Utilization of gutta‐percha for retrograde root fillings

Abstract

Just as gutta-percha used with a root canal sealer is a recommended material for orthograde root fillings, it could similarly be the material of choice for retrograde fillings. Unfortunately, clinical accessibility and visibility do not always facilitate such a technique. The aim of this article is to present a new technique which enables retrograde fillings to be achieved with gutta-percha and a sealer. After the apex had been resected, a hole was drilled perpendicular to the plane of section of the apex about 1 mm coronally. The bucco-lingual depth required to reach the main canal was calculated. The cavity was then dried, coated with the sealer, and obturated with gutta-percha in accordance with thermo-mechanical compaction techniques. After excess filling material had been removed, the gutta-percha was cold burnished and the angles of the root were smoothed. Clinical cases illustrating healing of the periapical tissues are shown.

Randomized clinical trial of root‐end resection followed by root‐end filling with mineral trioxide aggregate or smoothing of the orthograde gutta‐percha root filling – 1‐year follow‐up

“…Gutta-percha (GP) has for decades been the first choice material for orthograde root fillings but has only rarely been used as a root-end filling material (Amagasa et al 1989, Sauveur et al 1997, 2000. It has been discussed whether a root-end filling after rootend resection is necessary, or if the root canals are sufficiently filled with GP (Nordenram & Svärdström 1970, Johnson 1999.…”

“…21 Birçok çalıĢma, periapikal kemik doku iyileĢmesinin kök ucu rezeksiyonundan sonra herhangi bir retrograd dolgu yerleĢtirilmesinden bağımsız olduğu sonucuna varmıĢtır. 22,23 Bazı araĢtırmacılar ise GP ile yapılan kök kanalı dolgularının rezeksiyon iĢlemi sonrasında ek bir dolguya gerek kalmayacak düzeyde rezeksiyon alanında tıkanma sağladığını iddia etmektedirler. 24 Bu sonuçlar, bu çalıĢmada kontrol grubu olarak ele alınan GP ile doldurulmuĢ kanallarda yapılan rezeksiyon iĢlemi sonrası elde edilen sonuçlar ile korelasyon göstermektedir.…”

Current strategy for successful periradicular surgery

“…In addition, several newer materials are currently used for periradicular surgery (51)(52)(53)(54)(55). These materials include amalgam, ethoxybenzoic acid (Super EBA), intermediate restorative material (IRM), and composite resin.…”
