Prevalence of malocclusion in Canadian children with autism spectrum disorder.

Introduction: The purposes of this study were to determine the prevalence of malocclusion among children with autism spectrum disorder (ASD) and to describe the most common malocclusion traits in this population.

Methods: This cross-sectional study included patients diagnosed with ASD aged between 5 and 18 years. Randomly selected healthy children with the same demographic characteristics comprised the control group.

Evaluation of the severity of malocclusions in children affected by osteogenesis imperfecta with the peer assessment rating and discrepancy indexes.

Introduction: Osteogenesis imperfecta is a heritable disorder affecting bone and tooth development. Malocclusion is frequent in those affected by osteogenesis imperfecta, but this has not been studied in detail. The purpose of this study was to describe and quantify the severity of malocclusions in patients with osteogenesis imperfecta.

Clinical complications in the revascularization of immature necrotic permanent teeth.

The purpose of this case series was to report on the use of a technique of revascularization for necrotic immature permanent teeth, several problems encountered, and solutions to those problems. Eighteen pulp revascularizations were performed in 2009 using the original protocol of revascularization (adapted from the AAE/AAPD joint meeting in 2007 in Chicago). The protocol consisted of opening the canal and disinfecting it with sodium hypochlorite, sealing in a triple antibiotic paste for 2-6 weeks, re-opening, re-irrigating, creating a blood clot in the canal, and sealing with an MTA barrier over the clot.
