Bacterial Removal Promoted by 2 Single-file Systems: Wave One and One Shape

By Dr. Barry H. Korzen | Posted August 28, 2014

With many practitioners moving to single-file systems due to their ease of use and savings in time it is important to ensure that this new technology effectively removes bacterial content from the root canal.

A Panoramic Survey of Air Force Basic Trainees: How Research Translates into Clinical Practice

By Dr. Barry H. Korzen | Posted July 27, 2014

A young adult population, like those evaluated in this study, should have the best chance of receiving ideal endodontic treatment. This paper evaluated 35,811 panoramic radiographs of United States Air Force inductees and the correlation between best practices and actual treatment rendered is disheartening.

Effect of Ibuprofen on Masking Endodontic Diagnosis

By Dr. Barry H. Korzen | Posted July 9, 2014

Prior to undertaking any procedure the clinician must formulate a treatment plan based on an accurate assessment of the patient’s chief complaint. However, 64%–83% of patients with dental pain take analgesics before seeing a dentist. Read et al undertook a study “to examine the possible “masking” effect of ibuprofen on endodontic diagnostic tests.”

Effectiveness of different intracanal irrigation techniques in removing intracanal paste medicaments

By Dr. Barry H. Korzen | Posted May 26, 2014

In non-surgical multi-visit endodontic procedures the placement of medication for bacterial control and/or pain relief is a common treatment approach. But prior to obturation this medication must be removed so as not to interfere with the placement of the final obturation of the canal. Various irrigation techniques and different medications were studied. The authors found that the position of the irrigational needle and the type of medicament used are key factors which influence the effectiveness of irrigation in removing medicaments.

Shrinkage of Backfill Gutta-percha upon Cooling

By Dr. Barry H. Korzen | Posted April 27, 2014

One goal of non-surgical endodontics is sealing the root canal space hermetically and gutta-percha is still the main filling material of choice. In a paper published in the May 2014 issue of the Journal of Endodontics Lottanti, Tauböck and Zehnder investigated the “shrinkage of gutta-percha used for the backfilling procedure under clinically relevant conditions.”

Role of Ultrasonography in Differentiating Facial Swellings of Odontogenic Origin

By Dr. Barry H. Korzen | Posted April 23, 2014

A study published in the April 2014 Journal of Endodontics undertook to determine “if ultrasound were more accurate than a blind incision for drainage procedure in locating purulence…”. The study compared clinical examination plus ultrasonography versus clinical examination alone in differentiating cellulitis from abscesses in patients with facial swelling of odontogenic origin.

Influence of Operator’s Experience on Root Canal Shaping Ability with a Rotary Nickel-Titanium Single-File Reciprocating Motion System

By Dr. Barry H. Korzen | Posted March 27, 2014

All too frequently we are told by manufacturers’ representatives that the product or technique they are demonstrating is so simple that a transition to this new technique will be quick and easy. Muñoz et al. evaluated the influence of operator’s experience on the shaping of double-curvature simulated root canals. Their results indicated “the importance of previous training and the need to acquire experience, in spite of the system’s apparent simplicity.”
