Macrophotograph of an extracted molar (male,upper,number 7),sectioned with a glass cutting wheel. A root was broken during extraction. The molar shows two amalgam fillings,a powdered alloy consisting of silver,tin,copper & zinc mixed with mercury. The decayed area is removed & the cavity lined with a white filler (seen),which protects the base of the cavity from the effects of the filling itself. The open channel running up the root & across the tooth is the dental pulp containing blood vessels,nerves & lymphatics. A layer of enamel covers the crown,beneath which is the dentine (both seen here) running down the roots. Magnification:X 1.4 (at 35mm size) | |
