Clinical assistant training in orthodontics--how effective is it?

Area of Science:

• Dental research
• Orthodontic treatment evaluation
• Clinical assistant training outcomes

Background:

• Assessing the efficacy of specialized training programs in dentistry.
• Evaluating the quality and quantity of orthodontic care provided by general dentists.
• Understanding the impact of clinical assistant training on orthodontic treatment delivery.

Purpose of the Study:

• To investigate the quantity and quality of orthodontic treatment performed by dentists after completing a 2-year orthodontic clinical assistant training program.
• To analyze treatment outcomes and identify factors influencing treatment volume.

Main Methods:

• Retrospective analysis of orthodontic treatments completed by 18 dentists over a 12-month period.
• Assessment of initial treatment need and treatment outcomes using study models.
• Evaluation of treatment quality using the Index of Orthodontic Treatment Need (IOTN) and Peer Assessment Rating (PAR) indices.

Main Results:

• The median number of orthodontic cases treated per dentist was 37 (range: 2–488).
• 72.9% of evaluated cases had a clear dental health need for orthodontic treatment.
• The mean post-treatment PAR score was 9.2, with 72% of dentists achieving a score of 10 or less.

Conclusions:

• Orthodontic treatment outcomes achieved by the clinical assistants were similar to those reported in other similar training schemes.
• A notable proportion of dentists treated a low volume of orthodontic patients, while two treated a very high volume.
• The findings suggest variability in practice patterns and patient load among dentists post-training.
