Lay Summary
|
The aim of this study is to compare the effectiveness and cost-effectiveness of theoretically based, personalised oral hygiene advice (OHA) or periodontal instrumentation (PI) at different time intervals (no PI; 6 monthly PI or 12 monthly PI) or their combination to routine OHA, for improving periodontal health in dentate adults attending general dental practice.

Who can enter the trial
|
1. Adult patients, either sex (more than or equal to 18 years of age) with periodontal health, gingivitis or moderate periodontitis (BPE 0-3) who:
1.1. Are dentate
1.2. Have attended for a check-up at least twice in the previous 2 years
1.3. Receive their dental care in part or fully as an NHS patient
|
|
Who cannot enter the trial
|
1. Patients with periodontal disease with a Basic Periodontal Examination (BPE) score of 4 (probing depth > 6mm and/or furcation involvements or attachment loss of 7mm or more) in any sextant on the basis more extensive periodontal care is indicated
2. Patients with an uncontrolled chronic medical condition (e.g. diabetes, immunocompromised)
|
|
What will happen
|
1. Dental practices will be randomised (cluster randomisation) to personalised oral hygiene advice (OHA) which will be tailored to the needs of the patient or routine OHA.
2. Subsequently participants will be randomised to one of three groups:
2.1. No periodontal instrumentation (PI)
2.2. 6 monthly PI
2.3. 12 monthly PI
3. Participants will be followed up annually by postal questionnaire for 3 years

|
Primary aim
|
1. Clinical: Gingival inflammation/bleeding on probing at the gingival margin measured using the Gingival Index of Loe by a trained blinded outcome assessor at baseline and 3 years follow-up
2. Patient centred: Oral hygiene self-efficacy collected annually by questionnaire
3. Economic: Net benefits (mean willingness to pay minus mean costs)
|
|
Secondary Aim
|
1. Clinical: Calculus to the Ramfjord Calculus Index and periodontal pocket depth using the colour-coded UNC periodontal probe measured by a trained blinded outcome assessor at baseline and 3 years follow-up; additional periodontal instrumentation and referral
2. Patient centred: dental quality of life, oral health behaviour, knowledge, cosmesis collected annually by questionnaire
3. Economic: Costs to the National Health Service (NHS) and patients, willingness to pay
4. Providers: Beliefs relating to giving oral hygiene advice and maintenance of periodontal health collected by questionnaire at baseline and 3 years follow-up
