DEVELOPMENTAL DISTURBANCES OF JAWS

SLIDE NO.1 Identify this developmental disturbance of jaws

MICROGNATHIA Micro=small

Gnathia=jaws

In this case mandible is underdeveloped, giving BIRD FACIES APPEARANCE.

SLIDE NO.2 Identify this developmental disturbance of jaws

MACROGNATHIAMacro=large

DEVELOPMENTAL DISTURBANCES AFFECTING TEETHSIZE

SHAPENUMBER

STRUCTURE

DEVELOPMENTAL ANOMALIES AFFECTING SIZE OF TEETH

SLIDE NO.3 Identify the following tooth anomaly

PEG LATERAL

It is a localised form of MICRODONTIA

localised=limited to 1 or 2 teethdontia=teeth

DEVELOPMENTAL ANOMALIES AFFECTING SHAPE OF TEETH

SLIDE NO.4 Identify the teeth anomaly

GEMINATION

One tooth germ is divided into two teeth.

Clinically it shows two crowns and one root.

SLIDE NO.5 Identify the teeth anomaly

FUSIONTwo teeth germs fuse with each

other.

Clinically it shows two crowns and two roots fused .

SLIDE NO.6 Identify the teeth anomaly and write the clinical complications of it

cementum

CONCRESCENCE

Teeth are fused to each other by cementum

Clinical complications:fracture of teeth during extraction

SLIDE NO.7 Identify the teeth anomaly and write the clinical complications of it

DIALACERATIONsharp bend in the tooth at crown or root level

Clinical complications:fracture of tooth during extraction

SLIDE NO.8 Identify the teeth anomaly and write the clinical complications of it
