FIG. 3.

Opsonization of P. gingivalis with P. gingivalis-specific IgG prior to oral challenge inhibits P. gingivalis-elicited oral bone loss. Groups of BALB/C mice were either unchallenged (None), were orally challenged with P. gingivalis (A7436), or were gavaged with P. gingivalis opsonized with control IRR-IgG or P. gingivalis-specific IgG. Linear measurements were obtained from the cementum-enamel junction to the alveolar bone crest from the maxillary molars at 14 landmark sites per mouse. *, P < 0.05 by the Student t test versus control mice (None); NS, not significant versus control (None).
