ANÁLISE DA INFLUÊNCIA DO DIÂMETRO FINAL DA INSTRUMENTAÇÃO FORAMINAL NO REPARO PERIAPICAL: ESTUDO RETROSPECTIVO

Abstract

Introduction: Periapical repair depends on the patient's clinical and systemic factors. Among the clinical factors, enlargement of the apical diameter is described as relevant to the success of the treatment. Objective: The study analyzed the influence of enlarging the final diameter of the foraminal instrumentation on the success of periapical repair of 1487 teeth clinically and radiographically diagnosed with periapical pathologies submitted to non-surgical endodontic treatment. Material and methods: Four evaluators were subjected to the Kappa test to measure the lesion at the initial consultation and after treatment, determining success in the absence of clinical manifestations and reduction of the lesion. The periapical radiographs (initial, post treatment and control) were analyzed using a tabletop light box with a digital caliper. The examiners measured the lesion considering the area with the largest radiolucent diameter. The data were tabulated in spreadsheets and exported to SPSS version 23 software, obtaining percentages, means and absolute frequencies using descriptive statistics techniques. The data were subjected to the Kolmogorov–Smirnov normality test to correlate the repair time with the final diameter of the foramen. Results: There was no statistical difference between the median file size between success and failure for the uni, V, P, MV, ML, MP canals (p>0.05). However, there was a statistical difference in success rates in distal canals, when the median file size was #45 compared to #35. Conclusion: It can be inferred that increasing the diameter of the canal can influence the repair and that new assessments associated with other variables should be studied
