Bleeding on probing (dichotomy BOP: yes or no) at sites with PD ≥ 4 mm at T1 was considered as a dependent variable (number of included cases: n = 1772). Clinical attachment level (CAL); hard deposit (HD); test teeth without periodontal endoscopy treatment (nPE); test teeth with periodontal endoscopy treatment (PE); pocket probing depth (PD); baseline (T0); reevaluation visit after the end of nonsurgical periodontal therapy (T1). Regression coefficient (B). Standard error (SE). Odds ratio (OR): significant at (in bold).
