Prognostic Factors in Endodontic Surgery Using an Endoscope: A 1 Year Retrospective Cohort Study

Abstract

This retrospective study clarified the success rate of endoscopic endodontic surgeries and identified predictors accounting for successful surgeries. In this retrospective study, 242 patients (90 males, 152 females) who underwent endoscopic endodontic surgery at a single general hospital and were diagnosed through follow-up one year later were included. Risk factors were categorized into attributes, general health, anatomy, and surgery. Then, the correlation coefficient was calculated for the success or failure of endodontic surgery for each variable, the odds ratio was calculated for the upper variable, and factors related to the surgical prognosis factor were identified. The success rate of endodontic surgery was 95.3%, showing that it was a highly predictable treatment. The top three correlation coefficients were post, age, and perilesional sclerotic signs. Among them, the presence of posts was the highest, compared with the odds ratio, which was 9.592. This retrospective study revealed the success rate and risk factors accounting for endoscopic endodontic surgeries. Among the selected clinical variables, the presence of posts was the most decisive risk factor determining the success of endodontic surgeries.

Incidence and Risk of Anti-Resorptive Agent-Related Osteonecrosis of the Jaw after Tooth Extraction: A Retrospective Study

“…Therefore, it is necessary to identify risk factors using odds ratios by multivariate analysis. The advantage of calculating the correlation coefficient is that one can quickly and visually evaluate the correlation between two factors [ 19 ]. Our study is novel in that it is the first to identify risk factors for tooth extraction-induced ARONJ using correlation coefficients.…”

A obturação retrógrada no tratamento de lesão periapical persistente – revisão de literatura

“…A cirurgia parendodôntica apresenta uma alta taxa de sucesso de 95,3%, a contribuição para o resultado está no emprego do microscópio operatório, facilitando a visão do campo operatório, além de técnicas modernas, utilização do ultrassom com pontas Brazilian Journal of Health Review, Curitiba, v. 6, n. 1, p. 872-885, jan./feb., 2023 anguladas, instrumentos microcirúrgicos e novos materiais retrobturadores. (PALLARÉS-SERRANO et al, 2021;SUKEGAWA et al, 2022) A avaliação pré-operatória é uma das etapas fundamentais para um correto planejamento cirúrgico e ela engloba histórico médico e odontológico, exames intra-orais e extra-orais e exames complementares incluindo principalmente o uso de exames de imagens como radiografias tridimensionais (3-D) como a TCFC para um correto diagnóstico e para avaliação das estruturas anatômicas como: espessura óssea, tamanho da lesão e a correta posição de raízes como a disto lingual. A proximidade do elemento com o seio maxilar não invalida a cirurgia, porém, é necessário cautela para que não ocorra comunicação ou a entrada de resíduos infectados para dentro desse seio, na mandíbula também é necessário ter cuidado devido a presença do forame mentual e do nervo alveolar inferior (CHONG e RHODES, 2014;WANG et al, 2017) Na cirurgia endodôntica moderna a osteotomia pode variar de 4-5 mm, tamanho suficiente para fornecer espaço para a ponta ultrassônica de 3 mm, tendo que levar em conta também que na maior parte dos casos de cirurgia paredodôntica se tem a presença de uma lesão e consequentemente uma destruição da cortical óssea na região apical, o que facilita a localização e determina se será necessário ou não a realização da osteotomia que fica de acordo com essa destruição ao redor do ápice (KIM e KIM, 2019).…”

Critical Factors Affecting Outcomes of Endodontic Microsurgery: A Retrospective Japanese Study

“…In addition, if an isthmus is present on the surgically prepared surface of the root, isthmus preparation may be performed, but the effect of this preparation on post-treatment success is not defined [14,15]. While the therapeutic value of EMS is recognized in Japan [15,16], no studies have quantified outcomes and the relative importance of the pre-treatment factors described above. Here we conducted a retrospective analysis with one year follow-up of the preoperative and intraoperative factors that affect the success of EMS in Japanese patients.…”
