Consequences of dental trauma to the primary teeth on the permanent dentition

Resumo

Dental trauma to primary teeth or to the jaws may
cause disorders on the development of permanent successor teeth.
The alterations may either occur at the time of accident or be caused
by post-traumatic consequences. Objective: The aim of this paper
is to present cases of alterations on permanent dentition following
dental trauma to primary teeth. Case reports: Three cases are
presented in this paper. The severity of the post-traumatic sequels
shown by the permanent teeth kept a direct relationship with the
extent of the impact and patient’s age at the accident. These sequels
resulted in whitish or brownish opacities, enamel hypoplasia, root
dilacerations, and total arrest of root development. Conclusion: It
can be concluded that the protocols for patients who had experienced
dental trauma must observe a systematic clinical and radiographic
follow-up as well as alternatives of treatment for the primary and
permanent teeth involved. Prognostics and treatments related to the
sequels in permanent teeth may be obtained from a close analysis
of clinical and radiographic aspects, avoiding more damages to the
stomatognathic system. The severity of the sequels is directly related
to the degree of permanent tooth formation (child’s age), type of
dental trauma and extent of the impact.
