RESULTS
The radiographic examinations demonstrated a resolution of the periapical lesion after 40 days (C).
A 3-year follow-up revealed radiographic evidence of bone healing (E).
CONCLUSION
The antimicromial and bioestimulation properties of ozone, proven by the literature,
have a great potencial to be incorporated to endodontic therapy, even in traumatized tooth.
