The Dr. Phil Klein Dental Podcast

Is your composite workflow actually giving patients the best possible outcome, or are small technique errors quietly costing you bond strength, longevity, and chairside efficiency?
Dr. John K. Zalesky, DMD, MBS, FICOI, FAGD brings over a decade of clinical and academic experience to this conversation. He holds a Master of Biomedical Science from the University of Medicine and Dentistry of New Jersey and his DMD from Nova Southeastern University College of Dental Medicine, followed by a General Practice Residency at Denver Health Medical Center and advanced chief residency training at the University of Colorado School of Dental Medicine focusing on implants and complex prosthodontics. A Fellow of both the Academy of General Dentistry and the International Congress of Oral Implantologists, Dr. Zalesky is part-time faculty at the University of Colorado School of Dental Medicine, Past President of the Colorado Constituent of the Academy of General Dentistry, and has been recognized as one of Colorado's Top Dentists and a 2023 Top 40 Under 40 honoree by Incisal Edge magazine.
In this episode, Dr. Zalesky breaks down how composite dentistry has evolved from unwieldy multi-shade systems to streamlined universal composites, and why that simplification does not mean a compromise in aesthetics or durability. The conversation covers the science behind selective etching and eighth-generation universal adhesives, the clinical rationale for composite warming, and the most overlooked curing errors that undermine even the best restorations. Dr. Zalesky draws on his dual role as clinician and educator to offer practical, protocol-level guidance that is directly applicable to everyday practice.
Episode Highlights:
Universal composites have redefined shade selection by condensing armamentaria to body and enamel shades across a core range, with research and clinical experience suggesting that A2 and A3 shades cover approximately 85 to 90 percent of patients. This simplification reduces inventory overhead and expired material waste while still enabling characterization for anterior cases through layering techniques.
Selective etching with phosphoric acid applied exclusively to enamel, combined with a self-etching universal adhesive on dentin, represents a significant shift from older total-etch protocols. This approach preserves the inorganic mineral substrate on dentin for MDP chemical bonding while still achieving strong resin tag formation in enamel, and clinicians report a dramatic reduction in postoperative sensitivity as the most immediate benefit.
Composite warming alters the physical properties of the material by increasing kinetic energy and monomer conversion, resulting in greater depth of cure and improved adaptation at the cavosurface margin. The warmed material behaves more like a flowable without fully becoming one, and clinicians must work efficiently since the material begins reverting to its original viscosity approximately two minutes after removal from the heat source.
Curing light calibration is identified as the single most overlooked variable in composite technique, with an uncalibrated or aging light capable of leaving an incompletely polymerized layer at the depth of a preparation. Proper technique also requires adequate curing time per the specific light's manufacturer guidelines, multi-directional curing including buccal, lingual, and occlusal after band removal, and maintaining the light tip stationary over the restoration throughout the curing cycle.
Building an effective restorative armamentarium from scratch should prioritize a composite warmer, high-quality composite placement instruments, a reliable multi-directional polishing system including discs for anterior work, and a calibrated curing light. A growing body of research also suggests that traditional micro brushes shed particles during adhesive application at a rate that measurably compromises bond strength, making conventional paint-style brushes a preferred alternative for adhesive delivery.
Perfect for: general dentists at any career stage looking to modernize their composite workflow, dental residents building their restorative foundation, and dental educators seeking evidence-informed talking points on adhesive systems and curing technique.
If you have ever wondered whether your curing light, bonding protocol, or composite selection is quietly limiting your outcomes, this episode gives you the clinical framework to find out and fix it.

How do young dentists establish credibility and build case acceptance for high-end cosmetic work when competing against decades-experienced clinicians?
Dr. Luis Abrahante is a cosmetic and implant dentist practicing in Mountain Brook, Alabama, near Birmingham. After graduating from the University of Alabama in 2021, he has built a thriving fee-for-service practice in just three years, specializing in aesthetic dentistry, smile design, and comprehensive full mouth reconstruction. Dr. Abrahante holds memberships in the American Dental Association, American Academy of Facial Esthetics, American Academy of Cosmetic Dentistry, and earned membership by award in the International Congress of Oral Implantologists. He is one of only three members of the American Society for Dental Aesthetics in Alabama and has received prestigious recognition including the American Academy of Orofacial Pain Outstanding Award and the Academy of Operative Dentistry Award. Beyond clinical practice, he contributes as a lecturer, publishes in national journals, and serves as a product evaluator.
This episode explores how Dr. Abrahante overcame the biggest challenge young cosmetic dentists face: convincing patients to invest in comprehensive treatment when you lack decades of reputation. His solution centers on extensive clinical photography—not just before and after images, but detailed interim photos documenting every procedural step. This approach has dramatically improved case acceptance while building patient trust and engagement in treatment planning.
Episode Highlights:
Clinical photography workflow using Canon T8i with 100mm lens and Godox twin flashes creates comprehensive case documentation. Taking interim procedural photos alongside traditional before/after images increases patient engagement and case acceptance by demonstrating technique transparency and building trust with younger practitioners.
No-prep veneer case selection requires understanding occlusion, tooth alignment, and proper patient screening for optimal outcomes. Most cases require minimal preparation around incisal edges or distal angles, with feldspathic veneers as thin as 0.2mm achieving undetectable margins when properly polished at the gingival interface.
Digital smile design workflow incorporates comprehensive photography, intraoral scanning, and lab-fabricated STL files for 3D printing templates. Chairside mock-ups using Luxaflow composite material demonstrate proposed results in real-time, often achieving immediate case acceptance during the consultation appointment.
Indirect restoration preference over direct composite includes ceramic inlays and onlays for larger restorations, citing elimination of polymerization shrinkage, improved longevity, reduced post-operative sensitivity, and superior aesthetics. Chair-side milling capabilities are maintained but laboratory fabrication is preferred for optimal workflow efficiency.
Fee-for-service practice development in upscale demographics requires strategic location selection and systematic insurance plan elimination. Practice renovation focusing on lighter flooring, updated baseboards, and brighter paint schemes creates modern aesthetic perception that patients consistently notice and comment upon.
Perfect for: Young dentists building cosmetic practices, established practitioners seeking case acceptance strategies, and dental teams interested in photography integration and premium practice development.
Discover how strategic clinical documentation and patient education can accelerate cosmetic practice growth regardless of your years in practice.

What does it really take to preserve pulp vitality in a severely decayed posterior tooth — and how does your handpiece factor into that outcome?
Dr. Anna Paholiouk is a restorative dentist practicing in Orange County, California, whose clinical philosophy is rooted in minimally invasive advanced adhesive dentistry based on biomimetic principles. She serves as Adjunct Faculty at the University of Southern California Herman Ostrow School of Dentistry — the same institution from which she graduated — contributing to the education and mentorship of the next generation of clinicians. Dr. Paholiouk holds the distinction of being the first and only female Fellow of the Academy of Biomimetic Dentistry, is a Fellow of the International Congress of Oral Implantologists, and has completed well over 1,000 hours of continuing education in pursuit of clinical excellence.
In this episode, Dr. Paholiouk walks through her philosophy of circumscribing the pulp during preparation design, explaining how the goal of preserving nerve vitality dictates every clinical decision — from handpiece selection to isolation protocol. The conversation explores how electric handpieces have evolved to meet the demands of high-magnification, minimally invasive work, and why consistent handpiece maintenance is just as important as the handpiece itself. Dr. Paholiouk offers a remarkably systematic approach to clinical precision that reduces variables, prevents failures, and keeps patients out of the endodontic chair whenever biologically possible.
Episode Highlights:
Biomimetic preparation design centers on circumscribing the pulp chamber rather than removing structure for retention. The three-by-five rule — measuring three millimeters from the contact of an adjacent tooth and five millimeters from the occlusal surface — defines the anatomical zone where the pulp lives and guides how far preparations can safely extend while preserving nerve vitality.
Electric handpieces offer a distinct clinical advantage over air-driven units because RPM can be controlled with a single bur throughout the entire preparation sequence. This allows the clinician to cut at maximum speed, then slow down to a low RPM on a dry field to finalize margins with the same fine diamond, reducing bur changes, improving efficiency, and giving greater tactile control during conservative preps.
Consistent handpiece maintenance is critical to long-term performance, and automation is the most reliable way to eliminate human variability across staff members. Using an automated cleaning and lubrication system after every single procedure — rather than on a scheduled interval — ensures correct oil volume, proper internal gear rotation, and complete purging without relying on individual staff judgment, which has allowed one practice to go over five years without a single handpiece repair.
Rubber dam isolation is non-negotiable in adhesive biomimetic dentistry because adhesion is chemistry, and chemistry requires a controlled environment. Placing a wingless clamp on the most posterior tooth and isolating the full quadrant eliminates saliva contamination, improves visibility with a contrasting dam color, protects the airway during bur use, and removes soft tissue interference — all of which directly support margin integrity and restoration longevity.
Selective caries removal using a caries detection dye requires multiple reapplications and a clear understanding of what is being achieved. The goal is not to remove all stained dentin, but to establish a peripheral seal zone of approximately two to three millimeters of clean enamel, superficial dentin, and the dentinoenamel junction — leaving affected but not infected dentin in place when it is safely distant from the pulp to support remineralization and minimize iatrogenic pulpal exposure.
Perfect for: General dentists looking to evolve their restorative philosophy toward more conservative, adhesive-based care; restorative specialists, dental residents, and dental students interested in biomimetic principles; and any clinician who wants to reduce handpiece-related failures through better maintenance protocols.
If you have ever been told a tooth needs a root canal and a crown before anyone checked whether the pulp was actually vital, this episode will change the way you approach your next posterior restoration.

Are you maximizing your ability to save implants threatened by peri-implant disease? With millions of implants placed annually, peri-implant complications are becoming routine challenges in every practice.
Dr. Robert Convissar brings over four decades of clinical experience and pioneering expertise in dental laser technology to this essential discussion. A New York City-based general practitioner, Dr. Convissar serves as Director of Laser Dentistry at New York Hospital Medical Center of Queens and has authored multiple textbooks including the acclaimed "Principles and Practices of Laser Dentistry," now in its third edition. An international lecturer across 30 countries, he has trained hundreds of dentists in laser applications and oral cancer detection techniques.
This episode provides a comprehensive framework for incorporating laser therapy into peri-implant disease management. Dr. Convissar explains the critical distinction between peri-implant mucositis and peri-implantitis, emphasizing proper diagnosis of etiologic factors before any laser intervention. The discussion covers evidence-based protocols for post-scaling and root planing laser decontamination, optimal wavelength selection, and the essential role dental hygienists can play in laser-assisted therapy.
Episode Highlights:
Proper etiologic factor identification is mandatory before laser treatment, including evaluation of occlusal loading, crown contours, abutment integrity, and home care compliance. Without addressing these underlying causes, laser therapy provides minimal therapeutic benefit regardless of technique or wavelength selection.
CO2 and erbium lasers operate at significantly lower tissue temperatures (100°C average tip temperature) compared to diode lasers (750-1500°C), making them safer choices for peri-implant therapy. This temperature differential reduces risk of thermal damage to implant surfaces and surrounding tissues while providing effective bacterial reduction.
Laser therapy must function as an adjunct to conventional scaling and root planing rather than a replacement. The combination approach provides superior diseased tissue removal and logarithmic bacterial count reduction compared to mechanical debridement alone, leading to enhanced healing outcomes.
Trained dental hygienists can effectively incorporate laser therapy into maintenance protocols when properly supervised and educated. This delegation expands treatment accessibility while creating additional revenue streams for practices already performing comprehensive peri-implant maintenance.
Patient acceptance rates for laser-assisted peri-implant therapy are significantly higher than full-mouth periodontal laser treatment due to implant investment protection motivation. Single-implant laser treatment can serve as an introduction to expanded laser therapy applications throughout the mouth.
Perfect for: General dentists, periodontists, oral surgeons, dental hygienists, and practice owners considering laser technology integration for enhanced peri-implant disease management and revenue diversification.
Discover how laser technology can transform your approach to implant preservation and create sustainable practice growth opportunities.

How do you know when a universal composite is truly enough — and when you need to layer, tint, or cut back to achieve a result that lasts and looks natural? This episode delivers a frank, operatory-level conversation about direct composite dentistry from someone who does it every day in a biomimetic, rubber-dam-isolated practice.
Dr. Tiffani Dunn is a DMD and AAACD Accredited cosmetic dentist — a distinction held by fewer than 400 dentists worldwide — who graduated from the Medical College of Georgia in 2009. She maintains a full-time private practice in Kailua Kona, Hawaii focused on interdisciplinary care and cosmetic dentistry. Dr. Dunn is a Visiting Faculty member at Magne Education in Beverly Hills, an Ambassador for Dental Advisor, a Kois Graduate, a Key Opinion Leader for Ivoclar, and an author and lecturer with deep roots in biomimetic and adhesive dentistry.
In this episode, Dr. Dunn shares how her approach to direct composite has shifted toward biomimetic principles over the past decade, why she relies on rubber dam isolation for virtually every restoration, and how she navigates material selection between universal and traditional layering composites. The conversation covers the clinical logic behind using a single-manufacturer restorative system, how immediate dentin sealing fits into both direct and indirect workflows, and why occlusion — not material selection — may be the most underappreciated factor in long-term composite success. Dr. Dunn is candid about what works in her hands, what she would do over, and what she tells new graduates trying to decide between direct and indirect approaches.
Episode Highlights:
The cutback technique for anterior direct composite involves placing the base composite shade, then removing approximately one to two millimeters of cured material with a fine diamond bur, re-applying adhesive to the prepared surface, and layering tints, stains, or a more opaque composite before finishing. This window approach allows clinicians to customize optical characteristics — including surface striations and depth effects — without abandoning a universal composite system entirely.
Immediate dentin sealing (IDS) is discussed as a protocol applicable to both direct and indirect restorations, using a primer-and-adhesive sequence that seals dentinal tubules at the time of preparation. For indirect cases, this is especially critical because temporization leaves tubules exposed and vulnerable to contamination over time, which can contribute to post-operative sensitivity and pulpal inflammation.
When rating the factors most responsible for composite failure — isolation, adhesive protocols, curing protocols, and finishing procedures — all four were rated at the highest level of clinical importance. Contamination from saliva at any stage before complete curing was identified as an immediate cause for restarting the restoration entirely, reinforcing the case for rubber dam use as a non-negotiable standard rather than an optional step.
Single-manufacturer restorative systems are favored for clinical troubleshooting as much as for material compatibility. When adhesive and restorative material come from the same company, failures can be investigated with a clear chain of accountability — whereas mixing products from different manufacturers introduces liability disputes between companies and makes root-cause analysis difficult for the clinician.
Occlusal analysis was identified as the single most critical variable in long-term composite success, rated above all other technical factors. Checking occlusion with the patient seated upright rather than reclined was emphasized as essential, because the reclined position does not replicate functional joint position and leads to inaccurate articulation readings that result in premature contacts and restoration failure over time.
Perfect for: General dentists looking to refine their direct composite workflow, dental residents developing material selection frameworks, and cosmetic dentistry practitioners seeking a biomimetic, occlusion-focused approach to anterior and posterior restorations.
If you have ever questioned whether your composite failures are a material problem or a technique problem, this episode will reframe how you think about every step of the process.
