It is demonstrated the efforts made endodontic microbiology and science to get to decipher the secrets of this unique structure although every day new questions arise. We need the treatments we use to combat biofilm achieve oxygenate the periapical ecosystem and basically scrape and loosen the tightly adhering bacteria Knowing the process of biofilm formation, microbial metabolism and strategies that they use to resist and remain hidden but active , we know why we observe refractory periapical lesions.

With the objetive of detennine the helicobacter pylori (Hp) prevsalencv in patiens with gingivitis and periodontal disease, it was collected and processed sullgingival plate samples from 177 patients whose have been classffied according to: 1) Ulcer and gingivitis, 2) gastritis and gingivitis, 3) gingivitis and 4) periodontitis aleatoriamente selected at the Odontological Clinic! of San Marcos University It was recovered Hp in 9,4%ftom the studied poblation, tnoreftecuenilly in women (6,8%) than in men (2,6 %). Helicobacerpylori was recovered.front the 7,7 % qfpatients with giligivitis, and from the 1,7% of patients with gastritis and gingivitis. Principally Hp was recovered neither from patients with ulcer and gingivitis nor patienty with periodontitis. principally Hp was recovered form people between 20 and 30 years old, and more frecuently in womwn than in men.

The purpose of this case is to show the use of intracanal medication Oshino paste (3Mix-MP). A patient who had a pulp necrosis with chronic apical periodontitis in the piece 42, underwent endodontic treatment in 2013, but in 2014 returns with a more severe apical lesion and the diagnosis of apical periodontitis, extra oral fistula; the patient did not want to lose the tooth so that the possibility of nonsurgical treatment of second intention using paste 3 MIX-MP as intracanal medication was evaluated. Controls for 3 months with intracanal medication were performed, the clinical disappearance of fistula was observed and periapical lesion decrease, improving the prognosis. So we proceed to seal the tooth and evaluated for 12 months, coming to observe bone repair, then the prosthetic restoration of the piece was done.

El propósito de este caso clínico es mostrar el uso como medicación intraconducto de la pasta de Hoshino (3Mix-MP). Paciente de sexo femenino acude a la clínica de posgrado con el diagnóstico clínico de necrosis pulpar con periodontitis apical crónica de la pieza 42. Se le realizó un tratamiento endodóntico en el año 2013; en el año 2014 regresa con lesión apical más severa y con un diagnóstico de periodontitis apical con fístula extraoral. La paciente no desea perder la pieza dentaria, por lo que se evalúa la posibilidad de tratamiento de segunda intención no quirúrgica utilizando la pasta de 3 MIX-MP como medicación intraconducto. Se realizaron controles por 3 meses con medicación intraconducto, clínicamente se evaluó la desaparición de la fístula observándose radiográficamente la disminución de la lesión periapical mejorando el pronóstico, por lo que se pr...

En base a los resultados obtenidos sobre el hallazgo de Helicobacter pylori en los estudios precedentes, en Placa Dental, y en pacientes con gi. ngivitis y enfermedad periodontal, (Moronn, 1999 y 2000, respectivamente), se considero necesario implementar este proyecto, mediante la determinación de los niveles de infección a través de la presencia de anticuerpos específicos. En este caso el estudio abarcará una población de estudio más amplia, constituida por una muestra poblacional de estudiantes de In Facultad de Odontología de la Universidad de San Marcos, con el objeto de conocer la situación estudiantil respecto al nivel de anticuerpos contra Helicobacterpylori.

Bioethics arises from the need to respond and try to solve the major conflicts that arise in society. Bioethics is a modern term that is attributed paternity Van Rensselaer Potter (1970) by publishing the article “Bioethics, the science of survival,” Potter establishes the existence of a close relationship between the world of life sciences, his deeds and ethical values, bioethics subsequently primarily it related to medical ethics. Tom L. Beauchamp and James F. Childress published “Principles of biomedical ethics” 1979, being considered a classic text in biomedical ethics, in which four bioethical principles states: autonomy, non-maleficence, beneficence and justice. Analysis and bioethical reflection are essential in the practice of the dentist, this will allow a clinical practice based on values, which would involve all health personnel, guiding strategies to address adequatel...

The purpose of the investigation was, to compare the marginal seal of direct restorations, carried out with the sandwich technique, after the removal of decayed tissue by means of papaine gel (Papacarie) and the conventional rotational method. So, 20 recently extracted human premolars were selected, with decay lesions that committed the oclusal and proximal surface. The sample was randomly divided in two groups: Group 1: the removal of decayed dentine was made, by means of the chemo mechanical technique using the gel Papacarie. Group 2: the removal of decayed dentine was made by means of the conventional technique, using rotational instruments. After the removal of decayed tissues by both techniques a direct restoration was placed using the sandwich technique, placement of glass ionomer modified by resin, adhesive system of a single step and micro hybrid composite resin. Then, after term...
