Bioceramic putty versus MTA for pulpotomy of second primary molars with 3D-printed resin or stainless steel crowns
Official title: Effectiveness of Bioceramic Calcium Silicate-based Pulpotomy Medicament on Primary Molars Restored With 3d Printed Resin Crowns (a Randomized Controlled Clinical Trial)
Run by Alexandria University · NCT07344038 · Data updated 2026-11-12
This trial will test whether bioceramic putty or MTA works better for pulpotomy in healthy, cooperative children aged 5–7 with deep carious second primary molars that will be covered with either 3D-printed resin crowns or stainless steel crowns.

Is this trial a fit for you?
✓Likely a good fit
Healthy, cooperative children aged 5–7 with vital, deeply carious second primary molars requiring pulpotomy and full-coverage restoration are ideal candidates.
✕Probably not a fit
Children with spontaneous pain, tooth mobility, excessive bleeding after pulp amputation, radiographic signs of root resorption or periapical pathology, prior treatment of the tooth, or special healthcare needs are unlikely to benefit from inclusion.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Children aged 5–7 with deep carious second primary molars that reach the pulp will have caries removed and pulpotomy performed after achieving hemostasis. The exposed pulp chamber will be covered with either MTA or EndoSequence bioceramic putty, then a resin-modified glass ionomer will be placed and the tooth prepared for full coverage. Teeth will receive either conventional stainless steel crowns or 3D-printed resin crowns as the final restoration. Clinical and radiographic outcomes will be monitored during follow-up visits to compare success between the materials and crown types.
Why it matters
Potential benefit: If successful, this could offer a more biocompatible pulpotomy material and a tooth-colored 3D-printed crown option for primary molars.
How similar studies have gone: MTA has strong clinical evidence for pulpotomy success, while bioceramic putties and 3D-printed resin crowns have promising but more limited and shorter-term data.
