The introduction of microinstruments for root‐end cavity preparation has clearly improved the surgical technique in periradicular surgery with apicectomy. The new generation of sonic and ultrasonic root‐end preparation devices, usually termed ‘retrotips’, has simplified the preparation of a sufficiently deep cavity that follows the original path of the root canal. The present paper describes the use of a new set of diamond‐surfaced retrotips driven by a sonic handpiece. For clinical evaluation a prospective study was carried out, with assessment of pre‐, intra‐ and postoperative data in 50 teeth (43 patients). This paper analyses: (i) the applicability of the new retrotips; (ii) the quality of the root‐end filling assessed radiographically; (iii) the immediate postoperative course. Access with the retrotips to the resected root‐end was found to be excellent in 80% of the treated teeth. The postoperative radiographs showed a root‐end filling of at least 3 mm in 70% of the resected teeth. Healing was uneventful in all cases and most patients presented without any symptoms after 5 days and 10 days. The long‐term treatment outcome will be reported in a future paper.
