Real-Time Analysis of Temperature Changes in Composite Increments and Pulp Chamber during Photopolymerization

Table 1

Mean maximum temperatures (°C) at assigned measurement sites during polymerization of each increment.

	Measurement sites
	BC	MC	TC	BE	ME	TE	PD	CL
1st increment	52.8 (2.5)^b	59.8 (3.8)^a	N/A	48.4 (4.0)^b	51.3 (5.9)^b	N/A	39.8 (1.6)^c	50.7 (1.4)^b
2nd increment	46.7 (1.1)^df	51.7 (1.5)^bc	58.5 (2.1)^a	44.5 (1.4)^ef	48.0 (2.1)^cde	52.6 (4.0)^b	38.8 (0.1)^g	50.0 (1.3)^bd

Standard deviations are in parentheses.
Values with identical superscript letters are similar within the same increment (Tukey’s HSD, ).
N/A: Not applicable.
BC: bottom center of the cavity; MC: top center of 1st increment; TC: top center of 2nd increment; BE: bottom corner of 1st increment; ME: top corner of 1st increment; TE: top corner of 2nd increment; PD: bottom center on pulpal aspect of dentin; and CL: center of curing light guide tip.
