Primary Outcome Measures

Name	Time	Method
Periodontal probing pocket depths as assessed by an electronic periodontal probe (Florida probe) with automated force application for reproducibility[Assessed at baseline, 1 week after treatment, then at 1 month, 3 months and 6 months.];Bleeding on probing as assessed by the number of sites with spot bleeding within 15 seconds following periodontal probing [Assessed at baseline, 1 week after treatment, then at 1 month, 3 months and 6 months.]

Secondary Outcome Measures

Name	Time	Method
Bacterial counts prior to and post treatment in the two groups.<br>Assessed by using a paper point placed into the periodontal pocket for approximately 15 seconds and measured using real-time PCR[At baseline, immediately after treatment, at 1 week, 1 month, 3 months and 6 months]
