Hydroxyl ion release ability from mixture of Indonesian White Portland Cements - Bi2O3 - Light Cured Methacrylate Based Resin as a Potential Pulp Capping Material

ABSTRACTIntroduction: The bioactivity property of pulp capping materials is determined by the hydroxyl ion release ability, which may alter environmental pH to become alkaline. Calcium silicate-based are antibacterial, able induce reparative dentin and have a good bacteria-tight seal. poor handling calcium can be overcome adding resin, so will easier handle. Therefore, purpose this study was synthesize mixture Indonesian White Portland Cements - Bi2O3 – UDMA analyzed its ability. Methods: prepared using simple solution method mixed with UDMA. sample’s ability ions measured meter titration test. Results: This showed that had an initial 11.04 increased peak on 168 hours mark, or day seven, 11,77 value 10-2.23 Conclusion: -UDMA alkaline pH, potential used as material.Keywords: Indonesia UDMA, Hydroxyl ion, Release Ability
