[Could the distalization of the mandibular molars be facilitated? A new therapeutic method].

A young patient complained of missing inferior second premolars. Clinical and cephalometric parameters suggested the indication for a prosthetic solution, opening the spaces between first premolars and molars, aiming to correct occlusal relationships. Space closure was thus excluded.

Orthodontists' perspectives regarding treatment timing: a cross-national study.

Aim: To describe the results of a cross-national survey of orthodontists' preferences regarding initiating treatment at various dentition stages. Previous research has demonstrated high acceptance of early intervention by parents and children, and, in many cases, better compliance with treatment protocols among younger children than among adolescents.

Methods: The current study questioned orthodontists in three countries.

Extractions as a form of interception in the developing dentition: a randomized controlled trial.

Objective: To determine if the extractions of lower primary canines are an effective procedure to relieve crowding of the labial segment.

Study Design: randomized controlled trial. Subject sample: 83 cases were collected in clinics in Italy, Germany and Wales.

4.2 Clinical records and global diagnostic codes.

A clinical record should include the personal demographic details of the patient, health status, diagnostic information and management/treatment options. However, clinical records are of little use without effective filing and retrieving systems. Coding is therefore necessary to deal with large amounts of differing data and a global coding system could be effectively developed through the use of information technology.
