The multifactorial etiology of periodontal disease and pulp processes, the bacterial factor has great relevance. In these processes is identified polymicrobial flora which highlights Treponema denticola, a spirochete with multiple virulence factors that make it a dangerous bacterium, being identified with a certain predominance in lesions as gingivitis necrotizing ulcer and acute apical abscesses. Its isolation culture is feasible by highly enriched media, although based procedures such as molecular biology PCR (polymerase chain reaction) can determine its presence and quantity. This review aims to tell us more about this pathogen.

Aggregatibacter actinomycetemcomitans is a pathogen extensively studied in the clinical conditions of the Periodontitis, already identified in the early twentieth century. Over the years it has undergone changes in its denomination and multiple virulence factors that make it an important pathogen in the periodontal disease have been discovered, specifically in the localized Aggressive Periodontitis. This review tries to explain its morphology, virulence factors, culture and other important characteristics.

Porphyromonas gingivales es un bacilo gram negativo predominante en la Periodontitis crónica, sus múltiples factores de virulencia la hacen sumamente agresiva. En el surco gingival encuentra las condiciones para su crecimiento, interaccionando con el huésped produciendo una destrucción lenta pero constante de los tejidos del periodonto. Su predominancia ha sido considerada como un factor de riesgos para enfermedades sistémicas inflamatorios, como la del infarto de miocardio. Aunque su susceptibilidad a una diversidad de fármacos hace posible su manejo con antimicrobianos previa remoción mecánica de biofilm subgingival. En conclusión la revisión abarca diversas características de la bacteria, que nos unen al consenso de que Porphyromonas gingivalis es el patógeno de mayor relevancia en la periodontitis crónica, así como su presencia en diversas formas de patologías periodon...

The deficiencies of bone quality in the patient, either of wide or height, make the clinician take decisions to improve these conditions, with the purpose of placing implants or improving faulty edges that can support a prosthetics frame. For this, the procedures of guided bone regeneration with ones own chin bone (autogenous implant), are the ones with the best forecast for resolving the problem. In this clinical case we show the diagnosis, the surgical technique, the advantages and pharmacotherapy of guided bone regeneration treatment with autogenous chin implant.

One of the tumours in the oral cavity of epithelial origin, with major damage at the bone or soft tissue is an Ameloblastom; although this is a benign tumour, its aggressiveness could lead to produce extensive destruction of the jawbone. In this report, one case is exposed, a male patient with clinical and diagnosis - X-ray radiographicof Ameloblastom.

Objective: the objective of this study was to evaluate the antibacterial activity of oleoresin Copaifera reticulate (C. reticulata) on Periodontopathogenic bacteria Porphyromonas gingivalis (P. gingivalis ) Methodology: From a total of 43 samples of subgingival plaques of patients with periodontitis, it was isolated 20 clinical strains of P. gingivalis, the preliminary identification occurred by growth of black pigmented colonies on blood agar with hemin and vitamin K, these colonies were purified to test for catalase, oxidase and TSI, Citrate, Urea, Sim means. Definitive identification was held by means of the automated testing of Api 20 A. Once the strain were isolated the diffusion test was performed on plate, with discs loaded with the oleoresin at concentrations of 100 %, 50 %, 25 %, 12,5 %, 6,25 %, 3,12 %, 1,56 %, 0.78%, 0,39 %, 0,19 %, taking 0,12 % chlorhexidine as a positive con...

The renowned Dr. Antonio Bascones Martínez, represents an exponent of contemporary dentistry, his knowledge and experience offered in his classes; make him the epitome of this profession. At 74 years old, he reminds us of the ever-changing evolution of dentistry. In this interview we want to recollect his story, inspiration, highlight his abundant knowledge and regard him as the teacher he is.

El Dr. Mario Julio Avila Campos, falleció el 28 de abril del 2019 en Sao Paulo, Brasil, hombre estudioso dedicado a conocer la microbiología anaerobia bucal, dejando múltiples investigaciones que sirvieron de base para otras, así como los conocimientos que nos permitió comprender mejor la fisiopatología de muchas bacterias periodontopatógenas. Su laboratorio de anaerobios del Instituto de Ciencias Biomédicas de la Universidad de Sao Paulo (ICB-USP) donde laboró hasta sus últimos días, pudo recibir a muchos estudiantes de pre y posgrado de diferentes nacionalidades, entre ellos peruanos que se formaron allí, teniendo apoyo para el desarrollo de sus proyectos de investigación.

Among the microorganisms that form the red complex, considered by Socransky as aggressive bacteria in periodontitis, such as Tannerella forsythia, a strict anaerobic bacillus, which would be participating with relevance in this pathology, its multiple virulence factors, as well as its capacity to subsist under optimal conditions in the periodontal pocket, such as stimulating the activation of inflammation mediators that with the chronicity of the disease would be progressively damaging the periodontium. In this review, we will learn more regarding this microorganism of great importance in periodontal diseases.

Porphyromonas gingivalis is a gram negative bacillus predominant in chronic periodontitis, multiple virulence factors make it extremely aggressive. In the gingival sulcus find the conditions for growth,interacting with the host produces a slow but steady destruction of periodontal tissue. Its dominance has been considered a risk factor for systemic inflammatory diseases such as myocardial infarction. Although its susceptibility to a variety of drugs makes possible its handling with antimicrobials after mechanical removal of subgingival biofilm. In conclusion this review covers various features of the bacteria, which lead us to the consensus that the pathogen Porphyromonas gingivalis is more relevant in chronic periodontitis,and its presence in various forms of periodontal diseases

Aggregatibacter actinomycetemcomitans (A.a) es un patógeno muy estudiado en los cuadros clínicos de periodontitis. Esta bacteria ya fue identificada a principios del siglo XX. Con los años ha ido cambiando de nombre y se han descubierto múltiples factores de virulencia que la hacen un patógeno importante en la enfermedad periodontal, especificado en la periodontitis agresiva localizada. Esta revisión tratará de explicar sus características más importantes, que la hacen una bacteria muy evolucionada.
