PMID 42278063 — Canine Periodontal Disease in an Urban Clinical Setting and Its Relationship with Host Factors and the Subgingival Bacterial Profile in Ecuador. (Animals : an open access journal from MDPI, 2026). Abstract (opening): Canine periodontal disease is a highly prevalent chronic inflammatory condition with a multifactorial etiology, influenced by host factors and complex subgingival bacterial *[CC BY — Open Access, verbatim with attribution.]*\n2. PMID 41922436 — Ecological network collapse and functional potential shifts in the canine oral microbiota associated with periodontal disease: a pilot study. (Scientific reports, 2026). Abstract (opening): Periodontal disease is a highly prevalent disease in dogs; however, the underlying shifts in the oral microbiota remain unclear. Although dysbiosis is often associated with a loss *[CC BY — Open Access, verbatim with attribution.]*\n3. PMID 41712493 — *[Paraphrased derived summary — non-Open-Access source.]* A 2026 Journal of Veterinary Dentistry overview states periodontal disease is the most prevalent oral condition in companion animals, affecting over 80% of dogs and cats by age three, despite its high incidence and systemic implications; the excerpt is cut off before the dietary/management discussion.\n4. PMID 41872912 — A pilot study on the novel use of an ultrasonic toothbrush in dogs: limited effect on dental calculus following a single treatment. (Acta veterinaria Scandinavica, 2026). Abstract (opening): Background Dental calculus is common in dogs and contributes to periodontal disease by promoting plaque accumulation. While daily tooth brushing is the gold standard for *[CC BY — Open Access, verbatim with attribution.]*\n5. PMID 42328069 — Canine Tooth Microbiome Gingival Index: a new microbiome-derived measure of gingival health validated by nutritional intervention. (Frontiers in veterinary science, 2026). Abstract (opening): Introduction Periodontitis affects over 80% of dogs over 3 years of age, progressing irreversibly from gingivitis due to an imbalance in the subgingival microbial community that *[CC BY — Open Access, verbatim with attribution.]*\n6. PMID 42188950 — Breed-Specific Dental Variations in Dogs Assessing Malocclusions Using Computed Tomography (CT). (Veterinary sciences, 2026). Abstract (opening): Dental malocclusions are common and often underdiagnosed situations in dogs, which might result in oral trauma, impaired mastication, and periodontal disease.
