Ventajas y desventajas del uso de lámparas LED en odontología. Revisión sistemática.

Abstract

Problem: The lack of knowledge of the ideal values for the LED lamps is one of the main problems. Since increased values can cause eye damage, death of the dental pulp among others. It is important to know the values of the wavelength and intensity of the light. Objective: Analyze different indications and contraindications for correct management of a LED lamp in dentistry. Materials and Methods: A systematic review, retrospective, descriptive, non- experimental, qualitative, analytical, deductive method. The use of P.I.C.O.S analysis for obtaining keywords: LED lamp, wavelength, maintenance, polymerization time, cure distance; using biomedical database such as PubMed, Google Scholar and Web of Science. A universe of 50 articles was obtained, by inclusion and exclusion criteria, 30 scientific articles were selected to work on. Results: It was observed 300 – 400 nm as an ideal range. This wavelength could be very effective in activating a photoinitiator. In which it is recommend about 10 to 25 seconds. A correct management of the LED lamp battery will lead to its have their correct function. Discussion: Studies of Lopez O et al. describe that due to the misuse of the lamps, 39% of the units have an inadequate intensity and are different from those of Madhusudhana. K et al., who report 44% of devices with inadequate intensity Conclusion: LED lamps, compared to other lamps, stand out in having better properties. Among those that stand out we have: it’s ergonomics, low weight and wireless, and also it stands out in its effectiveness and durability.
