This investigation aims to describe the early healing events (up to 4 weeks) in terms of 3D/2D volumetric and thermal changes, expression of gingival crevicular fluid (GCF) markers, as well as PROMs associated with the regeneration of periodontal intrabony defects performed with guided tissue regeneration (GTR) or plasma rich in growth factors (PRGF), both combined with a simplified papilla preservation flap (SPPF).
While this study will assess several additional outcomes as part of a large randomized, single-blind, parallel-group controlled trial (like changes in PPD (primary outcome) and other clinical and radiographic parameters), this PhD thesis will specifically focus on the application of non-invasive 3D/2D imaging technologies to describe the different intra-oral/extra-oral healing patterns during periodontal regeneration, on the expression of specific GCF markers and on the characterization of PROMs. More specifically, for this PhD project we will consider the following outcomes:
Primary outcome: Post-operative swelling, oedema and change in temperature at different early healing time points (2, 7, 14, 30 days after surgical treatment) assessed with the help of 3D intra and extraoral geometrical and extra-oral 2D Thermal imaging
Secondary outcomes: - Changes in patients’ reported outcomes (PROMs) measured with Global ratings of Periodontal Health and Quality of Life, global changes in quality of life, EuroQol-5D-5L and patient perception about therapy up to 1 month post-surgical treatment; - visual assessment of gingival healing and early healing index up to 2 weeks post-surgical treatment; - changes in GCF markers of inflammation, angiogenesis and bone formation at different early healing time points (2, 7, 14, 30 days after surgical treatment)
The study has already received funding from Osteology Foundation (PI: N. Donos) and has already received ethics approval. Registration in clinicaltrials.gov has also been obtained. Patient recruitment started (10 patients out of 74 originally planned have been recruited) and visits are ongoing.
The Trustees of The Medical College of Saint Bartholomew’s Hospital Trust (MCSBHT) have offered funding for a research studentship, for a clinically qualified candidate to commence in October 2023, leading to a PhD degree from The QMUL Faculty of Medicine and Dentistry.
This studentship will fund a student with a clinical qualification and GMC / GDC registration at any career stage below consultant. The Studentship will cover the successful candidate’s current clinical salary and will include PhD fees (at home fee rate) with up to £6000 pa for consumables. Further consumables / funding for travel may be available on application.
