Three-Decade Failure to the Eradication of Refractory Infection and Recent Efforts to Eradicate the Infection.

Background: Helicobacter pylori causes dangerous and deadly diseases such as gastric cancer and duodenal ulcers. Eradication and treatment of this bacterium are very important due to the deadly diseases caused by H. pylori and the high cost of treatment for countries.

Scleral exposure alterations following Le Fort I osteotomy (with and without maxillary impaction) in skeletal class III patients: A before-and-after clinical trial.

Purpose: Exposure of sclera below the iris in natural head positions is aesthetically undesirable. Studies on post-surgical changes in inferior scleral exposure following orthognathic surgery are scarce and mostly retrospective. The aim of this clinical trial is to examine the effect of Le Fort I osteotomy, a procedure for correction of malocclusion and maxillo-mandibular deformities, on the inferior scleral exposure and overall scleral surface area in skeletal class III patients.
