The eruption of maxillary premolars typically occurs between the ages of 10 and 11 years. This is a normal developmental milestone in the growth of permanent teeth. During this time, the primary (baby) teeth are being replaced by the permanent teeth, and the maxillary premolars are among the teeth that erupt during this stage. It is important to note that individual variations can occur, and some children may experience the eruption of their maxillary premolars slightly earlier or later than the average age range provided.Rate this question:

Maxillary premolar - Occlusal - Which of the following are true statements with respect to the Occlusal:
- A.
B cusp: largest, longest, sharpest; tip to DB; Cusp ridges (-4)
- B.
Inclined planes - MB and DB non-functional; ML and DL - functional
- C.
L cusp to ML; MB, DB, and DL inc planes functional; ML non-functional
- D.
B cusp: smallest, shortest, ovoid, tip to DB; Cusp ridges 4
- E.
Inclined planes - MB and DB functional; ML and DL - non-functional
Correct Answer
C. L cusp to ML; MB, DB, and DL inc planes functional; ML non-functionalExplanation
In maxillary premolars, the lingual (L) cusp is typically oriented towards the mesiolingual (ML) direction. The inclined planes of the mesiobuccal (MB), distobuccal (DB), and distolingual (DL) cusps are generally functional, while the mesiolingual (ML) inclined plane is non-functional.
Options 1 and 4 contain inaccuracies in describing the buccal (B) cusp. In maxillary premolars, the buccal cusp is usually larger and longer than the lingual cusp. Additionally, the cusp tip is commonly directed toward the buccal (DB) aspect, not the distolingual (DL) aspect.
Option 2 contains inaccuracies regarding the functional and non-functional inclined planes. In maxillary premolars, the mesiobuccal (MB) and distobuccal (DB) inclined planes are typically functional, while the mesiolingual (ML) and distolingual (DL) inclined planes are non-functional.Rate this question:

Maxillary Premolar Roots - Type I - Select the true statements below about Type I roots in maxillary premolars:
- A.
Single root
- B.
Kidney shaped at mid root cross section due to mesial concavity continuous with the root concavity (longitudinal groove)
- C.
Double root
- D.
Triangular shaped at mid root cross section due to mesial concavity continuous with the root concavity (longitudinal groove)
Correct Answer(s)
A. Single root
B. Kidney shaped at mid root cross section due to mesial concavity continuous with the root concavity (longitudinal groove)Explanation
In maxillary premolars with Type I roots, the accurate statements are that they typically possess a single root and exhibit a kidney-shaped appearance at the mid-root cross-section due to the presence of a mesial concavity and a continuous root concavity (longitudinal groove), which is more pronounced on the mesial aspect. These characteristics distinguish them from teeth with double roots or triangular shapes at the mid-root cross-section, which are more commonly associated with multi-rooted teeth like molars. Therefore, for Type I roots in maxillary premolars, a single, kidney-shaped root with specific concavities and grooves is the norm.Rate this question:
