Abstract

Injury can be accidental, intentional, or disease-related. Moringa leaves may help heal wounds. The research aims to test and assess the effects of Moringa oleifera flower extract on dermapen wound healing collagenization in male Wistar strain white rats, an obese model, and their histological findings—quantitative True Experimental Study with Post-Test Only Control Group Design. Twenty-four male Wistar white rats (Rattus norvegicus) were sampled. Accumulation of Test Animals, Moringa Flower Extract Preparation, Phytochemical Screening / Secondary Metabolite Test, Treatment Process (200, 400, and mg/kgBW of Moringa flower extract), Wound Observation, Histopathological Skin Preparations, and Histopathological Examination of Preparations were the research procedures. Window data was analyzed using SPSS 25.0 and One Way ANOVA with a 95% confidence level (p < 0.05). The Post Hoc Test with LSD was used for further analysis. The research results found Moringa flower extract at 200mg/Kg BW, 400mg/KgBW, and 600mg/KgBW could expedite wound healing and improve collagen density in obese mice's dermapen wounds. The 600mg dose was most beneficial. Research conclusions: Moringa flower extract aids dermapen wound healing, collagenization, and obesity weight loss, according to a study.

Abstract

Sodium hypochlorite (NaOCl) and EDTA are commonly used irrigants due to their antimicrobial properties and ability to dissolve both organic and inorganic components. However, the use of these chemicals at varying concentrations and durations can affect the physical and chemical properties of root canal dentin. Recently, propolis has gained attention as an alternative irrigant because it shows similar potential to conventional irrigants. The aim of this study is to examine whether there are differences in the effects of propolis extract, NaOCl, and EDTA on the microhardness of root canal dentin. This study utilized 24 single-rooted premolar teeth. The crowns were removed, and the roots were longitudinally split into two halves. Samples were randomly divided into six groups (n=8), each immersed in 8% propolis, 20% propolis, 30% propolis, 2.5% NaOCl, 5% NaOCl, and 17% EDTA. The microhardness of root canal dentin was measured using a Vickers Hardness Tester before and after immersion. Data were analyzed using One Way ANOVA. The results showed that 8% propolis had the smallest decrease in microhardness among all treatment groups, with an average difference in initial and final microhardness of 3.68, followed by 20% propolis, 2.5% NaOCl, 5% NaOCl, 30% propolis, and 17% EDTA. The conclusion of this study is that there are significant differences (p<0.05) among the treatment groups regarding the microhardness of root canal dentin. Extracts of 8% and 20% propolis can be used as alternative irrigants. DOI : 10.54052/jhds.v4n3.p255-264

Abstract

The habit of chewing betel quid in the community is based on the belief that its consumption can strengthen teeth. However, this practice may have an impact on the dental restorative materials used. Nanohybrid composite resin is one of the restorative materials widely applied in current dental practice. This study was conducted to determine the effect of immersion in areca nut seed extract on the surface roughness of nanohybrid composite resin. This research was an experimental laboratory study with a pre-test and post-test group design. A total of 30 nanohybrid composite resin specimens were used as research samples and divided into three treatment groups, each of which was immersed in areca nut seed extract at concentrations of 2%, 4%, and 6%. Surface roughness was measured using a Surface Roughness Tester, while data analysis was performed using the Wilcoxon statistical test. The results showed that the mean surface roughness values of nanohybrid composite resin before immersion in areca nut seed extract at concentrations of 2%, 4%, and 6% were 0.187±0.015, 0.192±0.014, and 0.202±0.016, respectively. After immersion, the surface roughness values increased to 0.362±0.055, 0.383±0.048, and 0.403±0.019. The Wilcoxon test indicated a statistically significant difference in surface roughness values before and after immersion in areca nut seed extract (p = 0.005; p < 0.05). Based on these findings, it can be concluded that immersion in areca nut seed extract at concentrations of 2%, 4%, and 6% has a significant effect on increasing the surface roughness of nanohybrid composite resin (p < 0.05).
