چکیده

INTRODUCTION Success of non-surgical root canal treatment is predicted by meticulous cleaning and shaping of the root canal system, three-dimensional obturation and a well-fitting "leakage-free" coronal restoration. The techniques of obturation that are available have their own relative position in the historical development of filling techniques. Over the years, pitfalls with one technique have often led to the development of newer methods of obturation, along with the recognition that no one method of obturation may satisfy all clinical cases. MATERIALS AND METHODS A total of 120 extracted human permanent anterior maxillary and mandibular single rooted teeth were selected for the present study and divided into 3 groups based on the method of obturation technique. Following the preparation the patency at the apical foramen was confirmed by passing a file #15. After obturation of all three groups, teeth were immersed in 1% of aqueous methylene blue dye for a period of two weeks and then samples were subjected to spectrophotometric analysis. RESULTS The present study was conducted to evaluate in vitro the spectrophotometric analysis to quantitatively analyze relative amount of dye penetration using lateral condensation (Group I), Obtura II (Group II ), Thermafil obturating technique (Group III) with ZOE sealer used in all groups. Teeth obturated with lateral condensation (Group I) shows mean value of 0.0243 and standard deviation of 0.0056. The Group II thermoplasticized injectable moulded Guttapercha (Obtura II) showed 0.0239 mean and standard deviation value of 0.0045 and Group III Thermafil obturation technique shows 0.0189 as mean value and 0.0035 standard deviation values. CONCLUSION Following conclusion was drawn from the present study. Group III i.e., Thermafil obturating technique shows minimum mean apical dye penetration compared to Group II (ObturaII) and Group I (lateral condensation).Lateral condensation shows maximum mean apical dye penetration in all three groups.There is no significant difference between the apical dye penetration of lateral condensation and Obtura II.

Comparison of Bacterial Leakage between 3 Different Root Canal Obturation Techniques in Oval Shaped Canals

Introduction: The purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. Methods: Sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. The teeth were sectioned at a 10 mm distance from the apex. After instrumentation, the teeth were divided into 3 gr...

Negative influence of continuous wave technique on apical sealing of the root canal system with Resilon.

The aim of this study was to investigate apical microleakage after use of the Resilon system in comparison with gutta-percha. The materials used were 54 mesial roots of mandibular molars with an apical curvature of 20-40 degrees . The root canals were instrumented with the Prosystem GT(R) and obturated with: Group I: Gutta-percha + Sealer by lateral condensation (n = 25); Group II: Gutta-percha...
