Clinical and Antimicrobial Evaluation of Copaifera langsdorffii Desf. Dental Varnish in Children: A Clinical Study

Table 1

Amount of S. mutans, expressed as the logarithm of the number of colony forming units (CFU) per mL of saliva, measured in saliva samples with dilution of 1 : 10 on days 0 (pretreatment), 90, 180, and 360 in patients treated with chlorhexidine, fluoride, and copaiba varnishes.

	Chlorhexidine	Fluoride	Copaiba	Significance (ANOVA)
	Mean ± SD	Mean ± SD	Mean ± SD
0	0.58 ± 0.43	0.86 ± 0.37	1.32 ± 0.61^a,d
90	0.38 ± 0.23	0.51 ± 0.33^x	0.99 ± 0.57^a,c,y
180	0.33 ± 0.14^y	0.41 ± 0.24^x	0.39 ± 0.22^x,z
360	0.55 ± 0.52	0.53 ± 0.44^x	0.12 ± 0.19^b,d,x,z
Significance (repeated measures ANOVA)				—

SD, standard deviation; ANOVA, analysis of variance. The letters ^a and ^b denote statistically significant differences in relation to the chlorhexidine varnish on the same day, while the letters ^c and ^d indicate statistically significant differences in relation to the fluoride varnish on the same day (Tukey test). The letters ^x and ^y designate statistically significant differences in relation to day 0 in the same group, while the letter ^z denotes statistically significant difference in relation to day 90 in the same group (Tukey’s test).
