Endodontic treatment is a fundamental dental procedure performed to maintain the
function of a tooth in cases where the dental pulp is infected or irreversibly damaged.
This procedure is predicated upon the complete removal of the affected pulp tissue,
appropriate shaping and disinfection of the root canal system, and subsequent sealing
with a hermetic obturation. However, inadequate cleaning, erroneous diagnosis,
insufficient disinfection, and mechanical errors may lead to treatment failures, which
manifest as periapical pathologies and persistent clinical symptoms. In the context of
retreatment, the complete removal of existing obturation materials (e.g., gutta-
percha, canal posts) by means of mechanical, chemical, and ultrasonic techniques;
the re-instrumentation and disinfection of the canal; and the final obturation with an
impermeable filling material are critical steps in determining treatment success.
Additionally, the effective combination of irrigant solutions (such as NaOCl and
EDTA) plays a pivotal role in eliminating smear layer and bacterial contaminants. In
light of the extant literature, accurately identifying the primary causes of endodontic
treatment failure underscores the necessity for the development of multidisciplinary
and individualized treatment strategies. In retreatment procedures, the complete
removal of previous obturation materials, the effective disinfection of the root canal
system, and the establishment of a hermetic seal are regarded as indispensable factors
for ensuring long-term treatment success. This review emphasizes that meticulous
management of factors during the preoperative, intraoperative, and postoperative
phases is imperative to promote periapical healing and overall treatment efficacy.
Future long-term prospective studies are expected to contribute significantly to the
detailed assessment of current protocols and the establishment of standardized
guidelines.
