The aim of this study was to evaluate the mean of alveolar bone loss (%) in radiographies of patients referred to specialist for periodontal treatment. Full mouth series of periapical radiographies (paralelism technique) were used. A total of 9808 proximal surfaces in 4804 teeth of 213 patients (90 males and 123 females), mean age, 44.3 years, were assessed. The alveolar bone loss was measured in relation to root lenght expressed as an average similar to Schei 's technique (1959) without the use of ruler. The references used were the distances cement-enamel juntion (CEJ) - alveolar crest (AC) and CEJ- dental apex taken with a digimatic caliper. The results showed that the mean values of alveolar bone loss (%ABL) was 22.39%. Men showed higher mean values of %ABL than women; the %ABL increased with the age, but the difference among age groups was no statistical significant (p>0.05); the mean values of %ABL of distal surfaces was higher than mesial surfaces (p<0.01), ríght quadrants exhibited higher %ABL values than left quadrants (p<0.01); maxillary sites showed mean values of %ABL higher than mandibular sites; the highest mean values of %ABL was found in molar group, followed by incisor groups, and premolar group; the canine group exhibited lower mean values of %ABL; the differences among the groups was considered statitistically significant (p<0.01). lt was suggested the usage of this technique in the dentistry offices and radiological services for the patient 's documentation and assortment and for later comparison about alveolar bone level

One of the complications that concern prosthetists is bone loss peri-implant, because the success of dental implant treatment requires long-term maintenance of hard and soft tissues around the implant. Whereby the dental implants have not only the goal of restoring function, but also the aesthetics of the patient, the bone loss peri-implant can dramatically compromise the aesthetics of rehabilitation, particularly in anterior regions. The aim of this study was to analyze and reason, through literature review, the main factors that can cause bone loss in peri-implant and possible ways to prevent it.

This study evaluated the potential of congenital transmission in goats experimentally infected and reinfected with Toxoplasma gondii, in three gestational stages (initial, intermediate and final). Of the 25 non-pregnant females negative for T. gondii, 20 were orally inoculated with 2.5 x 103 T. gondii ME49 oocysts. Of these, 15 pregnant females chronically infected were reinoculated, via oral, with 2.5 x 103 T. gondii VEG oocysts. Five experimental groups were formed (n=5): I, II and III (reinoculations in the initial, intermediate and final gestational stage, respectively), IV (inoculation) and V (no inoculation). Clinical and serological exams (IgG IFAT [indirect immunofluorescence antibody test]) in different days of evaluation, and bioassay and PCR were performed in all goats. In the infected goats with T. gondii a peak of 40.2°C (IV) at nine, seroconversion (IgG≥64) at 21 and stabilization (IgG<1024) at 119 days postinoculation were observed. In the reinfected goats with T. gondii occurred an increase in IgG titers (≥1,024) at 28 (I), 7 (II) and 3 (III) days post-reinoculation. During kidding were observed only in the reinfected groups: dystocia, malformation body, stillbirth and weakness, and IgG anti-Toxoplasma were detected in all and in some offsprings of the reinfected and infected goats, respectively. Tissue parasitism by T. gondii was diagnosed by bioassay and PCR in infected and reinfected goats and in their offspring. The congenital toxoplasmosis was possible in goats chronically infected and reinfected with T. gondii. The primary infection with T. gondii did not protect the pregnant goats against congenital disease resulting from toxoplasmic reinfection, in different gestational stages (initial, intermediate and final).

This study had the aim of verify the perception of women and pregnant women about the HIV vertical transmission. It was approved by the Ethical Review Board. A semistructured questionnaire, pretested, was used, with open and closed questions which presented variables about socioeconomiccultural status and HIV vertical transmission. After informed consent, 114 women were enrolled in the study, 72 of them pregnant women, who looked for health care on the public health service of a Brazilian city, at São Paulo State, from October, 2009 to January, 2010. None of the interviewed women knew the meaning of HIV vertical transmission term. When asked about HIV transmission from mother to child, 86.8% answered it could happen, but half of them didn’t know how it occurred and only 34.2% knew how to prevent, but in a deficient way. As conclusion, these women did not know the HIV vertical transmission term and when they had some knowledge this was limited. These results serve as support for a preventive program for conscientization of women about HIV vertical transmission.

Among the harmful health agents, it is given to the noise, one of the most present in urban and social environments. There are efficient measures to control the noise and the auricular Individual Protection Equipment (IPEa) is the most used. It has been observed the shortage in the comfortable and functional individual auditory protection products, related to durability, face to the efficiency right of the equipment. The main objective of this study was to recognize if there is effectiveness loss toward the used time on the Auditory Equipment, intra-auricular Individual Protection, of foam (3M), model 1110. It has been verified that the equipments suffer efficiency alteration according to the time of use, and the material consuming initiates reliable loss, mainly in audible frequencies going up to 100Hz, and from 16 days for sonorous pressure suffered started in 101dB 20Hz. For sonorous pressure suffered from 107dB to 20Hz, the reliable loss for the usage was of 8 days. The IPEas do not lose effectiveness on important attenuation by the daily use in frequencies from 1KHz until 20KHz. It has been concluded that there is effectiveness loss, according to the daily and frequent use of the IPEa studied.
