Endodontics has gone through many changes in the past several years. Electronic apex locators and surgical microscopes have taken a lot of the guess work out of doing root canal.

Attention is drawn to the pioneering contribution of Dr Henry A. de Lautour to the practice of radiology in New Zealand and a brief sketch of his life and work is recorded.

A 75-year follow-up radiograph shows that all but one of the lead pellets still remain in his hand.
