Factors associated with survival of teeth following initial endodontic therapy
… is to review the tooth retention rate of primary endodontically treated teeth at University of Pennsylvania Graduate Endodontics department (PGE) and faculty practice (PDFP) and compare it to the tooth retention rate of non-surgical retreatment and surgical retreatment and test the hypothesis-- …

Influence of an Irrigation System Utilizing Apical Negative Pressure on Bacterial Elimination during Endodontic Therapy: a prospective randomized clinical study
<p>The rationale of endodontic therapy is obtaining a microbe-free root canal system, in which irrigation plays a critical role. Previous investigations of irrigants and the efficacy of delivery systems have yielded mixed results in obtaining microbe-free (MF) root canals. Recent in-vitro studies …

The Effect of Hypertension on Periapical Disease: a Retrospective Study Utilizing Machine Learning to Assess a Dental School Population
… history data of patients who required primary endodontic therapy was collected, and periapical disease was defined as having symptomatic apical periodontitis, asymptomatic apical periodontitis, chronic apical abscess, or acute apical abscess. We identified large imbalances within the data, and …

Healing Processes of Periapical Endodontic Leasions after Retrograde Filling // Оздравителни процеси на периапикални възпалителни изменения от ендодонтски произход след ретроградно запълване
Endodontic surgery is an important part in the treatment of endodontic lesions. Sometimes it is the only option for some endodontic conditions. The apical resection ends with an exposed apical dentine surface which is why it is sometimes necessary to perform a retrograde cavity for a retrograde …

The prevalence of second canals in the mesiobuccal root of maxillary molars in a South African subpopulation : a cone beam computed tomography study
Introduction: Endodontic therapy is a global routine dental therapeutic procedure. Despite recent and present advances in dentistry and particularly with the popularity of implant dentistry, it remains biologically and aesthetically advantageous for retention of one�s original dentition. Tooth …

Contemporary methods of treatment of injuries and their complications in immature permanent teeth in children
This study deals with the evaluation of endodontic treatment using calcium hydroxide materials in immature permanent teeth that have sustained traumas, especially after severe periodontal tissue injuries. - The aim of this work was: a. to analyze the factors that contribute to occurrence of …

The Use of Implants vs. Endodontics: Practitioner Attitudes in 2007
… deciding whether to place an implant or perform endodontic retreatment. Null hypothesis: Dentists today are no more likely to place an implant than to perform endodontic retreatment. A twelve-item questionnaire was mailed to 525 general dentists and specialists who are members of the Richmond …

Comparison of an Ultrasonic and a Non-Ultrasonic Endodontic Irrigation Protocol: A Clinical Study
… with a posterior tooth requiring primary endodontic treatment of a necrotic pulp, diagnosed by negative cold test and periapical radiolucency. Standard non-surgical endodontic therapy was performed on both groups using micro-tip irrigation syringes. After completion of instrumentation, …

Effect of Antibiotic Pastes on Chemical Structure and Microhardness of Radicular Dentin
Introduction: Regenerative endodontic therapy in immature teeth with necrotic pulps triggers continued root development, thereby improving the prognosis of these teeth. Disinfection of the canal is accomplished with an intracanal medicament, such as triple antibiotic paste (TAP) composed of …

An in-vitro comparison of working length determination between a digital system and conventional film when source-film/sensor distance and exposure time are modified
Accurate determination of working length during endodontic therapy is a crucial step in achieving a predictable outcome. This is determined by the use of electronic apex locators, tactile perception, and knowledge of average tooth lengths and/or dental radiography whether digital or conventional is …

Συγκριτική in vivo μελέτη της δράσης των διαλυμάτων χλωρεξιδίνης και χλωρεξιδίνης-κετριμίδης στη βακτηριακή χλωρίδα απολφών δοντιών
… 1% solution was used. Using standard antiseptic endodontic technique, access to the root canal was achieved and an initial culture from the canal was obtained by means of sterile paper points. In the first appointment the canal was then biomechanically cleaned by using as irrigation solution one …

Analysis of Periapical Biopsies Submitted for Histopathological Evaluation: A Retrospective Study
… the course of assessing a tooth for non-surgical endodontic therapy, careful clinical evaluation aids in diagnosing a large majority of odontogenic inflammatory lesions. However, lesions unrelated to apical periodontitis also occur in the periapical region. Histopathologic examination of …

An in vitro comparison of working length accuracy between a digital system and conventional film when vertical angulation of the object is variable
Accurate determination of working length during endodontic therapy is critical in achieving a predictable and successful outcome. Working length is determined by the use of electronic apex locators, tactile perception, knowledge of average tooth lengths and dental radiography. Due to the increasing …

An in-vitro SEM study comparing the debridement efficacy of the EndoVac® system versus the Canal CleanMax® following hand-rotary istrumentation
This in-vitro, prospective, randomized study microscopically compared the debridement efficacy of negative pressure irrigation with the EndoVac (Discus Dental, Culver City, CA) versus the Canal CleanMax (Maximum Dental, Inc., Secaucus, NJ). Sixty extracted human canines were instrumented using a …
