All

Inclusion criteria

Inclusion criteria: 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

Exclusion criteria

Exclusion criteria: 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)

Design outcomes

Primary

Measure	Time frame
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

Measure	Time frame
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	—
