Sulcular temperatures were measured on 35 clinically stable and restored osseointegrated dental implants and compared to 50 remaining natural teeth in 9 partially-edentulous adults using the PerioTemp temperature probe (ABIO-DENT, Inc., Danvers, MA USA). Replicate peri-implant sulcular measurements showed a mean difference of 0.1 +/- 0.15 (SD) degrees C. Implant temperatures varied from 0.41 to 3.9 degrees C below sublingual temperatures measured on each patient, and maxillary implants were significantly cooler than mandibular implants (p < 0.001, t-test). A posterior-to-anterior temperature gradient was found in both the maxilla and mandible, with anterior implants significantly cooler than posterior fixtures. No significant differences were found in sulcular temperatures of osseointegrated dental implants and natural teeth located in anatomically-equivalent oral sites. Similarly to natural teeth, sulcular temperature may serve as a valuable diagnostic tool in evaluating dental implant status.

... Subgingival specimens were collected with paper points from periodontitis patients who each contributed samples from three hot and three cool premolar/molar pockets with a probing depth of 6-10 mm and bleeding on probing. Each periodontal sample originated from separate teeth and interproximal surfaces and was transported in VMGA III (Dahlén et al., 1993) (Rams et al., 1993b), and TSBV agar for Aggregatibacter actinomycetemcomitans (Slots, 1982). Porphyromonas gingivalis, Tannerella forsythia, Campylobacter species, Fusobacterium nucleatum, Parvimonas micra, Prevotella intermedia/nigrescens, and A. actinomycetemcomitans were routinely identified using established methods Rams et al., 1996Rams et al., , 2016Rams et al., , 2018b, and the percentage of each study species was calculated. ...
