This study aimed to report a treatment of multiple gingival recession in a 43-year-old female patient. After clinical and tomographic evaluation, Miller's class I and II (or Cairo RT1) gingival recessions were observed in several teeth of maxilla and mandible. Non-carious cervical lesions, poorly adapted crowns and unbalanced occlusion were also diagnosed, with the absence of canine guides. A thin gingival phenotype was also found. Orthodontic treatment was not performed, as a thin vestibular bone wall in the mandible was detected. Therefore, correction of the occlusion was performed by means of selective wear on cusps of the posterior teeth to relieve premature contacts. For root coverage, tunneling technique was used in the first, second and fourth sextants. In the fifth sextant, full covering occurred only after a second surgery. A third surgery was performed in the fourth quadrant, and the modified Bruno technique was chosen. The donor region was the palate in all the procedures. The two techniques employed reached up to 100% root coverage in all areas that received the surgery. The patient was satisfied with the final result. It was concluded that complete root coverage is possible when using tunneling technique in patients without interproximal bone loss. [ABSTRACT FROM AUTHOR]

Periodontal diseases are chronic diseases of oral cavity comprising of inflammatory conditions which effect the supporting structures of dentition. It is a multifactorial disease which is also known to be affected by genetic and environmental factors. However, some of the clinical parameters such as probing depth, attachment level, plaque index, bleeding on probing and radiographic assessment of alveolar bone are known to assess the severity of disease, although the disease activity is not measured. In the current scenario the salivary diagnostic markers for diagnosis of periodontal diseases have included the salivary enzymes, immunoglobulins, bacterial components or products, phenotypic markers such as epithelial markers. Also, saliva is a mirror of oral and systemic health and a valuable source to find out the physiological aspects of periodontal diseases. The present review thus highlights various salivary biomarkers which are quick, easy and reliable method for assessing and monitoring periodontal disease that improves and speeds treatment decisions and moves the field closer to individualized point-of-care diagnostics.

The quality of Cone Beam Computed Tomography (CBCT) images is directly influenced by scanning and visualization protocols. Evaluate the subjective quality of the Cone Beam Computed Tomography (CBCT) image of different devices and protocols for diagnosing periodontal structures and correlate the findings with the contrast-to-noise ratio (CNR). One dry dentate mandible was scanned by six CBCT devices: Accuitomo 3D 170, CS 9000, CS 9300, Eagle 3D, i-CAT Classic, and Orthophos XG 3D. All CBCT devices were adjusted to provide a spatial resolution closest to 0.2 mm, and a FOV height limited to less than 100 mm. Cross-sectional images were evaluated randomly. The buccal bone coverage, the periodontal ligament space and the amount of image noise were assessed. The statistics were calculated based on a logistic regression model with the significance level set at 5%. Protocols with large FOVs demonstrated significantly lower image quality. No statistical differences were found regarding buccal bone coverage between the CBCT devices. The CNR showed the highest value for the Accuitomo 60mm x 60mm HiFi 180°, followed by the Accuitomo 60mm x 60mm HiFi 360°, and lower values for the i-Cat Classic and Orthophos XG 3D devices. Most protocols studied presented good image quality in evaluating the buccal bone coverage and periodontal ligament space. However, the exam with the lowest FOV of the Accuitomo 60mm x 60mm HiFi 180° device showed superiority concerning the others. [ABSTRACT FROM AUTHOR]

There is an increasing demand for orthodontic treatment by adult patients in dental offices. Orthodontic treatment in adults has particular characteristics, because, in addition to not showing active growth, there are situations that demand interrelation with other areas of dentistry, such as, Periodontics, Dental Prosthesis, Restorative Dentistry and Implantology. The objective of this work was to describe a clinical case of an adult patient with periodontal involvement, establishing the main considerations to be taken in the orthodontic treatment of adult patients with periodontal involvement. The results obtained in the clinical case showed that it is possible to treat patients with periodontal involvement as long as some precautions are taken, such as strict hygiene control, in association with the specialty of periodontics, a reduced sequence of wires, in order to shorten treatment time, using low intensity forces, to minimize damage to periodontal tissues. The orthodontic treatment performed, gave the patient the desired smile functionality and aesthetics, prioritizing a strict hygiene control, the use of light forces, simplification in orthodontic movement, as well as the use of fixed and permanent restraints in areas of reduced periodontium.

Objetivo: avaliar a possível associação entre obesidade, doença periodontal e os mecanismos envolvidos no processo inflamatório. Materiais e Métodos: trata-se de uma revisão integrativa na qual realizaram-se buscas nas bases de dados Medline e SciELO (Scientific Electronic Library). Os Descritores em Ciências da Saúde (DeCS) obesidade, periodontite, terapia periodontal foram combinados por meio do conector booleano “and” nos idiomas português e inglês. Na busca foram encontrados 100 artigos, 72 na Medline e 28 na SciELO. A primeira seleção foi realizada através da leitura dos títulos e resumos dos artigos, excluindo os repetidos. Posteriormente, foi feita a leitura na íntegra. Destes, foram encontrados 7 na Medline e 4 na SciELO, além de outros estudos selecionados manualmente. Foram incluídos 18 artigos publicados no período de 2010 a 2020. Resultados: ao analisar a literatura os resultados foram contraditórios. Dos onze artigos selecionados, quatro mostraram associações significativas entre a obesidade e doença periodontal, principalmente, a periodontite crônica. Essa possível associação relaciona-se com o aumento de citocinas pró-inflamatórias, interleucina-6, fator de necrose tumoral e adipocitocinas como a visfatina, que são produzidas pelo tecido adiposo e estão presentes no fluido crevicular. Além disso, estudos mostraram um aumento na microbiota gengival de Tannerella forsítia, Porphyromonas gingivalis, Treponema Denticola, e Aggregatibacter actinomycetemcomitan em pessoas obesas. Esse fato, predispõe esses indivíduos a um maior risco para desenvolver doenças periodontais. Seis artigos não demonstraram relações significativas entre essas condições. Eles confirmaram a eficácia da terapia periodontal básica no controle da doença, mas não houve diferença na resposta inflamatória de pessoas obesas e não obesas. Conclusão: são necessários mais estudos, principalmente de caráter longitudinal, para confirmar essa associação. Ainda existem muitas lacunas na literatura, o que não permite afirmar com veracidade a associação entre sobrepeso e doença periodontal.

Introdução: Enfisema subcutâneo ocorre quando ar comprimido é introduzido em tecidos moles dos planos faciais através de uma barreira intrabucal descontinuada. Tem sido associado a alguns casos em consequência de tratamentos dentários, como extração de terceiros molares e tratamento endodôntico. O diagnóstico precoce e o manejo correto são fundamentais para a prevenção da progressão da lesão e futuras complicações, pois pode se espalhar pelos profundos planos faciais do pescoço, ocasionando enfisema retrofaríngeo e, ainda, pode causar pneumotórax e pneumomediastino. Objetivo: Avaliar a ocorrência de enfisema subcutâneo no estado do Rio Grande do Sul. Metodologia: Um questionário foi enviado por e-mail aos profissionais especialistas em Cirurgia e Traumatologia Bucomaxilofacial (CTBMF), Periodontia e Endodontia registrados no Conselho Regional de Odontologia (CRO-RS), contendo 8 perguntas: especialidade, conhecimento em relação ao enfisema subcutâneo e causa, número de cirurgias realizadas mensalmente, instrumento mais utilizado para procedimento cirúrgico, instrumento envolvido nos casos conhecidos, instrumento utilizado para secagem dos canais radiculares em endodontia, se já possuiu paciente com enfisema subcutâneo e se ouviu falar sobre enfisema durante a prática clínica. Resultados: Foram enviados 1954 questionários, obtendo 260 respostas dentro dos critérios da pesquisa (13,3%). A grande maioria da amostra (89,1%) relatou ter conhecimento sobre enfisema subcutâneo e suas complicações e 28 (10,7%) profissionais já tiveram casos relacionados a procedimentos odontológicos. Conclusões: O conhecimento por parte dos profissionais da área da odontologia sobre enfisema subcutâneo é importante, pois a partir desse estudo observamos que, apesar de raro, 10,7% dos entrevistados já tiveram casos de enfisema subcutâneo relacionados a procedimentos odontológicos.

Resumo Introdução A sonda periodontal é a melhor ferramenta para o diagnóstico clínico da doença periodontal, porém o desenho da sonda pode influenciar nos resultados. Objetivo Avaliar as características estruturais de sondas periodontais do tipo Williams disponíveis no mercado brasileiro e avaliar sua utilização clínica durante a sondagem periodontal. Material e método Os grupos de sondas foram divididos em: 1) Hu-Friedy® (n = 15); 2) Trinity® (n = 15); 3) Fava® (n = 15); 4) Millennium® (n = 15). Foram avaliados in vitro: peso (g), diâmetro da ponta ativa (mm), diâmetro do cabo (mm) e milimetragem das sondas (mm). Para o estudo in vivo, foram selecionados 10 participantes que apresentavam pelo menos quatro dentes com periodontite. As marcas de sondas foram codificadas em A, B, C e D para o cegamento do examinador. Resultado Verificou-se um diâmetro da ponta ativa sugestivo de forma tridimensional cônica para as marcas Trinity®, Hu-Friedy® e Millennium®, com conicidade crescente, enquanto a marca Fava® revelou forma tridimensional cilíndrico/paralelo. A sonda Fava® apresentou os maiores diâmetros nos terços inicial e médio, enquanto a Hu-Friedy® revelou menor diâmetro no terço inicial. Todas as sondas apresentaram milimetragem similar. No estudo clínico, verificou-se que a sonda Fava® resultou em menor média de profundidade de sondagem do que às demais. Conclusão As sondas periodontais apresentam diferenças estruturais que devem ser consideradas durante a seleção do instrumento, sendo que as sondas cônicas apresentam resultados mais confiáveis à prática clínica, pois o desenho da sonda interfere diretamente no diagnóstico clínico da doença periodontal.

Gingival smile is a term used to describe an aesthetic condition in which excessive gingival exposure at the jaw level occurs during smile. There are several factors related to its etiology, the most common is the altered passive eruption of anterior superior teeth. To correct this disharmony, a multidisciplinary approach is necessary, and the treatment plan depends on a correct diagnosis and assessment for a better prognosis. The present study aims to describe a clinical case where periodontal surgical techniques were used to correct this condition. Female patient, 25 years old, with aesthetic complaint of the amount of gum exposed when smiling and diagnosed with altered passive eruption. Clinical crown augmentation surgery was performed on the anterior superior teeth. After 1 and 2 years, periodontal clinical parameters (probing bleeding, probing depth, clinical attachment level, crown length, keratinized mucosa width and plaque index) were reassessed, through clinical examination, digital photographic monitoring and measurement tools. In two years, it was possible to note the stability of the results achieved, maintaining values similar to those of the immediate postoperative period. The case report confirmed the success of the clinical crown augmentation surgery and the periodontal parameters stability evaluated after 2 years. [ABSTRACT FROM AUTHOR]

A saúde da mulher é um dos temas abordados pela medicina periodontal, a qual estuda a influência da doença periodontal na saúde sistêmica, e os efeitos que as comorbidades do paciente causam na progressão da doença periodontal. Durante a gestação, a condição periodontal vem sendo associada ao nascimento de bebês prematuros e/ou baixo peso, devido à presença de bactérias gram-negativa se seus produtos conseguirem atingir o líquido amniótico por via hematogênica, e a mesma ser exacerbada pelas alterações hormonais características desta fase. O objetivo deste presente estudo foi através de uma revisão de literatura, compreender a relação entre a doença periodontal e as complicações geradas durante o período gestacional, e assim, reafirmar a necessidade e importância da prevenção e acompanhamento odontológico no pré-natal.

Tendo em vista a intensa relação entre periodontia e prótese, a pesquisa aqui proposta tem como principal objetivo avaliar a condição periodontal dos pacientes usuários de prótese parcial fixada clínica odontológica da Universidade Federal de Campina Grande. A população do estudo foi composta por pacientes reabilitados com prótese parcial fixa unitária, a partir de 2012, na clínica odontológica da UFCG. Os dados coletados no exame clínico foram: índice de placa, índice gengival, profundidade de sondagem e exame radiográfico. As informações foram registradas no Excel e analisadas por estatística descritiva. Dos pacientes examinados, em quatro foi observado o insucesso da prótese; e treze pacientes foram submetidos ao exame clínico. Obteve-se um total de quinze próteses fixas unitárias, todas do tipo metalocerâmica; no índice periodontal simplificado61,5% dos pacientes apresentaram condição periodontal 2,que indica presença de cálculo sem existência de bolsa; na sondagem periodontal do elemento pilar os maiores valores encontrados foram para as faces proximais; nos achados radiográficos apenas um paciente apresentou reabsorção óssea. Concluiu-se que apesar de todos os pacientes apresentarem inflamação gengival, as próteses apresentavam-se satisfatórias.

A odontologia, através da periodontia, busca vencer o desafio de restituir a função, a fonética, o conforto e a saúde do sistema estomatognático do paciente. Com a introdução, e o sucesso, dos procedimentos de correção do sorriso gengival a ideia do sorriso perfeito passou a ser mais comentado nas clínicas odontológicas, agradando tanto pacientes como cirurgiões-dentistas. Com a evolução da tecnologia e dos materiais odontológicos, hoje, é possível fazer o ensaio do resultado final da cirurgia plástica periodontal, sendo assim, de muito mais fácil aceitação por parte dos pacientes. O sucesso desse tratamento que hoje é bem documentado graças à ação multidisciplinar entre periodontistas, ortodontistas, protesistas e cirurgiões bucomaxilofaciais, buscando um correto diagnóstico para a escolha adequada da modalidade de tratamento. O objetivo deste trabalho é avaliar as formas de correção do sorriso gengival dentro de sua necessidade multidisciplinar.

Resumo Introdução A determinação do fenótipo gengival possibilita compreender melhor as variações e diferenças clínicas intra e interindividuais dos tecidos periodontais saudáveis. Objetivo O objetivo deste estudo foi determinar os perfis do fenótipo gengival e compará-los em diferentes regiões da cavidade oral, levando em consideração parâmetros clínicos relacionados aos tecidos moles circunjacentes nos dentes anteriores superiores e inferiores. Material e método Noventa e um pacientes com saúde periodontal foram examinados e os parâmetros clínicos profundidade de sondagem (PS), largura de mucosa ceratinizada (MC), espessura gengival em ambos incisivos centrais superiores (EG) e fenótipo gengival (FG) foram coletados nos dentes anteriores superiores e inferiores. Os dados foram analisados estatisticamente pelos testes t-Student pareado e independente, Correlação de Pearson e Qui-quadrado, com um nível de significância de 5%. Resultado O fenótipo gengival espesso predominou nos dentes anteriores superiores (60,5%), enquanto o fenótipo fino foi mais prevalente nos dentes anteriores inferiores (84,6%). Diferenças estatisticamente significativas foram encontradas para os parâmetros largura de mucosa ceratinizada e espessura gengival em relação aos fenótipos gengivais superiores e inferiores (p

A instalação de implantes imediatos em alvéolos frescos reduz a reabsorção fisiológica do rebordo alveolar. Porém, podem ser observados defeitos peri-implantares, devido à diferença entre o diâmetro do dente e implante. Esses defeitos podem comprometer a manutenção do osso peri-implantar e, consequemente, a estética do tratamento reabilitador. Para a manutenção do volume ósseo, diversos biomateriais podem ser utilizados, dentre eles destaca-se o Beta-Tricálcio Fosfato (β-TCP). O β-TCP é uma biocerâmica reabsorvível que atua como um arcabouço para a formação óssea, sendo gradualmente substituído por tecido ósseo. Assim o objetivo desse artigo foi demonstrar a utilização do β-TCP para preenchimento de defeitos peri-implantares e de alvéolos frescos. Inicialmente, foi realizada a exodontia minimamente invasiva dos elementos dentários 13 a 23, em seguida, foram instalados 4 implantes nos alvéolos dos dentes 11, 13, 21 e 23. Ao final da instalação dos implantes, os defeitos peri-implantares e os alvéolos frescos residuais foram preenchidos com β-TCP. Após 8 meses, foi realizada a confecção da prótese definitiva. O presente caso teve um acompanhamento clínico e radiográfico de 18 meses, com a preservação do volume ósseo alveolar. Considerando que o preenchimento favoreceu o sucesso da reabilitação implantossuportada, garantindo a manutenção do volume ósseo, pode-se considerar o β-TCP uma opção adequada para o preenchimento de defeitos ósseos periimplantares.

Among the available techniques for gingival recession treatment, the main surgical technique for gain of keratinized tissue is the free gingival graft. This procedure is also indicated for vestibule extension and frenulum removal. The technique consists of the epithelial and connective tissues removal from a donor site and its repositioning on to a recipient site, being an effective primary stability mandatory for the healing process. The aim of this study was to describe a case report of a 35-year-old male, who reported a postoperative complication in donor area, after a free gingival graft which occurred 07 days later. This situation occurred after patient reported having rinsed his mouth with hot water during shower. Due to that, a 1mm thick acetate tray was readymade for the donor site comfort and protection. Among the demands presented in this case, free gingival graft was the primary surgical choice to increase keratinized tissue. Despite the patient's morbidity, due to the two surgical sites, the use of the acetate tray showed great reduction in patient's discomfort and trauma. This approach proved to be successful since the patient described increase in self-esteem and oral hygiene facilitation which in combination contributed to satisfactory final results.

OBJECTIVE: The present study assessed the maxillary dental arch changes produced by surgically assisted rapid maxillary expansion (SARME). METHODS: Dental casts from 18 patients (mean age of 23.3 years) were obtained at treatment onset (T1), three months after SARME (T2) and 6 months after expansion (T3). The casts were scanned in a 3D scanner (D-250, 3Shape, Copenhagen, Denmark). Maxillary dental arch width, dental crown tipping and height were measured and assessed by ANOVA and Tukey's test. RESULTS: Increased transversal widths from T1 and T2 and the maintenance of these values from T2 and T3 were observed. Buccal teeth tipping also showed statistically significant differences, with an increase in all teeth from T1 to T2 and a decrease from T2 to T3. No statistically significant difference was found for dental crown height, except for left first and second molars, although clinically irrelevant. CONCLUSION: SARME proved to be an effective and stable procedure, with minimum periodontal hazards.

RESUMO Agentes químicos têm sido usados para auxiliar na inibição da formação do biofilme e impedir desenvolvimento da doença periodontal (DP). O objetivo deste estudo foi avaliar radiograficamente a ação do extrato de própolis na progressão da DP induzida em ratos. Foram utilizados 48 ratos Wistar, divididos em 4 grupos (n=12): Controle, Pincel, Própolis e Clorexidina. Os grupos foram subdivididos para análise aos 7 e 21 dias. A progressão da DP foi avaliada radiograficamente pela distância entre a junção cemento-esmalte e a crista óssea alveolar na face mesial do 1º molar inferior. A perda óssea foi significativamente menor nos animais do grupo própolis em ambos os períodos (p ≤ 0,01). Concluiu-se por análise radiográfica que a aplicação tópica do extrato de própolis interfere reduzindo a progressão da doença periodontal induzida por ligadura em ratos, demonstrando a importância desse composto como substância auxiliar no tratamento periodontal.

Objective: To investigate whether there is scientific evidence to support the hypothesis that the presence of orthodontic fixed appliances influences the oral microbiota. Methods: The search for articles was conducted in PubMed; ISI Web of Knowledge and Ovid databases, including articles published in English until May 17th, 2012. They should report human observational studies presenting the following keywords: "fixed orthodontic appliance" AND "microbiological colonization"; OR "periodontal pathogens"; OR "Streptococcus"; OR "Lactobacillus"; OR "Candida"; OR "Tannerella forsythia"; OR "Treponema denticola"; OR "Fusobacterium nucleatum"; OR "Actimomyces actinomycetemcomitans"; OR "Prevotella intermedia", OR "Prevotella nigrescens"; OR "Porphyromonas gingivalis". Articles were previously selected by title and abstract. Articles that met the inclusion criteria were analyzed and classified as having low, moderate or high methodology quality. A new detailed checklist for quality assessment was developed based on the information required for applicable data extraction for reviews. The study design, sample, follow-up period, collection and microbial analysis methods, statistical treatment, results and discussion were assessed. Results: The initial search retrieved 305 articles of which 33 articles were selected by title and abstract. After full-text reading, 8 articles met the inclusion criteria, out of which 4 articles were classified as having low and 4 as moderate methodological quality. The moderate methodological quality studies were included in the systematic review. Conclusions: The literature revealed moderate evidence that the presence of fixed appliances influences the quantity and quality of oral microbiota.

A presente pesquisa objetivou avaliar clinicamente o efeito de bochechos à base de extratos das plantas medicinais, aroeira (Schinus terebinthifolius) e camomila (Matricaria recutita L.), sobre o controle da placa bacteriana e o tratamento da gengivite. Para tanto, foi realizado um ensaio clínico randomizado, duplo cego, intervencionista, envolvendo 59 indivíduos adultos atendidos na Clínica do Curso de Odontologia da Universidade Estadual da Paraíba (UEPB). A amostra foi constituída por pacientes portadores de gengivite crônica. A referida amostra foi selecionada aleatoriamente e dividida em três grupos: bochecho com Clorexidina (grupo controle positivo); bochecho com Camomila (grupo teste 1); bochecho com Aroeira (grupo teste 2). Durante a primeira visita do paciente, e, previamente à realização dos bochechos, todos foram orientados quanto à higiene bucal e submetidos ao procedimento de raspagem e alisamento radicular (RAR) da boca toda em uma única sessão. Os bochechos foram realizados a partir do primeiro atendimento clínico até o 15º dia após o início do tratamento, na frequência de duas vezes ao dia. Para avaliação da condição periodontal da amostra realizada no 1º, 7º e 15º dias foram aplicados os Índices de Sangramento Gengival (ISG) e de Placa (IP). Os pacientes foram reavaliados 7 e 15 dias após o início do uso do respectivo bochecho. Os resultados apontaram que o IP e o ISG apresentaram redução significativa nos três grupos. Quanto ao IP, o bochecho de camomila obteve a maior redução de acúmulo de placa e o bochecho de aroeira, a menor redução. Para os índices de sangramento, os resultados foram equivalentes, de forma que não foram consideradas diferenças estatisticamente significativas entre os bochechos. Foram considerados satisfatórios os bochechos a base de Camomila (Matricaria recutita L.) e Aroeira (Schinus terebinthifolius) na redução do quadro de inflamação gengival da amostra, sendo o bochecho de Camomila (Matricaria recutita L.) o que apresentou melhor desempenho na redução do índice de placa bacteriana.This study aimed to clinically evaluate the effect of mouthwash with extracts from the medicinal plants aroeira (Schinus terebinthifolius) and chamomile (Matricaria recutita L.) on plaque control and gingivitis treatment. Thus, a randomized, double-blind interventional clinical trial was conducted, involving 59 adults treated at the Clinics of the Dentistry Program of Univ Estadual da Paraíba (UEPB). The sample consisted of patients with chronic gingivitis. This sample was randomly selected and divided into three groups: mouthwash with chlorhexidine (positive control group), mouthwash with chamomile (test group 1); mouthwash with aroeira (test group 2). During the first visit, and prior to rinses, all patients were instructed in oral hygiene and subjected to scaling and root planing procedure (SRP) of the whole mouth in one single session. Rinses occurred from the first clinical appointment to the 15th day after the beginning of treatment, twice a day. To evaluate the periodontal condition of the sample on the 1st, 7th and 15th days, Gingival Bleeding Index (GBI) and Plaque Index (PI) were used. The patients were reassessed at 7 and 15 days after the beginning of the respective rinses. Results indicated that PI and GBI significantly decreased in all three groups. As to PI, chamomile mouthwash led to the greatest reduction in plaque buildup, while aroeira mouthwash resulted in the smallest reduction. For bleeding rates, results were equivalent so that statistical differences among rinses were not considered significant. Mouthwashes with chamomile (Matricaria recutita L.) and aroeira (Schinus terebinthifolius) were considered satisfactory in reducing gingival inflammation in the sample; in addition, mouthwash with chamomile (Matricaria recutita L.) showed the best performance in reducing the plaque index.

INTRODUCTION: Currently, people's esthetic requirements and expectations have increased substantially. Therefore, dentists have been seeking ways to provide excellent treatment results which, consequently, increasingly require a well organized transdisciplinary approach. The link between orthodontics and periodontics became evident from the moment professionals began to understand the biology of tooth movement. As regards smile esthetics, however, such cooperation is now essential. OBJECTIVE: To show clinically how and when orthodontists and periodontists should work jointly to enhance smile esthetics based on the display and harmony of the gingival contour.INTRODUÇÃO: nos dias atuais, as expectativas e exigências estéticas das pessoas têm aumentado substancialmente. Por isso, a Odontologia vem buscando maneiras de oferecer tratamentos com resultados excelentes e, consequentemente, necessita trabalhar, cada vez mais, de modo transdisciplinar. A inter-relação da Ortodontia com a Periodontia é evidente desde quando se compreendeu a biologia da movimentação dentária; contudo, em se tratando de estética do sorriso, tornou-se fundamental. OBJETIVO: evidenciar, clinicamente, como e quando a Ortodontia e a Periodontia devem trabalhar de modo integrado para a obtenção de sorrisos mais estéticos, considerando-se a exposição e a harmonia do contorno gengival.

Periodontal disease (PD) is widely known among veterinarians for its high prevalence and serious consequences to the dogs. The objective of this study was to assess the occurrence of PD in dogs that live in the micro-region of Viçosa, treated at the Veterinary Hospital of the Federal University of Viçosa (HVT - Hospital Veterinário da Universidade Federal de Viçosa), as well as to assess how aware of this disease dog owners are. In order to do so, all dogs treated at the HVT from March 10th, 2009 to November 30th, 2009, on alternate days, had their oral cavities examined. Medical history data, such as age, type of food, main complaint and owner consent, halitosis, presence of dental calculus, inflammation and gingival recession and tooth loss, were collected. A prevalence of 88.67% was found for PD in dogs referred to the HVT, and 2.67% were referred due to this disease. Of all the owners who participated in the study, 43.83% knew about periodontal disease and of these 17.46% made use of some type of prevention or treatment. Therefore, periodontal disease is highly prevalent and the owners are not aware of the disease. Thus, a dog owner clarification program on periodontal disease is needed in the area where HVT-UFV operates.

A associação entre doença periodontal e o desenvolvimento de aterosclerose tem sido pesquisada. Esta revisão sistemática da literatura se propõe a verificar a associação entre a doença periodontal e a aterosclerose subclínica. A pesquisa utilizou as bases de dados: PubMed, Scopus, LILACS, BBO, Biblioteca Cochrane e Scielo com os termos: "doença periodontal", "periodontite", "carótida" e "aterosclerose". Foram excluídos artigos: que apresentaram resumos escritos em idiomas diferentes do português, inglês e espanhol; com abordagem laboratorial em modelos experimentais; sem descrição ou referência a estimadores de associação entre doença periodontal e aterosclerose subclínica; pesquisas que realizaram a medida da doença periodontal por parâmetros diferentes de exames clínicos; pesquisas que não analisaram a espessura da íntima média da artéria carótida através de exame de ultrassom; e que abordassem grupos específicos. Foram comparados os desenhos de estudo, protocolos de medida e os dados relatados. De um total de 63 referências, apenas 10 artigos contemplavam todos os critérios de inclusão, distribuídos em: 1 estudo longitudinal, 6 transversais e 3 casos controles. Observou-se uma heterogeneidade entre os estudos em relação ao método de mensuração da doença periodontal e os desfechos da aterosclerose. Concluiu-se que infecções periodontais são fortemente associadas ao desenvolvimento da aterosclerose subclínica, entretanto os mecanismos envolvidos no processo patogênico ainda permanecem desconhecidos.The association between periodontal disease and the development of atherosclerosis has been studied. The systematic review of literature aims to evaluate the association between periodontal disease and subclinical atherosclerosis. A literature search of the PubMed, Scopus, LILACS, BBO, Cochrane Library and Scielo bibliographic databases was conducted using the following descriptors: "periodontal disease", "periodontitis", "carotid", and "therosclerosis". Articles were excluded if they: presented abstracts written in languages other than Portuguese, English and Spanish; experimental studies; did not contain data testing the degree of association between periodontal disease and subclinical atherosclerosis; did measure the extent of periodontal disease by parameters other than the clinical examination; did not measure the carotid artery intima-media wall thickness by ultrasonography; and covered specific population groups. The studies design, measurement protocols and reported data were compared. A total of 63 papers identified only 10 studies that met the inclusion criteria: 1 longitudinal study, 6 cross-sectional, and 3 case control studies. There was a wide heterogeneity between the studies regarding the methods of measuring periodontal disease and atherosclerosis outcomes. The conclusion is that periodontal infections are strongly associated with the development of subclinical atherosclerosis, however the mechanisms involved on the pathogenic process remain unknown.

OBJETIVO: Este estudo descreveu a prevalência de condições periodontais e sua associação com variáveis demográficas, socioeconômicas e comportamentais em adultos de 35 a 44 anos residentes no município de Guarulhos, São Paulo, 2006. MÉTODOS: Foi realizado estudo transversal de base populacional com delineamento amostral por conglomerados. Os inquéritos e os exames foram realizados nos domicílios sorteados. Para avaliação da condição periodontal foi utilizado o índice Community Periodontal Index (CPI). Os dados foram apurados pelo programas EPIINFO 6 e STATA 10. Para o modelo de associação empregou-se a razão de prevalências (RP), calculada por meio de análise de regressão de Poisson, com correção para delineamento de amostras complexas e ponderação pelo peso populacional. RESULTADOS: Foram examinadas 263 pessoas em 237 domicílios. No estudo multivariado, com modelo ajustado para amostras complexas e ponderação populacional, a prevalência de sangramento gengival e cálculo dentário esteve associada significativamente ao fato de ser homem (RP=1,12, p=0,04), fumante (RP=1,11, p=0,01), ter menos de oito anos de estudo (RP=1,14, p=0,01) e não visitar o cirurgião-dentista (CD) há mais de dois anos (RP=1,19, p=0,00). Para a presença de bolsa periodontal, houve associação com adultos que relataram o hábito de fumar (RP=1,71, p=0,02) e apresentavam mais de dois anos sem frequentar o CD (RP=1,97, p=0,03). CONCLUSÃO: Houve maior prevalência (62,7%) de indivíduos com sangramento gengival e cálculo dentário em relação à presença de bolsas periodontais rasas ou profundas (26,6%); as primeiras, reversíveis, têm possibilidades de resolução por meio de procedimentos de atenção básica em saúde bucal.OBJECTIVE: This study described the prevalence of periodontal conditions and assessed its association with social, economical and behavioral variables in adults aged 35 to 44 years old, residents in the city of Guarulhos, State of Sao Paulo, 2006. METHODS: This study was a population based survey with cluster sampling. Data collecting and exams were done at houses drew at random. The Community Periodontal Index was used to assess the periodontal condition. Data analysis used EPIINFO 6 and STATA 10 softwares. The assessment of association used the prevalence ratio (PR), as calculated by Poisson regression models with complex sampling and weighted sample adjustments. RESULTS: The total number of people was 263 in 237 domiciles. In the multivariate model, the prevalence of gingival bleeding and dental calculus was significantly associated to being male (PR=1.12, p=0.04), smoking (PR=1.11, p=0.01), school level of less than eight years of study (PR=1.14, p=0.01), and who have not received dental care for more than two years (PR=1.19, p

Gingival recession may cause cosmetic changes and root hypersensitivity, which can alter mastication and tooth brushing, and thus contribute to the progression of periodontal disease. Treatment of gingival recessions with subepithelial conjunctive tissue grafting is very predictable due to its bilaminar nature. However, some factors may influence the success of the procedure, among them: selection of the lesion; characteristics of the defect with regard to the depth and width of the recession, the deeper and wider the recession, the worse the prognosis, and also the presence of restorations. Furthermore, it is necessary to control the etiologic factors of recessions, such as inflammation and traumatic brushing, control of systemic factors, occlusal trauma, smoking and harmful habits, technical considerations and asepsis. The success of the procedure must be based on observing the possible factors that might influence their predictability, as well as respecting the basic principles of mucogingival surgery.

Objective: To verify the association between periodontal disease and lung disease from an epidemiological, case and control survey, in patients who attended the first aid service of the Adriano Jorge Foundation Hospital, Manaus, Amazonas, Brazil, from June 2006 to February 2007. Methods: The sample consisted of 140 patients, among whom community-acquired pneumonia was present in 60% (n = 70), and chronic obstructive pulmonary disease in 40% (case-group); and 70 patients without respiratory disease (control group), ranging between 19 and 69 years of ages, with a mean age of 41.3, and standard deviation of 13.6 years. The clinical parameters for evaluating periodontal changes were obtained by means of pocket depth, bleeding on probing, plaque index and clinical attachment loss. Results: Both groups showed no significant difference in any of the control variables (p>0.05). The groups showed significant difference only in the plaque index (p 0.05). Due to the increase in the bacterial plaque index in the oral cavity of patients with respiratory diseases, further studies should be conducted to verify what the relationship between the two diseases is.

Fundamental concepts of etiology, inheritance and clinical characteristics of Down syndrome are used in this review as a basis for submission of studies that focus on periodontal disease in individuals with Down syndrome, since almost 100% of them develop the disease in adult life. It is believed that in association with environmental and cultural factors related to hygiene and disabilities of coordination, the immunological characteristics that are found altered in individuals with Down syndrome, such as deficient neutrophil chemotaxis and reduced number of mature T lymphocytes, may contribute to the greater prevalence and severity of periodontal involvement in patients with Down syndrome. Moreover, the pattern of periodontal destruction observed in individuals with Down syndrome is consistent with aggressive periodontitis, with a predominance of periodontopathogens such as Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Tannerella forsythensis during childhood and adolescence of Down’s syndrome patients. It is possible to note a relationship between the development of molecular techniques and the evolution of knowledge about Down syndrome, for example: identification of the trisomy syndrome by observing only part of chromosome 21 (distal long arm); identification of genes in this trisomic region and the pattern of superexpression (or not) of these genes. Moreover, in this review future perspectives are presented with regard to better understanding Down syndrome in the genetic context, which will reflect in more individualized and effective clinical treatments that will provide these patients with a better quality of life.

Avanços na área de biologia molecular e celular têm contribuído para o desenvolvimento de técnicas de reparo ou, até mesmo, de regeneração de órgãos e tecidos injuriados por doenças, traumas e deformidades congênitas. A engenharia tecidual é um campo interdisciplinar que aplica princípios da engenharia, biologia e ciências clínicas para o desenvolvimento de substitutos biológicos que possam manter, restaurar, ou melhorar a função de órgãos e tecidos. Essa nova ciência está embasada em três pontos: células, matrizes biocompatíveis e moléculas bioativas responsáveis pelos sinais morfogênicos. As células usualmente empregadas são as células-tronco. Buscamos neste artigo atualizar os cirurgiões dentistas no conceito de engenharia tecidual e em que contesto está sendo pesquisada na Odontologia, mais especificamente nas áreas que envolvem periodonto e polpa.

The adult tends to be an excellent orthodontic patient, because he/she is motivated and cooperative. Nevertheless, many adult patientspresent periodontal problems. Intrusive movement is usually necessary against an area with infrabony defects, and in order for treatmentto be successful, it is necessary for all related aspects to be well understood. The aim of this study was to discuss the feasibility and efficacy of orthodontic intrusion as a means of reducing infrabony defects caused by periodontal disease. The methodology used was reviewed in the literature, from which articles were selected using the MEDLINE, LILACS and BBO databases. After periodontal treatment and maintenance with suitable bacterial plaque control has been performed, orthodontic treatment with intrusive tooth movement can be performed in case of pathological tooth migration and extrusion. The segmented arch technique is the most indicated for intruding teeth with infrabony defects because it is capable of developing light and continuous forces. Furthermore, although studies did not confirm, they suggested that orthodontic intrusion could lead to the formation of new periodontal support tissue. With a multidisciplinary approach, it is possible to successfully perform intrusion movements in teeth that present infrabony defects, provided that periodontal inflammation has been treated and the patient presents an excellent level of plaque control. Among the benefits of this approach are: better appearance, better access to dental hygiene, restitution of incisal occlusion and reduction in non axial load.

Objective: To make a clinical evaluation of periodontal alterations caused by cigarettes in smoker and non-smoker patients from two aspects: gingival plaque index and oral hygiene. Methods: Eighty patients of both sexes, ranging between 20 and 50 years of age, were selected and divided into four experimental groups (non-smoker patients without esthetic restorations, non-smoker patients with esthetic restorations, smoker patients without esthetic restorations, smoker patients with esthetic restorations). Results: The patients without restorations, irrespective of whether they were smokers or not, presented a lower gingival plaque index than the patients with restorations; that is, the presence of restorations exerts a strong influence on the increase in bacterial and gingival plaque indexes. With regard to oral hygiene, of the 40 smoker patients examined, many had been smoking for many years; in the majority of cases, around 20 cigarettes/day. Of the 80 patients examined (smokers and non-smokers), around 50% informed that they brushed their teeth three times a day, and 55 patients (over 50%) informed that they visited the dentist periodically. Of the 80 patients examined (smokers and non-smokers), only 17 returned to the dental consulting room every six months, while 26 patients informed that they went once a year. Balance was also found between smokers and non-smokers with regard to the presence of bad breath. (halitosis) Conclusion: Restorations had a strong influence on the increase in the bacterial and gingival plaque indexes, and over 50% of the patients examined informed that they visited the dentist periodically. As regards the presence of bad breath, it was found that around 40% of patients affirmed being aware of it.

There has been a constant search for a definition of criteria of susceptibility to periodontal diseases in modern Periodontology, as it is of the greatest importance, since it enables improvements in prevention, early diagnosis, treatment and prognosis of this disease. It is in this context that this literature review was conducted, with the object of verifying whether there is a greater propensity to periodontal disease in individuals with systemic lúpus erythematosus, a chronic inflammatory disease, whose pathogenesis presents some characteristics similar to those of the pathogenesis of periodontal disease. The majority of existent studies about the subject have pointed towards the possible existence of such susceptibility. Nevertheless, the relationship between this autoimmune disease and periodontal disease has not yet been well established, and the mechanisms by which the systemic disease influences the periodontal health of patients affected with it are not yet clear. Further studies are required in order to affirm that individuals with systemic lúpus erythematosus are a group of risk for the development of periodontal disease, and in order to understand the mechanisms involved in this possible relationship of susceptibility.

The aim of this study was to evaluate retrospectively the periodontal conditions of teeth with fixed crowns that had been in place from 3 to 5 years before the study was conducted. Forty individuals were recalled for a follow-up visit. Full-mouth clinical examinations were carried out and Visible Plaque Index (VPI), Gingival Bleeding Index (GBI), Probing Pocket Depth (PPD), and clinical attachment level (CAL) were assessed in 6 sites per tooth. Parallel radiographs were also taken and blindly analyzed by a digital caliper (distance between the apex and the bone crest). BANA tests were performed. A contra-lateral sound tooth was considered the control. Mean values were obtained and Wilcoxon and paired sample t tests were used to compare the test and control sites. Crowns had a mean VPI value of 30.42% as compared to 49.17% for sound teeth. The GBI was 33.33% and 26.25% for test and control teeth respectively. Assessment of PPD revealed values of 2.30 and 2.14 mm, and assessment of CAL revealed averages of 2.02 and 1.89 mm for test and control teeth respectively. The mean values for radiographic distances were 12.73 and 13.67 mm, and for the BANA test, 67.50 and 50.00 for sound and crowned teeth, respectively. Statistically significant differences were observed for all parameters except for CAL and for the BANA test. It may be concluded that, with the methods used in the present study, crowns may be associated with more signs of inflammation, however not with periodontal breakdown.O objetivo deste estudo foi avaliar retrospectivamente as condições periodontais de pacientes com coroas fixas colocadas de 3 a 5 anos antes da realização da pesquisa. Quarenta indivíduos foram rechamados. Exames clínicos de toda a boca foram realizados avaliando-se Índice de Placa Visível (IPV), Índice de Sangramento Gengival (ISG), Profundidade de Sondagem (PS) e Nível Clínico de Inserção (NCI) em 6 sítios por dente. Radiografias paralelas foram obtidas e analisadas cegamente por paquímetro digital (distância do ápice à crista óssea). Testes BANA foram realizados. Um dente hígido contralateral foi considerado como controle. Valores médios foram obtidos e testes de Wilcoxon e t pareado foram utilizados para comparar os sítios teste e controle. Coroas apresentaram um valor médio de IPV de 30,42%, comparado com 49,17% para dentes hígidos. O ISG foi de 33,33% e 26,25% para dentes com coroas e hígidos, respectivamente. A PS revelou valores de 2,30 e 2,14 mm e a análise do NCI demonstrou médias de 2,02 e 1,89 mm para dentes teste e controle, respectivamente. Os valores médios para as distâncias radiográficas foram de 12,73 e 13,67 mm, e para o teste BANA, de 67,50 e 50,00 para dentes hígidos e com coroas, respectivamente. Diferenças estatisticamente significantes foram observadas para todos os parâmetros, exceto para NCI e para o teste BANA. Pode-se concluir que, com os métodos utilizados no presente estudo, coroas podem ser associadas a mais sinais de inflamação, entretanto não com destruição periodontal.

The objective of this split-mouth, double-blind, randomized controlled trial was to compare the clinical effect of treatment of 2- or 3-wall intrabony defects with open flap debridement (OFD) combined or not with enamel matrix proteins (EMP). Thirteen volunteers were selected with one pair of or more intrabony defects and probing pocket depth (PPD) > 5 mm. All individuals received instructions regarding oral hygiene and were submitted to scaling and root planing. Each participant received the two treatment modalities: test sites were treated with OFD and EMP, and control sites received only OFD. After 6 months, a significant reduction was observed in PPD for the EMP group (from 6.42 ± 1.08 mm to 2.67 ± 1.15 mm) and for the OFD group (from 6.08 ± 1.00 mm to 2.00 ± 0.95 mm) (p < 0.0001), but with no significant difference between groups (p = 0.13). A significant gain in relative attachment level (RAL) was observed in both groups (EMP: from 13.42 ± 1.88 mm to 10.75 ± 2.26 mm, p < 0.001; OFD: from 12.42 ± 1.98 mm to 10.58 ± 2.23 mm, p = 0.013), but with no significant difference between groups (p = 0.85). Gingival recession (GR) was higher in the EMP group (from 1.08 ± 1.50 mm to 2.33 ± 1.43 mm; p = 0.0009) than in the OFD group (from 0.66 ± 1.15 mm to 1.16 ± 1.33 mm; p = 0.16), but this difference was not significant (p = 0.06). In conclusion, the results showed that OFD combined with EMP was not able to improve treatment of intrabony defects compared to OFD alone.O objetivo deste estudo clínico controlado, randomizado, duplo-cego, tipo boca-dividida foi comparar o efeito clínico do tratamento de defeitos infra-ósseos de 2 ou 3 paredes com retalho de espessura total (RET) associado ou não com a proteína da matriz do esmalte (PME). Treze voluntários com 1 par ou mais de defeitos infra-ósseos foram selecionados com profundidade clínica de sondagem (PCS) > 5 mm. Todos receberam instruções de higiene bucal, raspagem e alisamento radicular. Cada participante recebeu os dois tipos de tratamento: o lado teste foi tratado com RET e PME, e o lado controle recebeu somente RET. Após 6 meses, foi observada uma redução significante na PCS para o grupo PME (de 6,42 ± 1,08 mm para 2,67 ± 1,15 mm) e para o grupo RET (de 6,08 ± 1,00 mm para 2,00 ± 0,95 mm) (p < 0,0001), mas não houve diferença significante entre os grupos (p = 0,13). Um ganho significante de nível clínico de inserção relativo (NCIR) foi observado em ambos os grupos (PME: de 13,42 ± 1,88 mm para 10,75 ± 2,26 mm, p < 0,001; RET: de 12,42 ± 1,98 mm para 10,58 ± 2,23 mm, p = 0,013), mas não houve diferença significante entre os grupos (p = 0,85). A retração gengival (RG) foi maior para o grupo PME (de 1,08 ± 1,50 mm para 2,33 ± 1,43 mm; p = 0,0009) do que para o grupo RET (de 0,66 ± 1,15 mm para 1,16 ± 1,33 mm; p = 0,16), mas essa diferença não foi significante (p = 0,06). Concluiu-se que o tratamento de defeitos infra-ósseos com RET associado à PME não mostrou resultados melhores que o uso de RET sozinho.

OBJETIVOS: verificar as condições periodontais e necessidade de tratamento fornecidas pelo Registro Periodontal Simplificado (PSR) em puérperas, com o intuito de contribuir ao esclarecimento da relação entre doença periodontal e nascimento de recém-nascidos prematuros de baixo peso. MÉTODOS: foi empregado o PSR em amostra de 40 puérperas, divididas em: grupo 1 (teste), composto pelas mães de recém-nascidos prematuros com peso inferior a 2.500 g (n=20), e grupo 2 (controle), formado por mães de recém-nascidos a termo com peso igual ou superior a 2.500 g (n=20). Os dados coletados foram analisados por meio de estatística descritiva, sendo os resultados do PSR submetidos ao tratamento estatístico para verificar se existem diferenças na condição periodontal e necessidade de tratamento entre as puérperas, sendo empregado o teste de Kolmogorov-Smirnov, em nível de significância de 5%. RESULTADOS: a presença de bolsa periodontal de 3,5 a 5,5 mm foi o achado mais comum entre as puérperas de recém-nascidos de baixo peso (39,17% dos sextantes), ao passo que a presença de sangramento à sondagem e ausência de bolsa periodontal foram os achados mais freqüentes entre as puérperas de recém-nascidos com peso normal (37,50% dos sextantes), havendo diferença significativa na condição periodontal das puérperas (p=0,0494). Quanto à necessidade de tratamento, não houve diferença significativa entre os grupos estudados (p>0,05). CONCLUSÕES: as puérperas de recém-nascidos prematuros com baixo peso apresentaram piores condições periodontais, sugerindo que a infecção periodontal pode estar relacionada ao nascimento de recém-nascidos prematuros de baixo peso.PURPOSE: to evaluate periodontal conditions and need for treatment supplied by Periodontal Screening and Recording (PSR) in mothers, in order to clarify the relationship between periodontal disease and low birth weight premature newborns. METHODS: PSR was used in a sample of 40 mothers, divided into: test group, consisting of mothers of premature newborns with weight less than 2,500 g (n=20), and the control group, consisting of mothers of term newborns with a weight equal to or over 2,500 g (n=20). The collected data were analyzed by descriptive statistics, and the results of PSR were submitted to statistical analysis in order to verify differences in periodontal condition and need for treatment of the mothers, using the Kolmogorov-Smirnov test, with a significance level of 5%. RESULTS: the presence of periodontal pocket of 3.5 to 5.5 mm was the most common finding among the mothers of newborns with low weight (39.2% of the cases), while the presence of bleeding at probing and absence of a periodontal pocket were the most frequent findings among the mothers of newborns with normal weight (37.5% of the cases). There was a statistically significant difference between periodontal conditions of the mothers of the groups (p=0.0494), but in relation to the need for treatment, there was no significant difference between the studied groups (p>0.05). CONCLUSION: the mothers of preterm newborns with low weight presented worse periodontal conditions, suggesting that periodontal infection may be related to preterm low birth weight newborns.

Root debridement generates a smear layer which contains microorganisms and toxins that could interfere in periodontal healing. For this reason, different substances have been used to remove it and to expose collagen fibers at the tooth surface. Blood element adhesion to demineralized roots and clot stabilization by collagen fibers are extremely important for the success of periodontal surgery. The aim of this study was to evaluate the different patterns of blood element adsorption and adhesion to root surfaces only irrigated with distilled water and after application of a manipulated or an industrialized EDTA gel. Thirty samples were planed, equally divided into three groups and treated with distilled water (control), a manipulated EDTA gel or an industrialized one. Immediately after, samples were exposed to fresh blood and prepared for scanning electron microscopy. Untreated planed dentin presented the best results with blood cells entrapped in a thick web of fibrin. In the manipulated EDTA group, the web of fibrin was thick with sparse blood elements. The worst result was seen with the industrialized EDTA group, in which no blood elements could be seen. Statistical difference was obtained between control and industrialized EDTA groups. Surfaces only irrigated presented the most organized fibrin network and cell entrapment.A raspagem gera "smear layer", a qual contém microrganismos e toxinas que podem interferir no reparo periodontal. Por esse motivo, diferentes substâncias têm sido empregadas para remover esta camada e expor fibras colágenas da superfície dental. A adesão de elementos sangüíneos a superfícies radiculares desmineralizadas e a estabilização do colágeno pelas fibras colágenas são de extrema importância no sucesso da cirurgia periodontal. O objetivo deste estudo foi avaliar os diferentes padrões de adsorção e adesão de elementos sangüíneos a superfícies radiculares apenas irrigadas com água destilada e após aplicação de um gel de EDTA manipulado ou um industrializado. Trinta amostras foram raspadas, eqüitativamente divididas em 3 grupos e tratadas com água destilada (controle), um gel de EDTA manipulado ou um industrializado. Imediatamente foram expostas a sangue fresco e preparadas para microscopia eletrônica de varredura. As superfícies dentinárias apenas raspadas apresentaram os melhores resultados, com moderada quantidade de células sangüíneas entremeadas em uma fina rede de fibrina. No grupo de EDTA manipulado, a rede de fibrina foi pouco visível com escassas células. Os piores resultados foram observados com o EDTA industrializado, caracterizados pela ausência de elementos sangüíneos. Estatisticamente houve diferença apenas entre os grupos controle e EDTA industrializado. As superfícies apenas irrigadas apresentaram rede de fibrina mais bem organizada com células entremeadas.
