Periodontal Therapy: Patient Outcomes-Based or Profit Center-Based?

Multiple recent articles have called for outcomes-based and patient-centered guidelines for periodontal therapy.1-6 Simply put, periodontal therapy must be in accord with evidence-based treatment and doing what is right for the patient at the clinical level. With this in mind, the present authors contend that many patients with periodontal disease are not receiving acceptable and timely treatment and disease management.

Calculus as a Risk Factor for Periodontal Disease: Narrative Review on Treatment Indications When the Response to Scaling and Root Planing Is Inadequate.

BACKGROUND: Based on the 2018 classification of periodontal disease, a series of articles have been published describing the decision points of periodontal therapy and how the findings collected at those decision points can be used as guidelines for periodontal therapy. The articles are reviewed with a focus on the finding of inadequate calculus removal at the decision points and how that finding impacts treatment outcomes. METHODS: A narrative review of the literature discussing the influence of calculus on inflammation was performed and the effects of inadequate removal of calculus during periodontal therapy were analyzed in light of the 2018 classification of periodontal disease, the decision points of periodontal therapy, and the guidelines of periodontal therapy. RESULTS: The published literature supports that calculus is a major risk factor for periodontal inflammation. Recent studies indicate that the pathologic risk of calculus goes beyond the retention of biofilm and may represent a different pathophysiologic pathway for periodontal disease separate from the direct action of biofilm. The inadequate removal of calculus is a factor in the failure of periodontal therapy. CONCLUSIONS: The inadequate removal of calculus plays an important role in the frequent failure of non-surgical periodontal therapy to eliminate inflammation.

Clinical Decisions Based on the 2018 Classification of Periodontal Diseases.

The absence of widely accepted treatment decision points for the management of periodontitis can be problematic for the dental profession and patients. After conducting a thorough review of published peer-reviewed studies, the authors developed basic therapeutic decision points for the management of periodontitis based on the 2018 classification of periodontal diseases. These decision points were utilized to outline appropriate treatments, which include: patient commitment to a thorough daily self-care regimen, the definitive elimination of etiological factors, professional treatment that includes the complete removal of residual bacterial biofilm (plaque), the definitive removal of both supragingival and subgingival calculus, and, in advanced disease, possible tissue augmentation and regenerative surgery. Advanced therapies to accomplish an acceptable therapeutic end point are indicated in stage III and stage IV periodontitis. The presented decision points for the treatment of periodontitis offer a basis for the ethical care and management of patients in all stages of periodontitis.

A re-evaluation of scaling and root planing.

BACKGROUND: Extensive reviews on the role of scaling and root planing (SRP) in the treatment of periodontitis have been previously published. This commentary will address the importance of subgingival calculus in the progression and treatment of periodontitis and addresses factors that make the execution of a "definitive" SRP a critical part of therapy. METHODS: A search for articles, using keywords relevant to the subject , (e.g., periodontitis, dental scaling, root planing, dental calculus, biofilm, inflammation) was conducted using PubMed, Ovid Medline, Cochrane Reviews and the ADA Center for Evidence Based Dentistry data bases. Additionally, references cited in relevant articles were also considered. RESULTS: Surfaces of subgingival calculus are covered with a biofilm of metabolically active bacteria. Periodontal inflammation is clearly related to the presence of calculus and biofilm. The primary goal of SRP is removal of subgingival calculus and biofilm deposits to create a biologically compatible root surface and reduce the inflammatory burden. Current evidence suggests that inflammation associated with periodontal infections affects both the immediate oral environment and the patient's systemic health. CONCLUSION: SRP is still critical to the treatment of periodontitis. SRP involving deep probing depths (≥ 5 mm) and root surfaces with anatomical and surface irregularities, regardless of the type of instrumentation, requires time, exceptional skill and perseverance, and patient compliance with periodontal maintenance. Sites with persistent nonresponding probing depths and signs of inflammation following a definitive SRP, should be considered for surgical intervention.
