Malocclusion and socioeconomic indicators in primary dentition
Brazilian Oral Research
|July 9, 2014
Summary
Malocclusion affects over 60% of preschoolers, with increased overjet being most common. This study found no link between malocclusion and socioeconomic factors in Brazilian children.
Area of Science:
- Pediatric Dentistry
- Public Health
- Epidemiology
Background:
- Malocclusion is a common dental issue in children.
- Understanding its prevalence and risk factors is crucial for early intervention.
- Socioeconomic factors may influence malocclusion development.
Purpose of the Study:
- To determine the prevalence of malocclusion in Brazilian preschoolers.
- To investigate associations between malocclusion and socioeconomic indicators.
- To identify specific malocclusion types in the study population.
Main Methods:
- Cross-sectional study of 732 children aged 3-5 years in Campina Grande, Brazil.
- Calibrated dentists diagnosed malocclusion using established criteria.
- Sociodemographic data collected via parental questionnaires; analyzed with Poisson regression.
Main Results:
- High malocclusion prevalence (62.4%) observed.
- Increased overjet (42.6%), anterior open bite (21%), and deep overbite (19.3%) were most frequent.
- Malocclusion prevalence was higher in younger children (3-year-olds).
Conclusions:
- Malocclusion is highly prevalent in Brazilian preschoolers.
- No significant association found between malocclusion and maternal education or household income.
- Socioeconomic status did not appear to be a determining factor for malocclusion in this cohort.

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...

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...

01:26Assessment of the Mouth
1.6K
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.

01:28Development of the Oral Microbiota
62
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,...
