Effect of Different Tapered Gutta Percha Cones in Apical Microleakage of Human Root Canal Obturation

Background and purpose: Gutta-percha is generally accepted as the main canal filler. Standard gutta-percha cones are available in 2-10% tapers. The purpose of this study was to compare apical microleakage of canals obturated with different tapers of gutta-percha, using the protein penetration technique. Materials and methods: In this study, 96 maxillary anterior teeth were selected and were pr...

The radio-opaque appendicolith--its significance in clinical practice.

Four cases are reported, in whom radiologically opaque appendiceal coproliths (appendicoliths) were recognised on plain abdominal radiographs. These were undertaken for diagnostic purposes, in patients with right-sided abdominal pain, in whom the diagnosis was not immediately apparent. The pathology, radiological features, and clinical significance of the phenomenon are discussed, and the assoc...

In vivo tissue compatibility of two radio-opaque polymeric biomaterials.

Polymeric biomaterials featuring intrinsic radio-opacity continue to attract considerable scientific attention. This work focusses on two polymers that contain covalently bound iodine, rendering the materials radio-opaque. The first material is hard, transparent and glass-like, and consists of methyl methacrylate, 2-(2'-iodobenzoyl)-ethyl methacrylate (1) and 2-hydroxyethyl methacrylate (HEMA),...
