Abstract

Introduction: The identification of root radiographic dimensions in necrotic immature permanent teeth, through mathematical models, reduces the evaluation bias.
Objective: To validate mathematical models for the identification of root radiographic dimensions in necrotic immature permanent teeth.
Method: A development research and technology evaluation was carried out, between December 2021 and May 2022, at the Stomatology Faculty of Santiago de Cuba. The initial design of the models was carried out by the work team using the brainstorming method. The validity of aspect and content was analyzed through expert consultation. Means and standard deviation were produced as a summary measure of quantitative variables. For concordance, the non-parametric Kruskal Wallis tests (in the inter-observer) and the Wilcoxon signed rank test (in the intra-observer) were obtained, with a significance level of 0.05.
Results: In the validation of the models by the experts, more than 80 % agreement was obtained. In the inter-observer and intra-observer agreement, the significance level was greater than 0.05. The average of the mathematical models I, II and III exhibit values ??less than 0.22%, 0.48 % and 0.53% respectively, which are very close to the null value.
Conclusions: The mathematical models designed are valid and reliable for the identification of radiographic root dimensions in necrotic immature permanent teeth.
