Abstract:
This article presents a comprehensive approach to reconstructing lateral gingivobuccal defects following oral cancer resection. The authors propose a novel six-tiered classification system based on anatomic depth and tissue layers involved: Classes 1 to 3 address partial-thickness defects (mucosa ± muscle), progressing from no bone involvement (class 1) to marginal/upper alveolar (class 2), and segmental bone resection (class 3). Classes 4 to 6 address full-thickness defects (including skin), similarly progressing through no bone, marginal/upper alveolar, and segmental bone resection. The classification aims to standardize documentation, facilitate multicenter research, and guide flap selection.

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...

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.
