Dr Kenneth Luk
BDS (Liverpool); DGDP (UK); MGD (CDSHK); MSc (RWTH Aachen); PhD (HKU) Dr. Kenneth Luk obtained his BDS at the University of Liverpool in 1987. He spent the early years of practice in the UK. Dr Luk served as part-time Clinical Lecturer at the University of Hong Kong for over 10 years and has been in private practice since returning to Hong Kong in 1995.
Dr Luk has incorporated lasers in Dentistry since 2002. Furthering the passion in lasers, he obtained the MSc in Lasers in Dentistry at Aachen University, Germany in 2013. In 2021, Dr Luk achieved PhD in laser research at the University of Hong Kong. He is also interested in incorporating lasers in Dental Sleep Medicine.

Dr Luk is currently the secretary of the Asia Pacific Division of WFLD (World Federation for Laser Dentistry). He is active in research and publications in laser dentistry. Dr Luk is the editorial board member of the journal, “Lasers in Dental Science”.

On-line: Use of 445nm blue laser in contemporary dentistry and dental sleep medicine

The use of blue diode wavelength (445nm) has been introduced in the dental market for over 5 years. It is a relatively new laser compared to near infrared (NIR) diode lasers. Clinical applications are similar to NIR lasers. The unique optical property and tissue interaction of this wavelength offers additional clinical applications such as:

• Non ablative melanin depigmentation technique
• An additional wavelength for photobiomodulation
• Management of tissue healing in surgery-combination diode lasers (Blue, red, NIR) approach

Sleep apnoea or sleep disorder is a hot topic that is gaining great attention in medicine. The function of mastication, swallowing and breathing is key to the wellbeing of our health. It is these functions that are related to dental sleep medicine. Tongue and lip tie release by blue laser improve the myofunction for better mastication, maxillofacial development and quality of sleep.
