Bioceramics vs. Traditional Techniques: Why the Topic Is Back in the Spotlight
In endodontics, root canal obturation is not merely a "final step": it determines the long-term sealing of the root canal system, the stability of the outcome, and, when necessary, the possibility of retreatment. In recent years, bioceramic cements (often calcium silicate-based) have become common in daily practice, challenging protocols historically dominated by gutta-percha combined with epoxy resin or zinc oxide-eugenol cements.
Should habits be changed? In this article, we pragmatically review the situation, without sensationalism, to help you choose the right strategy for each clinical case.
What does โbioceramicโ mean in endodontics?
The term โbioceramicsโ refers to materials whose chemistry aims to be tissue-compatible and to interact favorably with the humid environment of the canal. Current bioceramic sealers are generally hydrophilic, leverage dentin moisture for setting, and may exhibit some bioactivity (apatite formation on the surface, initially high pH depending on the formulation).
In practice, this often translates to simpler handling, potentially better moisture tolerance than with certain more sensitive materials, and a sealing logic that relies on the cement's chemistry as much as on mechanical compaction.
Review of traditional techniques: What has proven effective
"Traditional" approaches typically rely on gutta-percha as the main material, combined with an endodontic cement (epoxy resin, zinc oxide-eugenol, etc.). Obturation can be performed using a single cone, lateral condensation, or warm vertical compaction.
These techniques benefit from decades of clinical experience, well-codified protocols, and extensive literature. They remain a benchmark, particularly because they are reproducible when canal shaping, irrigation, and drying are mastered, and because retreatment is generally well-defined for most technique/material combinations.
Clinical comparison: What do the available data indicate?
The important point to remember is this: in comparative clinical studies, bioceramic sealers generally show similar success and survival rates to traditional techniques when used with a consistent protocol.
In other words, bioceramics are not a "magic wand" that compensates for insufficient disinfection or imprecise shaping, but they can be effectively integrated into a high-quality operational chain. Several randomized controlled trials and systematic reviews report non-inferiority or equivalence in terms of medium-term success, and comparable levels of postoperative pain depending on clinical situations and methodologies.
Regarding sealing, some experimental data suggest the benefit of compaction techniques (especially warm compaction) to optimize adaptation, even with bioceramic sealers, but the final outcome strongly depends on operational control and canal morphology.
Chairside implications: How to choose without dogma
To choose between bioceramics and a more traditional approach, three questions are worth asking. First, what is your obturation strategy: single cone/hydraulic, warm technique, or a combination? Second, what is your primary objective: simplicity and standardization, management of a complex case (irregular canal, difficult anatomy), or anticipation of retreatment? Finally, what is your level of mastery of the complete protocol, from irrigation to drying, and working length control?
In a standardization logic, bioceramic sealers are often chosen for their behavior in a humid environment and their "hydraulic" approach with a well-fitted master cone. In a logic of optimizing 3D adaptation, warm techniques remain relevant but require strict control to avoid overpressures, voids, and extrusions.
Finally, if retrievability is a major criterion (prosthetic context, uncertain prognosis, risk of redo), it is prudent to consider the literature and your experience: some materials are easier to retrieve than others, and results may vary depending on the formulation and technique.
Focus: Neo Sealer, a bioceramic sealer available at Endoboutik
If you wish to explore a solution from the bioceramic family, you can consult Neo Sealer (Flo ZA by Avalon) on our website: https://endoboutik.com/products/neo-selaer-flo-za-by-avalon.
The idea is not to "replace" a protocol that already works, but to evaluate a material based on your indications, your obturation technique, and your clinical objectives (seal, reproducibility, operative comfort, anticipation of possible retreatment). As always, the quality of disinfection and adherence to operative steps remain the main determinants of the outcome.
Questions and Answers
- What is a bioceramic cement in endodontics?
A bioceramic cement is an endodontic cement, based on calcium silicate or MTA, designed to be compatible with tissues and function in a humid environment. It is used in conjunction with a gutta-percha cone to obturate the root canal system.
- Are bioceramics more effective than traditional techniques?
Available clinical data most often show comparable results (equivalence or non-inferiority) when the protocol is well executed. The material does not replace the fundamentals: shaping, irrigation, and working length control.
- Can a bioceramic cement be used with a warm technique?
Yes, some practitioners combine bioceramics with warm techniques. The key point is to master placement and avoid overpressures. The choice depends on your protocol and the canal anatomy. However, for us, bioceramics are used more as an obturation material than as a simple sealing cement.
- Is retreatment more difficult with a bioceramic?
Disobturation can vary depending on the formulations and the obturation technique. It is reasonable to anticipate this question before standardizing a protocol, especially for teeth with an uncertain prosthetic prognosis.
- Does bioceramics reduce postoperative pain?
Clinical reviews generally report similar levels of postoperative pain between bioceramic cements and resin-based cements, depending on studies and contexts. Pain also depends on multiple operative factors.
- Where can I find a bioceramic cement like Neo Sealer?
Neo Sealer is available on Endoboutik: https://endoboutik.com/products/neo-selaer-flo-za-by-avalon. To choose, prioritize a critical reading of indications, your technique, and clinical objectives.
