RESUMO
Background: Self Adjusting Files have been introduced to overcome the disadvantage of protaper rotary files, especially for oval root canal centering. Aims and Objectives: To evaluate the canal centering ability between rotary protaper and self adjusting file in oval shaped canals using cone beam computed tomography. Methods:The study was carried out on 20 single rooted mandibular premolars. To compare the canal centering ability produced by different techniques, pre-instrumentation, post-instrumentation, cross section images of specimen at 3, 6 and 9 mm from the apex were obtained from the 3D CBCT images of each individual group. The images captured digitally using Image Tools Software were compared. Results: Inter group comparison of mean ratio of both the groups at 3, 6 and 9 mm after preparation of canal showed statistically significant difference between both the groups (p<0.05). Intra group comparison of mean ratio of both the groups at 3, 6 and 9 mm after preparation of canal showed that the difference between both the groups was not statistically significant (p>0.05).Conclusion: The canal centering ability of self adjusting file was efficient than protaper rotary files.
RESUMO
In the recent years the practice of oral implantology has been expanding widely and is creating an area of interest for the dental practitioners and awareness among the patients. Though the use of prophylactic antibiotics during implant placement still remains controversial, several clinical studies suggest that the use of prophylactic antibiotics significantly improves short and long term implant survival. Also prior to oral surgical procedures patients with risk for developing infectious endocarditis and immuno compromised antibiotic prophylaxis is well recommended.
