Abstract

Dental plaque identification uses disclosing agents to provide a better visual identification of dental plaque before the plaque control procedure. Studies show the use of natural ingredients for staining dental plaque, one of which is that red dragon fruit can be an effective alternative for evaluating dental plaque control. This scoping review aims to examine further natural dental plaque coloring from red dragon fruit. This literature review uses a scoping review study design that refers to the PRISMA-ScR analysis and uses the PCC framework. Article searches were carried out using key word (red pitaya) AND (disclosing agent), AND (dental plaque) in 5 online databases, namely PubMed, Science Direct, Wiley, SAGE, and Google Scholar. The selection of articles was carried out based on inclusion and exclusion criteria. Initial search obtained 170 articles, then selected according to inclusion and exclusion criteria resulting 9 articles. The results show dental plaque colorant from red dragon fruit extract can effectively color dental plaque as well as disclosing agents. Red dragon fruit extract meets the requirements for being a dental plaque coloring agent. At a concentration of 75%, red dragon fruit extract can color dental plaque well and produces optimal coloring at a concentration of 100%.

Abstract

Introduction: Nicotine is known to influence appetite suppression and energy expenditure, potentially contributing to the lower body mass index (BMI) observed among smokers. However, the short-term metabolic impact of switching from combustible cigarettes to electronic cigarettes (e-cigarettes) remains uncertain. Objective: This study aimed to evaluate the effect of transitioning from conventional cigarettes to e-cigarettes on BMI among young adult male smokers over a three-month period. Method: A prospective cohort study was conducted involving 47 male smokers aged 20–40 years. Participants were allocated into two groups: those who switched to e-cigarettes (n = 30) and those who continued smoking conventional cigarettes (n = 17). BMI was assessed at baseline and after three months. Data were analyzed using paired and independent t-tests to evaluate intra- and intergroup differences. Result: In the e-cigarette group, BMI slightly declined from 24.16 ± 4.42 to 24.06 ± 4.59 kg/m² (Δ = –0.11 ± 0.63, p = 0.379), whereas in the conventional group, BMI increased marginally from 22.54 ± 3.63 to 22.63 ± 3.63 kg/m² (Δ = +0.09 ± 0.52, p = 0.486). The between-group difference in BMI change was not statistically significant (p = 0.289). Conclusion: Short-term transition to e-cigarette use did not result in significant changes in BMI among young adult male smokers. These findings suggest that e-cigarettes are metabolically neutral over short durations and should not be regarded as effective tools for weight control. Further longitudinal studies are warranted to explore longer-term metabolic outcomes.

Abstract

Introduction: Periodontitis is an infectious disease that damages periodontal tissues and may lead to tooth loss. Aggregatibacter actinomycetemcomitans is one of the main pathogenic bacteria associated with periodontitis. Peperomia pellucida (L.) Kunth contains flavonoids, alkaloids, and tannins with antibacterial potential. This study evaluated its effectiveness against A. actinomycetemcomitans and determined its Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC). Materials and Methods: This laboratory experimental study used a post-test-only control group design. Antibacterial testing was performed using the serial dilution method in eight groups: extract concentrations of 3.125%, 6.25%, 12.5%, 25%, 50%, and 100%, 0.2% chlorhexidine as the positive control, and distilled water as the negative control. MIC was assessed by bacterial growth on Mueller–Hinton Agar, while MBC was determined by colony counts (CFU/mL). Data were analyzed using Kruskal–Wallis and Mann–Whitney tests. Results: Peperomia pellucida extract showed antibacterial activity against A. actinomycetemcomitans. MIC was achieved at 6.25% concentration with 92.5% inhibition, while MBC was achieved at 12.5% concentration with 100% bactericidal effect. Conclusion: Peperomia pellucida extract effectively inhibited and killed A. actinomycetemcomitans, with greater antibacterial activity at higher concentrations.
