introduction: the aim of this study was to determine the effect of different luting agents on fracture resistance of endodontically treated teeth restored with casting post. materials and methods: in this experimental study, forty extracted human maxillary central incisors teeth with the mean length of 23mm were randomly assigned in to four groups. all the studied teeth were caries free without...

To study human evolution [4], researchers sometimes use microstructures found in human teeth and their knowledge of the processes by which those structures grow. Human fetuses begin to develop teeth in utero. As teeth grow, they form a hard outer substance, called enamel, through a process called amelogenesis. During amelogenesis, incremental layers of enamel form in a Circadian rhythm. This rh...

introduction: the aim of this randomized clinical trial was to compare the histologic pulp tissue response to one-step direct pulp capping (dpc) and miniature pulpotomy (mp) with mineral trioxide aggregate (mta) after application of dexamethasone in healthy human premolars. methods and materials: forty intact premolars from 10 orthodontic patients, were randomly chosen for dpc ( n =20) or mp ( ...

Poor DNA preservation is the most limiting factor in ancient genomic research. In the majority of ancient bones and teeth, endogenous DNA molecules represent a minor fraction of the whole DNA extract, rendering shot-gun sequencing inefficient for obtaining genomic data. Based on ancient human bone samples from temperate and tropical environments, we show that an EDTA-based enzymatic 'pre-digest...

Introduction: Preservation of pulp tissue can extend the long-term survival teeth through relatively simple restorative procedures. Objective: To analyze literature on success indirect capping in primary and permanent teeth, as well direct partial complete pulpotomy mature immature teeth. Methodology: An electronic search was performed during January 2022 PubMed, SCOPUS Google Scholar databases...
