Abstract:
This case report presents a maxillary third molar with a C-shaped canal system. This is the first known description of a maxillary third molar with C-shaped anatomy. This unique pulp chamber morphology was observed under the operating microscope. Root canal treatment consisted of cleaning and shaping combined with ultrasonic irrigation with sodium hypochlorite. A calcium hydroxide dressing was applied between appointments. Obturation of the root canal system was performed with warm vertical condensation. The complexity of this canal morphology requires the prudent clinician to perform strict measures to achieve satisfying results.

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...
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.

Oral Cavity
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...

Conformations of Cyclohexane
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal tetrahedral value,...
