Abstract Calcium enriched mixture (CEM) cement has been recently invented by the last author. It is composed of calcium oxide, phosphate, silicate and sulphate; however, it a different chemical composition to mineral trioxide aggregate (MTA). The purpose this ex vivo study was investigate cytotoxicity CEM cement, compare with intermediate restorative material (IRM) MTA. materials were tested in fresh set states on L929 fibroblasts assess their cytotoxicity. cell viability responses evaluated...
This equivalence, randomized, clinical trial aimed to compare the postoperative pain of root canal therapy (RCT) with pulpotomy mineral trioxide aggregate (PMTA) or calcium-enriched mixture (PCEM) in permanent mature teeth. In seven academic centers, 550 cariously exposed pulps were included and randomly allocated into PMTA ( n = 188), PCEM 194), RCT 168) arms. Preoperative “Pain Intensity” (PI) on Numerical Rating Scale PIs until day 7 recorded. Patients’ demographic...
Abstract The purpose of this study was to determine the effectiveness MTAD as final irrigant remove smear layer, compared with that 17% EDTA, both following root canal irrigation 5.25% sodium hypochlorite (NaOCl). Fifty‐five extracted maxillary and mandibular single‐rooted human teeth were prepared by a crown‐down technique using rotary 0.04 0.06 taper nickel‐titanium files. used intracanal irrigant. canals then treated 5 mL one solutions rinse: hypochlorite, EDTA or MTAD. presence absence...
Introduction: Antimicrobial photodynamic therapy (aPDT) as a supplement to the conventional root canal preparation has shown promising results. Previous studies have adopted various combinations of light sources and PSs, well different parameters, PS concentrations, methods for biofilm cultivation, which makes it difficult compare disinfection efficacy PDT protocols. The aim present study was three Photosensitizers (Toluidine blue, Methylene Curcumin) in using LED against Enterococcus...
The purpose of this study was to compare substance P (SP) and calcitonin gene-related peptide (CGRP) expression in pulp tissue with clinically diagnosed symptomatic asymptomatic irreversible pulpitis. Healthy pulps acted as controls. Five normal 40 pulpitis (20 20 asymptomatic) were obtained from 45 different patients. SP CGRP determined by competition binding assays using enzyme immunoassay. anova Mann-Whitney tests used ascertain if there statistically significant differences between the...
Endodontic sealers usually come in contact with adjacent tissues and their biocompatibility is key a successful treatment. The purpose of this study was to assess the cytotoxicity three resin-based sealers, namely AH Plus, EndoREZ, Epiphany set fresh states on an L929 cell line.In vitro experimental study, materials were mixed according manufacturers' instructions, divided into two groups, set. elutes prepared separately incubated fibroblasts for 1 hour, 24 hours, 72 hours. Pulp Canal Sealer...
Abstract Failure to achieve complete anaesthesia of teeth with acutely inflamed pulps is a well‐known clinical symptom. In this study, we compared the quality in intact and mandibular by using an electric pulp tester. Thirty patients lower teeth, which had spontaneous or night pain, were selected; two healthy same quadrant used as control teeth. Electric testing thermal tests made on each tooth. Teeth then anaesthetised inferior alveolar nerve block repeated Significant differences found...
Gutta-percha (GP), is a neutral and non-toxic material. The aim of this animal study was to compare the biocompatibility nanosilver coated GP (NS-GP) with conventional in subcutaneous tissues rat model.Conventional NS-GP were subcutaneously implanted backs 20 male Wistar rats (n=10). A control assigned for each trial period. Ten animals sacrificed after 7 30 days light microscopic evaluation tissue reaction (n=20) accomplished. Mann-Whitney U, Wilcoxon Signed Ranks, Fisher Exact, McNemar...
Objectives: Different chelators may be used during root canal treatment, offering various advantages including lubricant effect inside the and smear layer removal. However, chelator residues in narrow canals can lead to apical microleakage. The aim of this in-vitro study was compare microleakage following use three via fluid filtration method instrumented with ProTaper rotary system.Methods: Sixty-eight distobuccal maxillary first molars were randomly divided into six groups four...
Objectives Adequate knowledge about canal anatomy is necessary for clinicians to prevent any damage the periodontium. The aim of this study was evaluate and apical complexities mandibular first second premolars in an Iranian population. Methods One-hundred (n=50) were collected. After access cavity preparation, 2% methylene blue injected into canals, they sealed with Coltosol nail varnish. Next, demineralization clearing 5% nitric acid methyl salicylate performed. Apical morphology including...
Mineral trioxide aggregate (MTA) is extensively used in endodontics. However, it has limitations such as long setting time, low compressive strength and poor handling properties. Our study aimed to compare the time surface microhardness of MTA fluoride-doped (FMTA) using gel-like polymer (GLP) or distilled water (DW) liquid.An MTA-like cement was prepared by mixing Portland cement, bismuth oxide gypsum (75%, 20% 5%, respectively). FMTA (1% 5%) made substituting 1% 5% powder with fluoride....
