Methods: 98 patients participated in this study. Inclusion criteria were as follow: existence of at least one tooth with deep caries, no evidence of irreversible pulpitis and PDL widening, and presence of a radiopaque zone at the pulpal wall. Participants were randomly divided into 4 groups: Group 1(Control): No liner applied, Group 2: Calcium Hydroxide, Group 3: MTA, Group 4: CEM cement. After baseline evaluation of response of the involved tooth to cold, hot, percussion and pressure, a cavity was prepared and caries excavated completely from the periphery of the cavity but it was remained on the pulpal floor or the axial wall. The liner was applied; the cavity was conditioned with polyacrylic acid, and restored with posterior glass ionomer (Fuji 9 plus, GC Co., USA). Clinical and radiographic evaluation were done at specific times until 12 months and x-rays were taken after 2,6 and 12 months.
Results: Experience of sensitivity to cold in groups were as follow: group1:3, group2:7, group3:1, group4:0. 2cases in group 1 and 2 cases in group 2 needed RCT.
Conclusions: One year results of this clinical study indicated that all the materials application of biomaterials (MTA and CEM) could be promising in deep caries treatment.
