PeriodonticsThe cementum near the cementoenamel junction (CEJ) is indeed very thin, making it more susceptible to removal during instrumentation. Additionally, cementum can be softer than subgingival calculus, and in cases of periodontal disease, it may become necrotic.

EndodonticsCarbamide peroxide is the standard bleaching material used for night guard vital tooth bleaching (at-home bleaching). It typically comes in 10-15% concentration and breaks down slowly to release 3% hydrogen peroxide over several hours. This provides: 1) Extended contact time for effective bleaching, 2) Lower concentration reduces sensitivity, 3) Controlled release ensures patient safety, 4) Better patient compliance due to comfortable application. Superoxol (30% H2O2) is too strong for home use.
