Background: A study with female animal models is important because the system immune of females is remarkably different from the male because of interaction between sex hormone and immune system. Interleukin-17 (IL-17) plays an important role in immune response toward Candida albicans (C. albicans) infection and Erythrocyte Sedimentation Rate (ERS) is an easy and sensitive test to assess the inflammation. Purpose: This study aimed to evaluate C. albicans infection, analyse the IL-17 levels and ESR in a female animal model of oral candidiasis. Methods: Female Wistar rats were used as oral candidiasis animal model. The rats divided into three groups (pre-treatment group (P0), 5th-day post-treatment group (P1) and 8th-day post- treatment group (P1). Each group consists of six rats. After the adaptation period, the P0 was sacrificed. The drinking water of the P1 and P2 was added tetracycline HCl 500mg /1L. On the day before and after inoculation C. albicans, Methylprednisolone was injected. Ten minutes before inoculation with 0.3 ml C. albicans 9.4 x 107/mL, rats were sedated by CPZ 0.7 mg IM. The rats in P1 group were sacrificed after five days and in P2 were sacrificed eight days after inoculation. The IL-17 plasma levels measured by enzyme-linked immunosorbent assay (ELISA), decreased on the 5th day but not on the 8th-day post-treatment. The obtained data were analyzed by parametric and non-parametric tests according to normality and homogeneity of the data with p<0.05. Results: The colony forming unit (CFU) of C. albicans collected over the mouth on increased almost 8-fold and on 8th-day post-treatment almost 3-fold compared with pre-treatment. The ESR increased on the 8th day but not on the 5th-day post-treatment. Conclusion: The IL-17 level was decreased on the 3rd day, ESR increased on eight days after inoculation of C. albicans in female rats’ model of oral candidiasis.
Background: The compressive strength of orthodontic tooth movement will be distributed throughout the periodontal ligament and alveolar bone, resulting in bone resorption on the pressure side and new bone formation on the tension side. Caffeine, a member of the methyl xanthine family, represents a widely-consumed psychoactive substance that can stimulate osteoclastogenesis through an increase in RANKL. A 3D Micro-Computed Tomography (µ-CT) x-ray device can be used to measure orthodontic tooth movement and changes in periodontal ligament width. Purpose: The purpose of this research was to analyze the effects of caffeine on the distal movement distance of two mandibular incisors using 3D µ-CT. Methods: The research subjects (guinea pigs) were randomly divided into four groups. Of the two control groups created, one received two weeks of treatment and the other three weeks. The members of these two control groups were subjected to orthodontic movement but received no caffeine. Meanwhile, the other two groups were treatment groups whose members also received either two or three weeks of treatment. In these two treatment groups, the subjects were subjected to orthodontic movement and received a 6 mg/500 BM dose of caffeine. The orthodontic movement of the subjects was induced by installing a band matrix and orthodontic bracket on each mandibular incisor to move distally by means of an open coil spring. Observations were then conducted on days 15 and 22 with µ-CT x-rays to measure the distal movement distance of the two mandibular incisors and the width of the periodontal ligament. Results: The administration of caffeine increased the tooth movement on day 15 (p<0.05) and day 22 (p<0.05). The increase in the tooth movement on day 22 was greater than that on day 15 (p<0.05). The width of the periodontal ligament on the pressure side of the treatment groups experienced greater narrowing than that of the control groups (p<0.05). Meanwhile, the width of periodontal ligament on the tension side of the treatment groups widened more than that of the control groups (p<0.05). Conclusion: µ-CT x-ray can be used to evaluate the extent of orthodontic movement in addition to the width of the mandibular incisor periodontal ligament during orthodontic tooth movement. Moreover, it has been established that the administering of caffeine can improve orthodontic tooth movement.
Fusobacterium nucleatum is a bacteria found in normal flora of the oral cavity that plays a role in the occurrence of periodontal disease. The prevalence of periodontal disease in Indonesia reaches 70%. One treatment by using medicinal plants is robusta coffee beans. Robusta coffee beans contain volatile acids, chlorogenic acids, caffeine acids, phenols and caffeine suspected to be antibacterial. The objective of this study was to determine the inhibition of coffee robusta extract on growth of Fusobacterium nucleatum. This study used disc diffusion method with 4 samples in each study group. The study group consisted of 6 treatment groups (12,5%, 25%, 50% and 100% coffee robusta extract), positive control group (chlorhexidine gluconate 0,2%), and negative control group (sterile aquades). Data were analyzed using One Way Anova test and LSD (Least Significant Difference) test. Coffee robusta extract has the ability to inhibit the growth of Fusobacterium nucleatum. The concentration of coffe robusta extract 100%, 50%, 25%, 12,5% have same ability to inhibit the growth of Fusobacterium nucleatum.
Background: Gingivectomy is a periodontal surgical procedure that eliminates excess gingival tissues by excision, usually to remove a gingival pocket which leads to scars and recontours the gingival to its proper anatomical form. Wound healing is a process to restore the missing functions and structures of a tissue due to injuries or inflammations. Robusta coffee bean contains many bioactive compounds that can accelerate the wound healing process. The study aimed to determinate the effectiveness of robusta coffee bean extract gel with concentration 40%,50%,60% on collagen fibers density in post-gingivectomy wound healing Method: 36 Wistar rats were divided into 9 groups: control, gingivectomy without therapy, gingivectomy +40% robusta coffee bean extract gel, gingivectomy +50% robusta coffee bean extract gel, and gingivectomy+60% robusta coffee bean extract gel. The last 4 groups were divided again into day 3 and 7 euthanasia. The results were processed by Trichrome Mallory to visualized the collagen fibers and then measured by ImageJ software. Result: Robusta coffee beans extract gel therapy with concentration 40%, 50% and 60% had higher average collagen fibers density compared to group without therapy. Conclusion: Robusta coffee bean extract gel increased the density of collagen fibers in post-gingivectomy wound healing PENDAHULUANGingiva adalah bagian dari mukosa mulut yang memiliki fungsi utama sebagai perlindungan
Polyphenols are one of the active substances in the Robusta coffee beans with various benefits for humans’ health including anti-inflammation. neutrophil cell (polymorphonuclear PMN) plays a significant role as the primary immune response against foreign agent. Inflammatory response is characterized by the production of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α). Hence, the purpose of this study is to determine anti-inflammation capacity of Robusta coffee beans polyphenols extract on the TNF-α production in neutrophil cells. Neutrophil was derived from human peripheral venous blood by means of gradient density method. One hundred microliter of neutrophil (1,5x103 cell) was incubated with 3.13%, 6.25%, 12.5%, 25% polyphenol extract and exposed with 100 μl of Lipopolysaccharides (LPS) 25 mg/ml. The production of TNF-α were determined by ELISA. Data were analyzed by one way Anova. Polyphenols of Robusta coffee bean extract was shown to inhibit TNF-α production in LPS-exposed neutrophil cells compared to controls. Whereas, LPS-exposed neutrophil increased TNF-α production. The most effective concentration to inhibit TNF-α production was 12.5%. It was concluded that polyphenols of Robusta coffee beans has anti-inflammatory properties as indicated by its ability to decrease TNF-α levels.
