______ ______ doesn't have mamelons and crowns are wider than tall

Correct Answer
Primary max central incisor

Explanation
The primary max central incisor is a type of tooth in the primary dentition. It does not have mamelons, which are the rounded bumps on the incisal edge of newly erupted teeth. Additionally, the crowns of primary max central incisors are wider than they are tall.

_________ ______ has a prominent cingulum and has 1 root long and slender

Correct Answer
Primary man central incisor

Explanation
The given correct answer is "Primary man central incisor." The primary mandibular central incisor is a tooth in the primary dentition that is located in the lower front of the mouth. It is characterized by having a prominent cingulum, which is a raised area on the lingual surface of the tooth. Additionally, it has a single root that is long and slender in shape.

_______ _________ has a crown that is smaller than permanent, tall & thin opposite than central

Correct Answer
Primary max lateral incisor

Explanation
The primary maxillary lateral incisor is a tooth in the primary dentition that is located in the upper jaw. Compared to the permanent lateral incisor, the primary maxillary lateral incisor has a smaller crown size. Additionally, it is described as being tall and thin, as opposed to the central incisor which is wider and more central in position.

What tooth has a sharp root apex

Correct Answer
primary max lateral incisor

Explanation
The primary maxillary lateral incisor is a tooth located in the upper jaw. It is known for having a sharp root apex, which refers to the pointed tip of the tooth's root. This sharp apex allows for efficient and effective anchoring of the tooth in the jawbone.

What tooth has a cingulum and marginal ridge that is very prominent

Correct Answer
primary max central incisor

Explanation
The primary maxillary central incisor is the tooth that has a cingulum and marginal ridge that is very prominent. The cingulum is a raised, rounded area on the lingual surface of the tooth, and the marginal ridge is the elevated area that forms the mesial and distal borders of the lingual surface. In primary maxillary central incisors, these features are typically more pronounced compared to other teeth, making them easily identifiable.

7.

What tooth has a deep fossa

Correct Answer
primary max central incisor

Explanation
The primary max central incisor tooth has a deep fossa. Fossae are depressions or grooves on the surface of teeth, and the primary max central incisor tooth specifically has a deep one. This characteristic is unique to this tooth and helps in its identification and differentiation from other teeth.

8.

What primary tooth is larger than the central with a root that turns distal

Correct Answer
primary man lateral incisor

Explanation
The primary mandibular lateral incisor is larger than the central incisor in the primary dentition. Additionally, the root of the primary mandibular lateral incisor turns distally, meaning it curves towards the back of the mouth.

9.

What primary tooth has a crown that is wider & longer than the mandibular central incisor

Correct Answer
primary man lateral incisor

Explanation
The primary mandibular lateral incisor is the primary tooth that has a crown wider and longer than the mandibular central incisor. This means that the lateral incisor in the lower jaw is larger in size compared to the central incisor in the same jaw.

10.

Crown has a long & sharp cusp, and a well developed cingulum

Correct Answer
primary max canine

Explanation
The given answer "primary max canine" is correct because primary maxillary canines have a long and sharp cusp, which helps in tearing food. They also have a well-developed cingulum, which is a rounded elevation on the lingual surface of the tooth. These characteristics are consistent with the description provided for the crown.

11.

Lingual surface is smaller than max with a shallow lingual fossa

Correct Answer
primary man canine

Explanation
The given answer is referring to a primary mandibular canine tooth. It suggests that the lingual surface of this tooth is smaller compared to the maxillary canine tooth and has a shallow lingual fossa. This means that the inner surface of the tooth facing the tongue is relatively smaller and the depression on this surface is not very deep.

12.

Has a tubular root that curves distal

Correct Answer
primary max canine

Explanation
The given correct answer, "primary max canine," suggests that the tooth being described has a tubular root that curves distally. This indicates that the tooth in question is located in the primary maxillary (upper jaw) dentition and is specifically referring to the canine tooth. The term "primary" suggests that it is a deciduous or baby tooth rather than a permanent tooth. Canine teeth are typically the longest and most pointed teeth in the mouth, used for tearing and cutting food.

Root is shorter than max

Correct Answer
primary man canine
14.

Has 3 roots, the lingual root is the longest MB DB L

Correct Answer
primary max 1st molar

Explanation
The primary maxillary first molar typically has three roots, with the lingual root being the longest. The abbreviation "MB DB L" likely refers to the three roots: mesiobuccal (MB), distobuccal (DB), and lingual (L). Therefore, the correct answer is the primary maxillary first molar.

Has 4 cusp, 2 roots, mesial root is larger than distal root

Correct Answer
primary man 1st molar

Explanation
The given answer, "primary man 1st molar," is correct because primary mandibular first molars typically have 4 cusps, 2 roots, and the mesial root is larger than the distal root. This description matches the characteristics of a primary mandibular first molar, making it the correct answer.
