Answer 8

Inflammation of periodontal ligament
Apical periodontitis
Periapical space of black: cell rests of Malassez

Question 9

Subacute periodontitis Caracteristique

Answer 9

1-Serous
2-Overgrown tooth sensation
3-Slight edema
4-Tooth discoloration
5-Light pain upon percussion
6-Rx = neg
7-Non-spontaneous pain
8-Vitality test = positive

Question 10

Acute periodontitis:
Serous form

Answer 10

1-Light movement
2-Overgrown tooth sensation
3-Tooth discoloration
4-Pain upon percussion
5-Rx negative
6-Spontaneous pain
7-Vitality test= neg
8-Dull percussion sound

Question 11

Acute periodontitis:
Suppurative form

Answer 11

1-Periapical abscess , periapical Osteitis
2-More pronounced symptoms and malaise (virulence, reduced host defenses, trauma)
3-Vitality negative+pus

Question 12

Chronic periodontitis:
Callous type

Answer 12

Fibrous tissue not localized (healing)

Question 13

Chronic periodontitis:
Granuloma type

Answer 13

1-Hyperplastic defensive inflammatory periapical lesion
2-Slight/Weak but continuous/repeated stimulus
3-No symptoms
4-Rx: appearance of periapical or lateral radiolucency
5-Destruction of cement, plate, and bone
6-Darker area: Radiolucency
7-Malassez-Epithelial Granuloma-Cysts

Question 14

Cellulitis = Phlegmon

Answer 14

1- Inflammation of the soft tissue of the mouth, face, and neck
2-Tooth_Bone-Soft tissue_Mediastinum
3-On palpation: Hard and doughy edema
4-Not localized infection, there are no anatomic limits
5-There is no tissues destruction, there’s no suppuration
6-Periodontitis - osteitis-periostitis-cellulitis-septicaemia)
7-Chronic: Granuloma, cysts ,fistula

Question 15

Abscess

Answer 15

1-When the host’s defense is failing or increased virulence of the micro-organism
2-Sudden appearance of localized suppuration
3-Limited/with boundaries
4-Sudden appearance in any cervicofacial area

Question 16

Abscess: Clinical manifestations with much emphasis

Answer 16

1-Red swelling
2-Less pain (The organism is fighting the infection)
3-Fluctuation
4-Fingerprint sign
5-Functional and Bad condition

Question 17

FACTORS THAT INFLUENCE THE SPREADING OF INFECTION

Answer 17

• Suppuration in the periodontal space (viewed )
• Direct dissemination from lymphatic, venous or parulic route (sub-periostic)
• Systemic diseases decreasing defenses

Question 18

GENERAL FACTORS THAT INFLUENCE THE SPREADING OF INFECTION

Answer 18

• Balance between resistance and agressiveness
• Host resistance: Humoral and cellular defense- Bacterial action
• Aerobic

Question 19

MICROORGANISMS INVOLVED IN MIXED BACTERIAL INFECTIONS OF THE ORAL CAVITY

Answer 19

The odontogenic infection is ,biologically dinamic , polymicrobialand can be mixed with predominatinganaerobic flora

Question 20

LOCAL FACTORS THAT INFLUENCE THE SPREADING OF THE INFECTION

Answer 20

• Socket situation and cortical plate thickness
• Root length and attached mucose
• Muscle insertions-
• Movements of the region
• Anatomic spaces and aponeurotic layers (fascia)
• Anatomic regions

Question 21

If the apex is higher than the insertion

Answer 21

Up to the buccal vestibule
