In this article, we will introduce the basic science of how oral surgery lights are used in dental practice. There are several different light sources used throughout the practice and all of them have certain purposes and characteristics. During the surgery, lighting has two functions: task lighting and ambient lighting. Ideally, for the rest of the practice, brightness should still be a consideration, depending on the environment. Understanding the possibilities and solutions is critical to achieving the best results for lighting and the improvements it brings. Regarding the contrast light source for dental surgery, most dentists must adjust their vision to cope with the lighting conditions produced by surgical lights and ceiling lighting. As we age, our vision will gradually deteriorate, which means our eyes need more light to see the same degree. Eye fatigue, fatigue, headache and environmental stress are common diseases, as well as neck and back strain. All of this can be prevented with optimal illumination settings to minimize strain risk while ensuring the most favorable patient’s oral vision. Contact our designers for advice or review your current lighting settings. The proper dental lighting should strike a balance between providing high-intensity illumination to improve work accuracy, especially when repairing and color matching procedures such as beauty work, as well as reducing eye strain and increasing energy levels, because light can affect how tired You feel at the end of the day. Therefore, it is very important to select a suitable dental LED oral light during a dental procedure.
