The impact of digital filters on the diagnosis of simulated root resorptions in digital radiographic systems.

Objectives: To evaluate the influence of digital filters of intraoral radiographic systems on the diagnosis of simulated internal and external root resorptions and image quality.

Materials And Methods: Internal root resorption (IRR) and external root resorption (ERR) were simulated in 34 teeth. For image acquisition, two radiographic systems were used: Digora Toto and VistaScan.

The Importance of Ultrasound in Excision of the Buccal Fat Pad.

Partial excision of the buccal fat pad is a surgery indicated for different functional and aesthetic procedures. Although this surgery offers minimal risks, the ultrasound examination can provide security in performing the surgery, in addition to predicting preoperative anatomical variations and assisting in the treatment of postoperative complications. With the worldwide search for aesthetic procedures, concomitant with the development of imaging tests that help in different diagnoses and treatments, ultrasonography has become an excellent indication for planning oral fat pad surgeries.

Ultrasonography and Facial Aesthetics.

Ultrasonography examination is an important ally of facial aesthetic procedures. This examination allows for precise planning, with complete vascular mapping of the face, cutaneous and subcutaneous thickness, in addition to enabling procedures guided by filled substances. The knowledge of this information allows the professional to carry out his work in a safe manner, with reduced chances of complications and clinical failures, combining aesthetics with a satisfactory function.

Assessment of dentists' behaviour on the use of patients' images.

Background: Photographs and radiographs are indispensable resources for dental education, research and dissemination of clinical cases in scientific journals. The objective of this study was to evaluate the behaviour of dentists on the use of patients' images.

Material And Methods: Fifty-two dentists were interviewed using a semi-structured script containing open-ended questions on the use of patients' images.

Intraoral Device for Optimal Antifungal Delivery in a Rat Model.

Background: Antifungal agents incorporated into temporary denture resilient liners as drug carriers and delivery have been suggested as an alternative treatment for denture stomatitis. However, to test the in vivo biocompatibility of this protocol, standardization of an intraoral device for optimal drug delivery is required.

Objective: Standardized criteria were produced to adjust an acrylic intraoral device (IOD) for rats feasible for denture stomatitis treatment by sustained drug-delivery based on minimal inhibitory drug concentrations (MICs) of antifungals for Candida albicans biofilm.
