简要总结
This is a pivotal, prospective, randomized, blinded, multicenter study to evaluate two treatments of photodynamic disinfection in adults with chronic periodontal disease. The study is expected to enroll a total of up to 105 subjects.
详细描述
The key question is whether scaling and root planing (SRP) followed by one or two doses of photodynamic disinfection using 0.01% MB result in improved outcomes that persist over time in adults with chronic periodontitis when compared with subjects with SRP alone. This study is meant to be pivotal in nature in the evaluation of photodynamic disinfection.
Primary Endpoint
The primary outcome of interest in this study is improvement in or stabilization of clinical attachment level. The clinical attachment level is the distance in mm from the cemento-enamel junction to the base of the sulcus or periodontal pocket as measured with a periodontal probe. In order to prevent study bias all endpoint measurements will be performed by a single examiner throughout the course of the study. A clinically significant difference will be considered as:
1) A measurement difference of 0.4 mm between treatment groups
