Evaluation of pediatric dentists' knowledge and approaches to tooth discoloration.

In recent years, esthetic expectations have come to the fore in pediatric dentistry, as in every field of dentistry. Therefore, to better meet patients' expectations, the steps taken to determine and improve the current level of knowledge of pediatric dentists on tooth discoloration gain importance. This study aims to measure the knowledge levels of pediatric dentists regarding tooth discoloration.

Effect of Immediate Dentin Sealing on the Bonding Performance of Indirect Restorations: A Systematic Review.

The popular immediate dentin sealing (IDS) technique is used to improve the bond strength of indirect restorations. This systematic review assessed whether bond strength is affected by the type of aging conditions, bonding agents, flowable resin composites, impression materials, temporary materials, and/or resin cement used within the IDS procedure. A comprehensive database search of PubMed, Embase, Scopus, Ovid Medline, Web of Sciences, Cochrane Library, Dentistry & Oral Sciences Source, and ProQuest was carried out up to 30 January 2024 without publication year or language limitations.

Translated Mutant mRNA Expression Level Impacts the Severity of Dentin Defects.

Hereditary dentin defects are conventionally classified into three types of dentinogenesis imperfecta (DGI) and two types of dentin dysplasia (DD). Mutations in the dentin sialophosphoprotein (DSPP) gene have been identified to cause DGI type II and III and DD type II; therefore, these are not three different conditions, but rather allelic disorders. In this study, we recruited three families with varying clinical phenotypes from DGI-III to DD-II and performed mutational analysis by candidate gene analysis or whole-exome sequencing.
