Background: Valvar heart disease is an important public health problem, more common in developing countries, especially in younger.Objective: To evaluate the epidemiological features of patients and its influence on the prosthesis type choice used on patients who underwent valve surgery.Methods: Cross-sectional. Data such as age, sex, provenance, surgery procedure and prosthesis type were retrospectively analyzed. We reviewed 366 charts of all patients submitted to heart valve surgery during three years in a public health cardiovascular treatment center.Results: 52% of patients were female. The age range was from 5 to 82, the median was 41 years old. In regards 37.7% of patients came from Salvador (Bahia, Brazil) and 62.3% from countryside. Valve replacement was performed in 73% of patients, whereas 7.38% underwent valvuloplasty and 18.3% underwent valve repair and replacement. Regarding type of prosthesis, 70.0% received bioprosthesis and 30.0% received metal prosthesis. On note bioprosthesis were more used in younger (66 vs. 14; P<0,001).Conclusion: Biological prostheses were used predominantly in younger. This might be possible due to a low social-economic status, avoiding metal valve implantation and the consequent anticoagulation therapy. Descriptors: Heart valve diseases. Prosthesis implantation. Socioeconomic factors.Resumo Introdução: A doença cardíaca valvar é um grave problema de saúde pública, mais frequente em países em desenvolvimento, acometendo indivíduos em idade laboralmente produtiva.Objetivo: Avaliar o perfil socioeconômico e RBCCV 44205-1373

ObjectiveTo evaluate the influence of the type of prosthesis in-hospital mortality in the post-operative period in patients who had valve replacement.MethodsA cross-sectional data, such as gender, origin, age, etiology, echocardiograph data, the type of surgery performed and the prosthesis used in cases of valve replacement were analyzed retrospectively.ResultsWe reviewed 353 charts of patients who underwent valve replacement surgery. The mean age was 41.87±17.9 years. Regarding gender, 52.8% were female. As for the origin, 61.1% came from small cities within the state. Of all patients, 58.5% suffered from rheumatic disease. Assessing the type of prosthesis implanted, 70% held replace by bioprosthesis and 30% metallic. The hospital mortality in this study was 11%, with no significant difference between the types of prosthesis utilized.ConclusionThe type of implant used had no effect on in-hospital mortality.

Biological prostheses were used predominantly in younger. This might be possible due to a low social-economic status, avoiding metal valve implantation and the consequent anticoagulation therapy.

The present in vitro study aims to evaluate cytotoxic and genotoxic potential of MTA Fillapex endodontic sealer and to compare it with AH Plus sealer. It was used human fibroblast cell lines FG11 and FG15 for this study. Cytotoxicity and genotoxicity was analysed in human gingival fibroblast submitted to growth condition with MTT test conditioned cells, respectively. Cells cultivated in DMEM means was used as command. Celular viability was mensured in 24, 48 and 72h. Results was analysed by the software Biostat 4.0 Shapiro-Wilk normality test was made but sample presented non-normal behavior. Descriptive analysis was made and its results was submitted to Kruskal-Wallis test (Dunn). All sealers and control groups presented MTT values lower in 24h period than 48 and 72h (p<0.05). The biggest cell viability was observed in AH Plus sealer and in control group related to MTA Fillapex in all experimental periods (p≤0.0002). In terms of genotoxicity, the biggest value was mensuared in AH Plus sealer in the 24h period with significantly difference compared to MTA Fillapex and the control group (p=0.0004). It may be concluded that MTA Fillapex sealer showed higher cell cytotoxicity than two control groups and AH Plus sealer presented higher genotoxicity than other groups.

The anatomical complexity of the root canal system is an ongoing challenge for the endodontist. The morphology of the permanent maxillary first molar contains numerous variations regarding the number of roots and canals. Thus, the success of endodontic treatment is related to the domain of anatomy. The aim of this study is to present a case report on a maxillary first molar with seven root canals.A 17-year-old female patient, melanoderm, was seen at the multidisciplinary clinic for a routine examination. In the clinical examination, a extensive carie was found in element 14. Radio graphically, radiolucent area was observed circumscribing the root apexes of this dental element. The following steps were performed. Anesthesia with 2% lidocaine, access surgery, absolute isolation and irrigation with 2.5% sodium hypochlorite. With the aid of ultrasonic vibration with an E7D insert at a frequency of 30 kHz for 20 seconds, connected to a piezoelectric device, the pulp chamber floor was refined. After this procedure it was found, through the exploration of a 10 K file and magnification with operative microscope, atypical anatomy with extra canals: mesiobuccal canal 1, mesiobuccal canal 2, vestibular mesio 3, distobuccal 1, distobuccal 2, palatine 1 and palatine 2.Cervical third preparation was performed with the aid of a Logic 25/05 rotary instrument, confirmation of working length with foraminal locator, apical third preparation and intracanal medication insertion: calcium hydroxide. Soon after the consultation, a computed tomography was requested to confirm the root canals. In the second session, after removal of intracanal medication, rotary files were recapitulated, 2.5% sodium hypochlorite irrigation, final irrigation with agitated EDTA with 25 IRRS ultrasound insert and thermoplastic obturation.The dental element was restored and a new CT scan was requested for follow-up. In this context, it can be concluded that the dental surgeon must be aware of the anatomical diversity, thus avoiding failures. The patient remains asymptomatic and dental element performing its functions.
