Dentist will be delivering the treatment (nonsurgical instrumention of teeth) which is the conventional form o therapy for chronic periodontitis
study will be conducted in 7 sessions, ( treatment will be in 2 sessions) over 6 months followup at the Oral health centre of WA
Arm 1: One Stage Full Mouth Disinfection protocol (Nonsurgical periodontal scaling and root planing+ use of mouthwash) + placebo x 3 days orally
Arm2; One Stage Full Mouth Disinfection protocol(Non Surgical periodontal scaling and root planing + use of mouthwashes ) +systemic antimicrobial (Azithromycin, 5oomg x 3 days orally)
Treatment session 1) Clinical charting ( microbiological , saliva sampling using paper points) completed by Specialist periodontist at least 5 years ( 90 min session )
2) Oral hygiene instructions and plaque score ( 30 minutes session ) completed by experienced hygienist ( 5years)

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
allocation involved contacting the holder of the allocation schedule who was "off-site" or at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data
Intervention assignment
Parallel
Other design features
Phase
Phase 4
Type of endpoint/s
Efficacy
Statistical methods / analysis
Data analysis will be carried out according to a pre-established analysis plan. The procedure will be performed by the principal investigator (postgraduate student) under the supervision of a biostatistician with expertise in dentistry and blinded to the group allocation. A comparison of the baseline PPD (probing depth) values between the two groups at baseline, and 3months after therapy will be presented as primary outcome
