Managing Avulsed Teeth and Treatment Outcomes

This video tutorial covers the management of tooth avulsion, a common dental injury where a tooth is completely displaced from its socket. It discusses the causes, classification, and management strategies based on the extra-oral dry time of the avulsed tooth. The video also provides guidance on re-implantation at the site and emphasizes the importance of follow-up to assess treatment success or failure. Special storage media for preserving the tooth and the prognosis of different treatment approaches are also explained.

What is the term used to describe the complete displacement of a tooth from its socket?

• Tooth fracture

• Tooth decay

• Tooth avulsion

• Tooth erosion

Which teeth are most commonly affected by avulsion injuries?

• Mandibular molars

• Maxillary central incisors

• Mandibular canines

• Maxillary premolars

Why is it important to minimize the extra-oral dry time of an avulsed tooth?

• To avoid tooth sensitivity

• To reduce the risk of infection

• To improve the prognosis of re-implantation

• To prevent tooth discoloration

Which of the following is NOT a recommended storage medium for an avulsed tooth?

• Milk

• Coconut water

• Tap water

What is the first step in managing an avulsed tooth with less than 60 minutes of extra-oral dry time?

• Suture the gingiva

• Administer local anesthesia

• Perform a root canal treatment

• Apply a flexible splint

What is a potential long-term outcome for a tooth with more than 60 minutes of extra-oral dry time?

• Ankylosis

• Increased tooth length

• Tooth whitening

• Improved tooth strength

What should be done if a tooth is re-implanted at the site of injury?

• Use a permanent splint

• Check the tooth's position and clean the site

• Perform immediate root canal treatment

• Apply fluoride varnish

How often should follow-up visits occur in the first year after avulsion treatment?

• Every day

• Once a month

• Once a year

• Every three months

What is a sign of a favorable outcome after avulsion treatment?

• High-pitched percussion sound

• Tooth discoloration

• Normal tooth mobility

• Excessive tooth mobility

What radiographic feature indicates an unfavorable outcome in a closed apex tooth?

• Continued root formation

• Root resorption

• Arrested root formation

• Normal lamina dura
