An Open Randomized Controlled Clinical Trial to Examine the Efficacy of Three Coronal Advancement Methods and L-PRF for the Treatment of Multiple Recession Defects: Patient-Reported Outcome Measure
The aim of this prospective randomized controlled clinical trial was to evaluate the patient reported outcomes (PROMs) and attempt to compare post operative pain of 4 modalities for coronal advancement of gingival margins to achieve root coverage; namely, Coronally Advanced Flap (CAF), Intrasulcular tunneling (IST), Vestibular Incision Subperiosteal Tunnel Access (VISTA) and VISTA+Leukocyte-Platelet Rich Fibrin (L-PRF).
materials and method
Participants with Miller class I, II or III recession defects were randomly allocated to 4 intervention groups: CAF, IST, VISTA or VISTA+L-PRF. Three days after the surgical intervention a visual analogue scale (VAS) in addition questionnaires were given to the participants to assess PROMs of the interventions. Moreover, analgesic used was determined by counting the number of analgesic tablets used.
The initial PROM and analgesic usage data are shown below. As there is continuous recruitment, updated data will be presented at a later date.
The PROMs after therapeutic intervention is a crucial element of recognizing patient experience. Gaining insights about patient experiences can help adopt therapeutic interventions which are best accepted by patients.
Initial Data shows that the group being treated with VISTA + L-PRF seem to have the least amount of post operative pain according to VAS, this was followed by IST then CAF. Further recruitment is needed to support these finding and evaluate PROMs of VISTA in relation to these results.
