MIH-effected carious permanent first molar teeth were well-demarcated white/yellow or brown/yellow enamel opacities which is a sign for hypomineralization and asymptomatic which meant to be without any spontaneous pain or pain during eating or drinking, percussion or palpation tenderness, formation of abcess or fistula.

The carious not MIH-effected teeth were only carious without any hypomineralize areas and asymptomatic which meant to be without any spontaneous pain or pain during eating or drinking, percussion or palpation tenderness, formation of abcess or fistula.

MIH-effected teeth were carious permanent first molar teeth with well-demarcated white/yellow or brown/yellow enamel opacities which is a sign for hypomineralization and did not have any sign of caries.

Cold test evaluation to describe the sensitivity level of teeth due to induce the hydrodynamic forces in dentine tubules.

Visual Analog Scale for Pain was used to evaluate the cold tests for before and after the local anesthesia. Visual analog scale was used to rate the sensitivity level of patients with 6 different faces representing different levels of pain from "0=no pain" to "10=unbearable pain".

Electrical pulp test values at which patients felt sensitive were recorded.

Visual Analog Scale for Pain was used to evaluate the pain during the treatment. Visual analog scale was used to rate the sensitivity level of patients with 6 different faces representing different levels of pain from "0=no pain" to "10=unbearable pain".
