Lycium barbarum commonly known as goji berry, Chinese berry or Tibetian berry, is emerging as a popular superfood with anti-inflammatory and antioxidant properties. Goji berry is being used for the treatment of various cancers such as gastrointestional disorders, stroke, diabetes, Alzheimers disease, and glaucoma. However, its use for management of oral inflammatory diseases has not been explored. Therefore, the present study aims to evaluate the antimicrobial, anti-adhesion, and anti-biofilm, and cytotoxic properties of an ethanolic extract of Lycium barbarum (LBE) against oral and periodontal pathogens. The antimicrobial properties of LBE against five microorganisms were tested and compared against Chlorhexidine and doxycycline along with cytotoxicity and cell viability on the gingival fibroblast and modified keratinocyte cell lines. The anti-adhesion and anti-biofilm properties of LBE against Porphyromonas gingivalis, at its minimal bactericidal value, were evaluated. The antimicrobial, anti-adhesion and antibiofilm properties of LBE were found to be comparable to chlorhexidine but less than that of doxycycline. The LBE extract was also compactible to gingival fibroblast tissues and oral keratinocytes at 1 mg/ml. The results proved that goji berry is as effective as chlorhexidine and can be used as a promising natural herb for the management of inflammatory diseases of oral cavity.
A BSTRACT Objectives: The objective of this study was to determine the effect of suture-less anterior releasing incisions on postoperative wound healing following surgical removal of impacted mandibular third molars. Materials and Methods: A total of 112 patients were included in the study. Group 1 had 56 patients in which the anterior releasing incision was not sutured postoperatively, and group 2 had 56 patients, in whom the anterior releasing incision was sutured. The two groups were compared in terms of pain, swelling, and trismus at 1 day, 3 days, and 7 days postoperatively. The Univariate Type III Repeated-Measures ANOVA Assuming Sphericity was used to compare the two modes of treatments at different time points. The periodontal healing distal to the second molar was assessed on the first day and at 2 months following the surgical intervention. The independent t test was used to compare the periodontal healing between the two groups at two time points. Results: No significant difference was observed between the two groups for pain and trismus ( P > 0.05). However, the swelling was significantly greater in group 2 as compared to group 1 ( P < 0.001). Periodontal healing was better in group 2, which showed lower periodontal probing depth distal to the mandibular second molar, compared to group 1 ( P < 0.05). Conclusion: Suture-less anterior releasing incision decreases the postoperative swelling and edema, but the periodontal healing was poor when compared to the sutured anterior releasing incision cases. The type of closure technique did not have any significant influence on pain and trismus.
Background: Lycium barbarum (L. barbarum), popularly referred to as Goji berry, is a promising herb known for its powerful anti-antioxidant, antibacterial, and anti-inflammatory properties. It is used in traditional Chinese medicine for treating inflammatory and infectious diseases. It has also shown good anti-cancer properties and has been tested against liver, colon, prostate, breast, and cervical cancers. However, no study has yet evaluated the role of goji berries against oral cancer. Hence, the present paper aims to evaluate the anticancer properties of L. barbarum against oral squamous cell carcinoma. Method: Ethanolic extract of L. barbarum (EELB) was tested for its anticancer properties by performing the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, colony formation, cell proliferation, and scratch wound test. The impact of EELB on the signaling transduction pathways of Extracellular signal-regulated kinase (ERK1/2), protein kinase (AKT1), cyclin D1 and epithelial-mesenchymal transition (EMT) was also assessed by western blot. Results: The results showed that EELB can impede CAL-27 cell growth, proliferation and migration in-vitro. It even reduced the phosphorylation of ERK1/2 and AKT1 with concomitant downregulation of cyclin D1 (CCND1), cadherin 2 (CDH2), and vimentin (VIM) and upregulation of cadherin 1 (CDH1) expression suggesting its anti-proliferative and anti-EMT effects in oral cancer. Conclusion: Goji berry has good antiproliferative and anti-invasive properties. It affects potential EMT markers and signaling transduction pathways involved in oral cancers. Hence goji berry can be tried as a potential anticancer agent to manage oral squamous cell carcinoma.
Background: Removal of the microbial deposits (plaque and calculus) by performing effective scaling and root planing (SRP) is the primary and fundamental requirement for managing periodontal disease. Various adjuncts with antimicrobial, antioxidant, and anti-inflammatory properties are used as adjuncts to SRP for managing chronic periodontitis. However, with a rapid rise in antimicrobial resistance to several antimicrobial agents along with the increased risk of adverse effects, the use the conventional chemotherapeutic agents for managing periodontal disease is slowly declining. Hence, there is a urgent need to explore new plant-based products for treating periodontal disease. Lycium barbarum (L. barbarum), or goji berry, has recently gained popularity for managing chronic inflammatory and infectious diseases. However, its efficacy in managing periodontal diseases has never been explored. Hence the present study aims to evaluate the efficacy of L. barbarum mouthwash along with SRP compared to chlorhexidine for managing chronic periodontitis. Methods: The study is designed as a randomized clinical trial with 57 adult participants (Males:29; Females:28) with chronic periodontitis. The participants were divided randomly into two groups: One group used L. barbarum mouthwash and the other group used ‘0.2% chlorhexidine gluconate’ mouthwash. The changes in the gingival index (Gi), plaque index (Pi), bleeding on probing (BOP), clinical attachment loss (CAL), probing pocket depth (PPD), microbial load, and antioxidant levels (protein thiol) in saliva were noted at the baseline, at 15 days and one month. Results: A statistically significant difference was noted in the Pi (P-value = 0.791), Gi (P-value= 0.594), PPD (with P-value= 0.134), and microbial levels (P-value = 0.188) in both groups from the baseline. The protein thiol levels in saliva were increased only in the goji berry group. Conclusion: L. barbarum mouthwash along with SRP was found to be effective in managing periodontal disease.
