    International Journal of Dental Hygiene, 2025
    ObjectivesTo evaluate the changes in salivary levels of catalase (CAT), total antioxidant capacity (TAC) and IL‐1β (primary outcomes) as well as gingival health and oral health‐related quality of life (OHRQOL) 1 month after the consumption of matcha and green tea in adult patients with gingivitis.MethodsThis study was a parallel randomized clinical trial. Forty gingivitis adult patients were randomly assigned to drink either matcha or green tea cup twice daily for a duration of 1 month. They were asked to keep their habitual oral hygiene measures. Plaque index (PI) and bleeding on probing (BOP) were recorded. In addition, saliva was collected at baseline and 1 month after tea consumption. Salivary levels of CAT, TAC and IL‐1β were determined by ELISA. Each participant was asked to fill OHIP‐14 questionnaire before and after tea consumption.ResultsFollowing tea intake, 40.6% of the study sample had healthy gingiva. Both groups similarly showed reductions in PI (0.32 ± 0.11–0.22 ± 0.08) and BOP (0.24 ± 0.08–0.13 ± 0.07) scores after tea consumption. There was a significant difference between mean TAC before and after matcha tea consumption only. Non‐significant reductions in salivary levels of CAT and IL‐1β were detected after tea consumption. OHRQOL of participants was improved after tea, both types, consumption.ConclusionDespite study limitations, daily consumption of matcha and green tea might be beneficial as they potentially enhance OHRQOL of individuals with gingivitis and reduce the extent of gingivitis despite non‐significant changes in salivary antioxidants and IL‐1β levels.

    Oral Health and Preventive Dentistry, 2024
    PURPOSE To assess the antioxidant and antineoplastic effects of Hibiscus sabdariffa Linn. on oral squamous cell carcinoma cells. MATERIALS AND METHODS Human squamous cell carcinoma HSCC cells were tested for cytotoxicity by a methanol extract of Hibiscus sabdariffa (MEHSP). After 24, 48, and 72 h, the MTT assay and Trypan blue exclusion test were used to determine cell survival and death. 2, 2-diphenyl-1-picrylhydrazyl (DPPH), DNA Protection Assay (DPA), and ferric reducing antioxidant power assay (FRAPA) measured the antioxidant activity of MEHSP. RESULTS The antioxidant activity (%) ranged from 47.92-82.24 in the DPPH test, 11.61-73.65 in the DPA, and 4.97-52.09 in the FRAPA. The HSCC in-vitro cytotoxicity assay showed dose- and time-dependent cell viability. MEHSP at 5 μg/ml inhibited viable cells, while increasing MEHSP doses decreased cell viability. The Trypan blue exclusion test showed that MEHSP significantly reduced cell viability at 24, 48, and 72 h. CONCLUSION Hibiscus sabdariffa contains antioxidant and HSCC-cytotoxic properties.
  • Association of IL-4 Polymorphism with Severe Periodontitis in a Sample of Iraqi Population

    Folia Medica, 2024
    Introduction: Specific bacterial plaque and environmental factors cannot be considered the only cause of periodontitis. Still, several genetic factors affect the host response to the bacteria, like gene polymorphisms in anti-inflammatory cytokines. Several studies have reported that clones of T-helper 2 lymphocytes (TH2) are generated in response to dental plaque in periodontitis patients, while in healthy individuals, they are regulated by T-helper 1 (TH1) lymphocytes. Accordingly, such patients consistently produce more IL-4 (TH2) in response to bacterial stimulation, whereas healthy controls with intact periodontal tissues produce a significantly higher level of TH1. Aim: The current work aimed to investigate the association between variations in IL-4 gene polymorphisms and susceptibility to periodontitis. Materials and methods: The current study employed a case-control observational methodology involving 120 Iraqi participants. These participants were divided into two groups: the periodontitis group, consisting of 63 subjects, and the control group, consisting of 57 subjects. Clinical periodontal parameters were assessed for all participants, and subsequent genetic analysis of IL-4 was conducted using DNA sequencing. Venous blood samples were collected from each participant enrolled in the study. SPSS was used to conduct descriptive and inferential statistical analyses, including odds ratio, Hardy-Weinberg equilibrium, and Pearson correlation. Results: The Hardy-Weinberg equilibrium for study groups regarding the rs1801275 and rs1805016 polymorphisms of IL-4 showed a non-significant difference between the observed and expected genotypes in both groups involved in the study and the overall sample. Moreover, there was no significant association between the IL-4 gene polymorphism and the clinical periodontal parameters. Conclusion: The research conducted revealed a lack of correlation between IL-4 gene polymorphism and the susceptibility to periodontitis in individuals from Iraq. More research with a bigger sample size is required to validate these findings.

  • Short-Term (4 Day) Effects of Oral Rinsing with Miswak and Green Tea on Gingival Crevicular Fluid Flow and IL-1β Levels: A Pilot Study
    Rasha Salah, Hayder Raad Abdulbaqi
    Healthcare Switzerland, 2023
    Despite the antiplaque effect of mouth-rinsing with a combination composed of miswak (Salvadora persica L.) and green tea (Camellia sinensis var. assamica) extracts, no data are available regarding its effect on gingival tissue at the molecular level. This pilot study aimed to assess the effect of oral rinsing with this combination on gingival crevicular fluid (GCF) flow and IL-1β levels. Ten subjects rinsed with either the combination, 0.12% chlorhexidine gluconate (CHX) or distilled water without toothbrushing for 4 days after receiving baseline polishing. GCF IL-1β concentration, influx, resting volume and plaque quantity were measured at baseline and after 4 days for each intervention. No significant differences in GCF flow or resting volume were detected after rinsing with the different mouthwashes. A significant increase in GCF IL-1β concentration was evident only after rinsing with distilled water. Rinsing with combination induced a significant reduction in GCF influx (−0.086 ± 0.222) compared to CHX (0.088 ± 0.247) and distilled water (0.075 ± 0.201). Less plaque was detected after rinsing with combination and CHX. Short-term oral rinsing with this combination could potentially induce no significant changes in GCF flow and IL-1β concentration, and might retard inflammation. Thus, it might be considered in the production of natural oral healthcare products.

    Journal of Herbal Medicine, 2020
    Background A combination of 0.25 mg/ml green tea (leaves of Camellia sinensis var. assamica) and 7.82 mg/ml Salvadora persica L. root-sticks aqueous extract mouthwash (CoM) has been reported to exhibit antibacterial and anti-adherence effects against primary plaque colonizer biofilm in vitro and an antiplaque effect for a period of 24 h (h) in vivo. Aim To assess the antiplaque effect of CoM during a four-day period. Methods A four-day plaque re-growth randomized crossover trial was conducted. A week after receiving dental scaling and polishing, all participants (n = 15) underwent polishing at baseline and a rinse with 15 ml of randomly allocated mouthwash (CoM, 0.12 % chlorhexidine (CHX) mouthwash, or placebo [Plc]) twice daily without oral hygiene measures for four days. After 2 h, samples of saliva were collected, using a quantitative polymerase chain reaction, to determine the bacterial load. After 24 h and four days’ time points, plaque quantity (using digital plaque image analysis) was recorded. Subsequently, the participants entered a six-day washout period with regular oral hygiene measures. The same protocol was repeated for the next two mouthwashes. Results CoM significantly reduced plaque accumulation (31.933 ± 10.025) compared to Plc (54.629 ± 17.555) for a period of four days; a comparable effect was ascribed to CHX (34.903 ± 11.871). Moreover, it significantly reduced the amount of Streptococcus sanguinis, Actinomyces viscosus, and Actinomyces naeslundii (primary colonizers) in saliva. Conclusion Using CoM for four days twice daily could reduce plaque accumulation and might be considered as an alternative to synthetic mouthwashes.
