introduction, history of lasers and laser light production
\"Laser\" is the first letter of \"radiation stimulation emission light amplification. Its theoretical basis was put forward by Einstein. The first tooth that was exposed to the laser was in 1960. Laser can be applied to almost any clinical condition. Laser in dentistry is a unique non- Depending on the specific parameters of the wavelength, power, and target tissue, it can be used as an ionization form of a controlled source of tissue stimulation, cutting, or ablation. The theoretical basis of laser light generation was developed more than 90 years ago; 47 years ago, the first laser was used for tooth extraction. Perhaps a bit surprising is that commercial lasers have been used only for dental practice for the last 18 years. In connection with the launch of the first \"dental\" laser, there was a certain degree of hype that quickly led to the frustration of dentists and research, which made many claims of clinical use unreliable or minimized (). Unlike many medical and surgical fields, laser therapy is the only source of treatment, in dentistry, the use of lasers is considered to be an aid in the organization management phase that contributes to the achievement of complete hard tissue or soft tissue surgery. For dental professionals in general clinics, patients are willing to accept a procedure that is usually associated with pain stimulation errors, which may compromise the provision of dental treatment. Most patients flinch when they think high or low. Rapid electric drills and people exposed to surgery found that related bleeding and tissue bruises could interfere with normal language and dietary functions. Explore possible laser envelopes with as much hope as possible Tissue interaction, most of the hype about laser use in dentistry focuses on the possibility of encouraging patients to absorb by avoiding the surrounding environmentand post- Pain and discomfort in surgery. Of course, today\'s laser offers an opportunity to provide hard and soft lasers. At least in the outline, make it easier for patients to experience tissue therapy ( ,). As seen in later articles in this series, a great deal of research has been done on the surface to verify the innovative use of lasers in all branches of dentistry. In the worst case, the claims of beneficial use in some areas have been blacked out; Often, other uses have been shown to overcome the shortcomings of traditional therapies. Lasers can be applied to almost any clinical situation, but in many cases, their efficacy is unknown by traditional techniques, in addition to anecdotal reports. In essence, the auxiliary use of surgical laser in dentistry is designed to solve the efficient cutting of hard tissues in dentistry, stop-bleeding ablation of soft tissues, and the Essien effect generated through bacterial elimination. Not so powerful Surgical Lasers have been shown to alter cell activity, enhance biochemical pathways associated with tissue healing, contribute to the detection of dental caries, and contribute to the curing of composite repair materials. The decision to incorporate lasers into daily dental care will depend not only on financial considerations of how to use lasers to improve practical profitability; The biggest factor in making this decision will be to understand how the laser wavelength interacts with oral tissue and how this use improves patient management.
