Impact of demographic and clinical variables on the oral health-related quality of life among five-year-old children: a population-based study using self-reports.

Untreated dental caries and increased overjet were independently associated with worst OHRQoL in 5-year-old children. As an indication of social deprivation, dark and mixed skin color children compared to light ones presented higher probability for reporting worst OHRQoL independently of the oral clinical conditions.
