Dental Traumatology, Volume 39, Issue 1, Page 49-56, February 2023., 2023 Abstract Background/Aim In case of crown fractures after traumatic dental injuries, the affected teeth can be restored either with reattachment of the fractured fragment or with a direct composite restoration. So far, longevity data for reattachments and direct composite restorations with regard to different failure types (pulp necrosis and infection ...

Trace element distribution in human teeth by x-ray fluorescence spectrometry and multivariate statistical analysis [PDF]
arXiv, 2014 X-ray fluorescence spectrometry (XRFS) was used as a multielement method of evaluation of individual whole human tooth or tooth tissues for their amounts of trace elements. Measurements were carried out on human enamel, dentine, and dental cementum, and some differences in tooth matrix composition were noted.

Bitewing Radiography Semantic Segmentation Base on Conditional Generative Adversarial Nets [PDF]
arXiv, 2018 Currently, Segmentation of bitewing radiograpy images is a very challenging task. The focus of the study is to segment it into caries, enamel, dentin, pulp, crowns, restoration and root canal treatments. The main method of semantic segmentation of bitewing radiograpy images at this stage is the U-shaped deep convolution neural network, but its accuracy

Journal of Materials Science: Materials in Medicine, 2016 Bone autografts are often used for reconstruction of bone defects; however, due to the limitations of autografts, researchers have been in search of bone substitutes. Dentin is of particular interest for this purpose due to high similarity to bone. This in vitro study sought to assess the surface characteristics and biological properties of dentin ...

Immunohistochemical localization of dentin matrix protein 1 in human dentin
European Journal of Histochemistry, 2009 Dentin matrix protein 1 (DMP1) is a non-collagenous matrix protein with a recognized role in the formation of mineralized tissues such as dentin. The aim of this study was to analyze the distribution of DMP1 in human dentin by means of immunofluorescence

Wntless Regulates Dentin Apposition and Root Elongation in the Mandibular Molar
Journal of dentistry research, 2015 Wnt signaling plays an essential role in the dental epithelium and mesenchyme during tooth morphogenesis. However, it remains unclear if Wnt ligands, produced from dental mesenchyme, are necessary for odontoblast differentiation and dentin formation ...
