Figure 4: Schematic representation of dentin biopsy site. The biopsy specimen (black bar) is taken at right angles to the longitudinal axis of the tooth midway between the occlusion plane and the cementoenamel junction; the microtrephine penetrates exactly 2 mm into the dentin. Biopsy locations for investigation of the influence of biopsy layer
