Summary
This study introduces a new six-tiered classification for lateral gingivobuccal defects after oral cancer surgery. This system aids in standardizing defect documentation and guiding reconstructive flap selection for better patient outcomes.
Area of Science:
- Oral surgery
- Oncology
- Reconstructive surgery
Background:
- Lateral gingivobuccal defects are common after oral cancer resection.
- Standardized classification systems are needed for defect documentation and treatment planning.
Purpose of the Study:
- To propose a novel six-tiered classification system for lateral gingivobuccal defects.
- To standardize the description of defect depth and tissue involvement.
- To guide the selection of reconstructive flaps.
Main Methods:
- Development of a six-tiered classification system based on anatomic depth and tissue layers.
- Classification includes partial-thickness (Classes 1-3) and full-thickness (Classes 4-6) defects.
- Defect categories range from no bone involvement to segmental bone resection.
Main Results:
- The proposed classification system categorizes defects from simple mucosal defects to complex full-thickness defects involving segmental bone resection.
- It differentiates between partial-thickness and full-thickness defects based on skin involvement.
- The system progresses through increasing severity of bone involvement within each thickness category.
Conclusions:
- The novel classification system provides a standardized framework for describing lateral gingivobuccal defects.
- This system can facilitate multicenter research and improve communication among clinicians.
- It aims to optimize reconstructive flap selection for improved surgical outcomes.

01:15Teeth
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 and...

01:21Tooth Anatomy
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 grinding food.
