  author={Panna Mangat and Anil Kumar Dhingra and Gaurav Bhardwaj},
  journal={IOSR Journal of Dental and Medical Sciences},
Curing of composites is a complex mechanism. Light is used to activate the photo-initiator system in the light curing units. Ideal requirements for curing light have been mentioned in the article. The article also sums up the various generations focusing on advantages, disadvantages and various advances in the same field. It has been concluded that an appropriately polymerized material has a positive influence on both the physical and biological properties of the restoration and should aid in… Expand
Light-curing unit (devices)
Bonding is the most published and researched procedure in orthodontics. Since its inception in 1954 by Buonocore, bonding material and technique have undergone major innovations and upgrading.Expand
Structural and mechanical analysis of three orthodontic adhesive composites cured with different light units
The different DC and the surface hardness properties were recorded for the resin as orthodontic adhesives depending on different light units. Expand
Assessing Dental Light-curing Units’ Output Using Radiometers: A Narrative Review
Dental practitioners as well as dental students are advised to control regularly every LCU by using the same handheld radiometer, as Irradiance values reported by radiometers do not match accurately with those delivered by laboratory power meters. Expand


Light-curing considerations for resin-based composite materials: a review. Part I.
This review, which is divided into two parts, discusses the contemporary light-curing units and the clinical considerations regarding light curing of RBCs that are important for achieving optimal curing and maximum polymerization of R BCs in a clinical setting. Expand

Evaluation of light curing units used for polymerization of orthodontic bonding agents.
Although the Turbo tip enhanced light intensity at zero-mm distance, reduction of light intensity by Turbo tip was demonstrated at five- to 20- mm distance, resulting in no significant difference. Expand
Degree of conversion and temperature rise during polymerization of composite resin samples with blue diodes.
This study compared the degree of conversion (DC) and temperature rise of four hybrid composite materials and revealed only a little bit higher DC values in case of polymerization with even 66 times stronger halogen curing units which showed twice higher temperature than blue diodes. Expand

Restorative Dentistry: Dental composite depth of cure with halogen and blue light emitting diode technology
An LED LCU with an irradiance 64% of a halogen LCU achieved a significantly greater depth of cure and the LCU's spectral distribution of emitted light should be considered in addition to irradiance as a performance indicator. Expand
