Comparison of the fracture resistance of the teeth prepared with ProTaper Universal, ProTaper Next, and ProTaper Gold rotary files

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1421-1425, December 2022., 2022
Abstract Objectives Root canal preparation can lead to cracks on the roots by creating stresses on the root canal walls, which decreases the fracture resistance of the tooth. The present study compared the fracture resistance of the teeth prepared by the ProTaper Universal (PTU), ProTaper Next (PTN), and ProTaper Gold (PTG) rotary file systems ...

Differential preservation of endogenous human and microbial DNA in dental calculus and dentin

Scientific Reports, 2018
Dental calculus (calcified dental plaque) is prevalent in archaeological skeletal collections and is a rich source of oral microbiome and host-derived ancient biomolecules.

Telediagnosis of dental caries: Possible or impossible? A pilot cross‐sectional study

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1614-1622, December 2022., 2022
Abstract Objectives The aims of this study were to evaluate the effectiveness of teledentistry (based on a home intraoral imaging protocol) in detecting dental caries and to assess the accuracy of this method compared to clinical examination. Methods Forty‐three patients were recruited for the study. Using a protocol for taking intraoral photographs at

Viscoelastic Fracture of Biological Composites [PDF]

Journal of the Mechanics and Physics of Solids 59, 2279 (2011), 2011
Soft constituent materials endow biological composites, such as bone, dentin and nacre, with viscoelastic properties that may play an important role in their remarkable fracture resistance. In this paper we calculate the scaling properties of the quasi-static energy release rate and the viscoelastic contribution to the fracture energy of various ...

Comparative microleakage outcomes of different techniques used for creating the occlusal anatomy in occlusal direct restorations using the dental operating microscope

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1623-1629, December 2022., 2022
Abstract Objectives Microleakage in direct dental restorations is a primary causal factor in the restoration's failure. The aim of this study was to evaluate whether the technique for occlusal layering of the composite resin (the use of brush adaptation, the use of magnification, cusp build‐up, stamp technique) has any effect on microleakage of direct ...

The Difference of Structural State and Deformation Behavior between Teenage and Mature Human Dentin

International Journal of Biomaterials, 2016
Objective. The cause of considerable elasticity and plasticity of human dentin is discussed in the relationship with its microstructure. Methods. Structural state of teenage and mature human dentin is examined by using XRD and TEM techniques, and their ...

Dentin Priming with Amphipathic Antimicrobial Peptides

Journal of dentistry research, 2019
The evolution of bonded restorations has undergone great progress over several decades. Nonetheless, life spans of bonded restorations are limited mainly because of the eventual incidence of recurrent caries. Over time, water and waterborne agents (acids,

Evaluating the shear bond strength and remineralization effect of calcium silicate‐based and conventional self‐adhesive resin cements to caries‐affected dentin

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1630-1637, December 2022., 2022
Abstract Objective Given the importance of preserving caries‐affected dentin (CAD) in conservative dentistry, the shear bond strength (SBS) of different resin cements to CAD has been investigated. Here, we aimed to compare the SBS and remineralizing effect of a calcium silicate (TheraCem) and conventional self‐adhesive cement (Panavia SA) on the SBS of

Measurement of hepatitis B virus DNA in fresh versus processed dentin from chronically infected patients

Journal of Translational Medicine, 2018
Background Demineralized dentin matrix (DDM) is commonly used as a bone-graft substitute. This study measured and compared human hepatitis B viruses (HBV) DNA in fresh dentin to that of dentin processed into DDM extracted during dental treatment from HBV-

The comparative evaluation of the effects of quercetin, α‐tocopherol, and chlorhexidine dentin pretreatments on the durability of universal adhesives

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1638-1644, December 2022., 2022
Abstract Objective The aim of this study was to evaluate and compare the effects of chlorhexidine, quercetin, and α‐tocopherol on the shear bond strength of universal adhesives in the short (24h) and long term (6 months). Material and Methods Ninety‐six extracted sound molars were collected and divided randomly into four groups: control (no treatment),
