Oral surgery L7: management of the spread of infection

Question 1

Q1: what determines the sequelae (condition which is consequence of a previous disease) of infection?

Answer 1

1. Virulence of the organism involved.
2. Host resistance to infection (local and systemic).
3. Local anatomy.
4. Treatment of infection

Question 2

Q2: antibiotics are successful when they are in the blood stream and target the site of infection. Why would antibiotics not be successful in a non vital tooth?

Answer 2

In a non-vital tooth, there is no vasculature, so the bacteria that are residing in the tooth will not be affected by the antibiotic.

Question 3

Q3: why cant antibiotics treat endogenic infections?

Answer 3

Endogenic infections will have eliminated the vasculature that supplies the pulp, therefore antibiotics can not reach the bacteria.

Question 4

Q4: how does the apex of the tooth determine the spread of infection?

Answer 4

Depending on the roots position, would determine where the pathogens migrate to such as the buccal sulcus, maxillary sinus, antrum, nose, and palate

Question 5

Q5: which condition is the inflammation of the soft tissues, which is not circumscribed or confined to one area but tends to spread through tissues spaces along fascial planes?

Answer 5

Cellulitis

Question 6

Q6: what is odontogenic infection?

Answer 6

Odontogenic infection is an infection of the alveolus, jaw, or face that originates from a tooth or from its supporting structures

Question 7

Q7: principles of management of odontogenic infection would be to eliminate the cause of the infection? How would you do this?

Answer 7

If the patient wishes to keep their tooth, then extripate the pulp and perform root canal. If the patient does not want to keep the tooth, then an extraction.

Question 8

Q8: when managing odontogenic infection how would you provide a path of least resistance?

Answer 8

Through incision and drainage.

Question 9

Q9: if you have eradicated the source of infection, then antibiotics would not be appropriate, when would you only prescribe antibiotics once you have removed the source of infection?

Answer 9

When the patient is immune compromised.

Question 10

Q10: if pus is allowed to track through the alveolus and form a sinus and eventually erupt through the mucosa, what would that indicate in terms of infection?

Answer 10

That the infection is a chronic.

Question 11

Q11: what is the name of this condition?

Answer 11

Orocutaneous fistula

Question 12

Q12: which tooths root is long enough to pass muscles of facial expression?

Answer 12

Canines root

Question 13

Q13: if you have swelling in the sub mandibular space, would you be allowed to perform incision and drainage in primary care?

Answer 13

No you would not, only in the sub lingual space.

Question 14

Q14: the sub mental space usually gets infected through which tooth?

Answer 14

Lower incisors.
