Abstract
The present study aimed to assess the perception and knowledge of Brazilian orthodontists on the ideal moment to treat Class II malocclusions. Questionnaires with open, semi-open and close questions were sent by e-mail to 1653 Brazilian orthodontists. These orthodontists were registered in the Brazilian Association of Orthodontics and Dentofacial Orthopedics (ABOR). One-hundred and three (9.86%) Orthodontists replied to the questionnaires. Most of them were males (60.5%) with specialization as the highest level of professional qualification (59.9%). Most of the orthodontists (51%) reported preference for treating Class II malocclusions in late mixed dentition, followed by the early mixed dentition (29%). The age range between 10 and 12 years old figured as the most prevalent in patients searching for treatment (42.7%). Most of the patients searching for treatment were females (69.7%). Preferences for functional orthopedic appliances were reported by 35% of the orthodontists. Brazilian orthodontists revealed a trend for treating patients with Class II malocclusions in the late mixed dentition. Female patients aged from 10 to 12 years old represented the majority of patients that search for orthodontic treatment. Functional orthopedic appliances were preferred by Brazilian orthodontists for treating Class II malocclusions.

Summary
Class II malocclusions are represented by the distal occlusal position of the lower molars in relation to their antagonist. The late intervention is founded on the correction of the malocclusion in the permanent dentition in a single phase (without orthopedic therapeutics) (Cançado et al 2009) In this protocol, skeletal and dental corrections are performed simultaneously (Calheiros et al 2008). Skeletal and dental corrections are performed simultaneously (Calheiros et al 2008) This protocol emerged as an alternative to the lack of patient cooperation in early interventions, as well the high cost of these interventions (dental movement is less evident before the pubertal growth spurt, which makes the treatment last longer) (Calheiros et al 2008). The present study was justified considering I) the uncertainty in the scientific literature on the treatment of patients with Class II malocclusion; II) the lack of information on the ideal moment for treating these patients in Brazil; and III) the lack of information on the systems/appliances used by Brazilian orthodontists in the treatment of Cass II malocclusions
