RÉSUMÉ

Objetivo: Comparar la discrepancia anteroposterior medida a nivel de la platina incisiva de 2 métodos de registro intermaxilar en la misma sesión que la im-presión definitiva en adultos mayores desdentados totales. Materiales y métodos. Se incluyeron en el es-tudio 20 pacientes (n=20) con edad promedio de 70 años. En cada uno de ellos se obtuvieron registros intermaxilares con cubetas rodete de acrílico: uno con inducción manual (IM) y otro autoinducido con el sistema de cubeta rodete de acrílico y apoyo central único utilizando una superficie palatina de registro curva (BYC). Los modelos fueron montados en un ar-ticulador Whip Mix modelo 2240 al que se le adicio-nó un dispositivo de papel milimetrado, Orthodent, a nivel de la platina incisiva, para registrar las dife-rencias existentes entre las posiciones obtenidas. El análisis estadístico se llevó a cabo mediante el cálcu-lo de intervalos de confianza (95%) para las diferen-cias medias y prueba de t de student para datos apa-reados (nivel de significancia: α<0,05). Resultados. En el plano mesiodistal a nivel de la platina incisiva se encontró diferencia estadísticamente significativa entre las dos variables de registro (p<0,001). A este nivel el BYC proporcionó registros más retrusivos que IM. Media aritmética (desviaciones estándar) en milímetros: 3,82 (2,1). Conclusión. El sistema de re-gistro con cubetas rodete acrílicas y BYC incorpora-do a las mismas proporciona un registro intermaxi-lar más retrusivo que IM en adultos mayores des-dentados totales cuando se realizan dichos registros en la misma sesión que la impresión definitiva (AU)


Objective: To compare the anteroposterior discre-pancy measured at the level of the incisal plate of 2 methods of intermaxillary registration in the same session as the definitive impression in fully edentu-lous older adults. Materials and methods. Twenty pa-tients (n=20) with an average age of 70 years were included in the study. On each of them, intermaxillary recordings were obtained with acrylic rims trays: one with manual induction (MI) and the other with a self-induced system and single central support using a curved recording palatal surface (BYC). The models were mounted in a Whip Mix model 2240 articula-tor to which an Orthodent graph paper device was added, at the level of the incisal plate, to record the di-fferences between the positions obtained. Statistical analysis was carried out by calculating confidence intervals (95%) for mean differences and T-student for paired data (significance level: α<0.05). Results. On the mesiodistal plane at the level of the incisal plate, a statistically significant difference was found between the two recording variables (p<0.001). At this level the BYC provided more retrusive recordings than MI. Arithmetic mean (standard deviations) in mi-llimeters: 3.82 (2.1). Conclusions. The registration system with acrylic rim trays and BYC incorporated into them provides a more retrusive intermaxillary registration than MI in fully edentulous older adults when such registrations are made in the same ses-sion as the final impression.(AU)

RÉSUMÉ

Objetivou-se avaliar a influência da suplementação com minerais biocomplexados sobre a qualidade da carne de frangos da linhagem Label Rouge, de ambos os sexos, criados em sistema alternativo. O delineamento experimental foi inteiramente ao acaso (DIC), disposto em esquema fatorial (3x2), sendo três dietas (controle; 0,50ppm de selênio; 0,40ppm de cromo) e dois sexos. Para a estabilidade lipídica, foi utilizado o DIC, disposto em esquema fatorial (3x2x2), sendo três dietas, dois sexos e dois tempos de armazenamento (zero e 12 meses). Os parâmetros avaliados no peito e na coxa foram: pH final, cor (L* - luminosidade, a* - índice de vermelho, b* - índice de amarelo, C* - índice de saturação e h* - ângulo de tonalidade), perda de peso por cozimento (PPC), força de cisalhamento (FC) e estabilidade lipídica. Além disso, foram avaliadas a proporção das formas químicas da mioglobina da coxa e a quantificação do conteúdo de selênio no peito. Não houve efeito isolado da dieta sobre os parâmetros físicos e químicos do peito e da coxa e sobre a concentração de selênio no peito. As fêmeas apresentaram médias superiores de L* (57,57), b* (10,55) e C* (10,60) do peito; e os machos de L* (55,09) da coxa. Entre os machos, as aves alimentadas com a dieta controle e com cromo expressaram valores superiores de FC da coxa em relação às suplementadas com selênio; para o tratamento com cromo, os machos apresentaram média superior de FC da coxa e, em contrapartida, para o tratamento com selênio, as fêmeas manifestaram a maior média. As amostras submetidas ao período de 12 meses de armazenamento mostraram maiores valores de substâncias reativas ao ácido tiobarbitúrico (TBARS) em ambos os cortes. A suplementação com cromo e selênio biocomplexados não provocou alterações na qualidade da carne; as fêmeas demonstraram melhores atributos de qualidade da carne.(AU)


The objective of the present study was to evaluate the influence of the supplementation with biocomplexed minerals on the quality of the meat of label Rouge lineage chicken, of both genders, reared in an alternative system. The experimental design was completely randomized (CRD) in a factorial scheme (3x2), with three diets (control; 0.50ppm of selenium; 0.40ppm of chromium) and two genders. For lipid stability, the CRD arranged in a factorial scheme (3x2x2) was used, being three diets, two genders and two storage times (0 and 12 months). The parameters evaluated in the breast and in the thigh were: final pH, color (L* - luminosity, a* - red index, b* - yellow index, C* - saturation index and h* - tonality angle), weight loss per cooking (WLC), shear force (SF) and lipid stability. In addition, we evaluated the proportion of chemical forms of myoglobin of the thigh and the quantification of selenium content in the breast. There was no isolated effect of diet on the physical and chemical parameters of the breast and thigh and selenium concentration in the breast. Females had higher mean values of L* (57.57), b* (10.55) and C* (10.60) of the breast; and males of L* (55.09) of the thigh. Among males, poultry fed with the control diet and chromium showed higher SF values of the thigh than those supplemented with selenium; for the treatment with chromium, the males presented superior average of SF of the thigh and, in contrast, for the treatment with selenium, the females had the highest average. Samples submitted to the period of 12-month of storage showed higher values of substances reactive to thiobarbituric acid (TBARS) in both cuts. Supplementation with biocomplexed chromium and selenium did not cause changes in meat quality; females presented better attributes of meat quality.(AU)
