Background: Facial aesthetic is affected by components that can be observed from the face as a whole (macro-esthetics), and also from the dental components (micro-esthetics). Ideally, the dental midline of a complete denture should coincide with the facial midline of the wearer (i.e. no midline shifting). Among others, one of the main aims of using complete dentures for prosthodontics treatments is to improve facial aesthetic. Consequently, the ability and competency of a dentist to detect midline shifting is vital in order to attain a complete denture with optimal esthetics. In dentistry, the relationship between individual perception of midline shifting and the level of education is often studied. Apart from gender and age, other factors such as the level of education can influence individual’s perception towards midline shifting. The objective of this study is to find out the difference between the perception of pre-clinical and clinical students towards midline shifting in complete dentures. The type of study is cross-sectional observational analytic. Materials and Methods: This study involves 128 pre-clinical and clinical students in FKG Universitas Trisakti. The student’s perception towards midline shifting is measured using 9 photos and a questionnaire. Results: 128 dental students with equal distribution between pre-clinic and clinic students participated in this study. Data analysis showed difference of perception between the two groups (p-value 0.016). Conclusions: There is a significant difference between the perception of pre-clinical and clinical students in FKG Universitas Trisakti towards midline shifting in complete dentures.

Background: Impression material is a material that is used to negatively replicate a patient's tooth structure and periodontal, and it is preferable to sterilize the negative model first before the casting process to avoid cross-contamination between the dentist and the patient. Then casts are made from the impression using type III gypsum, producing diagnostic cast or working cast. Ultraviolet-C (UV-C) sterilization was introduced as the lastest sterilization technology from UV rays with an effectiveness rate of 99.9% in lysing germs, viruses, and fungi. The wavelength of UV-C light itself is also the smallest at 200-270 nm compared to UV-A 320-400nm and UV-B 270-320nm. Objective: To determine the effect of UV-C sterilization on the changes in dimension of alginate impressions. Methods: The type of this research was experimental laboratory research. The samples were taken from the maxillary model which were divided into 2 groups, namely (A) the treatment group where cast was irradiated with UV-C and (B) the control group where casts were sprayed with disinfectant. Samples of the treatment and control groups were both sterilized first before casted. For the treatment group, casts were put in a UV-C box for 10 minutes. For the control group, casts were sprayed with disinfectant, then covered with a moistened tissue and put into a plastic seal. Result: UV-C sterilization did not show significant changes toward dimensional changes of alginate impressions. Conclusion: UV-C sterilization can be used to sterilize alginate impression materials because it does not cause significant dimensional changes of the impression

Background: The denture element is the component that functions to chew food, besides the chewing function it also affects the aesthetics of a person. In the maintenance of denture hygiene, avocado extract can be an option because it has antibacterial and anti-fungal effects, it also has ingredients that can cause discolouration. Purpose: This study aims to determine the effect of soaking time in the avocado seed extract on the discolouration of the acrylic denture elements. Methods: The object of the study was an acrylic denture element with the Naperce brand with colour code A3. The research was conducted by immersing acrylic resin denture elements in aquadest and a solution of avocado seed extract. This study was divided into a treatment group and a control group. In each group 20 ml of fluid. First, the control group was the aqua dest group and the next for the avocado seed extract diet group. Colour measurement using a Spectrophotometry tool with the VITA easy shade V type after immersion at 30, and 45 minutes. The data calculation used the normality test with the Shapiro-Wilk method, the Mann-Whitney test, and the independent T-test. Results: The results obtained from this study showed no significant colour change (p> 0.05). Conclusion: The use of avocado seed extract as a denture-cleaning agent did not provide a significant discolouration of the acrylic denture elements.
