Contemporary periodontal therapy is structured into sequential phases, with non-surgical periodontal therapy (NSPT) forming the cornerstone of initial management. Following this phase, re-evaluation of periodontal status is critical to determine treatment outcomes and guide further intervention, including surgical therapy if required (1,2).\n\nRe-evaluation phase serves multiple purposes: it allows assessment of tissue response to therapy, measurement of reductions in probing pocket depth (PPD), gains in clinical attachment level (CAL), and evaluation of patient compliance with oral hygiene practices. It also aids in identifying residual pockets or persistent inflammation that may necessitate additional treatment (1,3). Despite its clinical importance, the optimal timing of re-evaluation remains inconsistently defined in the literature (1). Generally, current literature utilizes a timing frame from 1-3 months; up to 9 months (3,4). Current clinical guidelines, including those from the European Federation of Periodontology (EFP), generally recommend assessing whether the end points have been achieved; no periodontal pockets ≥ 5mm with bleeding on probing and no pocket ≥ 6mm (5).\n\nEmerging evidence suggests that certain clinical improvements, particularly reductions in inflammation and bleeding on probing (BOP), may occur as early as 4 weeks following therapy, raising questions about whether earlier re-evaluation could be clinically beneficial (2,3). Early reassessment may allow for more timely identification of non-responding sites, enabling prompt intervention and potentially improving overall treatment outcomes. Conversely, other studies indicate that full periodontal healing and maturation of tissues may require longer periods, supporting delayed re-evaluation intervals (1,2,3).\n\nFurthermore, patient-related factors such as systemic health, smoking status, and baseline disease severity may influence healing dynamics and thus the appropriate timing for reassessment (1). The heterogeneity of these factors highlights the potential need for a more individualized approach to re-evaluation rather than a fixed universal timeframe.\n\nDespite these considerations, there is a notable lack of high-quality comparative studies directly evaluating short-term versus conventional re-evaluation intervals following NSPT. Most available studies focus on treatment outcomes rather than the timing of reassessment itself. This creates a significant gap in the literature, particularly regarding whether earlier re-evaluation could enhance clinical decision-making, improve patient outcomes, or optimize resource utilization in clinical practice.\n\nIn addition, with increasing emphasis on minimally invasive and patient-centered care, there is a growing need to refine periodontal treatment protocols to ensure efficiency without compromising effectiveness. Determining the optimal timing of re-evaluation could contribute to improved treatment planning, reduced disease progression, and enhanced long-term periodontal stability.\n\nTherefore, this study aims to address this gap by investigating the effectiveness and clinical implications of shorter re-evaluation intervals following periodontal therapy, compared to conventional timeframes.",[28,29,30],"Periodontal Diseases","Periodontitis (Stage 3)","Subgingival Debridement",[32],"periodontal disease","NOT_YET_RECRUITING","2026-06-25",{"date":36,"type":37},"2026-07-01","ACTUAL",{"date":39,"type":22},"2026-06-01",{"date":41,"type":22},"2027-02-15",{"name":43,"class":44},"Gulf Medical University","OTHER",1,{"id":47,"slug":48,"hasResults":11,"nctId":49,"briefTitle":50,"officialTitle":51,"acronym":52,"eligibilityCriteria":53,"healthyVolunteers":11,"sex":17,"minAge":54,"maxAge":55,"enrollmentInfo":56,"targetDuration":4,"studyType":23,"phases":58,"briefSummary":59,"conditions":60,"keywords":63,"overallStatus":67,"whyStopped":4,"lastUpdateSubmitDate":68,"lastUpdatePostDateStruct":69,"startDateStruct":71,"completionDateStruct":73,"leadSponsor":75,"locationsCount":45},"100644677","omega-3-plus-low-dose-aspirin-in-smokers-with-stage-iii-periodontitis-100644677","NCT07673185","Omega-3 Plus Low-Dose Aspirin in Smokers With Stage III Periodontitis","Clinical and Biochemical Evaluation of the Effect of Omega-3 Fatty Acids Plus Low-Dose Aspirin as an Adjunct to Non-Surgical Periodontal Therapy in Smoker Patients With Stage III Periodontitis: A Randomized Double-Blind Placebo-Controlled Clinical Trial","OASP","Inclusion Criteria:\n\n* \\- Male or female smokers aged 30 to 50 years.\n* Diagnosed with Stage III periodontitis according to the 2017 World Workshop classification.\n* Probing pocket depth (PPD) ≥ 5 mm.\n* Clinical attachment loss (CAL) ≥ 5 mm.\n* Presence of at least 20 natural teeth.\n* Willing and able to provide written informed consent.\n\nExclusion Criteria:\n\n* \\- Systemic diseases affecting periodontal health.\n* Pregnancy or lactation.\n* Periodontal treatment within the previous 6 months.\n* Use of antibiotics or anti-inflammatory drugs within the previous 6 months.\n* Allergy or hypersensitivity to omega-3 fatty acids or aspirin.\n* Long-term anticoagulant therapy.\n* History of gastric ulcer or bleeding disorders.\n* Participation in another clinical trial within the previous 3 month","30 Years","50 Years",{"count":57,"type":22},40,[25],"This randomized double-blind placebo-controlled clinical trial aims to evaluate the clinical and biochemical effects of omega-3 fatty acids combined with low-dose aspirin as an adjunct to scaling and root planing (SRP) in smoker patients with Stage III periodontitis.

The primary objective is to assess changes in key periodontal parameters including probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI) over a defined follow-up period. Participants will be randomly assigned to two groups: one receiving standard NSPT alone and the other receiving NSPT combined with subgingival application of I-PRF. The study seeks to determine whether the adjunctive use of I-PRF can enhance periodontal healing and improve clinical outcomes compared to conventional therapy alone.",[29],[166,263,264,265],"Injectable Platelet Rich Fibrib","Non-surgical Periodontal Therapy","Adjunctive Therapy","2025-07-21",{"date":268,"type":37},"2025-07-29",{"date":270,"type":22},"2025-07",{"date":272,"type":22},"2025-10",{"name":274,"class":44},"Cairo University"]
