1. Introduction T o Operative D entistry Presented By- Dr. ANURAG JAIN

2. DEFINITION “ Operative dentistry is the art and science of the diagnosis ,treatment and prognosis of the defects of teeth that do not require full coverage restorations for correction. Such treatment should result in the restoration of proper tooth form, function and esthetics while maintaining the physiologic integrity of the teeth in harmonious relationship with the adjacent hard and soft tissues, all of which should enhance the general health and welfare of the patient ”

3. INDICATIONS: Caries Malformed, discolored, nonesthetic teeth fractured teeth & Restoration,replacement or repair. Non carious lesion (attrition, abrasion, abfraction ).

4. Considerations Infection control. Thorough examination of oral and systemic health of patient. A diagnosis of dental problem that recognizes interaction of affected area with other body tissues. A treatment plan that has the potential to return the affected area to a state of health and function, enhancing the overall health and well-being of the patient

5. Tooth N umbering S ystem The combined primary and deciduous dentition result in a total 52 teeth a clear and convenient means of identification of specific teeth is necessary . There are several systems which are proposed for tooth numbering system .

6. The 3 popular system which are currently popular. They are :- 1 Zsigmondy / Palmer system 2 American Dental Association (ADA) system or Universal Numbering system 3 Federation Dentaire International (FDI) System

7. Zsigmondy/Palmer System It is oldest system also called as Grid or Angular system. In this system Primary Dentition are denoted by English Upper case Latter and Permanent Dentition are denoted by Number

8. EDCBA ABCDE EDCBA ABCDE 87654321 12345678 87654321 12345678

9. ADA System or Universal System The Primary Dentition are denoted by consecutive english upper case latter starting from maxillary 2nd Molar. The Permanent Teeth are indicated by number 1 to 32 .

10. FDI System it is also referred as Two Digit System. The first digit identifies the Quadrant to which tooth belong and second digit denotes the tooth. Both digit have to be pronounced separately. for Permanent Dentition Quadrant are numbered 1 to 4 and tooth are numbered 1 to 8 from the midline for Deciduous dentition the quadrant are 5 to 8 and teeth are denoted 1 to 5 from the midline

11. Terminology related to various tooth surfaces The coronal portion of tooth is divided into surface. Mesial : The surface of the tooth closest to the anterior midline. Distal: The surface of tooth away from the anterior midline. labial: The surface of the tooth toward the lip. Buccal : The tooth surface that is towards the cheek Facial: The surface of tooth towards patients face

12. Lingual:The tooth surface that is towards the tongue. Incisal:The Functional edge of an anterior tooth. Occlusal:The masticating surface of a posterior tooth Cervical:The surface of the tooth close to the neck or cervix of tooth. Gingival:The surface of the tooth close to the gingiva .

13. Dental Anatomy and Physiology  In humans we have 2 sets of teeth •Primary (deciduous) •Secondary (permanent)

14. Classification of Teeth Incisors (central and lateral) Canines ( cuspids ) • Premolars (bicuspids) Molars
