Review
Photobiology is the study of the local and systemic effects of incident radiation on living organisms. Solar radiation is made up of ultraviolet, visible and infrared radiation. Ultraviolet radiation is made up of UV-C, UV-B, and UV-A. Sun exposure can lead to sunburn, tanning, vitamin D production, photoaging, and carcinogenesis. Phototherapy is the use of nonionizing radiation to treat cutaneous disease. Various types of artificial light sources are used for photo testing and phototherapy.

Review
Light is an emerging treatment approach that is being used to treat many diseases and conditions such as pain, inflammation, and wound healing. The light used in dental therapy generally lies in visible and invisible spectral regions. Despite many positive results in the treatment of different conditions, this therapy still faces some skepticism, which has prevented its widespread adoption in clinics. The main reason for this skepticism is the lack of comprehensive information about the molecular, cellular, and tissular mechanisms of action, which underpin the positive effects of phototherapy. However, there is currently promising evidence in support of the use of light therapy across a spectrum of oral hard and soft tissues, as well as in a variety of important dental subspecialties, such as endodontics, periodontics, orthodontics, and maxillofacial surgery. The merging of diagnostic and therapeutic light procedures is also seen as a promising area for future expansion. In the next decade, several light technologies are foreseen as becoming integral parts of modern dentistry practice.

SignificanceThe function of our biological clock is dependent on environmental light. Rodent studies have shown that there are multiple colors that affect the clock, but indirect measures in humans suggest blue light is key. We performed functional MRI studies in human subjects with unprecedented spatial resolution to investigate color sensitivity of our clock. Here, we show that narrowband blue, green, and orange light were all effective in changing neuronal activity of the clock. While the clock of nocturnal rodents is excited by light, the human clock responds with a decrease in neuronal activity as indicated by a negative BOLD response. The sensitivity of the clock to multiple colors should be integrated in light therapy aimed to strengthen our 24-h rhythms.

Review
Photochemical reactions are numerous in the skin. They generate reactive oxygen species and other biochemical alterations as well. According to their nature, the molecular components of the skin which have been altered by these mechanisms can be repaired with various degrees of efficacy.
