Comparação da eficiência de corte e remoção de smear layer de instrumentos endodônticos rotatórios e reciprocantes: uma revisão de literatura

Abstract

INTRODUCTION: Endodontics is a dental specialty that deals with the pulp tissues and the periapical tissues of the teeth. Decontamination is one of the most critical challenges in endodontics, as it is essential for the success of the treatment. Mechanical movements are crucial for effective root canal decontamination, as they help clean the canal walls and remove pulp tissue and bacteria present inside the canal. OBJECTIVES: To evaluate the cutting efficiency, cleaning, and smear layer removal of rotary and reciprocating mechanized files in permanent teeth. METHODOLOGY: This is a literature review on the "Comparison of Cutting Efficiency and Smear Layer Removal of Rotary and Reciprocating Endodontic Instruments," gathering current and relevant information on the subject to present therapeutic approaches that optimize endodontic treatment and prevent potential iatrogenesis, based on well-selected and relevant scientific articles. RESULTS: The choice between rotary and reciprocating instruments can be based on additional criteria such as user comfort and cost, as performance efficacy did not show significant variations. CONCLUSION: This study concluded that, when comparing the efficacy of cutting and Smear Layer removal using various rotary and reciprocating endodontic instruments, all evaluated instruments delivered similar results in terms of cutting efficiency and smear layer removal.
