A case is presented in which pulp capping was performed on a right first mandibular primary molar in a 7-year-old male patient. An alkaline cement powder based on mineral trioxide aggregate (MTA) was used for pulp capping. There were no pathological findings either on a radiograph taken after one year or on clinical examination after 18 months, and the right first mandibular primary molar remained vital after capping with MTA. Further clinical investigation of MTA for direct pulp capping of primary teeth should be performed.

Because of the frequency of dental injuries during infancy and adolescence, traumatized teeth with variable long-term prognoses present a problem for orthodontic treatment planning. Orthodontic therapy can remain unaffected, or be complicated, by traumatized teeth. In some cases, following dental injury, orthodontics can also be used to enhance (prosthetic and) restorative treatment results. The orthodontic challenges involved in treating patients with a history of dental trauma are complicated by the consequences of trauma on dentition development and the different treatment options that must be considered. In this paper, we provide actual examples of the effects dental trauma can have on orthodontic treatment planning.
