Table 3.

Mean and standard deviation for total Acoustic Events (AE) and for AE greater than 60 dB from start of light curing until 20 minutes after. Values followed by the same superscript on the same column are statistically similar (α=5%).

	AE total	AE>60 dB
Z250XT 20s	42.4 (19.3) AB	4.6 (4.2) AB
Z250XT 40s	56.5 (16.4) A	5.4 (2.1) A
Z250XT 68° 20s	49.9 (27.1) AB	4.1 (3.9) AB
Z250XT 68° 40s	63.5 (32.9) A	5.9 (3.6) A
Filtek BulkFill 20s	214.1 (127.2) ^*	3.5 (3.2) AB
Z250XT TU 40s	26.3 (15.4) B	1.4 (1.4) B

The value for Filtek BulkFill at 20 s was excluded from the analysis of the total AE events since it was much higher than any of the other mean values.
