Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   38975   clinical trials with a EudraCT protocol, of which   6398   are clinical trials conducted with subjects less than 18 years old.
    The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To compare the effect of prescribing 5000ppm fluoride toothpaste with usual care on treatment for caries, including coronal/root restorations, endodontics or extractions

    To compare the costs and benefits, within a net benefit framework of prescribing 5000ppm fluoride toothpaste with usual care
    E.2.2Secondary objectives of the trial
    Secondary objectives will evaluate the effect of prescribing 5000ppm fluoride toothpaste on caries (mean Decayed Missing Filled Surfaces [DMFS]) increment, progression of early caries lesions, bleeding on probing, quality of life (generic and condition specific), costs to the NHS and to individuals and society, oral health behaviour and episodes of pain. In addition, we will explore the attitudes of clinicians and patients to the prescribing and use of high fluoride toothpaste.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    A more detailed clinical examination undertaken by independent (external to the trial dental practices) dentists will be used to repeat primary outcome measures and collect secondary outcomes (caries increment and bleeding on probing). This more detailed clinical examination will take place in Scottish practices only and the independent examiners will be blind to the allocation. All clinical outcomes will be assessed at baseline and three years by trained examiners. Training will be provided by an expert in caries assessment and the use of criteria in caries clinical trials.

    A detailed caries measurement will be made using the validated International Caries Detection and Assessment System (ICDAS) for coronal caries. The ICDAS criteria measure both early and more advanced stages of caries. For early caries, ICDAS measures the surface changes and potential histological depth of carious lesions by relying on surface characteristics related to the optical properties of sound and demineralised enamel prior to cavitation. The primary requirement for applying the ICDAS system is the examination of clean and dry teeth aided by a ball-ended explorer that is used to remove any remaining plaque and debris and to check for surface contour, minor cavitation or sealants. All surfaces of all teeth will be examined and the caries status recorded.

    Periodontal Gingival inflammation as bleeding will be measured according to the Gingival Index of Loe by running a UNC periodontal probe circumferentially around each tooth just within the gingival sulcus or pocket. After 30 seconds, bleeding will be recorded as being present or absent on the buccal and lingual surfaces.
    E.3Principal inclusion criteria
    • aged 50 years or older
    • with a diagnosis of active coronal caries (into dentine) in the last 12 months which may\may not have been treated, or any root caries; and\or other risk factors as determined by their GDP.
    • receive their dental care in part or fully as an NHS patient
    • living in any residential setting, and
    • for whom their GDP decides prescription of high concentration fluoride toothpaste is appropriate for the patient
    E.4Principal exclusion criteria
    • are currently prescribed (by General Dental Practice or General Practitioner) high concentration fluoride toothpaste (for GDPs prescription must have been issued at last examination visit)
    • hypersensitivity for Sodium Fluoride and\or other ingredients used in 5000ppm toothpaste
    • are living in the same household as someone already recruited to Reflect
    • are unable to provide informed consent
    E.5 End points
    E.5.1Primary end point(s)
    The proportion of participants receiving any dental treatment due to caries; including restorations, endodontics or extraction.
    E.5.1.1Timepoint(s) of evaluation of this end point
    At 12, 24 and 36 months after commencing treatment
    E.5.2Secondary end point(s)
    Secondary outcomes (patient reported):

    • Oral health status using OHIP14, a measure of oral health-related Quality of Life (QoL), collected at baseline and annual follow up through patient administered questionnaires. The OHIP-14 is the most common, validated dental quality of life instrument and has been successfully used in previous HTA trials. It has been found to be sensitive to differences in oral health and is closely correlated with self-reported oral health outcomes.

    • The EQ-5D-5L profile measure of generic health status will be collected at baseline and annual follow up through patient questionnaires.

    • Any episode of dental pain (and total number per participant) during the 3 year follow up period severe enough to trigger an unscheduled visit to a healthcare profession (dentist, GP, community pharmacist). This will be recorded at scheduled and unscheduled dental visits by patient questionnaire.

    • Oral health behaviour, including self-reported brushing/other sources of fluoride. Evaluated at baseline and through annual questionnaires sent by mail to the home address of participants.

    Secondary outcomes (clinically assessed): The clinically assessed secondary outcomes will be measured in Scottish practices only. Clinically assessed secondary outcomes are:
    • Coronal caries increment, including dentist replacement restorations for caries, at tooth surface (DMFS) level by independent, trained and calibrated, clinical examiners at baseline and 3 year (+/- 3 months) follow-up. We will use the ICDAS method to assess caries as it provides flexibility to analyse and present caries data at different diagnostic thresholds.
    • Root caries increment, including dentist replacement restorations for caries, at tooth surface (DMFRS) level by independent, trained and calibrated, clinical examiners at baseline and 3 year (+/- 3 months) follow-up.
    • Early caries lesion progression data, using ICDAS.
    • Bleeding on probing (BoP) will also be recorded by the independent clinical examiners. BoP provides evidence of long term optimal brushing rather than transitory measures such as visible plaque scores.
