Dental wax decreases calculus accumulation in small dogs.

A dental wax was evaluated after unilateral application in 20 client-owned, mixed and purebred small dogs using a clean, split-mouth study model. All dogs had clinical signs of periodontal disease including plaque, calculus, and/or gingivitis. The wax was randomly applied to the teeth of one side of the mouth daily for 30-days while the contralateral side received no treatment. Owner parameters evaluated included compliance and a subjective assessment of ease of wax application. Gingivitis, plaque and calculus accumulation were scored at the end of the study period. Owners considered the wax easy to apply in all dogs. Compliance with no missed application days was achieved in 8 dogs. The number of missed application days had no effect on wax efficacy. There was no significant difference in gingivitis or plaque accumulation scores when comparing treated and untreated sides. Calculus accumulation scores were significantly less (22.1 %) for teeth receiving the dental wax.

Oral health benefits of a daily dental chew in dogs.

An independent study was conducted to determine and quantify the oral care benefits of a daily edible dental chew in dogs as measured by plaque and calculus control, gingival indices, and oral malodor. A "clean mouth" test model was used comparing a commercial dry diet and a commercial dry diet plus one dental chew per day. The dental chew tested was representative of a retail canine dental chew. The test dental chew was a green-colored dental dog chew with a flexible texture that can be readily chewed by dogs. They are made with a knuckle bone shape on one end and a toothbrush shape on the other end. Sixty adult dogs were allocated in either control or test groups based on plaque stratification and studied for 28-days. The test group (30 dogs) received a dry diet and 1 dental chew each day. The control group (30 dogs) received the same dry diet only. At the end of the study, measurements of plaque and calculus accumulation and evaluations of oral malodor and gingival heath were performed. Adding a dental chew to the diet resulted in statistically significant reductions in plaque and calculus accumulation, and oral malodor while improving gingival indices.

Canine periodontal disease control using a clindamycin hydrochloride gel.

Stabilizing or reducing periodontal pocket depth can have a positive influence on the retention of teeth in dogs. A topical 2% clindamycin hydrochloride gel (CHgel) was evaluated for the treatment of periodontal disease in dogs. The CHgel formulation provides for the sustained erosion of the matrix, but also flows into the periodontal pocket as a viscous liquid, and then rapidly forms a gel that has mucoadhesive properties and also may function as a physical barrier to the introduction of bacteria. A professional teeth cleaning procedure including scaling and root planing was done in dogs with one group receiving CHgel following treatment. Periodontal health was determined before and after the procedure including measurement of periodontal pocket depth, gingival index, gingival bleeding sites, and number of suppurating sites. There was a statistically significant decrease in periodontal pocket depth (19%), gingival index (16%), and the number of bleeding sites (64%) at 90-days in dogs receiving CHgel. Additionally, the number of suppurating sites was lower (93%) at 90-days for the group receiving CHgel. The addition of CHgel effectively controlled the bacterial burden (e.g, Fusobacterium nucleatum) at both day 14 and 90. Gingival cells in culture were shown to rapidly incorporate clindamycin and attain saturation in approximately 20-minutes. In summary, a professional teeth cleaning procedure including root planning and the addition of CHgel improves the gingival index and reduces periodontal pocket depth.

Effectiveness of a vegetable dental chew on periodontal disease parameters in toy breed dogs.

Sixteen toy breed dogs completed a parallel, 70-day two-period, cross-over design clinical study to determine the effect of a vegetable dental chew on gingivitis, halitosis, plaque, and calculus accumulations. The dogs were randomly assigned into two groups. During one study period the dogs were fed a non-dental dry diet only and during the second study period were fed the same dry diet supplemented by the daily addition of a vegetable dental chew. Daily administration of the dental chew was shown to reduce halitosis, as well as, significantly reduce gingivitis, plaque and calculus accumulation and therefore may play a significant role in the improvement of canine oral health over the long-term.

Post-anesthesia deafness in dogs and cats following dental and ear cleaning procedures.

OBJECTIVE: The present study was performed to document hearing loss in dogs and cats following procedures performed under anesthesia. Most cases of reported hearing loss were subsequent to dental and ear cleaning procedures. STUDY DESIGN: Prospective and retrospective case survey. ANIMALS: Subjects were dogs and cats with deafness, personally communicated to one author, cases discussed on a veterinary information web site, and cases communicated through a survey of general practice and dental specialist veterinarians. METHODS: Reported deafness cases were characterized by species (dog, cat), breed, gender, age, and dog breed size. RESULTS: Sixty-two cases of hearing loss following anesthesia were reported between the years 2002 and 2009. Five additional cases were reported by survey respondents. Forty-three cases occurred following dental procedures. Sixteen cases occurred following ear cleaning. No relationship was observed between deafness and dog or cat breed, gender, anesthetic drug used, or dog size. Geriatric animals appeared more susceptible to post-anesthetic, post-procedural hearing loss. CONCLUSIONS: Deafness may occur in dogs and cats following anesthesia for dental and ear cleaning procedures, but the prevalence is low. The hearing loss appears to be permanent. CLINICAL RELEVANCE: Deafness can be a consequence following anesthesia for dental or ear cleaning procedures. Older animals may have greater susceptibility.

Development and Evaluation of a Novel Oral Mucoadhesive Ointment Containing Pomegranate Peel Extract as an Adjuvant for Oral Hygiene of Dogs.

Herbal therapies are used worldwide to treat a variety of health conditions, including dental conditions in veterinary medicine. In this context, the use of medicinal plant-based formulations as potential therapeutics and preventatives in veterinary dentistry is worth highlighting. The objective of the present study was to develop a mucoadhesive ointment formulation, named orabase, that contained pomegranate extract for use in the oral cavity of dogs, with the aim of improving their oral hygiene. The hydroalcoholic extracts of pomegranate peels was incorporated into the orabase in 3 different concentrations. The formulations were subjected to in vitro microbiological testing by a modified disc-diffusion method to study the susceptibility of microorganisms collected from the oral cavities of the dogs. The samples were taken from the buccal mucosa of dogs having the same management and diet. The most effective formulation was submitted to physicochemical tests to evaluate the functionality of the product, namely pH, swelling index, spreadability, and mechanical properties (hardness, cohesiveness, and adhesiveness). The formulation containing 25.0% w/w of the extract was considered most suitable for the intended use as it showed antiseptic activity and demonstrated a swelling index of approximately 35% in the first 20 minutes of the test, high spreadability, and suitable mechanical properties. The results suggest that the product obtained from pomegranate peel extract is a viable option for use to improve oral hygiene, helping to reduce the bacterial component of dental plaque in dogs.

Effect of feeding a daily oral care chew on the composition of plaque microbiota in dogs.

The objective of this study was to investigate the influence of daily feeding of an oral care chew on the composition of canine supragingival plaque microbiota. Twelve beagle dogs were recruited to the randomized cross-over study. The dogs were fed one of two dietary regimes, both consisting of a commercially available wet and dry diet mix, either with or without daily supplementation with an oral care chew. After each 28-day test phase, supragingival plaque samples were collected and processed via Illumina sequencing to determine the microbiota composition. A comparative analysis of bacterial species associated with health and periodontal disease, identified from prior clinical studies, revealed differences between the dietary regimes. Consumption of the daily oral care chew, resulted in a significant increase in proportion of 6 health associated taxa but only 3 disease associated taxa compared to no chew. In contrast, 8 disease and 1 health associated taxa showed increased proportions for no chew versus the oral care chew. Daily feeding of the oral care chew tested in this study has therefore been shown to increase the proportion of health associated bacteria, over bacteria associated with periodontal disease, in supragingival plaque compared to no chew. By influencing plaque microbiota towards a bias for health associated bacteria, feeding of the oral care chew provides a means to reduce the prevalence of bacterial species shown to be associated with periodontal disease in dogs.

Application of the gingival contour plaque index: six-month plaque and gingivitis study.

The Gingival Contour Plaque Index (GCPI) is a recently introduced and validated method of measuring plaque accumulation in dogs. It focuses on plaque accumulated along the gingival margin. Plaque accumulation in this area leads to gingival inflammation and, potentially, periodontitis. A 6-month plaque and gingivitis study was conducted to demonstrate the clinical research application of the GCPI, and to ensure that documented quantification of plaque-reducing efficacy could be related to a reduction in gingivitis. Advantages of the GCPI method are the ability to quantify plaque accumulation in an awake dog with fewer research personnel and more efficient time usage.

Development of dental hygiene gum for cats considering their anatomical features of dentition.

The purpose of this study was to develop effective dental hygiene chews for cats based on the anatomical features of the dentition and patterns of chewing motion. All cats were volunteered for dental prophylaxis followed by dental impressions using yellow stone and alginate under general anesthesia. Twenty parameters related to dentition were defined in order to compare dental impressions using digital caliper. For the chewing motion study, patterns of chewing motion were identified based on recordings made with a digital camera. Ten cats (4 domestic shorthairs, 2 Russian blues, 1 American shorthair, 1 Persian, 1 Turkish Angora, and 1 Devon Rex) were recruited for the study. The parameters related to teeth and oral size were similar among the studied cats. Chewing motion can be described as more of a guillotine-like motion rather than a crushing motion, with cats chewing 3-7 times before swallowing. The chewing pattern of cats involves shearing for a short period of time followed by immediate swallowing. Therefore, the overall size of the dental hygiene chew could be determined based on the measurement of the oral size for inducing chewing. The surface details of the dental hygiene chew could be designed for prevention and removal of dental calculus and plaque in cats considering the anatomical teeth parameters. Dental hygiene chews customized for cats considering the different anatomical features of their teeth might be effective for oral care.

Computer simulations of food oral processing to engineer teeth cleaning.

Oral biofilm accumulation in pets is a growing concern. It is desirable to address this problem via non-invasive teeth cleaning techniques, such as through friction between teeth and food during chewing. Therefore, pet food design tools are needed towards optimising cleaning efficacy. Developing such tools is challenging, as several parameters affecting teeth cleaning should be considered: the food's complex mechanical response, the contacting surfaces topology as well as the wide range of masticatory and anatomical characteristics amongst breeds. We show that Finite Element (FE) models can efficiently account for all these parameters, through the simulation of food deformation and fracture during the first bite. This reduces the need for time consuming and costly in-vivo or in-vitro trials. Our in-silico model is validated through in-vitro tests, demonstrating that the initial oral processing stage can be engineered through computers with high fidelity.

Effectiveness of an oral hygiene chew to reduce dental deposits in small breed dogs.

Over a period of 4-months, feeding small breed dogs with a regular dry diet supplemented with a daily oral hygiene chew resulted in a significant reduction in plaque deposition (17.3%) and calculus accumulation (45.8%) compared with dogs fed the dry diet alone. Daily feeding of a specifically designed oral hygiene chew that reduces plaque and calculus accumulation may play a role in the severity of canine periodontal disease.

Telephone enquiries about the cost of cleaning the teeth of cats or dogs cannot be answered without clinical investigation of the animal and oral examination under sedation or anaesthesia. This article describes the procedures used during the professional cleaning of the teeth of companion animals. An itemized list of procedures and their cost means that the era of "shopping around" for teeth cleaning is past.

Management of periodontal disease: understanding the options.

Periodontal disease is the most common disease occurring in domestic dogs and cats, and local severity and the impact on the rest of the body are reasons why all companion animal patients should receive an oral examination every time they are seen. This article provides the background information on how an effective periodontal management program can be tailored for each patient.

Geriatric veterinary dentistry: medical and client relations and challenges.

Quality of life is an important issue for geriatric patients. Allowing periodontal disease, fractured teeth, and neoplasia to remain untreated decreases this quality of life. Age itself should be recognized; however, it should not be a deterrent to successful veterinary dental care.

Evidence-based veterinary dentistry: a systematic review of homecare for prevention of periodontal disease in dogs and cats.

Successful treatment and prevention of periodontal disease in pet animals requires a multidimensional approach to identify and eliminate exacerbating factors, provide scheduled professional examinations and care, and plan and implement a dental homecare program. Over the years, many therapeutic and preventive interventions have been developed or advocated for periodontal disease, but evidence of efficacy or effectiveness is highly variable. Accordingly, the main objective of this systematic review is to identify and critically appraise the evidence supporting various aspects of homecare for prevention of canine and feline periodontal disease.

Effective periodontal disease control using dental hygiene chews.

This study evaluated the effectiveness of a newly developed dental hygiene chew for dogs, with and without a natural antimicrobial additive, compared with a reference diet. Efficacy was determined by measuring the severity of gingivitis and the accumulation of dental plaque and calculus in dogs after 4-weeks of being fed the different dietary regimens. Dogs fed a single daily dental chew had significantly less gingivitis (P = 0. 02), plaque (P = 0. 0004), and calculus (P = 0.0001) compared with dogs in the control group that were fed an identical diet but received no chews. The inclusion of the antimicrobial agent did not improve the efficacy of the product. The dental hygiene chews tested in this study have potential to help reduce the incidence of periodontal disease in dogs.

Management of generalized gingival enlargement in a dog--case report and literature review.

The present report describes treatment of a dog with generalized gingival enlargement and serves as a review of etiology and treatment options for this condition. The combined use of scalpel blade, electrosurgical equipment, and a 12-fluted bur on a high-speed handpiece with water irrigation allowed for accurate excision of excess gingival tissue and contouring of remaining gingiva. Surgery coupled with professional dental cleaning/periodontal therapy can decrease the recurrence of this condition. In addition, home oral hygiene is an important component of the treatment plan. The history of patients with gingival enlargement should be reviewed carefully, including drug history and previous medical conditions, in an attempt to elucidate a specific cause and thus allow for greater long-term success.

[Effectiveness of feeding large kibbles with mechanical cleaning properties in cats with gingivitis]. / Effectiviteit van het voeren van een grote brok met mechanisch reinigende werking bij katten met gingivitis.

Periodontal disease is the most common acquired oral disease in cats. It starts with plaque accumulation and gingivitis. The aim of this study was to evaluate the effectiveness of different types of kibble and teeth brushing after professional dental cleaning. To this end, the ratio of facultative anaerobic and obligate anaerobic bacteria was determined, and the amount of plaque and tartar and the severity of gingivitis were measured. Eighty-eight cats with gingivitis and tartar were randomly divided into four groups and given different treatments after professional dental cleaning. The dental treatments were: group 1, cats were fed on small kibbles with mechanical cleaning qualities; group 2, cats were fed on small kibbles without mechanical cleaning qualities, and owners were instructed to brush the cats' teeth; group 3, cats were fed on large kibbles with mechanical cleaning qualities; and group 4, cats were fed on the same kibbles as group 2, but owners were not asked to brush their cats' teeth. A supragingival plaque sample was taken, and used for bacteriological analysis scores for tartar, plaque, and gingivitis were determined at the initial presentation and at 3 and 6 months after professional dental cleaning. Cats fed on the large kibbles with mechanical cleaning qualities (group 3) had significantly less gingivitis and tartar.

Prevention of periodontal disease.

Periodontal disease is the most common disease affecting adult dogs and cats. It is also a very preventable disease. The insidious nature of the disease and requirement for the pet owner to be actively involved make client and public education absolutely vital. Although clients are commonly aware of their pets' bad breath, they rarely notice gingivitis, fractured teeth, and traumatic malocclusions. The annual National Pet Dental Health Month program has resulted in a tremendous increase in public awareness. Veterinarians must carry this further in their everyday practices, convincing our clients of the need for preventive dental care. It is only through clients' ongoing desire and persistence that a long-term preventive program can be successful. This requires a coordinated effort by the entire hospital staff. When successful, clients' pets will live healthier and longer lives.
