Insights

Sleep bruxism affects nearly half of preschool children, linked to oral habits and behavioral issues. It significantly impacts children's oral health-related quality of life.

Area of Science:

  • Pediatric Dentistry
  • Sleep Medicine
  • Public Health

Background:

  • Sleep bruxism is a common condition in children.
  • Understanding its prevalence and associated factors is crucial for early intervention.
  • The impact on quality of life warrants further investigation.

Purpose of the Study:

  • To determine the prevalence of sleep bruxism in preschool children.
  • To identify factors associated with sleep bruxism.
  • To evaluate the impact of sleep bruxism on oral health-related quality of life (OHRQoL).

Main Methods:

  • A cross-sectional study involving 475 preschool children (4-5 years old) in Bauru, Brazil.
  • Data collected via parental questionnaires on bruxism, related factors, and the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS).
  • Clinical intraoral examinations and statistical analysis, including Mann-Whitney, Kruskal-Wallis, and Spearman correlation tests.

Main Results:

  • The prevalence of sleep bruxism was 47.4%.
  • Associated factors included specific canine classifications (Class I), marked overjet, oral habits (nail biting, lip biting, gum chewing, mouth breathing), agitated sleep, headaches, and certain behavioral traits (aggression, anxiety, shyness).
  • Sleep bruxism was identified as the primary factor negatively affecting children's OHRQoL.

Conclusions:

  • Sleep bruxism is highly prevalent in this preschool sample.
  • Oral and general health factors are significantly associated with sleep bruxism.
  • Sleep bruxism substantially compromises the oral health-related quality of life for children and their families.

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.

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...

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.

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.

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...

Psychosexual Stages of Personality: Oral01:16

Psychosexual Stages of Personality: Oral

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.
Weaning, typically occurring...
