Q

According to Miguel Carreira L, Daniela D, Pedro A. in

Serum Ionized Calcium Quantification for Staging Canine Periodontal Disease: A Preliminary Study

What was found with regards to serum iCa and PdDz.

how does it compare to the other study by the same authors?

A

ionized calcium goes up with worsening PdDz.

exactly opposite to other study by the same authors, which says it goes down as animals age and as PDDz gets worse.

Q

According to Losinski SL, Stanley BJ, Schallberger SP, Nelson LL, Millard HAMT. in

Versatility of the Angularis Oris Axial Pattern Flap for Facial Reconstruction,

What are the landmarks for the flap incisions?

A

dorsal border of the flap: incision along the ventral aspect of the zygomatic arch, extending caudally to either just beyond the vertical ear canal or to the wing of the atlas, depending on the desired length of the flap

The ventral border of the flap was created with a parallel incision at the level of the horizontal ramus of the mandible, and the caudal border of the flap was created by joining these ventral and dorsal incisions.

Q

Accoding to Snyder CJ, Soukup JW, Drees R, Tabone TJ. in

Caudal Mandibular Bone Height and Buccal Cortical Bone Thickness Measured by Computed Tomography in Healthy Dogs,

Why were they looking for 2mm of thickness?

A

need 2mm of thickness of cortical bone to generate compression with plate fixation and monocortical screws

Caudal Mandibular Bone Height and Buccal Cortical Bone Thickness Measured by Computed Tomography in Healthy Dogs,

what thickness was found in all medium and large dogs at 3mm from the alveolar margin?

Q

Accoding to Snyder CJ, Soukup JW, Drees R, Tabone TJ. in

Caudal Mandibular Bone Height and Buccal Cortical Bone Thickness Measured by Computed Tomography in Healthy Dogs,

What was found in the distal root of M1 location?

A

fewer measurements,

since they start at the alveolar crest and measure thickness every 3 mm moving down the mandible,

indicates loss of mandibular height at this location

Q

Accoding to Snyder CJ, Soukup JW, Drees R, Tabone TJ. in

Caudal Mandibular Bone Height and Buccal Cortical Bone Thickness Measured by Computed Tomography in Healthy Dogs,

what was the recommendation about anchorage over roots of PM4 and M1?

A

Bone is thinner in this location and so anchorage here should be avoided

17
Q

Accoding to Snyder CJ, Soukup JW, Drees R, Tabone TJ. in

Caudal Mandibular Bone Height and Buccal Cortical Bone Thickness Measured by Computed Tomography in Healthy Dogs,

At what level is it recommended to place anchorage?

A

6-9 mm below the alveolar margin

18
Q

Accoding to Snyder CJ, Soukup JW, Drees R, Tabone TJ. in

Caudal Mandibular Bone Height and Buccal Cortical Bone Thickness Measured by Computed Tomography in Healthy Dogs,

How many screws are recommended?

does the number of screws or mono versus bicortical screws make a bigger difference in a 2mm adaption plate?

A

3 screws on either side

number of screws makes a bigger difference than having bicortical anchorage

19
Q

According to Soltero-Rivera M, Engiles JB, Reiter AM, Reetz J, Lewis JR, Sánchez MD. in

Benign and Malignant Proliferative Fibro-osseous and Osseous Lesions of the Oral Cavity of Dogs,

what are the histological findings with ossifying fibroma and fibrous dysplasia?

A

replacement of bone with fibrous tissue with various degrees of ossification and mineralization;

bland spindle shaped cells surrounding woven bone trabeculae with no evidence of malignancy

20
Q

According to Soltero-Rivera M, Engiles JB, Reiter AM, Reetz J, Lewis JR, Sánchez MD. in

Benign and Malignant Proliferative Fibro-osseous and Osseous Lesions of the Oral Cavity of Dogs,

What are the radiographic differences between ossifying fibroma and fibrous dysplasia?

A
  • OF – ossifying fibroma
    • appears well-circumscribed with sharply defined borders
  • FD fibrous dysplasia
    • characterized by poorly discernible borders that blend in with the surrounding bone (ill-defined margins)
21
Q

According to Soltero-Rivera M, Engiles JB, Reiter AM, Reetz J, Lewis JR, Sánchez MD. in

Benign and Malignant Proliferative Fibro-osseous and Osseous Lesions of the Oral Cavity of Dogs,

What is the malignant lesion that can mimic these lesions?

what are it’s histo and rad characteristics?

A

low grade osteosarcoma

Bone invasion and subtle cytologic atypia on histo

imaging may be suggestive of a more aggressive lesion

22

According to Soltero-Rivera M, Engiles JB, Reiter AM, Reetz J, Lewis JR, Sánchez MD. in

Benign and Malignant Proliferative Fibro-osseous and Osseous Lesions of the Oral Cavity of Dogs,

Where do osteomas arise and what differentiates them?

A

arise on the surface of bones that ossify by intramembranous route

histologically distinct, and well circumscribed on rads
