Abstract :
Teeth with open apices, such as in immature teeth or those with apical root resorption are
clinical cases with difficult immediate resolution. With the use of mineral trioxide aggregate
(MTA) in dentistry, it was possible to optimize the treatment time of these cases by immediate
placement of apical plug and the root canal filling. However, some negative effects can occur
if MTA is extruded beyond the apex. To avoid this accident, it has been recommended to use
of an apical matrix prior to placement of MTA. This study reports two clinical cases of apical
plug placement in teeth with pulp necrosis and open apices. One case had an immature apex
due to dental trauma and the other case had apical resorption due to the presence of
endodontic infection in the root canal. MTA apical plug with approximately 4 mm thickness,
was placed in the apical zone of the root and immediately the canal was obturated with guttapercha
and endodontic sealer. Follow-up evaluations showed clinical and radiographic
evidence of success.
