1. Define dental anatomy and morphology

Answer explanation

-Dental anatomy -is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. - Morphology - is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features.

1. What are the two dentition?

Answer explanation

Primary and permanent

what are the older terms for the two dentition

Answer explanation

deciduous and secondary

what is the difference between succedaneous and nonsuccedaneous

Answer explanation

- Succedaneous teeth are permanent teeth that will be replacing primary teeth, while nonsuccedaneous teeth will just grow in, not replacing any primary teeth above it.

1. State the tooth types in the initial dentition and each of their numbers and functions.

Answer explanation

- Incisors D,E,F,G,N,O,P,Q and are used for cutting, and biting. -Canines C,H,M,R and are used for piercing, and tearing. -Molars A,B,I,J,K,L,S,T and are used for grinding.

1. State the tooth types in the next dentition and each of their numbers and functions.

Answer explanation

- Incisors 7,8,9,10,23,24,25,26 and are used for cutting, and biting. -Canines 6,11,22,27 and are used for piercing, and tearing. -Premolars 4,5,12,13,20,21,28,29 and are used for piercing, tearing, and grinding. -Molars 1,2,3,14,15,16,17,18,19,30,31,32 and are used for grinding.

Universal Tooth Designation System

Answer explanation

the primary teeth are designed in a consecutive arrangement by using capital letters, A through T, starting with maxillary right second molar, moving clockwise, and ending with the mandibular right second molar what permanent is numbered 1 -32

International Standards Organization Designation System

Answer explanation

uses a two-digit code for each tooth. The first number (1-4) indicates what quadrant the tooth is in. the second number (1-8) indicates where that tooth sits in the quadrant already specified, one being the central incisor-8 being the third molar.

Palmer Notation Method

Answer explanation

also known as the Military Tooth Numbering System is most used in orthotics. Like the International Standards Organization Designation System, permanent teeth are designated a number 1-8 (1 being the central incisor and 8 being the third molar). What differentiates this system from the ISODS is instead of a first number being in place to tell what quadrant the tooth is found in, there is an angle symbol that indicates the quadrant.

1. What are the three dentition periods, and how are they different from one another?

Answer explanation

- The three dentations periods are primary dentition period, mixed dentition period and permanent dentation period. - Primary Dentition Period: this is the "baby tooth" or "deciduous dentition stage" this period is from 6 months - 6 years. This stage is completed at approximately 30 months and is the beginning of jaw growth. This stage ends when the first permanent tooth erupts. -Mixed Dentition Period: This stage occurs roughly between 6 to 12 years of age. During this time primary teeth are shed and permanent teeth begin to erupt after the crowns are complete. This period begins with the eruption of the first permanent tooth and ends when the last primary tooth is shed. -Permanent Dentition Period: this period starts as soon as the last primary tooth is shed and starts at approximately after 12 years of age. The total number of teeth in this phase is 32 if normal (8 incisors, 4 canines, 8 premolars, 12 molars). The permanent dentation period is the only dental period with molars.
