Insights

Erosive tooth wear (ETW) affects over half of Brazilian preschoolers. Frequent soft drink intake, gastro-oesophageal reflux, and older age are key risk factors for this dental condition.

Area of Science:

  • Pediatric Dentistry
  • Dental Public Health
  • Oral Health Epidemiology

Background:

  • Erosive tooth wear (ETW) is a multifactorial condition affecting tooth structure.
  • Prevalence and risk factors for ETW in preschool populations require further investigation.

Purpose of the Study:

  • To determine the prevalence of ETW in Brazilian preschool children.
  • To identify risk indicators associated with ETW in this age group.

Main Methods:

  • A cross-sectional study involving 967 children aged 3-4 years.
  • Standardized assessment of ETW using a modified O'Brien index.
  • Hierarchical logistic regression analysis to identify risk factors.

Main Results:

  • The prevalence of ETW was 51.6% among the examined children.
  • No significant associations were found with socio-economic, environmental, or nutritional factors.
  • ETW was significantly associated with frequent soft drink consumption (≥2 times/day), gastro-oesophageal reflux, and older age.

Conclusions:

  • A high prevalence of ETW exists in Brazilian preschool children.
  • Frequent soft drink intake, gastro-oesophageal reflux, and age are significant risk indicators for ETW.
  • Targeted preventive strategies are needed for this vulnerable population.

Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
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...
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,...
