Auto-transplantation is the repositioning of an autogenously erupted, partially erupted, or unerupted tooth from one site to another in the same individual. The purpose of this case report is to describe the auto-transplantation of the mandibular third molars as an alternative means of replacing second molars requiring extraction. An orthopantomogram revealed horizontal impaction of teeth #37 and 47 and mesio-angular impaction of teeth #38 and 48. Cone beam computed tomography revealed that the roots of #37 and 47 were in close proximity to the inferior alveolar canal bilaterally...

Dentigerous cysts are the most common developmental odontogenic cysts of the jaw, which usually occur in the second and third decade of life. It is most frequently associated with impacted mandibular third molar teeth and impacted canines. Bilateral/multiple dentigerous cysts are rare and typically associated with developmental syndromes. Non-syndromic dentigerous cyst occurring bilaterally or involving both arches at the same time is very rare. Here, we discuss the review of literature with a case of unusual occurrence of non-syndromic bi-maxillary dentigerous cysts in a child...

White adipose tissue is a source of mesenchymal stromal/stem cells (MSCs) that are actively studied for their possible therapeutic use in bone tissue repair/remodeling. To better appreciate the osteogenic potential of these cells, we compared some properties of MSCs from human subcutaneous adipose tissue [subcutaneous-adipose stromal cells (S-ASCs)] and dental pulp stem cell (DPSCs) of third-impacted molars, the latter representing a well-established MSC source. Both undifferentiated cell types showed similar fibroblast-like morphology and mesenchymal marker expression...
