Summary
Restorations and fixed prostheses are compatible with periodontal health when oral hygiene is maintained. Proper diagnostic criteria and contemporary techniques are essential for successful outcomes and preventing periodontal disease.
Area of Science:
- Dentistry
- Periodontology
- Prosthodontics
Background:
- Periodontal health is crucial for the longevity of dental restorations and prostheses.
- Understanding the impact of restorative margins and materials on periodontal tissues is essential.
Purpose of the Study:
- To systematically review and evaluate literature on periodontal outcomes of restorations and tooth-supported fixed prostheses.
- To synthesize findings regarding the relationship between restorative procedures and periodontal health.
Main Methods:
- A systematic literature search of PubMed was conducted.
- Included were various study types (reviews, trials, meta-analyses) in English.
- Data was synthesized narratively and organized by restoration type and preparation design.
Main Results:
- Subgingival margins can increase gingival inflammation and probing depth, but intracrevicular margins alone do not cause disease.
- Large overhangs are linked to inflammation and bone loss for both direct and indirect restorations.
- Gingival displacement can cause recession; finish line design differences showed no significant periodontal impact.
Conclusions:
- Modern restorative procedures and materials are periodontally compatible with good patient hygiene.
- Thorough periodontal assessment is vital before planning fixed restorative treatments.

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...

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...

3.2K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
