“…14 In many previous studies, the predominant place of injury occurrence in school-aged children was home, followed by school and other public places. 9,13,21,22 In the present study, most injuries occurred at school. The second and third most common places of occurrence were home and cycling paths, respectively.…”

“…This finding is in agreement with most other studies of traumatic dental injury in children. 7,[11][12][13][14][15][16][17][18][19][20] In a study of New Zealand children, fall was the most common cause in children aged 5 to 7 years, but collision became more common in the 8-to 10-year-old group. 21 Nonetheless, such a trend was not observed in this study.…”
