Improved single visit management of old infected iatrogenic root perforations using Biodentine®
Volume 32, Issue 1, June 2018, Pages 17–24
Abstract
Aim
The
aim of this retrospective observational case series study was to
evaluate the middle term outcomes on endodontic management of old
infected iatrogenic root perforations using Biodentine. The treatments
were always concluded in a single visit, without previous medication
with calcium hydroxide. Our goal was to facilitate this kind of
treatments and to make them more reproducible and manageable even for a
general practitioner or a student.
Methodology and methods
Between
January 2011 and June 2016, 51 patients with old infected root
perforations have been enrolled. All the treatments were performed using
Biodentine in a single visit. Infected root perforation repair was
performed by supervised dental students (39%) or a qualified endodontist
(61%), employing surgical microscope magnification during treatments.
After the treatment, the 51 patients were monitored for 18–64 months. We
used clinical and radiographic examinations.
Results
Of
51 examined teeth, 48 (94%) were classified as healed. The time, the
size and the location of the perforations did not have a significant
effect on the outcome. We proved the ineffectiveness of the null
hypothesis. According to this latter, the single visit treatment of old
infected perforations with Biodentine was inadequate.
Conclusions
In
single visit treatments, Biodentine seems to provide a biocompatible
and effective seal in acidic environment, in accidental root
perforations, even if the treatment is performed by an inexperienced
operator and regardless of the location, the size and the time of
occurrence of the perforation.
