Objetivo Comparar in vitro, mediante el uso de microscopio electrónico de barrido la penetración de 3 selladores endodónticos: A base de resina epóxica AH Plus®, a base de polidimetilsiloxano Roekoseal® y a base de Hidróxido de Calcio, Apexit Plus® en los túbulos dentinarios a 3 y 7mm del ápice radicular con la técnica de compactación lateral en piezas premolares inferiores unirradiculares. Materiales y Métodos: Se prepararon 36 piezas dentarias, se dividieron en tres grupos de 12 piezas cada grupo y se obturó con 3 selladores diferentes, las piezas fueron cortadas transversalmente a 3 y 7mm del ápice radicular y luego preparados para ser observadas en el microscópico electrónico de barrido, se evaluaron la penetración de los selladores en los túbulos dentinarios. Resultados: Se utilizó la prueba de Anova para comparar los tres grupos y la Prueba de T de Student para ...

Objective: To compare in vitro, through the use of a scanning electron microscope, the penetration of three endodontics sealers: Based on epoxy resin AH Plus®, based on polydimethylsiloxane Roekoseal® and based on Calcium Hydroxide, Apexit Plus® in the dentinal tubules 3 and 7mm from the root apex with the lateral compaction technique in single-root inferior premolar pieces. Materials and Methods: In vitro study, 36 teeth were prepared and divided into three groups of 12 pieces each group. All the pieces were prepared and each group was filled with three different endodontic sealers. Subsequently, the pieces were cut transversely at 3 and 7 mm from the root apex; They were then prepared to be taken to the scanning electron microscope to observe the penetration of the sealers into the dentinal tubules. Results: The Anova test was used to compare the three groups and the Student's ...

Dens invaginatus (DI) is a dental alteration that occurs before mineralization and is a consequence of the folding of the enamel organ within the dental papilla. Its characteristics allow the onset and rapid progression of carious lesions and, consequently, pulp and periapical disease.  This article summarizes data from original articles and literature reviews from the Scopus/PubMed database. Therefore, the aim of the present literature review is to expose guidelines for the clinical management of Dens invaginatus according to its etiology, classification and diagnosis, thus representing an improvement in the effectiveness of the treatment and prognosis of these very complex alterations.
