Secondary Outcome Measures:
  • attachmentlevel loss

Estimated Enrollment: 60
Study Start Date: April 2004
Estimated Study Completion Date: January 2005
Detailed Description:

The purpose of the study is to evaluate the effect of the photodynamic therapy in periodontal pockets and to assess the reduction of subgingival bacteria.

The first step will include the evaluation of the quantity of the light which will activate the photosensitizer in the various niches in the periodontal pocket.

The second step will evaluate the distribution of the photosensitizer in the periodontal pocket.

The third step will assess the woundhealing of the the photodynamic therapy compared to conventional periodontal therapy with an ultrasonic device.
