Ophthalmic manifestations and complications of dental disease in dogs and cats

Because of the intimate anatomic relationship between the maxillary dentition and ophthalmic structures, dental disease may manifest itself as ophthalmic disease. Primary dental disease should always be a consideration when encountering diseases involving the globe and/or orbit. Dental radiographs can help identify any existing dental disease. Inappropriate dental treatment may also result in iatrogenic damage to ophthalmic structures.

Effect of Bupivacaine on Postoperative Pain for Inferior Alveolar Nerve Block Anesthesia after Single-visit Root Canal Treatment in Teeth with Irreversible Pulpitis

Parirokh M, Yosefi MH, Nakhaee N, et al: J Endod 2012; 38(8): 1035-1039. 

Control of pain after root canal treatment is an important aspect of both human and veterinary dentistry.  This study compared the use of bupivicaine with epinephrine with lidocaine with epinephrine in the control of pain after human patients received root canal treatment of the mandibular first or second molar teeth.  The results demonstrated that the patients that received bupivicaine had lower pain scores and used less analgesics than the patients that received lidocaine for their nerve block.  It is a logical step of reasoning that our veterinary patients will benefit from the use of bupivicaine not only for endodontic treatments but likely for other dental procedures as well.

Clinical signs and histologic findings in dogs with odontogenic cysts
Verstraete FJ, Zin BP, et al: J Am Vet Med Assoc. 201, 1;239(11):1470-6.

Odontogenic cysts develop from odontogenic epithelium and can be either the result of inflammation or are developmental in origin. The cysts contain either fluid or semi-solid material. Dentigerous cysts are associated with an unerupted tooth. The cystic expansion of dentigerous cysts can be extensive, and may result in significant bony destruction. In this study, of the 41 dogs that were evaluated, 29 dogs (71%) had dentigerous cysts. 83% of these cysts were associated with an unerupted mandibular 1st premolar tooth. This study underscores the importance of conducting a thorough oral exam at an early age, especially at the time of spaying or neutering. If a tooth is missing, dental radiography can be performed to determine if the tooth is present and unerupted. Extraction of the tooth can prevent dentigerous cyst formation.

Relevance of feline calicivirus, feline immunodeficiency virus, feline leukemia virus, feline herpes virus, and Bartonella henselae in cats with chronic gingivostomatitis
Belgard S, Truyen U, Thibault JC, et al. Berl Munch Tierarztl Wochenschr. 2010, 123 (9-10):369-376.

This study showed a statistically significant prevalence of feline calicivirus RNA in cats with stomatitis (53.8%) compared to the control group (14%). It also showed a significant difference in the prevalence of antibodies to feline calicivirus in cats with stomatitis (78.8%) compared to the control group (58%). No other infectious agents tested had a significant correlation. The results differ from a study by Quimby JM et al. (Evaluation of the association of Bartonella species, feline herpesvirus 1, feline calicivirus, feline leukemia virus and feline immunodeficiency virus with chronic feline gingivostomatitis. In J Feline Med Surg 2008 Feb; 10(1):66-72) which did not show any correlations with gingivostomatitis and the tested infectious agents including feline calicivirus. More research is needed for this disease.
