Evaluation of hollow fiberoptic tips for the conduction of Er : YAG laser

Objective: The use of Er:YAG laser operating in the 3 μm range with adjustable power and pulses has become popular for dental and medical practice due to its high photoablative capacity, surgical precision and antimicrobial action. Background data: The existing fiberoptic tips irradiate lasers parallel to the long axes of the tooth limiting its efficiency in the root canal. Methods: We evaluated hollow fiberoptic tips obtained from silicate glass as a means of Er:YAG laser conduction in dental procedures. The fiber tips were molded from capillary tubes with different profiles so that their ends would have cylindric, conical or spherical shapes. The performance of the three fibers as a means of propagation of Er:YAG (λ = 2.94 μm) laser radiation was compared to that of a solid sapphire fiber at 10 Hz and 200 mJ and of 20 Hz and 500 mJ. The profiles of frontal and lateral burning were visualized on thermal paper. Results: Analysis of these profiles demonstrated that the sapphire tip and the hollow fiber of cylindric section did not differ significantly in the profiles of frontal burning, and no lateral burning was detected. The fibers of the conical and spherical sections, although presenting attenuation in the frontal output power, showed a larger burning area in the frontal profile, in addition to producing lateral burning. Conclusions: The results indicate that commercial hollow fiberoptics have advantages such as easy manufacture of the different tip shapes, great adaptability, low cost, and a low loss of transmission. © Mary Ann Liebert, Inc.

Utilização dos arcos seccionados para o tratamento da má oclusão de classe II, divisão 2

A má oclusão de Classe II divisão 2 é caracterizada pela verticalização dos incisivos superiores. Nesse tipo de má oclusão, é comum a presença de sobremordida profunda e curva de Spee inferior acentuada. O presente artigo ilustra que o tratamento dessa má oclusão pode ser facilitado com o emprego dos arcos seccionados, como por exemplo, o arco utilidade, segundo a técnica Bioprogressiva de Ricketts.

Study on Chagas disease occurrence in the municipality of Monte Negro, State of Rondônia, Brazilian Amazon

Introduction: Studies on Chagas disease deal with the perspective of its occurrence in the Amazon region, which is directly correlated to the population growth and the spread of the bug biotope. The state of Rondônia has an immense source of vectors (Triatomine) and reservoirs of Trypanosoma cruzi. Environmental changes brought forth by the deforestation in the region may cause vector behavior changes and bring these vectors to a closer contact with humans, increasing the probability of vector infection. Methods: This study was carried out to check the occurrence of Chagas disease in the municipality of Monte Negro, Rondônia, Brazil, based on a random sampling of the farms and people wherein blood collection from the population and capturing triatomines were done. The blood samples were submitted to serologic tests to detect antibodies of the IgG class against T. cruzi. The triatomines that were collected had their digestive tract checked for the presence of trypanosomatidae with morphology resembling that of the T. cruzi. Results: The population examined was mostly from other states. From the 322 bugs examined on the microscope, 50% showed parasites with morphology compatible with T. cruzi. From the serology of 344 random samples of human blood, 1.2% was found positive, 6% showed inconclusive results, and 92.8% were negative. Conclusions: Monte Negro shows low prevalence of human infection by T. cruzi and none active vector transmission; however, preventive and surveying measures, which are not performed until now, shall be taken due to the abundance of vectors infected by trypanosomatidae.

A semiose peirceana no jornalismo colaborativo online

The purpose of this article is to think the online collaborative journalism from the perspective of semiosis in Charles Sanders Peirce. It seeks to define the formal elements of language hypermedia web, beyond the concepts of semiosis, sign, object and interpretant. Thus, paths are indicated for understanding how different aspects of the news can emerge and coexist in mediating the journalistic own website, marked by the decentralization of the production and dissemination of media content, as opposed to mediation system based on broadcast journalism. There is also a small survey of the evolution of Brazilian collaborative journalism on the web, showing that there is still a tendency to keep the logic of journalism massive unidirectional.

Realidade interativa: protótipo de telejornal interativo para TV Digital baseado no conceito de infotretenimento

The goal of this article is to describe the production of “Interactive Reality” program, prototype for interactive Digital TV newscast based on the concept of infotainment, defined as a genre hybrid television show between information and entertainment. Therefore, it is proposed a script with interactive content, a prototype of the newscast, its results and implications for future researches.
