“…Acid-etching of enamel creates surface micro-pores by dissolving calcium and phosphate ions, which re-precipitate as MCPM following enamel conditioning with PA of concentrations exceeding 27% (17). The volume and low solubility of calcium phosphate crystallites encourage their stagnation and resistance to water irrigation, which can adversely affect the bond strength (18). Since the etchant paste is already made of MCPM, more crystallites precipitation is expected to take place, hence impeding the complete resin infiltration into the micro-pores and yielding lower bond strength (5).…”

“…The OH À (3720-2600 cm À1 ) and PO 3À 4 (1180-920 cm À1 ) regions were analysed; these are associated with water and mineralized dentine, enabling examination of alterations connected to the loss of collagen and demineralization of dentine (Eliades et al 2013, Feitosa et al 2013.

“…The influence of storage media on dentine surfaces is important. Therefore, it would be interesting to evaluate the -OH À and ÀPO 3À 4 parameters, which are related to a variety of the dentine components (Eliades et al 2013, Feitosa et al 2013, representing the water and mineralized dentine levels.…”

Objectives This study aimed to incorporate hydroxyapatite nanoparticles (nHA) or amorphous calcium phosphate nanoparticles (nACP) into a self-etch primer (SEP) to develop a simplified orthodontic bonding system with remineralizing and enamel preserving properties. Materials and Methods nHA and nACP were incorporated into a commercial SEP (Transbond™ plus) in 7% weight ratio and compared with the plain SEP as a control. Shear bond strengths (SBS), enamel damage, and adhesive remnant index (ARI) scores were evaluated at 24 h and post 5000 thermocycling. Field-emission scanning electron microscope (FESEM) was used to inspect the distribution of the nanoparticles in the experimental SEPs and evaluate the enamel surface integrity both before bracket bonding and post bracket debonding. Phase determination and remineralizing capability of the modified SEP were characterized by X-ray diffraction and Raman spectroscopy, respectively. Results The addition of nHA or nACP to the SEP significantly reduced the SBS, ARI, and enamel damage (p < 0.05) as compared to the control SEP; however, only nHA-SEP survived the thermocycling protocol and yielded acceptable SBS (13.38 MPa). Enamel remineralizing ability of the developed nHA-SEP was confirmed by both FESEM images and Raman phosphate map. Conclusions Incorporating nHA into SEP resulted in clinically acceptable bond strengths with remineralizing ability. Clinical relevance The newly developed nHA-SEP has unprecedented ability to simultaneously etch, prime, and remineralize the enamel in a single step leaving immaculate enamel surface with the potential of saving cost and time at the post-debonding step.
