Background: High success rate has been reported widely with conventional endodontic. When failure occurs, re-treatment alone or with surgical endodontics is the recommended treatment.

Objective: To compare the treatment outcome following apicectomy techniques, apicectomy with and without retrograde root – end filling.

Methods: Fifty three patients presenting with clinical and radiological evidence of pulpal and periapical pathology >5mm that will require apicectomy were randomly recruited into the study groups A or B over a period of 12 month. In group A apicectomy was performed without root - end filling and in group B apicectomy was performed with root – end filling. Patients were recalled 12 months and assessed clinically and radiologically.

Results: 35 out of 53 recruited patients reported for 12 month re-call visit. Two were excluded because of missing baseline radiographs. 33 patients that reported at 12months recall visit with complete radiographs were used for analysis. Patients age ranged from 16 – 66 years, with those in age group 21 – 30 years predominant, Majority (57.6%) were males. Forty teeth were treated, 14 had root – end filling and 26 without root – end filling. Maxillary incisors were the most frequently apicectomized teeth. 32 (80%) out of 40 apicectomized teeth were successful, 14 (88.5%) out of 26 teeth treated without root end filling were successful, while 9 (64.3%) out of 14 teeth treated with apicectomy with retrofil were successful.

Conclusion: Though apicectomized teeth without root-end filling had a higher percentage of success it was not statistically significant (p=0.15).

Apicectomy is the excision of the apical portion of the tooth and the attached soft tissues during periapical surgery.1 It is the most common surgical endodontic therapy procedure, it often involves periapical curettage, root-end resection, root-end preparation and root-end filling2 . Endodontic therapy is performed to maintain pulp vitality or treat necrotic pulp to maintain the tooth in the arch, thereby maintaining arch integrity.

Despite high success rates of conventional endodontic approach, failures still occur due to inadequacies in cleaning, shaping, obturation, iatrogenic events and loss of coronal seal. When failure occurs, re-treatment rather than extraction of teeth has been advocated. Re-treatment usually involves conventional (nonsurgical) or surgical endodontic approach.

When appropriate, conventional, nonsurgical retreatment efforts are directed to target deficiencies or repair of pathogenic and iatrogenic defects. Nonsurgical management of endodontic failures have recorded high success rates and is favored due to less discomfort and morbidity in comparison with periradicular surgery.4 However, when periradicular lesions with diameter>5mm4 are present, lower success rates have been recorded with non-surgical approach. Surgical endodontic management of periradicular lesions is resorted to when conventional endodontic therapy is not indicated, impossible or unsuccessful5 . Traditionally, apicectomy procedure involves placing a root-end filling following apical resection which is favored by some authors, 6,7,8 while others9,10 support adequate cleaning and obturation of the canal, followed by apical resection without root-end filling as the treatment of choice. However, evidence in support of both schools of thought remains equivocal. The aim of this prospective study therefore was to compare the treatment outcome following the two apicectomy techniques: apicectomy with and without retrograde root-end filling, with a view to evaluate the technique with better prognosis.
