Impact of the uninstructed use of a herbal, ayurvedic toothpaste on parameters of gingival health in periodontal aftercare patients: A randomized, double-blinded, two-arm parallel-group study.

AIM: The aim of this study was to evaluate the impact of the uninstructed use of a toothpaste containing herbal ayurvedic ingredients on parameters of gingival health in a cohort of periodontal aftercare patients affected by gingival inflammation compared to the use of a standard, non-herbal toothpaste. MATERIALS AND METHODS: The monocentric, randomized, double-blinded, two-arm parallel-group intervention was performed in a cohort of 88 periodontal aftercare patients with clinical signs of gingival inflammation. At baseline, bleeding on probing (BoP), gingival index (GI) and Quigley-Hein plaque index (QHI) were recorded. Subsequently, the study patients were randomly provided with a herbal ayurvedic toothpaste (n = 44) or a conventional, non-ayurvedic control toothpaste (n = 44) and without additional oral hygiene training instructed to use it 2× daily for the next 28 days. On day 28, BoP, GI and QHI were recorded again. RESULTS: At baseline, there were no significant differences between both groups. On day 28, mean GI and BoP scores were significantly lower (p < 0.001) compared to baseline in both groups. Differences between the groups could not be verified. Mean QHI scores did not change significantly between day 0 and day 28 in both groups. CONCLUSIONS: The impact of uninstructed toothbrushing with an ayurvedic toothpaste on the manifestation of gingival inflammation in periodontal aftercare patients is not significantly different to the use of a conventional, non-herbal toothpaste.

Impact of a Specific Collagen Peptide Food Supplement on Periodontal Inflammation in Aftercare Patients-A Randomised Controlled Trial.

Background: This controlled clinical trial evaluated the impact of a specific collagen peptide food supplement on parameters of periodontal inflammation in aftercare patients. Methods: A total of 39 study patients were enrolled. At baseline, bleeding on probing (BoP; primary outcome), gingival index (GI), plaque control record (PCR), recession (REC) and probing pocket depth (PPD) for the calculation of the periodontal inflamed surface area (PISA) were documented. After subsequent professional mechanical plaque removal (PMPR), participants were randomly provided with a supply of sachets containing either a specific collagen peptide preparation (test group; n = 20) or a placebo (placebo group; n = 19) to be consumed dissolved in liquid once daily until reevaluation at day 90. Results: PMPR supplemented with the consumption of the specific collagen peptides resulted in a significantly lower mean percentage of persisting BoP-positive sites than PMPR plus placebo (test: 10.4% baseline vs. 3.0% reevaluation; placebo: 14.2% baseline vs. 9.4% reevaluation; effect size: 0.86). Mean PISA and GI values were also reduced compared to baseline, with a significant difference in favor of the test group (PISA test: 170.6 mm2 baseline vs. 53.7 mm2 reevaluation; PISA placebo: 229.4 mm2 baseline vs. 184.3 mm2 reevaluation; GI test: 0.5 baseline vs. 0.1 reevaluation; GI placebo: 0.4 baseline vs. 0.3 reevaluation). PCR was also significantly decreased in both experimental groups at revaluation, but the difference between the groups did not reach the level of significance. Conclusions: The supplementary intake of specific collagen peptides may further enhance the anti-inflammatory effect of PMPR in periodontal recall patients.

Impact of a two-stage subgingival instrumentation scheme involving air polishing on attachment gain after active periodontal therapy.

BACKGROUND: The aim of this study was to evaluate whether clinical attachment level gain (ΔCAL) in deep untreated periodontal lesions may be improved by a two-stage, subgingival instrumentation scheme involving air polishing. METHODS: This 6-month, randomized, controlled, examiner-masked clinical trial was performed in 44 patients with periodontitis with untreated periodontal lesions ≥6 mm. At baseline, day 28, 84, and 168 CAL, probing depth (PD), bleeding on probing (BOP), and plaque control record (PlaCR) were recorded. After baseline examination control group patients received full-mouth sub- and supragingival instrumentation using scalers and curets. In the test group initial subgingival cleaning was limited to the removal of soft bacterial deposits by air polishing. Subgingival scaling and root planing was performed only after the first re-evaluation at day 28. RESULTS: In deep lesions ≥6 mm a significant reduction of mean CAL scores was observed at day 28 and at day 168 for both experimental groups. Differences between the groups however did not reach the level of significance. Mean PD was also significantly reduced at day 28 and at 168 in both experimental groups, with no significant differences between the groups. Mean BOP scores did not change significantly in both groups during the 168-day observation period. Only in the test group mean PlaCR scores were significantly reduced at day 168 compared with baseline. CONCLUSIONS: Subgingival instrumentation of untreated PD ≥6 mm by air polishing alone results in a significant short-term gain of CAL comparable to conventional scaling and root planing. Its sequential two-step combination with scaling and root planing, however, does not additionally enhance long-term gain of CAL.
