This study was designed to determine if the following two variables influence the predictability of the presence of the interproximal papilla between single implant supported crown adjacent to a natural tooth: a) the vertical measurement from the crest of bone on the natural tooth to the contact point, and b) the horizontal measurement from the platform of the implant to the adjacent tooth root...

The purpose of this study was to evaluate the morphological structure of palatal rugae in Turkish orthodontic subjects with different sagittal skeletal malocclusions. Orthodontic dental casts of 105 patients (Class I [23 females, 12 males]; 35, Class II [18 females, 17 males]; and 35, Class III [14 females, 21 males] 10-22 years old) were analyzed for rugae patterns. Palatal rugae pattern and n...

This study seeks to understand the effects of new hydrogels based on Oregano® essential oil, Frankincense® and Thieves® blend, which includes clove, lemon, cinnamon bark, eucalyptus radiata, rosemary extract, oil through in vitro cytotoxicity antimicrobial analysis. Mesenchymal stem cells (D1MSCs) generated from dental papilla human wisdom teeth germs were used test hydrogels’ (D1MSCs). The che...

Papilla and skin are two important organs of the sea cucumber. Both tissues have ectodermic origin, but they are morphologically and functionally very different. In the present study, we performed comparative transcriptome analysis of the papilla and skin from the sea cucumber (Apostichopus japonicus) in order to identify and characterize gene expression profiles by using RNA-Seq technology. We...

The ampulla ureter and ampulla urogenital ⁄ uriniferous papilla represent differing morphologies of the caudal urogenital ducts in snakes. The ampulla ureter is an enlarged portion of the caudal extremity of the ureter that communicates the cranial regions of the ureter and the ductus deferens ⁄Wolffian duct to the urodaeum. The ampulla urogenital ⁄ uriniferous papilla is an enlarged pouch, dis...

Pollination is an important early step in sexual plant reproduction. In Arabidopsis thaliana, sequential pollination events, from pollen adhesion onto the stigma surface to pollen tube germination and elongation, occur on the stigmatic papilla cells. Following successful completion of these events, the pollen tube penetrates the stigma and finally fertilizes a female gametophyte. The pollinatio...

four regions or stages in the life cycle of the odontoblast. The pulpal arteries in the differentiating dental papilla cell region and the pre-odontoblastic region immediately spread into capillaries towards the odontoblastic layer. The capillaries formed a network in the shape of polygonal meshes. The capillary wall appeared to be continuous. In the young odontoblastic region, the capillaries ...

The pluripotent nature of embryonic stem cells (ESCs) makes them amenable for regenerative therapies because they can differentiate into cells that form all tissue types within the body (Zandstra and Nagy, 2001). The potential drawbacks to the use of ESCs for cellular therapies include the obvious ethical dilemmas of obtaining ESCs, the potential of cancer or tumor formation and the risk of imm...

The capacity of lower follicle dermal sheath to restore hair growth was tested by removing the lower halves of follicles, and then immediately implanting material containing dermal sheath cells from these bases, into the remaining upper epidermal follicle cavity. Over 60% of recipient follicles produced stout emergent vibrissa fibres and some operations resulted in multiple hair production from...
