[Clinical evaluation of gingival sulcus temperature in healthy subjects].
OBJECTIVE
To evaluate gingival sulcus temperature in healthy subjects.


METHODS
Small size, high sensitivity and rapid response thermocouple was used to measure the gingival sulcus temperature in seven dental students with healthy periodontium. 28 teeth in each subject were tested.


RESULTS
For an individual subject, the gingival sulcus temperatures in all sites were always lower than sublingual temperature. There was obviously increased temperature gradient from anterior teeth to posterior teeth. The mean gingival sulcus temperatures on buccal sites were lower than that on lingual sites. There was no significant difference between maxillary and mandibular corresponding sites on lingual side. However, mandibular temperature was significantly lower than maxillary temperature on buccal side. Mandibular buccal temperature was the lowest in all tooth surfaces.


CONCLUSIONS
Gingival sulcus temperature in subjects with healthy periodontium is easily influenced by environmental factors.
