Background: Tooth extraction, a common practice among the dental profession, causes trauma to the blood vessels during the wound healing process. The acceleration of wound healing, within which fibroblasts play an important role, is influenced by nutrition. Avocado leaves contain a variety of chemicals, including flavonoid compounds, tannins, katekat, kuinon, saponin and steroids/triterpenoid. Avocado leaves also contain glycosides, cyanogenic, alkaloids and phenols which function as anti-inflammatory, antibacterial and antioxidant agents. This avocado leaf content could be used as an alternative medicine to accelerate the wound healing process in post-tooth extraction sockets. Purpose: To determine the role of avocado leaves (Persea americana Mill) in accelerating fibroblast cells proliferation in tooth socket post-extraction. Methods: The sample was divided into four groups, a control group and three treatment groups. The treatment groups used avocado leaf extract and 3% CMC Na solution which was inserted into the tooth sockets of Wistar rats. Both the control and treatment groups had their mandibula decapitated with all the required specimens being prepared on the 3rd and 7th days of the experiment. Mandibular decapitation and tooth extraction socket were prepared by HPA (Histology Pathology Anatomy) with Hematoxylin Eosin (HE) staining. The fibroblast proliferation was analyzed by means of a light microscope at 400x magnification. The obtained data was analyzed using a t-Test. Result: The t-Test obtained a significance value 0.001 (p <0.05) between the control and treatment groups. The number of fibroblast cells increased in the group treated on the third day and decreased in the group treated on the seventh day. Conclusion: Avocado leaf extract (Persea americana Mill.) accelerates proliferation of fibroblast cells in Wistar rats post-tooth extraction.
Objective Topical application of ambonese banana (Musa paradisiaca var. sapientum (L.) kuntze) stem sap gel (GEGPA) on the socket wound area showed an increase in the expression of platelet-derived growth factor-BB, while decrease in the expression of matrix metalloproteinase-2 and 9. The aim of this study is to achieve standard formulation of GEGPA through stability, viscosity, distribution area, and drugs release for oral gel wound healing. Materials and Methods This is an in vitro and in vivo study with the randomized posttest only control group design. The gel was formulated according to the composition of each group by adding hydroxypropyl methylcellulose (HPMC), Lexgard, propylene glycol, and cold water to obtain 100 g of gel. Observations were made through the following tests: stability, viscosity, distribution area, drug release, and histopathological analysis of tooth extraction wound healing. Statistical analysis Data were analyzed using a one-way analysis of variance (α = 0.05) with GraphPad Prism-8 statistical software. Results The study showed that the GEGPA formulation was stable against changes in consistency, color, smell, homogeneity, and pH value. There is a significant difference between groups with respect to viscosity (p = 0.0001), adhesion (p = 0.004), dispersion (p = 0.000), and fibroblast cell numbers on days 3 and 5 (p = 0.007 and p = 0.001). There is no interaction between the active ingredients and the gel base of all formulations. Formulation 3 had better properties in terms of viscosity, broad distribution, and drug release compared with other groups. Application of GEGPA to tooth extraction wounds showed a significant proliferation of fibroblast cells on days 3 and 5. Conclusions The formulation of M. paradisiaca var. sapientum (L.) kuntze extract with HPMC and propylene glycol obtained a gel preparation, GEGPA, that was organoleptically stable and met the topical gel standard for wounds in the oral cavity.
Background. Streptococcus mutans is the leading cause of dental caries. One of many medicinal plants, purple leaf [Graptophyllum pictum (L.) Griff], which contains flavonoids, alkaloids, tannins, steroids, and saponins, is a potential antibacterial agent. Objective. This study aimed to determine the antibacterial activity of purple leaf extract (Graptophyllum pictum L. Griff) against Streptococcus mutans. Methods. Streptococcus mutans were suspended in several Graptophyllum pictum (L.) Griff extract concentrations in a BHIB medium using the dilution method so that the concentration of 100%, 50%, 25%, 12.5%, 6.25%, 3.12%, 1.56%, 0.78% were obtained. Each tube was incubated for 24 hours, then subcultured in a Tryptone Yeast Extract Cystine medium in a petri dish using a spreader. Each petri dish was set for 24 hours; the growth of the colony, using CFU/mL unit, was manually calculated. The samples were then subjected to microbiological analysis. The Tukey's Honest Significant Difference test was performed to determine if the relationship between the sets of data in the treatment group is statistically significant (p<0.05). Results. Purple leaf extract contains bioactive compounds such as flavonoid, alkaloid, tannin, triterpenoid/ steroid, and saponin. The Minimum Inhibitory Concentration (MIC) of Graptophyllum pictum (L.) Griff against Streptococcus mutans was in concentration 3.125%, and the Minimum Bactericidal Concentration (MBC) was in concentration 6.25%. Conclusion. Purple Leaf Extract [Graptophyllum pictum (L.) Griff] has antibacterial activity against Streptococcus mutans.
