X-linked hypophosphatemia (XLH) is a rare genetic disorder that disrupts skeletal and dental mineralization. In addition to rickets in children, XLH patients also have frequent spontaneous dental abscesses that increase the risk of tooth loss and may lead to facial cellulitis. Hypomineralized and hypoplastic dentin is the main driver of these infections.

There are many variables having an impact on the spoken language acquisition of deaf and hard of hearing (DHH) children; therefore, it is critical for parents and professionals to have appropriate tools to monitor language acquisition. The Spoken Language Checklist (SLC) was developed to monitor and identify developmental milestones in a user-friendly checklist format that includes norms. The availability of the SLC will help parents and professionals to monitor the spoken language development of DHH children and provide interventions that should any delays be observed.

Introduction: Most malocclusions are dysfunctional in origin and multidisciplinary care appears essential to correct as well as to maintain the orthopedic treatments performed. However, some "re-"educational therapies do not always deliver the desired results and the persistence of dysfunctions can thus compromise the stability of long-term results of orthodontic treatments.

Material And Method: Through a review of the literature, this article analyzes the former and current theories regarding maxillofacial rehabilitation.

A split-mouth randomized clinical trial was carried out to assess the effectiveness of sealants in preventing carious ICDAS (International Caries Detection and Assessment System) 3-6 lesions within a 2-year follow-up. We evaluated the effectiveness of 2 types of resin-based sealants, with and without fluoride, their retention rates, and the caries risk factors related to their outcomes. The study included 663 tooth pairs in 400 children (aged 5-15 years) considered to be at high individual caries risk (ICR) and presenting permanent molars free of caries or affected by ICDAS 1-2 lesions.

Background: Since the 2000s, different epidemiological studies focusing on the prevalence or the aetiology of DE in adolescents recognised them as an at-risk population due to their eating behaviours. None was carried out in French adolescents. The primary objective of this study was to assess the prevalence of dental erosion (DE) using the total BEWE score among adolescents in the department of Alpes Maritimes, France.

Claudin-16 protein (CLDN16) is a component of tight junctions (TJ) with a restrictive distribution so far demonstrated mainly in the kidney. Here, we demonstrate the expression of CLDN16 also in the tooth germ and show that claudin-16 gene (CLDN16) mutations result in amelogenesis imperfecta (AI) in the 5 studied patients with familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC). To investigate the role of CLDN16 in tooth formation, we studied a murine model of FHHNC and showed that CLDN16 deficiency led to altered secretory ameloblast TJ structure, lowering of extracellular pH in the forming enamel matrix, and abnormal enamel matrix protein processing, resulting in an enamel phenotype closely resembling human AI.

Introduction: Local anaesthesia is commonly used in paediatric oral healthcare. Infiltration anaesthesia is the most frequently used, but recent developments in anaesthesia techniques have introduced an alternative: intraosseous anaesthesia. We propose to perform a split-mouth and parallel-arm multicentre randomised controlled trial (RCT) comparing the pain caused by the insertion of the needle for the injection of conventional infiltration anaesthesia, and intraosseous anaesthesia by the computerised QuickSleeper system, in children and adolescents.

Background: To ensure evidence-based decision-making in pediatric oral health, Cochrane systematic reviews that address topics pertinent to this field are necessary. We aimed to identify all systematic reviews of paediatric dentistry and oral health by the Cochrane Oral Health Group (COHG), summarize their characteristics and assess their methodological quality. Our second objective was to assess implications for practice in the review conclusions and provide an overview of clinical implications about the usefulness of paediatric oral health interventions in practice.

In the literature, the enamelin gene ENAM has been repeatedly designated as a possible candidate for caries susceptibility. Here, we checked whether ENAM variants could increase caries susceptibility. To this aim, we sequenced coding exons and exon-intron boundaries of ENAM in 250 children with a severe caries phenotype and in 149 caries-free patients from 9 French hospital groups.

Genetic approaches have shown that several genes could modify caries susceptibility; AmelogeninX (AMELX) has been repeatedly designated. Here, we hypothesized that AMELX mutations resulting in discrete changes of enamel microstructure may be found in children with a severe caries phenotype. In parallel, possible AMELX mutations that could explain resistance to caries may be found in caries-free patients.

Objectives: Evidence-based comparisons of interventions can be challenging because of the diversity of outcomes in randomized controlled trials (RCTs). We aimed to describe outcomes in RCTs assessing pulp treatments for primary teeth and to develop a core set of component outcomes to be part of composite outcome defining the failure of a pulp treatment.

Methods: We systematically reviewed articles of RCTs comparing pulp treatments for primary molars published up to February 2012.
