À propos de ce livre

This book is a compilation of practical information shared by some of the finest clinical endodontists in the world. Most of the chapters are short and focus on how to perform a single clinical procedure. They are written in simple language with ample photographic support. This book provides guidance for most common endodontic procedures but also for some procedures that are less common, such as how to treat teeth containing Russian Red; surgical extrusion; root submergence; and decompression. Because most of the procedures described are performed under a dental operating microscope, there are chapters on operatory design for microscopic endodontics, microscope ergonomics for the doctor and assistant, and how to set up and use a microscope for photography and video documentation. In addition, two chapters are devoted exclusively to understanding and applying CBCT imaging. Written at a specialist level, the book serves as a desk reference for clinical procedures and as a daily practical guide, but it contains information that is useful to anyone who aspires to perform endodontics at a high level.

The Role of the Microscope in Modern Endodontic Practice
Before considering ergonomics and operatory design, we should clarify our ultimate objective. Briefly, in an ideal ergonomic practice, all procedures are performed under the microscope, even those that do not require a microscope to be performed competently. For example, screening a patient for oral cancer, administering anesthesia, and checking occlusion are procedures that are not typically thought to need magnification. The important question is not whether the microscope is required to perform a task but rather, in performing one set of tasks with the microscope and another set without it, is ergonomic efficiency negatively affected? The answer to that question is almost always “yes.”
Working in an environment where the microscope is constantly being moved into and out of the field is extremely inefficient and tends to be very distracting for the doctor, the assistant, and even the patient. Such a practice model fragments continuity of care, reduces focus on the task at hand, and often requires the use of Classes III, IV, and V motions (described later), thus dramatically decreasing both health and efficiency. For these reasons, we have come to understand that if the clinician can learn to incorporate ergonomic techniques and perform all procedures under the microscope—whether magnification is needed or not—then efficiency, focused concentration, competence, teamwork skills, and job satisfaction are all enhanced.
Understanding Basic Ergonomic Principles
Ergonomics is the science of maximizing human performance and well-being and involves a study of both human excellence and health. Proper ergonomic design is necessary to prevent repetitive strain injuries and other musculoskeletal disorders, which can develop over time and lead to long-term disability. Box 1-1 summarizes the benefits of implementing ergonomic science into operatory design.

Ergonomic classes of motion
Ergonomic science classifies the kinds of motions required to perform a specific task. Generally, a task that can be completed using a single class of motion is more efficient than the same task performed with multiple classes of motion. For example, passing a mirror using just a Class I motion is far more efficient than using a combination of Classes I, II, III, IV, and V motions. Table 1-1 summarizes the classifications of motion, and there are several videos available on YouTube demonstrating how they impact efficiency and performance during endodontic procedures.1
Table 1-1
Classifications of motion
Class I
Moving only the fingers
Class II
Movement from the wrist
Class III
Movement from the elbow
Class IV
Movement from the shoulder
Class V
Movement from the waist
In endodontics, proper ergonomic design criteria are based on the goal of reducing Classes III, IV, and V motions while producing a healthy and injury-free environment where Class I and Class II motions predominate. With proper training, discipline, and teamwork, it is possible to perform nearly all endodontic procedures under a microscope using only Class I and Class II motions, with only an occasional need for Class III motion. Once this skill is mastered, the clinician will reap the benefits of increased productivity, heightened competence, stress reduction, postural balance, and an enhanced practice culture of focused teamwork.
Executing efficient ergonomics is a habit that is mastered through repetitive training. While bad habits are difficult to break once formed, good habits and proper technique can become part of routine practice in a short period of time. A clinician or an assistant can learn the required skills if there is effortful practice and a work environment conducive to learning and mastering a new skill set.
Key design parameters of ergonomic operatory design
Operatory design and ergonomic technique go hand in hand. Even if the clinical team is practiced and wellversed in proper ergonomic skills, it is almost impossible to execute good ergonomic practice if the operatory does not reflect proper ergonomic design.
The circle of influence, a key principle in both operatory and front office design, posits that all instruments (ie, armamentaria, recordkeeping devices, viewing monitors) involved in the delivery of care should require nothing more than a Class III motion for both the doctor and the assistant (Fig 1-1). Employing such a principle places significant constraints on operatory and front office designs. Additionally, the operatory should be designed with sight angles so that there is little need to turn one’s head to view monitors, use keyboards, or procure accessory devices.

There are nine key elements that are required to realize good ergonomic operatory design (Table 1-2). The following sections describe each one briefly and discuss its role in ergonomics.
