The K3 Rotary Nickel Titanium File — Predictable Root Canal Instrumentation

by Rich Mounce, DDS

Having used all the rotary nickel titanium (RNT) systems available in North America, I have come to rely upon the K3 RNT system (SybronEndo, Orange, CA) as my preferred file. K3 stands in distinction to the other RNT root canal

Prevention Begins with Assessment

by Richard Mounce, DDS

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.

The functional success rates for endodontically treated teeth are without equal.1 As it is manifest that a natural tooth is preferable to an unnatural replacement, it is therefore incumbent on the practitioner to be familiar with what is possible in

More Effective Endodontics Than Rotary NiTi

by Barry L. Musikant and Allan S. Deutsch

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

How Many Times Can I Use a Rotary Nickel Titanium File?

by Rich Mounce, DDS

Recently I was asked this question by a reader. The answer is primarily dependent on the brand of rotary nickel titanium (RNT) file used, taper, tip size, how many times it has been used previously and under what conditions. Obviously,

Endodontic Success: Two critical steps

by Rich Mounce, DDS

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

FIGURE 1--The value with regard to the benefits of bonded obturation cannot be overstated and include for the first time, an obturation that to the greatest extent possible in Endodontics ever, fulfils the three principle functions of a root canal filling listed above. In the empirical opinion of the author, there is no credible evidence in the endodontic literature that RealSeal is not the advance claimed.

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

Is It Essential To Pre-curve K Files Before Use?

In a word, yes! K files are indeed essential to pre-curve prior to use. First off, canal systems are never straight, no matter how the radiograph may appear. No line in nature is straight and canals contain a dimension of
