Summary
A rare case of double root canals in a maxillary lateral incisor was successfully retreated. This highlights the importance of recognizing root canal anatomy variations for effective dental treatment and symptom resolution.
Area of Science:
- Endodontics
- Dental Anatomy
- Radiology
Background:
- Maxillary lateral incisors typically have a single root and canal.
- Anatomical variations like double roots and canals are rare but can cause persistent dental symptoms if missed.
Purpose of the Study:
- To report a case of endodontic retreatment for a maxillary lateral incisor with a missed double root canal.
- To emphasize the diagnostic challenges and management of root canal anatomical variations.
Main Methods:
- Cone beam computed tomography (CBCT) identified double roots and canals in a maxillary lateral incisor with chronic apical periodontitis.
- The patient underwent root canal retreatment, including negotiation and obturation of the previously untreated palatal canal.
Main Results:
- Successful resolution of symptoms after retreatment of the maxillary lateral incisor.
- No recurrence of discomfort reported during a 1-year follow-up period.
Conclusions:
- Accurate diagnosis of root canal anatomy variations is crucial for successful endodontic treatment.
- Techniques such as CBCT imaging and careful examination are essential to identify missed canals and improve treatment outcomes.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
