dc.description.abstractA fratura de instrumentos endodônticos constitui uma intercorrência relevante no tratamento endodôntico, com potencial de comprometer a desinfecção do sistema de canais radiculares e influenciar o prognóstico terapêutico. O presente estudo teve como objetivo analisar, por meio de revisão de literatura, as principais estratégias diagnósticas e terapêuticas relacionadas ao manejo dessa complicação, incluindo abordagens conservadoras, cirúrgicas e o impacto das tecnologias contemporâneas no planejamento clínico. Trata-se de uma revisão de literatura realizada nas bases de dados PubMed e SciELO, utilizando o descritor “Instrument fractures and endodontic treatment”, com inclusão de estudos publicados entre 2015 e maio de 2026, nos idiomas inglês e português, sendo a análise baseada em leitura crítica de relatos de caso e avaliação de desfechos clínicos e radiográficos. Os resultados evidenciam que a fratura de instrumentos possui etiologia multifatorial, associada principalmente à fadiga cíclica, fratura por torção e fatores operacionais, sendo sua repercussão clínica dependente de variáveis como localização do fragmento, condição pulpar e presença de infecção periapical. Observa-se ausência de consenso quanto à remoção como conduta padrão, uma vez que, embora frequentemente indicada quando tecnicamente viável, pode resultar em perda significativa de estrutura dentinária e aumento do risco de fragilização radicular. Alternativas terapêuticas como o ultrapassamento do fragmento (bypass), a manutenção do instrumento em casos selecionados e intervenções cirúrgicas demonstram bons resultados quando criteriosamente indicadas. O avanço de tecnologias como microscopia operatória, ultrassom, tomografia computadorizada de feixe cônico, Endodontia guiada e sistemas digitais tem ampliado a precisão, previsibilidade e segurança dos procedimentos. Conclui-se que o manejo de instrumentos endodônticos fraturados deve ser individualizado, fundamentado em análise criteriosa de risco-benefício e em parâmetros clínicos e anatômicos, sendo que a integração entre evidência científica e recursos tecnológicos contemporâneos favorece abordagens mais conservadoras, seguras e previsíveis, com impacto positivo nos desfechos endodônticos.pt_BR

dc.description.resumo_abstractTooth fracture of endodontic instruments is a relevant clinical complication during root canal treatment, with the potential to compromise adequate disinfection of the root canal system and negatively influence the treatment prognosis. This study aimed to analyze, through a literature review, the main diagnostic and therapeutic strategies related to the management of fractured instruments, including conservative and surgical approaches as well as the impact of contemporary technologies on clinical planning. This is a literature review conducted in the PubMed and SciELO databases using the descriptor “Instrument fractures and endodontic treatment,” including studies published between 2015 and May 2026 in English and Portuguese. The analysis was based on a critical reading of case reports and evaluation of clinical and radiographic outcomes. The findings show that instrument fracture has a multifactorial etiology, mainly associated with cyclic fatigue, torsional fracture, and operational factors, with clinical impact depending on variables such as fragment location, pulpal condition, and the presence of periapical infection. There is no consensus regarding instrument removal as a standard approach, since although it is frequently indicated when technically feasible, it may result in significant dentin loss and increased risk of root weakening. Alternative strategies such as bypassing the fragment, leaving the instrument in situ in selected cases, and surgical interventions have shown favorable outcomes when properly indicated. Advances in technologies such as operative microscopy, ultrasonic tips, cone-beam computed tomography, guided endodontics, and digital systems have improved the precision, predictability, and safety of procedures. It is concluded that the management of fractured endodontic instruments should be individualized, based on careful risk–benefit assessment and clinical and anatomical parameters, with the integration of scientific evidence and modern technologies favoring more conservative, safe, and predictable approaches with positive impacts on endodontic outcomes.pt_BR
