Bioceramic Putty Versus MTA in Pulpotomized Primary Teeth to be Covered With 3D Printed Resin Crowns Versus Stainless Steel Crown
Effectiveness of Bioceramic Calcium Silicate-based Pulpotomy Medicament on Primary Molars Restored With 3d Printed Resin Crowns (a Randomized Controlled Clinical Trial)
Alexandria University
60 participants
Jan 20, 2026
INTERVENTIONAL
Conditions
Summary
children aged 5 to 7 years with deep carious second primary molars that require vital pulp therapy will be treated using either MTA or bioceramic putty, then will be fully covered using either stainless steel crowns or 3D printed resin crowns.
Eligibility
Inclusion Criteria5
- Deep carious second primary molars with:
- Vital pulp confirmed by absence of clinical and/or radiographic signs of necorosis or infection.
- Signs of reversible pulpitis. 10
- Require full coverage restorations
- Cooperative children (Frankl 3 or 4 behavior rating scale)
Exclusion Criteria1
- History of spontaneous pain. 2. Tooth mobility. 3. Excessive bleeding from radicular stumps after coronal pulp amputation. 4. Radiographic evidence of pathological root resorption, inter-radicular bone loss, periapical pathology, or canal calcifications. 5. Previous dental treatment of the involved molar. 6. Children with special healthcare needs.

Interventions
* Profound local anesthesia and rubber dam isolation will be applied. * Carious tissue will be completely removed using diamond burs until pulp exposure and deroofing. * Coronal pulp will be removed with a sharp excavator. * Hemostasis will be achieved with a saline-moistened cotton pellet for 5 minutes. * Bioceramic putty applied directly from the manufacturer's syringe, then adapted gently with a moist cotton pellet.
* Profound local anesthesia and rubber dam isolation will be applied. * Carious tissue will be completely removed using diamond burs until pulp exposure and deroofing. * Coronal pulp will be removed with a sharp excavator. * Hemostasis will be achieved with a saline-moistened cotton pellet for 5 minutes. * The MTA powder will be mixed with the liquid to a putty consistency and applied with an amalgam carrier.
* Occlusal reduction of 1.0-1.5 mm using a flame-shaped diamond bur. * Interproximal slicing to enable passive crown placement. * Crown size selection based on best fit. * Cementation using RMGIC. * Excess cement will be removed.
* Tooth preparation: 1 mm axial reduction with a chamfer finish line using tapered diamond stone with round end (Mani TR-12) for buccal, lingual, mesial, and distal walls. * One and half - 2 mm occlusal reduction. * Digital impressions using IOS scanning, including occlusion and antagonist. * 3D printed resin crowns will be designed using the Exocad software (Exocad Rigeka 3.1) to have a uniform thickness on all surfaces (average 1 mm), including occlusal, buccal, lingual, and proximal surfaces. After reviewing each design, it will be exported as a high-resolution STL file (standard tessellation language) to be outsourced and 3D printed. * BEGO DLP printer will be utilized to print the crowns using VarseoSmile Trinique resin via digital light processing (DLP) technique. * After printing, the platform will be removed from the 3D printer and placed on a paper towel with the printed crowns facing upward. * The printed crowns will be separated from the platform and rinsed tw
