Elevated temperature, normally a characteristic of inflammation, is a potential indicator of periodontal disease. The present investigation examined the relationship of subgingival temperature and various indicators of gingivitis in rats with spontaneous gingivitis (SUS rat) and in control rats (RES rat). In 24 SUS rats with gingivitis, the subgingival temperature rose, but not in 6 SUS and 20 RES rats with healthy gingiva. Subjects with high mean subgingival temperatures had significantly higher mean percentages of Prevotella intermedia and Fusobacterium nucleatum than age-matched RES rats. The results show that dental plaque, including specific bacteria P. intermedia and F. nucleatum, can play some role in causing the elevated temperatures.
体温升高通常是炎症的一个特征，是牙周疾病的一个潜在指标。本研究调查了自发性龈炎大鼠（SUS大鼠）和对照大鼠（RES大鼠）龈下温度与各种牙龈炎指标之间的关系。在24只患有牙龈炎的SUS大鼠中，龈下温度升高，但在6只患有健康牙龈的SUS大鼠和20只RES大鼠中未升高。平均龈下温度较高的受试者中，中间普氏菌和具核梭杆菌的平均百分比显著高于年龄匹配的RES大鼠。结果表明，包括特定细菌中间普氏菌和具核梭杆菌在内的牙菌斑在导致体温升高方面可能发挥一定作用。
