Bioceramics vs. Traditional Techniques: What the Clinical Evidence Really Says
In endodontics, canal obturation is not a "final step": it's a procedure that determines sealing, periapical healing, and the practitioner's confidence in their treatment. In recent years, bioceramic cements, particularly calcium silicate-based ones, have emerged as a credible alternative to traditional cements.
But the right question isn't "bioceramic or traditional?" It's "with which technique, in which indications, and with what realistic expectations?"
Clinical Success: Bioceramics are up to standard
The data summarized in the internal article show generally comparable clinical results between bioceramics and established approaches. A recent multicenter randomized controlled trial evaluated two bioceramic formulations from the same family, including a ready-to-use injectable one, and reported similar success rates at 24 months, around 86.6% and 87.7%. Follow-up and secondary criteria, including postoperative pain, showed no significant difference, and no adverse events were reported in the studied groups.
This finding is consistent with a systematic review and meta-analysis compiling comparative clinical studies: no significant difference between premixed bioceramic cements and traditional resin-based cements in terms of survival and success rates. In other words, the strongest argument today is clinical reliability, rather than systematic superiority.
Obturation Technique: The material does not compensate for an average protocol
The comparison "bioceramics versus traditional techniques" quickly becomes a comparison between obturation techniques. Several studies report that warm vertical compaction (WVC) improves obturation quality parameters, particularly penetration into dentinal tubules and sealing. A clinical study comparing, in a WVC strategy, a bioceramic sealer and an epoxy resin sealer described similar success results at two years. This means one very practical thing: adopting a bioceramic sealer does not require changing what already works in your sequence.
Conversely, in vitro studies show more apical leakage with the single cone technique than with WVC, at the observed times. The message is simple: with bioceramics as with traditional methods, shaping, irrigation, control of working length, and the obturation strategy remain crucial.
4-year Follow-up: Calcium silicate vs. zinc-oxide eugenol
Looking at the long term, a randomized clinical trial with four years of follow-up compares a calcium silicate-based obturation combined with a single cone technique to a zinc-oxide eugenol approach with warm vertical compaction.
The results show no significant difference in the overall success rate, nor in elements such as obturation length, voids, or extrusion. Success rates remain high, around 89.6% according to flexible criteria and 83.3% according to strict criteria. This reinforces the idea that bioceramics can be sustainably integrated into demanding practice.
Postoperative Pain: No "zero pain" promise
The analyzed systematic reviews conclude that there is no significant difference between bioceramics and epoxy resins in pain scores (VAS) at early time points. A randomized trial comparing obturation with a single cone technique and WVC also found no significant difference in pain or analgesic use. Bioceramics should therefore be presented as a coherent material choice, not as a marketing argument for discomfort.
Periapical Healing: Clinical interest in the presence of lesions
Several studies report favorable evolution of periapical tissues with calcium silicate-based bioceramic cements. An observational study over 12 months, using a bioceramic cement and hydraulic condensation, describes asymptomatic and functional teeth over the period, with a 100% survival rate and high clinical success, associated with a significant decrease in the periapical index in cases of apical periodontitis.
This type of result supports the idea of particular interest in certain cases with lesions, while recalling that disinfection remains the major factor.
Retreatment: Anticipating variability
In practice, the question of retreatment is essential. A retrospective cohort comparing calcium silicate and epoxy resin found no significant difference in success rates at a median recall of 15 months. However, retrievability can vary depending on the bioceramic formulations, which calls for an informed choice and an adapted operating strategy.

Frequently Asked Questions about Bioceramics:
- Are bioceramics more effective than traditional cements?
The summarized clinical data primarily show comparable effectiveness, with success rates similar to established approaches.
- Should warm vertical compaction be abandoned with a bioceramic sealer?
No. Available clinical results show comparable performance in WVC with bioceramics and with epoxy resin.
- Is the single cone technique with bioceramics a "bad" technique?
It is not a bad technique in principle, but in vitro data report more apical leakage than with WVC, which requires a rigorous protocol.
- Does bioceramics reduce postoperative pain?
The analyzed systematic reviews found no significant difference in pain between bioceramics and epoxy resins at early time points.
- In which cases should bioceramics be prioritized?
In the presence of apical periodontitis, studies report favorable periapical healing with calcium silicate-based cements, in addition to the fundamentals of disinfection.
