[Effect of periodontal initial therapy together with Chinese herbal compound for clearing heat and detoxification on interleukin-1 beta and tumor necrosis factor-alpha in gingival crevicular fluid of patients with chronic periodontitis].
OBJECTIVE
To observe the effect of periodontal initial therapy together with Chinese herbal compound for clearing heat and detoxification (Abbr. TCM) on the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta) in gingival crevicular fluid (GCF) of patients with chronic periodontitis (CPD).


METHODS
Thirty-four teeth of 24 patients with CPD were randomly assigned to the control group (17 teeth of 11 patients) and the treated group (17 teeth of 13 patients), they were treated for 8 weeks with periodontal initial therapy, but TCM was given additionally to the treated group. The GCF of the observed teeth was collected at the time before initial therapy (datum line) and at 2 and 8 weeks after treatment. At the same time, the clinical parameters, including probing depth (PD), clinical attachment loss (CAL), and bleeding on probing (BOP) were recorded, and the levels of TNF-alpha and IL-1 beta in GCF were measured by radioimmunoassay.


RESULTS
The levels of TNF-alpha and IL-1 beta in GCF after treatment were significantly lowered in all patients as compared with those before treatment (P<0.01), while PD, CAL and BOP showed significant reduction (P<0.01). After treatment, TNF-alpha and IL-1 beta levels in the treated group were lower than those in the control group (TNF-alpha: 2.5551 +/- 1.0157 microg/L vs 3.4341 +/- 1.0762 microg/L, IL-1 beta: 0.1335 +/- 0.0216 microg/L vs 0.1471 +/- 0.0169 microg/L; P<0.05).


CONCLUSIONS
TCM could enhance the effect of periodontal initial therapy in lowering TNF-alpha and IL-1 beta levels, which was attributed to reducing the inflammatory reaction of periodontal tissues.
