Aware that the main objective of endodontic treatment is the removal of microorganisms and the prevention of re-infection inside the root canal, and that the infections are polymicrobial and difficult to eliminate, the biomechanical preparation is essential for disinfection, though it is unable to eradicate all microorganisms. The intracanal medication is used as an adjunct to treatment, reducing the endodontic microbiota, and favoring the repair of periapical lesions. However, this dissertation consists of two papers and it is proposed, through a written review, to examine and discuss the intracanal medications most frequently used at present in endodontics - calcium hydroxide and chlorhexidine. Further, through research, to evaluate the antibacterial effect of biomechanical preparation and a calcium hydroxide based paste containing or not 2% chlorhexidine, as intracanal medication in the treatment of necrotic teeth after trauma, as well as to verify the presence of the microorganisms Fusobacterium nucleatum and black-pigmented bacilli inside the root canal of teeth. According to the inclusion criteria, the sample consisted of 14 incisors necrotic after trauma. The microbiological samples were acquired before (S1) and after biomechanical preparation (S2), after intracanal medication (S3) and 72 hours after removal of medication (S4). Selected at random, eight patients used calcium hydroxide as intracanal medication and six patients the calcium hydroxide based paste containing 2% chlorhexidine. The samples were collected sequentially, inserting three sterile absorbent paper cones with a diameter compatible with the root canal, and after a minute the paper points were removed and placed in a tube containing a reduced transport fluid, and sent to the laboratory for microbiological evaluation. The results were analyzed by the Friedman, Conover-Inman and Kruskal-Wallis tests (p <0.05). Microorganisms were found in 100 % of root canals in the initial samples (S1), while in S2 were detected in only 3 out of the 14 samples (21.4 %), resulting in a reduction in the number of colony forming units, a statistically significant result (p <0.001) between S1 and S2. No statistically significant reduction was observed when comparing S2 with S3, S2 with S4, and S3 with S4, regardless of the medication used. It was found that in S1, there was a predominance of Gram-positive cocci - 8 out of 14 (57.1 %) and Gram-negative cocci - 9 out of 14 (64.3 %). In S2 only Gram-positive bacterial morphotypes were detected, in 3 out of 14 samples (21.4 %) of Gram-positive cocci and 2 out of 14 (14.3%) of Gram-positive bacilli. The microorganisms Fusobacterium nucleatum found in 8 of the 14 samples (57.1%) and the black-pigmented bacilli found in 3 of the 14 (21.4%) of the initial samples, and were found in only one out of 6 (16.1%) samples taken after the use of calcium hydroxide. It was concluded that mechanical preparation of necrotic teeth after trauma, using 2.5% NaOCl, plays its role in significantly reducing the microbiota of root canals, but the calcium hydroxide, or the calcium hydroxide based paste containing 2% chlorhexidine, have a limited antibacterial effect, not being able to prevent the re-growth of bacteria after its use as an intracanal medication.

O objetivo deste trabalho foi validar para o Brasil o Child´s and Parent´s Questionnaire about Teeth Appearance e investigar a percepção e a preocupação devido à fluorose dentária em crianças de 12 anos de idade e nos seus pais. Este estudo foi realizado em duas regiões brasileiras: Piracicaba-SP, com ótimos níveis de flúor nas águas de abastecimento público, e Rafael Arruda-CE, com elevados teores de flúor in natura. O questionário original, que verifica o quanto nos últimos dois meses a criança sentiu-se incomodada, preocupada ou impedida de sorrir devido à aparência de seus dentes, ainda não havia sido validado para nenhuma outra língua que não aquelas em que foi originalmente desenvolvido (inglês e espanhol). Durante a primeira fase do estudo (adaptação semântica), obedeceu-se à seguinte metodologia: tradução, retrotradução, avaliação por um comitê de especialistas e pré-teste com 50 pares de pais/crianças. Na segunda fase (validação do instrumento), 213 crianças foram avaliadas clinicamente para o diagnóstico de fluorose dentária pelo índice de Dean, e responderam, assim como seus pais, ao questionário. Os dados obtidos na segunda fase foram usados para avaliar a confiabilidade (consistência interna e estabilidade temporal) e a validade (de constructo e de critério) do instrumento, utilizando coeficiente alfa de Cronbach, coeficiente de correlação intraclasse e correlação de Spearman. O teste t de Student para amostras independentes foi utilizado para a comparação entre as duas regiões, e o teste t pareado para a avaliação da concordância entre relatos de pais e filhos. Na primeira fase do estudo, nenhuma grande discrepância existiu entre as versões do instrumento (original, traduzida e retrotraduzida), e os ajustes realizados ocorreram mais em função dos níveis diversificados de escolaridade da população-alvo. Buscou-se utilizar vocabulário simples e frases curtas, e o questionário mostrou-se de fácil aplicação e bem aceito, permanecendo com os doze itens/subitens do original. Na segunda fase do estudo, a consistência interna foi aceitável e a estabilidade temporal de moderada a excelente. Houve correlação significativa entre percepção da fluorose moderada e severa e os dados clínicos, e entre percepção da fluorose e preocupações dos indivíduos. Embora os pais de Rafael Arruda-CE tenham tido uma maior percepção da fluorose, o incômodo e a preocupação com a aparência foram maiores em Piracicaba-SP. Pais e filhos tenderam a concordar em seus relatos, porém, quando discordaram, os pais geralmente se mostraram mais incomodados, preocupados e insatisfeitos com a aparência dentária do que as próprias crianças. Conclui-se que a versão brasileira do Child´s and Parent´s Questionnaire about Teeth Appearance é um instrumento válido e confiável para avaliar a percepção da estética dentária de crianças brasileiras e em seus pais. A percepção da fluorose teve um impacto negativo na satisfação com a estética dentária e levou à preocupação.

One of the aims of endodontic treatment is to promote the repair in the periapical region, from technical procedures including chemomechanical preparation, represented by the instrumentation associated to irrigation and aspiration, in addition to filling the root canal system. Thus, in Endodontics several irrigation solutions have been employed with the main functions of dentin walls lubrication, organic matter dissolution, removal of microorganisms and smear layer removal. Sodium hypochlorite is the most used substance, however, it possesses some disadvantages, such as high tissue toxicity. Others irrigation solution alternatives have been proposed, such as chlorhexidine and apple vinegar, which has suitable biocompatibility and ability to remove the smear layer. The root canal filling presents technical objectives, focused on the full sealing of the root canal system, as well as, biological, enabling closure of the apical foramen, through the deposition of mineralized tissue. For many years, gutta-percha associated with a sealer has been used, however, with the advent of adhesive materials in dental clinic, some hit the market with employment in Endodontics, the most known Resilon/Epiphany system. Thus, the objective of this study was to assess, by fluid filtration method, the influence of irrigation solution and the filling materials (cones and sealer) association in the apical root leakage. One hundred twelve lower pre-molars human teeth were instrumented and filled, being initially divided into two controls groups and 8 groups (n = 12), according to the irrigation solution, (H) sodium hypochlorite, (V) apple vinegar, and root canal filling materials, gutta-percha/AH Plus (GA), Resilon/Epiphany (RE), gutta-percha/Epiphany (GE) and Resilon/AH Plus (RA). The results have showed no statistical difference in relation to the irrigation solutions used (p> 0.05), nevertheless, it was found that the groups filled with Resilon/AH Plus (H/RA and V/RA) association had significantly more leakage than the other groups (p <0.05). It was concluded that the apical leakage were influenced only by the filling material regardless the irrigation solution.

The integration of titanium dental implants in bone has been reported extensively over the last few decades beginning with the original work of Branemark and co-workers. The use of titanium endosseous dental implants in the treatment of edentulous or partially edentulous patients has become an alternative to restore function and esthetics, however, this results depend on the quantity and quality of the maxillary or mandibular bone. Osteoporosis is a disease that influences the quality of bone tissue such that it may become susceptible to fracture. Significant relationship have been reported between oral bone and skeletal bone mass in postmenopausal women. Osteoporosis could, therefore be considered a risk factor for osseointegration of dental implants, but this is still controversial. Strontium ranelate is a new therapy for the treatment and prevention of osteoporosis that may dissociate bone formation and bone resorption by allowing continued production of bone while decreasing bone resorption. The purpose of this study was to determine the effect of systemic strontium ranelate therapy on early dental implant osseointegration based on torque-removal values in rabbits. Sixty-four identical titanium dental implants were placed using a standardized surgical protocol in the bilateral distal femur and proximal tibia of 16 New Zealand white rabbits (64 implants total). One week before implant placement, 8 rabbits were given doses of strontium ranelate (625mg/kg/day) until euthanized. The other 8 rabbits were untreated controls. One rabbit of each group were sacrificed in time of 15, 30, 45, 60, 75, 90, 105, 120 days, and torque-removal values were determined using a digital torque wrench for all implants. Analyses of torque data showed no statistical differences between the strontium ranelate and control groups. Based on the findings of this study, we can conclude that the time of 15 to 120 days of strontium ranelate administration does not interfere with the timing of early dental implant osseointegration in an animal model.

Malignant tumors of non-epithelial origin are considered rare in the head and neck region and they can show great morbidity and mortality. The aim of this study was to investigate the cases of sarcomas and melanomas in the head and neck region over the period from 1999 to 2008, in specialized centers located in the Municipality of Fortaleza. The data were collected from the register books of surgery of the head and neck and patient reports at the evaluated centers. Fifty-four cases were observed, being 36 sarcomas and 18 melanomas. As per the evaluation of the sarcomas, we have observed that the most assailed individuals were men with brown skin, ranging from 20 to 59 years old, with median age of 39.7. The relation man/woman was 1.7:1. The most prevailing histological type was the rhabdomyosarcoma, and the most attacked areas were the face and the cervical region. And as per the melanomas, adult men were also prevailing, ranging from 20 to 59 years old, with median age of 54.6. It has also been verified equal assailment in the brown and white races, with 33.3% in each one. The relation man/woman was 1.25:1. The most prevailing histological type was the superficial spreading melanoma, and the face skin was the most frequent location. In the evaluation of the origin, there was similarity in both diseases, being approximately half the patients in the capital city, and half in the state´s hinterland. As concerning the monitoring, the greatest part of the sample came from patients alive without evidence of the disease from the last consultation, corresponding to 41.6% in sarcomas and 44.5% in melanomas. The variation of therapy has also been observed in both groups, being the most common types of treatments, the association of surgery, radiotherapy and chemotherapy and surgery and radiotherapy for sarcomas and surgery, followed by surgery and radiotherapy for melanomas. Although malignant tumors of non-epithelial origin are rare in the head and neck region, they can show great morbidity and mortality and it is necessary the better understanding of their clinicalpatological aspects, in order to establish better treatment and life quality to these patients.

This paper describes a study assessing the knowledge of the lay public and health professionals about the oral and maxillofacial surgery in the city of Fortaleza, CE. Through questionnaires, were addressed to different groups including dentistry (group 1, n = 100) academic dentistry (group 2, n = 100), medical (group 3, n = 100), academic of medicine (group 4, n = 100), nurses (group 5, n = 100), academic of nursing (group 6, n = 100) and the lay public (group 7, n = 100) non-health professional with higher level or in course. It described several cases of clinical competence of oral and maxillofacial surgery and other not, and asked the respondents to choose a specialist to treat each case, including the plastic surgeon, the ENT, the oral and maxillofacial surgeon, the head and neck surgeon and the "other" option. The analysis consisted in the construction of contingency tables, applying the chi-square (X ²) and the extent of association of Cramer V. In comparison, bilateral tests were used where the value of the level of significance adopted in this study was α = 0.05. It was found that for fracture of nose, tongue cancer, increase in volume in the neck, cosmetic surgery of the nose and dissatisfaction with facial aesthetics, that all groups were classified as knowledge BAD. The analysis with the level of knowledge of groups, you can verify that when raised on aesthetic surgery of the nose there was no statistically significant difference with respect to knowledge of the groups. However, in assessing the level of knowledge regarding the dentoalveolar fractures, six were classified as OPTIMUM, the other (group 7, lay public) was rated as GOOD. When evaluated the removal of salivary gland, biopsy of lesions in the mouth, benign tumor of mandible, increase in volume in the mandible, children with cleft lip, palate and lip-palate, groups 3 and 4 (medical and academic medicine) were classified with knowledge BAD. To zygomatic fracture, treatment of cysts in the maxillary, mandibular graft, excessive jaw, jaw deficiency and excess of maxilla, there was also REGULAR. It was concluded that the sample of the results of the study assessing the knowledge of the data reveals CTBMF of poor knowledge in relation to groups, lack of education of society, poor perception of the population about the CTBMF with regard to area of operation, information, training and continuing education. For health professionals, especially the medical field, was found knowledge on diagnosis and surgical treatment, routing and guidance of treatment on the area of operation of the specialty (CTBMF).

A hanseníase é uma doença infecciosa crônica causada pela bactéria intracelular e acidorresistente Mycobacterium leprae, que acomete preferencialmente pele e nervos periféricos, com um grande potencial para desenvolver incapacidades físicas. Os objetivos deste trabalho foram verificar o conhecimento e atuação do cirurgião-dentista no controle e eliminação da hanseníase, na Secretaria Executiva Regional (SER) III, no Município de Fortaleza-CE, Brasil; bem como avaliar a autopercepção sobre a saúde bucal e necessidade de tratamento de portadores de hanseníase no referido Município. Tratou-se de um estudo transversal e descritivo, cuja amostra foi composta de 31 cirurgiões-dentistas (CD) da SER III e cem portadores de hanseníase atendidos no Hospital Universitário Walter Cantídio, em Fortaleza-CE. Os dados foram obtidos mediante um questionário estruturado para os cirurgiões-dentistas e outro para os portadores de hanseníase. A análise de dados foi realizada pelo programa Stata 11, tendo-se empregado o teste de Pearson e o teste de Fisher, para verificar associação entre as variáveis, considerando significativo quando o valor de p < 0,05. Os resultados mostraram que 64,52% dos profissionais nunca suspeitaram ter atendido casos de hanseníase, nenhum CD realizou avaliação programática de portadores de hanseníase, apesar da presença de focos infecciosos orais serem uma das causas das reações hansênicas. A autopercepção da necessidade de tratamento odontológico pelos portadores de hanseníase apresentou associação estatística com a escolaridade, sendo que, quanto maior a escolaridade, maior a percepção da necessidade de tratamento (p = 0,000). A análise bivariada mostrou existir associação estatística entre a classificação da saúde bucal e a autopercepção da necessidade de tratamento (p=0,054). Os pacientes que classificaram sua saúde bucal em péssima, ruim e regular percebiam ter maior necessidade de realizar tratamento odontológico quando comparados com os pacientes que classificaram sua saúde bucal como boa e ótima. Destaca-se a necessidade de aprofundamento dos conhecimentos dos cirurgiões-dentistas quanto à hanseníase e o desenvolvimento de atividades que atuem no controle e eliminação da hanseníase no Município estudado. A autopercepção do portador de hanseníase quanto a sua saúde oral e necessidade de tratamento deve, juntamente com uma avaliação clínica, servir como guia para a execução de políticas públicas que visem a favorecer um tratamento odontológico mais efetivo para esses pacientes.

The computational-mechanical analysis allows a more realistic modeling of pavements, which may result in a more reasonable design. However, in order to have increased accuracy in the analysis, a more adequate constitutive behavior of pavement materials must be taken into consideration, as well as dynamic effects, inertial forces from loading. This work presents a simplified methodology for viscoelastic analysis of asphalt mixtures considering the dynamic effect due to the load. The numerical analysis is done with a Finite Element Method (FEM) based software. The steps of the methodology are defined as: (i) laboratory test on hot mix asphalt in order to obtain the dynamic compliance of a HMA, (ii) interconversion from dynamic compliance to relaxation modulus (which is a more adequate input for FEM) and (iii) viscoelastic numerical analysis using FEM taking into consideration the dynamic effects of a load pulse. In order to illustrate the proposed methodology, a viscoelastic dynamic analysis example of a standard pavement is shown and compared to the traditional elastic-static analysis, which illustrates the difference between the two methods. We hope the present work can motivate the use of a more advanced analysis of asphalt pavements and that it can contribute to the viscoelastic characterization of Brazilian asphalt mixtures, resulting in more realistic pavement design parameters.
