Jp. Delattre et al., DENTAL INJURIES AMONG SCHOOLCHILDREN AGED FROM 6 TO 15, IN RENNES (FRANCE), Endodontics & dental traumatology, 11(4), 1995, pp. 186-188
A representative sample of 2020 schoolchildren, aged 6 to 15 years, wa
s randomly selected from 85 state and private schools in Rennes and di
stributed in 10 groups, according to their age. Type and prevalence of
dental injuries were determined in each group, using Ellis and Davey'
s classification, giving rise to a subset of 345 subjects. Simple enam
el fracture was the predominant injury (59.4%), occuring most often on
maxillary central incisors. Most time (77.1%), the trauma affected on
ly one tooth. Mean prevalence of dental injuries was 13.6% from 2020 s
ubjects. Boys showed a higher prevalence than girls (respectively 17%
and 10.2%), but this difference was only significant for age-groups 12
and 13 (p<0.001) and for the whole group of 6-15 (p<0.001).
