Abstract:

OBJECTIVE: To compare the apical sealing ability of injectable thermoplasticized gutta percha 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 April 2016. 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 thermoplasticized gutta percha and group II solid core using Thermafil. All samples were kept in methylene dye blue for 3 weeks and all were sliced horizontally in three levels and dye 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 and there were five (16.66%) samples showed presence of dye in Group II. The study found insignificant difference between Obtura-III and Thermafil 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 were 0.026 ± 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 indicates insignificant difference of dye penetration between two groups. CONCLUSION: The study showed insignificant difference of apical sealing ability between two obturation techniques.
