WHY THIS MASTERCLASS MATTERS

See More. Remove Less. Access Smarter.

The SAC — Smart Access Cavity is a modern approach to endodontic access cavity preparation based on one simple principle:

Remove only what is necessary to see, reach, instrument and disinfect the root canal system — while preserving as much sound tooth structure as possible.

Conservative does not simply mean smaller. A truly conservative access requires a clear understanding of the internal anatomy, careful preoperative analysis, magnification, controlled dentin removal and, above all, the right instruments for the right clinical situation. In this exclusive masterclass, Dr. Claudio Farnararo will present the principles and clinical workflow behind the SAC.

The Right Bur. The Right Move. The Right Reason.

One of the key elements of the SAC concept is the rational selection of specific burs for each stage of access preparation. During the masterclass, Dr. Farnararo will introduce a dedicated sequence of Microcopy burs, demonstrating how and when they can be used to achieve controlled and predictable access preparation. But the focus will not simply be on which bur to use. For each instrument, Dr. Farnararo will explain the clinical rationale behind the choice:

Why this bur?

Why at this stage?

Where should it be used?

In which direction?

How much dentin should be removed?

What anatomical information are we looking for?

When should we stop?

When should we change instruments?

Understanding the “why” behind the bur selection allows clinicians to understand and adapt the SAC concept rather than simply reproduce a sequence.

From Radiograph to Access

A predictable access begins before the first bur touches the tooth. The SAC workflow starts with a systematic analysis of the preoperative radiograph, using the available anatomical information to anticipate canal position, angulation, calcifications, overlapping structures and potential difficulties. Under the operating microscope, this information is progressively translated into a controlled clinical approach. The objective is not simply to create an opening. It is to create the right opening for that specific tooth.

Preserve - Without Compromising Disinfection

Minimally invasive endodontics should not mean sacrificing visibility, access or effective instrumentation for the sake of creating a smaller cavity. The SAC concept is based on a different balance: Preserve what does not need to be removed. Remove what is necessary to achieve predictable disinfection.
“We shape only what we need to disinfect.”

What You Will Learn:

The fundamental principles of the SAC.

How to systematically analyze the preoperative radiograph before starting the access.

How to design the access according to the internal anatomy of the tooth.

Which specific burs can be used during the different stages of access preparation.

The clinical rationale behind each bur selection.

How to control the depth and direction of dentin removal.

How to integrate the operating microscope into the SAC workflow.

How to recognize when an access is excessively invasive.

How to recognize when an access has become too conservative and is compromising visibility or instrumentation.

How to approach calcified and challenging canal orifice locations.

How to adapt the SAC workflow to different anatomical situations.

How an intelligently designed access can facilitate subsequent instrumentation and disinfection.

Not Just a Smaller Access. A Smarter Access.

The SAC is not simply a technique for making smaller access cavities. It is a clinical decision-making concept. Because the most conservative bur is not necessarily the smallest one. It is the bur that allows you to remove exactly what is necessary — and nothing more.
