1
Q

Lingually Displaced Mandibular Canine Teeth

A

unilateral or bilateral
often with with mandibular distclusion (short mandible)
can be painful
will result in extensive palatal defects if left untreated

2
Q

mixed dentition - define

A

during teething - mix of deciduous + permanent

3
Q

persistent deciduous tooth - define

A

temp tooth still there when permanent tooth has already erupted

4
Q

persistent deciduous tooth - treatment

A

dental radiograph - if resorption present
extraction
long thin roots prone to fragmentation

5
Q

supernumerary teeth

A

often incisor/premolar teeth
crowding can cause periodontal disease - extract more abnormally positioned teeth
some supernumeraries only a cosmetic issue

6
Q

missing teeth causes

A

hypodontia - congenital absence
impacted or embedded tooth - no eruption
traumatic crown fracture below gingival margin
diagnose by radiograph

7
Q

enamel hypoplasia

A

enamel develops prior to eruption - hypoplastic enamel

noxius event during tooth development + before eruption

8
Q

abrasion

A

tooth surface wears against abrasive objects

can cause reparative dentin or pulp exposure if fast

9
Q

attrition

A

tooth on tooth wear

can cause reparative dentin or pulp exposure if fast

10
Q

fracture types

A
with pulp exposure
root 
crown + root
chip - no pulp exposure
pulpal blush - near pulp-exposure, pink point showing through dentin
11
Q

intrinsic staining

A

tooth discoloured from within - blunt trauma

12
Q

pulp exposure - test with sharp explorer

A

has a hole which tip of explorer will sink

13
Q

reparative dentin

A

hard continuous surface

sharp explorer shouldn’t stick or sink into

14
Q

commonly overlooked fracture

A

older slab fracture
often covered with calculus
calculus deposits quicker due to the rough surface
upper fourth premolar

15
Q

draining sinus tract - location

A

muco-gingival junction

can be explored with blunt probe

16
Q

can fractured teeth be left if no problem

A

nope
periapical pathology develops soon after trauma - abscess formation inevitable
pain can be v.severe

17
Q

what happens inside fractured tooth?

A

pulp exposure - microbial invasion - pulpitis - pulp necrosis
periapical pathology - bacteria try get into jaw bone + produce toxins
interactions of bacteria with immune response - pathological changes in jaw bone

18
Q

periapical radiolucency - appearance on radiograph

A

bulbous shape

loss of lamina dura

19
Q

treatment for fracture on 1st presentation

A

analgesia

antibiotics

20
Q

definitive treatment of fractured tooth

A

extraction
vital pulp treatment
root canal therapy

21
Q

oral mass lesions

A

neoplasia
hyperplasia, cyst, hamartoma
need biopsy + imaging

22
Q

impacted teeth

A

1st premolar most commonly affected
brachycephalics predisposed
high risk of cyst infection
