Destruction of bacterials, periimplantitis, infections, root channel infections – Photo Dynamic Therapy
|Inndication||Destruction of bacterials|
|Additional||Apply Tolonium chloride and irradiate the cavity/root channel directly with the laser using a special dental applicator, fiber optic.|
For disinfection, the laser is used in combination with special drugs, for the so called Photo Dynamic Therapy (PDT) or in this case Photo Dynamic Disinfection (PDD).
The PDT became available for use in both caries and infections of the soft tissue, endodontics.
Principle of function:
Laboratory studies have shown that an important aspect of this system is that the two components when used independently of one another produce no effect on bacteria or on normal tissue. It is only the combination of photosensitiser and light which produces the effect on the bacteria.
How to perform the PDT/PDD
The PDT is fast, secure and easy to perform:
Aftercare: Place a non-setting calcium hydroxide paste (e.g. UltraCal) into the canal, cotton wool pledget (Roeko, Germany) in the pulp chamber and dress the tooth with IRM (Dentsply, DeTrey) in the case of posterior teeth or Chemfil Superior (Dentsply, DeTrey) in the case of anterior teeth.
This PDT system has been evaluated in the laboratory and destruction rate of bacterial is in the order of 109, achieved under conditions comparable to those found clinically
The following bacterials can be destroyed:
