Background:
Prevalence data about tooth erosion has attracted increasing attention in the dental community; however, no study has addressed the impact of this condition on child oral health-related quality of life (COHRQoL). This study assessed the impact of tooth erosion on COHRQoL.
Methods:
This study followed a cross-sectional design, with a multistage random sample of 944 11- to 14-year-old children representative of Santa Maria, a southern city in Brazil. They were examined for recording the prevalence and severity of tooth erosion by 2 examiners. Children completed the Brazilian version of Child Perceptions Questionnaire (CPQ(11-14)) and data about socioeconomic variables of the target population were collected by means of a structured questionnaire. The Poisson regression model using robust variance was performed to assess the association between the predictor variables and the outcomes.
Results:
Prevalence of tooth erosion (7.2%) and severity were low. Poisson regression models showed a distinct gradient in mean CPQ(11-14) scores by socioeconomic indicators. Children with tooth erosion with low levels of severity did not report higher means in the total scores or domains of CPQ(11-14).
Conclusion:
The presence of tooth erosion of low severity did not have a significant negative impact on the children's perception of oral health or on their daily performance.

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.
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...
