Which of the following is NOT typically included in periodontal treatment materials?

Toothpaste is not typically included in periodontal treatment materials because it is primarily a consumer product used for daily oral hygiene rather than a specialized tool or material specifically intended for professional periodontal treatment. In a clinical setting, dental professionals utilize ultrasonic scalers for effective plaque removal and calculus elimination from the teeth and periodontal pockets. Rubber cups are used in conjunction with polishing agents during dental cleanings to smooth the tooth surfaces and further remove biofilm. Local anesthetic may be administrated during periodontal procedures to ensure patient comfort, especially when deeper scaling is involved. Thus, while the other items play significant roles in periodontal therapy, toothpaste does not have a dedicated function in professional periodontal treatments.
