Automating Digital Leaf Measurement: The Tooth, the Whole Tooth, and Nothing but the Tooth

Automating Digital Leaf Measurement: The Tooth, the Whole Tooth, and Nothing but the Tooth

Many species of plants produce leaves with distinct teeth around their margins. The presence and nature of these teeth can often help botanists to identify species. Moreover, it has long been known that more species native to colder regions have teeth than species native to warmer regions. It has therefore been suggested that fossilized remains of leaves can be used as a proxy for ancient clima...

Whole Tooth Regeneration Using a Bioengineered Tooth

Clinical measurement of tooth wear: Tooth wear indices

Attrition, erosion, and abrasion result in alterations to the tooth and manifest as tooth wear. Each classification corresponds to a different process with specific clinical features. Classifications made so far have no accurate prevalence data because the indexes do not necessarily measure a specific etiology, or because the study populations can be diverse in age and characteristics. Tooth we...

Estimating Dental Age Using the Pulp/Tooth Perimeter Ratio in Maxillary Canines by Digital Panoramic Radiography

Introduction: Teeth can be used to determine age in forensic medicine if none of the other techniques of identification are appropriate. The researchers used panoramic radiographs from patients referred to Yazd Shahid Sadoughi Dental School to determine age using pulp/tooth perimeter ratio. Methods: In this diagnostic study, 800 panoramic digital radiographs were examined and the age of the pa...

Does wisdom tooth provide tooth germs for tooth regeneration?

Introduction Regenerating a tooth completely in human oral cavity is not achieved by current studies yet. Here, we have conceived a man-induced method to construct a teeth germ which might be used to regenerate a tooth in vivo. This idea was generated by traits of the development of the compound odontoma, a benign tumour of tooth malformation. This is a kind of developmental tooth malformation,...
