Does dental trauma in the primary dentition increases the likelihood of trauma in the permanent dentition? A longitudinal study
Abstract
Objectives
The
aim of this longitudinal study was to assess the likelihood of children
suffering traumatic dental injuries in the permanent dentition
subsequent to traumatic dental injuries in their primary dentition.
Materials and methods
A
longitudinal study was conducted in Pelotas, Brazil. Children were
assessed in 2007, when they were aged 2–5 years, and in 2013, at which
time, they were aged 8–11 years. Data collection included interviews
with parents and clinical oral examination for dental trauma and
occlusion. The classification proposed by Andreasen and Andreasen was
used, and crown discoloration and fistula were added to this criterion
in order to assess pulp involvement. Child/parent report was used to aid
in the diagnosis of both treated and untreated injuries. As a
limitation, no radiographs were taken. Descriptive, univariate, and
multivariate logistic regression analyses were performed.
Results
A
total of 110 children were included. Dental trauma frequency in the
primary dentition was 38.2% and that in the permanent dentition was
30.9%. In the multivariate analyses, children with dental trauma in the
primary dentition showed a higher likelihood of suffering dental trauma
in the permanent dentition [odds ratio (OR) 2.97, 95% confidence
interval (CI) 1.01–8.91, P = 0.05].
Conclusions
Individuals
with previous trauma in the primary dentition are prone to further
trauma in the permanent dentition. The history of dental trauma may be
used to predict dental trauma in the permanent dentition and to
establish preventive measures.
Clinical relevance
Behavioral
characteristics may be related to the risk of a child suffering
injuries. The results suggested that some children are accident-prone.
