- Group1 : (-ve control group): SRP alone
- Group2: (+ve control group): SRP+ chitosan Nano-particles
- Group3: SRP + Curcumin-coated chitosan Nano-particles
- Group4: SRP+ hyaluronic acid -coated chitosan Nano-particle
All Patients will undergo Phase I therapy, which includes scaling and root planing using ultrasonic tips and gracey curettes. Additionally, mechanical oral hygiene instructions will be provided, and participants will be advised to refrain from using any mouthwash throughout the duration of the study.
Furthermore, patients within groups 2 to 4 will be subjected to an extra measure involving the application of the respective gel associated with their designated group. The gel will be administered on a weekly basis for duration of five weeks.
Clinical indices (plaque index (PI), gingival index (GI), clinical attachment level (CAL), and probing depth (PD)). Laboratory assessment will be done at baseline and final assessment( after 3 months) . tess will be for antioxdiant levels and TNF alpha

- Exclusion criteria: patients with recent history of periodontal treatment (within the last 3 months) patients with recent use of antibiotic (within the past 3 months, pregnant or lactating women, individuals who are malnourished and taking vitamin supplements, Patients who regularly use mouthwashes.
Method of gel application: a blunt 2ml syringe will be used to administer the gel sub-gingivally until the pocket is filled
Cervicular fluid collection :
This is done at baseline and after 12 weeks
- Insert absorbent paper points gently into the gingival crevice at the sulcus or pocket depth.
- Allow the absorbent material to remain in the crevice for a specific duration (1 minute) to enable the collection of gingival crevicular fluid.
- Carefully retrieve the paper points from the gingival crevice, ensuring that the collected fluid is preserved on the material.
- Place the paper points in eppendorf tubes
- Handle the samples with care to prevent contamination and promptly transport them to the laboratory for further analysis. If necessary, samples may undergo centrifugation to separate cells and debris from the fluid.
Periodontal assessment:
The following periodontal indices will be assessed at baseline, and after 12 weeks o Plaque Index according to Silness P. Loe H 1964
- Gingival Bleeding Index/Bleeding On Probing(BOP) according to Ainamo \& Bay 1975
- Probing pocket depth (PPD) is measured from free gingival margin to base of the pocket.
- Clinical attachment loss (CAL) is measured from cemento-enemal junction to base of the pocket. the determination of the sample size was guided by reference of similar articles. . Employing G power for the calculation, the sample size was determined with a 0.676 effect size, a two-tailed test, α error set at 0.05, and a power of 0.8, resulting in a total calculated sample size of 10 individuals in each group.
Pretreatment period Participants were informed about the purpose of the study and screened for eligibility. They also were informed about the treatment received and the steps done, including non-surgical treatment and gel application with the associated risks, possible effects, and other treatment options available. The participants understood this explanation in broad terms according to the rules of the ethical committee of the Faculty of Dentistry, Mansoura University. Additionally, they acknowledged that they would be required to attend the periodic recall visits and that they are legally competent to give written informed consent before performing any required steps.

Questions about this trial
What is this clinical trial studying?
A study testing curcurmin loaded on chitosan nano-particles, hyaluronic acid loaded on chitosan nano-particles and scaling and root planning in people with Periodontitis, run by Mansoura University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 20 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Probing pocket depth reduction (time frame: 12 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 May 2025; AzTrials last refreshed its copy on 8 Nov 2026.
