Factors
affecting the long-term results of endodontic
treatment.
Sjogren U, Hagglund
B, Sundqvist G, Wing K.
The influence of various factors that may affect the outcome of root canal
therapy was evaluated in 356 patients 8 to 10 yr after the treatment. The
results of treatment were directly dependent on the preoperative status of the
pulp and periapical tissues. The rate of success for
cases with vital or nonvital pulps but having no periapical radiolucency exceeded
96%, whereas only 86% of the cases with pulp necrosis and periapical
radiolucency showed apical healing. The possibility
of instrumenting the root canal to its full length
and the level of root filling significantly affected the outcome of treatment.
Of all of the periapical lesions present on
previously root-filled teeth, only 62% healed after retreatment.
The predictability from clinical and radiographic signs of the
treatment-outcome in individual cases with preoperative periapical
lesions cases was found to be low. Thus, factors which were not measured or
identified may be critical to the outcome of endodontic
treatment.
