In Vladimír Jekl et al. Use of micro-CT imaging to assess ventral mandibular cortical thickness and volume in an experimental rodent model with chronic high phosphorus intake:
What location was chosen to measure the bone thickness in male degus?
note: full article not yet published. Abstract only as of 11-13-21
The micro-CT scanning, and wall thickness analysis was applied on region of the mandible exactly under the apices of the 4th premolar tooth, first and second molar tooth
In Vladimír Jekl et al. Use of micro-CT imaging to assess ventral mandibular cortical thickness and volume in an experimental rodent model with chronic high phosphorus intake:
Was mandibular bone thickness significantly thinner in the group fed a high phosphorus diet?
note: full article not yet published. Abstract only as of 11-13-21
Yes. Mandibular bone volume and thickness located apically to the premolar and molars were statistically significantly smaller/thinner in group fed by high phosphorus diet. The thinnest bone measured 0.004 mm, where the 4th premolar tooth almost perforated mandibular cortex.
Why are degus ideal for studies looking at the influence of different environmental, infectious, or metabolic factors on the growing tooth, alveolar bone formation, and bone pathologies?
Degus have continuously growing dentition, and the effect of any of the above listed factors can be studied in this animal model at any age and for longer time periods.
In Kendall Taney, Mark M. Smith, et. all. Risk Factors for Failure of Hard Palate Mucoperiosteal Flap Repair of Acquired Oronasal Communication in Dogs: A Pilot Study:
What percentage of cases resulted in failure (had a persistent oronasal fistula)?
25% (7/28 cases)
In Kendall Taney, Mark M. Smith, et. all. Risk Factors for Failure of Hard Palate Mucoperiosteal Flap Repair of Acquired Oronasal Communication in Dogs: A Pilot Study:
Which of the following risk factors were found to significantly increase risk of failure of flap repair?
- increasing age,
- sex,
- increase in body weight,
- presence of neoplasia at the time of surgery
- presence of neoplasia after surgery (incomplete margins),
- the use of CO2 laser
- previous surgeries in the same location,
- HPF blood supply
- the size of the HPF (as a percentage of the total area of the hard palate mucoperiosteum)
- distance traveled by the apex of the HPF
Within this sample, the presence of neoplasia at the time of initial surgery, increasing the area of the HPF, and distance traveled by the HPF apex were associated with a greater odds of HPF failure.
Patients with presence of neoplasia prior to surgery had a 4.5-fold odds of HPF failure compared to those without
BOTH Larger FLAP AREA and HIGHER APEX TRAVEL DISTANCE were SIGNIFICANTLY larger in cases of failure.
NO SIGNIFICANT DIFFERENCES:
- in AGE or SEX
- in MARGINS post op
- to PREVIOUS PROCEDURES
- BLOOD SUPPLY associated with failure.
- the use of CO2 laser
In Kendall Taney, Mark M. Smith, et. all. Risk Factors for Failure of Hard Palate Mucoperiosteal Flap Repair of Acquired Oronasal Communication in Dogs: A Pilot Study:
Did bigger body weights increase or decrease the odds of failure?
Decreases (larger dogs have lower risk of failure):
For every kilogram increase in body weight, the odds of HPF failure decreased by 6%
In Kendall Taney, Mark M. Smith, et. all. Risk Factors for Failure of Hard Palate Mucoperiosteal Flap Repair of Acquired Oronasal Communication in Dogs: A Pilot Study:
Did neoplasia prior to ONF surgery increase or decrease the odds of failed surgery?
INCREASED
Patients with presence of neoplasia prior to surgery had a 4.5-fold odds of HPF failure compared to those without
In Frontiers The Frequency of Communication Between the Synovial Compartments of the Equine Temporomandibular Joint: A Contrast-Enhanced Computed Tomographic Assessment
Of the 20 horses, was communication found between the two synovial compartments of the equine TMJ?
No - there was no PHYSIOLOGICAL communciation between the DTJ and the DMJ in the horses studied. Two horses had PERFORATION of the intra-articular disc in the region of the caudomedial fibrous expansion
In Soukup et, al Incidence and Risk Factors for Surgical Site Infections Following Oromaxillofacial Oncologic Surgery in Dogs:
What percent of the 226 dogs included in this retrospective study developed surgical infection at the site of surgery?
7.5%
In Soukup et, al Incidence and Risk Factors for Surgical Site Infections Following Oromaxillofacial Oncologic Surgery in Dogs:
What was significantly assoociated with the development of infection?
Anesthetic events lasting more than 6 hours.
Signalment, comorbidities, administration of anti-inflammatory and immunosuppressive medications, tumor type, histological margin evaluation, surgical procedure location, and antibiotic protocols were not significant contributors to development of infection
In Soukup et, al Incidence and Risk Factors for Surgical Site Infections Following Oromaxillofacial Oncologic Surgery in Dogs:
Was the use of antibiotics in this cohert protective against the development of infection?
No
True or false:
A surgical site infection is defined by the Centers for Disease Control and Prevention (CDC) as a post-surgical infection that occurs _within 30 day_s of the surgical procedure (or within 1 year of an implant placement) and must include at least one of the following features: purulent debris; positive bacterial culture; or pain, swelling, heat, and redness at the surgical site
TRUE
The American Veterinary Dental College (AVDC) position statement recommends systemically administered antibiotics to reduce bacteremia in what subset of animals?
Animals with underlying systemic disease, such as sub-aortic stenosis or severe renal disease, and in the face of a severe oral infection.
The position statement addresses systemic antibiotic use but does not differentiate between prophylactic and therapeutic treatment.
In Soukup et, al Incidence and Risk Factors for Surgical Site Infections Following Oromaxillofacial Oncologic Surgery in Dogs:
The study found that 7.5% of the animals in this study developed infection. Specifically, what was the percentage of infection in animals who’s surgery was longer than 6 hour?
19.4%
Of the dogs in Soukup et, al Incidence and Risk Factors for Surgical Site Infections Following Oromaxillofacial Oncologic Surgery in Dogs
although not significantly significant (but close) – were dogs more or less likely to develop infection if their surgery was done in the dental suite and not the surgical suite.
Dogs were LESS likely to develop infection if the surgery was performed in the DENTAL suite and MORE likely to develop infection if the surgery was in the SURGICAL suite.
