Table 3

Frequency of distribution of adhesive remnant index scores (%).

Group	Appliance	Contamination	ARI = 0	ARI = 1	ARI = 2	ARI = 3
1	Orthodontic bracket	Dry environment	0 (0.0%)	1 (5.0%)	15 (75.0%)	4 (20.0%)
2	Orthodontic bracket	Water contamination	15 (75.0%)	4 (20.0%)	1 (5.0%)	0 (0.0%)
3	Orthodontic bracket	Saliva contamination	14 (70.0%)	4 (20.0%)	1 (5.0%)	1 (5.0%)
4	Disinclusion button	Dry environment	0 (0.0%)	3 (15.0%)	12 (60.0%)	5 (25.0%)
5	Disinclusion button	Water contamination	4 (20.0%)	14 (70.0%)	2 (10.0%)	0 (0.0%)
6	Disinclusion button	Saliva contamination	2 (10.0%)	16 (80.0%)	1 (5.0%)	1 (5.0%)
