1. ANOMALIES OF TOOTH DEVELOPMENT

2. SUPERNUMERARY TEETH Mesiodens malformed, peg-like tooth that occurs between the maxillary central incisors Very rare case Most common supernumerary teeth

3. SUPERNUMERARY TEETH Paramolars Supernumerary molars adjacent to the normal molar, situated buccally , lingual or palatal or in the inter proximal space Mesiomolar / Distomolar – located mesial or distal to molar

4. ANODONTIA TRUE ANODONTIA TEETH ARE MISSING CONGENITALLY BECAUSE TOOTH GERMS DID NOT DEVELOP PSEUDO ANODONTIA - TEETH ARE MISSING CLINICALLY BUT THEY WER FORMED AND FAILED TO ERUPT HYPODONTIA - DENTITIONS WITH FEWER TEETH THAN NORMAL DUE TO AGENESIS OF DENTAL GERM OR FAILURE OF THE DENTAL GERM TO FULLY DEVELOP OLIGODONTIA - ABSENCE OF MORE THAN SIX TEETH IN PRIMARY, PERMANENT OR BOTH AND THE REMAINING ARE SMALLER

5. FREQUENCY OF MISSING TEETH 3 rd Molars 2 nd PREMOLAR (LOWER) 3. UPPER LATERAL INCISORS 4. LOWER CENTRAL INCISORS 5. LOWER LATERAL INCISOR S

6. GEMINATION - A CONDITION IN WHICH A SINGLE TOOTH GERM DIVIDES DURING THE PERIOD OF TOOTH FORMATION AND FORMS A DOUBLE CROWN WITH A SINGLE ROOT AND ROOT CANAL FUSION - A CONDITION IN WHICH TWO NORMAL SEPARATE TOOTH GERMS BECOME UNITED CONCRESCENCE - A FORM OF FUSION IN WHICH THE UNION IS ONLY IN THE CEMENTUM OF ADJACENT TOOTH AND OCCURS AFTER THE RROT FORMATION HAS BEEN COMPLETED

7. MACRODONTIA - ABNORMALLY LARGE TOOTH MICRODONTIA - ABNORMALLY SMALL TOOTH DENS INVAGINATUS - DEEP INVAGINATION OF THE LINGUAL PIT OF AN INCISOR INTO THE REST OF THE CROWN TALON CUSP - EXTRA CUSP ON ANTERIOR TOOTH - HORN LIKE PROTUBERANCE PROJECTING FROM THE LINGUAL SURFACE

8. TAURODONTISM - BODY OF THE TOOTH AND PULP CHAMBER IS ENLARGED VERTICALLY AT THE EXPENSE OF THE ROOTS. - AS A RESULT, THE FLOOR OF THE PULP AND THE FURCATION OF THE TOOTH IS MOVED APICALLY DOWN THE ROOT DILACERATION -ANGULAR POSITION BETWEEN THE TWO PARTS OF A TOOTH
