Diffusion of Tetracycline-Impregnated Gutta-Percha Points

by Mary G. Dabuleanu, DDS, MS; Gabriel J. Faubert, BBA; John A. Molinari, PhD; Frank E. Pink, DDS, MS,

ABSTRACT The purpose of this study was to use an enzyme immunoassay to determine whether diffusion of tetracycline occurs through root dentin of extracted human teeth. Twenty-one roots were mechanically prepared and then divided into three groups: experimental (G1; n=15;

Endodontic Diagnosis for Vital Inflamed Cases: Making Clinical Decisions

by Richard Mounce, DDS

How often do we examine a patient experiencing pain and wonder if the problem is odontogenic or of another origin? Making matters more complicated, how often have we concluded that the patient’s problem is of dental origin but we are

Quick Tips For Creating Better Endodontic Results: 20 Rapid-Fire Ideas

1) Carefully study the tooth before beginning treatment. Anticipating clinical challenges and developing strategies is always far preferable to dealing with iatrogenic problems after they occur. 2) Always use a rubber dam, always. If the patient will not tolerate one,

Prevention Begins with Assessment

Recently, I was on a technical scuba diving training dive where a serious accident occurred. The situation was caused by a lack of communication and a faulty dive plan. It was completely preventable. While not potentially fatal, in an endodontic

FIGURE 6--The risk assessment algorithm extrapolates to many reconstructive protocols. Tooth #1.5 will require root canal therapy, post/core rehabilitation and full coverage regardless of whether it will be a component of a fixed bridge to replace the missing tooth or simply be reconstructed as the condition of the restoration mandates. Its use as a single functional unit in contrast to the stress impact of a bridge retainer presents a far more positive potential treatment outcome.

More Effective Endodontics Than Rotary NiTi

Regardless of what system is used to shape canals, the goal is to render a canal devoid of as much tissue as possible, producing a shape that can be obturated as close to 100% as possible. Knowing that tissue in

Endodontic Success: Two critical steps

In my opinion, the advent of predictable implant therapy is a good stimulus for endodontics. Implant therapy has, in one view, called on endodontics to improve its predictability, safety and efficiency. If endodontics has a rival in implants, endodontics must

Bacteria, Bird Droppings, and Bonded Obturation: Clinical Decisions

The conventional wisdom has traditionally been that, all things being equal, it didn’t matter what was put into root canal systems to obturate them. The old saying “What you take out is more important than what you put in” dominated
