Determination of bacterial accumulation. a Dental plaque-disclosing photographs of the cervical portion of the M2 in mice. Older plaque is revealed in blue, newer plaque in pink. Scale bar 1 mm. b Quantification of anaerobic bacteria. Bacteria were extracted from recovered sutures and sterile paper points used to sample microbiota on the tooth surface and in the gingival crevicular (or periodontal pocket). Serial dilutions of bacterial suspensions were plated onto blood agar plates for anaerobic growth and CFU enumeration. Each symbol represents an individual mouse; small horizontal lines indicate the mean. *p < 0.05
