Study Notes

Nonsurgical Periodontal Therapy (NSPT)

  • NSPT stands for Nonsurgical Periodontal Therapy, which includes all nonsurgical procedures aimed at controlling periodontitis and gingivitis.
  • Primary objective of NSPT is to eliminate periodontal disease and maintain health through professional and patient self-care.

Indications and Goals

  • NSPT is indicated for ALL patients with plaque-associated gingivitis or chronic periodontitis.
  • Key goals of NSPT include minimizing bacterial challenges, controlling local and systemic risk factors, and stabilizing attachment levels.
  • The ultimate goal of NSPT is to stabilize attachment levels.

Procedures and Techniques

  • Instrumentation methods include scaling (traditional term for removing plaque and calculus) and root planing (removal of cementum and toxins).
  • Emerging terms such as periodontal debridement and deplaquing focus on removing bacterial plaque from pocket spaces and subgingival areas.
  • Root planing requires long, light strokes; more strokes are often needed compared to traditional methods.

Effectiveness and Outcomes

  • Efficacy of scaling and root planing varies by pocket depth:
    • 1-3 mm sulcus depths show 83% effectiveness.
    • 4-6 mm pockets demonstrate 43% effectiveness.
    • Pockets ≥7 mm show reduced effectiveness at 32%.

Healing and Follow-Up

  • True importance of scaling and root planing lies in reducing the critical mass of residual deposits.
  • Endpoint of instrumentation is returning to soft tissue health, which involves the formation of a long junctional epithelium without new bone or periodontal ligament formation.
  • Probing depth reductions average 2 mm for pockets ≥7 mm and 1 mm for 4-6 mm pockets.

Reevaluation and Critical Decision-Making

  • Tissue healing is assessed at least one month post-SRP, and re-evaluation should occur 4-6 weeks after instrumentation.
  • Non-responsive sites exhibit signs of inflammation, more attachment loss, and bleeding; initial steps include re-exploration for residual deposits.
  • Critical decision-making includes determining the need for additional NSPT, evaluating surgical options, and referrals to specialists for severe cases.

Maintenance and Patient Involvement

  • Periodontal maintenance programs aim to prevent recurrence and are essential for all patients with chronic periodontitis after NSPT.
  • Host factors must be considered when reassessing non-responsive patients.
  • Patients play a critical role in self-care, acting as co-therapists alongside professionals.

Tissue Impact and Aids

  • Interdental tissues are typically the first damaged by periodontal diseases, highlighting the need for effective interdental aids in maintenance care.
