Bottom Line: Group 1and 2, each with 30 teeth, were obturated in the room and intracanal temperature respectively.Data was analyzed with student-t test and also Kolmogorov- Smirnov Goodness- of- Fit test to make sure of data.Under the condition of this invitro study, apical sealing ability was better in the body-simulated temperature than the room temperature, although it was not statistically significant.

ABSTRACT

Statement of problem: Studies reported that nearly 60% of endodontic failures have been attributed to inadequate obturation of the root canal system. Thus, complete obturation of the root canal system and proper apical seal are essential elements in the long-term success of root canal treatment.

Purpose: This study aimed to compare the apical seal of lateral condensation technique in the room and in body- simulated temperature.

Materials and method: In this experimental study, 70 extracted, single- rooted, human premolar teeth were instrumented and divided up into four groups. All tooth's canals were obturated by lateral condensation technique except the teeth in the positive control group. Group 1and 2, each with 30 teeth, were obturated in the room and intracanal temperature respectively. The other two groups were positive and negative control group each with 5 teeth. All groups except negative control were covered by two layers of nail polish. Then linear dye penetration was evaluated with a stereomicroscope. Data was analyzed with student-t test and also Kolmogorov- Smirnov Goodness- of- Fit test to make sure of data.

Results: RESULTS showed that dye penetration in group one (obturation in room temperature) was 0.6mm more than group 2 (obturation in simulated-body temperature) although this was not statistically significant (p> 0.05).

Conclusion: Under the condition of this invitro study, apical sealing ability was better in the body-simulated temperature than the room temperature, although it was not statistically significant.

Mentions: The negative control group demonstrated no dye penetration while the positive control showed dye penetration along the entire root length. The mean linear dye leakages for the two groups are shown in Table 1, and Figures 2a and b.
