Can non-collagenous proteins be employed for the differential diagnosis among fibrous dysplasia, cemento-osseous dysplasia and cemento-ossifying fibroma?

Differential diagnosis among fibrous dysplasias, cemento-ossifying fibromas and cemento-osseous dysplasias is difficult, since there is considerable overlap of histologic features, but also extremely important, since they differ greatly in etiology, clinical behaviour, prognosis and terapeuthic approach. There is no data about the use of immunohistochemistry, a viable and accessible technique, for this purpose. The objective of this study was to investigate, comparatively, the immunohistochemical expression of major non-collagenous proteins (osteonectin [ON], osteopontin [OP], bone sialoprotein [BSP] and osteocalcin [OC]) of mineralized tissue extracellular matrix in 22 cases of fibrous dysplasias, 16 of cemento-ossifying fibromas and 16 of cemento-osseous dysplasias.

How much does household food insecurity explain income inequalities in untreated dental caries?

Background: The pathway by which socioeconomic disadvantages are manifested in the occurrence of dental caries remains unclear.

Aim: To explore how much the association between untreated dental caries and income inequalities is related to household food insecurity (HFI).

Design: A population-based study was conducted with a sample of 466 12-year-old students.

Glass Ionomer Cements can be used for Bonding Orthodontic Brackets After Cancer Radiation Treatment?

Patients undergoing radiotherapy treatment present more susceptibility to dental caries and the use of an orthodontic device increases this risk factor due to biofilm accumulation around the brackets. The objective of this study was to evaluate the shear bond strength to irradiated permanent teeth of orthodontic brackets bonded with conventional glass ionomer cement and resin-modified glass ionomer cement due to the fluoride release capacity of these materials. Ninety prepared human premolars were divided into 6 groups (n=15), according to the bonding material and use or not of radiation: CR: Transbond XT composite resin; RMGIC: Fuji Ortho LC conventional glass ionomer cement; GIC: Ketac Cem Easymix resin-modified glass ionomer cement.

Consequences of Facial Hemangioma with Regard to Dental Treatment.

Hemangioma is a benign vascular tumor that affects 3%-10% of the population and usually does not require specific treatment due to spontaneous regression. The purpose of this paper is to present a case report of a child having been born prematurely and diagnosed with hemangioma in the head and neck, emphasizing the dentofacial changes and treatment used to provide care. Severe fibrous scars were found in the perioral region and below the ear that limited the patient's ability to open her mouth.
