2. Gingiva Root Canal Enamel Corona / Crown Radix / Root Cervix / Neck Dentin Occlusal Surface Anatomy of a Tooth Pulp

3. Tooth Numbering Fax sheet with tooth numbers Distinguish between primary and secondary numbers –Secondary full set = 32 teeth –Primary full set = 24 teeth Count 3rd molars (wisdom teeth) even if not present

4. Types of Teeth Incisor A tooth with a cutting edge (8) Central vs. lateral Anterior

5. Cuspid/Canine –A tooth with 1 point (4) –Anterior Type of Teeth

6. Bicuspid/Premolar –A tooth with 2 cusps (8) –Posterior Types of Teeth

7. Molar –Grinding tooth with multiple cusps (12) –First Molar –Second Molar –Third Molar – Wisdom Teeth Types of Teeth

8. Dental Terms To the front To the back A pronounced point on the surface of the tooth A groove on the surface of the tooth (posteriors) A sharp pointed depression on the surface of the tooth Anterior Posterior Cusp Fissure Pit

9. Dental Terms Occlusal - the top surface of posterior teeth (premolars & molars) Incisal - the surface edge of anterior teeth (incisors & canines) Interproximal – the surface between two teeth Mesial – the tooth surface toward the midline of the mouth Distal – the tooth surface toward the posterior of the mouth Labial – the tooth surface facing the lips (anterior) Buccal – the tooth surface facing the cheek (posterior) Lingual – the tooth surface facing the tongue

10. Cavity Classes 101

11. Cavity Classes 5 Classes of Cavities (Caries) I, II, III, IV, V Named by location on tooth surface and whether tooth is anterior or posterior

12. Applies to Class I & Class II O (Occlusal) MO (Mesio-Occlusal) DO (Disto-Occlusal) MOD (Mesio-Occlusal Distal)

13. Class I Fillings in fissures and pits. They are located on the occlusal surface of premolars and molars Cavity Classes Occlusal

14. Class II Fillings in posterior teeth (premolars,molars), including the interproximal surface. Cavity Classes DO MOD

15. Class III Fillings on anterior teeth that are on the interproximal surface. Cavity Classes

16. Class IV Fillings on anterior teeth that include the incisal edge and interproximal surface Hockey injury Cavity Classes

17. Class V Fillings on the cervical third of both anterior and posterior teeth (e.g. Gingival area) Cavity Classes

18. I II III VI V Cavity Classes
