Oral and dental hygiene advice


This information is provided directly by researchers and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information.


It is well known that dental plaque is the main cause of gum disease. Effective oral hygiene (tooth brushing and inter-dental aids) for plaque control and the removal of calculus (tartar) by your dentist or hygienist with a scale and polish are considered necessary to prevent and treat gum disease. However, there is a lack of strong evidence to inform dentists about what type of oral hygiene advice is most beneficial for their patients. There is also a lack of strong evidence to inform dentists about the most effective time interval for providing a scale and polish. The purpose of this study is to investigate and compare the effectiveness and cost- effectiveness of providing personalised oral hygiene advice and/or scale and polish at different time intervals for improving gum health in adults attending general dental practice. The results of this study will provide much-needed evidence on the best type of oral hygiene advice for patients and the most appropriate time interval between scale and polishes in order to prevent and treat gum disease .

A study hygienist will examine your teeth and gums to record information about the health of your gums . If this examination reveals gum disease that requires specialist care you will be informed and will not be allocated to a study group. However, we will ask for your permission to follow you up over the three years in the same way as the other study participants. In order to compare routine and personalised oral hygiene advice, your dentist/hygienist has been asked to provide all their patients with either advice as usual (routine) or to base the advice on health status and to demonstrate using appropriate toothbrushes and inter-dental aids (personalised). Depending on which type of advice your dentist/hygienist has been asked to provide you will receive routine or personalised oral hygiene advice at the first visit and as required at any subsequent visit for a check up or treatment. At this first visit your dentist/hygienist will also provide you with a thorough scale and polish to remove all plaque and deposits of calculus. In order to compare routine and personalised oral hygiene advice and scale and polish at different time intervals, you will be randomly (i.e. by chance) allocated to one of three different time intervals for a scale and polish: six monthly scale and polish; yearly scale and polish; or no scale and polish. The group you are allocated to will be selected by a computer. All participants will receive a £25 gift voucher in recognition of your contribution to the study. Your involvement in the study will be for a period of three years.
At the first visit you will also be asked to complete a confidential questionnaire asking about your views of the service you get from your dental practice, and your attitudes and beliefs towards oral health. You will be asked to complete this questionnaire again at 1 year, 2 years and 3 years after your first visit. It is estimated that each questionnaire will take about 30 minutes to complete. In total you will be asked to complete four questionnaires during the study. Three years after your first check-up appointment you will be asked to attend for a dental examination. This examination will take place in your dental practice. However, the examination will not be carried out by your dentist, but will be carried out by an independent dentist/hygienist who is employed by the study. The study will also compare the number and types of treatments received by patients.


We are asking patients who have attended their dentist at least twice during the previous two years to take part.

You can take part if:



You may not be able to take part if:


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 indicated2. Patients with an uncontrolled chronic medical condition (e.g. diabetes, immunocompromised)

During the study you will not be asked to see your dentist less frequently. No matter which group you are allocated to if at any time there is a need to provide care for your gums more often, including referral to a specialist, this will be arranged and the treatment recorded. It is possible that you may be allocated to a group where you receive care more often than usual and , if so , your oral health will be monitored more often than usual. Of course you are free to attend your dentist at any time if you develop any dental problems (e.g. toothache) in between check-ups.
