N o a p i c e c t o m y i n e n d o d o n t i c s u r g e r y Conclusion Zero apicectomy in endodontic surgery is a novel technique that combines high-resolution CBCT visualization of the apical situation with the use of efficient irrigation with EndoVac, root canal treatment and root surface condi- tioning in order to allow the preservation of the apical part of the root ad integrum. Pre- serving the total length of the root has many benefits, including, most importantly, the sta- bility and longevity of the tooth, as cutting the root exposes dentinal tubules. Since we per- form retrograde obturation of the main canal, we cannot guarantee that the exposed dentin is bacteria-free. Comparing this with other techniques, in which we drain the cyst for a certain period without having the ability to know in advance if surgery will be needed later, zero apicectomy clears the infection from inside the bone and treats the root canal in the same session, giving the body a greater opportunity to heal in a healthy, clean envi- ronment. Current literature has not described this technique; however, clinical cases have proven its success. Competing interests The authors declare that they have no compet- ing interests. References 1.
