Abstract
We report the case of a new type of dental shaping practiced post-mortem on two lower canines belonging to an individual who had been deposited in the main corridor of the double megalithic monument called A4 passage-grave of the Neolithic Necropolis at Chenon (Charente, France). The main purpose of the present study based on ESEM microscopic observation of human teeth was to examine the trimming process used to shape these teeth. The ESEM observations were performed at different magnifications (30X, 100X, 200X, 500X) on the fractured lingual face, near the CEJ, near the pulp cavity and on the edge of the crown. The tooth shaping was done symmetrically on the two canines, from top to bottom of the lingual side, halfway up the crown, from the mesial face to the distal face, descending a little lower than the CEJ under the gum. A polishing of the exposed surface completed the proceeding. This type of teeth shaping has not been listed until now within the classifications of canine shaping. Known trimmed canines are either pyramid-shaped or L-shaped and observed from Neolithic period to Iron age in Spain.
