Background: Tooth extraction is one of treatment frequently done by dentists in clinics, hospital, and even private practices. One thing that is needed to be observed after the treatment is the speed of wound recovery process. Mengkudu is commonly used as medicinal treatments, some of them to heal wounds, but there had never been research of the use of mengkudu fruit on wound recovery after tooth extraction. Purpose: The aim of this study was to investigate the effect of mengkudu gel in accelerating the escalation of fibroblast post tooth extraction on Dawley rats. Method: This study was used post test only control group design. Thirty male Dawley rats weigh between 250-300 grams, 3 months of age are being used. Tooth extraction is being done on lower left incisor. The 30 rats are divided into three groups, there are mengkudu (Morinda citrifolia Linn.) gel, poviclone iodine, and control group. The data were analyzed statistically using One-Way ANOVA and LSD. Result: The result of every tested group with Kolmogorof-Smirnov test showed p > 0.05. Examination showed there was significant difference in fibroblast amount between the group with mengkudu gel and two other groups (p < 0.05). Conclusion: The application of mengkudu gel can accelerate the escalation of fibroblast after the tooth extraction on Dawley rats.Latar Belakang: Ekstraksi gigi merupakan perawatan yang sering dilakukan oleh dokter gigi baik di klinik, rumah sakit, dan praktekpribadi.

Background: Open dentin is always covered by smear layer, therefore before restoration is performed, cavity or tooth which has been prepared should be clean from dirt. The researchers suggested that clean dentin surface would reach effective adhesion between resin and tooth structure, therefore dentin conditioner like citric acid was used to reach the condition. Even though citric acid is not strong acid but it can be very erosive to oral mucous. Several requirements should be fulfilled for dental product such as non toxic, non irritant, biocompatible and should not have negative effect against local, systemic or biological environment. Cytotoxicity test was apart of biomaterial evaluation and needed for standard screening. Purpose: This study was to know the cytotoxicity of 40, 50, 60% citric acid as dentin conditioner using MTT assay. Method: This study is an experimental research using the Post-Test Only Control Group Design. Six samples of each 40, 50 and 60% citric acid for citotoxicity test using MTT assay. The density of optic formazan indicated the number of living cells. All data were statistically analyzed by one way ANOVA. Result: The percentage of living cells in 40, 50 and 60% citric acid were 95.14%, 93.42% and 93.14%. Conclusion: Citric acid is non toxic and safe to be used as dentine conditioner.

Wound healing is basically a complex process in which cellular and matrix act in concern to re-establish the integrity of injury tissues. This process can be simplified to be healing process consisted of haemostatic, inflammation, cell proliferation and tissue remodeling. The aimed of this research was to know the influence of freeze drying 90% Aloe vera application as mandible collagen density modulator in extraction socket of incisive Cavia cobaya. This research was done using Post Test Only Control Groups Design and Cavia cobaya as the sample. Six samples of each control group and 90% Aloe vera group applied to test each collagen density for three days and seven days. Then, the data was analyzed statistically using Mann Whitney with 5% significance rate. The result of the study indicates that administering 90% Aloe vera can accelerate the growth of collagen density in healing process of extraction socket. The conclusion is 90% Aloe vera can modulate the density of collageneous fiber in socket of extraction incicivus tooth wound of Cavia cobaya.

Sweet represents the quality of taste pleased by human beings since the birth. However, if the consumption of sucrose in the diet is excessive, it can change the calcium balance of the body. The aim of this study was to know the effect from the increased sucrose concentration toward the content of calcium in tooth of wistar’s rats. The experiment used 21 days-age of male wistar rats with body weight from 45 to50 grams. They were divided into four groups, and each group consisted of 8 rats. Group I got 15% sucrose diet, group II 30%, group III 43% and group IV as a standard diet. Six weeks after treatment, these rats were anesthetized with ether and killed then by decapitation. The lower incisor was separated from jaw, the mass of each fraction was weighted. Atomic Absorption Spectrophotometer (AAS) in mg/g was used to determine the concentration of calcium in wistar’s tooth. One Way Anava test indicated that there were significant differences between group of treatment and the content of calcium in tooth (P < 0.05). TukeyHSD (Honestly Significance Difference) test indicated that there was a significant difference at group diet of sucrose 43% in tooth. It was concluded that the increased concentration of sucrose in diet could affect the decreased content of calcium in tooth of wistar rats.

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.

Background: Physical exercise has been proven to accelerate wound healing. Physical training itself consists of aerobic (continuous training) and anaerobic (interval training) exercise. The effectiveness of continuous physical exercise on post-tooth extraction wound healing is the focus of this study. Purpose: This study aims to investigate the differences in post-tooth extraction wound healing in Wistar rats (Rattus norvegicus) after aerobic and anaerobic exercise based on the number of fibroblasts and neovascularisation. Methods: Wistar rats were divided into three groups: the control group (K1); K2 undertook continuous aerobic exercise, swimming at 50% maximum swimming capacity (MSC) with an additional 3% bodyweight load; K3 undertook anaerobic continuous exercise, swimming at 65% MSC with a 6% load. The rats swam three times per week for six weeks. The number of fibroblasts and neovascularisation were examined three days after tooth extraction. Data was analysed using the one-way analysis of variance (ANOVA) and Least Significant Difference (LSD) tests (p<0.05). Results: There was a significant difference in the number of fibroblasts between the K2 and K3 groups. There was no significant difference between K2 and K3 in the amount of neovascularisation. Conclusion: There were differences in the number of fibroblasts but not neovascularisation after tooth extraction in Wistar rats given aerobic and anaerobic continuous training.
