The Faculty of Dentistry of the University of Hong Kong (HKU) organised an online session “A glimpse of Dentistry: Science and Art and Technology” during the HKU “Week of Taster” from April 11 to 15 to give secondary school students a taste of HKU’s programmes, where secondary 2 to 4 students used their creativity to make molar models out of clay.
The online learning session held on April 13 consisted of three parts and was moderated by Dr Mike Leung, Admissions Tutor cum Assistant Dean (External Relations).
The first part was about science – dental radiology with a tutorial introducing the use of radiology in dentistry and demonstrating various dental X-rays. Students learned how to read the X-ray – distinguish whether it is the patient’s left or right side, and upper or lower jaw and if the patient is a child or an adult; and whether they are suffering from tooth decay, periodontal disease or jaw cysts. At the end of the session, there was an online quiz to test the students’ understanding of dental radiology.
The second part was about technology – 3D Printing in Dentistry. Dr Mike Leung explained the conventional method of creating dental dentures, crowns, teeth, etc. He also introduced how the latest 3D printing technology assists in manufacturing dental restorations and its application in dental implant placement and oral and maxillofacial surgery. He highlighted the micro-mist mouthguard cleaning device designed by Dr James Tsoi, Associate Professor in Dental Materials Science, that can help elderly people clean their teeth.
The last part was about art. A video on crafting a molar step by step from the clay was shown. The students then had the chance to create one by themselves with the materials provided.
"Much like art, dentistry requires manual dexterity and an eye for beauty, as dentists work to restore teeth and correct facial structure so that patients can restore their beautiful smiles," said Dr Leung.
Dr Leung thanked the students for their participation, and said: "Dentists do not just extract teeth, scale, or fill cavities. They are medical professionals who serve the public by treating dental problems, correcting jaw deformities and educating them about oral disease prevention. They shape the future of oral health care by advancing dental education, research, and technology. I hope to see you all in HKU in the near future!"
The HKU Taster event was held in April, where academics from the ten faculties gave lectures on a number of popular topics to students from Secondary 2 to 4, giving them a taste of the University's diverse curriculum online.
The following are the best 10 submissions of the molar model:
香港大學（港大）牙醫學院於4月11日至15日HKU Taster「港大課程體驗週」期間，舉辦了 「牙科一瞥: 科學、藝術與科技」網上學習課程，讓中二至中四的學生利用黏土製作牙齒模型，發揮想像和創作力。
學院的網上課程於4月13日舉行，分為三個部分，由新生遴選委員兼助理院長（對外事務）梁耀殷醫生主持。
第一部分是科學 – 牙齒放射學，介紹放射學在牙醫診治上的應用，如何看懂各種牙齒X光片，例如區分口腔的左側或右側、上顎或下顎、患者是小孩還是成人，以及是否患有蛀牙、牙周病或下顎囊腫等口腔疾病。此部份完結設有線上測驗，測試學生對牙齒放射學的理解。
第二部分是牙科科技 – 3D打印技術。梁醫生闡述假牙、牙冠、牙齒等的傳統製作方式，並講解製造牙齒修復和植牙裝置的最新3D打印技術，以及該技術在口腔頜面外科手術的應用。他特別介紹了由學院研發，專門為長者和殘疾人士而設，以3D打印技術製造的微霧噴射口部清潔裝置 。
第三部份是牙科藝術。參與的同學按著示範影片，發揮創造力，自己動手用黏土製作臼齒模型。
「牙醫像藝術家，他們要有靈巧的雙手和審美能力，以修復患者的牙齒和下頜結構，讓他們恢復美麗的牙齒和笑容。」梁醫生說。
梁醫生感謝同學參與，他説：「牙醫不只做拔牙、洗牙、填補蛀牙和矯正下顎畸形等的牙科治療。他們是醫療專業人士，有責任教育大眾預防口腔疾病，推動牙科教育、研究和科技的發展，任重而道遠。期望在不久的將來，與大家在港大見！」
香港大學（港大）於4月舉辦HKU Taster活動，來自十個學院的老師，淺入深講解多個熱門話題，讓中二至中四的學生能足不出戶學習各種趣味知識，於網上體驗大學多姿多彩的課程。
