Aim: This presentation aims to demonstrate the complete healing of apical
periodontitis in two cases shortly after non-surgical root canal retreatment.
Olgu 1: A 17-year-old healthy male was referred to the Department of Endodontics
of our institution with complaints of swelling around tooth 37(FDI) in the
mandibular posterior region, which had subsided to an asymptomatic condition
following inconsistent antibiotic administration. An insufficient root canal filling
was noted in tooth 37, accompanied by a significant periapical radiolucency.
Olgu 2: A 26-year-old healthy male patient was referred to the Department
of Endodontics of our institution for evaluation, presenting no complaints.
Incidentally, a significant periapical radiolucency associated with the apex of tooth
37 was observed in the X-ray assessment. Non-surgical root canal retreatments
were recommended for these two cases. Treatment Protocol: Traditional access
cavity preparations were performed under isolation and magnification (Densim
Optics, Slovenia). Primary root canal fillings were mechanically removed using
D-series instruments (Dentsply Maillefer; Ballaigues, Switzerland). After achieving
apical patency, glide path preparation and final shaping were carried out under
copious irrigation, respectively. An asymmetrical reciprocating instrumentation
ecosystem was preferred for mechanical shaping, and the final shaping size
was 45/05 in teeth (WaveOneGold, Dentsply Sirona). The final irrigation strategy
consisted of 10 ml of sodium hypochlorite with a 5-minute contact duration and 5
ml of ethylenediaminetetraacetic acid with a 2-minute contact duration for each
root canal, respectively. Calcium hydroxide paste was dressed in the canals for 14
days. Subsequent visit involved sealing the root canals using cold gutta-percha
cones and bioceramic-based paste.
Results: During the 6-month follow-up of the cases, complete resolution of the
periapical lesion was observed with increasing trabecular bone density. Also,
functionality was maintained with no symptoms.
Conclusion: In two young adult cases, it is demonstrated that non-surgical
retreatment of root canal therapy, performed in accordance with fundamental
endodontic principles, can achieve complete healing of apical periodontitis within
a short follow-up period (6 months).
