth syndrome is seen in both of these diseases, we compared the frequency of burning mouth syndrome in patients with diabetes mellitus type 2 and patients with hypothyroidism referred to Rasht dental school in 1399. Materials and Methods:In this cross-section...

OBJECTIVE To investigate associations between mouth breathing (MBr), nose breathing (NBr) and body posture classification and clinical variables in children and adolescents, by comparing patients with mouth breathing syndrome with a control group of similar age. METHODS This was an observational, analytical, controlled, cross-sectional study conducted at a university hospital. Children aged 5...

STUDY OBJECTIVES The objectives of this study were (1) to evaluate the way in which nasal continuous positive airway pressure (CPAP) therapy influences the relative humidity (rH) of inspired air; and (2) to assess the impact on rH of the addition of an integrated heated humidifier or a full face mask to the CPAP circuitry. DESIGN The studies were performed in 25 patients with obstructive slee...
