Influência dos acessos endodônticos minimamente invasivos na desinfeção canalar

Abstract

Introduction: Microorganisms have been highlighted as the main cause of pulpar and periapical diseases. The complexity of root canals requires mechanical instrumentation and effective irrigation to reduce the number of microorganisms present in the canals. Therefore, the aim of this review is to analyze the scientific literature and seek evidence that supports (or not) a relationship between the type of endodontic access cavity performed and canal disinfection. Materials and Methods: The protocol for this systematic review is registered on the PROSPERO platform with the ID code CRD42024519265. The research was conducted in the following databases: PubMed/MEDLINE, Cochrane, Web of Science, and Scopus. Study selection was performed according to the PICO research question and following PRISMA guidelines. The quality assessment of the studies was carried out using the QUIN tool. Various data were collected from the studies, including: author; year; title; study type; objectives; sample size; sample characteristics; types of access cavities; bacterial culture; disinfection; and results. The most important data from each study were analyzed and compared. Results: The search in the mentioned databases resulted in a total of 1411 articles. After analyzing the articles, 7 articles were selected to be included in the systematic review. From these articles, we found that the most frequently used minimally invasive endodontic access cavity was the conservative cavity, and the most commonly used disinfecting agent was sodium hypochlorite. Conclusion: The use of traditional endodontic access cavities results in a greater reduction of intracanal bacteria, and the best method for canal disinfection is the combination of NaOCl irrigant with laser. More studies are needed to confirm the effectiveness of laser and passive ultrasonic irrigation, as well as studies evaluating truss access cavities and ninja/ultraconservative cavities.
