研究概览
简要总结
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.
详细描述
A surgery in a posterior sextant will be performed per patient. The surgical procedures being compared for their post-operative healing patterns are:
- Simplified Papilla Preservation Flap (SPPF) which is a conservative flap aiming at preserving the tissues between teeth.
- Resective Periodontal Flap with Osseous Recontouring (RPFO) which is a conventional surgery which involves hard and soft tissues resection.
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.

盲法说明
The calibrated examiners will be blinded to the study treatment. Samples will be labelled anonymously with subject ID and without codes relating to treatment group; therefore, all sample analyses will be blinded.
Blinding of the statistician will also take place. Data will be coded during data entry according to treatment group with a number disallowing group identification during analyses. Code details of which each treatment group will be revealed only once analyses are complete.

- •Antibiotic, anti-inflammatory or anticoagulant therapy during the month preceding the baseline exam.
- •History of alcohol or drug abuse.

研究组 & 干预措施
Simplified papilla preservation flap
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.
干预措施: Simplified papilla preservation flap (Procedure)
Resective flap with osseous recontouring
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.
干预措施: Resective periodontal flap with osseous recontouring (Procedure)
结局指标
主要结局
Thermal (2D) imaging in post-periodontal surgery wound healing.
时间窗: Period from pre-surgery to 90 days post-surgery
Subtracted thermography images from the baseline will identify the change of the tissue temperature in the area of surgery (extra and intra orally).
Geometrical (3D) imaging in post-periodontal surgery wound healing.
时间窗: Period from pre-surgery to 90 days post-surgery
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).
次要结局
- Patient related outcome measures (PROMs) particularly on oral health related quality of life(Period from pre-surgery to 90 days post-surgery)
