Objective: To evaluate the clinical efficacy of polycarboxylate cement as retrograde filling material.
Design: A prospective clinical study was made of 25 patients subjected to periapical surgery with ultrasound and
magnifying loupes, in which polycarboxylate cement was used as retrograde filling material. Measurements were
made of the area and diameter of the lesions pre- and postoperatively, and 6 and 12 months after the operation.
The apical resection and retrograde filling areas were also measured, and the prognosis following surgery was
Results: A total of 23 patients with 31 apicoectomized teeth were studied (2 patients being lost to follow-up). The
mean area of the periapical lesions before surgery was 52.25 mm2, with a mean major diameter of 6.1 mm and
a mean lesser diameter of 4.8 mm. The success rate after 12 months was 54.7%, according to the criteria of Von
Arx and Kurt. The prognosis was poorer in females, in larger lesions, and in cases with larger retrograde filling
Conclusions: Polycarboxylate cement offers good results, with important bone regeneration after periapical surgery.
