“…Ultrasonic activation was carried out through a straight ultrasonic tip once the root canals were fully irrigated with 2.5% sodium hypochlorite and in conjunction with a reduced-power (20%) ultrasonic platform for 3 x 20s cycles. The results of this study, post-analysis of the level of GP remnants left upon root canal walls, demonstrated that the combinatory use of passive ultrasonic irrigation and Protaper or Reciproc systems were more effective than single-method approaches for GP removal (Gomes et al, 2017).…”

“…The use of ultrasonic tips for retreatment is reserved chiefly for stiff pastes/types of cement (Patel, 2016). However, the first study analysing the use of ultrasonic-based irrigation in conjunction with other GP removal methodologies, such as ProTaper or Reciproc, was described in 2017 by Gomes and colleagues (Gomes et al, 2017). This investigation probed the effectiveness of four different techniques -ProTaper alone, ProTaper + passive ultrasonic irrigation, Reciproc alone, and Reciproc + passive ultrasonic irrigationin removing GP from a total of 40 maxillary molars previously treated with root canal preparation/obturation.…”

Gaining a predictable outcome in endodontics is complicated by handling an endodontically treated. Compared to primary root canal therapy, non-surgical endodontic retreatment typically entails the removal of previous root filling materials. This process may be necessary to enable access to contaminated canal space for recleaning and to remove obturation materials that may have been contaminated by marginal penetration of microorganisms and microbial toxins. The achievement of patency at the canal terminus and the extension of cleaning as close as possible to the apical terminus have been identified as healing prognostic criteria. Gutta-percha (GP) is the current mainstay material utilised as an endodontic filling material, capable of performing comprehensive, three-dimensional sealing of the treated root canal system in a highly effective manner with considerable physical durability. Interestingly, since its initial discovery in the 17th century, GP remains to this day the ideal obturation material used across, in essence, all dental clinics globally due to its material properties and versatility for use in conjunction with sealer compounds. The development of GP removal systems that can manage to remove GP in its entirety from root canals during non-surgical retreatment procedures is currently highly desirable for dental practices. This literature review investigated this current research niche and scrutinised two prevalently utilised rotary systems – Edgefile-XR and the XP-Endo shaper systems.

“…Passive ultrasonic irrigation (PUI) is one of the most studied approaches for activating irrigating solutions in the literature and is based on a passive ultrasonic tip vibrating at ultrasonic frequency inside the root canal with an irrigation solution. Despite controversial results, most studies indicate better performances in the addition of this resource for removing filling materials remnants after initial bulk removal with NiTi preparation systems (Bueno et al, 2017;Gomes et al, 2017;Castro et al, 2018;Silveira et al, 2018;Crozeta et al, 2020). The influence of PUI on the outcome of secondary treatment is still unknown, the only study published on the subject to date is a retrospective clinical study that found higher survival rates in retreatments associated with PUI (Bartols et al, 2020).…”

O retratamento não cirúrgico é atualmente a terapia mais afetada na Endodontia em termos de desfecho clínico. O presente estudo tem como objetivo avaliar estratégias modernas para abordagens complementares na remoção de material de obturador. Assim foi realizada uma revisão narrativa da literatura nas bases de dados PubMed. Cochrane Library e Web of Science com as seguintes palavras-chave em diferentes ordens: “root canal”, “filling material removal”, “non-surgical retreatment” e “supplementary”. Para o delineamento da seleção de estudos, após a triagem dos títulos, foi realizada a retirada das duplicatas e aplicados os critérios de inclusão, em seguida foi feita a análise dos resumos e, por fim, realizada a revisão dos textos completos para seleção final dos estudos. Pesquisas adicionais foram conduzidas manualmente sob demanda. Seis tipos de estratégias de limpeza foram identificados na literatura para abordagem complementar em retratamento não cirúrgico: ativação ultrassônica e sônica passiva, ativação ultrassônica ativa, instrumentos plásticos para agitação mecânica, instrumentos metálicos para agitação mecânica, ativação multissônica e ativação a laser. Aqueles abordados na literatura têm sido associados a desempenhos mais elevados de remoção de material de obturador em comparação com sistemas de instrumentação apenas. No entanto, nenhum deles foi capaz de remover completamente o material obturador dentro do sistema de canais radiculares. Estudos clínicos controlados e randomizados são necessários para entender a real influência dessas estratégias no retratamento não cirúrgico. Há uma discrepância notável entre o volume de estudos para cada estratégia, mais estudos são necessários em alguns sistemas já contemplados. Ainda existem sistemas de ativação das soluções irrigadoras não elucidados no retratamento não cirúrgico.

“…Furthermore, another study concluded that mechanized systems cannot replace manual instrumentation, and that in comparison to other systems, it was not associated with iatrogenic errors (47) . Gomes et al (40) evaluated the effectiveness and the duration of obturation removal from a root canal with ProTaper and Reciproc with Passive Ultrasonic Irrigation (PUI), which was conducted with sodium hypochlorite for one minute. There were no significant differences regarding the obturation removal percentage from the root canal.…”

“…It includes nickel-titanium instruments with M-Wire alloy, which are more resistant to cyclic fatigue, torsional fatigue, have greater flexibility, and lower extrusion of debris than conventional alloys and continuous systems. It has a more effective performance than other reciprocating systems like WaveOne while maintaining the centrality of the root canal (13,17,(39)(40)(41) . One of the main advantages of reciprocating systems compared to other systems is the greater resistance to cyclic and torsional fatigue (12,20,42,43) .…”

Nonsurgical endodontic treatment is the first choice in case of endodontic failure. The first step of retreatment is root canal opening, which will enable the biomechanical preparation of the root canal with proper irrigation and disinfection. The obturation removal protocol includes manual files, solvents and Reciproc, a single-use reciprocating file. This review of the scientific literature addresses the specific characteristics of manufacture, kinematics and function of the instruments and chemical products used in this protocol. We found that the choice of manual files, xylol and Reciproc would allow for a simple, safe and effective opening of the root canal.
