Development and Validation of the Periodontal Map Derived From IOS and CBCT Registration for Diagnosis and Treatment Planning in Moderate-to-severe Periodontitis

This prospective diagnostic study aims to validate the clinical utility of a "Periodontal Panoramic Map" generated by the PerioAI V2.0 system, an artificial intelligence-based platform that integrates intraoral scans and cone-beam CT data, for preoperative diagnosis and surgical planning in patients with moderate to severe periodontitis (Stage II-IV). Current clinical standards-manual probing and two-dimensional radiography-have inherent limitations in accurately visualizing complex three-dimensional bone defect morphology, leading to potential underestimation of disease severity and suboptimal surgical outcomes. Building upon our team's previously published high-precision PerioAI V1.0 system, this study will enroll 80 patients requiring periodontal surgery. Preoperative intraoral scans and cone-beam CT images will be acquired as part of routine care, and the PerioAI V2.0 system will automatically generate a "Periodontal Panoramic Map" with intelligent outputs including probing depth, clinical attachment loss, bone defect morphology classification, furcation involvement grading, and automated measurements of key parameters such as intra-bony defect depth and width. These automated diagnostic results will be compared against the gold standard of full mouth clinical examination and intra-operative direct measurements and observations obtained during periodontal surgery under strict blinded conditions. The primary outcome measures are the accuracy of bone defect morphology classification and the agreement between automated and intra-operative linear measurements assessed by intraclass correlation coefficients and Bland-Altman analysis. Secondary outcomes include accuracy of probing depth, clinical attachment loss, periodontitis staging and grading, furcation involvement grading and treatment planning. This study will provide critical evidence supporting the paradigm shift in periodontal surgery from experience-dependent assessment to data-driven precision medicine, ultimately offering clinicians an intuitive, quantitative, and three-dimensional visualization tool for optimized surgical decision-making.

Blood Glucose Screening in Patients With Advanced Periodontits: the Role of Specialist Periodontal Care in Identifying Hyperglycaemia and Supporting Patient Centered Treatment

Periodontitis is a chronic inflammatory disease and individuals with advanced periodontitis are at increased risk of hyperglycaemia. Bacterial plaque, smoking as elevated blood glucose levels are considered key modifiable risk factors for periodontal disease progression. Conventional periodontal care aims to remove and control bacterial deposits and to smoking cessation. Despite the bidirectional relationship, where periodontitis may also contribute to impaired glycaemic control, glycaemic status is rarely niether assessed nor adressed in dental care. The aim of this project is to implement and evaluate routine blood glucose testing as part of the periodontal examination in specialist dental care. Patients diagnosed with advanced periodontitis (Stage III or IV according to the current classification) will be offered capillary blood glucose testing during their periodontal assessment. The objectives of this study are to determine the prevalence of hyperglycaemia among patients with advanced periodontitis and to evaluate clinician-reported and patient-reported experiences of routine blood glucose testing as part of the periodontal assesment in specialist periodontal care.

Clinical and Laboratory Evaluation of Resveratrol Loaded Nanoparticles in the Treatment of Periodontitis: A Randomized Controlled Clinical Trial

The Aim of this study is to test the effectiveness of locally applied resveratrol as an adjunct to scaling and root planing in the treatment of periodontitis (primary outcome) . Also to assess the level of COX-2 and superoxide dismutase (SOD) in the gingival crevicular fluid samples using the commercially available kits.

3-Month Clinical Trial of Liquid S-PRF in Periodontal Debridement for Periodontitis Stages II-IV

What is the purpose of this study? This study is to investigate the effect of a processed blood product in healing after treatment for gum disease. In addition to scaling \& root debridement (deep cleaning) that is the standard treatment for periodontitis, this study will test the effectiveness of patient's processed blood in improving healing of diseased gums. What are the procedures to be followed? First, all patients will undergo dental check-up and X-ray imaging for suitability as a participant for the project. For participants who are eligible and included into study, upper \& lower jaws models will be made, and each will be given oral care kit \& instructions. The next appointment will be given for scaling \& root debridement with local numbing agent in one day. Towards the end of the treatment, a small amount (20 mℓ) of blood will be collected and spun to produce liquid platelet-rich fibrin that is then used to flush the treated gum pockets in half of the mouth. For the treated gum pockets in the opposite half of the mouth, sterile salt water (saline) will be used instead for comparison. Then, follow-up appointments are at monthly intervals until 3 months. Who should enter the study? Symptoms of gum disease include bleeding and/or receding gums, tooth/teeth appearing longer or feeling shaky/loose/weak, formation of large amount of calculus and/or black/empty space between teeth, frequent/recurrent gum swelling/pus, and/or bad breath.

Comparative Effects of Two Oral Antiseptics Used as an Adjuvant in the Treatment of Periodontitis

The focus of this study is on two types of mouthwashes - one containing a chlorhexidine (CHX) at 0.2% (CHX), and the other one containing CHX at a lower concentration of 0.12% with cetylpyridinium chloride (CPC). Both mouthwashes are used to help in the treatment of gum disease. CHX has been known for a long time for its effectiveness against plaque and mouth inflammation. It could inhibit and even kill them. However higher concentrations of CHX comes with unwanted side effect including altered taste, teeth staining and irritation in the mouth. Interestingly, these side effects seem to occur less frequently when a lower concentration CHX solution is used. CPC also combats bacteria by adhering quickly to the surfaces inside your mouth, although it has less substantivity than CHX, it has been shown to reduce plaque and gum inflammation effectively, and it typically causes fewer side effects than CHX. We hypothesize that this new formulation of CHX 0.12%+CPC mouthwash is non-inferior to CHX 0.2% in terms of its anti-plaque and anti-inflammatory properties while presenting with less side effects after 21 days of use. Microbiological samples and fluids from periodontal pockets will be collected before and after treatment for analysis of microbiological effects.

Treatment of Periodontal Intrabony Defects With Liquid Platelet-Rich Fibrin Mixed With Denaturated Albumin Gel (ALB_PRF)

The objective of study also is to assess radiographic linear defect depth, and radiographic defect bone density following the application of liquid Platelet-Rich Fibrin (PRF) mixed with denaturated Albumin gel (ALB-PRF) or with bone allograft in periodontal intrabony defects. Patients and methods: 28 patients will be selected from the outpatient clinic in the Oral Medicine and Periodontology Department, Faculty of Dentistry, Mansoura University according to Pre-operative CBCT that will be used to evaluate the bone destruction pattern. According to the techniques that used in the treatment of periodontal bony defect, the participants will be randomly divided into 4 equal groups: Group I: will include 7 patients, in which the intrabony periodontal defects will be treated with open flap debridement and demineralized freeze-dried bone allograft (DFDBA) and mixed with liquid (PRF). Group II: will include 7 patients, in which participants will be treated with open flap debridement and liquid (PRF) mixed with denatured albumin gel (ALB-PRF) will be injected in periodontal intrabony defects. Group III: will include 7 patients, in which participants will be treated with open flap debridement, DFDBA mixed with liquid (PRF) and collagen membrane. Group IV: will include 7 patients in which participants will be treated with open flap debridement, DFDBA mixed with liquid (PRF) and ALB-PRF membrane.
