Table I.
Clinical sample site parameters.
| Parameter | Disease sites (n=52) | P-value | Non-disease sites (n=10) | P-value | P-value | |
|---|---|---|---|---|---|---|

| PPD (mm) | 4.9±0.1 | 3.4±0.2 | <0.001a | 0.5±0.2 | <0.001c | <0.001d |

Statistics were calculated using
a
the Paired Samples T-Test,
b
McNemar Test,
c
Independent Samples T-Test
c
comparison between disease sites prior to treatment and non-disease sites;
d
comparison between disease sites following treatment and non-disease sites, and Fisher’s Exact Test
e
comparison between disease sites prior to treatment and non-disease sites;
f
comparison between disease sites following treatment and non-disease sites.
P<0.05 indicates a statistically significant difference. PPD and CAL values are expressed as the mean ± SEM. BOP, bleeding on probing; CAL, clinical attachment level; PPD, probing pocket depth.
