Electrical stimulation to clinically identify position of the lingual nerve: results of 50 subjects with reliability and correlation with MRI.

Purpose: Recently we described mapping of the lingual nerve clinically in patients using electrical nerve stimulation. This paper reports results of a larger study with inter- and intra-observer reliability and comparison with positional measurements from magnetic resonance imaging (MRI).

Methods: In 50 healthy participants, measurements were taken when subjects felt a tingling sensation in the tongue induced by a stimulation probe over the lingual nerve.

Is the number of procedures completed a valid indicator of final year student competency in operative dentistry?

Introduction Concerns regarding the preparedness of dental graduates often focus on the number of procedures undertaken before qualification.Aims To assess the validity of numerical requirements in determining whether a student has sufficient competency to graduate.Materials and methods In total, 50,821 observations of student activity while on the restorative clinic, for two integrated student cohorts (n = 139), were continuously recorded using the LiftUpp system from their third year to graduation.

Dental Pain: Dentine Sensitivity, Hypersensitivity and Cracked Tooth Syndrome.

Dentine hypersensitivity is a frequently encountered patient complaint that can present with a number of associated factors including erosion and abrasion. the hydrodynamic mechanism responsible for dentine hypersensitivity is intimately related to the anatomical and physiological composition of teeth. Alterations to the integrity of the enamel and dentine through processes of trauma, decay and toothwear can increase dentine permeability.

Managing the Unstable Mandibular Complete Denture – Tooth Placement and the Polished Surface.

Constructing satisfactory conventional mandibular complete dentures is often challenging in comparison to the upper counterpart partially due to differences in the anatomy of the denture-bearing area. This problem is exaggerated in the atrophic mandible, where supporting structures are frequently ill-defined and suboptimal in quality. Implant-retained prostheses offer well recognized benefits but are not always a feasible options, so conventional methods must be relied upon.
