Abstrakt: Dogs use their teeth for a multitude of tasks and, as such, it is vital for their health and wellbeing that their oral health is maintained. Persistent deciduous teeth (PDT), those that fail to fall out at the appropriate time, are associated with malocclusion (misaligned bite), soft tissue trauma and increased risk of periodontal disease. The objective of the current study was to perform a retrospective analysis of veterinary medical data to understand the effect of dog breed size, dog breed and body weight on prevalence of PDT. Medical records collected from almost 3 million dogs visiting a chain of veterinary hospitals across the United States over a 5-year period showed an overall prevalence of 7% for PDT, the data represented 60 breeds with extra-small breeds (<6.5 kg) showing significantly higher prevalence (15%) than all other breed sizes (P < 0.001). Statistical modelling of extra-small, small and medium-small breed sizes showed that those on Wellness Plans or that had not received a dental prophylaxis for at least two years had significantly increased odds of PDT being detected (Odds ratio 2.72-3.2 and 2.17-3.36 respectively, P < 0.0001). Dogs with a below ideal body condition score had a decreased odds of PDT (Odds ratio 0.57-0.89, P < 0.0001) whereas those above ideal had an increased odds (Odds ratio 1.11-1.60, P < 0.0001). The findings from this extensive dataset highlight the importance of regular veterinarian examinations to identify and remove PDT, helping to avoid increasing the risk of associated issues such as periodontal disease and malocclusion.
