Summary
Sleep Disordered Breathing (SDB) is linked to specific dental issues in children. Crossbite and open bite malocclusions were found to be associated with SDB, suggesting they may predict its occurrence.
Area of Science:
- Pediatric dentistry
- Sleep medicine
- Orthodontics
Background:
- Sleep Disordered Breathing (SDB) is common and linked to orofacial and dentofacial features.
- Understanding these associations is crucial for early diagnosis and intervention in children.
Purpose of the Study:
- To investigate the relationship between various dental malocclusions and SDB in children aged 7-9 years.
- Specifically examining molar relationship, crossbite, open bite, overjet, overbite, and crowding.
Main Methods:
- A two-phase study involving 1216 children aged 7-9 years.
- Phase 1: Parental SDSC questionnaires and dental examinations. Phase 2: Polysomnography (PSG) for 60 randomly selected children.
- Occlusion evaluated using sagittal, vertical, and transverse analyses.
Main Results:
- Out of 1216 children, 19.9% had normal occlusion.
- Of 60 children undergoing PSG, 80% (40 children) had SDB.
- Crossbite and open bite were significantly associated with SDB (p=0.04).
Conclusions:
- Crossbite and open bite malocclusions are associated with SDB in children.
- These malocclusions may serve as predictors for SDB.
- Further research with larger cohorts and clinical trials on orthodontic/orthopedic interventions is recommended.

895
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.

01:30Alterations in Respiration II
2.5K
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

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.

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.

Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

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.
