Aim The aim of the present study is to evaluate the efficacy of curcumin gel as local drug delivery post-scaling and root planing and its effect on clinical parameters like plaque, gingival scores, pocket depth, and clinical attachment level (CAL). Materials and methods Ten patients with two sites in the contralateral quadrants having probing pocket depths (PPDs) of ≥5 mm were selected. Full-mouth scaling and root planing (SRP) was performed followed by the application of curcumin gel on a single side. Assessment of plaque index (PI), gingival index (GI), PPD, and CALs were done at the baseline and at the 4th week. Results The results revealed that there was a statistically significant reduction in PI and probing depth in the test group when compared with the control group. CAL was improved but the results were not statically significant. Conclusion The local application of curcumin gel when used in conjunction with SRP showed a significant improvement in periodontal parameters and has a beneficial effect in patients with chronic periodontitis. Clinical significance Curcumin gel as an adjunct to SRP showed a marked improvement in restoring gingival health by an improvement in clinical parameters. It has proven properties like anti-inflammatory, antioxidant, antimicrobial, hepatoprotective, immunostimulant, antiseptic, antimutagenic, and it also accelerates wound healing. It may be a more acceptable and viable option for the common man. Curcumin can be used as an effective alternative local drug delivery agent.

Background and Objectives Herbal dentifrices are fast gaining popularity in most parts of Asia and Europe. Although effects of dentifrices on pathogenic plaque microorganisms has been documented, little or no evidence exists with regard to their effects on the useful microflora, which help to keep the pathogenic strains at bay. The present study was attempted to evaluate and compare these effects of herbal and conventional dentifrice. Methods 60 student participants in the age group of 18 to 28 years with good oral hygiene (OHI score = 0) were randomly divided into two groups, test and control. The test group used herbal dentifrice and the control group, a regular dentifrice. Plaque and saliva samples were collected at baseline, immediately after brushing, 12 hours after brushing, at 1 week and at 1 month, and cultured. The Streptococcus mitis and Lactobacillus counts along with total microbial counts were estimated at the various time intervals. Results Day 1 showed no significant difference between test and control groups with regard to Streptococcus mitis and Lactobacillus counts as well as total CFU (P>0.05), but at one week control group showed significant increase in streptococcus count in plaque and saliva(P>0.01). Whereas, the test group showed significant increase in L. bacillus and total CFU count in saliva, 12 hrs after brushing, when evaluated at one month (p>0.01). Conclusion Herbal dentifrices may be slightly more effective in preservation of beneficial oral microflora when compared to regular dentifrices, although both are equally effective in inhibiting the pathogenic microorganisms.
