Question 1

In Dixon’s 2014 study “Critical evaluation of ex vivo restoration of carious equine maxillary cheek teeth infundibulae following high-pressure gas and micro-particle abrasion”, at what depth was there a correlation with incomplete restoration of an infundibula?

TVJ 2014

Answer 1

15mm

Question 2

In Dixon’s 2014 study “Critical evaluation of ex vivo restoration of carious equine maxillary cheek teeth infundibulae following high-pressure gas and micro-particle abrasion”, what % of deep infubibulae were incompletely restored?

TVJ 2014

Answer 2

54%

This study has demonstrated that high-pressure abrasion with aluminium hydroxide particles is ineffective at removing food debris and carious dental material from carious infundibulae >15 mm in depth

Question 3

In Suske’s paper “Infundibula of equine maxillary cheek teeth Part 2: Morphological variations and pathological changes”, how prevalent was cemental hypoplasia at the occlusal and subocclusal level on CT respectively?

TVJ 2016

Answer 3

Cemental hypoplasia was present in at least one infundibulum in CT of 351/688 (51%) cases at the occlusal surface and in CT of 100/177 (56%) cases at a subocclusal level

Question 4

In Suske’s paper “Infundibula of equine maxillary cheek teeth Part 2: Morphological variations and pathological changes”, what was the most commonly affected tooth by cemental hypoplasia (triadan position)

TVJ 2016

Answer 4

09s (75% of affected teeth)

Question 5

In Borkent’s 2016 study “An epidemiological survey on the prevalence of equine peripheral dental caries in the United Kingdom and possible risk factors for its development”, what was the prevalence of PCs in this UK population of horses?

EVJ 2016

Answer 5

51.7%

In contast to Ramzan 2011 on referral cases – 61%
In contrast to other post-mortem studys (3-6%)

Question 6

In Borkent’s 2016 study “An epidemiological survey on the prevalence of equine peripheral dental caries in the United Kingdom and possible risk factors for its development”, what Triadan positions were more likely affected? Was maxilla or mandible more likely affected?

EVJ 2016

Answer 6

09s-11s
Mand > Maxilla

Peripheral caries preferentially affects the
caudal upper and lower cheek teeth indicating an environmental change in the caudal oral cavity that favours the growth of cariogenic bacteria

Question 7

In Borkent’s 2016 study “An epidemiological survey on the prevalence of equine peripheral dental caries in the United Kingdom and possible risk factors for its development”, what concurrent dental disorder increased the chances of PC presence the most?

EVJ 2016

Answer 7

Presence of infundibular caries
