    Rotary vs Reciprocating Files – The Endo Showdown with Samuel Johnson Part 1 – PDP270

    Rotary or reciprocating files — which should you actually be using? Is one safer than the other? Does reciprocation really reduce file separation? Are you choosing your system because it suits the canal anatomy, or because it is simply the one you were taught? Endodontic file systems can feel like a maze of brands, tapers, alloys, motions and marketing claims. But beneath all that noise, the real question is much more practical: what is your file doing inside the canal, and what compromise are you accepting? In this episode, Dr Samuel Johnson returns to unpack the Endo Showdown: rotary versus reciprocating files. We cover file motion, glide paths, shaping philosophy, NiTi metallurgy, cyclic fatigue, torsional fatigue, and why no system is perfect. https://youtu.be/HfWDBbNgjsA Watch PDP270 on YouTube Protrusive Dental Pearl A palliative root canal can be useful for an unrestorable tooth if disinfecting the canal allows infection to heal and natural bone to recover before extraction and future implant planning. ⚠️ Do not dismiss root canal treatment purely because the tooth is not a long-term functional restoration. ✅ Where appropriate, consider whether endodontic disinfection could improve the future implant site by allowing natural bone healing. Key Takeaways The purpose of shaping is not simply to scrape canal walls; it is to create space for irrigant flow. Irrigation is the most important part of root canal disinfection. Rotary files move in a continuous 360-degree rotation. Reciprocating files cut in one direction and reverse before excessive stress builds up. Modern reciprocation is designed to cut, release and gradually progress apically. File choice is not just about motion; metallurgy, taper, design and operator experience all matter. NiTi hand files with strong shape memory may be problematic in curved canals because they want to straighten. Martensitic heat-treated files are more flexible and can better follow canal curvature. Unwinding flutes are a warning sign that a file may be close to separation. Inspect files regularly during treatment, especially in curved, calcified or difficult canals. A glide path is essential before introducing larger rotary or reciprocating files. Without a glide path, a shaping file may create its own path, risking ledging, transportation or perforation. “Grabby” files pull themselves into the canal; this can be useful in experienced hands but risky if forced. Reciprocating systems can feel simpler and safer, but they are not foolproof. Cyclic fatigue happens when a file repeatedly bends around a curve until microcracks form. Torsional fatigue happens when part of the file binds while the motor continues to turn.

    A Practical Guide to Modern Caries Management Part 2 – Peptides, SDF, Hydroxyapatite and Xeristomia! – PDP269

    Should we still be drilling early caries lesions? Where do peptides, resin infiltration, fluoride varnish and SDF actually fit in modern practice? Is hydroxyapatite toothpaste a genuine alternative to fluoride, or just another dental trend? And when you see that suspicious grey occlusal shadow, do you seal it, explore it, or actively surveil it? In part two of this modern caries management episode, Jaz continues the conversation with Prof. Avijit Banerjee on minimal intervention dentistry. This episode moves beyond diagnosis and communication into the practical management of early and progressing caries lesions, including peptides, SDF, hydroxyapatite toothpaste, fissure sealing, xerostomia, root caries and selective caries removal. https://youtu.be/dGt7FW7C4N0 Watch PDP269 on YouTube Protrusive Dental Pearl Use the Contemporary Caries Management Implementation Pack as a chairside aid to turn the episode into daily clinical action. ⚠️ Learning the evidence is not enough if it never makes it into your patient conversations, risk assessment or treatment planning. ✅ Print it, laminate it, and use it to support communication, diagnosis, active surveillance and minimally invasive decision-making. Disclaimer: This is an educational resource produced by Team Protrusive, derived from the two-part Protrusive Dental Podcast episode featuring Prof. Avijit Banerjee. Its contents were not written, reviewed, or endorsed by Prof. Banerjee; they represent Team Protrusive’s own interpretation of the material discussed. It is intended as a practical summary and is not a substitute for primary sources. We strongly encourage all clinicians to consult the latest Clinical Practice Guidelines before making treatment decisions. Key Takeaways: Peptides are designed to infiltrate early enamel lesions and create a scaffold for mineral deposition. Peptide technologies still need minerals from saliva, toothpaste, mouthwash or other sources to work. Fluoride supports remineralisation; it acts more like the “mortar” than the “bricks”. Early E1 lesions are usually managed with prevention, fluoride, oral hygiene, diet control and biofilm control. Deeper enamel lesions, such as progressing E1 or E2 lesions, may be suitable for resin infiltration or peptide infiltration. SDF is better suited to cavitated lesions where arrest and stabilisation are needed. In the UK, SDF is licensed for dentine sensitivity, so caries arrest is an off-label use. SDF can be very useful for children, older adults, medically compromised patients and care-home patients. The main downside of conventional SDF is black staining, especially on anterior teeth. Hydroxyapatite toothpaste has more science behind it than charcoal-style fad toothpastes. Fluoride toothpaste remains the preferred baseline recommendation when patients are happy to use fluoride. A suspicious grey occlusal lesion should be assessed in the context of the patient’s overall caries risk. In selected cases, a tiny exploratory opening can act like a diagnostic biopsy. Sealing fissures on the same tooth being restored can be sensible when the fissure pattern is deep. For severe xerostomia and root caries risk, consider high-fluoride regimes, close recalls, trays or dentures as carriers for remineralising agents.

    A Practical Guide to Modern Caries Management – MIOC and MID Part 1 – PDP268

    If you showed the same bitewing to 10 dentists, would they all agree on whether to pick up the drill? Why does the word monitoring mean nothing to a patient — and how does swapping it for active surveillance change everything from your notes to your indemnity to your government policy meetings? Is it overtreatment to act on an E2 lesion — or is “watch and wait” actually the lazy answer dressed up as minimally invasive? And what should you actually do with AI caries detection that flags shadows your eye doesn’t see? In this episode, Professor Avijit Banerjee — Professor of Cariology & Operative Dentistry at King’s College London, Honorary Consultant at Guy’s & St Thomas’, and First Dean of the Faculty of Dentistry at the College of General Dentistry — sits down with Jaz for what is genuinely one of the most important caries conversations on the podcast. Part one of two. Avijit doesn’t do soft answers. The drill-fill-bill model is broken. “Monitoring” needs to go. “Treatment planning” is antiquated terminology medics dropped twenty-five years ago. And AI in caries diagnosis? Useful — but the moment it gets things wrong, you are the one with indemnity, not the software. What you walk away with is a framework (MIOC), a decision filter (three factors that decide whether to pick up a bur), and a vocabulary shift you can implement tomorrow. Part two covers peptides, SDF, hydroxyapatite, stepwise excavation, and managing caries in xerostomia. https://youtu.be/YriLo8_hXNw Watch PDP268 on YouTube Protrusive Dental Pearl: Delete the Word “Monitor” from Your Vocabulary Stop saying monitor. Start saying active surveillance. ⚠️ Active surveillance must not mean passive delay — document your reasoning, risk assessment, and what would trigger intervention. ✅ Explain it to patients as structured, proactive care: clinical checks, radiographs, risk review, behaviour support, and timely action if things change. Key Takeaways Minimum intervention oral care is bigger than minimally invasive dentistry. MIOC is prevention-based, person-focused, susceptibility-related, and delivered by the whole oral healthcare team. MID is only one part of MIOC: operative dentistry when a tooth actually needs intervention. The four MIOC domains are: identify the problem, prevent lesions and control disease, provide minimally invasive operative care, then reassess. A care plan is more useful than a treatment plan because it includes justification, prevention, behaviour change, and review. Ask patients what matters to you, not just what’s the matter with you. Cavitation, cleansability, and lesion activity should guide whether to intervene operatively. A cavitated lesion that cannot be cleaned is much more likely to remain active. Smooth surface lesions may sometimes be made cleansable without conventional drilling. Restorations are not just about filling holes; they help recreate a cleansable tooth surface. There is no single perfect caries detection technology — clinical examination and good radiographs remain fundamental. If using NIRI, fluorescence, scanners, or AI, understand how the technology works and where it fails. AI should support diagnosis, not replace clinical judgement. For uncertain early lesions, triangulate: clinical findings, radiographs, risk, technology, and patient factors. Proximal resin infiltration has a role in the right patient and situation, especially as part of a wider prevention-led strategy.

    Realism, Mistakes and Radical Honesty in Dentistry – IC074

    Why does dentistry on social media look so perfect? Are those flawless before-and-after cases the reality of everyday practice—or just the highlight reel? And why aren’t we talking more openly about the failures, frustrations, and imperfect outcomes that every dentist experiences? In this episode, Dr Artem Mkrtichyan joins Jaz for a refreshingly honest conversation about the realities of modern dentistry. Known for his candid and relatable social media posts, Dr. Artem has built a following by sharing what many dentists think—but rarely say out loud: dentistry is hard, results aren’t always perfect, and social media often paints an unrealistic picture of the profession. https://youtu.be/uTKaeewgrgE Watch IC074 on YouTube Key Takeaways Social media has become a powerful tool for dentists to connect and share experiences. Mistakes in clinical practice are common and should be openly discussed. Rural practice may not always lead to higher income as expected. Success in dentistry is subjective and varies for each individual. Continuous learning and skill development are crucial for career growth. Financial freedom in dentistry is not guaranteed and varies widely. Networking and mentorship can significantly impact career progression. Social media can be leveraged to attract patients and build a personal brand.

    10 Occlusion Pearls That Will Blow Your Mind – PDP267

    Why does occlusion feel so confusing at dental school? What if the problem is not that occlusion is too complex, but that it was taught in the wrong order? How do you make sense of worn teeth, bite scans, shimstock, leaf gauges, provisionals and T-Scan without getting overwhelmed? And which small ideas can genuinely change the way you diagnose, plan and restore? In this episode, Jaz is joined by Dr. Mahmoud Ibrahim for a brilliant occlusion-focused conversation. They each bring five clinical “pearls” that helped occlusion finally click for them — from facially generated treatment planning to checking the contralateral side, muscle palpation, provisionals and digital occlusal data. https://youtu.be/REQ_L5NNEF4 Watch PDP267 on YouTube Protrusive Dental Pearl Create a PowerPoint or Keynote library of your clinical photos so you can quickly show patients relevant examples during consultations. ⚠️ Avoid hunting through random folders chairside — it feels clunky and breaks the flow of the conversation. ✅ Build a scrollable visual library of cracks, before-and-afters, complications, direct restorations, overlays, crowns and consent examples to support clearer patient communication. Key Takeaways Occlusion becomes easier when it is placed inside the treatment planning sequence, not treated as a separate subject. Facially generated treatment planning starts with where the upper teeth need to be for aesthetics. Once the central incisors are planned, the rest of the occlusion becomes easier to organise. Worn teeth that are still in occlusion are often in the wrong position. Anterior wear may be caused by tooth position, contact time, contact force, or a combination of all three. Gingival levels can reveal whether worn lower incisors have over-erupted. Digital bite scans are useful, but they are not always a perfect representation of the patient’s bite. Shimstock remains one of the most valuable and inexpensive tools for checking true occlusal contacts. After fitting a restoration, checking the contralateral side first can reveal whether the new restoration is high. Anterior guidance should be steep enough to separate the back teeth, but shallow enough to allow the lower incisors room to move. Muscle palpation should assess the quality and symmetry of contraction, not just whether the muscles exist. Always assess the opposing tooth before placing composite, ceramic or an indirect restoration. A leaf gauge can help create a more repeatable jaw position when planning more complex occlusal cases. Provisionals are essential for testing aesthetics, function, vertical dimension and occlusion before committing to final restorations.

    Posterior Composites Done Right – PDP266

    Are we overcomplicating posterior composites? Are those beautiful fissures and stains actually helping the patient… or just us? Why does that “perfect” restoration suddenly need 20 minutes of occlusal adjustment after rubber dam removal? And how can we make functional, predictable composites without burning time or stress? In this episode, Dr. Vishaal Shah shares a refreshingly practical approach to posterior composites. From understanding the basics, to simplifying anatomy and improving efficiency, this is a grounded, clinically focused conversation on how to deliver restorations that actually serve the patient. https://youtu.be/tdkTxzcloN0 Watch PDP266 on YouTube Protrusive Dental Pearl Match your composite anatomy to the patient’s dental age and opposing dentition before you start building. ⚠️ Overbuilding cusps in a worn dentition will create occlusal interferences and wasted adjustment time ✅ Assess space, wear, and occlusion first—then design the restoration accordingly Key Takeaways Function, efficiency, and occlusal compatibility should guide every restoration Dental age (wear) is more important than chronological age when planning anatomy Always assess the opposing tooth before designing cusps and fissures Use the whole arch—not just the contralateral tooth—as your anatomical guide Follow the central fissure line across the quadrant to orient your restoration Avoid textbook anatomy in worn dentitions—adapt to what’s present Large MOD composites often act as interim restorations before crowns Build proximal walls first to establish contact and control final contour Use composite slump (with a microbrush) to naturally form proximal curvature Base layer height should match the deepest fissure level of adjacent teeth Map out fissures and cusps before building to improve accuracy and speed Start with the most difficult cusp first to reduce fatigue-related errors Proper planning before drilling reduces occlusal errors and remakes Highlights of the Episode: 00:00 Teaser 01:08 Introduction 01:50 Pearl: Matching Anatomy to Dental Age 05:32 Posterior Composite: Start with Basics, Not Complexity 10:42 Efficient Approach to Large Restorations 14:22 Efficiency vs Ideal Posterior Restorations 19:25 Building Proximal Walls First 20:55 Using Putty Stents for Missing Cusps 23:54 Midroll 27:15 Using Putty Stents for Missing Cusps 27:25 Matrix System Selection 28:06 No Pre-Wedging Philosophy 29:06 Managing Composite Overhangs 30:46 Matrix Ring Differences 32:45 Interjection 37:03 Matrix Ring Differences 37:43 Proximal Wall Technique for Posterior Composite 41:03 Base Layer Strategy in Posterior Restorations 42:23 Mapping Anatomy Before Composite Build-Up 43:13 Cusp Build-Up Approach 45:03 Minimal Adjustment Philosophy 46:43 Final Philosophy: Keep It Simple 48:00 Learning Opportunities 49:54 Outro 🔥 Want to level up your posterior composites?

    Why We Need to Take MRIs for TMJs! – PDP265

    When is it appropriate to consider an MRI for your TMD patient? What’s actually involved in MRI of the TMJ? Can you use any MRI machine, or is the choice of imaging center crucial? And who should be reporting on these scans — does it really matter? (Hint: yes, it does!) Dr. Kevin Lotzof, a straight-talking radiologist, joins Jaz for a controversial deep dive into the role of MRI in Temporomandibular Disorders. While many experts downplay its importance, Kevin argues that TMJs are under-imaged and under-diagnosed — and that we may be missing critical pathology. They explore the practicalities of imaging, how to set expectations with your patients, and why strong but differing views in TMD care can ultimately help you refine your own clinical approach. https://youtu.be/-yo_Qx4Zg5Q Watch PDP265 on YouTube  Protrusive Dental Pearl: Adopt the mindset of “Find the cancer today.” When carrying out examinations—whether soft tissue or extraoral—approach it with the intention of detecting oral or skin cancers early. This mindset helps clinicians look beyond just teeth, catch unusual or suspicious lesions, and potentially save lives. Key Takeaways TMJ is often overlooked but is crucial for overall health. MRI is essential for accurate TMJ diagnosis. Cone beam CT cannot replace MRI for TMD assessment. Patients with headaches may have undiagnosed TMD. Education on TMJ imaging is lacking among dental professionals. Asymptomatic patients should still be scanned for TMJ issues. The quality of imaging directly impacts diagnosis accuracy. Patients often feel anxious about MRI procedures. Understanding patient perspectives can improve care. There is a need for better collaboration between dentists and radiologists.

    Zirconia vs. Titanium: The Implant Debate – PDP264

    Is titanium still the gold standard for implants? Are zirconia implants just hype from biological dentistry… or something more? Do ceramic implants really integrate as well as titanium? And should we already be offering patients a choice? Zirconia implants are no longer a fringe concept—they’re entering mainstream conversations. In this episode, Dr. Pav Khaira returns to break down the science, clinical decision-making, and real-world application of zirconia vs titanium implants. From corrosion and osteoimmunology to occlusion and case selection, this is a practical, evidence-led discussion for clinicians navigating modern implant options. https://youtu.be/-RCvf2KOdSc Watch PDP264 on YouTube Protrusive Dental Pearl: Thriving in Challenging Times 💡 Prioritize quality sleep—it sharpens decision-making, improves mood, and reduces irritability (6–7 solid hours beats longer, disrupted sleep). ➡️ Remember, stress comes from how we respond, not the situation itself—focus on what you can control and let go of the rest. 📢 Lean on your support system and make time for reflection and gratitude—they help reframe pressure and build resilience. Key Takeaways Zirconia implants integrate just as well as titanium, with comparable clinical outcomes Early healing may be slightly faster around zirconia, but long-term results are similar Titanium can corrode over time, releasing particles linked to peri-implantitis Zirconia does not corrode, removing this biological risk factor Modern implant thinking focuses on osteoimmunology, not just osseointegration Zirconia implants are often one-piece → no microgap and improved crestal bone stability Surgical placement must be highly precise—zirconia is less forgiving than titanium Guided osteotomy is strongly recommended for ceramic implants Fracture risk in modern zirconia implants is low when manufactured correctly Hot isostatic pressing significantly increases zirconia strength and reduces defects Case selection is critical—limited bone or complex angulation may favour titanium Zirconia implants are typically cement-retained only Excess cement remains a risk factor for peri-implant disease → manage carefully Zinc phosphate cement is useful due to radiopacity and bacteriostatic properties Angled screw correction (titanium) is predictable only up to ~15 degrees Patient preference for metal-free dentistry is a growing driver of zirconia demand Episode Highlights 00:00 Teaser 00:49 Introduction 02:32 Protrusive Dental Pearl: Advice for Dentists during challenging times 05:14 Basics: What Are Implants Made Of? 07:13 Osseointegration: Zirconia vs Titanium 08:28 Why Zirconia?
