Applications of cone beam computed tomography in endodontics Evid.-Based Endod. Pub Date : 2020-09-21 Ateksha Bhardwaj Khanna
Endodontic disease can adversely affect the quality of life and therefore early diagnosis and consequent timely treatment is of paramount importance for the Endodontist. Radiology is an essential component in treatment planning, disease monitoring and assessment of treatment outcome. Periapical radiographs and panoramic radiography are frequently utilised but they provide only two-dimensional representation

Pub Date : 2019-12-11 Randall Mikulik, Ali Naji, Ransome van der Hoeven, Igor Tsesis, Eyal Rosen, David E. Jaramillo
Increase in efficacy during root canal irrigation may contribute to better treatment outcomes. This study investigated the efficacy of ultrasonic and negative pressure irrigation systems using sodium hypochlorite (NaOCl) in the reduction of bacterial load in human teeth. One hundred thirty-one single-rooted teeth were cleaned and shaped, autoclaved, and incubated with E. faecalis. Teeth were randomly

Antibiofilm activity of epoxy sealer incorporated with quaternary ammonium macromolecule Evid.-Based Endod. Pub Date : 2019-02-26 Tal Becker, Nir Sterer, Ronit Bar-Ness Greenstein, Tamar Toledano, Michael Solomonov
A common reason for failure of root canal treatment is residual bacterial biofilm or reinfection due to coronal seal inadequacy. Recently, the idea of using macromolecules with antibacterial features has evolved. The addition of nanoparticle macromolecules to sealers gained antibiofilm properties as shown in several in vitro studies. Nevertheless, no technique has yet been able to completely eliminate

The preservation of teeth with root-originated fractures Evid.-Based Endod. Pub Date : 2018-03-16 Eyal Rosen, Ilan Beitlitum, Igor Tsesis
Traditionally, when a root-originated fracture (ROF) was diagnosed in an endodontically treated tooth, the tooth was scheduled for extraction. However, modern endodontics offers new treatment options to manage and maintain certain ROF teeth. The decision of whether to extract a ROF tooth and substitute it with a dental implant, or to implement a more conservative management approach by attempting an

Root-originating dentinal defects: methodological aspects and clinical relevance Evid.-Based Endod. Pub Date : 2017-12-21 Peter Zahi Tawil, Elisa Kristin Arnarsdottir, Marcelo Santos Coelho
It was in the 1980s when the association between root-filling procedures and dentinal microcracks was made. Nowadays, root-originating microcracks, also known as dentinal defects, are recognized as a possible precursor that is part of the longitudinal process of root-originating fractures. The presence of dentinal defects has been shown to significantly decrease the outcome through a periapical microsurgery

Implant-associated cracked teeth: case series Evid.-Based Endod. Pub Date : 2017-08-22 Eyal Rosen, Tomer Goldberger, Aviad Tamse, Carlos E. Nemcovsky, Salmon Breslauer, Ilan Beitlitum, Igor Tsesis
This study presents a series of 18 cases of cracked non-endodontically treated teeth that were diagnosed following the placement of adjacent implant-supported rehabilitation. These findings could suggest a possible cause/related events. Most of the cases occurred in female patients (61%), over 50 years old (78%, with an average age of 59 years). Nine (50%) of the cracked teeth were molars, 7 (39%)

Smear layer and debris removal from dentinal tubules using different irrigation protocols: scanning electron microscopic evaluation, an in vitro study Evid.-Based Endod. Pub Date : 2017-07-17 Hsin-Hui Wang, Daniel Sanabria-Liviac, Philippe Sleiman, Samuel O. Dorn, David E. Jaramillo
This study investigated the ability of different irrigation protocols to keep dentinal tubules (DT) open and avoid their blockage by the smear layer (SL) during the cleaning and shaping procedure (CSP). Twenty-five extracted teeth were divided into five groups (n = 5): group 1, NaOCl was kept in the canal during instrumentation and then washed out with distilled water, and the canal was irrigated with

Biological complications in implant-supported oral rehabilitation: as the pendulum swings back towards endodontics and tooth preservation Evid.-Based Endod. Pub Date : 2017-06-24 Carlos E. Nemcovsky, Eyal Rosen
The decision whether to retain a tooth by additional endodontic and restorative treatments or to extract it and replace it with an implant-supported restoration has been extensively debated, and the common approach to this clinical question has shifted back and forth many times. However, in recent years, it has become clear that implants are more prone to technical and biological complications, and

What do we (do not) know about the use of cone beam computed tomography in endodontics? A thematic series with a call for scientific evidence Evid.-Based Endod. Pub Date : 2017-06-06 Kıvanç Kamburoğlu, Igor Tsesis, Eyal Rosen
Cone beam computed tomography (CBCT) has become a common diagnostic method in endodontics. However, the current literature provides insufficient information about different aspects that are related to the use of CBCT, such as: the efficacy of CBCT to support the practitioner’s clinical decision making and to affect treatment outcomes; about the required training of the practitioner so he can efficiently

Speculations, knowledge, and evidence about crown and root fractures Evid.-Based Endod. Pub Date : 2017-05-31 Eyal Rosen, Igor Tsesis, Aviad Tamse
Crown and root originating fractures are the main fractures occurring in teeth. Crown origination fracture (COF) usually occur in premolars and molars, in non-endodontically treated teeth (vital and non-vital) with symptoms related to the diseased pulp, while root-originating fractures (ROF) occur in root canal-treated teeth with or without coronal restoration and symptoms related to chronic or acute

Classifying scientific evidence as the basis for evidence-based decision making: is strength of evidence absolute? Evid.-Based Endod. Pub Date : 2016-08-03 Eyal Rosen, Igor Tsesis
One of the most challenging aspects of evidence-based decision making is the appraisal of the available evidence in order to separate the wheat from the chaff. It has been stated that “not all evidence is created equal” (Cochrane Consumer Network - Levels of evidence), and it has been recommended to grade the available literature by the strength of evidence as determined by the methods used to minimize

Apical termination of root canal procedures—ambiguity or disambiguation? Evid.-Based Endod. Pub Date : 2016-07-22 James L. Gutmann
The issues of working length determination, its apical extent, and the position of the final root canal filling have been controversial, as differing points of view have existed between the biologically based and clinically based endodontic gurus regarding this concept for decades. Coupled with the following issues, it has become somewhat of an empirical bastion for clinicians, especially those in

From pulpal stem cells to tooth repair: an emerging field for dental tissue engineering Evid.-Based Endod. Pub Date : 2016-05-03 Anne Baudry, Emel Uzunoglu, Benoit Schneider, Odile Kellermann, Michel Goldberg
In current dental practices, traditional restorative approaches may have relatively limited long-term survival and may be associated to diverse complications, such as allergy, pulpitis, or periodontal pathologies. To overcome these shortcomings, novel innovative strategies have been envisioned for tooth repair. During the two last decades, the extensive advances in our understanding of tooth development

Developments in the quantity and quality of endodontic publications: two sides of the same coin? Evid.-Based Endod. Pub Date : 2016-05-03 Eyal Rosen, Igor Tsesis
Since the beginning of modern mankind, scientists have been trying to comprehend the forces of nature. This quest for knowledge has evolved during history, as the methods to assess and analyze the data became more and more structured and controlled. In 1924, Alfred E. Cohn stated: “since the renaissance, men of science have indeed been continuously eager to escape from those influences which tended

Reactionary and reparative dentin formation after pulp capping: Hydrogel vs. Dycal Evid.-Based Endod. Pub Date : 2016-05-03 A Njeh, E Uzunoğlu, H Ardila-Osorio, S Simon, A Berdal, O Kellermann, M Goldberg
After indirect capping, injured odontoblasts generate reactionary dentin, whereas after direct capping of a pulp exposure pulp, cells stimulate the formation of reparative dentin. The aim of this study was to evaluate and compare the effects of two direct capping agents on pulp tissue reactions: Hydrogel (a bovine serum albumin (BSA)/glutaraldehyde,) and Dycal (a calcium hydroxide-based capping agent)
