ObjectivesThe aim of this study was to evaluate the detection of enamel-dentin occlusal caries using photostimulable phosphor plates. Material and MethodsThe ability to detect enamel-dentin occlusal caries in 607 premolars and molars from 47 patients between 10 and 18 years old, referred to the School of Dentistry of the Federal University of Bahia, Brazil, was evaluated based on clinical and radiographic examinations, using the criteria proposed in a previous study. A total of 156 bitewing digital images were obtained using Digora® (Soredex Medical Systems, Helsinki, Finland) phosphor plates. The plates were scanned and the images were captured and displayed on a computer screen. Image evaluation was done using Digora® for Windows 2.1 software, Soredex®. The radiologists were allowed to use enhancement tools to obtain better visibility during scoring of the teeth based on the radiographic criteria proposed in a previous study. Descriptive analysis and chi-squared proportion tests were done at 5% significance level. ResultsThe results of clinical examination showed a higher prevalence of teeth with a straight dark line or demineralization of the occlusal fissure (score 1) and a lower prevalence of sealed teeth (score 5). In the bitewing digital images, 47 teeth presented visible radiolucency, circumscribed, in dentin under occlusal enamel (enamel-dentin caries lesions). ConclusionsCorrelating the clinical and radiographic findings, it was found that in the majority of teeth diagnosed by radiographic images as having enamel-dentin caries, no caries could be detected by clinical examination.
Objectives: To evaluate variables associated with the need of denture by patients with special needs attending the Dental Specialty Center (DSC) in Poá, São Paulo, Brazil. Materials and methods: The total sample consisted of 514 patients, treated at the DSC-Poá, and the dependent variable was need of denture established between January 2011 and December 2016. The analyzed variables were gender, age, main diagnosis, amount of medication used, and behavioral aspects. The physical records were compiled to an electronic form specially developed for this study. Data were tabulated and analyzed. Results: Eighty-eight patients (17.11%) were referred to prosthetic rehabilitation. The female gender prevailed and the need for denture increased with age, in a similar manner as in the general population. Main diagnosis was a relevant variable, with the majority (47.72%) presenting systemic alterations, followed by physical deficiency (18.18%) and psychiatric disorders (11.36%). Regarding the behavior, all individuals were attended as outpatients, the majority (71.59%) had already received anesthesia in previous treatments, and only 7.95% required psychological conditioning. Most of the patients with special needs (89.77%) came to receive and use the prostheses. Conclusions: Main diagnosis and behavioral profile variables influenced the denture indication for those patients at the DSC-Poá. Gender and age also influence indication, as seen in the general population. This study may guide the implementation of projects both in private and public sectors.
Objective: To evaluate the perceptions of students aged 05-12 years about dentists through the interpretation of drawings. Material and Methods: This is a crosssectional study whose sample consisted of 1015 children aged 5-12 years from 10 public schools of Salvador, Brazil. The students produced drawings about their main idea associated with the dentist and answered a semi-structured interview consisting of seven items. Results: Males (521 volunteers -51.3%) were more prevalent than females (494 volunteers, 48.6%), 688 (67.7%) children had experienced dental care, and need for treatment was the reason for seeking dental care to 306 (30.1%) of them. In describing the professional using one word, positive words totaled 805 (79.1%) responses, negative words accounted for 24 (2.2%) and 186 (18.3%) participants could not answer. The drawing category that had the largest number of volunteers was "Procedures", with 238 (23.4%) drawings, followed by: "Dental Consultation" with 228 (22.4%), "Other Professionals" with 174 (17.1%), "Dentist" with 115 (11.3%), "Oral Health" with 71 (6.9%), "Miscellaneous" with 71 (6.9%), "Dental Office" with 55 (5.4%), "Mouth" with 36 (3.5%) and "Pain / Fear" with 27 (2.6%). Conclusion: Drawings were effective in representing the particular vision of students and showed a plurality and complexity of concepts and ideas related to the dentist. In addition to procedures and consultation, professional behavior, knowledge transmitted to patients, physical environment and experienced sensations, factors linked to the origin of the main idea about the professional were also relevant. The perception of volunteers was positive both in the drawings as in the responses of the semi-structured interview.
