Study Notes
Chapter 11 - Review of Dentitions
- Two sets of teeth in a lifetime: Primary and Permanent dentitions.
- Primary dentition comprises 20 teeth; Permanent dentition consists of 32 teeth.
- Dental arches are divided into four sections known as quadrants.
- Teeth categorized as front (anterior) and back (posterior).
- Four types of teeth: incisors, canines, premolars, and molars.
- Canines are the "cornerstone" of the dental arch, providing stability.
- The five surfaces of teeth are facial, lingual, masticatory (occlusal), mesial, and distal.
- Interproximal space refers to the space between adjacent teeth.
- Contact area is the site where adjacent teeth physically touch.
- Embrasure is the triangular space between adjacent teeth, directed toward the gingiva.
- Line angle denotes the junction of two tooth surfaces.
- Apical third indicates the area nearest the end of the root.
- Functional occlusion describes teeth positions during chewing movements.
- Malocclusion defines teeth that are in poor occlusion.
- Class III malocclusion is termed mesioclusion.
- Neutral occlusion is classified as Class I.
- Curve of Wilson describes the curvature of the occlusal plane.
Chapter 12 - Tooth Morphology
- Permanent dentition includes 12 anterior teeth.
- Succedaneous teeth replace primary teeth.
- Cingulum refers to the rounded, raised area on the cervical third of the lingual surface of anterior teeth.
- Newly erupted central and lateral incisors exhibit mamelons on the incisal ridge.
- Permanent canines are the longest teeth in the permanent dentition.
- Mandibular central incisors are the smallest teeth in the permanent dentition.
- Imbrication lines are developmental horizontal lines on anterior teeth.
- Marginal ridges border the occlusal table of posterior teeth.
- Developmental pits are the pinpoint depressions where two or more grooves meet.
- Mandibular second premolars have two morphological forms: Tricanineate (three cusp type) and Bicanineate (two cusp type).
- A trifurcated tooth has three roots.
- Nonsuccedaneous teeth do not replace primary teeth.
- The fifth cusp on a maxillary first molar is called the cusp of Carabelli.
- Wisdom teeth refer to the third molars.
- Mandibular molars possess two roots.
- Enamel covering on primary teeth is relatively thin.
- Universal/National Tooth-Numbering System designates primary dentition with letters A-T.
- Primary anterior incisors do not have mamelons.
- Maxillary first molars exhibit an H-shaped groove pattern on the occlusal surface.
- The largest primary mandibular molar is the second molar.
