Título: Mortalidade por câncer de boca e faringe em Natal/RN no período de 1981 a 1995 Autor(es): Almeida, Maria Eneide Leitão de Abstract: This is an epidemiological time tendency study about the mortality of mouth and pharynx câncer on the population of the city of Natal, from 1981 to 1995. Many considerations were taken about the main risk factors for these types of câncer and their epidemiological situation. We intended to analyze comparatively the relation among the tendency of mortality caused by mouth and pharynx câncer and the other neoplasias within the established period. The data were collected from the obituary of the dead citizens of Natal from 1981 to 1995 by means of the Mortality Information System of Rio Grande do Norte, available in CD-ROM, and also from the demographic censi of 1980 and 1991. In order to organize the analisis, the data were divided into consecutive groups of three years (Triennium) and the main variables were sex, age and the anatomical sites attacked by the câncer. The potential years of life lost (PYLL) due to the occurrence of mouth and pharynx câncer were also estimated and recorded. The results showed that in the first trienium (1981-83), the risks of dying in Natal decreased from 756.93 to 630.96 per 100,000 men and from 528.01 to 417.00 per 100,000 women. Nevertheless, considering the mouth and pharynx câncer, these rates assumed and ascending aspect, raising from 2.60 to 6.66 among men and from 1.55 to 2.08 among the women. The proportional mortality rate (%) caused by malignant neoplasias in the last triennium (1993-95) was 12.4% among men and 16.9% among the women, showing a clear ascending tendency throughout the studied period. The most common anatomical sites, in men and women, attacked by the malignant neoplasias of the mouth (not especifíed) and the average of ages was from 65 to 69 years old. There was a significant subtration of 1,167.5 potential years of life from the population of the city of Natal, and 977.5 years were taken from the men and 190.0 from the women. Tipo: Dissertação

Título: Avaliação, através da microscopia eletrônica de varredura, da limpeza de canais radiculares instrumentados pela técnica manual, ultra-sônica ou combinação de ambas, coadjuvadas por alguns agentes irrigadores Autor(es): Pinto, Sérgio Araújo Holanda Abstract: The purpose of this work is to evaluare the root canal preparation effectiveness of hand and ultrasonic instru mentation techniques and hand technique followed by final ultra sonication with a smooth instrument, as well the effects or irrj_ gations Solutions such as Tergentol, Milton and Endo-PTC. Ninety recently extracted human canines were used for this study. In hand instrumentation, thirty teeth were instru mented by the step-back technique, having a file = 40 as a memory and file = 60 as final instrument. In the ultrasonic instrumen- tation trhity teeth were instrumented inicially with a file = 15 and then, the preparation was made by = 1 5, = 20, = 25 , uj_ trasonically energized K-type files during 1,5 minute each one. In the hand/u1trasonic technique thirty teeth were treated like those in the hand preparation group, except that an ultrasoni- cally energized smooth instrument was used following completion of hand technique for one minute. At the end preparation, the teeth were 1ongitudina 1ly sectioned and prepared for scanning electron microscope analysis. Tipo: Dissertação

Título: Estudo cefalométrico radiográfico das características crânio-faciais em pacientes com síndrome da apnéia do sono obstrutiva Autor(es): Chaves Júnior, Chaves Júnior, Cauby Maia Abstract: The present study evaluated by means of cephalometric measurements a group of 44 male patients, brazilian caucasians, aged 20 to 64 years old (mean age:44,3 1 10,2), with polysomnographic diagnosis of OSA. The purpose of this study was to identify the craniofacial characteristics, (skeletal and soft tissues), and its possible association with clinicai and polysomnographic findings that contribute to airway obstruction in OSA patients. The sample was divided in two groups of 22 patients, according to their Apnea - Hipopnea Index (AHI). The first group had an AHI<50 (sleep apnea mild or moderate). The second group had an AHI>50 (severe sleep apnea). We also divided these 44 patients according to their body mass index (BMI).Twenty one patients had BMI<29 (normal or mild obesity) and 23 patients had BMI>29 (moderate or morbid obesity).
