1

Most common cause of tooth surface loos in children?

Erosion

2

Describe erosion clinically?

Silky/glassy appearance
Bucco-lingual/palatal flattening
Dished out occlusal appearance
Dentine exposure and high enamel ridges

3

What is erosion?

Chemical dissolution of tooth substance without presence of dental plaque

4

What is intrinsic erosion?

Gastric acid - vomiting, reflux, burping

5

What is extrinsic erosion?

Dietary

6

What is attrition?

Tooth to tooth contact without presence of food - teeth grinding

7

What is abrasion?

Friction of exogenous material forced over surface of tooth

8

Risk factors for tooth wear

Fizzy drinks frequently
Chronic medical conditios - taking oral medications with erosive potential
Xerostomia, head and neck radiation
Alcoholics
GI and eating disorder

9

How is tooth surface loss menagaed?

Genrally 'wait and see' especially if no pain/sensitivity, aesthetic or functionality concerns
Record --> study casts, photographs, dietary analysis, OHI

10

How can you reduce sensitisation of eroded teeth?

Fluoride varnish, toothpastes
ACP (amorphous clacium phsophate) - chewing gum, mousse
Sensodyne

11

Treatment objectives for TSL?

Resolve sensitivity
Restore missing tooth surface
Prevent further tooth loss
Maintain a balanced occlusion

12

Operative treatment of TSL (primary teeth)?

Cover with composite resin and/or stainless steel crowns
Extract offending teeth

13

Operative treatment of TSL (permanent teeth)?

Treat conservatively = long term monitoring and composite resin to eroded surfaces
Dentien binding can offer short-lived dentine protection
