case_images: A healthy 18-year-old female patient reported to our dental clinic with a complaint of pain and swelling in her upper left lateral incisor [Figure 1].
case_images: Radiograph shows presence of an invagination along the entire length of the root (white arrow). The white object in the image is the patient's nose ring which was difficult to remove when taking the radiograph.

case_images: The two canals were negotiated, and working length was established using radiography [Figure 3]. The two canals were prepared to working length by step back technique to a size 55 K file (Master apical file, Mani Inc, Tochigi, Japan) and to a size 80 K file (Final file, Mani Inc, Tochigi, Japan); the canal was then flared by using Gates Glidden drills sizes 1-4 (Maillefer-Dentisply, Baillagues, Switzerland).
case_images: Post-obturation radiograph shows a dentine bridge along the entire length of the root canal (white arrow).

case_images: CBCT (KODAK 900 cone beam CT digital X-ray) scan of the maxilla was taken and a three dimensional reconstruction of the involved tooth was done [Figure 8].
case_images: Three dimensional reconstruction of the involved tooth shows developmental groove along the entire length of the root, both labially and palatally (white arrows).
