“…XRD, Raman, and infrared spectra showed the typical composition of both BC putty and paste: calcium phosphate hydrate, calcium aluminum silicate, tantalum oxide, and zirconium oxide. This result is in agreement with previous studies (Abu Zeid et al, 2018; Alamoudi & Abu Zeid, 2019).…”

“…Since the BCRRM is a pozzolanic material containing calcium hydroxide (Ca[OH] 2 ) (Abu Zeid et al, 2018), the surface pigmentation formed on BC putty and paste surface after CHX treatment was proposed initially to be a paracholoraniline (PCA) (Barbin et al, 2008). Yet, XRD analysis failed to detect PCA, but, it determined the presence of nitrogen‐rich phases including diaminomaleonitrile (C 4 H 4 N 4 ) and 3‐azido‐1,2,4‐triazole (C 2 H 2 N 6 ) on the BC putty surface and hydrazinium 5‐aminotetrazole (N 2 H 5 CN 5 H 2 ) and 1,2,4 triazole (C 2 H 3 N 3 ) on the BC paste surface.…”

“…It induces osteogenic response attributed to its high alkalinity (Edrees, Abu Zeid, Atta, & AlQriqri, 2019). BC‐RRM is a premixed cement composed of calcium silicate, calcium phosphate, calcium hydroxide, and zirconium oxide (Abu Zeid, Mokeem Saleh, Khafagi, & Abou Neel, 2018). It is available as moldable putty or preloaded syringe paste.…”

“…Raman and Fourier transform infrared (FTIR) spectroscopy analysis are well instruments to identify the chemical composition of the material and its reaction to any chemicals (Abu Zeid et al, 2018; Abu Zeid et al, 2019; Alamoudi & Abu Zeid, 2019). X‐ray diffraction (XRD) is the best method to determine the phase composition of the material's surface after any chemical reaction.…”

Morphological and chemical analysis of surface interaction of irrigant‐endosequence root repair material

This study aimed to evaluate the characterization of chemical interaction of root canal irrigants on the surface of EndoSequence root repair materials using spectroscopy analysis. Round discs of putty and paste were obtained and immersed in saline, sodium hypochlorite (NaOCl), or chlorhexidine. On the surface of chlorhexidine treated putty, diffuse red pigmentation was detected by Raman analysis and diffuse black pigmentation having unusual needle-like shaped crystals was detected by scanning electron microscopy. This pigmentation formed from nitrogen-rich compounds detected by Raman, infrared spectroscopy, and X-ray diffraction analysis. Mineral/ amide ratios were increased by NaOCl and significantly decreased by chlorhexidine. Carbonate/phosphate ratios showed no significant changes by NaOCl, while a significant decrease by chlorhexidine. A full half of maximum width Raman of the phosphate band was significantly increased by NaOCl, while decreased by chlorhexidine. In conclusion; nitrogen-rich compounds produced by chlorhexidine altered the surface morphology of the putty without crystallinity reduction. However, NaOCl reduced the organic fillers that affected its binding to phosphate ions. This reaction affects the chemical properties and perfection of root repair material. The clinicians should be aware of different irrigants to be used after repairing the perforation.
