Area of Science:

Endodontology
Microbiology
Infectious Diseases

Background:

Persistent endodontic infections represent a significant clinical challenge.
Understanding the microbial landscape is crucial for effective treatment strategies.

Purpose of the Study:

To systematically map the existing evidence on the microbiota associated with persistent endodontic infections.
To identify prevalent microbial species and factors influencing their presence.

Main Methods:

A comprehensive scoping review was conducted.
Searches were performed across multiple major scientific databases.
Eligibility criteria focused on clinical studies evaluating microbial profiles in teeth undergoing endodontic retreatment.

Main Results:

32 studies were included, identifying a polymicrobial profile.
Key species include Enterococcus faecalis, Parvimonas micra, and Porphyromonas species.
Symptomatology, inadequate root canal filling, and poor coronal restoration were linked to increased microbial load and specific species.

Conclusions:

Persistent endodontic infections are characterized by a polymicrobial community.
Current detection methods have inherent limitations.
Clinical factors like restoration quality significantly impact the endodontic microbiome.
