Diagnostic yield of dental radiography and digital tomosynthesis for the identification of anatomic structures in dogs.

Introduction: The purpose of this study was to evaluate the use of a novel imaging modality, digital tomosynthesis (DT), for identification of predefined anatomic dental and maxillomandibular structures in dogs.

Methods: DT images were compared to conventional intraoral dental radiography (DR) for the diagnostic yield regarding the presence and quality of visualization of 35 structures. DT imaging and full mouth DR were obtained on 16 canine cadaver heads and a semi-quantitative scoring system was used to characterize the ability of each imaging method to identify the anatomic structures.

Diagnostic yield of dental radiography and digital tomosynthesis for the identification of anatomic structures in cats.

Introduction: Digital tomosynthesis (DT) has emerged as a potential imaging modality for evaluating anatomic structures in veterinary medicine. This study aims to validate the diagnostic yield of DT in identifying predefined anatomic structures in feline cadaver heads, comparing it with conventional intraoral dental radiography (DR).

Methods: A total of 16 feline cadaver heads were utilized to evaluate 19 predefined clinically relevant anatomic structures using both DR and DT.

Surgical management of maxillary and premaxillary osteomyelitis in a reticulated python (Python reticulatus).

CASE DESCRIPTION A 1-year-old reticulated python (Python reticulatus) was evaluated because of a 2-week history of wheezing and hissing. CLINICAL FINDINGS Rostral facial cellulitis and deep gingival pockets associated with missing rostral maxillary teeth were evident. Tissues of the nares were swollen, resulting in an audible wheeze during respiration.

Benign cementoblastoma (true cementoma) in a cat.

Case Summary: A 10-year-old castrated male domestic shorthair cat was presented for assessment of a gingival mass surrounding the left maxillary third and fourth premolar teeth. The mass was surgically removed by means of a marginal rim excision, and the tissue was submitted for histological assessment. It was identified as a benign cementoblastoma (true cementoma).

Effect of tooth extraction on stomatitis in cats: 95 cases (2000-2013).

Objective: To evaluate long-term response of cats with stomatitis to tooth extraction.

Design: Retrospective case series.

Animals: 95 cats with stomatitis.

Applied feline oral anatomy and tooth extraction techniques: an illustrated guide.

Practical Relevance: Tooth extraction is one of the most commonly performed surgical procedures in small animal practice.

Clinical Challenges: The clinician must be familiar with normal oral anatomy, utilize nomenclature accepted in dentistry and oral surgery, use the modified Triadan system for numbering teeth, identify normal structures on a dental radiograph, understand the tissues that hold the teeth in the jaws, know the biomechanical principles of tooth extraction, be able to choose the most appropriate instrument for removal of a tooth, extract teeth using closed and open techniques, and create tension-free flaps for closure of extraction sites.

Audience: This review is intended to familiarize both the general and referral practitioner with feline oral anatomy and tooth extraction techniques.

Prevalence of regional and distant metastasis in cats with advanced oral squamous cell carcinoma: 49 cases (2005-2011).

The objective of this study was to evaluate the prevalence of regional and distant metastasis in cats with advanced oral squamous cell carcinoma (SCC) in a retrospective case series. Forty-nine cats with cytologically- or histopathologically-confirmed oral SCC presented to the Matthew J Ryan Veterinary Hospital of the University of Pennsylvania. History, clinical and laboratory results, diagnostic imaging findings and survival times were obtained from the medical records of patients who received diagnostic evaluation for metastasis.
