Question

Quizplus · Accepted Answer

The spillway, also known as the embrasure, is the V-shaped space between adjacent teeth that allows for self-cleaning mechanisms and prevents food from impacting between the teeth.

Answer: B
 The crest of curvature is the highest point on the buccal and lingual surfaces of a tooth that contribute to proper alignment and occlusion.

Answer: C
 The cervical line, also known as the cementoenamel junction, is the point where the tooth's crown meets the root and serves as a boundary between the enamel and cementum, which are both important components for protecting the tooth.

Answer: A
 The interdental space, also known as the interproximal space, is the area between adjacent teeth where the gum tissue is located. Proper tooth alignment is important for maintaining healthy gum tissue and preventing periodontal disease.

Answer: E
 Occlusal contact refers to the way in which the upper and lower teeth meet and function during biting and chewing. Proper alignment and occlusion help to protect the periodontium and preserve the dentition.
