Question 1

Do you provide workshops?

Sendo Line · Accepted Answer

Yes, we arrange workshops on a regular basis in all markets where we are present. For information on dates, take a look at our web page Courses & Events or ask your local dealer.

Question 2

When can I use the S1 Plus Small 15/06 instrument?

Sendo Line · Accepted Answer

The instrument S1 Plus Small 15/06 is indicated for very small / narrow canals. In canals where the S1 Plus Standard 25/06 instrument can not easily proceed to working length, use the S1 Plus Small 15/06.

Question 3

How often do I need to lubricate the S1 contra-angle handpiece?

Sendo Line · Accepted Answer

We recommend that you clean, disinfect and lubricate the contra-angle in-between every patient. For more details, please consult the instructions for use.

Question 4

Can the S1 Plus instruments be re-sterilized if the expire date is passed?

Sendo Line · Accepted Answer

All S1 Plus instruments are pre-sterilized and ready to use. We recommend that you use them as single-use prior to expiration date.

Question 5

When I have cleaned the canal with the S1 Plus file, the Gutta percha point does not fit in the coronal part of the canal. Why is that?

Sendo Line · Accepted Answer

This situation can occur in a very long canal, where the files working part is passing the floor of the cavity. The best way to avoid this situation is to use a brushing motion with the file on the "way out" of the canal during preparation.

Question 6

Can I use other file systems with the S1 contra-angle handpiece?

Sendo Line · Accepted Answer

You can use the S1 Plus instruments and the S5 files in the S1 contra-angle handpiece.

Question 7

Do you supply matching gutta-percha points for S1 Plus Small 15/06?

Sendo Line · Accepted Answer

No, it will be very difficult to do the obturation already after a size 15/06. Our recommendation is to prepare the canal up to a size 25/06 (S1 Plus Standard instrument) before obturation.

Question 8

What motor should I use with the S1 contra-angle handpiece?

Sendo Line · Accepted Answer

Choose the S1-E contra-angle handpiece for an electric motor (maximum speed 40,000 RPM).

Choose the S1-A contra-angle handpiece for an air motor (maximum speed 25,000 RPM).

When using the appropriate S1 contra-angle handpiece for your motor, always give full speed when working with the S1 files.

Question 9

Are there bigger files than the S1 Plus file (25/06) available with the S1 system?

Sendo Line · Accepted Answer

Yes, for larger canals you use the S1 Plus Large 40/04 availible in length 25 mm and 31 mm.

Question 10

What if I can´t reach the working length with the S1 Plus Standard 25/06?

Sendo Line · Accepted Answer

Use the S1 Plus Small 15/06 in cases with very narrow canals if the S1 Plus Standard 25/06 instrument does not reach working length. After reaching working length with the S1 Plus Small 15/06, finish the preparation with the S1 Plus Standard 25/06 instrument.

Question 11

Do the S1 Plus files come in pre-sterilized blisters?

Sendo Line · Accepted Answer

Yes, the files are ready to use out of the package.

Question 12

Can I adjust the torque setting on the S1 contra-angle handpiece?

Sendo Line · Accepted Answer

No, and there is no need for it. The reciprocating movement enables safe progression of the S1 files without torque control.

Question 13

What about the cutting angle of the S1 Plus file?

Sendo Line · Accepted Answer

The S1 Plus file has an S-shaped cross section with a positive cutting angle.

Question 14

Are all S1 instruments sterile?

Sendo Line · Accepted Answer

Yes, all are sterile blister packed. Ready to use.

Question 15

Can I use the S1 Plus-files in another endo motor or contra-angle handpiece?

Sendo Line · Accepted Answer

No, we do not recommend use of the S1 Plus-files in other endo motors or contra-angle handpieces. The S1 contra-angle handpiece creates the correct movement for safe and efficient use with the S1 Plus-files.

Question 16

Can I attach my apex locator and use it with the S1 contra-angle?

Sendo Line · Accepted Answer

Yes, just connect the S1 Apex Clip to the S1 contra-angle handpiece and your apex locator to the apex clip.
