Serrations are moderately coarse near the base, gradually becomine finer towards the tip. The base of the root is prominently arched.
Lower teeth are very erect, finely serrated, and have long cusps.
Enamel extends well down over the root shoulders. Root bases are gently arched. 1 - labial and Fig. Lower tooth on bottom.
