Influence of Different Cordless Light-emitting-diode Units and Battery Levels on Chemical, Mechanical, and Physical Properties of Composite Resin.

摘要: Clinical relevance Irradiance may decrease as the light-emitting diode (LED) is discharged. Therefore, LED must be charged carefully to prevent possibility of influencing chemical, mechanical, and physical properties composite resin. Summary The aim this study was evaluate influence different curing units battery levels on resins. irradiance for each cycle from full completely discharged level evaluated, five new cordless units: Optilight Color (Gnatus), Bluephase (Ivoclar), Valo (Ultradent), Radii Plus (SDI), Xpert (SDI). After evaluation, resin specimens were prepared light cured, while varying unit: high (HL, 100%), medium (ML, 50%), low (LL, 10%). degree conversion, diametral tensile strength, sorption, solubility also evaluated. Data checked homoscedasticity submitted two-way three-way analysis variance, depending test performed, followed by Tukey with a significance 95%. A negative correlation found between cycles curing, which Pearson test. not influenced in any performed. However, some can
