Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A trained periodontist and a periodontics registrar will undertake the procedures and examination. Both have a Bachelor of Dental Surgery and one holds a Masters in Periodontics.

Baseline 2 x 60mins
Pre-study treatment will occur over 2 appointments and involves the consent procedure as well as alginate impressions and radiography (panoramic or periapical as suitable for the patient)

Periodontal treatment will occur over 2 sessions for each patient at the following next available times (2x 60 mins)
Use of "air polishing", compressed air with erythritol powder, in combination with ultrasonic and hand instrumentation (EMS ultrasonic scaler, Hu-Friedy Gracey and Universal Currettes) in the initial treatment and supportive treatment of periodontitis

Recall will occur at 3 months (1x60mins) where supportive periodontal therapy will occur and clinical and microbiological measurements

No adherence measurements will be undertaken, though a record of treatment is always kept for assessment.

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)
not applicable as this is a split mouth design - all patients receive both treatment on one side of the mouth and control treatment on the other side of the mouth
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
coin toss
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?


The people assessing the outcomes
The people analysing the results/data
Intervention assignment
Parallel
Other design features
Phase
Type of endpoint/s
Statistical methods / analysis
Participants are selected based on having similar affected sites in opposite sides of the mouth and thereby receive both treatments, one on each side, in a split-mouth study
