Abstract
The use of light to initiate bonding reactions has become an integral part of orthodontic practice. Different technologies are available to cure dental composite, each with advantages and drawbacks. The efficacy of light-curing is affected by a range of factors and it is important for orthodontists to understand these concepts, alongside common problems with light-cure units, to aid in troubleshooting. Periodic testing of light-curing equipment can help to identify defective units that can potentially contribute to bond failure. CPD/Clinical Relevance: An understanding basic materials science in relation to dental light-curing technology is important in allowing orthodontists to maintain safe and effective equipment. The choice of light-curing equipment and method of use can influence bond strength and, therefore, treatment success.
