Final answer:
Enamel hypocalcification is characterized by weakened and discolored enamel, leading to increased vulnerability to cavities and decay. Clinical signs of this condition include fatigue, slowed growth, digestive problems, light sensitivity, and epithelial problems like cracks in the corners of the mouth.
Step-by-step explanation:
The clinical signs of enamel hypocalcification include fatigue, slowed growth, digestive problems, light sensitivity, and epithelial problems like cracks in the corners of the mouth. Enamel hypocalcification refers to a condition where there is a deficiency of calcium in the enamel of teeth, leading to weakened and discolored enamel. This can make the teeth more susceptible to cavities and decay.
