Abstract

Background: Osteoporosis is a systemic disease that can decrease bone density as a result of imbalance bone remodeling and bone resorption. Estrogen reduction due to menopause can increase osteoclast activity and furthermore decrease bone density. Estrogen can stimulate alkaline phosphatase (ALP) expression, collagen type I and osteocalcin in bone remodelling process. Ovariectomized rat is a common animal for studying patofisiology, diagnosis and treatment osteoporosis patient. Purpose: To evaluate correlation between estrogen and ALP expression in osteoporotic rat model mandible. Methode: 18 female wistar rats, 2 months old, 200 grams were divided into 2 groups, ovariectomized group and sham surgery as control group. Surgery was done under intra muskular anesthesia using combination 2% xylazine 1cc and 10% ketamine 1cc. After 12 weeks, mandible was taken for ALP examination and blood from heart was taken to evaluate the amount of estrogen. Result: There was significant correlation between estrogen and ALP expression in osteoporotic rat model mandible. Conclusion: The amount of estrogen can influence ALP expression activity.

Abstract

Background: Accumulation of denture plaque can lead to pathological changes in oral mucosa, such as denture stomatitis, halitosis, and caries. Plaque matrix is mostly formed by protein (30%) and polysaccharide complexes. Thus, an alternative enzyme solution as denture cleanser is required for hydrolysis of denture plaque. Papain is a proteolytic enzyme hydrolyzing proteins, while β-1,3-glucanase is a hydrolase enzyme hydrolyzing polysaccharides. Purpose: This study aimed to analyze the differences of effectiveness of ß-1,3- glucanase Vigna unguiculata enzyme and papain Carica papaya enzyme in hydrolysis of denture plaque. Method: This research was a laboratory experimental research with post test only control group design. After using denture for 24 hours, the denture was soaked in a solution of 100 ml PBS, papain enzyme, and β 1-3 glucanase enzyme at a concentration of 0.5 mg/ml, 1 mg/ml, and 2 mg/ml for 10 minutes. The solution from plaque hydrolysis was soaked in PBS and vortex enzyme for 2 minutes, then soaked in ice water for 15 minutes, and centrifuged at 3000 rpm 5-10º for 10 minutes. The supernatant was separated and analyzed. Turbidity readings then were performed in spectrofotometer with a wavelength of 480 nm. Result: 2 mg/ml of ß-1,3 glucanase enzyme generated the highest values of hydrolysis with a mean percentage of 68.77% compared to papain enzyme (44.86 %). The lowest values of hydrolysis weregenerated by PBS with a mean percentage of 3.24%. Conclusion: ß-1,3-glucanase enzyme is more effective in hydrolysis of denture plaque than papain enzyme.

Abstract

Background: Various materials have been used for treating dental caries. Dental caries is a disease that attacks hard tissues of the teeth. The initial phase of caries is a formation of bacterial biofilm, called as dental plaque. Dental restorative materials are expected for preventing secondary caries formation initiated by dental plaque. Initial bacterial adhesion is assumed to be an important stage of dental plaque formation. Bacteria that recognize the receptor for binding to the pellicle on tooth surface are known as initial bacterial colonies. One of the bacteria that plays a role in the early stage of dental plaque formation is Streptococcus mutans (S. mutans). Artificial mouth system (AMS) used in bacterial biofilm research on the oral cavity provides the real condition of oral cavity and continous and intermittent supply of nutrients for bacteria. Purpose: This study aimed to compare the profile of S. mutans bacterial adhesion as the primary etiologic agent for dental caries between using static method and using artificial mouth system, a dinamic. method (AMS). Method: The study was conducted at Faculty of Dentistry and Integrated Research and testing laboratory (LPPT) in Universitas Gadjah Mada from April to August 2015. Composite resin was used as the subject of this research. Twelve composite resins with a diameter of 5 mm and a width of 2 mm were divided into two groups, namely group using static method and group using dynamic method. Static method was performed by submerging the samples into a 100µl suspension of 1.5 x 108 CFU/ml S. mutans and 200µl BHI broth. Meanwhile AMS method was carried out by placing the samples at the AMS tube drained with 20 drops/minute of bacterial suspension and sterile aquadest. After 72 hours, five samples from each group were calculated for their biofilm mass using 1% crystal violet and read by a spectrofotometer with a wavelength of 570 nm. Meanwhile, one sample from each group was taken for its surface image using Scanning Electron Microscope (SEM). Result: The results showed that S. mutans biofilm mass in the group using static method was 0.34, while in the group using AMS method was 0.09. The results of the statistical analysis then showed that there was a significant difference (p=0.02) in the formation of bacterial biofilm mass between those groups. SEM image in the group using static method also showed that the attachment of S. mutans was more numerous and had a longer chain than in the group using AMS method. Conclusion: There is a difference in the profile of S. mutans bacterial adhesion between using AMS method and static method.

Abstract

Background: Radiographic examination is often used in dentistry to evaluate tooth extraction complications. X-ray used in radiographic examination, however, has negative effects, including damage to DNA and inflammatory response during wound healing process. Purpose: This study aimed to analyze the effects of X-ray irradiation on transforming growth factor beta 1 (TGF-ß1) expression and number of inflammatory cells in tooth extraction sockets. Method: Thirty rats were divided into three groups, which consist of control group (with a radiation of 0 mSv), treatment group 1 (with a radiation of 0.08 mSv), and treatment group 2 (with a radiation of 0.16 mSv). These rats in each group were sacrificed on days 3 and 5 after treatment. Inflammatory cells which were observed in this research were PMN, macrophages, and lymphocytes. Histopathological and immunohistochemical examinations were used to calculate the number of inflammatory cells and TGF-ß1 expression. Obtained data were analyzed using SPSS 16.0 software with one way ANOVA and Tukey’s HSD tests. Result: There was no significant decrease in the number of PMN. On the other hand, there were significant decreases in the number of macrophages and lymphocytes in the sacrificed group on day-5 with the radiation of 0.16 mSv. Similarly, the most significant decreased expression of TGF-ß1 was found in the group sacrificed on day 5 with the radiation of 0.16 mSv. Conclusion: X-ray irradiation with 0.08 mSv and 0.16 mSv doses can decrease TGF-ß1 expression and number of inflammatory cells in tooth extraction sockets on day 3 and 5 post extraction.

Abstract

Background: Mechanical force of orthodontics causes changes in periodontal ligament vascularization and blood flow, resulting in biochemical and cellular changes as well as changes in the contour of the alveolar bone and in the thickness of the periodontal ligaments. Hyperbaric oxygen (HBO) therapy is one of many solutions stimulating the growth of new blood vessels and increasing tissue oxygenation. Thus, HBO plays a role in recovery of periodontal ligament and osteoblasts. Purpose: This study aimed to determine the effects of HBO therapy for seven days on periodontal ligament size and osteoblast number in the tension site during bone remodeling in tooth movement. Method: The study was true experimental laboratories with completely randomized control group post test only design. Twenty-four males guinea pigs were randomly divided into three groups. K0 was the control group without any treatment, K1 was the group given a mechanical orthodontic pressure, and K2 was the group treated with the addition of hyperbaric oxygen therapy. The maxillary incisors were moved distally by elastic separator. After HBO therapy on day 7, all of the groups were sacrificed, and then periodontal ligament size and osteoblast number were analyzed by one-way Anova and LSD statistical tests. Result: The results showed significant differences in the size of the periodontal ligament and the number of osteoblasts in the tension site among the groups (p<0.05). Conclusion: HBO therapy at 2.4 ATA for 7 days is effective in recovery of periodontal ligament and increased osteoblast number during bone remodeling in tension area of orthodontic tooth movement.
