Non-steroidal Anti-inflammatory Poisoning | Drug: cataflam (diclofenac potassium) Drug: placebo | Phase 2 |
Study Design This study utilized a randomized, controlled, double-blind, parallel-group design to investigate the 6-month effect of a cyclic regimen of diclofenac potassium [50 mg, twice daily (b.i.d)] on clinical parameters of periodontal disease and levels of PGE2 and IL-1beta in GCF. After clinical and radiographic examination, subjects were divided into two groups: 28 patients in the test group and 13 patients in the control group. Of the 28 patients in the test group, ten (nine men, one woman) were smokers, eleven (six women, five men) were non-smokers, and seven (all men) were ex-smokers. Thirteen patients in the control group comprised six smokers (five men, one woman), five non-smokers (four women, one man) and two ex-smokers (both men).
Test and control groups were administered either diclofenac potassium (50 mg) or placebo gel caps (containing inactive filler of starch flour and carboxymethylcellulose), respectively, b.i.d. after a meal for 6 months in a cyclic regimen. Administration of diclofenac potassium or placebo was undertaken from baseline to 2 months, no drug (diclofenac potassium or placebo) was administered from 2 to 4 months, then diclofenac potassium or placebo therapy was reinstituted (b.i.d.) from 4 to 6 months. To promote compliance, each patient was recalled monthly. Patients in both groups were instructed on oral hygiene, including tooth brushing for at least 2 minutes (b.i.d.) and daily interdental cleaning. SRP was not carried out during these recalls. During the screening period (baseline as well as 2, 4 and 6 months), all subjects underwent physical examinations and biochemical analyses (blood chemistry, complete blood count, urinalyses and pregnancy testing).

Active Comparator: placebo
or placebo gel caps (containing inactive filler of starch flour and carboxymethylcellulose) b.i.d. after a meal for 6 months in a cyclic regimen. Administration of placebo was undertaken from baseline to 2 months, no drug (placebo) was administered from 2 to 4 months, then diclofenac potassium therapy was reinstituted (b.i.d.) from 4 to 6 months.

- Changes in gingival crevicular fluid levels of prostaglandin E2 by 50 mg diclofenac potassium administration [ Time Frame: Baseline, 2 months, 4 months and 6 months ]Administration of diclofenac potassium or placebo was undertaken from baseline to 2 months, no drug (diclofenac potassium or placebo) was administered from 2 to 4 months, then diclofenac potassium or placebo therapy was reinstituted (b.i.d.) from 4 to 6 months. Gingival crevicular fluid levels of prostaglandin E2 was measured by using ELISA method, at baseline, 2-month, 4-month and 6-month of the study period.
- Changes in gingival crevicular fluid levels of interleukin-1beta by 50 mg diclofenac potassium administration [ Time Frame: Baseline, 2 months, 4 months and 6 months ]administration of diclofenac potassium or placebo was undertaken from baseline to 2 months, no drug (diclofenac potassium or placebo) was administered from 2 to 4 months, then diclofenac potassium or placebo therapy was reinstituted (b.i.d.) from 4 to 6 months. Gingival crevicular fluid levels of interleukin-1beta were measured by using ELISA method, at baseline, 2-month, 4-month and 6-month of the study period.
- Changes in plaque index (PI) by 50 mg diclofenac potassium administration [ Time Frame: Baseline, 2 months, 4 months and 6 months ]At baseline, 2-, 4- and 6-month, plaque index (PI) were recorded. Plaque index (PI); 0: no visible plaque, 1: minor plaque accumulation during probing, 2: visible plaque near by gingiva, 3: full plaque accumulation of the tooth.
- Changes in gingival index (GI) by 50 mg diclofenac potassium administration [ Time Frame: Baseline, 2 months, 4 months and 6 months ]At baseline, 2-, 4- and 6-month, gingival index (GI) were recorded. Gingival index (GI); 0: healthy gingiva, 1: slightly inflammation and no bleeding on probing, 2: moderate gingival inflammation and bleeding on probing, 3: spontaneous bleeding and/or suppuration.
- Changes in probing depth (PD) by 50 mg diclofenac potassium administration [ Time Frame: Baseline, 2 months, 4 months and 6 months ]At baseline, 2-, 4- and 6-month, probing depth (PD) were recorded. Probing depth (PD): with William's periodontal probe, distance between gingival margin to bottom of the sulcus).
- Changes in probing clinical attachment level by 50 mg diclofenac potassium administration [ Time Frame: Baseline, 2 months, 4 months and 6 months ]At baseline, 2-, 4- and 6-month, clinical attachment level (CAL) were recorded. Clinical attachment level (CAL); with William's periodontal probe, distance between enamel-cement junction to bottom of the sulcus).
