Prevalence of Bacteria of Genus Actinomyces in Persistent Extraradicular Lesions—Systematic Review
Abstract
:1. Introduction
2. Materials and Methods
2.1. Eligibility Criteria and Research Methodology
- Include all those studies that have identified Actinomyces on the external radiculatum surface of the dental roots in teeth with persistent lesions previously treated by means of endodontic therapy;
- Include all those articles that have identified bacteria in persistent endodontic lesions after retreatment with extraradicular involvement;
- Include all articles that have analyzed the presence of Actinomyces infections in endodontic lesions (secondary outcome);
- The exclusion criteria are to exclude all those studies and articles that deal only with case reports and reviews;
- Include articles performed on a population larger than twenty teeth;
- Exclude all those studies that did not search for the presence of Actinomyces in the endodontic setting and that do not report data on the prevalence or incidence of Actinomyces.
2.2. Screening Methodology
- (1)
- Primary outcome: number of teeth with the presence of a persistent extraradicular infection in which the presence of Actinomyces has been ascertained;
- (2)
- Secondary outcome: number of teeth with endodontic infection in which the presence of Actinomyces has been ascertained;
- (3)
- Tertiary outcome difference in the prevalence of bacteria of the genus Actinomyces between primary endodontic infections and secondary endodontic infections.
