Ep. 791 - The Latest in Composite Dentistry: Universal Composites, Bonding & Clinical Pearls

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.
