3 months

26

Basketball 🏀

27
Q

What is the Minimum adequate thickness for a mouthguard?

A

3mm

28
Q

What arch should a mouth guard be made for?

How many teeth should it cover?

What is the exception?

A

Should cover all the teeth all the teeth in th arch (except 3rd Molars)

Maxillary arch in most all cases

Class III, Mandibular arch*

29
Q

What type of suture material do you want for deep lacerations?

Why?

A

You want ABSORBABLE sutures:

VICRYL sutures: Absorbable

Silk and Nylon: Non-absorbable

30
Q

What is the difference in clinical findings between a human bite and a dog bite?

A

HUMAN BITES:

Compress the tissue causing contusion, abrasions, and lacerations of tissue.

DOG BITES:

Cause avulsion of tissue.

31
Q

What are mouthguards by type?

What is the most common?

A

Type 1: Custom Fit (Best)

Type 2: Boil and Bite (most common)

Type 3: Stock Mouthguards (must be held in place my clenching teeth together to have any benefit)

32
Q

What is the most common complication on Permanent Teeth in INTRUSION Trauma

A
  1. Pulp necrosis (Closed Apex)

1. PCO (Open Apex)

33
Q

What is the most common complication in permanent teeth in EXTRUSION trauma?

A

Pulp Necrosis

PCO

34
Q

What is the most common PRIMARY trauma?

A

Luxation

35
Q

What is a complication that cannot be treated Avulsion?

A

Replacement resorption, ANKYLOSIS

36
Q

When do you expect to see a periapical lesion after trauma?

A

Depends what kind of trauma

3 weeks

37
Q

What is the initial action in wound healing?

A

Platelet Aggregation

38
Q

What is the most common material used in making mouthguards?

A

EVA

Ethylene-Vinyl-Acetate

39
Q

Which sports requires the use of a mouthguard?

A

Hockey 🏒

Lacrosse

Wrestling 🤼‍♀️

40
Q

When is tetanus needed when suffering ma dirty wound?

A

If not within 5 years

If needed give booster within 48 hours

According to WHO:

The type of tetanus prophylaxis that is required following injury depends on the nature of the lesion and the history of previous immunizations. However, no booster is needed if the last dose of the primary series, or of subsequent booster injections, was given less than 5 years ago for dirty wounds or less than 10 years ago for clean wounds.

41
Q

Long term complications of a burn injury?

Treatment?

A

Microstomia

Appliance needed to prevent contracture

Worn 6-12 months

Edema: May last a week, eventually necrotic tissue will slough off in 3 weeks

42
Q

What suture would you use if tension-less contact is impossible?

A

Mattress suture

The horizontal mattress suture is an everting suture technique that spreads tension along a wound edge. This technique is commonly used for pulling wound edges together over a distance, or as the initial suture to anchor two wound edges (holding sutures).

The advantages of the vertical mattress suture are that it provides closure for both deep and superficial layers, and also allows perfect eversion and vertical opposition of the superficial skin edges.

43
Q

If a laceration is through and through, what do you suture first?

A

Muscle

44
Q

If a tooth is avulsed (Central maxillary incisor) when should you do a interdental Transplant (autotransplantation)

A

When root is 3/4 formed

Autogenous tooth transplantation, or autotransplantation, is the surgical movement of a tooth from one location in the mouth to another in the same individual. Once thought to be experimental, autotransplantation has achieved high success rates and is an excellent option for tooth replacement.

Autotransplantation of teeth with an immature open root apex is more favourable than those with a closed root apex.

Usually, mandibular first or second premolars are appropriate in mesiodistal dimension to replace lost central incisor, although later an adequate reconstruction of the crown with composite resin or artificial crown according to anatomy is needed.

45
Q

In a laceration involving the skin, mucosa, and inside oral tissue,which do you suture first?

A

Skin first

46
Q

Why is water a bad storage medium for an avulsed tooth?

A

Hypotonic

A hypotonic solution is any solution that has a lower osmotic pressure than another solution. In the biological fields, this generally refers to a solution that has less solute and more water than another solution.

where the solution outside the cell has a lower solute concentration than the cell fluid, water will move into the cell towards the higher solute concentration. The less concentrated outside solution is termed hypotonic.

47
Q

In a subluxation trauma, where the tooth is mobile but not displaced, what is the recommended treatment?

A

2 week splint

48
Q

Most predictive of Pulp always necrosis in a crown fracture?

A

Concomitant LUXATION injury

The primary factor related to pulp healing events after crown fracture appears to be COMPROMISED PULP CIRCULATION due to concomitant luxation injuries.

An associated damage to the periodontal ligament significantly increased the likelihood of pulp necrosis from 0% to 28%

49
Q

Which suture causes the most inflammation?

A
  1. Silk (braided)

Followed by chromic/gut/vicryl

Lastly, polypropelyne.

50
Q

Most common crown fracture in primary dentition?

A

Enamel only

51
Q

Adult bite inter-canine width?

A

3 cm

52
Q

Where is the most common jaw fracture in children?

A

Condole

53
Q

Soft tissue injury that removes pieces of tissue is called?

A

Avulsion
