In health, the length of the junctional epithelium ranges from:

0.5-2mm
2-2.5mm
0.1-0.75mm
0.25-1.35mm

The correct answer is: 0.25-1.35mm

In health, the length of the junctional epithelium typically ranges from 0.25mm to 1.35mm. This is the area where the oral epithelium attaches to the tooth surface at the base of the gingival sulcus or periodontal pocket. The junctional epithelium plays a crucial role in protecting and maintaining the health of the underlying periodontal structures. Option A (0.5-2mm) is too broad and includes a range that is higher than usual for the length of the junctional epithelium. Option B (2-2.5mm) is outside the typical range and is too long for the junctional epithelium. Option C (0.1-0.75mm) has a lower range that is below the typical length of the junctional epithelium. The correct answer, option D (0.25-1.35mm), falls within the generally accepted range for the length of the junctional epithelium in health.
