Abstract:

Background: Improvement in dentistry shows some progresses, due to patients awareness on the importance of dental care. Cervical lesion is the most common phenomenon which oftenly found 46.36% in man and 38.13% in woman. Cervical lesions need composite restoration for treatment to stop the process of tissue damage. The process of adhesion of composite restoration material to the structure of the tooth is not easily separated and it needs optimal function in the oral cavity. Application of dentin bonding agents to attach the composite is needed. Selection of HEMA-based bonding material and Hema

For the prevention of recurrent and secondary caries of teeth, as well as bullets, antiseptic treatment of the carious cavity, dentine adhesives, laser radiation, etc. are used. However, these methods do not allow achieving effective decontamination and obturation of dentine tubules, in which pathogenic microflora can continue to persist. In the experimental treatment of dentin caries using electron microscopy, the effectiveness of a new technique of galvanophoretic nanoimpregnation of dentin with nanoparticles of a complex preparation of copper-calcium hydroxide was studied.

Abstract:

Deep caries progress highlights the gradual shift from reactionary to reparative tertiary dentine as main feature illustrated by transition between the secondary and tertiary dentin. Three sorts of odontoblasts are described to exhibit their dentinogenic potential in genesis of reparative dentine, the still active primary odontoblasts, the formerly quiescent odontoblasts recently reactivated by molecular signals sent from carious lesion, and the secondary odontoblasts resulting from pulp stem cells. This complex cellular secretor involvement in dentinogenesis presume a range of resulting matri

Abstract: Dentin hypersensitivity is one of the most common dental problems. It can be found in both sexes, especially in the elderly. The discomfort or pain experienced in cases of dentin hypersensitivity occurs due to the unprotected surface by enamel in the crown or by cementum in the tooth root area. The characteristic of dentin hypersensitivity is that the pain suffered is acute, sharp but short in the unprotected dentin. This review was aimed to discuss about the etiology, stimulatory transmission mechanisms, and management of dentine hypersensitivity.Keywords: dentin hypersensitivity; p

Abstract:

fracture resistance in dentin is crucial for maintaining the structural integrity of a vital or endodontically treated tooth, particularly as aging and restorative interventions exacerbate mechanical vulnerabilities. This article explores the biomechanical properties of dentin, focusing on intrinsic toughening mechanisms such as crack deflection, bridging, and microcracking, which act to diminish crack propagation. The composite-like structure of dentin, comprising mineralized collagen fibrils within a heterogeneous matrix, facilitates a balance between stiffness and flexibility, resisting mul

Abstract:

It is widely held that the hardness and modulus of dentin increase in proportion to the mineral concentration. To test this belief, we measured hardness and modulus of normal dentin and an altered form of dentin without gap-zone mineralization in wet and dry conditions by AFM nanoindentation to determine if the modulus and hardness scale linearly with mineral concentration. Mineral concentrations in the mid-coronal location of the normal and altered dentins were 44.4 vol% and 30.9 vol%, respectively. Surrounding the pulp of the altered dentin was a region of higher mineralization, 40.5 vol%. T

Abstract:

Dead tracts are dentin areas characterized by degenerated odontoblastic processes; may result from injury caused by caries, attrition, erosion, or cavity preparation. Odontoblasts can also form tertiary dentin, as a response to injury, in association with caries, trauma, or restorative procedures. Generally, this dentin is less organized than primary and secondary dentin and mostly localized to the site of injury. The reactive dentin formation that lays under caries, the pulp displays chronic inflammation and tertiary dentinogenesis takes place on the inner walls of the pulp space, in the regi

ABSTRACT Objective: The main objective of this study is to assess the effect of the adhesive mode and chlorhexidine (CHX) on the microtensile strength of a universal bonding agent to sound and caries-affected dentins. Materials and Methods: Six intact third molars and six decayed third molars were sectioned to obtain two middle dentin specimens per tooth. Prime and Bond Elect Universal (Dentsply) was applied to specimens in two different modes: Etch-and-rinse (ER, phosphoric acid for 15s) and self-etch (SE, no phosphoric acid). 2% CHX (Cavity Cleanser, Bisco) was applied to both dentins for 30

ABSTRACT Background: Bioactivity refers to the ability of a material to interact with living organisms or biological systems in a way that elicits a specific response. In the context of materials science and medicine, bioactivity is particularly important because it can determine the suitability of material for various applications. Objective: To evaluate and compare different commercially available calcium silicate-based materials regarding: 1. Morphological and elemental analysis at the dentin/material interface. 2. Calcium and silicon release and uptake by adjacent root canal dentine by eva

Abstract:

Dental pulp tissue engineering (TE) endeavors to regenerate dentin/pulp complex by combining a suitable supporting matrix, stem cells, and biochemical stimuli. Such procedures foresee a matrix that can be easily introduced into the root canal system (RCS) and tightly adhere to dentin walls to assure the dentin surface’s proper colonization with progenitor cells capable of restoring the dentin/pulp complex. Herein was investigated an injectable self-setting hyaluronic acid-based (HA) hydrogel system, formed by aldehyde-modified (a-HA) with hydrazide-modified (ADH), enriched with platelet lysate
