RESUMEN

Objetivo: Avaliar o nível de conhecimento dos cirurgiões-dentistas especialistas de João Pessoasobre fotografia digital. Material e Métodos: Tratou-se de um estudo observacional e prospectivo com amostragem não probabilística. A amostra foi composta por 60 profissionais inscritos no Conselho Regional de Odontologia da Paraíba (CRO-PB), nas seguintes especialidades: Prótese, Ortodontia, Dentística e Periodontia. A coleta de dados foi realizada por meio de um questionário, com perguntas objetivas e subjetivas. Os dados foram tabulados em banco de dados e submetidos à análise estatística descritiva. Resultados: Foi possível verificar que a maior parte dos cirurgiões-dentistas são adeptos a utilização da fotografia digital (71,6%) para diversos fins. Dentre as especialidades, a ortodontia obteve o maior percentual (86,6%), seguido da prótese (73,3%), da periodontia (66,6%) e da dentística (60%). Conclusões: A maioria dos especialistas utiliza a fotografia digital como parte da documentação odontológica. Os ortodontistas têm destaque quanto à utilização e frequência das fotografias. Ainda são necessários estudos adicionais para maior aprofundamento sobre o tema em questão.

Objective: This research aimed to evaluate the level of knowledge of specialists dentists in João Pessoa on digital photography. Material and Methods: It was a prospective observational study with non-probability sampling. The sample was composed by 60 professionals enrolled in Regional Council of Dentistry of Paraiba (CRO-PB), in the following specialties: Prosthesis, Orthodontics, Periodontics and Restorative Dentistry. The data collection was performed by means of a questionnaire, with objective and subjective questions. The data were tabulated in a database and submitted to descriptive statistical analysis. Results: It was possible to verify that the greater parts of dentists are adherents to the use of digital photography (71.6 %) for various purposes. Among the specialties, Orthodontics has obtained the highest percentage (86.6 %), followed by Prosthodontics (73.3 %), Periodontics (66.6 %) and Restorative Dentistry (60 %). Conclusions: The majority of specialists use digital photography as part of the dentistry documentation, with orthodontists being the specialists that most commonly uses it. Although additional studies are necessary to further deepening on the topic in question.

RESUMEN

In this study poly(lactic acid) (PLA) and polyvinylpyrrolidone (PVP) micro- and nanofiber mats loaded with Copaiba (Copaifera sp.) oil were produced by solution blow spinning (SBS). The Copaiba (Copaifera sp.) oil was characterized by gas chromatography (GC). Neat PLA and four PLA/PVP blends containing 20% (wt.%) oil were spun and characterized by scanning electron microscopy (SEM) and by studying the surface contact angle, in vitro release rate, and antimicrobial activity. All compositions evaluated were able to produce continuous and smooth fibers by SBS. The addition of PVP increased fiber diameter, and decreased the surface contact angle. GC analysis demonstrated that the main component of the Copaiba oil was ß-caryophyllene, a known antimicrobial agent. In vitro release tests of Copaiba oil volatiles demonstrated a higher release rate in fibers containing PVP. Fiber mats made from blends containing higher amounts of PVP had greater antimicrobial action against Staphylococcus aureus. The results confirm the potential of the fiber mats for use in controlled drug release and could lead to promising applications in the biomedical field.

RESUMEN

BACKGROUND: Dementia, a syndrome characterised by multiple cognitive impairments, is an increasing medical and social problem across the world. The Mini-Mental State Examination (MMSE) is the instrument most often used in the evaluation of cognitive compromise and dementia in elderly individuals. It is noteworthy that there is a scarcity of works in the literature on the dimensions of the MMSE and its relation to dental variables in the elderly. OBJECTIVES: To evaluate the condition of cognitive impairment, the dimensions of the MMSE, and the latter's relation to socio-demographic and dental variables in elderly individuals of Montes Claros, Minas Gerais, Brazil. MATERIAL AND METHODS: This is a cross-sectional descriptive study, whereby 218 elderly users of the system were evaluated at the Sistema Único de Saúde (Brazilian health service) in Montes Claros. The collection of data involved the realisation of structured interviews and clinical dentistry examinations. The screening of cognitive impairment was carried out with the Portuguese version of MMSE. The data were subjected to descriptive and bivariate analyses. RESULTS: The prevalence of cognitive impairment found was 6.4%. A statistically significant association was observed between cognitive decline and age, marital status and use of dental prostheses. An association was also noted between several dimensions of MMSE and edentulism (time orientation, attention and calculation, and final score) and use of prostheses (except evocation memory and language). CONCLUSIONS: It was noticed that those who were 80 years old or more, not married and using prostheses were more likely to manifest cognitive impairment. Associations between some MMSE dimensions were established, including the final score, with edentulism and the use of prostheses.
