Abstract

Background: Beta titanium orthodontic wire is known to have good corrosion resistance but is weak in acidic environments, which advance the corrosion rate. One natural inhibitor that can be used to decrease corrosion is kiwi peel extract, which has a high antioxidant level. Purpose: This study aims to examine the ability of the extract to decrease the corrosion rate and microstructural changes of beta titanium at an acidic pH (pH 5). Methods: The samples used were beta titanium with a diameter of 0.016 x 0.022 in and a length of 6 cm. A total of 28 samples (n=28) were divided into four groups—a control group immersed in pH 5 artificial saliva and three treatment groups immersed in kiwi peel extract at concentrations of 400, 500, and 600 ppm (n=7), respectively. The samples were immersed for seven days at 37oC in an incubator. The corrosion rate was tested using the weight-loss method and microstructure change was analyzed using a scanning electron microscope (SEM). Results: One-way ANOVA showed that there are significant differences in corrosion rates between beta titanium immersed in artificial saliva and beta titanium immersed in kiwi peel extract with p=0.01 (p<0.05). SEM analysis results showed that the group with the least surface changes was the one immersed in 400 ppm of kiwi peel extract. Conclusion: Weight-loss and SEM methods show similar results. Kiwi peel extract proved to decrease the corrosion rate and changes in the microstructure of the wire most effectively at a concentration of 400 ppm.

Abstract

Background: Periodontitis is a chronic inflammatory disease of the periodontal tissue that is characterized by alveolar bone resorption. This occurs due to an imbalance of osteoblast and osteoclast during the bone formation and resorption processes. In order to obtain complete regeneration of periodontal tissue, bone grafting is frequently used in periodontal surgical therapy. Although each material has disadvantages, safe graft materials derived from animal sources can be employed as an alternative to bone graft materials. Osteoblast, osteoclast, calcified bone matrix, type I collagen, osteonectin, and hydroxyapatite can all be found in gourami scales, a form of food waste. BMP4 has osteoinduction functions, which are important in bone metabolism. Through angiogenic activity, FGF2 also contributes to periodontal regeneration. Purpose: The aim of the study was to assess the expression of BMP4 and FGF2 after the treatment group had been given gourami fish scale extract. Methods: Thirty-two experimental three-month-old male Wistar rats (150-200g) were randomly divided into four groups: a seven-day control group, a seven-day treatment group, a 14-day control group, and a 14-day treatment group. One mandibular incisor was extracted from each Wistar rat. The post-extraction socket was filled with blood for the control group and collagen extract for the treatment. Results: The one-way ANOVA test showed a significance level of 0.000 (p = <0.05). Conclusion: The expression of BMP4 and FGF2 increased after the application of collagen extract from gourami scales.

Abstract

Background: After tooth extraction, alveolar bone resorption occurs naturally, followed by alveolar bone remodeling. Alveolar bone formation is characterized by an increase in density and expansion of the trabecular bone. Socket preservation using a combination of Moringa oleifera leaf extract and demineralized freeze-dried bovine bone xenograft (DFDBBX) is expected to increase the area of the alveolar bone trabeculae and thus accelerate the process of alveolar bone formation. Purpose: This study aimed to determine if a combination of Moringa oleifera leaf extract and DFDBBX could increase the area of the alveolar bone trabeculae in tooth extraction sockets. Methods: With their lower left incisors extracted, the 56 Cavia cobayas were divided into eight treatment groups according to the material given: polyethylene glycol (PEG), DFDBBX and PEG, Moringa oleifera leaf extract and PEG, and a combination of Moringa oleifera leaf extract, DFDBBX, and PEG. On the seventh and thirtieth days, the Cavia cobayas were sacrificed and examined. Histopathological samples were stained with Hematoxylin-Eosin (HE) to evaluate the trabecula area, and data were analyzed using one-way ANOVA and Tukey HSD. Results: On the thirtieth day, the group that received a combination of Moringa oleifera leaf extract and DFDBBX had the greatest area of alveolar bone trabeculae. Conclusion: A combination of Moringa oleifera leaf extract and DFDBBX induced in the tooth extraction socket can increase the area of the alveolar bone trabeculae.

Abstract

Background: The persistence of microorganisms in the root canal system is one of the leading causes of root canal treatment failure. Biofilms of putative pathogens hidden inside dentin tubules and other root canal ramifications may limit current disinfection protocols. Photodynamic therapy (PDT) with a wavelength of 628 nm can be used as an antimicrobial strategy that uses low-power laser energy to activate a non-toxic photosensitizer to produce singlet oxygen with the ability to kill microorganisms in root canals. Fusobacterium nucleatum was used because this bacterium is one of the bacteria involved in root canal infection. Purpose: The aim of this study was to compare the bactericidal efficacy of sodium hypochlorite (NaOCl) 2.5%, PDT, and a combination of PDT and NaOCl 2.5% against Fusobacterium nucleatum. Methods: Mature biofilm Fusobacterium nucleatum was divided into four groups according to the protocol of decontamination: K1 (negative control – biofilm), K2 (NaOCl 2.5%), K3 (PDT), and K4 (NaOCl 2.5% + PDT). Biofilm degradation was observed using optical density (OD) at 570 nm using a microplate reader. A reactive oxygen species quantity check was carried out using a nitroblue tetrazolium test, and OD observation was done with a microplate reader at 540 nm. Results: Group 4 (NaOCl 2.5% + PDT) showed more biofilm bacteria elimination than the other groups. Conclusion: A combination of PDT and NaOCl 2.5% can be considered an effective protocol for the elimination of Fusobacterium nucleatum. There is a potentiation relationship between NaOCl 2.5% and PDT FotoSan. Biofilm degradation occurs because of the effect of antibacterial NaOCl 2.5% and the irradiation effect of the Toluidine blue O photosensitizer.

Abstract

Background: The cause of cavities is initially due to roughness on the tooth surface, requiring fluoride varnish to prevent caries, as the varnish applies a fluoride compound to the tooth surface. Fluoride varnish reacts with the tooth enamel surface to form calcium fluoride and fluorapatite, thus making the enamel surface more resistant to demineralization and damage. Purpose: This study aims to compare the roughness of tooth enamel surfaces among three fluoride varnishes under acidic conditions. Methods: The research method uses three fluoride varnish materials: sodium fluoride 5% + tricalcium phosphate, calcium fluoride, and sodium fluoride 5% + casein phosphopeptide-amorphous calcium phosphate 2%. Samples of 81 teeth were divided into three groups (Group 1 without fluoride varnish application, Group 2 application of fluoride varnish with pH 3, and Group 3 application of fluoride varnish with pH 5). The teeth were tested before and after application of the varnishes using the scanning electron microscope and surface roughness tests. Results: The results showed a significant difference in the mean surface roughness of the enamel of the anterior deciduous teeth tested with fluoride varnish. The before and after comparisons in the pH 3 and pH 5 groups were very significant (p-value 0.000). The comparison results in each pH group after fluoride varnish administration showed no significant difference (pH 3 p-value 0.074 and pH 5 p-value 0.196). The tooth surfaces appear to be rougher after administration of an all-acid solution. Conclusion: There is a difference in surface roughness of primary teeth after being given fluoride varnish in low pH 3 immersion for 24 hours.

Abstract

Background: The intricate process of tooth formation during embryonic development ensures sufficient nutrition for the growth of healthy dental tissues. Amelogenin and alkaline phosphatase (ALP) are serine proteinases secreted by the ameloblast during the transition and maturation phases of the amelogenesis process. Consumption of saltwater fish is predicted to increase the expression of amelogenin and ALP in ameloblast cells during tooth formation. Only now have the function of each gene, tooth-forming cells, and the proteins they produce in the biomolecular amelogenesis of tooth enamel, which began during prenatal development, been clarified. Purpose: This study aims to determine how saltwater fish powder affects the ability of mother mice to increase the expression of amelogenin and ALP in cell ameloblast. Methods: Using a completely randomized design, this study was experimental and aimed to examine the effects of sardine (Sardinella fimbriata), splendid ponyfish (Leiognathus splendens), and tuna (Euthynnus affinis) powder. As samples, twenty-four female mice (Mus musculus) were used. Two groups of mice were created: group 1 (2.14 mg/0.5 ml) and the control group. The expression of amelogenin and ALP was determined using immunohistochemistry (IHC) and t-test (p0.05). Results: Expression of ameloblast was significantly different between the treatment and control groups (p0.05). Conclusion: The consumption of saltwater fish reduces the amelogenin and ALP expressions of mouse fetal ameloblast cells during tooth development in vivo.

Abstract

Background: Jaw fracture is the most common facial fracture in oral and maxillofacial bone and is usually caused by trauma. The fracture itself could lead to infection due to bone and tissue damage, which is the port of entry for microorganisms. Fracture-related infection (FRI) in the patient discussed in this study manifested as a submandibular abscess. The goals of fracture treatment were achieving the anatomic reduction of the fracture line and regaining acceptable occlusion. There are two methods for treating mandibular fractures: the closed method, also called conservative treatment, and the open method, which requires advanced surgery. Closed method treatment uses a maxillomandibular fixation (MMF) device in order to reduce and immobilize fracture fragments. Treatment of FRI should use a multidisciplinary approach to achieve an outstanding result, such as wound debridement, antimicrobial therapy, and implant retention. Purpose: The purpose of this article is to report a case of neglected mandibular fracture with a submandibular abscess, which was treated with a combination of the closed reduction method and incision drainage. Case: A 25-year-old female visited Nala Husada Hospital because of a submandibular abscess on the neglected mandibular fracture of the right parasymphysis and left corpus. Case management: The case was managed using an arch bar in the mandible and an eyelet in the maxilla while continuing with MMF and an extra oral drainage incision. Conclusion: Combination therapy (MMF and incision drainage) was needed to treat this case because of the occurrence of a submandibular abscess due to a neglected mandibular fracture.

Abstract

Background: The use of a bone graft in bone regeneration is challenging. Tooth graft material has been used as a bone graft alternative due to its similar composition of organic and inorganic materials close to the bone. Recently, nanotechnology has been used to improve bone graft quality. The osteoconduction rate in the defect area represents the bone graft quality. Purpose: This study aimed to compare the number of osteoblasts using nano-tooth grafts and micro-tooth grafts in Wistar rats. Methods: Wistar rats were divided into six groups: the negative control groups (examined on days 7 and 14), the micro-tooth graft groups (examined on days 7 and 14), and the nano-tooth graft groups (examined on days 7 and 14). The control group received nothing, the micro-tooth group received a micro-size tooth graft, and the nano-tooth graft group received a nano-size tooth graft on the injured femur. Histological observations of osteoblasts were carried out using a light microscope with 1000x magnification. Data were analyzed using one-way analysis of variance and least significant difference tests. Results: On day 7, the nano-tooth graft group showed a higher osteoblast number (11.75) than the micro-tooth graft group (7.5) (p = 0.039). There was no significant difference in the micro-tooth graft group compared to the control (p > 0.05). On day 14, the nano-tooth graft group showed a decrease in osteoblast number close to normal (control) (p > 0.05), while the micro-tooth graft group still experienced significant elevation. Conclusion: Nano-tooth grafts accelerate the stimulation of osteoblasts in the first stages of the healing process compared to micro-tooth grafts.

Abstract

Background: A good biocomposite is a structure that can provide opportunities for cells to adhere, proliferate, and differentiate. It is affected by the characteristics of a material. As bone tissue regeneration occurs, biomaterials must have a high swelling ability and low biodegradability. The high swelling capability will have a larger surface area that can support maximal cell attachment and proliferation on the biocomposite surface, which accelerates the regeneration process of bone defects. Purpose: The study aimed to analyze the characteristics of swelling and biodegradation of bovine amniotic membrane-hydroxyapatite (BAM-HA) biocomposite with various ratios. Methods: The BAM-HA biocomposite with a ratio of 30:70, 35:65, and 40:60 (w/w) was synthesized using a freeze-dry method. The swelling test was done by measuring the initial weight and final weight after being soaked in phosphate-buffered saline for 24 hours and the biodegradation test was done by measuring the initial weight and final weight after being soaked in simulated body fluid for seven days. Results: The swelling percentage of BAM-HA biocomposite at each ratio of 30:70, 35:65, and 40:60 (w/w) was 303.90%, 477.94%, and 574.19%. The biodegradation percentage of BAM-HA biocomposite at each ratio of 30:70, 35:65, and 40:60 was 9.43%, 11.05%, and 12.02%. Conclusion: The BAM-HA biocomposite with a ratio of 40:60 (w/w) has the highest swelling percentage while the 30:70 (w/w) ratio has the lowest percentage of biodegradation.

Abstract

Background: One of the main components in tissue engineering is the scaffold, which may serve as a medium to support cell and tissue growth. Scaffolds must have good compressive strength and controlled biodegradability to show biological activities while treating bone defects. This study uses Chitosan-gelatin (C–G) with good flexibility and elasticity and high-strength carbonate hydroxyapatite (CHA), which may be the ideal scaffold for tissue engineering. Purpose: To analyze the compressive strength and static biodegradation rate within various ratios of C–G and CHA (C–G:CHA) scaffold as a requirement for bone tissue engineering. Methods: The scaffold is synthesized from C–G:CHA with three ratio variations, which are 40:60, 30:70, and 20:80 (weight for weight [w/w]), made with a freeze-drying method. The compressive strengths are then tested. The biodegradation rate is tested by soaking the scaffold in simulated body fluid for 1, 3, 7, 14, and 21 days. Data are analyzed with a one-way ANOVA parametric test. Results: The compressive strength of each ratio of C–G:CHA scaffold 40:60 (w/w), 30:70 (w/w), and 20:80 (w/w), consecutively, are 4.2 Megapascals (MPa), 3.3 MPa, 2.2 MPa, and there are no significant differences with the p= 0.069 (p>0.05). The static biodegradation percentage after 21 days on each ratio variation of C–G:CHA scaffold 40:60 (w/w), 30:70 (w/w), and 20:80 (w/w) is 25.98%, 24.67%, and 20.64%. One-way ANOVA Welch test shows the result of the p-value as p<0.05. Conclusion: The compressive strength and static biodegradation of the C–G:CHA scaffold with ratio variations of 40:60 (w/w), 30:70 (w/w), and 20:80(w/w) fulfilled the requirements as a scaffold for bone tissue engineering.
