Resumen
Objetivo: Comparar Invitro los espacios formados entre dos técnicas de obturación lateral y la obturación con Gutta Flow 2 en conductos radiculares de premolares inferiores. Antecedentes: El tratamiento de conductos consiste en desinfectar el sistema de conductos radiculares para después conseguir un sellado hermético de este espacio y así prevenir la re-infección del mismo (Grossman L, 1964) En los últimos años, dentro de la gran variedad de materiales de obturación endodóntica ha surgido un material en el mercado odontológico, poco conocido como material de obturación, llamado Sistema Gutta-Flow® (Roeko Colténe/Whaledent, Langenau, Alemania), (Hammad M, , 2008;) Está compuesto de una mezcla única de gutapercha finamente molida, roeckoseal y nano plata. Esto se transforma en un material de relleno y sellador con una fácil dosificación que ofrece una excelente obturación tridimensional del conducto. Es, tixotrópico, la viscosidad disminuye cuando el material es sometido a presión, razón por la cual, el Gutta-Flow se desliza hasta en los más pequeños conductos laterales, El material se esparce levemente durante el fraguado y después sufre una ligera expansión.(Alves J, 1998;) Material y métodos: fueron instrumentados: 20 premolares; 10 para obturación lateral y 10 para obturación con Gutta Flow 2, posteriormente se diafanizaron. Se observaron y analizaron los tercios de cada muestra bajo el microscopio. Se evaluaron parámetros de espacios y longitud de trabajo. Resultados: ambas técnicas se logra apreciar pequeños espacios; de las muestras cervicales (20) en 15 (75%) de ellas se observaron poros, de las muestras del tercio medio (20) en 17 (85%) se observaron pequeños poros y finalmente el las muestras del tercio apical (20) en 08 (40%) se observaron los espacios.
To compare Invitro spaces formed between two lateral sealing techniques and sealing with gutta Flow 2 in root canals of lower premolars. Background: The root canal treatment consists of disinfecting the root canal system to achieve a tight seal after this space and prevent re-infection of the same (L Grossman, 1964) In recent years, within the wide variety of materials of endodontic filling material it has emerged in the dental market, little known as sealing material, called Gutta-Flow® System (Roeko Coltene / Whaledent, Langenau, Germany) (Hammad M, 2008;) It is composed of a unique blend of finely ground silver nano roeckoseal and gutta percha. This becomes a filler and sealer easy dosing offering excellent dimensional obturation. It is thixotropic, the viscosity decreases when the material is subjected to pressure, which is why the Gutta-Flow slides down to the smaller lateral ducts material spreads slightly during cure and then undergoes a slight expansion . (J Alves, 1998;) Material and methods were implemented: 20 premolars; Side shutter 10 for 10 for filling with Gutta Flow 2, were subsequently diafanizaron. They were observed and analyzed thirds of each sample under a microscope. Length parameters and working spaces were evaluated. Results: Both techniques can appreciate small spaces; cervical samples (20) in 15 (75%) of these pores were observed in the samples of the middle third (20) in 17 (85%) small pores were observed and finally the samples apical third (20) 08 (40%) areas were observed
