16
Q

Why do we opt to extract teeth suffering from extrusion injury

A

As usually interfered with occlusion and becomes non vital

17
Q

What are the treatment options for intrusion injuries to primary teeth

A

Leave or extract

18
Q

what do we use to aid our decision to leave or extract an intrusion injury

A

Lateral radiographs to determine relationship of primary tooth to permanent successor

19
Q

When do we opt to extract an intrusion injury

A
  1. If there is a clear interface with the permanent successor
  2. If the primary tooth is infected
  3. If there has been failure to re erupt within 3-6 months
20
Q

How do we treat a primary tooth that has been avulsed

A

DO NOT RE IMPLANT

21
Q

What can fractures of primary teeth be split into

A
  1. No pulp exposure

2. Pulp exposure

22
Q

How do we treat a primary tooth fracture with no pulpal exposure

A

Leave and smooth over

Can do a composite restoration or strip crown

23
Q

How do we treat a primary tooth fracture with pulpal exposure

A

Extraction

Pulpotomy/pulpectomy

24
