Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 35 to 70 years
- Women only
- Healthy volunteers accepted
- Adult, Older adult
Who may be able to join
- All patients were diagnosed with periodontitis (P) The inclusion criteria were:Loss of clinical insertion (CAL) ≥ 5mm and PD probing depth ≥ 6mm in ≥ 30% of sites; ≥20 teeth; radiographic bone loss that extends to the middle level of the root; presence of supragingival and subgingival calculus according to the severity of periodontal damage.

About this study
Official title: Effects of Non-surgical Periodontal Treatment on the Gingival Crevicular Fluid Cytokine Profiles in Breast Cancer Patients Undergoing Chemotherapy
Aim: This study evaluated the effects of non-surgical periodontal therapy (NSPT) on the cytokine profile and the correlation to clinical parameters of patients undergoing chemotherapy for breast cancer.
Materials and methods: 40 patients were allocated: periodontitis patients (P) (n=20) and breast cancer with periodontitis patients (CAN/P) (n=20). The clinical parameters: probing depth (PD), clinical attachment level (CAL), plaque index (PI), Bleeding on probing (BOP) and levels of IFN-γ, IL-4, IL-10, TGF-β, IL-17, IL-2, IL-6, IL-1β and TNF-α in gingival crevicular fluid (GCF) were evaluated at baseline, 45 and 180 days after therapy.
Read the detailed description
The NSPT, which consisted of subgingival debridement - scaling and root planning (SRP) under local anesthesia. On average, the treatment of the entire oral cavity was completed within four sessions (sessions of 50 minutes). The SRP was performed by one experienced periodontist (KRVV) using Gracey curettes (Hu-Friedy MFG. Co. Inc., Chicago, IL, USA), ultra-sonic devices (Bob-Cat, Dentsply/Cavitron, Long Island City, NY, USA) and, if necessary, with multilaminated drills.

Questions about this trial
What is this clinical trial studying?
A study testing Non surgical periodontal Treatment in people with Mammary Neoplasm, Human and Periodontal Diseases, run by University of Sao Paulo.
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 1 inclusion and 1 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: finished, as of the sponsor's last update on 22 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Cytokines (time frame: baseline, 45 days, 180 days). 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 22 Jun 2020.
