Abstract:
Treatment of the entire root canal system is essential for the success of root canal treatment. Thus, it is necessary for the clinician to know the root canal anatomy of the human dentition and its variations. This case report describes a patient with double palatal roots on the maxillary right second molar. Meanwhile, her maxillary left second molar had, asymmetrically, only 1 palatal root. Though the possibility of 2 palatal root canals in the maxillary second molars is scarce, it should be taken into account during endodontic treatment to guarantee successful treatments.

Tooth Anatomy
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 grinding food.
Teeth
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 and...
