title: Antifungal activity of components used for decontamination of dental prostheses on the growth of Candida albicans

description: Introduction:The effectiveness of antimicrobial solutions employed in dental prosthesis decontamination is still uncertain.Aim: To evaluate the antifungal activity of cleaners used in the decontamination of dental prostheses on the growth of Candida albicans.Material and method: The evaluated products were: Corega Tabs(r) (S1), Sodium Hypochlorite 1% (S2), Sodium Bicarbonate 1% (S3), Hydrogen Peroxide 1% (S4), Chlorhexidine Digluconate 0.12% - Periogard (r) (S5), Mouthrinse based on essential oils - Listerine(r) (S6), essential oil from Rosmarinus officinalis (rosemary) at concentrations of 1% (S7) and 2% (S8). The antifungal activity of the products was evaluated by agar diffusion technique and the determination of microbial death curve of samples of C. albicans (ATCC 90028) in concentration 1.5 × 106 CFU/mL. The tests were performed in triplicate and statistical analysis was made by ANOVA Two-Way and Tukey tests, with the confidence level of 95%.Result:The average of the zones of inhibition growth, in millimeters, obtained for the products were: 0.0 (S1), 44.7 (S2), 0.0 (S3), 21.6 (S4), 10.0 (S5), 6.1 (S6), 0.0 (S7) and 2.4 (S8). Considering the determination of microbial death curve, all products showed a statistical difference (p&lt;0.01) from control (0.85% sodium chloride) and S3 groups. Fungal growth less than 2×104 CFU/mL and an accentuation of the microbial death curve were observed after 30 minutes, with exception for S3 and control groups.Conclusion:The studied compounds, with the exception of Sodium Bicarbonate, have antifungal effect against C. albicans, which contribute for dental prostheses hygiene.

title: Subjective assessment of the acceptability of cone beam computed tomography images for the planning of osseointegrated implants

description: Introduction: Performing accurate measurements for osseointegrated implant requires that the tomographic images show a minimum quality to allow adequate visualization of anatomical structures.Objective: Therefore, the acceptability of images of different Cone-Beam Computed Tomography (CBCT) protocols was assessed subjectively for the planning of osseointegrated implantsMaterial and method: CBCT images of ten hemimandibles macerated in K9000 3D system were obtained, and only mA was modified (Group I: 2mA, Group II: 8mA and Group III: 15mA). All acquisitions were made with 80kV, FOV of 5 × 3.7 cm, matrix: 512 × 512 and voxel thickness of 0.076 mm. After the acquisitions, the orthogonal reconstructions were analyzed in three voxel sizes by three evaluators, thus making up nine experimental groups . Following bone height and thickness measurements, the evaluators scored (as yes or no) the acceptability of the images to be measured.Result:The groups presented acceptable image quality for implant planning, with the exception of the images acquired with 2mA and analyzed with voxel of 0.076 mm and 0.535 mm.Conclusion:The 8mA and 2.1 mm voxel protocol should preferably be indicated in the identification of the mandibular canal, as the radiation dose is lower than 15mA protocols and image quality is higher than 2 mA protocols. Additionally, 2.1 mm voxel showed a higher acceptability of images.

title: Failure of dental implants in cemento-osseous dysplasia: a critical analysis of a case

description: Introduction: Osseointegrated dental implants have been routinely used in oral rehabilitation. Patients with dysplastic bone diseases represent a particular challenge for oral rehabilitation with dental implants. Nevertheless, the installation of implants in patients with cemento-osseous dysplasia (COD) has been reported with apparent success.Objective: In this paper, we present a case of a patient with COD in which a dental implant had been installed and lost six months later. In this regard, we analyzed pertinent aspects of the indications for dental implants in patients with COD considering the pathogenesis, dysplastic nature, and behavior of the disease.Conclusion:The present case report illustrates that COD can be considered a limiting factor in the recommendation for a dental implant. Because of this, it is imperative to inform the patient about the risks of surgically manipulating the diseased bone.

title: Radiographic examination of patient's initial care in a Brazilian Dental School

description: INTRODUCTION: For X-rays offer more benefits than risks, they need to be performed or ordered according to each clinical situation.OBJECTIVE: To evaluate the radiographic exams requested in the initial care in a dental school, considering signs/symptoms and the reported reasons for seeking care.MATERIAL AND METHOD: We evaluated the medical records of 3100 adult patients treated over a period of three years, and eliminated those who had not performed radiographic examinations in the initial care. In a final sample of 1567 records, was collected: age and gender, reason for seeking care, presence of signs and/or symptoms, beyond technique and the number of radiographs requested. The dates were analysed by descriptive statistics.RESULT: 5034 radiographs were made, mean of 3.24 (±2.97) per patient. Among the techniques, the most widely used was the periapical, followed by panoramic. Tooth extraction and pain were the most prevalent reasons for seeking care, while pain, periodontal disease and the presence of soft tissue pathologies were the signs/symptoms more common. 35.41% of the sample had no signs or symptoms.CONCLUSION: There is a wide variation in the request of radiographs for initial care showing a lack of application of criteria in the selection diagnostic imaging, which can lead to unnecessary exposure to radiation X.
