Abstract

AIM: The aim of the study was to investigate how widespread is the use of the 2 x 4 appliance among Italian general dentists and specialists in orthodontics, as well as the type of treatment employed and length of use. METHODS: We conducted a nationwide cross-sectional survey from July 14, 2016 to January 12, 2017 using an online questionnaire of 8 multiple choice questions, created by the SurveyMonkey® Company, on a population of Italian dentists and specialists in orthodontics affiliated with the Italian Society of Paediatric Dentistry (SIOI). This was made to assess how many clinicians knew and used this device in their clinical practice. We included 200 Italian dentists, 99 specialists in orthodontics and 101 general dentists of a mean age of 45 ± 15 years.
