Evolutionary Leap in Endodontics. Case report

Abstract

The Leap protocol combines the newest and most active association of reciprocal-rotary instrumentation, aluminum insert ultrasonic, and diode laser. The reciprocal-rotary technique consists of Niti instruments used in different motions depending on the stage of the treatment and promotes the balanced cutting effectiveness and reduced risk of fracture files. Moreover, it creates a centered and tapered shape. The aluminum tip for the ultrasonic unit delivers agitation, emulsification, and cavitation of antiseptic solutions that improve the cleaning. The dye and laser use cause the ablation and final disinfection. This paper describes the case of a patient with asymptomatic apical periodontitis in an upper first right molar submitted to endodontic treatment performed with Leap protocol. After conventional procedures, the root canals were prepared by using reciprocal-rotary instrumentation techniques. Between each file a new solution was placed and activated with the ultrasonic handpiece. At the end of instrumentation, the root canals were aspirated, dried with paper points, the indocyanine dye was placed into the root canals and, DaVinci laser was used for 30 seconds. The gutta-percha cones matching the final Niti file were used coated with AH Plus sealer. A periapical radiograph was taken to verify obturation and its anatomical complexity. Six months after the procedure, the patient was asymptomatic, and the radiographic examination showed healthy periradicular tissues. It is concluded that the use of Leap protocol in conventional endodontic treatment was effective, suggesting that this therapy may provide additional benefits to patients when compared to the conventional technique.

Tratamento Endodôntico em Pacientes Submetidos a Radioterapia: Revisão de Literatura

“…O segundo passo é a utilização de equipamentos para deixar o tratamento mais rápido e eficaz. Dentre os equipamentos disponíveis no dia-a-dia, independentemente do local de realização do tratamento, existem os localizadores foraminais, que oferecem maior precisão e agilidade na aquisição do comprimento real do dente, além dos instrumentos rotatórios, que, se empregados da forma correta, oferecem maior eficácia na limpeza mecânica dos canais e maior agilidade também, além de tecnologias para anestesia, radiografias digitais, tomografia computadorizada de feixe cônico, unidades de ultrassom, lasers, microscópios operacionais, conceitos 3D de obturação e selantes 100% inorgânicos (Camargo et al, 2021). É importante salientar que o número de sessões também é um fator de grande influência para que o tratamento seja atraumático, devendo ser sempre que possível em sessão única para dentes com polpa vital, e em mais de uma sessão, quando possível, para dentes com polpa necrosada (Ferraz et al, 2004;AlRahabi & Ghabbani, 2018).…”
