Life history data derived from the dental histological analysis of Giraffa camelopardalis: Implications for the palaeohistology of extinct giraffids

open access: yesJournal of Anatomy, EarlyView.
The study of incremental lines in the dentine (left), cementum (centre) and enamel (right) of the giraffe revealed key information about the rate and pattern of dental growth in this vertebrate. These results were also useful to obtain data on the biology and life history of the species and sets the stage for future palaeohistological analysis in ...

Palaeohistology and life history of the early Palaeocene taeniodont Conoryctes comma (Mammalia: Eutheria)

open access: yesJournal of Anatomy, EarlyView.
Determining the life histories of mammals after the extinction of the dinosaurs is key to understanding why they rose so quickly to terrestrial dominance. This study analyses growth in a member of a key mammal group that traversed the extinction boundary.

Hidden Markov random field and FRAME modelling for TCA-image analysis [PDF]

open access: yes
Tooth Cementum Annulation (TCA) is an age estimation method carried out on thin cross sections of the root of human teeth. Age is computed by adding the tooth eruption age to the count of annual incremental lines that are called tooth rings and appear in

Validation of clinically related aging models based on enamel wear

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose Physiological and erosive wear reported in clinical studies were reviewed, and in vitro aging models were developed to simulate and compare the effect of aging on human teeth with the review data obtained from clinical studies. Methods A review of clinical studies and randomized clinical trials that quantify enamel wear was performed ...

High‐Frequency Ultrasound for Detecting Periodontal Inflammation: A Preclinical Diagnostic Accuracy Study

open access: yesJournal of Periodontal Research, EarlyView.
This preclinical porcine study evaluated the accuracy of ultrasound (US) for estimating dimensions of inflamed periodontium. Seven periodontal parameters were measured and compared between US, cone‐beam computed tomography (CBCT), and histology. US has excellent/good agreement with histology in estimating bone level/thickness, soft tissue height ...
