An unacceptable level of microleakage can lead to failure. Objectives: To compare apical microleakage in single rooted teeth root filled with thermoplastified gutta-percha and lateral condensation using two cementing mediums. Materials and Methods: Experimental in vitro study of 144 teeth. Inclusion criteria: extracted single rooted teeth due to orthodontic reasons, complete root formation. Exclusion criteria: teeth with resorptions, dilacerations, fractures, calcific metamorphoses or open apices. Previous patient informed consent teeth were randomly distributed into six groups: group 1 (lateral condensation and Guttaflow), group 2 (thermoplastified and Guttaflow), group 3 (lateral condensation and Topseal), group 4 (thermoplastified and Topseal), group 5 (positive control), which were then decoronated, instrumented and root filled by a calibrated operator at 14mm with Pro Taper rotary system up to the F3 finishing file. Teeth were made impermeable except 3mm atthe root apex and were submerged in a methelyne blue dye. Apical leakage under the stereomicroscope at 24 hours, 15, 30, and 45 days was evaluated. Results: All groups showed a tendency to increase microleakage by 30 days and decrease by 45 days. The control group showed the greatest microleakage, the other groups showed no statistical difference 1,30 and 45 days, the group 3 showed statistical difference p=0.022 with control after 15 days.Conclusion: The Top Seal® cement was the cementing medium that obtained the lowest levels of microleakage by means of lateral condensation, as well as the highest levels of microleakage by means ofthermo-plastification. The use of Guttaflow® as the cementing medium showed similar results to the use of the Top Seal® cement, without a statistically significant differenceContexto: La obturaddn del conducto radicular con gutapercha requiere de un medio cementante para lograr un selle herm6tico. Un nivel de microfiltracion inaceptable (leva al fracaso del tratamiento endodontico Objetivo: Comparar la microfiltraddn apical en dientes unirradiculares obturados con gutapercha termoplastificada y condensacidn lateral utilizando dos medios cementantes.Materiales y Mdtodos: Estudio experimental paralelo in vitro de 144 dientes. Criterios de inclusidn dientes unirradiculares extraldos con fines ortodonticos, con formaddn radicular completa. Criterios de exclusidn dientes con reabsordones, dilaceraciones, fracturas, metamorfosis cdldca o Spices abiertos. Previo consentimiento informado por parte del paciente, los dientes fueron distribuidos aleatoriamente en dnco grupos: grupo 1 (condensacidn lateral, Gutafflow), grupo 2 (termoplastificada, Gutafflow), grupo 3 (condensacidn lateral, topseal),grupo 4 (termoplastificada, Topseal), grupo 5 ( control positive), los cuales fueron decoronados,instrumentados y obturados por un operador calibrado a 14mm con sistema rotatorio Protaper hasta F3. Los dientes fueron impermeabilizados exceptuando los 3mm apicales y fueron sumergidos en un tinte de azul de metileno para medir la microfiltraddn bajo el estereomicrocospio a las 24 horas, 15,30 y 45 dlas. Resultados: Los grupos presentaron una tendencia de aumentar la microfiltraddn hasta los 30 dias y disminuir a los 45 dlas. El grupo control fue el que presento mayor fiftradon, los otros grupos no presentaron diferencia estadisticamente a 1,30 y 45 dias, el grupo3 presento diferencia estadisticamente significativa con p=0.022 con el control a los 15 dias. Conclusiones:.EI cemento Top Seal® fue el cemento sellador que obtuvo los niveles mas bajos de microfiltraddn en la tecnica de condensacidn lateral y mas altos en la tdcnica termoplastificada. Al utilizar el material Guttaflow® como medio cementante este se comporto muy similar al cemento Top Seal® sin diferencia estadisticamente significativa64 pp,application/pdfesmicrofiltraddn apicalGutafflowTecnicas de obturaddncemento selladorInvestigación de campotext::thesis::bachelor thesisTEN 00068apical microleakgeGuttaflowobturation techniquessealing cementopenAccess
