Posterior teeth come on a card of eight teeth.

Posterior teeth come on a card of eight teeth.

• A. Six
• B. Four
• C. Twelve
• D. Eight

Answer: (D)

Posterior teeth are the premolars and molars located behind the canines. On a standard teaching or practice card used in dental labs, the posterior section is represented by eight teeth. This usually means two of each relevant posterior tooth type: two first premolars, two second premolars, two first molars, and two second molars. Third molars are typically not included on this card, which is why the total comes to eight. The other counts don’t fit because six would miss a pair of teeth, four would omit too much of the posterior row, and twelve would include third molars or extra copies not part of this standard card.
