Background: After indirect capping, injured odontoblasts generate reactionary dentin, whereas after direct capping of a pulp exposure pulp, cells stimulate the formation of reparative dentin. The aim of this study was to evaluate and compare the effects of two direct capping agents on pulp tissue reactions: Hydrogel (a bovine serum albumin (BSA)/glutaraldehyde,) and Dycal (a calcium hydroxide-b...

The purpose of this study was to compare the dentin bond strength of three self-adhesive cements with smear layer pretreatments using a calcium-chelating agent (EDTA) and deproteinizing solution (NaOCl) and to evaluate their interfacial characteristics. Smear layer-covered dentin surfaces were pretreated with EDTA for 60 s, NaOCl for 5 and 15 s, or none. Three self-adhesive cements; Clearfil SA...

Carious dentin is partially demineralized and contains mineral crystals in the tubules. This may permit the deeper etching of intertubular dentin but prevent resin tag formation during bonding. We hypothesize that resin adhesives will produce lower bond strengths to caries-infected and caries-affected dentin compared with normal dentin. We tested this by measuring the microtensile bond strength...

This manuscript previews the introduction of significant advances in materials which are used conservative management pulp primary and permanent teeth. These posses property inducing tertiary dentin formation protection dentin-pulp complex. Calcium Hydroxide, Mineral Trioxide Aggregate (MTA), Biodentine widely discussed along with some recently introduced materials. The aim this article is to o...

Dentin sialophosphoprotein (DSPP) is a major secretory product of odontoblasts and is critical for proper tooth dentin formation. During dentinogenesis, DSPP is proteolytically cleaved into smaller subunits. These cleavages are proposed activation steps, and failure to make these cleavages is a potential cause of developmental tooth defects. We tested the hypothesis that dentin-resident matrix ...

This exploratory study proposes an original intra-life history investigation through sequential analysis of the isotopic composition carbon, nitrogen, and sulfur (CNS) on both primary secondary dentin a tooth (M1). We focus elderly woman from Longobard Italy (6th to 8th c. CE), who showed unprecedented case cranial surgery, presented in companion paper by Micarelli colleagues. Sequential stable...

Dentin matrix protein 1 (DMP1) and dentin sialophosphoprotein (DSPP) are extracellular matrix proteins produced by odontoblasts involved in the dentin mineralization. The aim this study was to compare the distribution of DMP1 and DSPP in human sound dentin vs human sclerotic dentin. Sixteen sound and sixteen carious human molars were selected, fixed in paraformaldehyde and processed for immunoh...

Direct application of dentin bonding agents onto the exposed pulp has been advocated, but in vivo studies indicate a lack of reparative dentin formation. Our objective was to investigate the role of triethylene glycol dimethacrylate (TEGDMA), a commonly used compound in dentin bonding agents, as a potential inhibitor of mineralization. Human pulp cells were exposed to different concentrations o...

Dentin dysplasia, a rare hereditary disorder of dentin formation, is characterized by normal enamel but atypical dentin formation along with abnormal pulpal morphology. It is inherited as an autosomal dominant trait. It has been divided into two clinical entities: type I (radicular) and type II (coronal). Early diagnosis and initiation of effective regular dental treatments may help the patient...

Objectives: The principle of measurement using the TCI (Tooth Coronal Index) method is to compare pulp chamber height with a person's chronological age based on formation secondary dentin. purpose this study estimate in lower canines periapical radiographs measurement.
 Materials and Methods: This an observational analytic 42 samples parallel technique canines. Samples were measured for CH...
