On Friday and Saturday, the seminar will be from 9 a.m. to 1 p.m.
Tuition is $ 500. per person. Registration at the door, add $20. per person, space permitting. Cancellations receive refunds with at least 14 days advance notice or with less notice, if we have someone to take your place.
Tuition payment: Payment can be made by check (preferred method) or credit card. If you would need to cancel, refunds for tuition paid by credit card are subject to deduction of our banking costs. These costs are avoided should you cancel after paying tuition with a check.
Since our office is closed during these COVID-19 times, please call to let us know that you are sending a check (510-483-2411, after 8am Pacific time please) and we will reserve space for you and e-mail the necessary hotel discount codes.
Alternatively you may securely FAX (510-652-8729) your registration using credit card or just write in “sending check”.
We accept credit cards (AmEx, Visa and Mastercard) but we will defer posting the charge until about a month or two before the seminar. Our concern is that COVID-19 may force us to cancel. In that event, we would want to make a full refund. If we have to process and later refund credit cards, our bank processing costs are a big concern. (Posting and refunding costs us upward of 6%).

Other seminars where Dr. Bertolotti will be presenting:
International webinar, our first one!
Ray Bertolotti will partner with two of our favorite speakers, both dental innovators, Graeme Milicich and Geoff Knight. The webinar scheduled for Saturday June 6, in the afternoon, in the USA time zone. “Down under”, where the other speakers are based, it will be Sunday morning. We are planning 3.5 hours but we are guessing that discussion time may extend it a bit longer.
We titled our webinar “Controversial Clinical Concepts”. We expect a practical and thought-provoking 3.5 hour session.. Following the 3 presentations, delegates will have the opportunity for a live Q and A interaction. We kept the tuition very affordable, only US$63. There will be 4 hours CE credit . This LIVE webinar is scheduled as follows:
United States / West Coast Time // Saturday June 6th from 4.00 pm - 7.30 pm
Australia Eastern Standard Time // Sunday June 7th from 9.00 am -12.30 pm
New Zealand Standard Time // Sunday June 7th from 11.00 am - 2.30 pm
For USA and Canadian dentists, Fifth Quarter Seminars will certify the 4 C. E. credit hours. Please note that Fifth Quarter Seminars is not taking the registrations, to avoid possible duplication.

WEBINAR topics summary:
The Six Fracture Modes of Teeth: How misdiagnosis can lead to incorrect treatment and failed treatment outcomes.
Graeme Milicich BDS
Have you noticed how busy we are as a profession dealing with fractured teeth. Why do we see so many fractured teeth? Sadly, there are some critical micro-structures in teeth that we never got taught about at Dental School.
A tooth essentially behaves like a compression dome (like the Pantheon Dome, or St Pauls Cathedral.) The behaviour of a dome helps keep it and underlying structures in compression. A tooth is designed by Mother Nature to absorb and distribute compressive forces. Tensile forces are dangerous to a tooth because dentin and enamel have not been designed to cope with excessive tensile forces. Allowing tensile forces to do their damage leads to six fracture modes that have to be managed in different ways to restabilize the tooth. This means the various fracture modes have to be recognized to ensure the correct treatment modality is chosen, otherwise the treatment can fail.
The Six Fracture Modes of Teeth.
- Occlusal effect fractures – vertical in the enamel peripheral rim
- Occlusal effect fractures – occlusal abfraction – loss of tooth between peripheral rim enamel and the restoration
- Vertical mesio-distal fractures
- Oblique cusp fractures – most common form
- Randomly oriented Poisson Effect vertical fractures in the dentin core
- Catastrophic point overload fractures (trauma and foreign objects in food)
There is one critical part of the Pantheon dome, the oculus. If a single piece of masonry was removed from the oculus, the whole Pantheon Dome would collapse.
There are also structures within the enamel “compression dome” of a tooth that are critical to its functional stability. Removing the wrong ones exposes the underlying dentin to tensile forces it was never designed to deal with. Constant cycling through mastication leads to various fracture mechanisms developing in the tooth, both in enamel and dentin. One such structure was reported by Dr Tim Rainey in 1996.
This structure is called the sub-occlusal oblique transverse ridge. It is a sub-surface, uninterrupted band of enamel that runs from the disto-buccal to mesio-buccal cusps on lower molars. Removing the wrong parts of the occlusal enamel exposes the underlying dentin and the peripheral rim of enamel to tensile forces that lead to crack propagation over time. It is the occlusal enamel that is most critical to the mechanical stability of the tooth, we remove it at our peril.
Look at what happens to tooth flexure when simple slot preps are joined together into an MOD by removing the occlusal enamel.
Current paradigm shifts in adhesion dentistry.
Raymond L. Bertolotti DDS PhD
Learning adhesion and then trusting adhesion leads to easier, faster, more profitable and better dentistry. Adhesion dentistry is low stress for the dentist and fun to provide!
One exciting application of adhesion is cantilevered, bonded zirconia bridges, done with minimal to no tooth preparation. In a well documented study, clinical success was 100% at 10 years, if we count as successful the 5% which debonded and were successfully re-bonded. The debonds were mostly due to trauma. There was zero zirconia breakage. These bridges are a perfect solution for missing lateral and central incisors. Understanding the properties of different zirconia formulations as well as zirconia adhesion is critical for clinical success. (I just laugh when I hear from labs and dentists that “zirconia cannot be bonded”.)
Another exciting application of adhesion is “compression dome” ceramic restorations, as advocated by Milicich. Retaining an enamel ”biorim” around the tooth virtually eliminates tooth fractures, especially important for endodontically treated teeth which should never be crowned! A new bulk fill composite, with revolutionary polymerization technology, directs the shrinkage toward the tooth, greatly facilitating final tooth preparation for bonded compression domes. Localized defects extending gingivally are be quickly corrected by “margin elevation”, reducing the need to remove tooth structure at the expense of the biorim. Gaps and leakage at the margins, which lead to so-called “recurrent caries”, are eliminated. (Actually eliminated is the clinical failure which occurs before the patient leaves the chair!)
Management of initial caries
Geoff Knight BDS, PhD
There are two main reasons for tooth preparation:
- Firstly to intervene in the ongoing destruction caused by dental caries
- Secondly to repair a previously failed restoration
The aim of restoring a carious tooth is to arrest the decay process by working with the natural healing abilities of the dentine pulp complex (arrested caries) with minimal interference to the physical structure of the tooth, so as to stabilize and bring it back into normal function, ideally with minimal aesthetic change.
The aim of restoring a failed restoration is to manage any underlying caries and then reconstruct the missing tissue with sufficient strength so that the tooth becomes a functioning and aesthetically integrated member of the dentition. The challenges encountered here depend upon the amount of preparation done to the tooth to treat the initial caries.
Initial caries are most often found on:
- Occlusal and buccal surfaces
- Interproximal surfaces
- Multiple surfaces
