Root resection and root amputation.

Abstract

Attachment loss in furcal areas is a challenge for the clinician. Root resection and root amputation techniques have been used to overcome the instrumentation problems that these areas pose. Recent reports indicate that this approach is effective and reliable but extremely technique-sensitive and expensive for endodontic and prosthetic involvement. A more conservative approach, such as scaling and root planing, is suggested only for shallow class II furcation. Guided tissue regeneration in deep class II and class III furcation seems to be unpredictable and the efficacy of this therapy in such areas is still questionable.

[The preparation of retrocavities in apicoectomies].

The purpose of this in vitro and in vivo study was to compare the quality of retrograde cavities and retrofilling using various retrograde techniques (microhead, ultrasonic). The quality was evaluated on the basis of dye penetration, macroscopic control, and both light microscopic and scanning electron microscopic examination. A total of 40 extracted teeth with a single canal were analyzed. The clinical result was evaluated in 25 patients with root-filled teeth and the indication of apicoectomy. Statistical analysis indicated that the seal was significantly better with ultrasonically prepared cavities than with microhead preparation. Retrofillings prepared ultrasonically also showed significantly fewer peripheral fissures. The scanning electron microscopic examination, however, demonstrated peripheral fissures in all filled teeth. Furthermore, the cavities prepared ultrasonically had a smoother surface and a lower smear layer. This preparation produced a more pleasing final result. The advantages of better accessibility during the preparation, namely, more precise preparation of the retrofilling and only minor substance loss were confirmed clinically. Using the ultrasonic equipment, absolutely sterile working conditions are present.

A scanning electron microscopic study of in vivo ultrasonic root-end preparations.

The purpose of this in vivo study was to evaluate root-ends for cracks after root resection and again after ultrasonic root-end preparation in patients undergoing endodontic surgery. Endodontic surgery was performed on 25 roots from 20 patients. In vivo vinyl polysiloxane impressions were made after root resection and again after ultrasonic root-end preparations. Epoxy resin casts were made from the impressions and scanning electron micrographic examination of the root-end replicas was performed. There was no evidence of cracks after root resection. One incomplete canal crack was evident after ultrasonic root-end preparation.
