Pulp Disease, Dental | Other: Primary molars pulpotomies with NeoMTA Other: Primary molar pulpotomies with NeoPUTTY | Not Applicable |
This single-site, double-blinded (participants and evaluators) randomized clinical trial with parallel groups will be conducted at the Division of Dentistry, Montreal Children's Hospital. Healthy children aged between 3 and 10 years undergoing dental rehabilitation under general anesthesia who have deep caries lesions approximating or reaching the pulp without any signs or symptoms of pulpal degeneration in one or more primary molars will be invited to participate in this study. All participants will be randomly assigned (1:1 ratio) into two groups: i) pulpotomy with NeoMTA; and ii) pulpotomy with NeoPutty. Follow-up visits at 1, 6, 12 and 24 months will be conducted to assess the clinical and radiographic outcomes.
The sample size calculation was done using G*Power 3.1.9.4 software (Heinrich-Heine-Universität Düsseldorf, Düsseldorf, Germany). In a recent study conducted by our research team, the 24-month success rates of NeoMTA pulpotomy in primary molars was 98% (manuscript in preparation for submission). To account for a desired accuracy of 20%, a significance level of 5%, and a safety margin of 20% to compensate for patient dropouts, a minimum sample size of 47 teeth in each group will be required.
Trained clinical staff f will perform all primary molar pulpotomies following a standardized protocol doe each pulp medication used (NeoMTA or NeoPUTTY).
A baseline questionnaire will be filled by caregivers to assess children's sociodemographic characteristics. At each follow-up visit, standardized clinical and radiographic will be performed by trained dentists.
The post-operative clinical success will be considered as a retained tooth that is void of signs and symptoms of infection such as pain on percussion, mobility, presence of a fistula, or an abscess. Radiographic success will be determined by the lack of pathologic changes such as internal or external root resorption, or a periradicular pathosis. The extraction of the tooth due to signs and symptoms of infection will be considered as a failure.

Active Comparator: NeoMTA
Trained dentists will perform the primary molar pulpotomy following a standardized protocol. After amputation of the coronal pulp, the pulp chamber will be filled with NeoMTA 2. Tooth will be then restored with an appropriately sized stainless steel crown cemented with a glass ionomer cement at the same visit. Follow-up visits will be scheduled at 1, 6, 12 and 24 months after the procedure to assess the success rate of primary molars pulpotomy.

Other: Primary molars pulpotomies with NeoMTA
Primary molar pulpotomies will be performed by trained dentists using NeoMTA, a bioactive material containing calcium silicate known for its bio-active and bone forming potential. Follow-up visits at 1, 6, 12 and 24 months will be conducted to assess success rate, and clinical and radiographic outcomes |
Experimental: NeoPUTTY
Trained dentists will perform the primary molar pulpotomy following a standardized protocol. After amputation of the coronal pulp, the pulp chamber will be filled with NeoPUTTY. Tooth will be then restored with an appropriately sized stainless steel crown cemented with a glass ionomer cement at the same visit. Follow-up visits will be scheduled at 1, 6, 12 and 24 months after the procedure to assess the success rate of primary molars pulpotomy.

Other: Primary molar pulpotomies with NeoPUTTY
Primary molar pulpotomies will be performed by trained dentists using NeoPUTTY, a ready to use bioactive material containing calcium silicate. Follow-up visits at 1, 6, 12 and 24 months will be conducted to assess success rate, and clinical and radiographic outcomes |
