FotoSan – a new antibacterial treatment without medication

Light Activated Disinfection (LAD)

The LAD concept has an exceptionally promising future in dentistry as it is particularly useful in the destruction of bacteria embedded in biofilm, works instantly and does not create antimicrobial resistance. The treatment is fast and easy to apply and is without any side effects at all.

Treatment indications

• Endodontics
• Periodontitis
• Periimplantitis
• Pericoronitis
• Gingivitis 
• Caries

The concept

LAD, also called PACT (Photodynamic Antimicrobial Chemo Therapy) is a treatment based on the combination of a photosensitizer and a powerful red light.
The photosensitizer attaches to the membranes of microorganisms,  absorbs energy from the light and then releases this energy to oxygen, which is transformed into highly reactive oxygen species (ROS), such as oxygen ions and radicals. The ROS destroy the microorganisms instantly and effectively.

Endodontic treatment

The root canal is instrumented and flushed.The canal is filled with photosensitizer. Each canal is illuminated for 30 seconds with the endodontic tip attached. Rinse, dry and and follow your usual filling procedure.

Periodontic treatment

Scaling and root planning is performed.
The photosensitizer is applied into pockets. Deep pockets are illuminated for 10 seconds with a long tip in the pocket and then from the outside for 10 seconds with a blunt tip pushed firmly against the mucus membrane.

Periimplantitis

Is treated in the same way as periodontitis.

Gingivitis and pericoronitis

The photosensitizer is applied in the gingival pocket and is treated for 10 seconds with a blunt tip pushed firmly against the mucus membrane.

Treating caries

Especially for decontaminating profound caries. After excavating the majority of the carious dentine, the photosensitizer is
applied and is illuminated for 10 seconds. It is then sealed with a temporary filling.

The LAD principle is not only effective against bacteria, but also other micro organisms like viruses, fungus and protozoa.

The applied photosensitizers have far less affinity to mammal cells; and thus no negative side effects in the treatment have been noted.

As a result, light activated disinfection (LAD) has a number of advantages in relation to both traditional antibiotic treatment and chemical disinfectan.
