radicular teeth

A

The apices remain open for much of adult life, with later termination of continued growth. Occlusive wear is set off by eruption.

Intraoral Examination

A

Evaluation of the oral cavity soft tissue structures and teeth, including supporting structures (in other words, the periodontium).

The color and integrity of mucosal structures and gingiva are assessed. Also assessed are the hard and soft palates of the oral cavity.

31
Q

radiodense

A

x-rays don’t pass through them readily
cementum, dentin, bone

32
Q

Radiopaque

A

the term for anatomic structures that are radiodense (bone)

33
Q

Radiolucent

A

Corresponds to the radiographic appearance of soft-tissue structures (x-rays pass through more easily).

34
Q

periodontitis

A

The most common disease in animals
Bacterial plaque on a tooth’s crown surface affects the gingiva by exposing it to antigens (the bacteria), leading to an inflammatory response. Plaque on the tooth surface below the gingival margin (subgingival) leads to inflammatory responses that can result in damage to tissue and bone around the root.

35
Q

Four types of nerve blocks for oral cavity analgesia:

A

Infraorbital nerve blocks
Middle mental nerve blocks
Inferior alveolar nerve blocks
Maxillary nerve blocks

36
Q

Infraorbital nerve blocks

A

block the infraorbital and rostral maxillary alveolar nerves and provide analgesia to the incisors, canine, first three premolar teeth, maxillary bone, and the surrounding soft tissue.

37
Q

Middle mental nerve blocks

A

provide analgesia to the incisors and canine tooth of the corresponding side, as well as the adjacent bone and soft tissues.

38
Q

Inferior alveolar nerve blocks

A

Affect the entire ipsilateral mandible. Due to the resulting numbness of the tongue, self-trauma of the tongue can occur. Therefore, monitoring is necessary. A measure to prevent this is to use a small volume of anesthetic to prevent medial diffusion that can affect the lingual nerve.

39
Q

Maxillary nerve blocks

A

. Blocking affects the bones, teeth, and soft and hard palates. Cats and brachycephalic dogs don’t need this type of block because the infraorbital block affects the entire maxilla on the corresponding side due to these animals’ short infraorbital foramen.

40
Q

Grade I Dental disease

A

Is confined to gingivitis and can be reversed easily.

41
Q

Grade II Dental Disease

A

Early periodontitis and includes loss of gingival attachment. It may require subgingival curettage.

42
Q

Grade III Dental Disease

A

Moderate periodontitis, with 25%–50% loss of attachment. Curettage or surgery is needed; there’s a fair to guarded prognosis.

43
Q

Grade IV Dental Disease

A

Severe periodontitis, with 50% or greater attachment loss. Teeth require extraction.

44
Q

Doxycycline gel

A

Has antimicrobial and anti-inflammatory effects
May be applied to a freshly debrided periodontal pocket.

45
Q

If the pocket depth remains more than 5 mm for 2 to 4 months after treatment:

A

The defect can be corrected surgically. This entails the creation of a flap and root planing.

46
Q

Osteoconductive

A

Can be used to correct bone loss defects
Material acts as scaffolding for new bone cells.

47
Q

Osteoinductive

A

Material stimulates osteoblast progenitor cell differentiation, leading to new bone formation.

48
Q

Tooth resorption

A

Rare in dogs, but it’s common in cats. Lesions begin on the root surface and often are observed at the cervical region of the tooth. Tooth extraction is the treatment of choice.

49
Q

Endodontics

A

The treatment of the tooth interior and periapical tissues.

Includes root canal therapy for dogs and cats that are 12 months of age.

50
Q

Root Canals

A

Involves removing dead or dying pulp, shaping the root canal, and filling the canal to seal the apex.

51
Q

Exodontics

A

Treatment of dental pathology via tooth extraction.

52
Q

Closed tooth extraction

A

Used for single-rooted teeth that have severe periodontal disease. Soft tissue attachments are severed, and an elevator is used to apply pressure to loosen the tooth for removal with a larger instrument.

53
Q

Surgical extraction (dental)

A

Involves also severing gingival attachments and creating a mucoperiosteal flap by making two full-thickness incisions through the mucosa and periosteum.
The roots of multirooted teeth are sectioned with a burr and handpiece. The root pieces are then gently pried from the socket. Rough bone edges are smoothed with a diamond burr, the alveolus of the root is curetted and lavaged, and the defect is closed with suture.

54
Q

Gingivitis

A

Inflammation of the gingiva (gums)

55
Q

subgingival

A

Below the gum line

56
Q

What may be applied to a freshly debrided periodontal pocket.

A

Doxycycline gel

57
Q

Osteoconductive

A

Material that acts as scaffolding for new bone cells. It stimulates osteoblast progenitor cell differentiation

58
Q

Four classes of malocclusions

A

Class I, neutroclusion,
Class II, mandibular distoclusion
Class III, mandibular mesioclusion
Class IV, maxillomandibular asymmetry

59
Q

Class I Malocclusion

A

Neutroclusion, is characterized by normal maxillary and mandibular dental arch relationships, with malposition of one or more individual teeth. These are the most common in pets.

60
Q

Class III Malocclusion

A

Underbite
mandibular mesioclusion, is characterized by occlusion in the mandibular arch rostral to its normal position relative to the maxillary arch.

61
Q

Class II Malocclusion

A

Overshot

Mandibular distoclusion, occlusion in the mandibular arch caudal to its normal position relative to the maxillary arch.

62
Q

Edit Class IV Malocclusion

A

Maxillomandibular asymmetry, is characterized by asymmetry in a rostrocaudal, side-to-side, or dorsoventral direction.

63
Q

An endodontic problem commonly seen in horses and it’s treatment

A

Tooth root abscesses.
Antibiotics are administered for temporary treatment, but surgery or endodontic treatment provides better prognoses.

64
Q

Parrot mouth and treatment

A

Characterized by a mandible that’s shorter than the maxilla in horses. This malocclusion caused by abnormal development, wear, or eruption.

The main treatment goal for orthodontic abnormalities is to prevent abnormal wear on the teeth.

65
Q

Monkey mouth and treatment

A

Characterized by a maxilla is shorter than the mandible. This malocclusion caused by abnormal development, wear, or eruption.

The main treatment goal for orthodontic abnormalities is to prevent abnormal wear on the teeth.

66
Q

Wry nose

A

A lateral deviation from the midline of the incisive bone, maxilla, and nasal septum, is a problem seen in foals. These foals may have trouble suckling or grabbing forage. The nasal septal deviation may lead to breathing difficulties. At approximately 5 to 7 months of age, corrective surgery can be performed.

67
Q

Triadan numbering system

A

The “rule of 4 and 9” helps when using the . The canines will always be 04 and the first molar is 09.

68
Q

Stomatitis

A

Characterized by severe inflammation of the gingiva and the mucosa. Most common in cats

69
Q

Describe cat/dog dentation

A

Brachydont teeth
Characterized by small distinct crowns, well- developed roots, singular apices, and no continuous growth or eruption

70
Q

How quickly can dental plaque mineralize?

A

24 hrs

71
Q

The periodontium includes:

A

The gingiva, alveolar bone, periodontal ligament, and cementum.

72
Q

Scalers are used on______, while curettes are used _______

A

The tooth crown,
below the gingival margin.

73
Q

Disease in the inner chamber of horses’ teeth is

A

most commonly a root abscess.

74
Q

Which nerve block isn’t needed in cats or brachiocephalic dogs

A

Maxillary nerve block
Instead the infraorbital block affects the entire maxilla on the corresponding side due to the short infraorbital foramen in these animals.
