Fig. 1From: The antibacterial efficacy of photon-initiated photoacoustic streaming in root canals with different diameters or tapersThe ATP value in the root canal systems after irrigation. A The reduction of ATP after conventional needle irrigation (CNI) or photon-induced photoacoustic streaming (PIPS) is shown. The values are presented as mean and standard deviation. B The ATP values before and after irrigation are shown as mean and standard deviation. Statistical significance is represented by uppercase lettersBack to article page
