Clinical Trial Summary

Periodontitis is defined as loss of periodontal attachment due to microbial associated host mediated inflammation. This would lead to the apical migration of the junctional epithelium allowing the bacterial biofilm to undergo apical widespread along the root surfaces of teeth causing bone resorption (Tonetti, Greenwell, & Kornman, 2018). The main objective of periodontal surgeries is directed at complete preservation of the interdental soft tissues to achieve primary closure over the intraosseous defected sites during the early phases of wound healing. Evidence shows that surgical techniques are highly predictable in the treatment of pockets associated with deep and shallow intrabony defects affected majorly by the selected flap design. The purpose of the flap design of minimally invasive periodontal surgery is to overcome the drawbacks of conventional periodontal surgeries decreasing the surgical trauma, improving the clot stability, reducing patient discomfort post operatively and minimizing the surgical chair time (Aslan, Buduneli, & Cortellini, 2017b) Modified Minimally Invasive Surgical Technique (M-MIST) is considered one of the latest minimally invasive techniques that have been used in the treatment of intraosseous defects, this technique however entails an incision over the defect-associated interdental papilla that may jeopardize the volume and complex vascular integrity of the interdental tissues, lacking the special flap design that would emphasis clot stability for better wound healing. Where a new surgical technique turned entire papilla preservation has been developed for protection of the wound without affecting the vascularity of the area. (Pierpaolo Cortellini & Tonetti, 2015) This randomized clinical trial compared the clinical and radiographic efficacy of entire papilla preservation surgical technique (EPP) to Modified minimally invasive surgical technique (M-MIST) in the treatment of periodontal intraosseous defects in stage III periodontitis patients.

Intervention

Procedure:
• Entire Papilla Preservation technique
A minimally invasive technique that allow access to the intrabony defect without affecting the interdental papilla related to it
• Modified Minimally invasive Surgical Technique
a minimally invasive technique that allow access to the intrabony defect area from the buccal aspect through a horizontal incision below the papilla without elevating it.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical attachment Level gain (CAL gain)	CAL gain will be determined by measuring the distance from the cemento-enamel junction to the base of the pocket using a UNC 15 periodontal probe.	12 months
Secondary	Pocket depth (PD)	Probing depth will be measured from the gingival margin to the base of the periodontal pocket using a UNC 15 periodontal probe.	12 months
Secondary	Gingival recession (GR)	Gingival recession will be measured using UNC periodontal probe from the cemento-enamel junction till the gingival margin (Ainamo & Bay, 1975).	12 months
Secondary	Radiographic defect fil	The depth of intra-bony defect (IBD) will be measured from the alveolar bone crest to the base of the defect to detect the amount of bone fill Radiographs will be scanned and the radiographic IBD depth will be measured by a computer-aided software program	12 months
Secondary	Gingival bleeding score	Gingival bleeding score will be performed through gentle probing of the orifice of the gingival crevice from all four surfaces of all teeth using UNC Periodontal probe.; Recorded as (+) if bleeding is present or (-) if bleeding is absent.; If bleeding occurs within 10 seconds a positive finding is recorded and the number of positive sites is recorded and then expressed as a percentage of the number of sites examined	12 months
Secondary	Post-surgical patient satisfaction	Three questionnaires will be asked to determine patients' satisfaction with the outcome of surgery; Considering this was an elective operation, how likely would you be to recommend it to others?; If you had to make the decision again, how likely would you be to undergo this surgery'?; Considering everything, how satisfied are you with the outcome of your surgery; These questions could all be answered by the patient using a 7-point response scale where: Very Satisfied = 7; Not At All Satisfied = 1. (H. A. Kiyak et al., 1984)	12 months
