A Endodontia tem evoluído significativamente com a incorporação de tecnologias de ampliação, destacando-se o Microscópio Operatório (MO) como um instrumento fundamental na melhoria dos resultados clínicos. Este trabalho tem como objetivo avaliar o impacto do recurso ao MO na taxa de sucesso do tratamento endodôntico cirúrgico e não cirúrgico, analisando as suas vantagens, limitações e a forma como contribui para uma prática clínica mais precisa. Foi realizada uma revisão da literatura científica atual, com base em estudos clínicos, revisões sistemáticas. Como critérios de inclusão utilizamos: Estudos clínicos comparativos e revisões sistemáticas cujo objetivo de estudo é uso de MO ou outros dispositivos de ampliação nos tratamentos endodônticos. Estudos publicados nos últimos 20 anos em inglês, português e espanhol. Critérios de exclusão: Estudos em animais, estudos laboratoriais in vitro, artigos de opinião, cartas ao editor e resumos de conferências sem texto completo. Serão incluídos estudos comparativos clínicos, revisões sistemáticas, meta-análises e ensaios controlados randomizados, que comparem diretamente o uso de MO com tratamentos endodônticos convencionais sem microscopia. Iremos analisar trabalhos publicados no intervalo temporal 2004 e 2025. A seleção dos estudos seguirá o protocolo PRISMA. Os títulos e resumos serão inicialmente avaliados, seguindo-se a leitura completa dos artigos selecionados. Os dados serão recolhidos utilizando uma tabela padronizada, incluindo variáveis como número de pacientes, entre outros. A avaliação da qualidade dos estudos será feita através da ferramenta Cochrane para ensaios clínicos e o risco de viés será avaliado pela escala ROBINS-I para estudos não randomizados. Revisões sistemáticas serão avaliadas pela ferramenta AMSTAR 2. Os dados sugerem que a utilização do MO permite uma melhor visualização de detalhes anatómicos, deteção de canais acessórios, fraturas e outras alterações que, de outra forma, poderiam passar despercebidas, contribuindo para o aumento da taxa de sucesso do tratamento endodôntico. Apesar das suas vantagens, o uso deste equipamento requer formação adequada e implica desafios logísticos e económicos. Conclui-se que o MO representa um avanço significativo na endodontia contemporânea, sendo um aliado na obtenção de tratamentos mais previsíveis e eficazes.
Endodontics has significantly evolved with the incorporation of magnification technologies, with the Operating Microscope (OM) standing out as a key instrument in improving clinical outcomes. This study aims to evaluate the impact of using the OM on the success rate of both surgical and non-surgical endodontic treatment, analyzing its advantages, limitations, and how it contributes to more precise clinical practice. A review of the current scientific literature was conducted, based on clinical studies and systematic reviews. Inclusion criteria: Comparative clinical studies and systematic reviews focused on the use of OM or other magnification devices in endodontic treatments. Only studies published in the last 20 years in English, Portuguese or Spanish were considered. Exclusion criteria: Animal studies, in vitro laboratory studies, opinion articles, letters to the editor, and conference abstracts without full text. The review will include comparative clinical studies, systematic reviews, meta-analyses, and randomized controlled trials that directly compare the use of the OM with conventional endodontic treatments without microscopy. Publications from the period between 2004 and 2025 will be analyzed. Study selection will follow the PRISMA protocol. Titles and abstracts will be initially screened, followed by full-text reading of selected articles. Data will be collected using a standardized table, including variables such as the number of patients, among others. The quality of the studies will be assessed using the Cochrane tool for clinical trials and the risk of bias in non-randomized studies will be evaluated with the ROBINS-I scale. Systematic reviews will be assessed with the AMSTAR 2 tool. The evidence suggests that the use of the OM enables better visualization of anatomical details, detection of accessory canals, fractures and other conditions that might otherwise go unnoticed, thus contributing to higher success rates in endodontic treatment. Despite its advantages, the use of this equipment requires proper training and involves logistical and economic challenges. It is concluded that the OM represents a significant advancement in contemporary endodontics, serving as an ally in achieving more predictable and effective treatment.
