The CLEARFIL MAJESTY ES Flow composite syringe and plunger features a special design that limits the possibility of the dripping and backflow of the material during or after dispensing. (Image: Kuraray Noritake Dental)

The O-ring construction prevents the material from flowing after pressure is released and ensures minimal retraction. (Image: Kuraray Noritake Dental)

Retracting the plunger after administering the composite may cause air to enter the syringe. (Image: Kuraray Noritake Dental)

When using a silicone index in the flowable injection technique, the appearance of air bubbles can be avoided by ensuring that the index fits tightly to the tooth and is not moved during injection. (Image: Kuraray Noritake Dental)

If the injection hole is too small, the index may be moved by the application tip during insertion or application, resulting in air bubbles in the restoration. (Image: Kuraray Noritake Dental)
