Radiopacity evaluation of calcium aluminate cement containing different radiopacifying agents.

Introduction: The aim of this study was to evaluate the radiopacity of calcium aluminate cement (EndoBinder) with 3 different radiopacifiers (bismuth oxide, zinc oxide, or zirconium oxide) in comparison with gray mineral trioxide aggregate (GMTA), white MTA, and dental structures (enamel and dentin).

Methods: Eighteen test specimens of each cement with thicknesses of 0.5, 1.

In vitro comparison of the radiopacity of cavity lining materials with human dental structures.

Aim: To compare the optical densities (OD) of calcium hydroxide (CH) and glass ionomer cement with the same thicknesses of the dental structures.

Materials And Methods: Eighteen specimens of each material, with thicknesses of 0.5, 1.

Surgical repositioning of traumatically intruded permanent incisor: case report with a 10-year follow up.

This report describes the case of a 10-year-old boy that was referred to the pediatric dentistry clinic 15 days after sustaining a severe traumatism that led to complete intrusion of the maxillary left mature permanent central incisor. The intruded tooth was repositioned by using surgical extrusion. Endodontic therapy was performed with calcium hydroxide-based paste as root canal dressing and root canal filling was performed with a calcium hydroxide-based root sealer and gutta-percha points.

Impact of the bitewing radiography exam inclusion on the prevalence of dental caries in 12-year-old students in the city of Franca, São Paulo, Brazil.

Introduction: The pattern of development of carious lesions has changed. The carious lesion has been progressive and reaches the dentin without showing alterations in the clinical aspects.

Objectives: To determine the prevalence of caries in 12-year-old students in the city of Franca - São Paulo, Brazil, during the year of 2003, and to evaluate the additional value of bitewing radiograph to detect hidden carious lesions in permanent molar dentin.

Radiographic evaluation of dental implants with different surface treatments: an experimental study in dogs.

Purpose: The aim of the study was to radiographically measure the bone density at the peri-implant region after osseointegration and to compare the relative bone density achieved by different surface-treated implants.

Materials And Methods: Four different types of implant surfaces were compared, using five young-adult male mongrel dogs. The first, second, third, and fourth lower premolars were extracted.

Growth of cell populations of the intralobular duct in the submandibular gland of the mouse during postnatal development.

The growth of cell populations of intercalated ducts (ID), striated ducts (SD) and convoluted granular tubules (CGT) of the submandibular gland of the mouse was analyzed, during the period of 14 to 84 days of postnatal life, by means of morphometric methods. The absolute number of cells in each type of duct was submitted to curve fitting by means of linear regression analysis, and the obtained equations were: y = 13.22 + 0.
