Abstract

The invention relates to a tooth shade measurement device (1) comprising a casing (11), a handle (10) and a measurement head (20), said device being characterised in that the measurement head (20) comprises: a hollow body (40) extending along a longitudinal axis (46), said hollow body comprising a proximal end (48) and a distal end (49) that is bent away from the longitudinal axis (46), said distal end (49) being equipped with a removable end-piece (26) intended to come into contact with a tooth analysis surface; and at least one light source and image capture means solidly connected to the hollow body (40), whereby the light from the light source can be transmitted from the proximal end to the distal end of the hollow body. The device also comprises an orientation assembly that can be used to mount the proximal end (48) of the hollow body in the casing (11) such that the measurement head (20) occupies different angular positions in relation to the casing (11).
