Only a few studies have analyzed the influence of
orthodontic treatment on pulpal vitality of previously
traumatized teeth.14–16 However, to our knowledge, no
previous study has examined pulpal vitality in teeth
suffering dental trauma during orthodontic treatment.
The aim of the present study was, therefore, to examine pulpal vitality in permanent upper incisors suffering dental trauma during orthodontic therapy with
fixed appliances. A further objective was to assess the
influence of different parameters, such as type of trauma, type of incisor, orthodontic treatment time before
and after dental trauma, archwire exchanges per
month during orthodontic treatment after trauma, and
degree of pulp obliteration after trauma.
