Is cone beam computed tomography accurate for postoperative evaluation of implants? An in vitro study.

Objective: The aim of this study was to evaluate the accuracy of cone beam computed tomography (CBCT) for evaluation of the bone-implant interface in comparison with periapical radiography.

Study Design: Titanium implants were inserted in 74 bovine rib blocks in intimate contact with bone walls and with a gap of 0.125 mm (simulating failure in the osseointegration process).

Imaging evaluating of the implant/bone interface-an in vitro radiographic study.

Objectives: To analyze the diagnostic accuracy of conventional and digital radiographic images and the impact of digital filters in evaluating the bone-implant interface.

Methods: Titanium implants were inserted into 74 fresh bovine ribs blocks, 37 fitting tight to the bone walls (simulating the existence of osseointegration) and 37 with a gap of 0.125 mm (simulating a failure in the osseointegration process).

Enamel surface evaluation after bracket debonding and different resin removal methods.

Objective: To assess enamel surface under scanning electron microscopy (SEM) after resin removal and enamel polishing procedures following brackets debonding, as well as compare the time required for these procedures.

Methods: A total of 180 deciduous bovine incisors were used. The enamel surface of each tooth was prepared and brackets were bonded with light cured Transbond XT composite resin.

Calcitonin: a non-invasive giant cells therapy.

This paper reports four cases of central giant cell granuloma (CGCG) treated with calcitonin, attesting the efficacy and safety of its use as the chosen therapy for large CGCG. Four patients presenting CGCG treated with calcitonin were included in this study. Salmon calcitonin was administered for 6-28 months.
