El objetivo de esta investigación fue evaluar ”in vitro” la actividad antibacteriana de dos pastas: 3 Mix-MP y Calen PMCC® como medicación intraconducto en un biofilm formado por 3 cepas: Porphyromona Gingivalis, Enterococcus Faecalis y Peptostreptococcus Anaerobius, presentes en Periodontis apical crónica; se utilizaron 32 piezas dentarias (premolares) a las cuales se les aplicó el mismo protocolo: fueron instrumentadas con sistema Mtwo hasta la lima 40.04, luego 22 piezas fueron seccionadas mesiodistalmente y 10 no seccionadas, fueron esterilizadas y contaminadas manteniéndolas en caldo BHI vitaminado por un lapso de 7 días. El proceso se dividió en 2 fases: en la primera fase se usaron 12 piezas seccionadas; a las que se les hizo el raspado en toda la superficie sembrándose en Agar Shaedler por 7 días; luego se realizaron 4 pozos de 5mm de diámetro por cada placa donde ...

Aim: To compare the sealing capacity of mineral trioxide (MTA®) and tricalcium silicate (Biodentine®) for retrograde filling in single-root permanent teeth. Materials and methods: Thirty-eight permanent single-root teeth with complete apical closure were selected and randomly divided into two experimental groups (n = 15): Group 1: MTA®, and Group 2: Biodentine®, in addition to positive and negative controls. Root treatment was performed with the MTWO rotary system, and obturation was carried out by means of the continuous wave thermoplastic system (Beefill) using Grossman-type cement as a sealant. Apical end apicoectomy was performed followed by the preparation of standardized retro-apical cavities and the respective fillings with MTA ® and Biodentine® according to the study group. Subsequently, the specimens were subjected to an apical filtration process of Chinese ink and transpa...

Objective: the objective of this study was to determine and analyze the wettability of irrigating solutions of root canal treatment in bovine tooth dentin surface. Materials and method: For the study were prepared 15 acrylic blocks :40 mm x 30 mm x 8 mm wherein a surface exposed tooth dentin of bovine tissue. There were used as test irrigants: 5,25% sodium hypochlorite solution, 0,12% chlorhexidine gluconate, water saturated with calcium hydroxide and sodium chloride solution 9/1000. On dentin surface was deposited a calibrated drop of irrigating solution, this sessile drop contact with dentin surface showed many forms which were photographed to measure them with a conveyor provided the angle (contact angle). Results showed that Chlorhexidine Gluconate 0,12 %, established a contact angle with an average of 41.33°, followed by water saturated with calcium hydroxide (43.23º), sodium hypo...

Objetivo: Determinar y analizar la capacidad de humectancia de soluciones irrigantes usadas en el tratamiento de conductos radiculares sobre la superficie dentinaria de dientes de bovino. Materiales y método: Estudio experimental in vitro. Se preparó 60 bloques de acrílicoautocurado de 40 mm x 30 mm x 8 mm donde una superficie expone tejido dentinario de diente de bovino.

En la superficie de dentina se depositó una gota calibrada de las soluciones irrigantes, estas gotas sésiles en contacto con dentina mostraron muchas formas las cuales fueron foto-grafiadas para posteriormente superponerle el trazo de una tangente desde el punto de contacto y sobre el ecuador del arco establecido, el ángulo resultante fue medido con un transportador esta...

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.

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...

Objectives: Compare the degree of apical microleakage using three filling techniques: lateral condensa-tion, single cone and a new proposed technique. Materials and method: 36 teeth were prepared with rotary files Mtwo until Nº. 40 / .04 and then be randomly selected using three obturation techniques (G1: lateral condensation technique, G2: single cone; G3: new proposed technique). Subsequently, the teeth are varnished exposing the apical 4mm, dipped in ink and those undergoing the decalcification process following the Protocol of Roberston and measured seepage through a stereoscopic microscope. Comparisons were made with the Kruskal Wallis test. Results: The new proposed technique had a lower rate of microfiltration comparing the lateral condensation technique and single cone. No statistically significant differences between the three obturation techniques. Conclusions: The apical micr...

Objetivos: Comparar el grado de microfiltración apical utilizando tres técnicas de obturación. Materiales y método: 36 piezas dentarias fueron preparadas con limas rotatorias Mtwo hasta N° 40/.04 para luego ser seleccionadas aleatoriamente utilizando tres técnicas de obturación (G1: técnica de conden-sación lateral; G2: cono único; G3: nueva técnica propuesta). Posteriormente, las piezas dentarias se barnizaron exponiendo los 4mm apicales, se sumergieron en tinta china y se sometieron al proceso de descalcificación siguiendo el protocolo de Roberston, y se midió la filtración a través del microscopio estereoscópico. Las comparaciones fueron realizadas con la prueba de Kruskal Wallis. Resultados: Las medias en los tres grupos fueron: G1= 0,17±0,21 mm, G2 = 0,34±0,49 mm y G3 = 0,14±0,21 mm. Siendo de menor medida el grupo que se obturó con la nueva técnica propuesta. C...

This treatment was carried out in a 58 years old male patient, who has had the antecedent of a car crash accident two years before; he loosed several teeth and fractured others. Pulp necrosis and alteration of occlusal plane occurred. Because of the pathologies presented, it was installed a multidisciplinary treatment phase having periodontal, endodontic, surgical and orthodontic procedures, tehe installation of posts, crowns and fixed bridges. Treatment was carried out for five months.

The Odontogenic Peripheral Fibroma is the most frequent form of Odontogenic Fibromas and seems to come from the superficial gingival epithelium or dental lamina residuals that remain in an extra bone location. The epithelial component resembles the dental lamina during the early stages of the odontogenesis. Although it has predilection for children and young adults, it can be presented in any age. It is most often observed in women than men.

Objective: This research aims to analyze the knowledge, application and assessment about the Information and Communication Technology (ICT) of Web 2.0 in education.
