In the developing mammalian tooth, the cranial neural crest derived dental mesenchyme consists of the dental papilla and dental follicle. The dental papilla gives rise to odontoblasts and dental pulp and the dental follicle gives rise to the periodontium, including the osteoblasts that contribute to the alveolar process. The alveolar process is a specialized intramembranous bone that forms the ...

The odontogenic fibroma is a rare, benign tumor of mesodermal origin, and one of the most ill-defined and least understood of all odontogenic neoplasms. 1 It presently is thought to originate from either dental follicle, periodontal ligament, or dental papilla. 2 Bhaskar reported the lesion as being the most common odontogenic tumor comprising approximately 23°70 of all odontogenic lesions. 3 T...

Engineering of craniofacial tissues would have a profound impact on various treatment strategies in dentistry. The role of mesenchymal stem cells in the formation of all craniofacial and dental structures has been well demonstrated. Stem cells from various craniofacial structures like dental epithelium, dental follicle, apical papilla, exfoliated deciduous teeth, periodontal ligament and dental...

AIM To investigate the role of Wnt5a in the process of differentiation of human dental papilla cells (HDPCs). METHODOLOGY Recombinant adenovirus encoding full-length Wnt5a cDNA was constructed to investigate the biological role of Wnt5a on the differentiation of HDPCs. The effect of Wnt5a on HDPCs differentiation was determined by ALP activity assay, ALP staining and mineral induction assay. ...

Classification: The following classification is based upon the inductive effect of one dental tissue upon another. In normal tooth development, it has been observed that ameloblastic epithelium exerts an influence upon the undifferentiated mesenchymal cell of the dental papilla "inducing" adjacent cells to further differentiate into odontoblasts. The odontoblasts then begin to form dentine. The...

3 Introduction noticed in whale's tooth by Ploquet in 1794. Salter first described this anatomical anomaly Dens invaginatus is a dental anomaly as “a tooth within tooth” in 1855, and was the which results from invagination of enamel first person who described dens invaginatus in organ into dental papilla, beginning at the 3 ,4 human tooth in 1856. Clinically, a crown and sometimes extending int...

OBJECTIVES The aims of this paper are to review and compare existing techniques for creation of interdental/interimplant papillae, to address factors that may influence its appearance and to present an approach that authors developed that could help clinicians to manage and recreate the interproximal papillae. METHODS Papers related to interdental and interimplant papillae published over the ...

PURPOSE The purposes of this study are to determine if there is a difference in the papilla fill between implant and teeth comparing immediate provisionalized and delayed single tooth implant restorations, and to determine the relationships between the vertical and horizontal bone levels to papilla filling the inter-dental region with single implant restorations. PATIENTS AND METHODS Two grou...

Mesenchymal stem cell-mediated tissue regeneration is a promising approach for regenerative medicine for a wide range of applications. Here we report a new population of stem cells isolated from the root apical papilla of human teeth (SCAP, stem cells from apical papilla). Using a minipig model, we transplanted both human SCAP and periodontal ligament stem cells (PDLSCs) to generate a root/peri...
