Study Notes

Tooth Designation and Dentition Systems

International Numbering System (INS) designates quadrants with the first digit; teeth are numbered 1 to 5 from the midline distally.
Primary teeth use digits 5 through 8 for the first digit; the second digit also uses 1 through 5 starting from the midline distally.
Palmer Notation Method uses right-angle symbols to indicate quadrants and arches, with tooth numbers placed inside the symbol.

Dental Anatomy Terminology

Root surfaces often have concavities (indentations).
The area between multiple roots is referred to as furcation.
Each tooth has five surfaces: facial (buccal/labial), lingual (palatal), occlusal, mesial, and distal.

Surface Orientation

Facial surfaces are closest to the face; anterior teeth have labial surfaces, and posterior teeth have buccal surfaces.
Lingual surfaces are closest to the tongue; those near the palate are termed palatal surfaces.
Masticatory surfaces are the chewing surfaces, with anterior teeth having incisal surfaces and posterior teeth having occlusal surfaces.

Proximal and Contact Areas

Mesial and distal surfaces define a tooth's proximity to the midline, while the area between adjacent teeth is called the interproximal space.
Contact areas are where adjacent teeth touch, and each tooth, except third molars, contacts two neighboring teeth (one mesial, one distal).

Line and Point Angles

Each tooth has line angles, with posterior teeth having 8 per tooth and anterior teeth having 6.
Point angles are defined at the junction of three tooth surfaces, and each tooth has four point angles.

Assignments and Examination

Workbook assignments include figures from the Student Workbook, emphasizing clarity and neatness in submissions.
Examination #1 covers chapters on face and neck regions, oral cavity and pharynx, and an overview of dentitions, including various types of questions.
Examination date is set for September 9th at 10:15 AM in MSA 006; preparation includes readings and reviews.

Administrative Notes

Use only blue or black ink; no pencils allowed.
Ensure clear writing to avoid point deductions for illegibility or spelling errors.
Submit assignments in person, staple them, and include full name and student ID.
