Đánh giá kết quả điều trị răng hàm lớn thứ nhất, thứ hai hàm trên bằng kĩ thuật hàn Thermafil có sử dụng phim Cone Beam Computed Tomography

Abstract

Objective: To evaluate the outcome of root canal treatment maxillary first and second molars using Thermafil as filling technique, using Cone Beam Computed Tomography. Subject and method: A prospective clinical trial involving 55 teeth in 50 patients, which required root canal treatment and finally filling with Thermafil technique. The time used for the root canal filling, the quality of root canal treatment was recorded. The treated teeth were examined both clinically and radiographically 6 months, 1 year, 2 years after the treatment. Result: 92.7% of the teeth had good obturated length. Teeth had good obturated density at: 100% in apical 1/3rd, 98.1% in coronal and middle of canal. The average obturated time was 5.25 minutes with maxillary first molars, 4.22 minutes with maxillary second molars. The healing rate after 6 months, 1 year, 2 years were 85.5%, 87.3% and 89.1%, respectively. Conclusion: This study shows the efficiency of Thermafil obturation systems in 3D filling root canals hermetically. Results show the good sealing ability of Thermafil technique making its appropriate to use in daily endodontic obturations.
