introduction: this study was carried out to evaluate the bacterial leakage of root canal fillings when cavity varnish containing 5% fluoride (duraflur) was used as root canal sealer. methods and materials: root canals of 88 straight single-rooted teeth were prepared. eighty teeth were randomly divided into 3 experimental groups ( n =20) and two positive and negative control groups of ten each. ...

We construct infinitely many distinct simply connected Stein fillings of a certain infinite family of contact 3-manifolds. Math. Res.

In this note we construct infinitely many distinct simply connected Stein fillings...

In this paper we will give three infinite families of examples of nonhyperbolic Dehn fillings on hyperbolic manifolds. A manifold in the first family admits two Dehn fillings of distance two apart, one of which is toroidal and annular, and the other is reducible and ∂-reducible. A manifold in the second family has boundary consisting of two tori, and admits two reducible Dehn fillings. A manifo...

  Objective: Diagnosis of vertical root fractures (VRFs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. Despite Cone Beam Computed Tomography (CBCT) has significantly enhanced image quality compared to digital radiography (DR) which aid the diagnosis, artifacts has remained as a problem in VRF detection . ...

AIM To investigate the technical quality of nonsurgical root canal treatment performed by endodontists in Melbourne, Australia. METHODOLOGY Clinical and radiographic records of 100 sequential nonsurgical patients were obtained from each of six endodontists working in private practice. The following variables were analysed: proximity of root filling to radiographic apex; homogeneity and radiod...

Bakery products with various fruit fillings are very popular due to their fresh-fruity fragrance. Said fruit fillings, which are added to the pastries after the baking process, should have, besides the required sensory properties, also very good physicochemical characteristics regarding processing (dosing, pumping, injecting). Heat stable fruit fillings should only be used for filled pastries b...

OBJECTIVES The present study was set up to explore (1) a potential association between a person's caries risk profile and the presence or absence of root-filled teeth, and (2) the caries risk in endodontically treated teeth. STUDY DESIGN Two hundred Saudi adults were divided into an Endodontic Group (EG; n = 100), with a minimum of 2 root-filled teeth, and a Non-Endodontic Group (NEG; n = 100...
