Dental Traumatology

Injuries to primary teeth most comonly occur during

• 6-12 months

• 3-4 years

• 3-6 years

• 1.5-2.5

A 11 yr old child comes to the dental office one hour after injury to maxillary central incisor. Tooth is vital and slightly mobile. Radiographic examination reveals fracture of apical third of root. What is the best treatment plan?

• Render palliative therapy

• Extract the tooth

• Relieve occlusion and splint the tooth

• Perform root canal and splint

A 7 yr old child reports of fracture of central incisor with open apex with large pulpal exposure. Treatment of choice is

• Extract

• Root Canal treatment

• Pulpotomy

• Direct Pulp capping

3 yr old child has sustained fracture in central incisor one month ago. On examination necrotic pulp was seen with no other pathologic findings. Treatment of choice is

• Wait and watch

• Extraction

• Pulpectomy

• Strip Crown

Child with tooth that was avulsed 1. 5 hours back should carry tooth in

• Cold Milk

• Normal Saline

• Wet Handkerchief

• Buccal Vestibule

A permanent tooth bud which is accidentally removed during extraction of primary tooth should be

• Discarded

• socket curreted and tooth bud replanted

• pulpectomy of tooth bud

• Place into socket from where it was removed

8 year old child has intrusion of permanent maxillary incisors. The choice of treatment is

• Put tooth in place and splint

• Allow tooth to erupt on its own

• treat orthodontically

• no treatment

Exarticulation of teeth means

• Intrusion

• Extrusion

• Subluxation

• Avulsion

The change in colour of a traumatized primary tooth occurs due to all except

• laceration of PDL fibres

• Diffusion of biliveridin into dentinal tubules

• development of heavy layer of sclerotic dentin

• internal resorption of dentin within the crown

In root fracture of apical third of permanent anterior teeth, anterior tooth is

• discolour rapidly

• Remain in function and vital

• Undergo Pulpal necrosis and become ankylosed

• Indicated for extraction and prosthetic replacement
