Insights

Children with sleep bruxism are more likely to bite objects and clench teeth during the day. These daytime parafunctions, alongside primary canine wear, are key risk factors for sleep bruxism in children.

Area of Science:

  • Pediatric Dentistry
  • Sleep Medicine
  • Public Health

Background:

  • Sleep bruxism, characterized by teeth grinding during sleep, affects children.
  • Identifying associated clinical signs, symptoms, and parafunctions is crucial for understanding its etiology.

Purpose of the Study:

  • To investigate the association between clinical signs, parafunctions, and factors related to sleep bruxism in children.
  • To identify risk factors for sleep bruxism in a pediatric population.

Main Methods:

  • A population-based case-control study involving 120 children with sleep bruxism and 240 controls (age 8).
  • Random sampling from schools in Belo Horizonte, Brazil, matched for gender and social class using the Social Vulnerability Index.
  • Diagnosis of sleep bruxism followed American Association of Sleep Medicine criteria; statistical analysis included logistic regression.

Main Results:

  • Primary canine wear (OR=2.3), biting objects (OR=2.0), and wake-time bruxism (OR=2.3) were significant risk factors for sleep bruxism.
  • Children exhibiting object biting and wake-time bruxism were more susceptible to developing sleep bruxism.

Conclusions:

  • Object biting and wake-time bruxism are significant parafunctional risk factors for sleep bruxism in children.
  • Early identification of these parafunctions may aid in managing or preventing pediatric sleep bruxism.

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...
Sleepwalking and Sleep Talking01:17

Sleepwalking and Sleep Talking

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...
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.
Nightmares often...
Narcolepsy01:07

Narcolepsy

Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.
Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...
