Comparative Evaluation of Antiplaque Efficacy between Essential Oils with Alcohol-Based and Chlorhexidine with Nonalcohol-Based Mouthrinses

Revisiting Oral Antiseptics, Microorganism Targets and Effectiveness

A good oral health status is mostly dependent on good oral hygiene habits, which knowingly impacts systemic health. Although controversial, chemical oral antiseptics can be useful in adjunct use to mechanical dental plaque control techniques in the prevention and management of local and overall health and well-being. This review aims to revisit, gather and update evidence-based clinical indications for the use of the most popular oral antiseptics, considering different types, microorganism targets and effectiveness in order to establish updated clinical recommendations.

Formulation, development, and evaluation of anti-inflammatory and antimicrobial effects of a novel polyherbal mouthwash-An in vitro study

AIM

The aim of this study was to prepare a polyherbal mouthwash and evaluate its antimicrobial and anti-inflammatory efficacy against commercially available herbal mouthwash. The objective was to signify whether the novel herbal combination (extracts of Zingiber officinale [ginger], Curcuma longa [turmeric], and Syzygium aromaticum [clove] 5% v/w) could be a better alternative to commercially available herbal mouthwashes.

MATERIALS AND METHODS

An in vitro study was undertaken in which extracts of Z. officinale (ginger), C. longa (turmeric), and S. aromaticum (clove) 5% v/w were used. Seven different concentrations were prepared and tested against Streptococcus mutans, Enterococcus faecalis, Candida albicans, and Staphylococcus aureus in Mueller-Hinton agar medium. Plates were incubated aerobically at 37° C for 48 h, and the zone of inhibition was measured using a vernier caliper. Commercially available herbal mouthwash (Hiora) was used as a control group. The data were analyzed by descriptive analytics.

RESULTS

Results showed that the efficacy of novel polyherbal mouthwash had comparatively less significant antimicrobial properties against the microorganisms as compared to the commercially available herbal mouthwash. The minimum inhibitory concentration was also found to be very high, that is, 100 μg/mL.

CONCLUSION

There was no significant antimicrobial and anti-inflammatory effects for the polyherbal mouthwash as compared to commercially available herbal mouthwash (Hiora). Because this combination is readily available, it can be a cost-effective alternative to commercially available herbal mouthwashes.

Effectiveness of tea tree oil versus chlorhexidine in the treatment of periodontal diseases: a systematic review

Background Plaque biofilm that adheres to tooth surfaces and gingiva is the main aetiology of periodontitis. Chlorhexidine (CHX) is considered as a gold standard anti-plaque and anti-gingivitis agent but it has side effects such as permanent staining of teeth and dysgeusia. Tea tree oil (TTO) is an essential oil extracted from the leaves of Melaleuca alternifolia. Many studies have reported that TTO exerts strong antibacterial, antifungal, antiviral and anti-inflammatory activities.Primary study objective The review aims to answer the question of whether TTO (intervention) is a viable alternative to CHX (comparator) for the management of gingival and periodontal disease (outcomes) in adolescents and adults (population).Methods/design The following search terms were used in PubMed, Scopus, Proquest, Web of Science, EBSCO (dentistry and open access), Cochrane database, Clinical.gov.org and ctri.nic.in to search for relevant articles: patients with periodontal disease; OR periodontitis; OR gingivitis; OR gingival inflammation; AND essential oil; OR tea tree oil; OR Melaleuca alternifolia; AND chlorhexidine; AND reduction in gingival index; OR reduction in plaque index; OR reduction in bleeding from gums. The initial check for the title and abstract screening followed by removal of duplicates in Mendeley Reference Manager (version 1.19.4) based on the inclusion and exclusion criteria were performed.Primary outcome measures Parameters such as plaque index (PI), plaque surface score, gingival index (GI), bleeding index or bleeding as measured by % of sites with bleeding on probing (BOP) or bleeding scores, papillary bleeding index (PBI), were the primary outcomes considered.Results TTO is found to be superior to CHX in reducing signs of gingival inflammation; however, CHX is superior to TTO in inhibiting plaque formation, probably due to its increased substantivity.Conclusion TTO may be used as an alternative to CHX for reduction of gingival inflammation in conjunction with efficient plaque control measures.

Salivary arginase activity after mechanical-chemical therapy

Abstract Introduction Salivary components can be used as biomarkers for diagnosing and monitoring oral diseases. There is evidence that one potential biomarker, arginase, is associated with the inflammatory processes of periodontal disease, and its enzymatic activity is reduced according to the improvement in the clinical parameters after treatment. Objective The present study aimed to evaluate the salivary arginase activity in gingivitis and periodontitis patients treated with full-mouth mechanical procedures combined with the adjunctive use of essential oils or chlorhexidine mouthwash, respectively. Material and method Twenty-six gingivitis and 16 periodontitis patients received complete periodontal examinations at the baseline and 3 months after therapy, in which the periodontal probing depth, clinical attachment loss, plaque index, and gingival index measurements were taken. At these same appointments, the salivary total protein level and salivary arginase activity were also established via spectrophotometry. Result There were improvements in all of the clinical parameters (p < 0.05) evaluated from the baseline to 3 months in both groups. In addition, the salivary arginase activity and total protein levels were reduced after the gingivitis treatment. Conclusion Similar to the clinical results, both therapeutic protocols positively affected the salivary arginase activity; however, further studies are necessary to clarify its potential as a salivary biomarker for periodontal monitoring.

A Novel Herbal Formulation versus Chlorhexidine Mouthwash in Efficacy against Oral Microflora

Aims and Objectives:

The aim of the study was to compare and to analyze the antimicrobial efficacy of 0.12% chlorhexidine and new formulated herbal mouthwash after using for 14 days. The objective was to signify whether the noval herbal combination could be a better alternative mouthwash to Chlorhexidine (CHX).

Materials and Methods:

This is a double-blinded, random controlled research study conducted in the Department of Oral Pathology and Microbiology. A total of 200 dental students were selected randomly, comprising of two groups, 100 in each, aged between 18 and 22 years with gingival index of score II. The first group was advised to oral rinse with 0.12% chlorhexidine mouthwash and the second group with new formulated herbal mouthwash for 14 days. Saliva samples were collected on the day 0 (baseline), followed by day 7 and 14 and microbial colony count was performed. The data obtained was statistically analyzed using SPSS version 16. Student's t-test was applied for comparison of the mean microbial count between the two groups. Repeated measures analysis of variance followed by Tukey's post hoc test was applied to assess the changes from day 0 to day 7 to day 14. The statistical significance level was set at P < 0.05.

Results:

Microbial colonies were reduced better in chlorhexidine group on the day 7 whereas, on day 14, greater reduction was observed in the herbal group in both gender groups with high statistical significance (P < 0.001).

Conclusions:

Herbal mouthwash formulation performed effectively well on long-term usage, could be used as an alternative mouthwash to overcome the disadvantages of chlorhexidine.
