Assessment of enamel-dentin caries lesions detection using bitewing PSP digital images

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% 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

Uso de próteses removíveis em pacientes com necessidades especiais: risco associado ao diagnóstico

Objetivos: Avaliar variáveis associadas à necessidade do uso de prótese dos pacientes com necessidades especiais (PNE) do Centro de Especialidades Odontológicas da Estância Hidromineral de Poá (CEO-Poá). Materiais e métodos: A amostra total foi composta por 514 PNE do CEO-Poá, e a variável dependente foi a necessidade de uso de prótese estabelecida entre janeiro de 2011 e dezembro de 2016. As variáveis foram gênero, idade, diagnóstico principal, quantidade de medicação utilizada usualmente e aspectos comportamentais e foram compiladas do prontuário físico para o formulário eletrônico desenvolvido para este estudo. Dados foram tabulados e analisados. Resultados: Foram encaminhados 88 indivíduos (17,11%) à reabilitação protética. Prevaleceu o gênero feminino e o avanço da idade aumentou a necessidade de uso de prótese, de forma semelhante à população geral. O diagnóstico principal foi uma variável influenciadora, a maioria (47,72%) apresentou alterações sistêmicas, seguido de deficiência física (18,18%) e distúrbios psiquiátricos (11,36%). Quanto ao comportamento, todos indivíduos foram atendidos em âmbito ambulatorial, a maioria (71,59%) já havia recebido anestesia em tratamentos anteriores, e apenas 7,95% precisou de condicionamento psicológico. Grande parte dos PNE (89,77%) chegou a receber e utilizar as próteses. Conclusões: O diagnóstico principal e variáveis do perfil comportamental foram influenciadores na necessidade de próteses dos PNE do CEO-Poá. Gênero e idade igualmente influenciam a indicação, assim como na população em geral. Esse estudo poderá nortear a implementação de projetos tanto no setor privado como no público.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
