Background: Dental X-ray has an important role in dentistry. Complication case such as tooth fracture extraction requires this examination to determine the appropriate treatment measures. Dental X-ray can also cause a negative impact to the body at cellular and even molecular level. Purpose: The aim of this study was to evaluate the decrease of vascular endothelial growth factor (VEGF) expression and new blood vessels number caused by dental X-ray irradiation on fractured tooth extraction wound on day 3 and 7 after extraction. Method: We used 30 wistar rats which was randomly divided into 6 groups. Each rat's central insisive of left mandible was fractured and then extracted after or without X-ray irradiation. Group KA and KB were control groups without irradiation. Group P1 A and P1 B were treatment groups with 0.08 mSv irradiation dose. Group P2 A and P2 B were treatment groups with 0.16 mSv irradiation dose. The subject from group KA, P1 A, and P2 A were sacrficed and sockets were collected at day 3. The subject from group KB, P1 B, and P2 B were sacrficed and sockets were collected at day 7. Socket were processed and painted with hematoxylin eosin and immunohistochemistry, then observed with a microscope. Data processing was performed with SPSS 16 through one way anova test and post hoc Tukey test HS. Result: The lowest means expression of VEGF and the number of new blood vessels on the day 3 was found in P2 A group, and the highest found in the KA group. The lowest means expression of VEGF and the number of new blood vessels on the day 7 was found in P2 B group, and the highest found in the KB group. Conclusion: Dental X-ray irradiation dose of 0.08 mSv and 0.16 mSv causes decrease of VEGF expression and new blood vessels in the wound fractured tooth extraction in day 3 and day 7 post-extraction.

Background: Heat-cured acrylic resin is a material that is often used for the manufacture of removable partial dentures in dentistry because it uses simple equipment, relatively inexpensive, and is easy to repair. Acrylic resin also has a disadvantage, such as the low value of flexural strength so that it can cause the denture to fracture. This study determine the effect of non-dental glass fiber volume fraction on the flexural strength of heat cured acrylic resin. Method: This research are post-test only control group design. Acrylic resins were divided into four groups (6 sample each group), group 1 without the addition of non-dental glass fiber or 0% and heat cured acrylic resin group with the addition of non-dental glass fiber 1%, 2%, and 3% (group 2, 3 and 4). Result: The average flexural strength of acrylic resin with a volume fraction of 2% of non-dental glass fiber had the highest value compared to other groups. The results of the Mann-Whitney test from several test groups showed significant differences in the value of flexural strength from each group (p<0.05), except for the 0% and 3% group. Conclusion:There is an effect of volume fraction of non-dental glass fiber on the flexural strength of heat cured acrylic resin.
Introduction: Forensic odontology is a branch of dentistry that has disciplines learn about the examination of evidence derived from teeth, and how to deal with the evidence for legal concerns. Purpose: The aim of the study was to describe biological age estimates by using Kvaal method in Semarang, and the difference between biological and chronological age by using the Kvaal method in Semarang. This study was descriptive with crosssectional design. Materials and Methods: One of the methods in determining the estimated age by using teeth is the Kvaal method. Kvaal method determines the estimated age based on the pulp size using radiography. Result: The results showed the difference between biological and chronological age was ±4,57 years. This result is lower than Kvaal’s previous study result which was ±9,5 years. Conclusion: Based in the findings above, it can be concluded that the difference of chronological and biological age using Kvaal method in Semarang was ±4,57 years within 15-60 years old individuals in Semarang.
Background: Cancer is the second leading cause of death in the world after heart disease. One type of cancer, namely head and neck cancer, can be treated with head and neck radiotherapy. Continuous radiotherapy will cause an increase in oxidative stress and free radicals and damage to the oral mucosa, one of which is oral mucositis. Giving ozone water can help reduce the degree of oral mucositis in patients. Ozone water itself has several beneficial effects such as antioxidant, anti-inflammatory, and antimicrobial. The purpose of this study was to determine the potential of ozone water in reducing the severity of oral mucositis in patients after head and neck radiotherapy.Method: Gargling treatment using ozone water in a ratio of 2:3 for 1 minute with 4 repetitions for 2 weeks showed a significant reduction in pain. Ozone used in gas or liquid form for more than 5 minutes has the potential to cause side effects on the duration of inflammation and for gas can cause infection in the respiratory tract.Conclusion: The conclusion of this review is that the administration of ozone water with a concentration of 2-4 ppm for approximately 5 minutes has the potential to cure oral mucositis due to head and neck radiotherapy
