Insights
Dental erosive wear is common in five-year-olds, affecting about 80%. Teeth grinding and male sex were linked to more severe cases of this dental condition.
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Epidemiology
Background:
- Dental erosive wear is a growing concern in pediatric populations.
- Understanding its prevalence and associated factors is crucial for early intervention.
Purpose of the Study:
- To determine the prevalence of dental erosive wear in five-year-old children in Bergen, Norway.
- To identify background factors associated with severe dental erosive wear.
Main Methods:
- Dental examinations were conducted on 387 children across five dental clinics.
- Parental questionnaires gathered data on hygiene, diet, and background factors.
- Statistical analyses included Chi-squared tests and logistic regression to assess associations.
Main Results:
- Approximately 80% of children exhibited signs of dental erosive wear.
- Maxillary anterior teeth were affected in 13.9% of cases, while molar cupping was observed in 79.3%.
- Bruxism (teeth grinding) and male sex were significantly associated with the most severe erosive wear outcomes.
Conclusions:
- Dental erosive wear is highly prevalent among young children in Bergen.
- Bruxism and being male are risk factors for more severe dental erosive wear.
Objective:
To estimate the prevalence of dental erosive wear among five-year-olds in Bergen, Norway, and to investigate associations between background factors and the condition.
Methods:
A total of 387 children received a dental examination in five Public Dental Service clinics in Bergen, Norway. The parents responded to items about the children's dental hygiene and drinking habits, type of beverage container, diet, and other habits, and about their own age, educational level and country of origin. We explored background variables for possible associations with the outcome status as worst affected by erosive wear (19.4%, n = 75). Chi-squared statistics and logistic regression (Odds Ratios (OR): 95% Confidence Intervals (CI), served as statistical tools).
Results:
Approximately 80% showed erosive wear (by SEPRS and by adopted diagnostic instrument (78.5% vs 79.8%)). The condition affected maxillary anterior teeth in 13.9% (n = 54), and cuppings in molars in 79.3% (n = 307) of cases. Grinding teeth during the day and/or night (OR: 1.87, CI: 1.07-3.25) and male sex (OR: 1.76, CI: 1.05-2.96) significantly related to outcome status as worst affected by erosive wear, respectively.
Conclusion:
Dental erosive wear was widespread. Grinding teeth and male sex associated with outcome status as worst affected by erosive wear.

Teeth
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 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.
Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
