Early class III protraction facemask treatment reduces the need for orthognathic surgery: a multi-centre, two-arm parallel randomized, controlled trial.

Objective: To evaluate whether patients who had received early class III protraction facemask treatment were less likely to need orthognathic surgery compared with untreated controls. This paper is a 6-year follow-up of a previous clinical trial.

Design: Multi-centre 2-arm parallel randomized controlled trial.

Is early Class III protraction facemask treatment effective? A multicentre, randomized, controlled trial: 15-month follow-up.

Objective: To investigate the effectiveness of early class III protraction facemask treatment in children under 10 years of age.

Design: Multicentre, randomized controlled trial.

Setting: Eight UK hospital orthodontic units.

A randomized clinical trial to compare the Goshgarian and Nance palatal arch.

The aim of this trial was to evaluate whether a Nance or Goshgarian palatal arch was most effective for prevention of mesial drift, distal tipping, prevention of mesio-palatal rotation of the upper first permanent molars, and patient comfort and ease of removal. Patients were recruited from a district general hospital and a specialist orthodontic practice and randomly allocated to a Goshgarian (n = 29) or a Nance (n = 28) group. Pre-treatment study models (T1) were taken followed by the placement of the palatal arch, premolar extractions, and upper and lower fixed appliances.

Polymorphous low-grade adenocarcinoma--a rare and aggressive entity in adolescence.

Polymorphous low-grade adenocarcinoma (PLGA) is an uncommon tumour that usually affects the minor salivary glands, particularly in the palate. It is rare in young patients, and here we report a case in a teenage girl. She presented at the age of 16, although the lesion had been noticed 2 years previously.
