Baseline data was then collected, which included gingival indices, full mouth periodontal probing, clinical attachment levels, bleeding upon probing, tactile detection of subgingival calculus with an 11/12 explorer and visual detection of subgingival calculus using the periodontal endoscope in the randomly assigned endoscope quadrant.
