“…Nevertheless, only the work of Yilmaz et al demonstrated different results (12). They revealed that the teeth filled using the combined system had a higher leakage than the single-cone group.…”

Forty two single-rooted teeth, preparedwith the Mtwo system, were divided into three groups based on the filling method: control, "Single-cone" (n = 20) (Mtwo gutta-percha single-cone tapered according to the diameter, length and conicity of the preparation) and "Combined system" (n = 20) (BeeFill 2in1). The parameters studied were apical leakage, gutta-percha adjustment, number of voids, presence/absence of sealer, root canal morphology, residual fragments, and filling of lateral/accessory canals. A dye penetration test was carried out (methylene blue). The teeth were embedded in resin, cut transversally and observed. The data were analyzed with non-parametric Mann-Whitney and Spearman tests. Comparative tests between the two groups showed that the "Combined system" was superior in terms of apical leakage (P < 0.01), gutta-percha adjustment (P < 0.05) and filling of lateral/accessory canals (P < 0.05). There were statistically significant correlations between master cone adjustment and root canal morphology (P < 0.01) in the "Single-cone" group. In the "Combined system" group, a relation was observed between the voids and root canal morphology (P < 0.05) and between voids and residual fragments (P < 0.05). The quality of obturation with warm gutta-percha was better than that of the tapered single-cone technique. Root canal morphology influences gutta-percha adjustment. Residual fragments on the root canal reduce sealing ability. (J Oral Sci 54, 99-104, 2012)

“…Researchers have examined these techniques in terms of issues such as sealing ability (25-27), caused to root strains (23), and the effect of resistance to vertical fracture (12). In this study, which evaluated the effects of filling techniques that include different procedures on vertical fracture resistance, it was found that there is no statistically significant difference between the filling techniques, and that these techniques cannot form a resistance to vertical fracture (p>0.05).…”

Objectives: The aim of this study was to compare in vitro root fracture resistance following root canal filling with AH 26 using lateral condensation, BeeFill, and Thermafil techniques. Study Design: Eighty extracted human mandibular premolars with similar dimensions were selected. In order to standardize the roots, measurements were taken in two separate regions of the teeth—at the cemento-enamel junction and 8 mm apically from the junction—buccolingual as well as mesiodistal for every tooth. Teeth were then randomly divided into five groups (n=16). With the exception of the non-prepared group (Group 1), instrumentation was done in all groups. In group 2, instrumentation but no filling was performed; in group 3, the obturation was done with AH 26 + gutta-percha; in group 4, with AH 26 + BeeFill and in group 5, AH 26 + a Thermafil obturator was used. All the roots were mounted vertically in copper rings and filled with acrylic resin, exposing 8 mm of the coronal part. A universal testing machine was used for the strength test. Results: The results were analyzed using the one-way ANOVA test. The significance between the groups was tested with Temhane’s T2 test. The results indicate that instrumentation of root canals had a significant effect on fracture resistance (p<0.05). In addition, there were no differences between the root canal obturation techniques; furthermore, these techniques did not create a statistically important resistance to vertical fracture (p>0.05). Conclusions: The results suggest that instrumentation of root canals significantly weakens the tooth structure to fracture and the root canal obturation techniques that are used are not able to form reinforcement. Key words:AH 26, obturation technique, vertical fracture.

“…Nuestro estudio mediante la observación a través del microscopio estereoscópico demostró una mejor calidad de obturación observándose un sellado tridimensional, sin presencia de vacíos y poco cemento en la interfase con la dentina con la técnica de obturación de onda continua Beefill 2en1, estos estudios son consistentes con los estudios realizados por Lieven Robberecht 1 , calentando y atacando la gutapercha permite la realización de una obturación que se adapta mejor al sistema de conductos radiculares, que aumenta el ajuste apical y propulsa el cemento sellador a las variaciones anatómicas, que coincide con los resultados obtenidos por un estudio similar realizado por Yilmaz 11 . Considerando que la calidad del sellado apical del material obturador a la pared del conducto es un factor importante para determinar el sellado tridimensional y hermético que previene la proliferación bacteriana, los resultados obtenidos en el estudio de Maniglia Ferreira Según el estudio realizado por Hüse-yin 13 en la técnica en frio de condensación lateral el cemento sella el mayor porcentaje del conducto radicular, este cemento es frágil por lo tanto es más susceptible a la solubilización resultando en fallas.…”

Comparación de la calidad de sellado de tres técnicas de obturación radicular a través del microscopio estereoscópicoComparison of sealing quality of three root canal filling techniques through stereoscopic microscope Resumen Objetivo: Este estudio es una evaluación in vitro del sellado tridimensional del sistema de conductos radiculares realizados con tres técnicas de obturación: Condensación Lateral, Técnica Hibrida de Tagger y Termoplástica con Beefill 2 en 1, por tercios radiculares en dientes inferiores. Metodología: Se utilizaron 30 primeras premolares inferiores las cuales fueron divididas aleatoriamente en tres grupos de 10 para cada técnica de obturación. Se realizó la limpieza, desinfección y conformación del conducto radicular. Para la técnica Condensación Lateral y Beefill 2 en 1 se prepararon con el Sistema Mtwo, y para la técnica híbrida de Tagger se preparó con la técnica Crown Down de la Universidad de Oregon. Se obturaron las muestras y se realizaron cortes transversales en tercio cervical (3 mm), medio (6 mm) y apical (9mm), y fueron llevados al microscopio estereoscópico. Resultados: Se realizó el análisis estadís-tico del Chi cuadrado y la prueba de comparación de proporciones con el test Z nivel de significancia del 5%.Grupo 3 (condensación lateral) grupo 2 (Hibrida de Tagger) grupo 1 (Beefill 2 en 1). A nivel del tercio cervical no hubo diferencias estadísticamente significativa entre los tres sistemas, X 2 =3.36, p=0.186, se evidenció la presencia de vacíos solo en los grupos 2 y 3. A nivel del tercio medio X 2 =6.67 encontrándose diferencias estadísticamente significativa en la calidad del sellado de Beefill con respecto a los otros p=0.036. A nivel del tercio apical X 2 =8.9 encontrándose diferencias estadísticamente significativa en la calidad del sellado de Beefill con respecto a los otros p=0.014. Posteriormente se realizó la prueba de comparación de proporciones con el test Z confirmándose la significancia de los hallazgos La técnica termoplástica con Beefill 2 en 1, demostró una calidad de sellado óptimo, en los tres tercios observándose diferencias estadísticamente significativas en el tercio medio y apical p<0.05.Conclusión: La técnica termoplástica de ola continua con Beefill 2 en 1 presenta mejor calidad de sellado en los tres tercios, pues al ablandar la gutapercha por calor y al ser compactada, esta discurre por todo el conducto radicular.Palabras clave: Calidad de sellado; Técnica de obturación radicular; Beefill; Tagger; Condensación lateral.
