An interventional study of Simplified papilla preservation flap and Resective periodontal flap with osseous recontouring in Healing Wound and Periodontitis, sponsored by Queen Mary University of London. Completed at 1 site in United Kingdom. Open to participants aged 30 Years and older. Per ClinicalTrials.gov, last updated 2026-02-19.
Sponsored by Queen Mary University of London · Not applicable, Interventional, and Other
This is a single centre, randomised, single-blind, parallel-group clinical trial that aims at evaluating the use of imaging (2D and 3D) in obtaining geometric and thermometric changes of postoperative healing patterns and comorbidities (facial swelling, oedema and inflammation) following two routine surgical procedures performed for the treatment of periodontal (gum) disease.
A surgery in a posterior sextant will be performed per patient. The surgical procedures being compared for their post-operative healing patterns are:
Geometric (3D) surface imaging and thermal (2D) surface imaging will be used to assess the post-operative healing patterns and comorbidities (facial swelling, oedema and inflammation) following either of the surgical procedures.
1,635 studies on the registry are indexed under Periodontitis; 327 are open to participants now.
This study's enrollment of 60 is above the median of 45 across 1,191 interventional studies indexed under Periodontitis.

Exclusion Criteria:
PERIODONTAL SURGICAL INTERVENTION:The first arm is the simplified papilla preservation flap (SPPF) surgery.At visit 3, the SPPF surgery is performed. 2D and 3D imaging on surgical site will be carried out pre and post surgery. 2D and 3D imaging performed on surgical site for all post operative visits.
Procedure: Simplified papilla preservation flap
PERIODONTAL SURGICAL INTERVENTION: The second arm is the Resective periodontal flap with osseous recontouring (RPFO). At visit 3, the RPFO surgery is performed. 2D and 3D imaging on surgical site will be carried out pre and post surgery. 2D and 3D imaging performed on surgical site for all post operative visits.
Procedure: Resective periodontal flap with osseous recontouring
The simplified papilla preservation flap (SPPF) surgery is a conservative surgical procedure aimed at the preservation of the tissues between the teeth providing access for the debridement of the root surface in sites with residual pockets.
Also known as: SPPF
The Resective periodontal flap with osseous recontouring (RPFO) is a surgical procedure that achieves predictable pocket depth reduction by soft and hard tissue resection to obtain a more convenient soft and hard tissue architecture for oral hygiene.
Also known as: RPFO
Geometrical (3D) imaging in post-periodontal surgery wound healing.
Subtracted images from the baseline will identify the area and magnitude of the swelling (changes in volume) in the area of surgery (extra and intra orally).
Time frame: Period from pre-surgery to 90 days post-surgery
Thermal (2D) imaging in post-periodontal surgery wound healing.
Subtracted thermography images from the baseline will identify the change of the tissue temperature in the area of surgery (extra and intra orally).
Time frame: Period from pre-surgery to 90 days post-surgery
Patient related outcome measures (PROMs) particularly on oral health related quality of life
The secondary objective of this study is to evaluate the impact of the two surgical procedures on patient related outcome measures (PROMs). The Oral impact on daily performances index (OIDP) is going to be used to evaluate health and treatment outcomes.
Time frame: Period from pre-surgery to 90 days post-surgery
