A curriculum for behaviour and oral healthcare management for dentally anxious children-Recommendations from the Children Experiencing Dental Anxiety: Collaboration on Research and Education (CEDACORE).

Background: Dentists need training in the management of children's anxiety (DA), fear (DF) and behaviour management problems (DBMP) but little is known of their competence on this topic.

Aim: To report dentists' opinions and attitudes about protective stabilisation and pharmacological techniques for the management of children with DA/DF/DBMP; to propose a postgraduate curriculum focussing on DA/DF/DBMP.

Design: A survey of 301 Brazilian dentists and later a modified Delphi process to outline the curriculum in two phases: (a) face-to-face discussions with 33 early career researchers mentored by six researchers, both from UK and Brazil; (b) online discussions by eight early and senior researchers on the knowledge, experience, and competencies necessary for a specialist in paediatric dentistry in Brazil that should be included in the core curriculum of postgraduate courses.

Comparison of marginal microleakage of flowable composite restorations in primary molars prepared by high-speed carbide bur, Er:YAG laser, and air abrasion.

Purpose: The purpose of this study was to assess in vitro the influence of 3 cavity preparation devices (carbide bur, Er:YAG laser, and air abrasion) on the microleakage of flowable composite restorations in primary teeth.

Methods: Fifteen primary second molars were selected, and Class V cavities were prepared on the buccal/lingual surfaces, being assigned to 3 groups (n= 10). Group 1 (control) was prepared using a high-speed handpiece and was acid etched.
