Dentinal Adaptation of Warm Thermoplastic Obturating Material and Cold Thermoplastic Obturating Material: An Study.

INTRODUCTION

The objective of endodontic obturation is to provide a complete seal along the length of the root canal system, thereby ensuring the healing and sustained health of the periradicular tissue. Root canal obturation involves the three-dimensional filling of the entire root canal system and is a critical step in endodontic therapy. Gutta-percha has universally been accepted as the gold standard for root canal filling materials. However, it lacks bonding to the internal tooth structure resulting in the absence of complete seal.

AIM

The aim of the present study is to compare the dentinal adaptation of warm thermoplastic obturating material and cold thermoplastic obturating materials.

MATERIALS AND METHODS

Thirty single-rooted, anterior noncarious human teeth extracted for periodontal or orthodontic reasons were used for the study. The samples were stored in distilled water until obturation. The specimens were then randomly divided into three groups of ten specimens each: Control group - Cold lateral condensation with AH Plus, Group I - Endosure with AH Plus, and Group II - GuttaFlow 2 with master cone. The obturation for each group was done following manufacturer's instructions. Under On-demand software, the area of voids at the level of 3 mm, 5 mm, and 8 mm from the apex was observed for all the samples. The obtained results were submitted for statistical analysis.

RESULTS

The result in the present study showed that Endosure provides a better consistent seal as compared to cold lateral condensation, or GuttaFlow 2 techniques.

CONCLUSION

Mean void value was maximum for GuttaFlow 2 group, followed by cold lateral condensation, Endosure. Though there was a difference in the mean void values, it was not statistically significant except between Endosure and GuttaFlow 2. The result in the present study showed that Endosure provides a better seal as compared to cold lateral compaction, GuttaFlow 2 or Endosure technique.
