Several congenital and acquired defects require alloplastic restorations. These kinds of prosthesis may be retained and supported by osseointegrated implants, the remaining skin with or without adhesive and body cavities. Extraoral maxillofacial prosthesis are primarily fabricated using silicone. Obtaining a reliable and reproducible coloration technique is important in the process of fabrication. The present study is to study the development of and advancements in intrinsic staining techniques of silicone prosthesis. The authors reviewed literature and summarized the different colouration techniques for intrinsic staining previously and presently used for maxillofacial silicone prosthesis from published research available in the Dental Library of the University of Malaya and different databases: Science Direct, PubMed and Web of Science. There are diverse methods to intrinsically match the colour of facial skin in maxillofacial prosthetics. Newer methods used in coloration have produced more accurate colour matching and have proven to be less time-consuming.

Background: Most undergraduate dental students were concerned regarding the transmission of the COVID-19 virus through their profession. This dread and anxiety may be attributable to a lack of comprehension regarding the necessary precautions and protocols to implement to ensure safety and limit potential infection threat. This study aims to assess COVID-19-related knowledge, attitudes, and practices (KAP) among undergraduate dental students at the Faculty of Dentistry, Universiti Malaya. Methods: A cross-sectional study design was used, involving 166 respondents who were undergraduate dental students from years II to IV. Data collection was achieved using a pre-tested web-based questionnaire. Descriptive and inferential analyses, including independent t-tests and one-way analysis of variance (ANOVA) tests, evaluated the KAP differences related to demographic factors. Results: There were no statistically significant differences in mean KAP associated with demographic factors such as gender, place of residence, and year of study (p > 0.05). Conclusions Dental students at the Faculty of Dentistry, Universiti Malaya, Malaysia, had adequate knowledge of COVID-19 in light of the country’s quarantine status and pandemic context.
