Radiograph of the African wild dog left maxillary (top) canine.

<p>All standardized measurements of the canine were performed by drawing a line on each radiograph at the cemento-enamel junction of the tooth. Pulp cavity width (dashed line) and tooth width (solid line) were then measured to calculate the pulp cavity/tooth width ratio.</p

<p>Tooth belonging to African wild dog DWD058, date of death was 11 July 2013 and known age 4 years. Photograph taken at Matson’s Laboratory, Manhattan, MT, USA, which assigned the correct age of 4 years, with confidence (certainly level A), based on counting 4 cementum annuli (indicated by arrows).</p
