- Traumatic injuries to the teeth - R. R. Welbury and J. M. Whitworth
12.1 EPIDEMIOLOGY
Dental trauma in childhood and adolescence is common (657HFig. 12.1). At 5 years of age
31-40% of boys and 16-30% of girls, and at 12 years of age 12-33% of boys and 4-
19% of girls will have suffered some dental trauma. Boys are affected almost twice
as often as girls in both the primary and the permanent dentitions.
The majority of dental injuries in the primary and permanent dentitions involve the
anterior teeth, especially the maxillary central incisors. Concussion, subluxation, and
luxation are the commonest injuries in the primary dentition (658HFig. 12.2), while
uncomplicated crown fractures are commonest in the permanent dentition (659HFig. 12.3).
Prognosis of traumatic injuries has improved significantly in the last 20 years. This
has been largely due to a greater understanding and knowledge of pulpal procedures.
