Dental treatment before haematopoietic stem cell transplantation - a service evaluation.

Introduction National guidance by the Royal College of Surgeons (England) recommends a dental assessment and necessary treatment before haematopoietic stem cell transplantation (HSCT). Within the special care dentistry department in Liverpool University Dental Hospital, patients are assessed before transplant; however, the efficiency and efficacy of the service was unknown and therefore a service evaluation was indicated.Aim To evaluate the current referral process and dental care provided before patients receive HSCT.

Predictors of ethical approval and informed consent in orthodontic RCTs.

Objectives: Determine the number of orthodontic randomized controlled trials (RCTs) published in four key orthodontic journals from 1 January 2001 to 31 December 2010, whether details about ethical approval (EA) and/or informed consent (IC) were reported and identify predictors for reporting EA and IC in orthodontic RCTs.

Design: Retrospective observational study.

Setting: American Journal of Orthodontics and Dentofacial Orthopedics (AJODO), Angle Orthodontist (AO), European Journal of Orthodontics (EJO) and Journal of Orthodontics (JO) from 2001 to 2010.

Cementoblastoma in the maxilla: a case report.

The cementoblastoma is a rare, benign odontogenic tumour. It is generally asymptomatic and usually occurs in young adults. It is more common in males.

The effect of colour defective vision on shade matching accuracy.

One hundred and forty one male dental students and staff were screened for colour-defective vision. Ten colour-defective and 20 non colour-defective subjects then carried out a shade matching exercise using nine selected shades and another matched, shade tab (to test for consistency) from Vita shade guides. All shade matching took place under standard lighting conditions.

Variations in acid-etch patterns with different acids and etch times.

Research has shown that mandibular premolars have the highest rate of orthodontic bracket bond failure. Bond strength is thought to depend on the quality and quantity of enamel etch produced by the acid. Phosphoric acid is the most commonly used acid for etching before bonding.
