Knowledge and practice towards early orthodontic problems among general dentists and paediatric dentists.

Abstract

To assess the knowledge, practice and challenges faced by general dental practitioners (GDPs), paediatric dentists (PDs) and postgraduate paediatric dentistry students (PGPDSs) in diagnosing and managing early orthodontic problems. Cross-sectional study. A total of 159 dentists were enrolled in this study (121 GDPs, 21 PDs and 17 PGPDSs). Data were collected using a self-administered questionnaire involving two sections. Section A included questions regarding demographic features and orthodontic practice. Section B included photos of 12 orthodontic cases that needed early intervention. Knowledge and practice were assessed using six questions for each case that was then rated using predefined scores of poor (score <50%), average (score 50%-75%) and good (score >75%). The knowledge scores regarding the identification of early orthodontic problems were average among the three groups with GDPs having the lowest score (P = 0.0001). The knowledge scores regarding the selection of optimal treatment time were average among the PDs and PGPDSs, and poor among GDPs. GDPs tended to refer most of their cases to an orthodontist except for cases of thumb sucking. PDs and PGPDSs were more confident in treating anterior crossbite, thumb sucking habits and delayed eruption of incisors. All participants scored 'poor' regarding the selection of an appropriate orthodontic appliance. There was no significant correlation between knowledge and practice (P > 0.05). PDs and PGPDSs showed higher knowledge and practice scores when compared to GDPs. For all three groups included in this study, lack of clinical skills was the main reason for not treating early orthodontic problems.
