Insights

Sleep-related breathing disorders (SRBD) affect 22.8% of children undergoing orthodontic treatment. SRBD is linked to smaller maxillary width and less overbite, highlighting the need for early identification in paediatric patients.

Area of Science:

  • Paediatric Sleep Medicine
  • Orthodontics
  • Craniofacial Health

Background:

  • Sleep-related breathing disorders (SRBD) are common in children, with craniofacial abnormalities being a significant risk factor.
  • Identifying SRBD in paediatric patients undergoing orthodontic treatment is crucial due to its high prevalence.

Purpose of the Study:

  • To determine the prevalence of SRBD in children seeking interceptive orthodontic treatment.
  • To investigate the association between SRBD and craniofacial and occlusal variables in this population.

Main Methods:

  • A prospective study involving 249 healthy children.
  • Utilized the Paediatric Sleep Questionnaire and Sleep Disturbance Scale for Children.
  • Included orthodontic diagnosis, dental cast analysis, and cephalometric analysis.

Main Results:

  • SRBD was present in 22.8% of the study sample.
  • Patients with SRBD showed significantly smaller maxillary width and less overbite.
  • A history of adenotonsillectomy was associated with a higher prevalence of SRBD.

Conclusions:

  • SRBD is highly prevalent in paediatric orthodontic patients, necessitating screening.
  • Specific craniofacial characteristics, including reduced maxillary width and overbite, are associated with SRBD.
  • Orthodontic treatment demonstrated significant improvements in reported sleep disturbances.

Sleep Apnea01:21

Sleep Apnea

Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Physical Assessment of the Respiratory Tract II: Inspection

Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Assessment of Airway, Skin Color, and Use of Accessory Muscles

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Breathing01:05

Breathing

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
