The Antiplaque Efficacy of Two Herbal-Based Toothpastes: A Clinical Intervention

Green Alternatives as Antimicrobial Agents in Mitigating Periodontal Diseases: A Narrative Review

Periodontal diseases and dental caries are the most common infectious oral diseases impacting oral health globally. Oral cavity health is crucial for enhancing life quality since it serves as the entranceway to general health. The oral microbiome and oral infectious diseases are strongly correlated. Gram-negative anaerobic bacteria have been associated with periodontal diseases. Due to the shortcomings of several antimicrobial medications frequently applied in dentistry, the lack of resources in developing countries, the prevalence of oral inflammatory conditions, and the rise in bacterial antibiotic resistance, there is a need for reliable, efficient, and affordable alternative solutions for the prevention and treatment of periodontal diseases. Several accessible chemical agents can alter the oral microbiota, although these substances also have unfavorable symptoms such as vomiting, diarrhea, and tooth discoloration. Natural phytochemicals generated from plants that have historically been used as medicines are categorized as prospective alternatives due to the ongoing quest for substitute products. This review concentrated on phytochemicals or herbal extracts that impact periodontal diseases by decreasing the formation of dental biofilms and plaques, preventing the proliferation of oral pathogens, and inhibiting bacterial adhesion to surfaces. Investigations examining the effectiveness and safety of plant-based medicines have also been presented, including those conducted over the past decade.

Evaluation of Anti-plaque and Anti-gingivitis Efficacy of Two Commercially Available Herbal and Non-herbal Toothpastes

BACKGROUND

 Plaque-associated oral disease affects a considerable portion of the population and is considered one of the major causes of tooth loss. The presence of plaque may be the reason for dental caries, gingivitis, periodontal problems, and halitosis. Many mechanical aids are used to control plaque, including toothbrushes, dental floss, mouth rinses, and dentifrices, and the most effective method of controlling gingivitis is supragingival plaque control.

AIM AND OBJECTIVE

To evaluate and compare the anti-plaque and anti-gingivitis efficacy of commercially available herbal toothpaste (Meswak) and non-herbal toothpaste (Pepsodent).

MATERIALS AND METHOD

50 subjects aged between 10 and 15 years with a full complement of dentition were included in the study. The two toothpastes were provided to the subjects in plain white tubes by the investigator. Subjects were instructed to brush their teeth twice daily using the given toothpaste for 21 days. Plaque and gingival scores on days 0, 7, and 21 were recorded, and the data were subjected to statistical analysis.

RESULT

At the end of the 21-day study, there was a statistically significant difference between the groups for plaque and gingival scores.

CONCLUSION

The plaque and gingival scores were significantly reduced throughout the study in both groups. In comparison, the herbal dentifrices show more effectiveness in reducing plaque and gingival scores, but no statistically significant difference was seen between the two groups.

Effect of a Novel Betel Leaf Dentifrice on Commonly Seen Oral Hygiene Parameters-A Randomized Clinical Crossover Study

The use of herbal medicine in dentistry has grown exponentially over time. Currently, herbal medicine is considered an effective oral hygiene aid. The objective of the current study is to assess the anti-plaque efficiency and reduction of gingival bleeding of betel leaf and miswak (Salvadora persica) toothpaste. This randomized clinical cross-over pilot study enrolled 60 individuals with mild gingivitis. They were segregated into two groups by drawing lots. The study lasted 20 days and included a two-week washout period between miswak and betel leaf toothpaste. The gingival and plaque index were measured at specific time intervals during the research period. The results revealed that betel leaf and miswak herbal toothpaste significantly decreased plaque index. Nevertheless, betel leaf toothpaste caused a more significant reduction in gingival bleeding scores (p < 0.001) when compared to miswak (p = 0.007). No significant decrease in gingival and plaque index was seen when subjects were asked to return to their conventional chemical toothpaste. The current study concluded that betel leaf toothpaste displayed a more substantial decrease in gingival bleeding when compared to miswak toothpaste. Additionally, more studies should be done on the therapeutic benefits of betel leaf toothpaste.

Effectiveness of Oil-Based Denture Dentifrices-Organoleptic Characteristics, Physicochemical Properties and Antimicrobial Action

Denture dentifrices must be effective and not deleterious to prosthetic devices. This study formulated and evaluated dentifrices based on oils of Copaifera officinalis, Eucalyptus citriodora, Melaleuca alternifolia, Pinus strobus, and Ricinus communis. Organoleptic characteristics (appearance, color, odor, taste), physicochemical properties (pH, density, consistency, rheological, abrasiveness, weight loss, and surface roughness) and antimicrobial (Hole-Plate Diffusion–HPD)/anti-biofilm (Colony Forming Units–CFU) action against Staphylococcus aureus, Streptococcus mutans, and Candida albicans were evaluated. Formulations were compared with water (negative control) and a commercial dentifrice (positive control). The data were analyzed by Kruskal-Wallis and Dunn tests (α = 0.05). The organoleptic and physicochemical properties were adequate. All dentifrices promoted weight losses, with high values for C. officinalis and R. communis, and an increase in surface roughness, without differing from each other. For antimicrobial action, C. officinalis and E. citriodora dentifrices were similar to positive control showing effectiveness against S. mutans and C. albicans and no dentifrice was effective against S. aureus; regarding the anti-biofilm action, the dentifrices were not effective, showing higher CFU counts than positive control for all microorganisms. The dentifrices presented satisfactory properties; and, although they showed antimicrobial action when evaluated by HPD, they showed no effective anti-biofilm action on multispecies biofilm.

Salvadora persica: Nature's Gift for Periodontal Health

Salvadora persica (SP) extract, displays very valuable biotherapeutic capacities such as antimicrobial, antioxidant, antiparasitic and anti-inflammatory effects. Numerous investigations have studied the pharmacologic actions of SP in oral disease therapies but its promising outcomes in periodontal health and treatment are not yet entirely described. The current study has been planned to analyze the reported effects of SP as a support to periodontal therapy to indorse regeneration and healing. In consort with clinical trials, in vitro investigations show the advantageous outcomes of SP adjunctive to periodontal treatment. Yet, comprehensive supplementary preclinical and clinical investigations at molecular and cellular levels are indispensable to reveal the exact therapeutic mechanisms of SP and its elements for periodontal health and therapy.

Miswak and oral health: An evidence-based review

Poor oral health has been associated with several chronic and systemic disease. Currently, the most common method of teeth cleaning is the use of a toothbrush together with dentifrices. However, natural chewing stick such as S. persica miswak is still used in many developing countries due to their low cost and availability. The present review aims to summarize the evidences on effectiveness of miswak in promoting oral health. The search was performed using Medline via Ebscohost, Scopus and Google Scholar database to obtain relevant articles published between 2010 to May 2020 using the following set of keywords 1) Miswak OR Salvadora OR persica AND 2) dental OR caries OR plaque OR oral OR orthodontics. Isolated microbial inhibition studies were excluded from the review due to its well-established wealth of literature. Miswak was administered as ten different forms, namely mouthwash, toothpaste, chewing stick, essential oil, aqueous extract, ethanol extract, probiotic spray, dental varnish, dental cement or chewing gum. All studies reported a positive effect of miswak as an anti-plaque, anti-gingivitis, anti-cariogenic, promotion of gingival wound healing, whitening properties, orthodontic chain preservation, and biocompatibility with oral cells. Miswak in its different forms demonstrated positive effect towards oral health maintenance and management.
