2023-03-17T05:17:45+00:00

Background: Bone loss has a major impact on the process of placing implants and dentures. Nanoparticle hydroxyapatite (HANP) has better biodegradability and mechanical properties than micro-particle hydroxyapatite. PVA is a synthetic polymer that is cheap, hydrophilic, has high mechanical stability and flexibility but low biodegradability. PLGA is a new synthetic polymer which is widely used in the biomedical, however PLGA has less osteoconductive properties. The ideal scaffold has several important characteristics, one of which is having a porosity of>70%. Objective: To know the role of PLGA on the porosity of the scaffold by comparing the porosity of the HANP-PVA scaffold and the HANP-PVA scaffold given PLGA Methods: Group 1 was the HANP-PVA scaffold with a content of 20% HANP (w / w). Group 2 was the HANP-PVA scaffold which added 20% (w/w) of PLGA. Both groups were synthesized by freeze drying method at -80^oC for 24 hours. The porosity test was used the liquid displacement method for 24 hours. Statistical testing using Shapiro Wilk, Levene's test and Independent t-Test Results: The porosity of the HANP-PVA scaffold was 77.90% ± 4.51 and the HANP-PVA-PLGA scaffold was 87.55% ± 5.67. The Shapiro-Wilk normality test showed that the data were normally distributed (p> 0.05). The independent t test showed a significant difference between the HANP-PVA and HANP-PVA-PLGA scaffold (p <0.05) Conclusions: The addition of PLGA to the scaffold can increase the porosity of the HANP-PVA scaffold. HANP-PVA-PLGA has the potential to accelerate bone regeneration after extraction

EFFECT OF LIME PEEL EXTRACT (Citrus aurantifolia Swingle) NANOTRANSFERSOME GEL ON THE MMP-9 EXPRESSIONS ON WISTAR RATS ULCER WOUND HEALING

2023-01-25T06:57:36+00:00

Background: Traumatic ulcers are generally caused by physical, chemical, or thermal trauma. When an ulcer occurs, wound healing processes such as hemostasis, inflammation, proliferation, and remodeling occur. In the wound healing process, the expression level of matrix metalloproteinase-9 (MMP-9) must be tightly controlled because increased expression of MMP-9 can delay wound healing by degrading the extracellular matrix (ECM) and collagen uncontrollably. Nanotransfersome gel of lime peel extract (Citrus aurantifolia Swingle) contains flavonoids, tannins, saponins, and alkaloids which have anti-inflammatory properties and can accelerate the wound healing process. Nanotransfersomes can improve tissue localization and minimize excessive drug release. Purpose: This study aims to determine the effect of lime peel extract nanotransfersome gel on the expression of MMP-9 on wound healing of wistar rats ulcers. Methods: This study used 4 groups of wistar rats with time series on days 3 and 7, namely the control group, the treatment group given lime peel extract, the treatment group given lime peel extract nanotransfersome gel, and the treatment group given standardized herbal medicine. Observation of the MMP-9 using 400x magnification. Result: Data analysis using One Way Anova test showed that there were significant differences in MMP-9 expression in the treatment groups K7 with P7B and P7A with P7B. Conclusion: Based on the results of the study it can be concluded that lime extract nanotransfersome gel can reduce MMP-9 expression in wound healing of wistar rats ulcers.

RELAPSE MOVEMENT AFTER ORTHODONTIC TREATMENT

2023-04-05T08:12:05+00:00

Introduction: Orthodontic treatment is one of treatment in the field of dentistry by moving the teeth to correct malocclusion and malposition of the teeth. After treatment is complete, there is still the possibility of relapse, which is the process of moving the teeth to their original position before orthodontic treatment. It is still a complex problem after the end of orthodontic treatment. Objective: This literature review aims to examine the process and mechanism of relapse so that it can be additional information in efforts to prevent relapse. Discussion: Relapse can occur due to various factors and relapse occurs rapidly on day 1 to day 24 after removal of the orthodontic appliance. Orthodontic tooth movement and relapse movement will show an increase in the number of osteoclasts in areas of stress and a decrease in the number of osteoclasts in areas of tension. This suggests that alveolar bone remodeling is an important element in the process of relapse. Conclusion: Efforts to deal with relapse need to be carried out with various approaches, including pharmacologically which can affect the alveolar bone remodeling process, especially in osteoclast cells which play a role in the process of tooth relapse movement.
