Q

what can be the issue with the oral end of the incisive canal on a radioluscency

A

it can be projected over the apex of the central incisors and can resemble an inflammatory cyst but usually this is much bigger

Q

what can be the issue with the canine fossa

17
Q

what lies anterior to the hamulus

A

is the hamular notch

18
Q

why is the hamular notch important

A

as when making dentures we should extend the denture in this area as the soft tissue can give

19
Q

what is the maxilla tuberosity

A

it is the area of the maxilla posterior the last molar and associated with the third molar

20
Q

what is highlighted

A

the coronoid process

Q

which structure is circled

A

the deal duct or the nasal lacrimal duct

22
Q

what structure is highlighted

A

the neuro vascular channals

23

what is this structure

A

the mental foramen- seen where the IAN enters and divides into the incisive nerve to supply the lower anterior teeth
