Description
Inclusion criteria:
- At least one restorable first or second primary molar in each side of the mouth, affected by an occlusal cavitated active caries lesion in deep dentin.
- Cooperative patients.
- Participants were included in the trial after parental acceptance through a signed informed consent.
Exclusion criteria:
- Molars with mobility, spontaneous pain or fistula, and radiographic findings such as a carious lesion with no evidence of residual dentin over the pulp chamber or manifest pulp exposition.
- Normally internal root resorption or physiological root resorption less than 1/3.
- Presence of periradicular/furcal radiolucent lesions.
- Occurrence of a carious pulp exposure and bleeding during the operative procedure.

Experimental: Biodentine
Biodentine (Septodont, Saint-Maur-des-Fosses, France) has been recently introduced and marketed as a bioactive dentin substitute. The Biodentine powder contains tricalcium silicate, dicalcium silicate and calcium oxide, while its liquid consists of calcium chloride and a carboxylate-based hydrosoluble polymer (water-reducing agent). After local anesthesia and rubber dam isolation, carious peripheral dentin is eliminated with a high speed tungsten-carbide bur # 3, and air-water spray. Then, the cavity's floor soft dentin layer is carefully removed with a sharply-edged sterilized hand excavator, leaving only the hard dentin adjacent to the pulp ceiling. The cavity is thoroughly rinsed only with water and dried with sterilized cotton pellets. The next step consists in the preparation of Biodentine liner (a mix of powder and liquid), following the manufacturers' instructions, and its placement over the remanent carious dentin layer. |
The indirect pulp treatment (IPT), with Biodentine is a vital pulp procedure for dep cariously primary teeth without carious exposure, involving the removal of the softened, humid and infected dentin layer, leaving intact intentionally the deepest layer of the dentin-pulp complex, followed by the placement of Biodentine and a hermetic restoration to provide a seal against microleakage, without the necessity to reenter for removing the residual caries.

Active Comparator: Ultra-Blend plus (Calcium hydroxide)
Ultra-Blend plus® (Ultradent Products Inc., South Jordan, UT, USA). This material is a light-activated calcium hydroxide based-liner. Calcium hydroxide has demonstrated to reduce and promote immediate deactivation of the residual microorganisms after IPT. After local anesthesia and rubber dam isolation, carious peripheral dentin is eliminated with a high speed tungsten-carbide bur # 3, and air-water spray. Then, the cavity's floor soft dentin layer is carefully removed with a sharply-edged sterilized hand excavator, leaving only the hard dentin adjacent to the pulp ceiling. The cavity is thoroughly rinsed only with water and dried with sterilized cotton pellets. The next step consists in the placement of Ultra-Blend plus liner over the remanent carious dentin layer, using a dycal metallic applicator. Finally, the liner is cured through light exposure during 20 seconds . |
