Preoperative radiographic analysis

Here is a case of endodontic treatment to Necrotic tooth number 26 where from clinical evaluation and assessment, canal space could be cleary noticed along being short in length with no severe curvatures.

So a decision to mange this case using only rotary files was taken.

F1 essential kit rotary file system was selected to get the advantage of minimal contact of the file with canal walls and better debridement, thanks to the flat side design with large chip space.

Fig. 2

All canals preflared and coronally enlarged to 25 - 06 followed by 20 - 04, 25 - 06, 35 - 04 in MB,D and palatal canals as they were large and wide canals.

For MB2 

Coronal preflaring done using 25 - 06 to decrease stresses on apically working files,  followed by 20 - 04, 25 - 06 to full length.

Conclusions

Preoperative radiograph is very important before starting endodontic treatment and it could help in decision making specially for technique selection.

Clinician experience has a great influence on shortening shaping time through skipping what could be unnecessary steps during treatment giving more time to chemical disinfection.

Essential kit files with flat design from Fanta show good performance during shaping of regular and easy wide canals without manual glide path files.
