Crown discoloration
Although these Guidelines recommendations focus
on the management of acute dental injuries, crown
discoloration may be considered as it is a frequently
asked question by the parents or carers, mainly
for esthetic reasons. Discoloration is a common complication
after luxation injuries (47–50). Such discoloration
may fade, and the tooth may regain its
original shade (8, 47, 50, 51). Teeth with persisting
dark discoloration may remain asymptomatic clinically
and radiographically or they may develop apical
periodontitis (52, 53). There is an association
between crown discoloration and pulp necrosis in
traumatized primary teeth (48, 54). Unless associated
infection exists, root canal treatment is not indicated
