Article
Background/aim: The high rate of root resorption resulting from tooth replantation represents a serious clinical problem. In order to prevent ankylosis and replacement resorption, the contemporary literature highlights the importance of using a flexible stabilization for traumatized teeth. For this purpose, orthodontic devices may be promising for...

Objectives To evaluate via scanning electron microscopy the amount of smear layer generated during the use of sonic and ultrasonic activation systems with standardized short-term intentional contacts with the canal walls.MethodologySeventy single-root human teeth were randomly assigned to 2 control (n = 5 each): NC (negative control), PC (positive...

Background/Aim The extra‐alveolar dry period and storage medium in which a tooth is kept prior to replantation remain critical factors affecting the survival and repair potential of the periodontal ligament in avulsed teeth. When replantation is not immediate, replacement root resorption (RRR) is the most common complication. The aim of this histol...
Article
Objective: The purpose of this study was to determine the efficacy of different irrigants and irrigation protocols in the removal of gutta-percha and sealer from simulated un-instrumented areas. Methods: Eighty-four uniradicular teeth were used. After standardizing working length (WL) and preparing the glide path, coronal flaring was performed....

Background The aim of this study was to evaluate the effectiveness in dentin debris and smear layer removal from root canal walls using EDTA and QMix® alone and also activated with Nd:YAG laser. Material and Methods 50 single-rooted teeth were instrumented and divided in 5 groups according to irrigation protocol: 17% EDTA, QMix®, Nd:YAG laser alon...
Article
Background The purpose of this study was to determine whether differences exist in disinfection protocols between endodontists and general dentists. Methods The authors sent an invitation to participate in a Web-based survey to 950 dentists affiliated with the Spanish Board of Dentistry. Participants responded to 9 questions about irrigation pro...
Chapter
Positive pressure (PP) delivery system represents the most used method for irrigation during root canal treatment. PP irrigation consists of syringes and needles inserted into the canal while pressure is applied to distribute the irrigant solution to the entire canal system. This chapter discusses the factors affecting efficacy of positive pressure...
Chapter
There are numerous irrigation solutions and irrigation techniques available and many of them have showed improvement even in the complex canal systems. This chapter focuses on the apical negative pressure (ANP) irrigation system's unique abilities, advantages, and benefits. EndoVac was the first ANP system available commercially. The EndoVac's effe...

Algunas de las dificultades que nos encontramos en los retratamientos son la eliminación del material de obturación intraconducto y la presencia de dentina muy contaminada por microorganismos resistentes, en muchas ocasiones asociados en biofilms. En el caso que presentamos nos ayudamos en la última fase del retratamiento de un nuevo sistema que co...
Article
The purpose of this investigation was to determine the effect that apical preparation size and preparation taper have on the volume of irrigant delivered at the working length for different canal curvatures using apical negative pressure irrigation. One hundred fifty-five human teeth (55 maxillary canines and 100 mandibular molars) were used in thi...

Article
Aim: To evaluate the penetration of irrigants up to working length using two different activation systems in curved canals instrumented with 0.04 and 0.08 taper instruments. Methodology: Sixty-eight mesiobuccal canals from mandibular first molars with curvatures between 30° and 40° were used. The samples were divided into group 1, canals instrum...
Article
The shaping ability of root canal instruments is determined by a complex interrelationship of parameters such as cross-sectional design and the ability to remove debris and the smear layer. The self-adjusting file (SAF) consists of a hollow, flexible instrument in the form of a compressible, thin-walled, pointed cylinder. The aim of this study was...

To assess the ability of sodium hypochlorite (NaOCl) to penetrate simulated lateral canals and to reach working length (WL) when using the self-adjusting file (SAF). Seventy single-rooted teeth with oval-shaped canals were used. Upon access, presence of a single canal was confirmed by direct visualization under a dental-operating microscope. Canal...

RESUMEN El objetivo de esta revisión bibliográfica sobre los principales artículos publicados en revistas de impacto dentro del campo de la endodoncia es analizar, a las vista de los resultados que encontramos en la literatura la penetración real de nuestros irrigantes dentro de sistemas de conductos. Muchos son los estudios in vitro que obtienen b...
Article
Invasive cervical resorption (ICR) is a type of external resorption that begins below the epithelial attachment. The etiology of ICR is mainly caused by trauma or orthodontic treatment. In many cases, cone-beam computed tomography (CBCT) is a very useful tool to achieve proper diagnosis. This case presented with invasive cervical resorption class I...
Article
The removal of vital and necrotic pulp tissue, microorganisms, and their toxins is essential for endodontic success. However, the complex anatomy of the root canal system has limited our ability to debride it completely. Hence the purpose of this study was to evaluate the effect of currently used irrigation and activation systems on the penetration...
Article
The purpose of this study was to evaluate the penetration of 5.25% sodium hypochlorite alone or in combination with 17% EDTA in simulated lateral canals using sonic and ultrasonic activation. Four hundred and eighty simulated lateral canals were created in 80 single rooted cleared teeth by inserting 06 K-files at 2, 4.5 and 6 mm of working length....

Question
I consider MTA a predictable method to obtain a sealing in those situations but Revascularization has showed compromising results. Is this technique enough supported in the literature to considered to be the treatment of choice?
