AbstractAbstract Dentine hypersensitivity is a clinical condition characterized by sudden and sharp pain arising from stimulation of exposed dentine with cold, heat and mechanical pressure [1]. Hydroxyapatite (HAp) is one of the materials studied and used as active ingredients in dental care products and gets scientific popularity day by day [2-4]. Although pure-HAp has highly biocompability, bioactivity and osteo-conductive properties, its antibacterial resistance is not enough [5-6]. Co-doping of Ag+ in HAp improves its both antibacterial performance [7] and cell viability [8- 9]. And co-doping of Ag+ in HAp has a positive electrostatic effect [8] to plug the dentine tubules. For this purpose, pure and Ag+ ions doped nano-hydroxyapatites, synthesized by the precipitation method [9], which have been used for plugging in dentin tubules also investigated by Scanning Electron Microscopy (SEM), ATR-Fourier Transform Infrared Spectroscopy (ATR-FTIR) for all the degratation studies. Furthermore we tried to observe the effect of degredation on the treated tooth with FTIR. We have a effective occlusion for all types of nHAp and also as can be seen from the FTIR peaks, our samples are at least 90% resistant to degradation.
