Insights

Children with skeletal class II malocclusion often experience sleep problems, including snoring and decreased airway space. These sleep issues are significantly associated with specific craniofacial characteristics.

Area of Science:

  • Pediatric Dentistry
  • Orthodontics
  • Sleep Medicine

Background:

  • Sleep problems in children can lead to behavioral issues, poor academic performance, and failure to thrive.
  • Evaluating the prevalence and associations of sleep problems in children with skeletal class II malocclusion with mandibular retrognathism is crucial.

Purpose of the Study:

  • To determine the associations between sleep practices/problems and craniofacial characteristics in children with skeletal class II malocclusion and mandibular deficiency.

Main Methods:

  • A cross-sectional study involved 50 children (aged 8-14) with skeletal class II malocclusion and mandibular retrognathism.
  • Sleep practices and problems were assessed using a validated questionnaire.
  • Clinical examinations and lateral cephalograms evaluated craniofacial variables, including pharyngeal airway space.

Main Results:

  • All participants reported at least one sleep problem, with 76% experiencing snoring.
  • Reduced upper airway was observed in 42%, and reduced lower airway in 80% of children.
  • Significant associations were found between mandibular plane angle (SN-MP) and noisy breathing/snoring, and between airway dimensions and sleep positions.

Conclusions:

  • Every child in the study exhibited at least one sleep problem.
  • A strong association exists between specific sleep practices/problems and measurable cephalometric variables in this population.

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.

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...

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.

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...
