Healing of periradicular tissues at 1-24 months when retro-obturated with amalgam without zinc or MTA. Case report
##plugins.themes.bootstrap3.article.details##
OBJECTIVE: The purpose of this case
report with observational design, was
to identify the periradicular healing in a
24-month follow-up when using any of
this materials, amalgam without zinc or
MTA. METHODS: The sample consisted
of 22 upper anterior teeth from 19
patients, 6 male and 13 female. The
patients were attended in the period April
2000 - February 2002, in two different
clinics of Bogota, Colombia. Each
patient signed an informed consent
accepting to participate in the study.
The assignment to any of the two
groups of root end-filling materials was
randomized. Then, 11 teeth were filled
with MTA and 11 with amalgam without
zinc. RESULTS: It was found clinically
that one tooth filled with amalgam
without zinc was sensitive in
observations at first and third months.
Radiographically, one tooth filled with
amalgam without zinc showed
unsatisfactory healing when observed
at month 15. Four teeth filled with MTA
and two with amalgam without zinc
presented complete healing 6 months after retro-obturation. Seven patients
presented complete healing, nine filled
with MTA and two with amalgam without
zinc when observed at month 24.
CONCLUSIONS: Sensitive was
observed in teeth filled with amalgam
without zinc, while those filled with MTA were asymptomatic. Radiographically, surgeries carried out with MTA showed better and quicker bone neoformation in different evaluation periods.
