Tooth Morphology 2 Primary Dentition Teamwork Improving Kindness Safety Student name: This handbook is to be used in conjunction with your sessions on Primary Dentitions. 1 Task 1) Research the differences between the primary and permanent dentitions. Create a table/spider diagram Task 2) For each tooth (see templates below):  Complete the Chronology table  List 3-5 main identifying features  List the number of cusps (If any), roots and pulp horns  Record the dental notation using Palmer and FDI (both right & left) You may use the following resources to help to access the information required. Website: University of Leeds, The Tooth Morphology Lab dentapps.leeds.ac.uk/vlab/morphology/index.htm# (be aware to click on ‘Deciduous’ then onto each individual tooth on the model. (Note: All of the pictures are shown with the crown up, so for the maxillary teeth ensure to switch this round by clicking on ‘Crown down’. Book: Dental Morphology, An illustrated guide, Geoffrey C van Beek You may add pictures to your document and anything else which you feel will help your learning of this subject. I have completed the first tooth as an example. Maxillary (upper) teeth Maxillary central primary incisor 2  Chronology Initial calcification 3-4 months in utero Crown completion 4 months Eruption 7.5 months Root completion 1.5 years Notation (Palmer/FDI): URA, ULA/ 51, 61 Identifying features  Rounded disto-incisal angle, sharp mesio-incisal angle  Similar crown shape to permanent first incisor- primary one plumper & more rounded  Large palatal cingulum, pronounced bulge on labial surface  Root distal tilt, labially on axis –allows for permanent 1 to develop  Mesial & distal cervico-incisal dimension are similar Number of cusps: 0 Number of pulp horns: 2 (m & d) Number of roots: 1 Maxillary lateral primary incisor Chronology Initial calcification 4.5 months in utero Crown completion months Eruption Root completion Notation (Palmer/FDI): Identifying features  Similar shape to first primary incisor, although smaller and narrower in proportion, especially the crown Number of cusps: 0 Number of pulp horns: Number of roots: Maxillary primary canine Chronology Initial calcification 5 months in utero Crown completion 9 months 3 Eruption Root completion Notation (Palmer/FDI): Identifying features  Conical crown with pronounced ? bulge and pointed cusp Number of cusps: Number of pulp horns: 0 Number of roots: Maxillary first primary molar Chronology Initial calcification 5 months in utero Crown completion months Eruption 12-16 months Root completion Notation (Palmer/FDI): Identifying features  Conical crown with pronounced cervical bulge and pointed cusp Number of cusps: 4 Number of pulp horns: Number of roots: Maxillary second primary molar Chronology Initial calcification months in utero Crown completion 10-12 months Eruption Root completion Notation (Palmer/FDI): Identifying features  Cusp of ? present on mesio-palatal aspect  Very similar to ? first permanent molar morphology 4 Number of cusps: Number of pulp horns: Number of roots: Mandibular (lower) teeth Mandibular central primary incisor Chronology Initial calcification 4.5 months in utero Crown completion months Eruption 6.5 months Root completion Notation (Palmer/FDI): Identifying features  Smallest tooth in the dentition Number of cusps: 0 Number of pulp horns: Number of roots: Mandibular lateral primary incisor Chronology Initial calcification months in utero Crown completion 4.5 months Eruption 7 months Root completion Notation (Palmer/FDI): Identifying features  Smallest tooth in the dentition Number of cusps: Number of pulp horns: Number of roots: 5  Mandibular primary canine Chronology Initial calcification 5 months in utero Crown completion months Eruption Root completion Notation (Palmer/FDI): Identifying features  Smaller and slimmer than maxillary primary canine Number of cusps: Number of pulp horns: Number of roots: Mandibular first primary molar Chronology Initial calcification months in utero Crown completion 6 months Eruption Root completion Notation (Palmer/FDI): Identifying features  Tubercle of Zuckerkand present mesio-buccally on cervical area Number of cusps: Number of pulp horns: 3 Number of roots: Mandibular second primary molar Chronology Initial calcification months in utero Crown completion 10-12 months Eruption Root completion 3 years 6 Identifying features  Prominent bulge present buccally at cervical region Number of cusps: Number of pulp horns: Number of roots: 7
