Overview of Regeneration and Repair

Overview of Regeneration and Repair

Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Teeth

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...

Summary

This summary is machine-generated.

Regenerative endodontic procedures (REPs) show limited evidence for pulp regeneration in irreversible pulpitis (IP). While biologically plausible, vital pulp therapy (VPT) remains the preferred method for pulp preservation in these cases.

Area of Science:

Endodontics
Regenerative Dentistry
Dental Materials Science

Background:

Regenerative endodontic procedures (REPs) are increasingly utilized for pulpal pathologies, especially in immature teeth.
Bioactive calcium silicate materials have advanced vital pulp therapy (VPT) and REPs.
Current diagnostic criteria for irreversible pulpitis (IP) may overestimate pulp damage, as some pulps retain regenerative capacity.

Purpose of the Study:

To conduct a scoping review evaluating evidence for using REPs to preserve and regenerate vital pulp tissue in teeth diagnosed with IP.

Main Methods:

A comprehensive literature search was performed across multiple databases (MEDLINE, Web of Science, Cochrane Library, Scopus, Google Scholar).
Manual citation searching was also conducted to ensure thorough literature coverage.
Studies were selected based on predefined inclusion and exclusion criteria.

Main Results:

Four case reports showed moderately successful pulp regeneration with REPs in immature permanent teeth with IP.
Two case series and two case reports indicated comparable outcomes using REPs in mature permanent teeth with IP.

Conclusions:

Clinical evidence supporting REPs for pulp regeneration in teeth with IP is currently limited.
The biological basis for REPs in IP is conceptually strong, warranting future research.
Vital pulp therapy (VPT) is currently the recommended approach for pulp preservation in teeth diagnosed with IP.
