Autotrasplante dental. Una opción terapéutica contrastada / No disponible

El autotrasplante dental es una técnica clínica clásica que desde su protocolización por la escuela escandinava en los años 50 del pasado siglo permite obtener de forma predecible excelentes resultados. Si bien la introducción de los implantes dentales llevó a un cierto ostracismo a los autotrasplantes, progresivamente se ha ido reincorporando al armamentario clínico habitual como excelente método para reponer dientes ausentes. El índice de fracasos es bajo cundo se sigue un protocolo clínico estricto, que en los últimos tiempos incorpora el uso de réplicas 3D para minimizar el tiempo extraoral del diente donante. El momento ideal para realizar un autotrasplante se da cuando el diente donante tiene formado entre 2/3 y ¾ de la raíz, lo que permite que esta complete su desarrollo y mantenga la vitalidad pulpar. No obstante, es también posible realizar autotrasplantes de dientes con ápice cerrado, si bien en estos casos es imperativo realizar el tratamiento de conductos. El comportamiento de un diente autotrasplantado es idéntico al de cualquier otro diente, permite el crecimiento del hueso, e incluso movimientos ortodóncicos. En caso de pérdida de dientes en sector estético en pacientes jóvenes el autotrasplante es la opción de elección siempre que sea posible disponer de un diente donante

Influence of academic training in endodontics and implantology on decision-making in undergraduate students.

PURPOSE: To evaluate the effect of academic training on decision-making in a group of undergraduates who have undergone training in endodontics and implantology. BASIC PROCEDURES: A single group of undergraduate dentistry students (n = 65) was given a survey consisting of 15 endodontic cases. Each case included periapical radiographs and clinical photographs. Students were asked to select one of the eight proposed treatments. In their 4th year, the students first responded to the survey after completing endodontics. One year later, after completing their studies in implantology, the same students completed the same survey again. MAIN FINDINGS: Under the conditions of this study, differences in undergraduate training significantly affected treatment decisions. PRINCIPAL CONCLUSIONS: Undergraduate decision-making was affected by academic training.

Evaluation of Dentaport ZX and Raypex 6 electronic apex locators: An in vivo study

INTRODUCTION: Raypex 6 is an electronic apex locator (EAL) that has not yet been tested in vivo. The purpose of this in vivo study was to compare the accuracy of two EALs: the Dentaport ZX and the Raypex 6. METHODS: The study involved 36 straight single-rooted teeth. A 10-K file was advanced until the EAL detected the major foramen. The file was fixed in a replaceable pattern of light-cured composite. The apical part of each canal was trimmed to expose the file tip. The distances from the file tips to the major foramen were measured. RESULTS: Wilcoxon's signed Rank test found no significant differences between the Dentaport ZX and Raypex 6 in terms of their abilities to detect the major foramen (P = .52) The Dentaport ZX was accurate 82.35% of the time to ± 0.5 mm and 97.05% of the time to ± 1 mm, whereas the Raypex 6 was accurate 88.22% of the time to ± 0.5 mm and 100% of the time to ± 1 mm. CONCLUSIONS: No statistically significant differences were observed between the performance of the Dentaport ZX and Raypex 6 EALs under the in vivo clinical conditions used in this study
