Tooth Elongation of Maxillary Second Premolars and Mandibular Third Molars and Associated Periodontal Disease in Horses: A Retrospective Study.

Periodontal disease has been identified in horses and donkeys through the millennia at a prevalence of up to 75% and is a leading cause of tooth loss in horses. We hypothesize that there is a correlation between tooth elongations and periodontal disease. Dental records of all client owned horses examined by a single AVDC/equine board certified practitioner in 2016-2018 were analyzed. Inclusion criteria consisted of the examination finding of tooth elongation of one of the following teeth pairs 106/107, 206/207, 310/311, or 410-411. The included cases were then examined for the finding of periodontal disease in Stages 1-4 (PD 1-4). Bayesian correlation analysis revealed significant positive correlations of elongations and periodontal disease existed between PD1 and proximal tooth pairs 106-107 and 206-207, PD2 and PD4 with all four tooth pairs, and PD3 with 106-107. Clinically, early diagnosis and treatment of newly formed elongations, or prevention of their formation altogether through diligent dental prophylaxis could prove key in preservation of teeth through prevention of the associated development of periodontal disease in the horse.

Using the Digital Platform ExamSoft in Veterinary Anatomy and Parasitology Assessments in Written and Laboratory Components.

The Ohio State University College of Veterinary Medicine (CVM), with a class size of 162, is one of the largest in the nation. In an effort to streamline examination procedures, create a consistent assessment format among courses, replace paper exams, track test questions linked to learning objectives, and reduce exam grading time, our DVM program adopted the use of ExamSoft for core courses beginning in the autumn semester 2014. ExamSoft is an electronic assessment application, which provides a secure testing environment and robust reporting features. CVM uses it for high stakes midterm and finals. Although easily adopted into a didactic course format, its application in laboratory-based examinations proved challenging. Designing, setting up and grading exams for Anatomy and Parasitology courses with a laboratory component have always required substantial time investment, and adding a testing application to the process demanded rethinking and restructuring logistics. After two semesters of process refinement and standardization of a testing device to the iPad, faculty teaching in the Anatomy and Parasitology courses were able to implement ExamSoft in a laboratory setting to realize the same assessment and efficiency gains. Here we describe the benefits of ExamSoft testing in the written and laboratory settings and the lessons learned during the 2-year transition.
