Tooth Anatomy01:21

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.
Teeth01:15

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...
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Oral Cavity01:11

Oral Cavity

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Summary

Children who miss dental appointments often have higher caries risk. These children require targeted dental care and closer monitoring to improve oral health outcomes.

Area of Science:

  • Pediatric Dentistry
  • Dental Public Health
  • Caries Research

Background:

  • Non-compliance with dental appointments is a significant issue in pediatric dental care.
  • Understanding factors associated with missed appointments is crucial for effective dental service delivery.

Purpose of the Study:

  • To identify factors linked to children's non-compliance with regular dental appointments.
  • To compare oral health, behaviors, and service use between children with and without broken appointments.

Main Methods:

  • A study involving 576 children recalled for routine dental examinations in public services.
  • Data collected included appointment history, demographics, oral health status, and clinical findings.
  • Multiple logistic regression analysis was used to analyze the data.

Main Results:

  • 15% of children had broken at least one appointment in the preceding 2 years.
  • No significant demographic or behavioral differences were found between groups.
  • Children with broken appointments exhibited more enamel disturbances, higher caries experience, and increased caries activity.

Conclusions:

  • Children with a history of broken dental appointments are identified as high-caries risk patients.
  • These children necessitate specialized attention and management within dental services.
  • Shorter recall intervals were assigned to children with a history of missed appointments.
