Insights

Dental injuries are common in Belo Horizonte preschoolers, affecting 39.1%. Boys and children with inadequate lip coverage face higher risks, highlighting a significant public health issue.

Area of Science:

  • Pediatric Dentistry
  • Public Health
  • Epidemiology

Background:

  • Traumatic dental injuries are a significant concern in pediatric populations.
  • Understanding prevalence and risk factors is crucial for prevention strategies.

Purpose of the Study:

  • To determine the prevalence of traumatic dental injuries in preschool children in Belo Horizonte, Brazil.
  • To identify factors influencing the occurrence of these injuries.

Main Methods:

  • A cross-sectional survey involving clinical examinations and parental questionnaires.
  • 419 children aged 0-5 years from randomly selected preschools in Belo Horizonte were assessed.

Main Results:

  • The prevalence of traumatic dental injuries was 39.1%, with enamel fractures being the most frequent type (49.7%).
  • Boys (OR=1.62), children with inadequate lip coverage (OR=3.75), and those in state preschools (OR=1.97) showed significantly higher odds of injury.

Conclusions:

  • Traumatic dental injuries represent a high prevalence and a public health problem among preschool children in Belo Horizonte.
  • Risk factors such as gender, lip coverage, and type of preschool attendance require targeted intervention.

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health condition at a...
Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events, are a...
