objective: the aim of the present study was to histopathologically evaluate follicular tissues of third molars with pericoronal radiolucenciesof less than 2 millimeters. materials and methods: in this descriptive analytic study, 100 impacted third molars with normal follicular spaces were removed and their pericoronaltissues submitted for histopathologic examination. different characteristicsof...

BACKGROUND Tooth root problems and periodontal diseases are common in South American camelids (SAC). The objective was to evaluate and optimize the imaging technique for dental radiography in SAC and to describe the radiographic and computed tomographic (CT) anatomy of normal teeth at different ages. In this study, the heads of 20 healthy SAC slaughtered for meat production or euthanized for re...

Background  Wisdom teeth are usually removed as a routine procedure for therapeutic or prophylactic reasons. Developing wisdom teeth are easy accessible source of stem cells during the adulthood which could be obtained. Methods  Search of the PubMed for stem cells and tooth was done. An inclusion criterion was extract of stem cells from wisdom tooth. Results  Stem cells can be obtained fro...

PURPOSE The aim of this study was to compare the bonding strength, flexural strength, elastic modulus, water absorption and the expansion after water storage of new self-adhesive resin cements to commercially available dental cements. METHODS Two types (hand-mix and auto-mix) of new self-adhesive resin cements (SAC-H and SAC-A, Kuraray Medical), one conventional resin cement (Panavia F2.0), t...

Cone beam CT, usually used in dental area, could easily obtain 3-dimensional images using cone beam shaped ionized radiation. Cone beam CT is very useful for direct percutaneous sac injection (DPSI) which needs very precise measurement to avoid puncture of inferior vena cava or vessel around sac or stent graft. Here we describe two cases of DPSI using cone beam CT. In case 1, a 79-year-old male...

dental tissues provide an alternate source of stem cells compared with bone marrow and have a similar potency as that of bone marrow derived mesenchymal stem cells. it has been established there are six types of dental stem cells: dental pulp stem cells, stem cells from human exfoliated deciduous teeth, stem cells from apical papilla, periodontal ligament stem cells, dental follicle progenitor ...

Enlarged follicles associated with multiple unerupted teeth always comprise an area of considerable interest for oral and maxillofacial surgeons. The condition of multiple calcifying hyperplastic dental follicles is extremely rare and is characterized by multiple unerupted teeth with abundant calcifications and odontogenic epithelial rests in the enlarged dental follicles. We report an interest...

This paper introduces a new kind of local consistency based on the general idea of singleton arc consistency (SAC). This is a reduced form of SAC that only considers neighbourhoods of a variable with a singleton domain; hence, the name “neighbourhood SAC” (NSAC). Like AC and SAC, NSAC has a unique fixpoint, so that NSAC algorithms will produce the same result when applied to a problem regardles...
