The Efficacy of a Chewing Gum Containing Phyllanthus emblica Fruit Extract in Improving Oral Health

Phyllanthus emblica fruit extract alleviates halitosis and reduces the inflammatory response to oral bacteria

OBJECTIVE

To assess the efficacy of Phyllanthus emblica extract in alleviating halitosis and reducing the inflammatory response to halitosis-related bacteria.

METHODOLOGY

This investigation, using Phyllanthus emblica fruit extract (PE), involved four aspects. First, we evaluated the effect on growth and aggregation of halitosis-related bacteria, including Fusobacterium nucleatum, Porphyromonas gingivalis, and Solobacterium moorei, using a microdilution assay and scanning electron microscopy. Second, volatile sulfur compound (VSC) levels were measured on individuals with halitosis in randomized short-term (26 participants) and double-blind randomized long-term trials (18 participants in each group) after rinsing with PE for 3, 6, and 12 h, and 28 days. Third, we analyzed pro-inflammatory cytokine expression in TR146 cells using quantitative real-time PCR and enzyme-linked immunosorbent assays. Lastly, we assessed pro-inflammatory cytokine secretion and Toll-like receptor (TLR) 2 mRNA expression via the same experimental methods in a three-dimensional oral mucosal epithelial model (3D OMEM).

RESULTS

PE extract dose-dependently inhibited the growth of F. nucleatum (50% inhibition concentration [IC50]=0.079%), P. gingivalis (IC50=0.65%), and S. moorei (IC50=0.07%) and effectively prevented bacterial aggregation. Furthermore, VSC contents decreased significantly at 3, 6, and 12 h after rinsing with 5% PE compared with those in the control. Long-term use of mouthwash containing 5% PE for 28 days led to a significant decrease in VSC contents. PE attenuated the F. nucleatum- or P. gingivalis-stimulated mRNA expression and protein release of interleukin (IL)-6 and IL-8 in TR146 cells. It also suppressed IL-8 and prostaglandin E2 secretion and TLR2 mRNA expression in F. nucleatum-induced OMEMs.

CONCLUSION

Our findings support the use of PE in oral care products to alleviate halitosis and it may reduce inflammation.

Phyllanthus emblica fruits: a polyphenol-rich fruit with potential benefits for oral management

The fruit of Phyllanthus emblica Linn., which mainly grows in tropical and subtropical regions, is well-known for its medicine and food homology properties. It has a distinctive flavor, great nutritional content, and potent antioxidant, anti-inflammatory, anti-cancer and immunoregulatory effects. According to an increasing amount of scientific and clinical evidence, this fruit shows significant potential for application and development in the field of oral health management. Through the supplementation of vitamins, superoxide dismutase (SOD) and other nutrients reduce virulence expression of various oral pathogens, prevent tissue and mucosal damage caused by oxidative stress, etc. Phyllanthus emblica fruit can promote saliva secretion, regulate the balance of the oral microecology, prevent and treat oral cancer early, promote alveolar bone remodeling and aid mucosal wound healing. Thus, it plays a specific role in the prevention and treatment of common oral disorders, producing surprising results. For instance, enhancing the effectiveness of scaling and root planing in the treatment of periodontitis, relieving mucosal inflammation caused by radiotherapy for oral cancer, and regulating the blood glucose metabolism to alleviate oral discomfort. Herein, we systematically review the latest research on the use of Phyllanthus emblica fruit in the management of oral health and examine the challenges and future research directions based on its chemical composition and characteristics.

"Medicine food homology" plants promote periodontal health: antimicrobial, anti-inflammatory, and inhibition of bone resorption

"Medicine food homology" (MFH) is a term with a lengthy history. It refers to the fact that a lot of traditional natural products have both culinary and therapeutic benefits. The antibacterial, anti-inflammatory and anticancer effects of MFH plants and their secondary metabolites have been confirmed by numerous research. A bacterially generated inflammatory illness with a complicated pathophysiology, periodontitis causes the loss of the teeth's supporting tissues. Several MFH plants have recently been shown to have the ability to prevent and treat periodontitis, which is exhibited by blocking the disease's pathogens and the virulence factors that go along with them, lowering the host's inflammatory reactions and halting the loss of alveolar bone. To give a theoretical foundation for the creation of functional foods, oral care products and adjuvant therapies, this review has especially explored the potential medicinal benefit of MFH plants and their secondary metabolites in the prevention and treatment of periodontitis.

Aqueous Extract of Emblica officinalis Linn (Indian gooseberry) in Combination with Iodine is More Efficacious than Iodine Alone in Mitigating Mucositis in Head and Neck Cancer Patients Undergoing Curative Radiotherapy: Retrospective Observations

Mucositis is a very painful unavoidable and common side effect in head and neck cancer patients undergoing curative radiotherapy and can affect the planned treatment. In this study, attempt is made at understanding the efficacy of Emblica officinalis Linn (amla) when combined with providone iodine in mitigating radiation-induced mucositis, weight loss and tumor control. This was a retrospective chart based study and was carried out by extracting the data from the files of patients with cancer of head and neck who used amla in combination with iodine or iodine alone during the course of the curative radiotherapy (> 60 Gy). The data was entered in to Microsoft excel and subjected to statistical analysis using SPSS 17 software. The results indicate that when compared with iodine alone, the group where iodine and amla gargling were used was very effective in delaying mucositis, reduced incidence of intolerable mucositis (P = 0.027), quantitative grade of weight loss (P = 0.016), incidence of severe weight loss (P = 0.03) without affecting tumor response. The results suggest that when compared with iodine alone, amla when combined with iodine was more effective in mitigating radiation mucositis and by not interfering with the tumor cell kill. As far as the authors are aware of this is the first study that shows the usefulness of combining iodine with Amla in mitigating radiation-induced mucositis.

Comparative Evaluation of Antibacterial Efficacy of Emblica Officinalis Lollipop Against Streptococcus Mutans Counts in Institutionalized Visually Impaired Children

Background

Among the 1.21 billion population of India, 26.8 million individuals have disabilities, and around five million are visually impaired. These children encounter problems related to oral health maintenance, thus further leading to dental problems. Even though Pediatric dentists treat visually impaired children for their oral problems, they emphasize mainly on the prevention of dental caries. Dental caries has a multifactorial etiology, and dentists are unable to find a complete solution for its prevention. However, reducing Streptococcus mutans has been seen to reduce the caries rate in the past. The use of the herbal product Emblica officinalis to reduce Streptococcus mutans levels has been documented. An affordable delivery system is required to use Emblica officinalis for its anticaries action. Thus, a unique delivery system of herbal sugar-free lollipops containing Emblica officinalis extract was made and can effectively deliver antimicrobial action in visually impaired children.

Aim

To evaluate the antibacterial efficacy of Emblica officinalis lollipop on Streptococcus mutans counts and pH levels in institutionalized visually impaired children.

Method

A total of 60 institutionalized visually impaired children (age: 4 to 14 years) were selected. The study consisted of two groups (experimental “Emblica officinalis lollipop” and control “placebo lollipop”), and the children were divided equally into both groups. Children from the study and control groups were subjected to the respective lollipops twice daily for seven days. Streptococcus mutans count and pH count were evaluated at baseline and after seven days post-intervention of the respective lollipop.

Results

The results showed that in both groups, Streptococcus mutans count was reduced post-intervention. However, the efficacy of the study group (Emblica officinalis lollipop) in inhibiting the Streptococcus mutans count was better than the control group (placebo lollipop). An increase in the pH level was seen post-intervention for both the study and control groups. And on the intergroup comparison, no statistical significance was found.

Conclusion

The use of Emblica officinalis lollipop is effective in inhibiting the Streptococcus mutans count when compared with the placebo lollipop. While marginal pH change was seen in both groups. Thus, the herbal modality most acceptable without any pharmaceutical concerns should be chosen. Emblica officinalis lollipops can be used in institutionalized visually impaired children to reduce the oral Streptococcus mutans count and maintain a healthy oral cavity.

Jawarish Shahi: A special dosage form of herbal formulations for functional gastrointestinal disorders in Unani medicine- A comprehensive review

ETHNOPHARMACOLOGICAL RELEVANCE

Functional gastrointestinal disorders (FGIDs) are the most common diagnoses in gastroenterology and represent a group of chronic unexplained gut syndromes. The best-known disorders are irritable bowel syndrome (IBS) and functional dyspepsia (FD). Jawarish Shahi (JS) is used for gastrointestinal disorders in Unani Medicine (UM).

AIMS OF THE STUDY

The present review aims to evaluate the FD and IBS in Unani medicine and scientific evidence for the safety and efficacy of JS and its herbal ingredients in the management of FD and IBS.

MATERIAL AND METHODS

Sources of data are from the classical literature of UM, Canon of medicine, Khazainul Advia, Indian Medicinal Plants-An Illustrated Dictionary. Databases, PubMed, Science Direct, Scopus, Google Scholar, were explored for related studies.

RESULTS

An updated review on the concept of FGIDs in Unani medicine, its pathophysiology, and management is presented. Comprehensive information on JS and its traditional and ethnopharmacological clinical attributes, standardization and toxicity study, biomedical studies of herbs in JS for their efficacies in FD and IBS are presented.

CONCLUSIONS

The outcome of the work clearly indicates that disease conditions similar to FD and IBS and their successful treatment are described in Unani Medicine. JS has been used for disease conditions similar to FD and IBS by the physicians of the medieval period. The herbs in JS are widely researched for pharmacologically active substances and were reported for antioxidant, immunomodulatory, gastroprotective, antispasmodic, analgesic, antidiarrheal, antisecretory, laxative, anti-inflammatory, anxiolytic, and antidepressant properties. Nevertheless, further explorations, particularly well-designed clinical trials are required for efficacy.

Analysis of Plant Origin Antibiotics against Oral Bacterial Infections Using In Vitro and In Silico Techniques and Characterization of Active Constituents

The pervasiveness of oral bacterial infections in diabetic patients is a serious health concern that may produce severe complications. We investigated 26 Ayurvedic medicinal plants traditionally used for treatment of the oral bacterial infections with the aim to look for new promising drug leads that can be further employed for herbal formulation design. The plants were grouped into three categories based on traditional usage. All plant extracts were examined for antibacterial, antibiofilm and antiquorum-sensing properties. The plants with significant activities including Juglans regia, Syzygium aromaticum, Eruca sativa, Myristica fragrans, Punica granatum and Azadirachta indica were further analyzed using HPLC-DAD-QToF and GC-MS. In silico and in vitro activity was evaluated for selected constituents. Finally, it could be concluded that eugenol and 2-phenylethylisothiocyanate are major contributors towards inhibition of bacterial biofilms and quorum sensing.

Effect of Lonicera caerulea var. emphyllocalyx Fruit on Biofilm Formed by Porphyromonas gingivalis

Porphyromonas gingivalis is an important pathogenic anaerobic bacterium that causes aspiration pneumonia. This bacterium frequently forms biofilms in the oral cavity and in respiratory tract-associated medical devices. Bacterial colonization that occurs in association with this biofilm formation is the main reason for incurable aspiration pneumonia. The Lonicera caerulea var. emphyllocalyx (LCE) fruit has been used in folk medicine in Hokkaido, the northern part of Japan. The aim of this study was to elucidate one of the antimicrobial mechanisms of LCE methanol extract (LCEE)-the inhibitory effect of LCEE on biofilm formation by P. gingivalis. Our results show that LCEE significantly reduced biofilm formation by three different P. gingivalis isolates in a concentration- and time-dependent manner that were quantified by the adsorption of safranin red. When LCEE was added to biofilms already formed by P. gingivalis, LCEE did not degrade the biofilm. However, treatment with LCEE significantly promoted the removal of existing biofilm by vibration compared to that of control. We also confirmed biofilm formation in LCEE-treated P. gingivalis in tracheal tubes using scanning electron microscopic (SEM) analysis. Cyanidin 3-O-glucoside (C3G), one of the components of LCE, also inhibited the formation of biofilm by P. gingivalis in a concentration-dependent manner. Our results reveal that LCEE may be an effective antibacterial substance for P. gingivalis-induced aspiration pneumonia because of its role in the suppression of bacterial biofilm formation in the oral cavity.
