Summary
The dentogingival complex (DGC) dimensions vary significantly across different gingival biotypes. Thin biotypes exhibit larger DGC dimensions compared to mixed and thick biotypes, impacting dental procedures.
Area of Science:
- Periodontology
- Restorative Dentistry
- Dental Anatomy
Background:
- Understanding dentogingival complex (DGC) dimensions is crucial for successful restorative dentistry.
- Gingival biotype, a characteristic of soft tissue thickness, is known to influence various periodontal and restorative outcomes.
Purpose of the Study:
- To estimate the dentogingival complex (DGC) dimensions.
- To determine if DGC dimensions differ based on gingival biotype (thin, mixed, thick).
Main Methods:
- A cross-sectional study involving 53 participants requiring restorative crowns.
- Gingival biotype was classified as thin, mixed, or thick based on transparency using a periodontal probe.
- Dentogingival complex (DGC) dimensions were measured via transsulcus probing at mesial, medial, and distal sites.
- Statistical analysis included descriptive statistics and Friedman test to compare DGC dimensions across biotypes and sites.
Main Results:
- Mean DGC dimensions varied across sites: mesial (3.09 mm), medial (3.40 mm), and distal (2.70 mm).
- Mesial sites consistently showed greater DGC dimensions than medial and distal sites across all biotypes (p<0.05).
- Thin gingival biotypes presented significantly larger DGC dimensions compared to mixed and thick biotypes at all measured sites (p<0.001).
- Conversely, thick biotypes exhibited the smallest DGC mean dimensions.
Conclusions:
- Dentogingival complex (DGC) dimensions are significantly influenced by gingival biotype.
- The findings align with existing literature on DGC dimensions.
- Recognizing these variations is essential for tailoring dental treatments to specific gingival biotypes.

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...
