1. Connecting Element
2. If in a Fixed Bridge (the teeth Supporting Bridge)
3. If in a Partial Removable Denture (the teeth Supporting Partial)
4. If in a Implant (the teeth attach to a Crown, Bridge, Removable Denture)

Question 3

Acute Necrotizing Ulcerative Gingivitis (ANUG)

Answer 3

1. A Microbial Inflammatory Destructive Dx. of Gingiva
2. Impaired Host Response (chara: Death & Sloughing of Gingival Tissue)
3. ANUG occurs when harmful bacteria OVERGROW in the mouth, particularly in the GUM TISSUE. This usually happens due to factors such as poor oral hygiene, stress, a weakened immune system, smoking, or nutritional deficiencies.

1. Benign/Cancerous Tumour of ODONTOGENIC EPITHELIUM
2. More common @ Lower下 Jaw

Question 8

Anachoresis

Answer 8

1. Localization of Blood-borne Bacteria @ Pulp
2. Thus, Pulp become Necrotic when there’s no Etiologic Fx.

Question 9

Angle’s Normal Occlusion

Answer 9

Mesiobuccal Cusp of Upper 1st Molar OCCLUDES w/ Buccal Groove of Lower 1st Molar

Question 10

Angle’s Class I Malocclusion

Answer 10

1. Same w/ Normal Occlusion
2. Crowding, Rotations, Other Positional Irregularities

Question 11

Angle’s Class II Malocclusion

Answer 11

Mesiobuccal Cusp of Upper 1st Molar OCCLUDES anterior to Buccal Groove of Lower 1st Molar

The 2 Subtypes of AC II M:
1. Upper Incisors - Tilted OUT (Overjet)

Question 12

Angle’s Class III Malocclusion

Answer 12

Mesiobuccal Cusp of Upper 1st Molar OCCLUDES posterior to Buccal Groove of Lower 1st Molar

Question 13

Anterior Deep Overjet

Answer 13

• Extent of Horizontal Overlap of Maxillary Central Incisors over the Mandibular Central Incisors
• Normal Overjet - 2-3 mm
• Overjet >3mm - more likely to suffer injury to their upper incisors

Question 14

Anterior Deep Overbite

Answer 14

Excessive overlap of Upper Front Teeth (Incisor) OVER Lower Front Teeth when the Jaws are closed. It may be the result from Upward and Forward Rotation of Mandible during growth or from Excessive Eruption of Incisor Teeth

Answer 17

1. For Dx. Periodontal Disease
2. Indicate - Gingival Inflammation
3. For proper Dx. should combine BOP with Probing Depth, Clinical Attachment Loss

Carcinoma In Situ**

Answer 19

Precancerous condition where Abnormal Cells are found ONLY in the SURFACE layer of the ORAL tissues.

Question 20

Cementum

Answer 20

Specialized tissue that COVERS the ROOTS of teeth. It plays a crucial role in ANCHORING the teeth to the JAWBONE through the attachment of tiny fibers called PERIODONTAL LIGAMENTS.
