Morphometric measurements of horizontal area alveolar bone resorption and Intrabony defects on the buccal and palatal/lingual surfaces of all molars.

Morphometric analysis of the buccal and palatal/lingual surfaces of maxillae and mandibles were done post-euthanasia after 12 weeks of infection, including an overlapping 6 weeks of treatment. The area of total bone resorption was measured in mm2. The last column shows the percent intrabony defect found in all jaws. Percentages indicate number of sites found to contain intrabony defects per 72 total sites analyzed per group. All groups were compared to the Pg+Td+Tf (P. gingivalis + T. denticola + T. forsythia) group for statistical significance. Asterisks indicate the following P-values when compared to controls *P<0.05; **P<0.005; ***P<0.0001. Values are means ± standard deviations of the bone resorption measured or (n) number of animals. Broken jaws or jaws missing teeth were excluded and reflected in (n).
