Este artigo tem por objetivo apresentar as ações desenvolvidas na construção do modelo de atenção em saúde no Distrito Especial Indígena - Xingu (DSEI-Xingu), mais especificamente, na área de saúde bucal, com a efetiva parceria entre a Universidade Federal do Estado de São Paulo (UNIFESP), Faculdade de Odontologia de Ribeirão Preto - Universidade de São Paulo (FORP-USP) e a Colgate®, que permitiu a construção social da práxis em saúde no Médio e Baixo Xingu. Ao longo da história, o DSEI "Espaço Social" é onde as comunidades se constituem e, por meio do processo social de produção, cria acessos diferenciados aos bens de consumo, além de formar a base para a organização dos serviços de atenção à saúde dos povos indígenas. Para o DSEI-Xingu, são pontos básicos o estabelecimento de parcerias institucionais e a participação efetiva dos povos indígenas na gestão da saúde em seu território. Estruturado no planejamento baseado em problemas sentidos pela população, utiliza-se da construção coletiva de redes explicativas, apontando soluções em vários planos com abordagem intersetorial. É através da observação dos indicadores de saúde que se torna perceptível a assimilação das comunidades indígenas com o recente modelo de atenção básica à saúde bucal, uma vez que constantemente está sendo adaptado à cultura, à tradição e às singularidades desses povos indígenas.

Prosthetic restorations that have been tried in the patient's mouth are potential sources of infection. In order to avoid cross-infection, protocols for infection control should be established in dental office and laboratory. This study evaluated the antimicrobial efficacy of disinfectants on full metal crowns contaminated with microorganisms. Full crowns cast in a Ni-Cr alloy were assigned to one control group (n=6) and 5 experimental groups (n=18). The crowns were placed in flat-bottom glass balloons and were autoclaved. A microbial suspension of each type of strain - S. aureus, P. aeruginosa, S. mutans, E. faecalis and C. albicans- was aseptically added to each experimental group, the crowns being allowed for contamination during 30 min. The contaminated specimens were placed into recipients with the chemical disinfectants (1% and 2% sodium hypochlorite and 2% glutaraldehyde) for 5, 10 and 15 min. Thereafter, the crowns were placed into tubes containing different broths and incubated at 35ºC. The control specimens were contaminated, immersed in distilled water for 20 min and cultured in Thioglycollate broth at 35ºC. Microbial growth assay was performed by qualitative visual examination after 48 h, 7 and 12 days. Microbial growth was noticed only in the control group. In the experimental groups, turbidity of the broths was not observed, regardless of the strains and immersion intervals, thus indicating absence of microbial growth. In conclusion, all chemical disinfectants were effective in preventing microbial growth onto full metal crowns.

OBJECTIVE: The aim of the present study was to determine the in vitro maximum inhibitory dilution (MID) of two chlorhexidinebased oral mouthwashes (CHX): Noplak®, Periogard®, and one polyhexamethylene biguanide-based mouthwash (PHMB): Sanifill Premium® against 28 field Staphylococcus aureus strains using the agar dilution method. MATERIALS AND METHODS: For each product, decimal dilutions ranging from 1/10 to 1/655,360 were prepared in distilled water and added to Mueller Hinton Agar culture medium. After homogenization, the culture medium was poured onto Petri dishes. Strains were inoculated using a Steers multipoint inoculator and dishes were incubated at 37ºC for 24hours. For reading, MID was considered as the maximum dilution of the mouthwash still capable of inhibiting microbial growth. RESULTS: Sanifill Premium® inhibited the growth of all strains at 1/40 dilution and of 1 strain at 1/80 dilution. Noplak® inhibited the growth of 23 strains at 1/640 dilution and of all 28 strains at 1/320 dilution. Periogard® showed inhibited growth of 7 strains at 1/640 dilution and of all 28 strains at 1/320 dilution. Data were submitted to Kruskal-Wallis statistical test, showing significant differences between the mouthwashes evaluated (p<0.05). No significant difference was found between Noplak® and Periogard® (p>0.05). Sanifill Premium® was the least effective (p<0.05). CONCLUSION: It was concluded that CHX-based mouthwashes present better antimicrobial activity against S. Aureus than the PHMB-based mouthwash.

The aim of this study was to evaluate the anticaries potential of 500 or 1100 ppm F dentifrices combined with fluoride varnish using a pH-cycling regimen. Seventy primary canines were covered with nail polish, leaving a 4×4 mm window on their buccal surface, and randomly assigned into 7 groups (n = 10): S: sound enamel not submitted to the pH-cycling regimen or treatment; N: negative control, submitted to the pH-cycling regimen without any treatment; D1 and D2: subjected to the pH-cycling regimen and treated twice daily with 1100 or 500 ppm F dentifrice, respectively; VF: fluoride varnish (subjected to F-varnish before and in the middle of the pH-cycling regimen); and VF+D1 and VF+D2. After 10 days, the teeth were sectioned, and enamel demineralization was assessed by cross-sectional hardness at different distances from the dental surface. Data were analyzed using a two-way ANOVA followed by Tukey's test. Dentifrice with 1100 ppm F and the combination of F-varnish with the dentifrices significantly reduced enamel demineralization compared with the negative control (p < 0.05), but the isolated effects of F-varnish and dentifrice with low concentration were not significant (p > 0.05). The effect of combining F-varnish with the dentifrices was not greater than the effect of the dentifrices alone (p < 0.05). The data suggest that the combination of F-varnish with dentifrices containing 500 and 1100 ppm F is not more effective in reducing demineralization in primary teeth than the isolated effect of dentifrice containing 1100 ppm F.

O objetivo deste estudo foi coletar dados sobre a prevalência e severidade de gengivite em uma amostra de crianças em idade escolar, bem como sua relação com possíveis fatores de risco locais. Duzentos e seis indivíduos foram examinados, sendo 107 meninos e 99 meninas, com idades entre 7 e 14 anos; foram coletados dados referentes ao índice de placa (IP), índice gengival (IG) e profundidade clínica de sondagem (PCS). Entre os parâmetros clínicos observados, as médias referentes a PCS, IP e IG encontradas foram de 1,58 + 0,46, 1,12 + 0,49 e 0,89 + 0,32, respectivamente. Noventa e cinco indivíduos (46,1%) apresentaram um quadro de gengivite leve e 111 (53,9%), de gengivite moderada. No geral, os indivíduos do sexo masculino apresentaram estatisticamente maior quantidade de placa bacteriana e maior inflamação do tecido gengival que indivíduos do sexo feminino. A presença de inflamação gengival foi encontrada em todos os indivíduos examinados. A severidade de inflamação nos dentes permanentes esteve diretamente relacionada à quantidade de placa e ao sangramento à sondagem.

A simple and low cost method to determine volatile contaminants in post-consumer recycled PET flakes was developed and validated by Headspace Dynamic Concentration and Gas Chromatography-Flame Ionization Detection (HDC-GC-FID). The analytical parameters evaluated by using surrogates include: correlation coefficient, detection limit, quantification limit, accuracy, intra-assay precision, and inter-assay precision. In order to compare the efficiency of the proposed method to recognized automated techniques, post-consumer PET packaging samples collected in Brazil were used. GC-MS was used to confirm the identity of the substances identified in the PET packaging. Some of the identified contaminants were estimated in the post-consumer material at concentrations higher than 220 ng.g-1. The findings in this work corroborate data available in the scientific literature pointing out the suitability of the proposed analytical method.
