Abstract CaCO 3 -pulp composite was prepared via precipitation of calcium hydroxide in the presence pulp. In order to investigate selectivity and mechanism, substrate pulps obtained composites were fractionated (R30, R100, R200, R400 a sedimented fraction that passed 400 mesh wire) using Bauer-McNett unit. The main fractionation criterion therefore fiber length. pulp used CTMP (chemithermomecha...

Background. The treatment of pulp inflammation takes an important place among modern dentistry problems. Depulpated teeth in some cases become chronic source infection. They could also cause odontogenic infection the maxillofacial region. In this regard, it is to use conservative methods eliminate inflammatory process dental and preserve vitality tooth. Aim. aim study collect systematize inform...

Knowledge and understanding the anatomical configuration of individual tooth play a significant role in success of endodontic treatment, in addition to through debridement and obturation of the canals. The canal anatomy of maxillary second premolar has been studied extensively, and the presence of a significant variety of multirooted canals is relatively rare in it. A 27-year-old female reporte...

Since abnormal tooth morphology can predispose to caries and periodontal disease, careful management of fused teeth is essential. In this paper we report a rare case of a fused molar and supernumerary tooth and describe its management. Caries was removed from the tooth complex under local anesthesia. The pulp chamber of the supernumerary tooth was exposed without involvement of second molar pul...

The variations of anatomical and morphological characteristics of the teeth are very important for any practitioner. These differences in root morphology are influencing the success of the endodontic therapy and the long-term prognosis of the tooth, especially when it is an abutment for a prosthetic restoration. Before beginning an endodontic treatment, the clinician must take into account the ...

Phenotype/cell stem origin Light chain restriction surface immunoglobulin. Most cases express IgM and IgD. B-cells express CD19+, CD20+, CD22+, CD24+, CD79b+, FMC7+ and DBA44+. Lack expression of CD5 (85%), CD10, CD23, CD103 and CD123. Epidemiology In 1987, the term SLVL was introduced; 1-2% of nonHodgkin lymphomas; occurs in the elderly (med 70 yrs); sex ratio 2M/1F. Clinics Splenomegaly witho...

In order to determine the quantitative relationship between sheet strength and lignin coverage at the fiber surface, CTMP was blended with softwood bleached kraft pulp (BKP), refined softwood BKP, and hardwood BKP. The morphology of the fibers, fibers properties, fiber surface components and relative bonded area of sheets were investigated. Multi-linear regression equations of tensile strength ...

Splenic white pulp of the Aleutian skate (Bathyraja aleutica), an elasmobranch, was investigated using light and transmission electron microscopy. The major cellular constituent was plasma cells, of the typical Marshalko type, characterized by well developed rough-endoplasmic reticulum and a Golgi complex. The morphology of the rough-endoplasmic reticulum was variable, being lamellar in some ce...

Cellulose nanocrystals (CNCs) can be obtained from bamboo pulp by hydrolysis with sulfuric acid. Firstly, the authors conducted a series of experiments under different conditions, and concluded that the optimal parameters were as follows: sulfuric acid concentration 60%, temperature 45 °C, the time is 90 minutes and the solid-liquid ratio is 1:8. Then, transmission electron microscopy (TEM), Fo...

A major anatomical variant of the two-rooted mandibular first molar is a tooth with an additional distolingual third root: The radix entomolaris (RE). It is essential to anticipate and find all roots and canals during root canal treatment. Proper angulations and interpretation of radiographs help to identify pulp chamber and root anatomy. If present, an awareness and understanding of this unusu...
