The surface roughness of orthodontic archwires is an essential factor that deter- mines the effectiveness of arch-guided tooth movement. CuNiTi-based wires are widely used in orthodontic treatment, but the oral environment can trigger corrosion of CuNiTi orthodontic wires. The tannin content in avocado seed extract can be used as a corrosion inhibitor through two working mechanisms, namely, forming a passive layer and an adsorption process. The aim of this research is to examine the effect of avocado seed extract as a corrosion inhibitor on the surface roughness of orthodontic CuNiTi wire. The as- retacngular 17 x 25 inch CuNiTi wire were taken in 4 group (1 control group soaked in artificial saliva and 3 treatment groups soaked in avocado seed extract ). Â Samples were immersed in avocado seed extract with concentrations of 1,5 g/L, 2 g/L and 2,5g/L for 7 days. For surface roughness was test Surface Roughness Average analysis. One way ANOVA test showed that there was a significant difference between the control group and all treatment groups in the surface roughness test with a value of p = 0.000. Post Hoc LSD test showed that there were no significant differences between treatment group 2 and treatment group 3 with a p value = 0.122. Providing avocado seed extract with tannin content at concentrations of 1.5 g/L and 2 g/L can reduce surface roughness on CuNiTi wire due to the corrosion process.

Background: Tooth extraction causes injury to the alveolar bone and oral mucosa which is followed by the body â€™s natural response through wound healing. One of the important parameters and indicators of wound healing is collagen density. Collagen is synthesised by fibroblasts in the proliferative phase, which was formed from day 3 and reached its peak on day 7. Robusta coffee beans have active compounds in the form of anti-inflammatory and antioxidants that are effective in accelerating wound healing. Objective: To determine the effectiveness of robusta coffee bean extract gel (Coffea canephora) at concentrations of 12,5%, 25%, and 50% in increasing the thickness of collagen fibres in socket wound healing after tooth extraction in Wistar rats. Method: This type of research is laboratory experimental. The samples used were 40 male Wistar rats divided into 5 groups: negative control, positive control, 12.5% robusta coffee bean extract gel treatment, 25% robusta coffee bean extract gel treatment, and 50% robusta coffee bean extract gel treatment. The sample group was decapitated on the 3rd and 7th day after tooth extraction. Socket tissues were taken to make histological preparations stained with trichrome mallory and then measured using Adobe Photoshop CS 6.0 software. Results: The average thickness of collagen fibres in the Robusta coffee bean extract gel treatment group was higher than that in the control group (p

The release of ions is the initial stage of the corrosion process in an orthodontic wire. Continuous release of ions can reduce the effectiveness and performance of the orthodontic wire. Continuous release of ions in CuNiTi orthodontic wire can change the properties of the wire and trigger hypersensitivity reactions, also in stainless steel orthodontic wire which experiences continuous release of ions can reduce its stiffness. The tannin in avocado seeds is useful as a corrosion inhibitor it can inhibit the release of ions because they are able to bind with metal ions and form a passive layer also able to bind with Fe ions in stainless steel orthodontic wires to form a passive surface layer which is able to inhibit the release of ions when the corrosion process occurs. The aim of this research is to determine the effect of avocado seed extract as a corrosion inhibitor on the release of metal ions from CuNiTi and stainless steel orthodontic wires. Rectangular CuNiTi and stainless steel orthodontic wires measuring 0.017 x 0.025 inches were taken in 3 groups (1 control group soaked in artificial saliva and 2 treatment groups soaked in avocado seed extract). The samples were soaked in avocado seed extract with a concentration of 1.5 g/L and 2 g/L for 7 days. To see the release of ions, an X-Ray Fluorescence test is carried out. In CuNiTi orthodontic wire from the one way ANOVA test showed that there was a significant difference between the control group and all treatment groups on Cu, Ni and Ti ions. The Post Hoc LSD test showed that there were significant differences between the control group, treatment group 1 and treatment group 2 in Cu, Ni and Ti ions with a p value. In stainless steel orthodontic wire, the one way ANOVA test showed that there was a significant difference between the control group and all treatment groups in Fe and Ni ions but not significant in Cr ions in the ion release test with a p value <0.05. The Post Hoc LSD test showed that there were significant differences between the control group, treatment group 1 and treatment group 2 in Fe and Ni ions with a p value <0.05. Providing avocado seed extract with tannin content at concentrations of 1.5 g/L and 2 g/L can inhibit the rate of ion release in CuNiTi and stainless steel orthodontic wires due to the corrosion process.
