  • Research summary

    Dental and gum diseases are still very common in the UK and the damage caused by tooth extraction or gum disease is a matter of interest. Rebuilding gum and bone tissues after tooth removal is a critical point when planning to replace the tooth with either a bridge or dental implant. Our aim in this study to assess whether small grafts of gum tissues taken from a patient could be used to improve the gum and bone rebuilding after removing a tooth and prior to placing a dental implant.

    In this study we wish to identify 44 participants who need a tooth removal (due to fracture or infection) and will need some bone gum and bone rebuilding. They will be allocated at random to either filling the tooth socket with a collagen plug only (control/standard of care) or a collagen plug with small gum grafts. A subset of participants (group A) will receive their dental implant after 6 weeks from the tooth removal whilst the rest (group B) will receive their dental implant at 12 weeks. This way we will be able to assess the bone healing at two different stages.
    A series of clinical assessments (during and after removing the tooth) will be made alongside with a three-dimensional scan (CT scan), and non-invasive imaging (Optical Coherence Tomography, laser doppler and Ultrasound). Lastly the patients’ experience before and after the procedure with regards to discomfort and impact on their daily life will be recorded in all participants using validated questionnaires (Oral Impact on Daily Performance and Health Questionnaire EQ-5D-5L).
