Low reproducibility between oral radiologists and general dentists with regards to radiographic diagnosis of caries.

Aim: Early clinical and radiological diagnosis of dental caries is one of the fundamental objectives of clinical dentistry because of the high frequency of the disease and severe complications if caries remains untreated, especially among the elderly and patients with immunodeficiency. Dental panoramic tomography (DPT) is a common radiographic method for evaluating dentition when indicated, especially in an adult population. The aim of this study was to assess the reproducibility of diagnosis between specialists in oral radiology and general dentists with regards to caries lesions based on DPTs of adults.

Function of laminins and laminin-binding integrins in gingival epithelial cell adhesion.

Background: In human gingiva, epithelial cells attach to their adjacent tissues by means of specialized molecular adhesion complexes and a basement membrane. Little is known about the synthesis of adhesion proteins by gingival keratinocytes; we, therefore, studied how cultured immortalized gingival epithelial cells produce laminins and express laminin-binding integrins. We presumed that different laminins and integrins would be involved in the adhesion of gingival epithelial cells.
