A periodontite agressiva (PAg) acomete indivíduos clinicamente saudáveis, exceto pela presença da doença periodontal, caracterizando-se por rápida perda de inserção e destruição óssea e ainda pela agregação familiar, dentre outras características secundárias. A rápida destruição periodontal presente na PAg é um fator de extrema importância e desperta a atenção de pesquisadores em todo o mundo, uma vez que se deparam com uma infecção caracterizada por uma microbiota altamente virulenta e/ou um alto nível de susceptibilidade do indivíduo. O risco de perdas dentárias e comprometimento da função e estética, principalmente em pacientes jovens, mais comumente acometidos pela PAg, também estimulam a busca por respostas e tratamentos mais eficientes no controle da doença. Diante disso, o objetivo deste trabalho foi realizar uma revisão de literatura sobre a periodontite agressiva abordando as descobertas sobre a etiologia microbiana e susceptibilidade do indivíduo, assim como sua resposta às diferentes abordagens terapêuticas.

This paper aims to evaluate the effects of smoking on periodontal microsurgery technique using the subepithelial connective tissue graft (SCTG) for treatment of gingival recession on smokers. 14 patients nonsmokers and 12 smokers were selected, presenting Miller’s Class I and II gingival recession ≥ 2.0 mm. For both groups, the subepithelial connective tissue graft was used with the aid of a surgical microscope. The clinical parameters of width and height of the gingival recession, height and thickness of keratinized tissue, probing depth and clinical attachment level were evaluated before and six months after surgery. At the end of the study, there were obtained an average percentage of 96.66% of root coverage on nonsmokers and 82.49% on smokers (p=0.03). Complete root coverage was observed in 78,57% and 50% of patients, respectively. Therapy can benefit both groups, but smokers have less favorable outcomes to root coverage with periodontal microsurgery using the SCTG.

O tratamento da recessão gengival é normalmente um recontorno da arquitetura gengival, com ou sem associação de técnicas, para alcançar o recobrimento da superfície radicular exposta e aumentar a quantidade de tecido queratinizado. Estes procedimentos visam a uma melhoria estética e tratamento da hipersensibilidade dentinária, assim como a redução do risco de cárie. O retalho posicionado coronalmente é uma técnica muito utilizada para realização de recobrimento radicular. Na literatura, têm sido relatados diversos fatores que podem interferir no sucesso dessa técnica, dentre os quais estão os relacionados ao tecido periodontal, à técnica cirúrgica e aos hábitos dos pacientes. O objetivo desse artigo foi reunir os fatores que poderiam influenciar no resultado final da técnica de retalho posicionado coronalmente, mediante uma revisão de literatura. AbstractGingival recession is defined as the migration of the gingival margin apical to the cemento-enamel junction and can be caused by bacterial biofilms, primary etiological factor of periodontal inflammation, as well as the trauma of brushing. The treatment is usually a recontouring of the gingival architecture with or without associated techniques to achieve the covering of the exposed root surface and increase the amount of keratinized tissue. These procedures aim to an aesthetic improvement and treatment of dentin hypersensitivity as well as reducing the risk of caries. The coronally positioned flap is a technique widely used for achieving root coverage. The

The aggressive periodontitis (AgP) occurs on clinically health individuals, except for the presence of periodontal disease, is characterized by rapid attachment loss and bone destruction and also by family aggregation, among other secondary characteristics.  The rapid periodontal destruction observed in AgP is an extremely important factor and have raised the researchers attention all over the world, once one come across an infection characterized by a highly virulent microorganism and/or by highly susceptible individuals. The risk of tooth loss and function and esthetic compromising, mainly in young patients, more commonly affected by the AgP, also stimulates the search for answers and more efficient treatments in the disease control. Therefore, the aim of this study is to review the literature of aggressive periodontitis considering the findings in the microbial etiology and individual susceptibility, as well as its response to periodontal therapy and the search for alternatives that lead to benefits in the periodontal clinical parameters.

Gingival recession is defined as the migration of the gingival margin apical to the cemento-enamel junction and can be caused by bacterial biofilms, primary etiological factor of periodontal inflammation, as well as the trauma of brushing. The treatment is usually a recontouring of the gingival architecture with or without associated techniques to achieve the covering of the exposed root surface and increase the amount of keratinized tissue. These procedures aim to an aesthetic improvement and treatment of dentin hypersensitivity as well as reducing the risk of caries. The coronally positioned flap is a technique widely used for achieving root coverage. The literature have reported several factors that can interfere with the success of this technique, among which are those related to periodontal tissue, the surgical technique and patient’s habits. The aim of this article was to getter the factors that could influence the outcome of coronally positioned flap technique, through a literature review.
