Insights
Bottle feeding and harmful oral habits are linked to malocclusion in preschoolers. This study highlights key risk factors for dental alignment issues in young children, informing early intervention strategies.
Area of Science:
- Pediatric Dentistry
- Public Health
- Oral Health Research
Background:
- Malocclusion, or misaligned teeth, is a common dental issue with potential long-term health implications.
- Early detection and intervention in primary dentition are crucial for managing malocclusion.
- Understanding prevalence and associated factors in preschool populations is vital for targeted public health initiatives.
Purpose of the Study:
- To determine the prevalence of malocclusion in Brazilian preschoolers.
- To identify factors associated with malocclusion, including feeding habits and oral behaviors.
- To investigate specific malocclusion types like open bite and crossbite in relation to risk factors.
Main Methods:
- A cross-sectional study involving 381 children aged 3-5 years in Diamantina, Brazil.
- Clinical oral examinations assessed malocclusion, open bite, crossbite, and crowding.
- Interviews collected data on potential risk factors such as bottle feeding, oral habits, and socioeconomic status.
Main Results:
- The prevalence of malocclusion was 32.5%, with open bite being the most common type.
- Bottle feeding and harmful oral habits significantly increased malocclusion prevalence.
- Boys and children with specific maternal education levels showed higher rates of crossbite.
Conclusions:
- Bottle feeding and harmful oral habits are significant determinants of malocclusion in preschoolers.
- These findings underscore the importance of addressing early feeding and habit interventions to prevent malocclusion.
- Public health strategies should focus on educating parents about risks associated with bottle feeding and oral habits.
Purpose:
To evaluate the prevalence of malocclusion and associated factors in the primary dentition of preschoolers in the city of Diamantina, Brazil.
Methods:
A cross-sectional study was carried out with 381 children aged 3-5 years treated at the 10 basic health care units in the city during immunisation campaigns. The dependent variables (presence of malocclusion, open bite, crossbite and crowding) were evaluated through a clinical oral exam. The independent variables (gender, age, health problems, breastfeeding, bottle feeding, harmful oral habits, mother's schooling, household income and number of children in the home) were collected through interviews. Statistical analysis involved descriptive analysis, Chi square test and Poisson regression.
Results:
The prevalence of malocclusion was 32.5%. Open bite was the most frequent type of malocclusion. Children with a history of bottle feeding (PR 1.74; 95% CI 1.24-2.44) and those with harmful oral habits (PR 1.49; 95% CI 1.23-1.99) had greater prevalence rates of malocclusion. Greater prevalence rates of open bite were also found in children with a history of bottle feeding (PR 5.00; 95% CI 1.99-12.5) and those with harmful oral habits (PR 2.90; 95% CI 1.59-5.29), whereas greater prevalence rates of crossbite were found in boys (PR 1.79; 95% CI 1.10-2.91) and were associated with mother's schooling (PR 1.91; 95% CI 1.20-3.06).
Conclusion:
A history of bottle feeding and the presence of harmful oral habits were identified as determinants for the occurrence of malocclusion in preschoolers.

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.
