OBJECTIVE:   The  aim  of  this  in  vitro  study  was  to  assess  the  effect  of  different   poliwave  MulLLED  curing  lights  on  surface  microhardness   topography  of  two  nanofilled  composites.  The  hypothesis  is  that   polywave  mulLLED  curing  lights  induce  uniform  microhardness   distribuLon  on  composite  surface.  

RESULTS:  

CONCLUSIONS:  

Two-­‐way  Anova  showed  comparable  results  for  both  composites   (Filtek  and  GrandioSo).  The  two  variables  (lamp  and  zone)  staLsLcally   affected  micro-­‐hardness  (p
