Acesso cirúrgico minimamente invasivo : revisão de literatura.

Abstract

Endodontic treatment has advanced with the introduction of minimally invasive techniques aimed at maximizing the preservation of healthy dental structure. This study conducted a literature review to explore the advantages and challenges of minimally invasive endodontic access (MIECs) compared to traditional techniques, considering the adoption of the technique by professionals and undergraduate students. The access cavity is crucial for the success of endodontic treatment, allowing for adequate instrumentation, irrigation, and obturation of root canals. Traditionally, the approach focused on a broad and direct access, but it removed a significant amount of dentin, increasing the risk of fractures. MIECs seek to reduce this dentin loss and improve the tooth's resistance by using advanced technologies, such as operating microscopes and ultrasonics. Despite evidence suggesting that MIECs can promote structural preservation and reduce future complications, the review found that widespread adoption of the technique faces significant practical challenges. The need for specific equipment and proper training represents barriers for many dental professionals and students. Furthermore, long-term studies are still insufficient to definitively confirm the benefits of MIECs regarding the durability and resistance of treated teeth. It is concluded that, although promising, the minimally invasive access technique should be adopted cautiously and utilized with adequate training and technological availability to ensure a balance between tooth preservation and therapeutic effectiveness.
