Temperament and past behaviour can predict behaviour success for nitrous oxide sedation.

Background: There is currently insufficient evidence on potential predictors of a child's behaviour with nitrous oxide (NO) sedation.

Aim: To examine the association between a child's temperament and behavioural outcomes during dental treatment with NO sedation, and the child's perception to NO sedation.

Design: At the first visit (dental treatment visit), temperament was assessed using the Child Behaviour Questionnaire-Short Form and behaviour was assessed by an independent rater using the Venham Behaviour Rating Scale.

Accuracy of the American Association of Endodontists diagnostic criteria for assessing pulp health in primary teeth.

Objectives: There is a lack of studies evaluating the accuracy of the 2009 American Association of Endodontists (AAE) diagnostic criteria for diagnosing pulpal health in primary teeth. This study aimed to estimate and correlate the diagnostic accuracy of clinical diagnosis of reversible and irreversible pulpitis using the 2009 AAE criteria with histological findings in primary teeth.

Methods: Eighty primary teeth that were clinically diagnosed with normal pulp (n = 10), reversible pulpitis (n = 30), irreversible pulpitis (n = 30) and pulp necrosis (n = 10) were collected.

Tooth autotransplantation with 3D-printed replicas as part of interdisciplinary management of children and adolescents: Two case reports.

The management of missing teeth as a result of dental trauma or associated with hypodontia in children and adolescents presents as a clinical challenge for the dental team. One of the options that is regaining popularity is dental autotransplantation. To improve autotransplantation outcomes, careful interdisciplinary planning, surgical simulation using cone beam computed tomography images and three-dimensional-printed teeth replicas should be undertaken for presurgical preparation.
