Treatment of Oral Disease in Eight Pet Pot-Bellied Pigs (Sus scrofa domesticus): A Case Series.

Abstract

Evidence of porcine oral pathology in client-owned domestic pigs has been reported in recent literature. The most common abnormalities are missing teeth and periodontal disease. This case series reviews the diagnosis and treatment of dental disease in 8 pet Vietnamese Pot-Bellied Pigs (Sus scrofa domesticus) over a 6-year period (2015-2021). Inclusion criteria included pigs over 1 year of age that had at least 2 sequential visits involving photographs, full-mouth intraoral radiographs, and dental charting. Eight pigs were identified for study inclusion. The study population included 4 castrated males, 3 spayed females, and 1 intact female. The 8 subjects had a total of 28 visits. Fifty-five intraoral dental extractions were performed and complete healing of 44 extraction sites was observed (11 sites were lost to follow up). Canine tooth reduction was performed on 52 tusks in 7 pigs with exposure of 1 pulp that was treated by partial pulpectomy and direct pulp capping. Restoration of carious lesions was performed on 4 teeth. The most commonly extracted teeth were the right and left maxillary first molars (10 of 47 teeth). Reasons for tooth extraction included: periodontal disease, complicated crown fracture, nonvital +/- periapical pathology, and persistent deciduous teeth. Additional treatments ranged from type 1 crown lengthening with restoration of carious lesions, tusk trimming, closed and open root planing, dental extractions, ultrasonic scaling, and polishing. This article stresses the importance of routine dental healthcare and early intervention for periodontal disease in pigs.
