How does external inflammatory resorption occur through trauma?
External inflammatory resorption is one of the potential consequences of trauma to the teeth. It occurs when there has been a loss of cementum due to damage to the external surface of the tooth root during trauma, along with the root canal system being infected with bacteria.

133
How would you manage lateral luxation of the permanent teeth?
1. Any exposed root surface should be cleaned with saline prior to repositioning
2. Local anaesthesia is required
3. Gently reposition the tooth with forceps or digital pressure to disengage it and gently reposition it into its original location. Pre trauma photos are useful for guiding this.
4. Stabilize the tooth for 4 weeks using flexible splint. 4 weeks is indicated due to associated bone fracture. Care must be taken when removing the splint to ensure that the tooth is no longer abnormally mobile

Using MTA
144
How much MTA should be used as a plug?
5mm

Pulp necrosis occurs in about 20% of root fractures, the greater the amount of initial displacement, the greater the chance of necrosis. The root apical to the fracture usually retains vitality, how do you treat this?
1. Apical 1/3 and mid 1/3 root fractures, treat up to the point of the fracture – do not extend beyond the fracture into apical portion.
2. MTA apical stop may be required at the fracture line
3. If apical portion becomes non vital, may require surgical removal
146
Which type of dentine is responsible for permanent tooth pulp canal obliteration?
Reactionary dentine
147
Multi nuclear giant cells are responsible for what when they are stimulated as part of the inflammatory response?
Inflammatory resorption.
148
External inflammatory response occurs with teeth that have both?
Necrotic pulps and associated infection.
149
In external resorption, the giant cells are activated in the?
Activated in the PDL, and the stimulus is the infected canal
150
When does ankylosis usually occur?
Usually occurs after large luxation or avulsion injuries. When more than 20% of the PDL is damaged before replanting or repositioning, then bone cells are able to colonize the surface of the root faster than the PDL.
151
What two vitality testing do we not do on primary tooth?

2. Thermal testing
152
What is the purpose of doing a pulpotomy technique?
A (vital) pulpotomy is a technique used for managing the traumatised permanent incisor where there is an enamel/dentine fracture and a pulpal exposure. The purpose is to remove (amputate) infected and inflamed pulp tissue. The remaining healthy pulpal tissue surface is then treated with calcium hydroxide or MTA. The objective of this procedure is to maintain the tooth’s vitality and also allow the root to continue development in the case of immature teeth.

How would you arrest the bleeding in a pulpotomy?
Arrest the bleeding using a cotton wool pledget soaked in sterile water/saline. Adrenaline free local anaesthetic can be used as an alternative to sterile water/saline. Do not use water from the 3 in 1 syringe!
154
What would you dress the exposed pulpal surface with in a pulpotomy?
Dress the exposed pulpal surface with calcium hydroxide or MTA or other non-staining calcium silicate cements.
155
What would use to cover the dressing of calcium hydroxide or MTA in a pulpotomy?
Cover the calcium hydroxide or alternative with resin modified glass ionomer cement. This functions as a lining in preparation to receive composite restoration immediately.
156
What is a composite bandage used for?
A composite bandage is a temporary dressing placed on a tooth immediately after an enamel dentine fracture or an enamel dentine pulp fracture that has undergone a pulpotomy.
157
We must be careful not to splint teeth for too long as this can lead to?
Ankylosis or external resorption
