Question

Which tooth is considered the ""cornerstone"" of the permanent dentition? A) Maxillary canine B) Maxillary second molar C) Mandibular canine D) Mandibular first molar

Answer 1

The 'cornerstone' of the permanent dentition is the Maxillary Canine, which is important for tearing food and maintaining the dental arch and facial structure.

Step-by-step explanation:

The tooth considered the "cornerstone" of the permanent dentition is the Maxillary Canine (Option A). The canines are pointed teeth located on either side of the front teeth that are vital for tearing food. Given their position, they play a key role in maintaining the arch and the occlusion, which refers to the alignment and spacing of your upper and lower teeth when they are in contact. The maxillary canines are especially important in the dental arch for their guidance roles in occlusion and aesthetics. They provide important support for facial muscles as well, contributing to the overall facial structure.

Answer 2

The correct answer is option (A) Maxillary canine.

The tooth considered the "cornerstone" of the permanent dentition is A) Maxillary canine. Maxillary canines play a crucial role in the dental arch due to their strategic position and strong root structure.

They are situated at the transition point between the anterior and posterior teeth, aiding in guiding the jaws during closure and maintaining the arch's alignment.

Their long roots provide stability and support to the dental arch, and they are also important for esthetics and function, including biting and tearing food. The unique positioning and strength of maxillary canines make them pivotal in both dental occlusion and overall oral health.
