| ABSTRACTBackground: In periodontics, there is a need for objective measurements in monitoring disease processes& inassessing the effectiveness of treatment. Elevated temperature is one of 4 cardinal inflammatory signs& is a potentialindicator of periodontal disease. The purpose of this study was to determine& compare the severity of periodontaldisease by subgingival temperature measurements in health& disease state, determine the correlation betweenperiodontal parameters (bleeding on probing& probing depth) and subgingival temperature measurements&compare gingival crevicular fluid (GCF) flow with subgingival temperature.Material & Methods: 10 male subjects ranging in age (35-55) years were measured at 4 sites per tooth for subgingivaltemperature, GCF flow, probing pocket depth& bleeding on probing.GCF collected by means of endodontic paperpoints size 30. Subgingival temperatures were measured using digital thermometer while sublingual temperature wasmeasured by sublingual digital thermometer. To compensate for subject-to-subject variations in core temperature,site temperatures were measured& expressed as a difference relative to sublingual temperature. Followingmeasurement of subgingival temperature, probing depth& bleeding on probing were recorded using periodontalprobe.Results: The results indicated that subjects differed in their mean temperature difference. Similarly, temperature at asite in relation to its location in the mouth, pocket depth, bleeding on probing, GCF flow& inflammatory status.Analysis of the results revealed a significant (p<0.05) difference between mean temperature difference of healthy&diseased sites, anterior& posterior, maxillary& mandibular teeth for both healthy& diseased sites. A natural posterior toanterior temperature gradient was observed with the posterior sites being hotter than the anterior sites& mandibularsites hotter than maxillary sites. Tooth by tooth analysis showed that diseased teeth have higher temperature thananatomically equivalent healthy teeth. Subgingival temperature also correlates significantly (p<0.05) with certainclinical parameters like probing depth, bleeding on probing while GCF flow differed significantly from subgingivaltemperature.Conclusion: subgingival temperature measurements can be used as a successful mean of diagnosis or monitoringperiodontal condition, but additional studies are necessary to develop thermometry as a diagnostic aid inperiodontal practice.Key words: Subgingival temperature, periodontal disease severity.
