3.) When does the Transitional or Mixed Dentition Period begin and end?
The Transitional Dentition Period lasts from 6 to 12 years of age The Transitional or Mixed Dentition Period is defined by the presence of both Primary and Permanent teeth in the oral cavity
The Deciduous Dentition Period ends when the initial permanent tooth erupts into the oral cavity When the initial Permanent Mandibular First Molar erupts at approx. 6 years of age
5.) In the dental formula, the letters I, C, P, & M represent which teeth?
I 2/2, C 1/1, M 2/2 x 2 = 20 The dental formula for the Primary / Deciduous Dentition
I 2/2, C 1/1, P 2/2, M 3/3 x 2 = 32 The dental formula for the permanent dentition
8.) Please annotate the Dentition to the right using all 3 systems presented in class.
9.) Please annotate the Dentition to the right using the International and Universal systems.
Enamel is the tooth tissue that covers the crown of the tooth
Cementum is the tooth tissue that covers the root of the tooth
12.) What two terms can be used to describe the junction of these two tooth tissues?
Cemento-enamel Junction Cervical Line The Cemento-enamel Junction can be abbreviated CEJ
DentinPulp The four tissues of the tooth: Enamel Cementum Dentin Pulp
14.) Name the portion of the Maxilla or Mandible which supports the teeth within the jaw and surrounds the root of the tooth.
The Alveolar Process The Alveolus is the CAVITY or SOCKET in the alveolar process of the Mx and Mn in which the root or roots of the teeth are fixed
15.) Name the surface of the central incisor facing the lip.
Labial (La) surfaces which face the lip on anterior teeth are called Labial surfaces, and can also be referred to generically as Facial surfaces
Buccal (B) surfaces which face the cheek on posterior teeth are called Buccal surfaces, and can also be referred to generically as Facial surfaces
17.) Name the surface of any tooth which faces toward adjoining teeth in the same dental arch.
Proximal surfaces of the teeth which face adjoining teeth in the same dental arch are generically called Proximal surfaces
18.) Name the surface of the tooth facing toward the midline while following the curve of the dental arch.
Mesial (M) the surfaces of teeth which face the midline while following the curve of the dental arch are called Mesial surfaces
19.) Name the surface of the tooth facing away from the midline while following the curve of the dental arch.
Distal (D) the surfaces of teeth which face away from the midline while following the curve of the dental arch are called Distal surfaces
20.) Name the surface of any tooth that faces toward the tongue.
Lingual (Li) all teeth have a Lingual surface, it is the surface facing toward the tongue
