About this study

Official title: A Split-mouth Trial Comparing Biodentine and Calcium Hydroxide in the Indirect Pulp Treatment on Primary Teeth

Objective: The study's main purpose is to evaluate and compare the clinical and radiographic outcomes of Biodentine and a light-activated calcium hydroxide based-liner (Ultra-Blend plus®) as indirect pulp treatment (IPT) liners, over the dentin-pulp complex of vital primary molars with carious lesions approaching the pulp. Study design: 80 four-to-eight year-old patients were enrolled from a Mexican University Pediatric Dentistry Clinic. A split-mouth design trial is being conducted in order to compare both IPT interventions on 160 bilateral primary teeth, without signs or symptoms of irreversibly inflamed or degenerative pulp tissue. Teeth were treated and restored with a preformed crown in a single session, and then closely followed-up for 1, 3, 6, 12, 18, and 24 months.

Read the detailed description

A Split-mouth clinical trial was the design selected. Clinical Procedures: IPT procedures were carried out by three pediatric dentistry residents (E.K.C.G., R.A.V.V., and J.M.A.R.), previously trained in the clinical setting with a pilot sample of 10 similar child patients each. Study participants received local anesthesia and rubber dam isolation, which was disinfected, followed by the remove of the carious peripheral dentin with high speed tungsten-carbide bur # 3, and air-water spray. Then, the soft dentin layer was carefully removed with a sharply-edged sterilized hand excavator, based on tactile and visual standards, leaving only the hard dentin adjacent to the pulp ceiling. The cavity was thoroughly rinsed only with water and then dried with sterilized cotton pellets; no other special disinfection protocol was applied. The next step consisted in the placement of the correspondent liner over the remanent carious dentin layer, following the manufacturers' instructions, and according to the randomly assignment scheme previously described. In the case of the control group, the liner was cured undr 20 seconds of light exposure. All treated molar were restored with stainless steel preformed crowns (3M ESPE) cemented with glass ionomer (Ketac-Cem, 3M ESPE). One week later, the same procedure was repeated in the opposite tooth with the contrary IPT agent.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Indirect Pulp Treatment with Bioactive Dentin SubstituteProcedure or surgery

    Also called Biodentine

    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.

  • Indirect Pulp treatment with Calcium hydroxideProcedure or surgery

    Also called Ultra-Blend plus

    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 Ultra-Blend plus, and a hermetic restoration to provide a seal against microleakage, without the necessity to reenter for removing the residual caries.

Study groups in NCT02799927
Study groupRoleWhat they receive
BiodentineExperimentalBiodentine (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.
Receives: Procedure: Indirect Pulp Treatment with Bioactive Dentin Substitute
Ultra-Blend plus (Calcium hydroxide)Active comparatorUltra-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 .

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain. Binary variable (present/absent).

    Pain is assessed through interrogatory. It is a binary variable (pain present or pain absent)

    Measured: 2 years

Secondary outcomes (5)
  1. Sensitivity to percussion. Binary variable (present/absent).

    Treated tooth is softly hit with a dental handle mirror. Sensitivity is recorded as a binary variable (present/absent).

    Measured: 2 years

  2. Abnormal tooth mobility. Binary variable (present/absent).

    This variable is measured by handling the treated tooth with two fingers. It is a binary variable (present/absent).

    Measured: 2 years

  3. Soft tissues inflammation. Binary variable (present/absent).

    This feature is assessed through visual examination of surrounding soft gingival tissues (texture, color, size). It is a binary variable(present/absent) .

    Measured: 2 years

  4. Periradicular lesions. Binary variable (present/absent).

    These lesions are observed through radiographic examination. They appear as radiolucencies around the tooth's root (s). It is a binary variable (present/absent)

    Measured: 2 years

  5. Sensitivity to palpation. Binary variable (present/absent).

    Treated tooth is softly pressed with a finger. Sensitivity is recorded as a binary variable (present/absent).

    Measured: 2 years
