Avaliação da desadaptação das selas de próteses parciais removíveis após 1 a 5 anos de uso

The non-adaptation of the removable partial prosthesis (RPP) base to fibromucosal tissue is caused by resorption of residual ridges (RRR). The onset of bone resorption, which occurs after tooth extraction and continues throughout life, is accelerated by local or systemic factors. Aim: Assess the degree of non-adaptation of removable partial prosthesis saddles and the factors that influence it. Methodology: A sectional study was conducted with 81 patients using RPP who had their prostheses installed between 2003 and 2007 (1 to 5 years of use) at the Faculty of Dentistry of the Universidade Federal do Rio Grande do Norte (UFRN). After anamnese and clinical examination, a cast was made with polyether-based material, using the base of the prosthesis to make the impression. The base of the saddle was loaded with the casting material and positioned in the mouth, applying pressure on the supports. After polymerization, the material was removed from the saddle and measurements were taken at 3 different points using a pachymeter. Results: The non-adaptation of the saddle increased significantly with years of use (p = 0.005). The tooth-tissue supported prostheses obtained higher mean non-adaptation values than those of tooth supported prostheses (p < 0.001). Flaccid mucosa showed the worst non-adaptation results, which were statistically different from resilient mucosa (p < 0.001). The greater the extension of the saddle, the greater the non-adaptation (p < 0.001). The natural tooth antagonistic arch yielded better results than did RPP and total prosthesis (p < 0.001). Saddle non-adaptation at the free end was less near the pillar tooth and greater in the more posterior region (p < 0.001). When adaptation of the supports to the niches was poor, greater saddle non-adaptation occurred than when it was good or fair (p < 0.001). Saddles located in the posterior region of the arch had greater non-adaptation than those in the anterior region (p = 0.023). Conclusion: The mean non-adaptation of the saddle to the residual ridges was 0.27 mm. It can be concluded that, even with the use of RPP, bone height reduction was slight within the 1-5-year period of use. The following are factors that influence adaptation of the RPP saddle base: years of use, age, force transmission path to the alveolar bone, location of the toothless area, antagonistic arch, type of mucosa, adaptation of supports to the niche and extension of the saddle

APPLICATION OF WISDOMS PERTURBATIVE METHOD TO THE 5/2 AND 7/3 RESONANCES

Wisdom's perturbative method is applied to the 5:2 and 7:3 resonances. Some comparisons with Yoshikawa's model are performed: for values of eccentricity up to about 0.3-0.4, agreement exists and it is better for 5:2 resonance. A clear difference between the cases 5:2 and 7:3 is observed : the former one, like in the case 3:1, can show significant variations of eccentricity, even starting from very small values, close to zero, while the latter seems to undergo such variations, but with initial eccentricity not less than a value near 0.1.

Retardo na procura do tratamento odontológico e percepção da saúde bucal em mulheres grávidas

The objective was to assess in women with children under 5 years old what happened to your pregnancy in relation to dental care, coupled with a probable correlation between the level of their knowledge on dental health and possible reasons which lead or have led to a late seeking such treatment. The interviews were conducted in an environment of health center in the city center and the Odontoly Faculty in Araraquara. Among the interviews mothers, 57% refused the dental treatment during pregnancy. It appears on mothers that are afraid to perform a dental treatment during pregnancy. The misinformation on this issue often associated with this belief in the medical field that dental care during the first three months of pregnancy is harmful to the baby. Such information passed on to mothers leads to a hesitancy with dental treatment during this period. The educational level of mothers did not interfere in this pursuit, and 24.5% of them avoid treatment during pregnancy. The difference, however, is between those mothers of high educational level, performing oral prevention before pregnancy.

Formação docente e o ensino da educação física junto às crianças com 6 anos de idade no 1º ano do ensino fundamental: a perspectiva dos professores de educação física

Since there are few physical education teachers working in kindergarten, now, due to the elementary school for nine years - getting children 6 years of age, this seems to be a challenge for teachers. Therefore, interested in mobilizing efforts to understand how your training is on this new context, and how is this entry of students from 6 years old in elementary school. From the perspective of the physical education teacher who is acting in this context. In this sense, the objective of this study was to analyze teacher training and teaching of physical education among children 6 years of age entering the first grade of elementary school from the perspective of physical education teachers who work in this field. This study was guided by the principles of qualitative research, making the collection through semi-structured interview, 11 participated in the investigation of physical education teachers working in the first grade of elementary school. The categories of analysis that have emerged from our study were: 1 Teacher training; 2 The 9-year elementary school for children 6 years of age; 3 Teaching physical education in early childhood education: Reflections on its limits and its possibilities. We can point out that physical education in school is still recognized as unimportant, although the LDB 9394/96 art. 26 § 3, have given your requirement, this is not enough to change the scenario that presents itself. School is still considered by many as a space in which the body is separated from the cognitive. Therefore, for many, the play of children is worthless and physical education is worthless. Teachers interviewed here reveal that has focused efforts on making a better quality of physical education, especially among children 1 year, trying to meet their expectations and need characteristics of the universe of childhood

Application of Wisdom's perturbative method for 5 : 2 and 7 : 3 resonances

Wisdom's method is applied to 5 : 2 and 7 : 3 resonances. Comparisons with Yoshikawa's nontruncated model are performed: for moderate values of eccentricity, agreement is good, especially for the 5 : 2 resonance. A clear difference between the 5 : 2 and the 7 : 3 resonances is observed: the former (like the 3 : 1 resonance) can suffer significant variations of eccentricity, even starting from very small values close to 0, while the latter seems to undergo such variations but the minimum eccentricity cannot be less than a value near 0.1. In the 7 : 3 resonance, some chaotic motion trapped in a region of very small eccentricity is possible. This is in contrast with the 5 : 2 commensurability, since chaos in this case seems to be always related to significant variations of eccentricity. Recent calculations performed by Šidlichovskÿ using mapping techniques show agreement with the results presented here. © 1992.

Phase contrast and time-of-flight magnetic resonance angiography of the intracerebral arteries at 1.5, 3 and 7 T

Time-of-flight (ToF) and phase contrast (PC) magnetic resonance angiographies (MRAs) are noninvasive applications to depict the cerebral arteries. Both approaches can image the cerebral vasculature without the administration of intravenous contrast. Therefore, it is used in routine clinical evaluation of cerebrovascular diseases, e.g., aneurysm and arteriovenous malformations. However, subtle microvascular disease usually cannot be resolved with standard, clinical-field-strength MRA. The purpose of this study was to compare the ability of ToF and PC MRA to visualize the cerebral arteries at increasing field strengths.
