“…In this case, the observed P02 values would be higher than those reported here. Recent reports indicate that the temperatures of pockets '5 mm range from 34 to 360C (28). For purposes of the present study, the temperature of the pocket was assumed to be 35°C.…”

“…The sterile, disposable electrodes were calibrated before every measurement to the actual PO2 in the atmosphere, i.e., 21% of the atmospheric pressure minus the partial pressure of water vapor (47 mmHg at 37°C; 1 mmHg = 133.3 Pa). Since the calibration temperature differed from the temperature in the periodontal pockets, which is about 34 to 36°C (28), an adjustment on the monitor to a temperature of 35°C was performed.…”

The predominance of anaerobic bacteria in subgingival plaque samples suggests that the pocket environment is anaerobic. In the present investigation, a small oxygen tension (PO2) electrode was inserted into the base of the pocket and the P02 was recorded. In addition, the plaque in these pockets was examined culturally and microscopically. The oxygen tension at the bottom of 36 pockets (5 to 10 mm in depth) ranged from S to 27 mmHg (1 mmHg = 133.3 Pa) with a mean value of 13.3 mmHg. Moderate pockets (5 and 6 mm) exhibited a mean PO2 of 15.7 mmHg, which was significantly higher than the 12.0 mmHg found in the deeper pockets. The deep pockets had higher percentages of spirochetes and Bacteroides intermedius, whereas the moderate pockets had elevated proportions of Actinomyces naeslundii and Streptococcus mutans. The sites with oxygen tensions equal to or less than 15 mmHg had significantly higher percentages of spirochetes, whereas the microaerophilic Capnocytophaga species were found in pockets with a P02 greater than 15 mmHg. The presence of bleeding in the pocket was associated with higher proportions of B. intermedius, Capnocytophaga sp., and A. naeslundii. These P02 readings of periodontal pockets indicated that there is a spectrum Of PO2 values which seem to define, in a general way, the microbiological composition of the pocket.on July 16, 2020 by guest http://iai.asm.org/ Downloaded from RESULTSThe PO2 at the bottom of the untreated pockets ranged from 5 to 27 mmHg, with a mean value of 13.3 mmHg.

“…To understand how polymorphonuclear leukocytes may function outside the body (that is, above the epithelium), certain features of the gingival sulcus and the gingival crevicular fluid are relevant. The mean temperature of the healthy gingival sulcus is 33.920.4"C (158); and this temperature elevates to 35-37°C as pocket depth increases (147). Therefore, crevicular temperatures should support cellular function.…”

“…In another study [16], a mean sublingual temperature of 36.5°C was recorded in 104 periodontal pockets, with a probing depth in the range of 3–9 mm, in which only 29 pockets had a probing depth of > 7 mm. In our study, a mean sublingual temperature of > 37.5°C was noted in the subjects with severe periodontitis.…”

Background and Objectives: The purpose of this study was to assess pyrexia and sickness behavior such as anxiety, depression, lethargy, and weight loss in subjects with chronic periodontitis, and evaluate inflammatory mediators such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in the patients with fever. Methods: This was a cross-sectional study that consisted of 150 chronic periodontitis and 150 healthy subjects. Sublingual and subgingival temperatures were assessed using a digital temperature probe. Associated sickness behavior was assessed for all the subjects. Pathological tests, i.e., ESR and CRP were done for subjects with fever. Results: Evaluating the presence of fever with the severity of periodontal disease, 66.7% of the subjects with fever were in the group diagnosed with severe periodontitis, 20.4% had with moderate periodontitis, and 5.3% were in the healthy group. Subjects diagnosed with periodontitis comprised 66.2% of the subjects with higher (i.e., > 36.3°C) subgingival temperatures and healthy subjects made up the remaining 33.8% (p < 0.001). A correlation between the sublingual and subgingival temperature with the Pearson ρ correlation coefficient of 0.227 (p < 0.001) was observed. A statistically significant mean value of 37.05 ± 11.24 of ESR and 1.59 ± 1.11 mg/L of CRP was reported amongst the subjects with fever (p < 0.001). The association of sickness behavior with the severity of periodontitis was found to be significant: depression 40.006, anxiety 50.857, reported weight loss 76.463, and lethargy 141.581 (p < 0.001). Discussion and Conclusion: The study demonstrated that there is a significant increase in the sublingual temperature amongst patients with severe chronic periodontitis. The subgingival temperature has a positive correlation with the sublingual temperature. There was a linear trend of an association of sickness behavior with the severity of chronic periodontitis. A significant increase in the circulating inflammatory mediators, CRP and ESR, were noticed in subjects with elevated body temperature.
