Discover how Denstply Sirona’s trusted range of endodontic solutions can provide you and your patients with complete peace of mind by delivering consistent, reliable results when used together as part of your endodontic workflow.
Endodontic success is built step by step, and while shaping, cleaning, and obturation are fundamental, studies suggest that a sound coronal seal is of paramount importance to the overall success of root canal treatment.1
Although temporary restorations can provide an adequate seal when used correctly, a properly cleaned, shaped, and obturated tooth should be permanently restored as soon as possible to increase the longevity of the treated tooth and reduce complications.
Why Coronal Seal Matters
Once access is gained, the pulp chamber becomes a potential pathway for bacterial ingress, and coronal leakage can occur rapidly if sealing is delayed or inadequate. Marginal gaps, temporary restorations, or materials that do not bond predictably can all allow contamination to reach the canal system, increasing the risk of post-treatment disease.
In fact, one key study reported that 48.6% of root-canal-treated teeth with a poor coronal seal showed signs of infection – a dramatic decline in success when compared to teeth with a good coronal restoration, of which 80% showed healthy apices.
A predictable coronal seal should do the following:
- Minimise bacterial penetration and microleakage.
- Protect the obturation and canal system.
- Support periapical healing.
- Enhance long-term restorative success.
For these reasons, coronal sealing should be considered an integral part of the endodontic workflow.
Improve Coronal Seal With Proven Solutions From Dentsply Sirona
Choosing the right products is the first step towards a successful coronal seal. Dentsply Sirona supports a system-based approach to endodontic treatment, offering integrated solutions designed to work together seamlessly from access through to final restoration. By aligning shaping, obturation and restoration, clinicians can reduce complexity and improve predictability.
Shaping With WaveOne® Gold
Predictable shaping creates the ideal foundation for effective irrigation, obturation and, critically, a durable coronal seal. Boasting ten years of clinical success, Dentsply Sirona’s WaveOne Gold single-file reciprocating system is trusted by clinicians worldwide thanks to its consistent, reliable results.
- Enhanced Flexibility: Enable efficient shaping while respecting canal anatomy thanks to WaveOne Gold’s gold heat-treated alloy, designed to increase safety, flexibility, and resistance to cyclic fatigue.
- Predictable Outcomes: Discover WaveOne Gold’s streamlined shaping technique that delivers consistent, reliable results.
- Choice Of Sizes: Choose between four file sizes (Small, Primary, Medium, and Large) and three working lengths (21, 25, and 31mm) to accommodate more canal anatomies.
Obturating With Conform Fit™ And AH Plus®
A strong coronal seal depends on what lies beneath it. Dentsply Sirona’s obturation solutions are designed to provide excellent adaptation, dimensional stability, and long-term sealing ability.
Precisely matched to the WaveOne Gold system, Conform Fit gutta percha points are designed to support efficient, predictable cone selection, and a reliable fit within the prepared shape. And when paired with AH Plus – the 30-year-established gold-standard epoxy resin sealer – you can trust that your obturation foundation is built for success.
By helping to minimise gaps and limit potential pathways for bacterial ingress, these materials work together to form a coordinated system that protects against reinfection, allowing you to confidently seal the tooth from apex to crown.
Sealing with SDR® flow+
Once obturation is complete, immediate and effective coronal sealing is essential for long-term clinical success. For 15 years, SDR has been a trusted solution for clinicians seeking a predictable, durable coronal seal following endodontic treatment, with SDR flow+ being an ideal choice of bulk fill flowable composite.
Engineered to significantly reduce polymerisation stress – one of the key contributors to marginal breakdown and microleakage – SDR flow+ helps maintain the integrity of the adhesive interface to support a tight, long-lasting seal over the pulp chamber and canal orifices.
- Low Polymerisation Stress: Reduce gap formation, minimise stress build-up, and increase workflow efficiency with SDR flow+’s excellent adaptation, even in 4mm bulk placement.
- Excellent Flow And Marginal Integrity: Protect root fillings by ensuring potential pathways for bacteria are sealed with SDR flow+’s self-levelling flowable formula, helping you deliver faster restorations with improved marginal integrity and durability.
- High Radiopacity: Easily perform post-operative evaluations thanks to SDR flow+’s high radiopacity, for simplified restoration monitoring over time.
- Suitable For A Wide Range Of Indications: Discover the clinical versatility of SDR flow+, suitable for use in Class I, III, V, post-endodontic treatment, primary posterior dentition, pit and fissure sealing, and core build-up.
Evidence increasingly supports the placement of an immediate definitive coronal seal following obturation, with delays shown to expose the canal system to contamination, undermining treatment outcomes. SDR enables clinicians to place a reliable core build-up efficiently, even prior to full cuspal coverage, helping safeguard the tooth during the restorative phase.
Used within an appropriate adhesive protocol and followed by a definitive restoration, SDR flow+ acts as a stress-absorbing foundation that protects both the tooth and the endodontic work beneath.
The Importance Of A Tried, Tested, And Trusted Endodontic Workflow
In dentistry, products that stand the test of time do so by delivering consistent performance in everyday clinical practice. When used together, Dentsply Sirona’s innovative, evidence-based WaveOne Gold, AH Plus, and SDR ranges deliver reliable results by supporting a workflow focused on:
- Efficient and conservative canal shaping.
- Predictable obturation.
- Immediate, durable coronal sealing.
Coronal seal is a cornerstone of endodontic success. By choosing proven, system based solutions, clinicians can protect their work, reduce the risk of reinfection, and deliver predictable long term outcomes for their patients.
Using Dentsply Sirona’s WaveOne Gold, AH Plus and SDR flow+ together can transform your endodontic workflow by helping to ensure that every root canal treatment is sealed for success from the root to crown.
If you’re looking to optimise your endodontic workflow by combining premium products throughout for less, Dentsply Sirona’s Coronal Seal Kit is a great place to start. Complete with the full WaveOne Gold file sequence plus SDR flow+ compules, you can reap their combined benefits within a single handy kit, while also making each restoration cheaper and saving your practice money.
