Human recombinant gamma-interferon stimulates proliferation and inhibits collagen and fibronectin production by human dental pulp fibroblasts.

Human recombinant-gamma-interferon was tested on human dental pulp fibroblast activity in vitro. Fibroblast proliferation was estimated by a colorimetric test. Type I and type III collagens and fibronectin were quantified by radioimmunoassay in culture supernatant from confluent fibroblasts. A dose dependent stimulation of the proliferation was observed when fibroblasts were treated with recombinant-gamma-interferon. In contrast, an inhibition of the synthesis of soluble types I and III collagen and fibronectin by confluent cell cultures treated with recombinant-gamma-interferon occurred without apparent modification of the insoluble collagen level in the cell layer. Quantimetric analysis of type I collagen immunoperoxidase labelling have demonstrated that there was no intracellular storage of type I collagen in these cultured fibroblasts. These data support the view that human recombinant-gamma-interferon can affect human dental pulp fibroblast functions and thus may play an important part in the regulation of fibrosis.

Diagnostic procedures for evaluating pulpally involved teeth.

Pulpal and periapical problems are often difficult to diagnose because of seemingly conflicting or unclear symptoms. This difficulty increases when there is an emergency situation, and improper diagnosis can lead to improper treatment, causing distress to both the patient and clinician. Because the histopathologic condition of the pulp cannot be determined with clinical means or other diagnostic data, the clinician should focus on making an accurate clinical diagnosis using the patient's history and description of pain, clinical examination, and various diagnostic tests. This review discusses these factors and stresses the importance of making an accurate diagnosis.

Auricular electrical stimulation and dental pain threshold.

A modified double-blind evaluation of naloxone reversibility of dental analgesia produced by auricular electrical stimulation (AES) was examined in 40 subjects assigned randomly to one of four groups: AES followed by saline (AS), AES followed by naloxone (AN), placebo AES followed by saline (PS), and placebo AES followed by naloxone (PN). Dental pain threshold was tested using a hand-held dental pulp tester. A second investigator administered the true or placebo AES using an electrical stimulator. A third investigator injected intravenously saline or naloxone. The subjects and investigators 1 and 3 were blind to all treatment conditions. A repeated measures analysis of variance revealed a significant difference among the four groups. The AES groups exhibited a statistically significant 18% elevation of pain threshold, whereas the two placebo stimulation groups (PS and PN) remained essentially unchanged. The mean pain threshold increased to more than 23% for group AS, but fell to less than 12% for the subjects in group AN, who were given naloxone. These findings indicate a small but significant elevation of pain threshold by AES, an effect partially blocked by naloxone, suggesting an endogenous opioid system as one mechanism for AES analgesia.
