44 subjects ranging in age from 14–71 years were measured at 6 sites per tooth for gingival redness, plaque accumulation, suppuration, bleeding on probing, pocket depth and attachment level. Subgingival temperatures were measured at the same 6 sites per tooth using a periodontal temperature probe (Perio‐temp TM , Abiodent SM , Danvers, MA). This instrument was also used to measure each subject's sublingual temperature in order to compute the differences between sublingual and Subgingival temperature. Relationships were sought between the baseline clinical parameters and the temperature variables in subjects and at sites. The mean and standard deviation of the sublingual temperatures for the 44 subjects was 36.6±0.4°C (range 35.8–37.6°C). The mean of each subject's mean whole mouth subgingival temperature was 1.9°C lower, 34.8±0.6°C (range 33.4–36.1°C). The differences of the mean subgingival temperature from sub‐lingual ranged from ‐0.8 to ‐3.2°C (average ‐1.9 + 0.5°C). Mean temperature difference for a subject correlated with % of sites with plaque (r s = 0.45), redness (r s = 0.33), bleeding on probing (r s = 0.44), % of sites with attachment level > 3 mm (r s = 0.44), mean pocket depth (r s = 0.44) and mean attachment level (r s = 0.39). There were higher mean temperatures at sites exhibiting or not exhibiting plaque (35.0, 34.5°C), redness (34.9, 34.6), bleeding on probing (35.1, 34.7) and suppuration (35.4, 34.8). Sites with pockets <4, 4–6 and >6 mm had mean temperatures of 34.6, 35.2, 35.8°C, respectively. Site temperature showed a similar relationship with attachment level. The data indicated that subjects differed in their mean subgingival temperature and that some of the differences were indicative of the extent of prior periodontitis and current levels of gingival inflammation. Similarly, temperature at a site related to location of the site in the mouth, pocket depth, attachment level and inflammatory status.
