Phenotypic Features and Salivary Parameters in Patients with Ectodermal Dysplasia: Report of Three Cases

Table 1

Amount of salivary flow and buffering capacity of saliva, and counts of mutans streptococci, lactobacilli, and yeast in patients with ED.

Salivary tests	Patient 1 (HidED)	Patient 2 (HED)	Patient 3 (HED)
Salivary flow rate (mL/min)
Normal flow: >1.0	1.0 (limit value)	1.2 (normal)	<0.1 (xerostomia)
Limit value: 1.0
Reduced flow: ≤0.7
Xerostomia: ≤0.1
Buffering capacity of saliva (pH value)
Normal: 5.1–7.0	4.0 (limit value)	6.0 (normal)	5.0 (limit value)
Limit value: 4.0–5.0
Low buffering capacity: <4.0
Mutans streptococci (log·cfu/mL)
High caries risk: >5.0	6.2 (high)	5.0 (high)	4.9 (high)
Lactobacilli (log·cfu/mL)
Low caries risk: 0.0–3.0	0.0 (low)	2.75 (low)	1.70 (low)
Moderate caries risk: 3.0–3.7
High caries risk: >4.0
Yeasts (log·cfu/mL)
No caries risk: 0–1.0	3.0 (high)	0.0 (no caries risk)	2.78 (high)
Moderate caries risk: 2.0–2.6
High caries risk: >2.6

HidED, hidrotic ectodermal dysplasia; HED, hypohidrotic ectodermal dysplasia.
