Permian bolosaurid parareptiles are well-known for having complex tooth crowns and complete tooth rows in the jaws, in contrast to the comparatively simple teeth and frequent replacement gaps in all other Paleozoic amniotes. Analysis of the specialized dentition of the bolosaurid parareptiles Bolosaurus from North America and Belebey from Russia, utilizing a combination of histological and tomographic data, reveals unusual patterns of tooth development and replacement. The data confirm that bolosaurid teeth have thecodont implantation with deep roots, the oldest known such example among amniotes, and independently evolved among much younger archosauromorphs (including dinosaurs and crocodilians) and among synapsids (including mammals)...

This is a case report of a 14-year-old female patient in whom a premolar from a donor was used as an allotransplant to replace her missing lower premolar. The treatment results over 6 months showed successful periodontal healing and functioning of the allotransplanted tooth. The aim of this paper is to report a procedure, allotransplantation of tooth, which is followed from ages but less preferred and documented and is surrounded by variable prognosis and also highlight the use of a intentionally extracted tooth for orthodontic purpose, which otherwise goes as a waste and moreover the use of this technique can supplement the need of an implant for the time being in the young patient without compromising her alveolar bone height, functioning, and esthetics...

Introduction: Hall technique (HT) is a biological approach where decay is sealed under preformed metal crowns without any caries removal, tooth preparation or local anesthesia. Dental caries is one of the most common prevailing chronic condition that affect both adults and children. Since children are anxious and apprehensive to dental treatment, their uncooperative behavior might cause hindrance in the treatment, which often leads to manage them in general anesthesia. To better address the dental care needs in pediatric patients, dental surgeons require some alternatives for management of caries and restorative treatment in children...

Epithelial signaling centers control epithelial invagination and organ development, but how these centers are specified remains unclear. We report that Pitx2 (the first transcriptional marker for tooth development) controls the embryonic formation and patterning of epithelial signaling centers during incisor development. We demonstrate using Krt14 Cre / Pitx2 flox/flox ( Pitx2 cKO ) embryos, and Rosa26 CreERT /Pitx2 flox/flox mice that loss of Pitx2 delays epithelial invagination, decreases progenitor cell proliferation, and dental epithelium cell differentiation...

Vitamin D (VD) levels have been gaining growing attention in Oral Health. During growth and adulthood, VD deficiency (VDD) is associated with a wide variety of oral health disorders, and impaired VD synthesis may expedite some of these conditions. In children, severe VDD can induce defective tooth mineralization, resulting in dentin and enamel defects. As a consequence, these defects may increase the risk of the onset and progression of dental caries. Further, VDD has been associated with higher prevalence of periodontitis and gingival inflammation, and several recent preclinical and clinical studies have unveiled potential pathways through which Vitamin D may interact with the periodontium...
