ABSTRACT
BACKGROUND: The clinical use of antimicrobial agents for managing aphthous ulcers and periodontal diseases has long been a subject of intensive research by numerous investigators. As concerns over the side effects and antibiotic resistance associated with conventional therapies persist, there has been a concerted effort to explore alternative medicinal approaches. In line with this objective, our study introduces a novel herbal gum paint designed specifically to address the therapeutic needs of individuals suffering from oral ulcers and periodontal diseases. MATERIALS AND METHODS: The herbal formulation utilized in our study was prepared using extracts derived from Licorice (Glycyrrhiza glabra) and Triphala, a combination of three fruits: Emblica officinalis, Terminalia chebula, and Terminalia belerica. These ingredients were selected based on their documented medicinal properties. The preparation process involved extraction and formulation techniques optimized for maximum efficacy. Antimicrobial activity was assessed using the bacterial culture method, where the formulation's ability to inhibit the growth of specific bacterial strains relevant to oral health was tested. Meanwhile, cytotoxicity was evaluated using the Brine Shrimp Assay method. Statistical analysis was conducted using a one-way analysis of variance (ANOVA) and Tukey post hoc test to validate the significance of our findings with statistical significance set at p<0.05. RESULTS: The formulation exhibited significant activity against microbes when compared to the control. The cytotoxic activity was present at a concentration of 60 and 80µL, which indicated safe usage within specified concentration ranges, highlighting its potential for clinical application without adverse effects on biological systems. Statistically significant differences were obtained between the antimicrobial activity of the formulated gum paint and the commercial gum paint against Candida albicans species at 25 µL and 80 µL (p=0.00). CONCLUSION: The study underscores the promising therapeutic potential of the herbal gum paint developed in this research. By harnessing the natural antimicrobial and anti-inflammatory properties of Licorice and Triphala, the formulated gum paint showed efficacy against C. albicans. These findings contribute to the growing body of evidence supporting the integration of herbal remedies into mainstream oral healthcare practices. Future investigations could further elucidate the mechanisms underlying its therapeutic actions and explore its broader clinical applications in diverse patient populations.
ABSTRACT
Myoepithelioma is an uncommon benign tumor of the orofacial region arising from the salivary glands. These tumors are composed of specifically myoepithelial cells lacking ductal differentiation and were initially considered as a type of pleomorphic adenoma. Though they commonly arise from the parotid gland, there are a few cases that emerge from the minor salivary glands of the palate and oral cavity. Myoepitheliomas resemble many other tumors arising from the palate including pleomorphic adenoma. This report depicts a case of myoepithelioma of the minor salivary gland of the palate in a 23-year-old patient and the successful management of the lesion.
ABSTRACT
Background The current study demonstrated improved efficiency of commercially pure titanium (CP-Ti) dental implants with a biocompatible coating of selenium (Se) and hyaluronic acid (HA). Methods The sol-gel solution was made with hyaluronic acid and selenium nitrate in a 1:1 ratio. The coating sample was subjected to characterization studies such as Fourier Transform Infrared (FTIR) spectroscopy, surface morphology analysis, contact angle, etc., to confirm the coating. The antimicrobial activity of the coating was studied by analyzing the zone of inhibition. Results The FTIR spectroscopy was analyzed to confirm the functional groups of Se/HA. The surface morphology of the coated sample appeared as tiny needles with a plate-like surface. The potentiodynamic polarization studies revealed that the coated Ti samples exhibit superior corrosion resistance. The antimicrobial activity of Staphylococcus aureus was found to be more effective at a concentration of 100 mg. Furthermore, the basic criteria of biomaterials were analyzed for hemocompatibility studies, which suggested a non-hemolytic character. Conclusion The biocompatible coating of Se and HA has proven to be of superior corrosion resistance and antimicrobial activity resistance, which validate the usage of dental implants.

ABSTRACT
Aim To assess the anti-inflammatory and antioxidant properties of Calendula officinalis tea formulation. Materials and methods In this study, a formulation of 2 grams of dried marigold flower petals and 100 milliliters (ml) of distilled water was subjected to anti-inflammatory testing using albumin denaturation assay and anti-protease activity and antioxidant testing by DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) assay. An independent sample t-test was done to compare the anti-inflammatory and antioxidant potentials of marigold tea formulation and control using SPSS version 22.0 software (IBM Corp., Armonk, NY), and any p-value less than 0.05 was considered statistically significant. Results The highest anti-inflammatory and antioxidant activities of marigold extract were exhibited at 10 microliters (µl) and 20 µl (p-value = 0.002 and 0.000), respectively. The anti-inflammatory activity was higher than the control at all concentrations, whereas the antioxidant activity was higher at lower concentrations when compared to higher concentrations. Conclusion Marigold flower tea formulation exhibited better anti-inflammatory and antioxidant activities than the controls and therefore could be evaluated as a potential therapeutic agent.
ABSTRACT
Oral squamous cell carcinoma (OSCC) is the most common head and neck cancer with several risk factors. Exosomes are extracellular vesicles generated by the fusion of multivesicular structures with the cell membrane and play an important role as intercellular messengers. MicroRNA (miRNA) is a noncoding RNA and regulates post-transcriptional modification. The present systematic review aims to identify and correlate the possible association and role of circulating exosomes with OSCC. Using the search strategy, articles fulfilling the inclusion criteria, published between January 2012 to March 2022, were retrieved from online databases including PubMed, Scopus, Web of Science, and Cochrane Library. About 904 articles were found using an electronic database and a human search. After reviewing the titles and abstracts, 614 studies were eliminated, and duplicate articles were removed. Five studies were included in this systematic review. Circulating exosomal expression of miRNA27, miRNA 21, and miRNA 155 showed significant upregulation in OSCC patients. Circulating exosomes could be potential biomarkers to be used in the detection of patients with OSCC. More studies are warranted in this area to gain a better understanding of the pathophysiology of OSCC and the function of molecular markers from circulating exosomes. Understanding the role of molecular markers from circulating exosomes in pathogenesis will provide a better understanding of the development of the disease, necessitating more study in this area. According to this review, circulating exosomes might be a potential approach to the identification of OSCC.
ABSTRACT
Background Tobacco usage in the form of smoking or chewing has increased the risk of oral potentially malignant disorders (OPMDs) and oral cancer. These deleterious habits are also related to changes in dentition and the oral mucosa. Aim The aim of our study was to evaluate the oral changes associated with tobacco usage among residents of Sri Ganganagar. Materials and methods This study was conducted among the residents of Sri Ganganagar, Rajasthan, India, using stratified cluster random sampling, prestructured questionnaires, and detailed oral examination. A total of 100 patients with a previous history of tobacco usage were enrolled in this study after obtaining informed consent. Age- and gender-matched controls were also evaluated to correlate the findings. Clinical details were documented, including the Oral Hygiene Index-Simplified (OHI-S), Decayed-Missing-Filled Teeth (DMFT) index, Community Periodontal Index (CPI), loss of attachment, dental findings, and oral mucosal changes. Suspicious lesions were stained with toluidine blue, and a biopsy was performed for histopathological evaluation. The tabulated results were statistically analyzed using the Statistical Package for the Social Sciences (SPSS) version 21.0 (IBM SPSS Statistics, Armonk, NY, USA) for significance. Results Attrition, abrasion, and erosion of teeth were more frequent in tobacco users than in controls. Smoker's palate, tobacco pouch keratosis, and leukoplakia were commonly noted mucosal lesions. The mean values of the parameters of the DMFT score (3.560), CPI score (2.190), and loss of attachment score (0.542) were higher among tobacco users, and it was statistically significant (P value < 0.05). Out of 100 patients, 17 had suspicious lesions. It included seven cases of oral submucous fibrosis (OSMF), two cases of tobacco pouch keratosis, and eight cases of leukoplakia. Toluidine blue staining and biopsy were performed. Histopathological examination of suspicious lesions revealed hyperkeratosis, various grades of epithelial dysplasia, and differing inflammatory responses. Out of 17 biopsied cases, there were two cases of hyperkeratosis with severe epithelial dysplasia, four cases of hyperkeratosis with moderate epithelial dysplasia, two cases of hyperkeratosis with mild dysplasia, two cases of superficially invasive squamous cell carcinoma, five cases of advanced OSMF, and two cases of moderately advanced OSMF. Conclusion Tobacco usage produces visible changes in dentition and latent alterations in the oral mucosa. Suspicious lesions should always be referred for histopathological examination to identify oral potentially malignant disorders and oral cancer so that prompt treatment could be initiated. Patient education is mandatory to avoid the usage of tobacco in any form.
ABSTRACT
OBJECTIVES: The aim of this study was to evaluate the prevalence of CYP2 C9 polymorphism among healthy controls and patients with oral squamous cell carcinoma (OSCC) and to analyze the risk of disease development. We also investigated the interaction between CYP2 C9 wild type and the polymorphic variants with benzo[a]pyrene by using molecular docking analysis. STUDY DESIGN: The study included 46 patients with OSCC and 46 controls. Amplification of the genomic DNA was done by using allele-specific polymerase chain reaction and then analyzed by using agarose gel electrophoresis. Molecular docking was then carried out to determine the interaction of CYP2 C9*1, CYP2 C9*2, and CYP2 C9*3 with benzo[a]pyrene. RESULTS: In the OSCC group, CYP2 C9*2 and CYP2 C9*3 polymorphisms were 17.4% and 15.2%, respectively, and in the control group, they were 8.7% and 6.5%, respectively. The OSCC group showed a statistically significant (P = .043) increase in the prevalence of CYP2 C9 polymorphic variants compared with the control group. The docking analysis showed benzo[a]pyrene to bind specifically to the altered single nucleotide catalytic site in the polymorphic CYP2 C9*3 enzyme. CONCLUSIONS: This study demonstrates that functionally important CYP2 C9 polymorphism exists among patients with OSCC, with a modest increase in the risk of disease development in those individuals who acquire these poor metabolizing variants. The modified docking of CYP2 C9*3 with benzo[a]pyrene signifies altered metabolism in vivo.

BACKGROUND: Collagen is a significant structural protein, the integrity of which is essential to be maintained for proper homeostasis. Oral submucous fibrosis (OSMF), being a collagen metabolic disorder, may be subject to changes in amino acid profiling. AIM: The present study was attempted to evaluate the amino acid profile to assess its feasibility as a biological marker in OSMF. MATERIALS AND METHODS: The study group comprised of 13 patents with OSMF and the normal group comprised of 13 normal patients without associated habits or systemic disorders. Venous blood was collected from the antecubital vein, plasma was separated and the plasma was then subjected to high profile liquid chromatographic analysis. RESULTS: The assay levels of threonine, alanine and tyrosine did not yield any significant results. The decreased assay levels of valine, Isoleucine and the increased assay level of methionine and glycine observed in group II yielded significant results in correlation with the control group. The decreased assay level seen in phenylalanine in group II and III in correlation with group IV is statistically significant. CONCLUSION: A few amino acids have been identified which can be used as biological markers for the severity of the disease such as valine, methionine and phenyl alanine. Large scale studies are required to elucidate the potential of these biological markers.
