Information on the knowledge of the mental foramen is important in clinical dentistry. The present study was undertaken to determine the most common position of mental foramen in randomly selected Indian population. Total 204 panoramic radiographs were evaluated, among them 184 were studied in terms of site, gender differences, symmetry of location, shape, distance from midline and continuity o...

Objectives. To compare the effectiveness of four instrument systems for preparing oval root canals: manual instrumentation (Step-Back technique), ProTaper Universal, ProTaper Next, and Wave One. Material and Methods. For the purpose of this assessment, 60 teeth extracted for orthodontic or periodontal reasons, specifically canines and premolars with full coronal and root anatomy, were used and ...

Aim of the study: to evaluate root filling remnants after secondary canal treatments (SRCTs) oval-shaped canals with X-rays and cone beam computed tomography (CBCT). The SRCTs were performed using reciprocating NiTi instruments. Methods: Single-rooted teeth (N = 64) randomly treated Reciproc Blue (RB) filled AH Plus/single (SC group) or Plus/Guttafusion (GF group). After seven days storage in H...

In case of hepatic damage, the liver uses a unique regeneration mechanism through proliferation of hepatocytes. If this process is inhibited, bipotent oval stem cells proliferate and differentiate to hepatocytes and bile ducts, thus restoring liver mass. Although oval cell accumulation in the liver is often associated with inflammatory processes, the role of lymphocytes in oval cell-mediated he...

Say that a surface in S ⊂ R has the central plane oval property, or cpo, if • S meets some affine plane transversally along an oval, and • Every such transverse plane oval on S has central symmetry. We show that a complete, connected C surface with cpo must either be a cylinder over a central oval, or else quadric. We apply this to deduce that a complete C surface containing a transverse plane ...

Introduction: Basiocciput is the part of occipital bone present on inferior aspect skull. Fossa Navicularis Magna-an osseous defect a variation in normal anatomy basiocciput. Lately few case reports presented this fossa as cause spread infection from nasopharynx to brain resulting meningitis and osteomyelitis.

Terim Kapakin K.A., F. Bozkurt, R. Haziroğlu: Sebaceous Adenocarcinoma in a Cat. Acta Vet. Brno 2008, 77: 123-125. In this study, the sebaceous gland adenocarcinoma was presented in the external auditory canal of a 10-year-old female tabby cat. There were three tumoural masses located macroscopically in the external auditory canal in the dimensions of 0.2 × 0.5, 0.3 × 0.5, and 0.1 × 0.1 cm, and...

Congenital anomaly of the oval window with an abnormal facial nerve course is an uncommon embryological defect, which is related to the underdevelopment of second branchial arch derivatives. Some treatments for improving hearing levels are available; these include hearing aids, vestibulotomy, neo-oval window formation, and stapes surgeries, including incudostapedotomy and malleostapedotomy. How...

Growing evidence has shown that hepatic oval cells, also named liver progenitor cells, play an important role in the process of liver regeneration in various liver diseases. Oval cell proliferation has been reported in hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) and chronic liver disease. Studies have found expression of HBV surface and core antigens in oval cells in the l...

T HIS study is a supplement to my previous article entitled “A Stereomicroscopic Study of the Root apices of 400 Maxillary and Mandibular Anterior Teeth. “l I have thus completed the analysis of posterior as well as anterior teeth.2 The purpose of this article is to establish with greater precision than has heretofore been attained the morphology of the canal at the root apex, the major apical ...
