ABSTRACT

OBJECTIVE: To compare the apical sealing ability of injectable thermoplasticizedguttapercha and solid core obturation technique.

STUDY DESIGN: In vitro comparative study

Place and Duration: At Department of Operative Dentistry Isra Dental College and Mehran University from 8th October 2015 to 8th April2016.

METHODOLOGY: Sixty samples of extracted permanent teeth were selected and divided into two groups. Endodontic access opening,working length and preparation were performed. Then group I obturated with injectable thermoplasticizedguttapercha and group IIsolid core using Thermafil. All samples were kept in methylene dye blue for 3 weeks and all were sliced horizontally in three levels anddye presence and penetration was checked under stereomicroscope.

RESULTS: The results showed no dye presence at Level-2 and 3.At Level-1, six (20%) samples showed presence of dye in Group I andthere were five (16.66%) samples showed presence of dye in Group II. The study found insignificant difference between Obtura-III andThermafil with p-value 0.741 (p>0.05). The mean and standard deviation of dye penetration at level I in Group I and Group II were0.026 ± 0.069 and 0.020 ± 0.048. The mean difference was 0.006±0.868 with p-value 0.677(p>0.05) and 95% CI which indicatesinsignificant difference of dye penetration between two groups.

CONCLUSION: The study showed insignificant difference of apical sealing ability between two obturation techniques.
