Table 8: Mean values ± standard deviation of osteocalcin levels in the gingival crevicular fluid (ng/ml) in Group I treated with standard scaling and root planning plus 20mg doxycycline twice/day for 3 months; group II treated with standard scaling and root planning plus 30mg CoQ10 twice/day for 3 months; group III treated with standard scaling and root planning plus 20mg doxycycline and 30mg CoQ10 twice/day for 3 months; group IV treated with standard scaling and root planning only. Letters a, b, and c refer to the degree of significance at *P<0.05; significant difference was found among groups marked by different letters (a,b,c) and no significant difference was found among groups marked by similar letters.
