– 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.
