Scaling and Root Planing and Subgingival Calculus: A Re-evaluation

Thursday, April 7     8:30 - 11:30 AM

Course Description:  cobb cardA discussion of subgingival calculus will be presented, using neglected older research and newer findings that, when considered collectively, reinforces the role of subgingival calculus in the progression and recurrence of periodontitis.  Based on a review written by Dr. Charles Cobb and John Sottosanti (Journal of Periodontology, 2021), the evidence for the problem of residual calculus, i.e., “fractured calculus”, will be presented and why “blind SRP” in specific cases is not sufficient treatment.  The debate of subgingival debridement vs. SRP and ultrasonic/sonic vs. manual instrumentation will be discussed. Lastly, the association of persistent periodontal inflammation with various systemic disease and the important role of the dental hygienist in education and management of the perio/systemic relationship.

Learning Objectives:

  1. Be familiar with the physical structure and microbiology of subgingival calculus.
  2. Be familiar with the various modes of calculus attachment to a diseased root surface and the clinical significance of "fractured calculus."
  3. Know the objectives and limitations of non-surgical periodontal therapy (i.e. scaling and root planing) in terms of long-term treatment outcomes.
  4. Know the relationship between periodontitis, subgingival calculus and dysbiotic biofilms and their relationship to atherosclerosis, stroke, Alzheimer's disease, and rheumatoid arthritis.
