Lumoral oral health case study

Lumoral utilises Koite’s unique patented photodynamic treatment technology, the result of many years research and trials.
RDD was involved in supporting the development of this medical level product from initial concept through to tooling and volume production. Utilising the skills across a number of disciplines and skill sets, including research, ergonomics, engineering innovation, industrial design, DFM, prototyping and testing, conformance and certification, tooling, factory implementation and quality assurance.

From leading innovation in dental hygiene Lumoral is based on significant advancements is photodynamic treatments, developed through research, trials and testing.
RDD+ worked in partnership with Koite to develop a new dental hygiene device, taking advantage of innovation in photo dynamic technology to create a consumer product.  Photodynamic treatment delivers advances oral hygiene and health benefits.
Patented Technology – Lumoral® provide patented dual-light PDT. Dual-light PDT has shown excellent antibacterial properties in repeated use without resistance formation.
How does it work – The system works by using a specially formulated mouthwash, Lumorinse, followed by applying the patented Lumarol light via the mouthpiece.  Lumarinse is supplied in the form of solvable tablets that create the photosensitive mouthwash
What does it do – Even after a single use of Lumoral, one can feel the teeth increased smoothness as Lumoral antibacterial action removes the microscopic biofilm from the teeth surface.

Healthcare advantages
The most difficult problems in dentistry are caused by tooth decay or periodontitis (long-term inflammation of the gingival tissue). These diseases are caused by bacterial biofilms.
Lumoral helps to manage biofilm bacteria. Gingival disorders are associated with the development of several chronic conditions such as, cardiovascular disease, chronic lung disease, rheumatism and diabetes. Lumoral method improves oral hygiene and can eliminate bacteria, the ultimate goal is to improve overall health.
Lumarol device enables regular use, and it can be used not only in the dental clinic but also at home. Lumorinse has been developed to easily attach to dental plaque,  the antibacterial effect can be targeted to the desired areas.
The interaction between Lumoral’s photodynamic therapy and antibacterial blue light has been shown to be very effective against harmful oral bacteria.

User insight
RDD+ selected specifically to drive the integration of innovation, technology and chemistry into a consumer product –  taking a lab concept to commercial proposition.
User research and testing was key to success. In early trials the product form factor was a LED wand rather than the mouthpiece of the final design.  Consumer insight and user trials help to inform the design direction and move to the mouthpiece design.
The design direction was hugely influenced by ergonomic factors, performance and the specific product use case.  Medical performance, hygiene and durability were all key factors in developing a successful product.
From the project outset the key challenge was to build a market leading product to deliver all the health benefits developed in research .
Design and development
The product design is driven by aligning the technical innovation and advantages found through research with user needs and the focus required to create a successful consumer product.
The Lumoral system is created by several elements – mouthpiece, controller, power pack, Lumorise tablets. 
The mouthpiece and controller design…what are the requirements
The power pack is designed to deliver X hrs power to the mouthpiece to provide x days between charges.
