Endodontic treatment associated with photodynamic therapy: Case report.
BACKGROUND
The complete elimination of bacteria inside the root canal is a difficult task, and inconsistent removal of the innermost layer of contaminated dentin leaves bacteria behind. PDT is an adjunct to conventional endodontic treatment due to its potential to reduce bacteria and its biocompatibility.


OBJECTIVE
Report a case of endodontic treatment associated with Photodynamic Therapy (PDT).


METHODS
A patient with chronic dentoalveolar abscess with radiolucent lesion next to the apexes of teeth 11 and 21 was submitted to conventional endodontic treatment associated with PDT. The canals were filled after two PDT sessions with an interval of 15days between applications.


RESULTS
After six months, total regression of apical periodontitis and no fistula or associated symptoms were observed.


CONCLUSIONS
The treatment proposed is a viable option for the clinician as it is easy to perform, has relatively low-cost and allows the improvement of symptoms in a short period of time.
