introduction: the purpose of this ex vivo study was to assess the effect of two root-end filling materials against candida (c) albicans . materials and methods: proroot mta and cem cement were compared immediately and 24 h after mixing, in two different concentrations (50 and 100 mg/ml). a total of 50 culture wells were used and divided into experimental (n=10) and control groups (n=5). those w...

introduction: the main goal of this ex vivo study was to assess and compare the cellular and electrophysiological effects of two dental biomaterials, white mineral trioxide aggregate (wmta) and calcium enriched mixture (cem) cement, on neuronal cell excitability and electrical properties. materials and methods: a conventional intracellular current clamp technique was used to study the cellular ...

vital pulp therapy (vpt) of permanent mature teeth is continuously ascertaining to be a more reliable endodontic treatment. the purpose of this case report was to describe successful vpt of a mature mandibular left first molar with concurrent hyperplastic pulpitis, internal root resorption and periradicular periodontitis in a 35-year-old male patient. after complete caries removal and access ca...

statement of problem: calcium hydroxide which is commonly used as an intracanal medicament, changes the ph of dentin and periradicular tissues to an alkaline ph. in some clinical situations, endodontic reparative cements like calcium enriched mixture cement are used after calcium hydroxide therapy. however, the alkaline ph may affect the physical properties of this cement. objectives: this stud...

background: this study was designed to assess the microleakage of glass-ionomer (gi), mineral trioxide aggregate (mta), and calcium-enriched mixture (cem) cement as coronal orifi ce barrier during walking bleaching. materials and methods: in this experimental study, endodontic treatment was done for 70 extracted human incisors without canal calcifi cation, caries, restoration, resorption, or cr...

introduction: the aim of this in vitro study was to determine the sealing ability of orthograde proroot mineral trioxide aggregate (mta) and calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: fifty four extracted single-rooted human teeth were used. the samples were randomly divided into 3 experimental groups. in group a and b, 4 mm of wmta and cem cemen...

Various natural carotenoids seem to be valuable for cancer prevention, and these carotenoids may be more suitable in combinational use, rather than in single use. In fact, we have proven that combinational use of natural carotenoids resulted in significant suppression of liver cancer. Patients of viral hepatitis with cirrhosis were administered with beta-cryptoxanthin-enriched Mandarin orange j...
