N2 - This study aimed to evaluate the influence of the curing time of a light emitting diode (LED) curing unit on the diametral tensile strength of packable composite resin with 1 second-3 seconds from an ultra high intensity LED (Flash Max, intensity 4000 mW/cm2) and 20 seconds from a conventional LED (Ledmax 450, intensity 450 mW/cm2). We used an universal testing machine and the results showed a diametral tensile strength of 31.19 ± 6.84 MPa; 42.91 ± 8.26 MPa; and 52.53 ± 7.52 MPa. The result of an independent t-test was statistically significant (p < 0.05). We concluded the curing time of an ultra high intensity LED curing unit influences the diametral tensile strength of packable composite resin.
