Precisión de los localizadores apicales electrónicos AI-Pex, Findpex y Root ZX II en la determinación de la longitud de trabajo en dientes humanos: estudio in vitro
Resumen
Introducción: Los localizadores electrónicos de ápice (LEA) han probado ser precisos y eficaces para localizar la constricción apical, el límite de la instrumentación y la obturación del SCR en comparación con la radiografía periapical convencional. Aunque estos dispositivos pueden minimizar el error de la medición y proporcionar mejores resultados clínicos, es necesario evaluar la precisión de los nuevos modelos para garantizar el éxito del tratamiento endodóntico. Objetivo: comparar in vivo la precisión de dos localizadores apicales electrónicos Ai-PEX, FindPex y el gold estándar Root ZX II. Materiales y métodos: La muestra incluyó 35 unidades dentarias monorradiculares extraídos de humanos. Las medidas obtenidas por LEA fueron estudiadas mediante la realización de un análisis estadístico inferencial donde se compararon los datos del instrumento de recolección de datos por medio de la prueba ANOVA de un factor para la precisión de cada LEA con el software estadístico IBM SPSS versión 25. Resultados: El Root ZX II presentó la mayor precisión, seguido por Ai-Pex y FindPeX. Se encontraron diferencias significativas entre los LEA y el método radiográfico (p < 0,0501), pero no entre los tres LEA (p > 0,05). Conclusiones: Todos los LEA estudiados son dispositivos seguros, confiables y clínicamente predecibles para el tratamiento endodóntico.
