Dentin Remineralization Around Ceramir Restoration
… mono-n-dodecyl phosphate in remineralization of dentin around root caries restorations. MATERIALS & METHODS: 45 permanent intact teeth were embedded in self-cured dental acrylic resin to expose buccal or lingual surfaces. The buccal/lingual surfaces were wet ground with carbide paper, final …

Pulp reaction to anorganic bovine dentin
A study was made to determine if heterogenous dentin, devoid of its antigenic potential, would stimulate reparative dentino-genesis in the dental pulp. The teeth of two monkeys were capped with bovine dentin mixed with methyl cellulose and histologic analysis was made at 21 and 42 days …

Occlusion of Dentin Tubules by Novel Prophylaxis Paste
… of even a thin layer of enamel can expose dentin in places where enamel is already thin, causing the patient to experience hypersensitivity. This study features novel prophylaxis paste formulations that use remineralizing agents in non-aqueous carriers to create a prophylaxis paste that …

A Species Comparative Study of the Soluble Phosphoproteins of Dentin.
The soluble phosphoproteins of the dentin have been isolated from the rabbit, cow, hog, and human. The phosphoproteins were purified by means of gel filtration and anion-exchange chromatography, and polyacrylamide gel electrophoresis. They all showed high levels of aspartic acid, serine, and …

Bond strength of calcium silicate based bioceramic sealers to dentin
… teeth were sectioned horizontally to uncover the dentin and embedded in epoxy resin (n=12 per sealer). Polyethylene tubes (3 mm diameter) placed on the dentin were filled with one of the tested sealers. After one-week incubation, specimens were submitted to a shear bond strength test. Data was …

Effect of Antibiotic Pastes on Chemical Structure and Microhardness of Radicular Dentin
… The effect these pastes have on radicular dentin is unknown. Objectives: The aim of this study was to investigate the effects of two intracanal medicaments used during endodontic regeneration, TAP and MTAP, at concentrations of 1 g/mL and 1 mg/mL, on the microhardness and chemical structure …

A Literature Review on the Effects of Smoking on Tertiary Dentin Formation
… outer layer of the root is covered in cementum. Dentin is the hard tissue that makes up the bulk of the tooth and gives structural support to the overlying enamel and cementum. Dentin also provides protection to the cellular and neurovascular elements in the pulp chamber. Dental trauma and …

Photodynamically Activated Multifunctional Chitosan Nanoparticles to Disinfect and Improve Structural Stability of Dentin
… the alterations in the ultrastructure of dentin tissue results in compromised structural integrity of root dentin leading to higher risk of fracture in root-filled teeth. The objectives of this study are twofold: 1) develop and test functionalized nanoparticles to eliminate biofilm …

A Novel Biomimetic Scaffold for Guided Tissue Regeneration of the Pulp - Dentin Complex
… in this work is the regeneration of the pulp-dentin complex (PDC), specifically the interface. Endeavors in regenerating either pulp or dentin have been successful individually, but the interface region is the anatomical and physiologic hallmark of the PDC and has not been addressed. We have …

Effect of Radiotherapy on Nano-Mechanical Properties and Chemical Composition of Tooth Enamel and Dentin
… characterized by enamel delamination near the dentin-enamel junction (DEJ) by evaluating enamel and dentin nano-mechanical properties and chemical composition before and after in vitro and in vivo radiotherapy. For the in vitro group, sections from non-carious third molars were exposed to 2 Gy …
