An Overview of the Surgical Correction of Dentofacial Deformity.

The correction of severe dentofacial discrepancies involving a combination of orthodontic and surgical therapies (termed ‘orthognathic treatment’) is commonplace. There is an abundance of evidence within this field but it is often inconsistent. This article is an evidence-based overview of such treatments and is aimed at the general dental practitioner.

Efficacy of desensitizing dentifrices to occlude dentinal tubules.

Dentine hypersensitivity occurs when patent dentinal tubules are subjected to external stimuli, with pain being reduced by products that occlude tubules. This study compared the efficacy of a recently developed arginine-containing dentifrice, two established strontium-based products, and a fluoride control to occlude tubules when subjected to acid challenge. Dentine specimens with patent tubules were divided into four groups that were treated with a slurry consisting of one of the pastes mixed with stimulated human saliva.

How consultants, hospitals, trusts and deaneries affect pre-registration house officer posts: a multilevel model.

Objective: To examine variation in reported quality and working conditions of pre-registration house officer (PRHO) posts. To use multilevel modelling to determine how much of the variation was due to the effects of consultant firms, hospitals, trusts and deaneries, as well as variation at the level of the individual doctor.

Design: Questionnaire survey of national sample of PRHOs at the end of the pre-registration year.
