A clinical trial of cold lateral compaction with Obtura II technique in root canal obturation

Abstract

Introduction:The purpose of obturation of the prepared root canal space is to prevent coronal leakage and bacterial contamination and to seal the apex from the periapical tissue fluids. Cold lateral technique has been considered to be a gold standard, however considering its limitations various thermoplasticized gutta-percha techniques have been recommended. This study compares radiographic quality of obturation in molar teeth, obturated with cold lateral condensation and thermoplasticized injectable gutta-percha technique (Obtura II system).Materials and Methods:Sixty patients were equally divided into two groups, Group A obturated with Cold lateral condensation technique and group B with Obtura II. Periapical radiographs were obtained immediately after the obturation using paralleling device method. The radiographs were examined by an observer, who was blinded to the group allocation. Data was compared using χ2 (Chi square) test and Independent sample t test was used to compare the mean ages.Results:Both groups were comparable in all respects such as tooth type, preoperative diagnosis and preoperative pain (P>0.05); however, more pre-operative radiolucency cases were allocated to Obtura II (P<0.05). There was no difference between the two groups, both in terms of postoperative voids as well as apical termination of the obturation (P>0.05).Conclusion:Within the limitations of the study, it was found that statistically there was no significant difference between cold lateral and obtura II technique, in terms of post obturation voids and apical termination, as observed in radiographs.

The Comparison of Apical Leakage between Two Obturation Techniques (Cold Lateral Condensation and Obtura II) by Using Fluid Filtration Method

“…Cold lateral condensation technique and Obtura II have also compared in clinical studies. Ansari et al (18) concluded that there is no significant difference between these two techniques regarding voids and apical termination.…”

Coronal Microleakage Of Enterococcus Faecalis In Three Types Of Endodontic Filling (Warm Vertical Compaction, Lateral Compaction, And Single Cone)

“…1 Lateral compaction does not meet the requirement of providing homogeneous sealing of the root canal, unlike the warm vertical compaction technique, which provides homogeneous sealing allowing adaptation of material to the walls, and even sealing root canal irregularities. 5,6 The cold single-cone technique, on the contrary, is being widely used nowadays due to its simplicity and low cost, even though it does not provide a threedimensional sealing of the root canal, in contrast to the evidence, which has demonstrated that this technique has high failure rates due to poor sealing. [7][8][9][10] Dye penetration and microbial filtration are the two most common methods to evaluate microleakage of endodontic obturations, 11 but microbial filtration is the most relevant method, since it fits clinical conditions.…”

“…1 La compactación lateral no cumple el requisito de generar un sellado homogéneo del conducto radicular, contrario a la técnica de compactación vertical caliente, la cual logra un sellado homogéneo que permite la adaptación del material a las paredes, sellando incluso las irregularidades en el conducto. 5,6 La técnica de cono único en frío, por el contrario, está siendo ampliamente usada en nuestro medio debido a su facilidad y bajos costos, sin importar que se logre o no el sellado tridimensional del conducto radicular, lo cual va en contraposición a la evidencia, que ha demostrado que esta técnica presenta altos índices de fracaso debido a su falta de sellado. [7][8][9][10] La filtración con tintes y la filtración microbiana son los dos métodos más comunes para evaluar la microfiltración de obturaciones endodónti-cas, 11 pero la filtración microbiana es el método más relevante, ya que se ajusta a las condiciones clínicas.…”

“…Even in the text of results on p.159; left column, second paragraph, it was mentioned as “there were 53 cases (83.33%) with postoperative voids and 7 (11.67%) had no postoperative voids.”[1] This in actual should be in reverse.…”
