In the modern dentistry, dental curing lights have gained a pole position in all dental operations and practices, as all dental adhesives, adhesive cements, and resin composites use light energy for comprehensive polymerization, which decides the eventual clinical success of a dental operation. However, light curing is often taken for granted, as diagnosis analysis, preparation and the development of enhanced resins and adhesives and resins take all the attention away. Dental professionals need to opt for ideal dental curing lights as improper polymerization of materials can result into clinical failures, including marginal discoloration, de-bonding issues, and sensitivity.
