Abstract:

The application of light-emitting diodes (LEDs) has evolved, and its use has been incorporated into different sciences, one of which is dentistry. The objective is to propose a solution of LED semiconductors based on the engineering of LED circuits to formulate a prototype of a third-generation light curing unit with adequate energy efficiency, within the electromagnetic spectrum of blue-violet light to carry out an effective light-curing of resin-based restorative materials; also, a long working life, innovative design and low cost. To collect data on the daily clinical practice and use of LED light curing units, a survey was conducted with 32 health professionals in the dental field (among dentists, bachelors in Dentistry and dental students). According to the data obtained, together with the theoretical information, this research describes the proposal for the design of an arrangement of LED semiconductors - plate of 5 miniature Blue-Violet chips (Packing of LEDs - OSTAR LIGTHNG) to be considered for the implementation in the dental field, in order to propose a prototype of a more efficient LED light curing unit, with lower costs and that meets the conditions expected by dental professionals. It is concluded that the engineering associated with the technological evolution of LEDs can contribute to the improvement of equipment, systems, and devices used in dental treatments.
