Abstract

Gingivitis is the second most common disease that occurs in the oral cavity. The use of chlorhexidine as a gingivitis therapy agent has some side effects such as allergic reactions and bacterial resistance. Jasminum Sambac (L.) Aiton leaf nano-extract contains flavonoids, saponins, and tannins compounds reported to have an influence on wound healing process. The aim of this research was to determine the effect of observation time and concentrations of Jasminum sambac (L.) Aiton leaf nano-extract on the number of neutrophils, macrophages, and angiogenesis in the treatment of gingivitis-induced Sprague Dawley rats. Sixty male Sprague Dawley rats aged 2.5-3 months with body weight of 200-250 g were anesthetized with ketamine HCl (10 mg/kg BW) and xylazine (2 mg/kg BW) then induced using silk ligature 3.0 on the interdental of the mandibular incisor. The rats were divided into five groups and got daily spray using distilled water (negative control), nano-extract at a concentration of 40%, 45%, 50%, and 0.12% chlorhexidine (positive control). The rats were euthanized on the 1st, 3rd, 5th, and 7th days post-treatment. The tissues were processed histologically with HE staining. The number of neutrophils, macrophages, and angiogenesis were counted using a microscope (400x) and OptiLab Viewer® (13x) at five fields of view. The result of the Two Way ANOVA test showed that there were significant effect of concentrations and observation time, and interaction of both observation time and concentrations on the number of neutrophils, macrophages, and angiogenesis (p < 0.05). It can be concluded that observation time and concentrations of Jasminum sambac (L.) Aiton leaf nano-extract affected the number of neutrophils, macrophage, and angiogenesis in the treatment of gingivitis-induced Sprague Dawley rat (p < 0.05).

Abstract

Patients with diabetes are prone to recurring and even resistant Candidiasis, making treatment challenging. Many hypotheses proposed related to susceptibility of diabetic patients to Candida. The prevalence and species of Candida in a particular diabetic community might be different compared to other diabetic community. This study aimed to determine the prevalence of Candida colony and its species in the oral cavity of diabetic patients included in the CDM (Chronic Disease Management) program in Yogyakarta. One hundred patients with type 2 diabetes (n= 100) were recruited as the subjects of this study. The subjects were classified into controlled and uncontrolled Diabetes mellitus (DM). Samples of oral rinse solution were collected to determine the species of Candida and number of Candida colonies using CHROMagar Candida medium. There were 47 and 53 of subjects with controlled and uncontrolled DM, respectively. The mean number of Candida colony in the subjects with controlled diabetes (1003.13) was higher than that in the subjects with uncontrolled diabetes (478.43). The Candida colony most commonly identified in the subjects with controlled and uncontrolled diabetes were C. albicans and C. glabrata, respectively. Female patients had higher mean number of Candida colony (859.51) compared to male (299.21). The Candida colony most often identified in both genders was C. albicans. In addition, the subjects of this study consisted of 83 geriatric subjects and 17 non geriatric subjects, in which the mean number of Candida colony in the geriatric subjects (761.77) was higher than that in the non-geriatric subjects (545.71). The Candida colony most often identified in the geriatric subjects and non-geriatric subjects was C. albicans and C. glabrata, respectively. The Mann Whitney test demonstrated that there was a significant difference (p = 0.009) of the mean number of Candida colony between male and female. However, there was no significant difference of the mean number of Candida colony between ages (p = 0.060) and diabetic status (p=0.175). It can be concluded that the Candida species most commonly identified in all the subjects was Candida albicans with the mean colony number of 349.96, followed by C. glabrata (225.97), C. krusei (144.91), C. tropicalis (3.67), and other species (2.02).

Abstract

Denture stomatitis is an infection of the mucosa caused by bacteria such as Staphylococcus aureus (S. aureus) accumulating on the denture. Garlic (Allium sativum) contains antibacterial compounds that can be used as an alternative denture cleanser. The purpose of this study was to determine the inhibition effect of immersion in effervescent garlic ethanol extract (Allium sativum) against Staphylococcus aureus growth on heat cured acrylic dental plate. This research was a laboratory experiment in vitro using 40%, 50%, and 60% effervescent garlic ethanol extract. The samples were 12 pieces (n = 12) of heat cured acrylic plates which were divided into 3 treatment groups then incubated in S. aureus suspension for 24 hours and then immersed in an effervescent garlic ethanol extract for 6 hours. Bacterial colonies were counted using a colony counter and the data were analyzed using the One-way ANOVA and LSD Post hoc tests. The statistical analysis showed that the number of S. aureus colonies decreased along with an increased concentration of garlic ethanol extract. The results of the analysis showed that the 60% effervescent garlic ethanol extract had a significantly lower mean number of colonies compared to the 40% and 50% effervescent garlic ethanol extracts (p ≤ 0.05). This research concluded that effervescent garlic ethanol extract prevented the growth of S. aureus on the heat cured acrylic dental plate.

Abstract

Biocompatibility testing for a new implant material is necessary before clinical use. The materials for bone scaffolding must also go through biocompatibility tests both in vitro and in vivo. The purpose of this study was to compare different staining methods in histological preparations to assess the biocompatibility of the material to tissues. Twenty Wistar rats (n= 20), aged 4 months, males, weighing about 250-350 g were divided into 2 research groups, namely sub-cutaneous and bone implantation for 3, 14, and 30 days. The sample was a biodegradable material with gypsum and calcium carbonate as the basic ingredients. Histological stains were prepared in several ways using Hematoxylin Eosin (HE), Mallory, Toluidine Blue, Tartrate-resistant acid phosphatase polyclonal antibody (TRAP), and Chromogen 3,3 diaminobenzidine (DAB) after pre-performing a decalcification process with ethylenedinitril-o-tetra-acetic acid (EDTA). The observation was done using magnification ranging from 10X10 to 100X10 with a light microscope (Nikon eclipse E600) and OptiLab viewer. The results were displayed in the form of descriptions of images generated from different staining methods. Staining by the HE method is most often chosen because it is cheap and easy but the other staining methods such as Toluidine Blue, Mallory, and TRAP show better contrast. Tissue staining techniques with immunohistochemistry (DAB, VEGF) are used to evaluate cell and tissue responses by identifying specific proteins present.

Abstract

Aloe vera is known as a medicinal plant containing an active substance acemannan thought to play a role in accelerating wound healing. This study aims to determine the effect of aloe vera extract on the proliferation phase of oral mucosa wound healing in rats by looking at epithelial thickening, epithelial gaps closure, growth of new blood vessels, and connective tissue growth. This research is a pure experimental study with a post-test only control group design. On the left buccal mucosa of the mouth of 24 white Wistar rats (n = 24), an incision was made by scalpel with 10 mm length and 2.5 mm depth. The rats were divided into 4 groups: groups 1 and 2 as controls, while groups 3 and 4 were applied with aloe vera extract made by maceration technique. Wound tissue was observed histologically with Hematoxylin-Eosin staining under a microscope with an image analyzer for measuring the thickness of epithelium. The analysis of epithelial gap width used morphometry, and the number of capillaries was counted manually. Connective tissue thickness was measured with Image-J software. These were carried out on days 7 and 14 after treatment and the data were analyzed with the independent t-test and Mann-Whitney test. The results showed that aloe vera extract had no significant effect on epithelial thickening on day 7 (p = 0.701) nor on day 14 (p = 0.639), but a significant effect was shown on epithelial gaps closing (p = 0.049), connective tissue thickening (p = 0.004), and capillary increase on day 7 (p = 0.049). It could be concluded that aloe vera extract could potentially accelerate the epithelial gaps closure, connective tissue thickening, and capillary increase during the proliferation phase of the oral mucosa wound healing.

Abstract

Sodium hypochlorite (NaOCl) is currently the golden standard for root canal irrigation. NaOCl at a concentration of 5.25% to 6% can eliminate E. faecalis, but this concentration can increase the risk of toxic effects. Cyanobacteria spirulina is known to produce several secondary metabolites that have antimicrobial activity against gram-positive and gram-negative bacteria. The aim of this study was to determine the antibiofilm power of Cyanobacteria spirulina against the biofilms of Enterococcus faecalis at concentrations of 60 mg/ml, 70 mg/ml, 80 mg/ml, and 90 mg/ml. This research was a true experiment with a post-test only group design. The object of the research was divided into 6 groups. Group 1 was a negative control group, group 2 was a positive control group with 5% NaOCl, group 3, 4, 5, 6 were treatment groups given Cyanobacteria spirulina solution at a concentration of 60 mg/ml, 70 mg/ml, 80 mg/ml, and 90 mg/ml, respectively. Optical density (OD) of bacteria was bound by staining and analyzed by ELISA auto reader with a wave length of 595 nm (OD 595 nm). The results of the LSD test showed that the significance between K+ and P1, P2, P3 (p< 0.005), K+ and P4 (p= 0.129), P1 and P2 (p=0.449), P3 and P4 (p=0.178). Significance of p<0.0005 showed a significant difference between the groups. The data were analyzed using the one-way ANOVA test followed by a double comparison test with the Least Significance Different (LSD) Post Hoc test method. Cyanobacteria spirulina solution at a concentration of 90 mg/ml had the greatest inhibitory effect on the biofilm formation of Enterococcus faecalis.

Abstract

Synthetic dental fiber tape for fiber reinforcement (FRC) restoration is relatively costly and its availability is still limited in Indonesia, so natural dental fibers have been used as an alternative material. The aim of this study was to assess the effect of impregnation of various fiber tape toward the flexural strength and hardness of FRC. The materials used were natural Bombyx mori silk fibers (Indonesia), dental polyethylene tape (Construct Kerr, USA), dental Quartz tape (Quartz Splint UD, France), dental E-glass tape (Everstick TM, GC, Japan), silane coupling agent (Ultradent, Jordan), and composite resin (Denfil-Flow, USA). Five groups of samples consisted of FRC with various fiber tapes were prepared: unidirectional-silk, braided-silk, quartz, polyethylene, and E-glass. The five groups of FRC were tested to determine the flexural strength and hardness. The results were analyzed by one-way ANOVA, followed by LSD test. The results showed that the highest flexural strength was in the quartz group (496.84 ± 109.14 MPa), while the lowest was in the braided-silk group (139.39 ± 4.30 MPa). The highest hardness property was in the unidirectional-silk group (141.29 ± 25.17 VHN), while the lowest was in the braided-silk group (139.39 ± 4.30 VHN). The ANOVA showed that various fiber tapes significantly influenced the flexural strength and hardness of FRC (p < 0.05). The LSD showed that the unidirectional-silk, braided-silk, and polyethylene groups demonstrated no significant difference. The LSD for hardness showed that the unidirectional-silk group had a significant difference with the other groups (p < 0.05). It can be concluded that various fiber tapes influenced the flexural strength and hardness of FRC. Natural silk fibers showed comparable flexural strength and hardness with the other fiber tapes.

Abstract

Chronic inflammation in periodontitis results in continuous production of Reactive Oxygen Species (ROS), so the levels are excessive, causing destruction of the gingiva, periodontal ligament, and alveolar bone through a variety of mechanisms including DNA damage and the formation of proinflammatory cytokine. One way to prevent periodontal tissue damage caused by excessive ROS formation is by administering antioxidants. Coenzyme Q10 is a powerful antioxidant that is beneficial for inhibiting free radicals to prevent the progression of periodontal tissue destruction and accelerate healing processes. The purpose of this study was to evaluate the fibroblast proliferation of the combination of Coenzyme Q10 and vegetable glycerin compared to PerioQ. Materials used were made of original Coenzyme Q10 dissolved in glycerin that was prepared in a ratio of 2:8 and 1:9, and Perio Q as the control. Each group consisted of six samples (n = 6). Primary fibroblasts were derived from healthy gingival tissue. Observations on day-1, -3, and -5 using MTT assay at a wavelength of 550nm. Statistical analysis used a Two-Way ANOVA test followed by a Post Hoc test.  The experiment showed the absorbance values were high in all the groups, the highest value was on day 3, namely Coenzyme Q10 at a concentration of 2:8, followed by Coenzyme Q10 at a concentration of 1:9, and PerioQ. The statistical tests showed significant differences in the 3 groups (p < 0.05). It is concluded that Coenzyme Q10 in 1:9 and 2:8 concentrations were both as viable as Perio Q towards primary gingival fibroblast culture.

Abstract

Dental trauma mostly damages the maxillary anterior teeth, affecting the individual’s esthetics, functionality, and psychological well-being. Restorative dentistry treatment is required to obtain a natural appearance based on the smile design approach. The aim of this report is to characterize the procedure of complicated cosmetic restoration of the six maxillary anterior teeth, which results in straighter and more beautiful natural-looking smiles. A 32-year-old male patient presented with multiple crown fractures in the anterior maxillary teeth, resulting in an unaesthetics smile. The patient also had a deep bite. A comprehensive aesthetics dental treatment was carried out. The dental treatment plan had to be carefully executed by considering several factors such as dental convexities and contours, re‑establishment of function, and esthetics. Smile design should always be approached as a multi-factor decision-making, which enables the doctor to treat patients using a personalized and interdisciplinary approach.

Abstract

Injectable platelet-rich fibrin (i-PRF) refers to second-generation platelet concentrate. In this study, the results of i-PRF centrifugation were fractionated into three layers: yellow i-PRF, buffy coat, and red i-PRF. Injectable platelet-rich fibrin fractions used in this study were yellow i-PRF, red i-PRF, and a mix of both. This study aimed to examine the level of growth factor release of transforming growth factor beta 1 (TGF-β1) and platelet-derived growth factor (PDGF) in yellow i-PRF, red i-PRF, and a mix of yellow i-PRF and red i-PRF with the ratio of 1:1. A total of 10 ml of peripheral blood from healthy female donors was centrifuged (at 700 rpm in 3 minutes) to obtain i-PRF and fractionated into three layers. The upper yellow layer was taken as yellow i-PRF, while the bottom red layer was taken as red i-PRF and was taken together with the middle layer (buffy coat). The release of TGF-β1 and PDGF in each of i-PRF fractionation method, i.e. yellow i-PRF, red i-PRF, and a mix of yellow i-PRF and red i-PRF with a ratio of 1:1 was measured with ELISA. The measurement was observed for 24 hours, 3 days, 7 days, 10 days, and 14 days. Data analysis used the two-way ANOVA test with a significance level of 0.05 and a post hoc LSD analysis to establish group significance. The group of yellow + red i-PRF significantly released PDGF-AB (p < 0.05). TGF-β1 was the highest of all groups on day 14. All groups showed an increase in growth factor release from time to time. The fractionation method of injectable platelet-rich fibrin affected the release of growth factor of PDGF-AB and TGF-β1. The highest release of PDGF-AB and TGF-β1 was found in the yellow + red i-PRF group with a ratio of 1:1 in the 14-day group, which was significant with the other two groups (p < 0.05).
