Combined Effects of Puerarin and Adipose‐Derived Stem Cells on Alveolar Bone Preservation and Inflammation Control in Periodontitis Through p38MAPK Modulation

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study evaluated the effects of puerarin and adipose‐derived stem cells (ADSCs), alone or combined, on p38MAPK activity, alveolar bone preservation, and inflammatory responses in a rat periodontitis (PD) model and in vitro. ADSCs were exposed to various puerarin concentrations to assess cell proliferation, osteogenic differentiation, and ...

Three-dimensional anatomy of equine incisors : tooth length, enamel cover and age related changes [PDF]

open access: yes, 1944
BACKGROUND:Equine incisors are subjected to continuous occlusal wear causing multiple, age related changes of the extragingival crown. It is assumed that the occlusal wear is compensated by continued tooth elongation at the apical ends of the teeth.

Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

open access: yesVIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Consumption of anthropogenic foods influences the nutritional and reproductive condition of hunter‐harvested black bears

open access: yesWildlife Biology, EarlyView.
The consumption of human food subsidies influences ecological processes, and can affect individual behavior and fitness with population level changes in abundance and distribution. American black bears Ursus americanus often consume human food subsidies, which have been correlated with increased bear body size, age‐specific fertility and mortality ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

open access: yesHigh Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Incremental lines in root cementum of human teeth: An approach to their role in age estimation using polarizing microscopy

open access: yesIndian Journal of Dental Research, 2008
Age estimation is an important factor in the identification of an individual in forensic science. The hard tissues of the human dentition are able to resist decay and degradation long after other tissues are lost.

Association of Maxillofacial Fractures With Demographic and Dental Factors: The Roles of Edentulism, Posterior Occlusion, Canines, and Lower Third Molar

open access: yesDental Traumatology, EarlyView.
ABSTRACT Background/Aim This retrospective, two‐center study aims to improve understanding of fracture pathogenesis in maxillofacial trauma by examining variations related to sex, age, dental status, posterior occlusion, and the presence of lower third molars (LTM) and lower canines.
