background. maximum sealing ability or adhesion of endodontic sealers can be achieved after an effective removal of smear layer. endodontic irrigants assist in adequate removal of smear layer and thus improve the retention mechanism. the aim of this study was to evaluate the effect of two different root canal irrigating solutions (5.25% naocl followed by 17% edta and qmix) on the apical sealing...

We prove the ‘oval conjecture’ for planar partition functions, which says that the shift plane and the translation plane defined by a planar partition function form an oval pair of planes in the sense that each non-vertical line of one plane defines a topological oval in the projective closure of the other. The proof uses covering space techniques, and we have to assume that the generating func...

Background: The prevalence of TMD (temporomandibular disorder) in children and early adolescents varies widely. can cause permanent facial deformities affect occlusion speech, which will growth, development, quality life. For prevention, detection is needed. However, often not possible due to a lack understanding the normal shape condyle. Research on condyle symmetry has been much done. Purpose...
