Brief Summary
This is a prospective cohort study that aims to describe the difference in terms of percentage of closed pockets (PPD \<5 mm and no BOP) when performing the periodontal re-evaluation at 3-4, 6-8 and 12 months. Fifty-two, ≥18-year old, otherwise healthy, periodontitis patients will be recruited at Centro di Odontoiatria, Università di Parma.

Outcome Measures
Primary Outcomes (1)
changes in percentage of closed pockets (PPD <5 mm and no BOP)
From baseline to 3-4; 6-8 and 12 months
Secondary Outcomes (8)
Changes in probing pocket depth (PPD), recession (REC) and clinical attachment level (CAL)
From baseline to 3-4; 6-8 and 12 months
Changes in the percentages of sites with PPD reduction ≥2mm
From baseline to 3-4; 6-8 and 12 months
Changes in the percentages of sites with CAL gain ≥2mm
From baseline to 3-4; 6-8 and 12 months
Changes in the percentage of deep pockets (PPD≥6 mm)
From baseline to 3-4; 6-8 and 12 months
Evaluation of global changes in quality of life
4-6 weeks; 3-4 months; 6-8 months; 12 months
- +3 more secondary outcomes
Study Arms (1)
Non-surgical periodontal therapy
Interventions
NSPT will be performed following the principles of minimally invasive non-surgical therapy (MINST) described by Nibali et al. (Nibali et al., 2015, Nibali et al., 2019)
Eligibility Criteria
Patients affected by periodontitis
You may qualify if:
- Systemically healthy males and females ≥18 years old
- Willingness to read and sign a copy of the Informed Consent Form after reading the Patient Information Sheet, and after the nature of the study has been fully explained
- Clinical evidence of periodontitis, defined as the presence of interdental clinical attachment loss detectable at ≥2 non-adjacent teeth or buccal or oral clinical attachment loss ≥3mm with pocketing \>3 mm detectable at ≥2 teeth (Tonetti et al., 2018)
- Not having received subgingival instrumentation within the previous 12 months
You may not qualify if:
- Medical history that includes serious medical conditions or transmittable diseases (e.g. serious cardiovascular disease, organ transplant, renal failure, AIDS, viral etc.).
- Antibiotic, anti-inflammatory or anticoagulant therapy during the month preceding the baseline exam.
- In treatment with drugs that induce gingival overgrowth
- History of conditions requiring prophylactic antibiotic coverage prior to invasive dental procedures
- History of alcohol or drug abuse.
- Self-reported pregnancy or lactation (this criterion is due to oral tissue changes related to pregnancy and nursing, which can affect interpretation of study results).
- Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with trial participation or investigational product administration or may interfere with the interpretation of trial results and, in the judgement of the investigator, would make the subject inappropriate for entry into this trial.

Biospecimen
Non-stimulated saliva sample will be collected at certain visits (baseline, 3-4, 6-8 and 12 months post NSPT), and will be stored (frozen) for analysis. Samples of GCF will be collected from the deepest sites (maximum of 5) at baseline, 3-4, 6-8 and 12 months post NSPT. GCF will be collected prior to periodontal probing to avoid contamination by blood.

Data Sharing
- IPD Sharing
- Will not share
Centro di Odontoiatria is the sponsor for this study. We will be using patient information in order to undertake this study and will act as the data controller for this study. This means that we are responsible for looking after patient information and using it properly. We will keep identifiable information for 20 years after the study has finished. The only people within the Centro di Odontoiatria who will have access to information that identifies the patients will be people who need to contact them about the research study, and make sure that relevant information about the study is recorded for their care, and to oversee the quality of the study or audit the data collection process. The people who analyse the information will not be able to identify patients and will not be able to find out their name or contact details.
