Publication Open Access Tooth discoloration effects of calcium silicate based barrier materials used in revascularization and treatment with internal bleaching(2017-12-01T00:00:00Z) Akbulut, Makbule Bilge; Terlemez, Arslan; Akman, Melek; Buyukerkmen, Begum; Guneser, Mehmet Burak; Eldeniz, Ayce Unverdi; GÜNEŞER, MEHMET BURAKBackground/purpose: Usage of barrier materials is an important step in revascularization procedure. One of the undesired properties of these barrier materials is to cause coronal tooth discoloration. The aim of this in vitro study was to evaluate the tooth discoloration induced by ProRoot MTA (PMTA), Biodentine, and MM-MTA, as well as the efficacy of internal bleaching on this discoloration.Publication Open Access Antibacterial effect of chlorhexidine-cetrimide combination, Salvia officinalis plant extract and octenidine in comparison with conventional endodontic irrigants(2016-10-01) Guneser, MEHMET BURAK; Akbulut, Makbule Bilge; Eldeniz, Ayce Unverdi; GÜNEŞER, MEHMET BURAKThe aim of the present study was to compare the antimicrobial effect of sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX), a CHX/cetrimide solution (CHX+CTR), octenidine hydrochloride (OCT) and Salvia officinalis plant extract against Enterococcus faecalis. Seventy decoronated single-rooted human teeth were infected and divided into 6 test (n=10) and 2 control groups (n=5) (negative, sterile samples and positive, infected samples). Following irrigants were then applied to test groups: 2.5% NaOCl, 5.25% NaOCl, CHX, CHX+CTR, S. officinalis extract and OCT. The dentin chips were obtained from inner root canal walls and analyzed by counting the number of colony forming units (CFU). The 2.5% NaOCl, 5.25% NaOCl, CHX and OCT groups presented no bacterial growth (CFU=0). S. officinalis and CHX+CTR groups reduced the number of E. faecalis cells but could not eliminate all. OCT may have potential as an endodontic irrigant in treatment of infected root canals.
