Six Lessons Approach Podcast by Dr. David Alleman

Post-operative sensitivity is preventable when you understand the cause. When dentin is exposed, pulpal fluid moves through pulpal tubules, eliciting a feeling of pain for the patient. This exposed dentin and the resulting pain can come from poor seals in adhesive restorations or improper diagnosis of cracks and caries during treatment. In this episode of the Six Lessons Approach Podcast, Dr. David Alleman, DDS, discusses the history of research around dentinal pain, the sources of post-operative sensitivity and how to avoid sensitivity in your restorations.Send us Fan MailRegister before December 1 for 20% off any 2027 Alleman Center Training program with code SLA2027:Upcoming training programs:January 25: Online Biomimetic Mastership startsMarch 24-27: In-Person Biomimetic MastershipApril 23-24: SLA Workshop + Isolation/DME IntensiveReady to learn sooner?

Do dental liners and bases benefit a restoration? Originally developed for retention restorations, liners and bases were believed to seal the dentinal tubules to protect the pulp, but later research showed their ineffectiveness. As restorative dentistry transitioned to adhesive materials and protocols, their use continued, but are they still necessary to seal the pulp? In this episode, Dr. David Alleman, DDS, discusses the research and effectiveness of liners and bases, and how the right adhesive protocols can render them unnecessary by using your dentinal bonding system to seal the tooth instead.Articles referenced in this episode:Brannstrom M.

Biomimetic dental materials mimic a natural tooth’s flexibility and cohesive strength. How does this help a restoration long-term? These materials, when used with the right techniques, work with the remaining tooth structure around the restoration, rather than in opposition to it, like with materials that are too stiff, poorly bonded or stress weaker areas of the tooth.In this episode, Dr. David Alleman, DDS, dives into dentinal bonding systems, flowable composites and fiber, discussing what makes them biomimetic, how they are developed and researched and their benefits in a restoration. Articles referenced in this episode:Akimoto N, Takamizu M, Momoi Y. 10-year clinical evaluation of a self-etching adhesive system.

What materials should you use to maximize adhesive strength, restoration longevity and tooth conservation? While how you use the materials — your techniques – are more important than the materials themselves, materials do still make a difference in restorative outcomes. In this episode, Dr. David Alleman, DDS, discusses zirconia, ceramic and composite and these materials’ interaction with natural tooth structure.Articles referenced in this episode:Urabe I, Nakajima S, Sano H, Tagami J.

Fiber placement in restorative dentistry: Does it stop cracks, improve bonds or just add time to your restorative process? Dr. David Alleman, DDS, dives into the history of dental fibers, including Ribbond, Everstick Net and Ever-x Posterior, their uses in different clinical settings, and the research that shows how they support the restoration long-term. Articles referenced in this episode:Belli S., Et al.

Cracks put teeth at risk of infection and fracture if left untreated, but treating cracks in teeth can create many challenges for practitioners. Removing cracks without good magnification, visibility and an understanding of crack propagation puts the nerve and critical tooth structure at risk. Once the crack is removed, the non-standard defect requires specific techniques to bond to deep areas of the tooth while maintaining a strong bond.Dr. David Alleman, DDS, first began researching treatment options for cracks because he recognized that full coverage crowns weren’t yielding predictable results. Adhesive dentistry had the potential to offer a more predictable alternative, but the protocols didn’t exist for practitioners. So he formulated those protocols for predictable crack treatment himself. Articles referenced in this episode:Belli S., Et al.

Dentists have been attempting to treat cracked teeth for decades, with the goal of alleviating patient pain and conserving teeth through restorative treatment. But as Dr. David Alleman, DDS, describes in this episode, “it’s a coin toss of success.” Methods such as retention to hold the crack together or bonding over the crack with adhesion are unpredictable. Sometimes the treatment works, and sometimes it doesn’t, leaving patients and practitioners frustrated. The solution: treat cracked teeth like engineers have been treating cracks for over a century. The challenge: applying these techniques to a biological environment and accounting for bacteria, dentin hydration and dental adhesives.Dr. David Alleman, DDS, discusses the history and treatment protocols for predictable cracked tooth treatment in this episode of the Six Lessons Approach podcast.Articles referenced in this episode:Brannstrom M.

The most minimally invasive dentistry is early diagnosis and treatment. Dr. David Alleman created the 1-2-3-4 risk assessment so he could better diagnose teeth that were at risk of fracture or decay to prevent large fractures or carious lesions under the restoration. In this episode, Dr. Alleman discusses research into the structural integrity of different preparations and how practitioners can use this research to prevent cracks and marginal leakage before they pose a risk to the tooth.Articles referenced in this episode:Larson TD, Douglas WH, Geistfeld RE.

Treating cracks in teeth can still feel ambiguous for many dentists. Is it better to observe? Is it better to crown? Is there a less invasive treatment option? In this episode, Dr. David Alleman discusses a key piece of research that offers practitioners more insight into crack diagnosis and treatment: cracks that cause decay.Occlusal effect caries is a carious lesion that forms from cracks that extend into dentin, creating a pathway for bacteria to enter the tooth. These cracks, called peripheral rim fractures, occur mostly around large restorations that leave the surrounding tooth structure unsupported, making crack initiation easier in the tooth. By understanding how these cracks form, practitioners can better learn how to detect and restore teeth affected by peripheral rim fractures.Articles referenced in this episode:Milicich G, Rainey J T.
