Question

On which of the following surfaces of permanent teeth is pit and fissure caries MOST likely to occur? A. Facial surfaces of maxillary first molars B. Lingual surfaces of maxillary first molars C. Facial surfaces of mandibular first premolars D. Lingual surfaces of mandibular first molars E. Proximal surfaces of mandibular incisors

Answer 1

B

Step-by-step explanation:

A pit is a tiny depression which is found on the surface of the tooth.

Fissures are the grooves that occur naturally on the biting surfaces of teeth.

Thus, pits and fissures are located on the lingual surfaces of the maximillary first molars because of the lingual fissures on the max molars.
