Selective Dentine Removal in Primary Teeth

Background There is little information regarding the longevity of the restored tooth, considering the health of the pulp-dentine complex, in children who do not sufficiently cooperate with dental treatment. Aim To evaluate the longevity of primary molar teeth with an occluso-proximal cavity that was treated with the selective removal of carious tissue. Design A total of 150 children were allocated to two parallel groups: group 1 (G1, n = 70, control, Ketac Molar Easymix®, 3M/ESPE, Seefeld, GE) and group 2 (G2, n = 80, test, Maxxion®, FGM, Joinville, BR). The study was double-blinded, and an operator specialized in paediatric dentistry performed the selective removal of soft dentine and the restoration of the cavity with GIC. During the follow-up periods, the teeth were evaluated via periapical radiography by two trained examiners specialized in radiology. Statistical analysis was performed using Stata 11.2 software (StataCorp, Texas, USA) and a survival curve (Kaplan-Meier).
