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

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.
