Restoration of lost interdental papilla remains one of the most challenging goals for clinicians. When a single tooth is replaced with an implant, the papilla between the tooth and the implant can often be maintained or predictably reconstructed as long as the periodontal attachment and bone of the adjacent tooth is preserved. However, if the periodontal support is compromised on the neighborin...

Fungiform papillae are epithelial taste organs that form on the tongue, requiring differentiation of papillae and inter-papilla epithelium. We tested roles of epidermal growth factor (EGF) and the receptor EGFR in papilla development. Developmentally, EGF was localized within and between papillae whereas EGFR was progressively restricted to inter-papilla epithelium. In tongue cultures, EGF decr...

OBJECTIVE Dermal papilla and hair epithelial stem cells regulate hair formation and the growth cycle. Damage to or loss of these cells can cause hair loss. Although several studies claim to reconstitute hairs using rodent cells in an animal model, additional research is needed to develop a stable human hair follicle reconstitution protocol. In this study, we have evaluated hair induction by inj...

Abstract The interdental papilla is of utmost importance in smile aesthetics. Missing tissue often raises an aesthetic concern; however, the issue more than just complication. This study reviews most commonly seen cases and methods to minimize complications caused by missing tissue. technique that will be discussed from nonsurgical techniques, including composite restoration, indirect restorati...

The volumes of the dermal papilla, matrix and fully grown hair of vibrissal follicles of rats and mice were measured. Dermal papillae were surgically removed from rats' vibrissal follicles and a small new dermal papilla was always reformed. The lower third of rats and mice follicles, containing the whole of the dermal papilla was amputated and very small dermal papillae were reformed. Follicles...

AIM The purpose of the present study was to describe and evaluate a new incision technique: the papilla base incision. METHODOLOGY Twenty healthy patients referred for surgical treatment of persisting apical periodontitis, who were free of periodontal disease and had intact interdental papillae were included in the study. The preoperative papilla height was recorded by measuring the distance ...

Dens invaginatus is a rare developmental malformation resulting from an alteration in the normal growth pattern of the dental papilla. Teeth in both maxillary and mandibular arches may be affected, but the permanent maxillary lateral incisors are the most frequently involved teeth. The invagination ranges from slight accentuation of a lingual pit to an anomaly occupying most of the crown and ro...

Several case reports on endoscopic resection of minor papilla adenomas exist in the literature. However, there are no reported cases of endoscopic resection in patients with minor papilla adenomas with associated familial adenomatous polyposis (FAP) and pancreas divisum. We report a case of a minor papilla adenoma in a patient with FAP and pancreas divisum. The case demonstrates a new associati...

BACKGROUND AND STUDY AIMS Endoscopic papillectomy is currently used to treat noninvasive tumors of the papilla of Vater, but it is seldom reported for treatment of similar tumors of the minor papilla. This report describes the case of a 69-year-old female with a tumor located at the duodenal minor papilla. Findings of duodenoscopy, biopsy, and pancreatography indicated that her noninvasive tumo...
