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.

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.

"Comparison of Spirulina Gels for Treating Stage II Grade B Periodontitis"

This randomized controlled clinical study investigates the effectiveness of Spirulina gel and Spirulina nanoparticles gel in treating Stage II Grade B periodontitis. The research aims to compare the two formulations in terms of clinical, radiological, and biochemical outcomes, such as pocket depth reduction, alveolar bone density improvement, and inflammatory marker levels. The study seeks to provide insights into the potential of Spirulina-based therapies for enhancing periodontal health.
