Signs of attention deficit/hyperactivity disorder as a risk factor for traumatic dental injury among schoolchildren: a case-control study.

Background: The determination of risk factors for traumatic dental injury (TDI) is important to the implementation of preventive measures.

Aim: The aim of this study was to evaluate the association between signs of attention deficit/hyperactivity disorder (ADHD) and TDI.

Material And Methods: A case-control (1 : 1) study involved a population-based sample of 230 schoolchildren aged seven to 12 years.

Impact of untreated dental caries and its clinical consequences on the oral health-related quality of life of schoolchildren aged 8-10 years.

Objective: This study aims to evaluate the impact of untreated dental caries and its clinical consequences on the quality of life of Brazilian schoolchildren aged 8-10 years.

Methods: A randomly selected sample of 587 children underwent a clinical oral examination for the assessment of untreated dental caries and clinical consequences. The WHO criteria (decayed component of the decayed, missing, and filled teeth--D-DMFT in permanent teeth or d-dfmt in primary teeth) and the PUFA index, which records the presence of severely decayed permanent (upper case) and primary (lower case) teeth with visible pulpal involvement (P/p), as well as ulceration caused by dislocated tooth fragments (U/u), fistula (F/f), and abscesses (A/a), were used for the oral examination.
