ABSTRACT
To evaluate the perceptions of students aged 05-12 years about dentists through the interpretation of drawings.Material and Methods:This is a cross-sectional 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 ôProceduresõ, with 238 (23.4%) drawings, followed by: ôDental Consultationõ with 228 (22.4%), ôOther Professionalsõ with 174 (17.1%), ôDentistõ with 115 (11.3%), ôOral Healthõ with 71 (6.9%), ôMiscellaneousõ with 71 (6.9%), ôDental Officeõ with 55 (5.4%), ôMouthõ with 36 (3.5%) and ôPain / Fearõ 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...

OBJECTIVES: The aim of this study was to evaluate the detection of enamel-dentin occlusal caries using photostimulable phosphor plates. MATERIAL AND METHODS: The 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 percent significance level. RESULTS: The 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). CONCLUSIONS: Correlating 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.

Um dos grandes desafios em diagnóstico por imagens é detectar pequenas modificaçöes nos tecidos mineralizados, antes que se tornem clinicamente evidentes. A radiografia de subtraçäo digital é um método muito sensível, capaz de revelar alteraçöes de densidade de apenas 5 por cento, envolvendo o tecido ósseo na área pesquisada. Uma revisäo da literatura sobre a radiografia de subtraçäo digital em Odontologia mostra as suas possíveis aplicaçöes em Cariologia, Endodontia, Periodontia, Implantodontia e na avaliaçäo e tratamento das desordens da ATM
