Objective: To test the effectiveness of a dentifrice containing the turmeric and licorice extract compared to a control for preventing plaque and gingivitis over a four-month period., Material and Methods: Ninety (non-dental) participants with moderate gingival inflammation (≥ 40%) were selected. The triple blind study consisted of two phases, namely at first a 3-week pre-experimental phase of using an oxygenating and chlorhexidine (CHX) mouthrinse. Secondly, a 4-month experimental period in which participants were randomly assigned to a test or control group. All were instructed to brush their teeth twice daily for 2 minutes with their assigned dentifrice. Gingival bleeding (BI), plaque (PI) and gingivitis (GI) were assessed., Results: Eighty participants completed the protocol. At the first assessment in the pre-experimental phase, the mean scores of all indices showed no differences for the two groups. At the second session, the values of all three parameters had decreased significantly (p < 0.001). At the last session, the BI values were 0.52(0.25) for the test group and 0.56(0.25) for the control, the mean GI was 0.27(0.17) for the test group and 0.31(0.16) for the control, and for PI the scores were 1.89(0.46) for the test group and 1.98(0.43) for the control group. Statistical comparison of the scores for the two groups at each stage of the study showed no significant difference for any of the parameters., Conclusion: Within the limits of the current study design, dentifrice formulation and concentration of turmeric/licorice extracts, the results show that the adjuvant effect of the natural ingredients in the test dentifrice was not evident on clinical parameters of gingivitis and plaque., (© 2021 The Authors.

Background: Rinsing with the combined use of an oxygenating-agent (OA) and chlorhexidine (CHX) in addition to mechanical oral hygiene could improve and/or maintain good gingival health over a long period., Methods: This study had an examiner-blinded, randomized, six-group parallel design consisting of two-phases: a 3-week treatment phase and a subsequent 12-month experimental phase. A total of 267 subjects in good general health (≥18 years), without periodontitis, with at least five teeth per quadrant, and with moderate to advanced gingivitis were enrolled. A 3-week treatment phase was initiated to improve gingival health. Subjects were assigned to one of the six groups: two basic oral hygiene groups (Control I & II), one professional oral hygiene instruction group (OHI), one professional prophylaxis group (PP), an OA&CHX rinse group and a group receiving a combination of all regimens (COMBI group), being OHI + PP + OA&CHX. Dental plaque, gingival bleeding and staining assessments were performed at the start of the treatment phase, at baseline and at 4, 7, 10, and 12 months., Results: There was a significant reduction in dental plaque-scores for the OA&CHX and COMBI-group (0.51 [SD = 0.37], 0.38 [SD = 0.33] respectively) and a significant reduction in gingivitis scores for the OA&CHX and COMBI group (6.9% [SD = 14.0], 13.4% [SD = 13.4] respectively) from the start of the treatment phase to baseline. No clinically relevant changes were observed for the other four groups. After baseline, bleeding and plaque-scores increased back to a non-significant level between groups, and this level remained throughout the study., Conclusion: OA&CHX and COMBI-group showed a clinically relevant improvement after the treatment phase in terms of dental plaque and gingival bleeding levels. At the 4-month clinical assessment, there was no longer a significant difference between groups., (© 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objectives: The purpose of the study was to evaluate the effect on dental plaque and gingivitis of a dentifrice without sodium lauryl sulphate (SLS) compared to two SLS-containing dentifrices., Material and Methods: For this double-blind, parallel study, 90 volunteers having moderate gingival inflammation (≥40%) were randomly divided among three groups: one group using non-SLS dentifrice containing enzymes, colostrum and low concentrations of zinc and two control groups each using different SLS-containing dentifrices. Dental plaque scores (Turesky modification of Quigley & Hein) and gingivitis scores (Bleeding On Marginal Probing) were assessed at baseline, after 2 and 4 weeks., Results: Eighty-nine participants provided evaluable data. A slight decrease in gingivitis scores was observed for all groups over 4 weeks, which was statistically significant for the non-SLS group. Mean values for dental plaque scores did not show major differences over 4 weeks. For both parameters, no significant differences between groups could be observed at any time point. Patient appreciation was in favour of the SLS groups especially regarding the foaming effect., Conclusion: No significant differences could be observed with respect to the effect on plaque and gingivitis between SLS-containing and SLS-free dentifrice containing enzymes, colostrum and low concentration zinc. Patients enjoyed the duration of taste and the 'foaming effect' of SLS-containing dentifrices better., (© 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)
