A study to compare the effect of a dental hygiene chew with or without 0.2% chlorhexidine on the development of gingivitis and the accumulation of dental deposits was performed using 11 small dogs. Confirming previous data, the daily addition of a standard chew to a dry diet resulted in significantly less gingivitis and calculus after 3 weeks compared with feeding the dry diet alone. Addition of chlorhexidine to the chew made no difference to the degree of gingivitis or the amount of calculus that accumulated, but did result in significantly less plaque accumulation after 3 weeks. The abrasiveness of the chew, rather than the antibacterial activity of chlorhexidine, is likely to have contributed the most to the maintenance of oral health in dogs with mild gingivitis.  相似文献

A study was undertaken to determine the effect of a new dental hygiene chew on periodontal health in the dog. The textural properties of this chew are different from previously tested dental hygiene products. The accumulation of dental deposits, development of oral malodor, and development of gingivitis were assessed in two groups of dogs; one fed a dry diet only, and the other fed the same dry diet supplemented by the daily addition of the new dental hygiene chew. Daily addition of the chew to the dry diet was effective in reducing plaque and calculus accumulation on the tooth surfaces, and also reduced the severity of gingivitis and oral malodor as compared to feeding the dry diet only.  相似文献

The effect of two commercially available dietary regimens on the development of gingivitis and the accumulation of dental plaque, calculus and stain in the dog were studied. One regimen consisted of feeding an oral hygiene chew and a standard dry diet.
The other was based on a specifically designed oral care dry main meal. The study was conducted using 15 dogs in a two period, parallel cross-over design. Each period consisted of a one week pretest phase followed by a three week test phase. During the test phase, gingivitis and plaque were measured after one week and gingivitis, calculus, stain and plaque were measured after a further two weeks. Comparison of the two regimens showed that there were equal amounts of gingivitis, plaque and calculus by the end of the study. There was significantly more stain and significant loss in bodyweight when the main meal was fed.
The role of dietary modification in the maintenance of periodontal health is discussed.  相似文献

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.  相似文献

The use of special diets or dietary adjuncts, although not eliminating the need for regular professional therapy, may serve to improve gingival health during the interval between professional oral health assessments and intervention. This study was performed to determine the effect of a dental chew on dental hygiene and gingival health in cats. The accumulation of dental substrates and the development of gingivitis were assessed in cats fed either a dry diet only or a dry diet supplemented with dental chews. A two-period, crossover design was used with the test phase lasting 4-weeks. Results indicated that the daily addition of dental chews to a dry diet was effective in reducing plaque and calculus accumulation on tooth surfaces in cats, as well as reducing the severity of gingivitis.  相似文献

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.  相似文献

The objective of the study was to investigate the long-term effects of feeding a dental hygiene chew that has been shown to be effective in promoting periodontal health in dogs in short-term studies. Oral malodor, calculus, and plaque scores were still significantly lower after 21 months in the group that was receiving the dental hygiene chew, although gingivitis scores no longer differed significantly. There were no reports of any adverse reactions during the study. The results of the study support that feeding of the dental hygiene chew six days per week reduces accumulation of dental deposits, helps maintain periodontal health, and increases the time interval between professional periodontal intervention.  相似文献

Tooth brushing is considered a superior technique for reducing plaque accumulation. Chemical agents may be used to reduce plaque accumulation on tooth surfaces since many owners may not be willing or able to brush their dog's teeth. Following a professional teeth cleaning procedure, a dental gel containing chlorhexidine was applied in 11 dogs BID for 7-days, while 11 other dogs received a control dental gel applied in the same manner. Dogs in the treatment group had significantly less plaque accumulation during the trial period compared with dogs in the control group. The dental gel applied in the study reported here decreases plaque accumulation in the short-term and may be beneficial in reducing the severity of gingivitis and associated periodontal disease if provided on a long-term basis.  相似文献

A study was undertaken to determine the clinical efficacy of a chew designed to improve dental hygiene in the cat. The accumulation of dental deposits (plaque and calculus) and the effect on gingival inflammation were assessed in 15 client-owned cats while on two different regimens. In the first leg of the study, the cats were fed a nutritionally complete dry diet supplemented with one dental hygiene chew. In the second leg of the study, the same cats were fed only the nutritionally complete diet. This study demonstrated that the daily addition of the chew to the dry diet resulted in significantly less plaque and calculus accumulation on tooth surfaces. It was our experience that daily feeding of the chew helped maintain dental hygiene in cats; however, regular professional therapy is still indicated.  相似文献

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.  相似文献

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.  相似文献

A study was conducted in 40 healthy, randomly selected, client-owned, mixed and purebred dogs to assess the efficacy of a barrier dental sealant. All dogs showed evidence of dental plaque, calculus, or gingivitis. The dental sealant was applied to one side of the mouth following a professional teeth cleaning procedure and reapplied weekly for 8-weeks following the cleaning procedure. Dental parameters evaluated included plaque, calculus, gingivitis, and gingival bleeding indices. A statistically significant difference was detected between treated and untreated teeth compared with baseline values for plaque and calculus at weeks 4 and 8, gingivitis at week 4, and gingival bleeding time at week 8. A professional teeth cleaning procedure followed by a single application of the barrier dental sealant and weekly reapplication performed by a veterinarian or veterinary technician provided significant improvement in plaque and calculus indices during an 8-week period.  相似文献

Twenty-four dogs admitted for routine teeth cleaning were selected arbitrarily to undergo a periodontal examination and a dental radiographic examination before the dental procedure. Data pertaining to the physical and radiographic manifestations of periodontal disease of 783 teeth were collected. All dogs had lesions consistent with periodontal disease, ranging from mild gingivitis and minimal plaque accumulation to severely inflamed gingiva, exuberant calculus formation, and root exposure. Of the 783 teeth examined, 153 (20%) had a pocket depth greater than or equal to 4 mm and less than or equal to 9 mm. Data regarding these teeth were subjected to statistical analysis. The clinical signs of plaque, calculus, mobility, pocket depth, and furcation were positively associated with radiographic signs of periodonta disease. The association between grossly evident gingivitis and radiographic signs of periodontal disease was not significant. Conditional probability analysis was applied to determine confidence intervals for the probability of a radiographic sign of periodontal disease occurring given that a clinical sign of periodontal disease occurs.  相似文献

Ageing is accompanied by the natural loss and wear of hard and soft dental tissues. While ageing can influence pathological processes affecting the dentition, it is not the cause of these processes. The development, growth, attrition, abrasion, and loss of teeth is determined in part by ageing. Periodontal disease is the result of the accumulation of dental plaque and can occur in young animals. Unfortunately, gingivitis or periodontitis is often not diagnosed or diagnosed too late by pet owners and veterinarians.  相似文献

Tooth brushing is considered a superior technique for reducing plaque accumulation. Other methods of maintaining oral hygiene have been investigated since many owners may not be willing or able to brush their dog's teeth. Following a professional teeth cleaning procedure, 11 dogs were offered a rawhide dental chew BID for 7-days, while 11 other dogs were fed the same diet without receiving the chew device. Dogs in the treatment group had significantly less plaque formation during the trial period compared with dogs in the control group. The rawhide dental chew provided in the study reported here decreases plaque formation in the short-term and may be beneficial in the prevention of progressive periodontal disease associated with attachment loss if provided on a long-term basis.  相似文献

The clinical and microbiological effects of zinc ascorbate gel applied orally in cats were evaluated during a 42-day study period. Cats were divided randomly into two equal groups, with the treatment group (18 cats) receiving zinc ascorbate gel and the control group (18 cats) receiving a placebo (0.9% sterile saline). Clinical parameters evaluated biweekly included halitosis, plaque, calculus, and gingivitis. Aerobic and anaerobic bacterial cultures were obtained from cats in the treatment group at Days 0 and 42. There was a significant decrease in plaque, gingivitis, and anaerobic periodontal pathogens in treatment group cats. Halitosis and calculus scores were not significantly different in treatment group compared with control group cats. The results of this study suggest that zinc ascorbate gel used as an oral antiseptic improves feline oral health, and may be most effective in decreasing bacterial growth, plaque formation, and gingivitis when applied following a professional teeth cleaning procedure.  相似文献

The aims of this study were to develop a dental evaluate any oral cavity disease, develop gypsum models of the dental arches, and to register the occlusions found in coatis (Nasua nasua) in captivity Formulation of the dental chart was assisted by intraoral radiographs from the head of an adult coati cadaver of the same species with the following dental formula.: I 3/3, C 1/1, P 4/3, M 2/2. Seven live coatis of the Nasua nasua species were evaluated. Five of the seven coatis presented with various dental abnormalities as follows: dental plaque (71.4 0%), gingivitis (71.4 %), periodontitis (57.1 %), dental stain (42.9 %), dental abrasion (57.1 %), dental fracture (57.1 %), pulp exposure (42.9 %), malocclusion (57.1 %) and supernumerary teeth (14.2 %).  相似文献

Periodontal disease is difficult to measure objectively. Many indices measuring plaque accumulation and gingivitis have been designed for humans, the Silness and L?e plaque index and Turesky modification of the Quigley and Hein plaque index being examples of well-accepted systems. It may, however, be beneficial to consider new or modified measurement systems for dogs, and such veterinary modifications need to be supported and clearly identified. This article reviews the origins of clinical periodontal indices now in common use in studies that examine the effectiveness of oral hygiene products.  相似文献

Any alteration in the balance of bacterial challenge versus the host's ability to resist and repair will result in oral lesions that are similar in appearance. The bacterial cause of gingivitis and periodontitis in humans and in all other animals in which it has been studied is firmly established, and specific species of predominantly gram-negative anaerobes have been implicated. Naturally occurring or acquired immunopathologies are likely to result in premature dental disease. When oral disease is associated with the accumulation of plaque, a positive response can be achieved by reducing the bacterial challenge to the host through the maintenance of oral hygiene by timely professional dental prophylaxis and home care. Disease that is the result of atypical immune responses, however, can be much more difficult to manage. Such oral disease can occur with either immune deficiencies or exaggerated immune responses, and it is likely that multiple mechanisms are active concurrently. In any case, gram-negative anaerobes present in plaque are likely to be a major contributing factor. Therefore patients with chronic refractory gingivitis-stomatitis must be considered to be plaque intolerant. Only with a frequent regimen of aggressive and thorough professional dental treatment plus meticulous oral home care on a daily basis can one expect to keep these cases in remission. Because this is often unrealistic, the only other way to keep these patients free of disease is by total dental extraction. The tissues that are colonized by the causative organisms must be eliminated. All root tips and bony sequestra must be removed and healing with intact epithelium accomplished before these cases will go into remission. Edentulous feline patients that continue to have signs of gingivostomatitis have been found to have an area of nonhealed bony sequestrum and chronic osteomyelitis. Once effective debridement has been accomplished and epithelial healing completed, nonresponsive cases can be expected to go into remission (Color Plate 2, Figure 7). It is hoped that as more is learned about this frustrating problem, the many factors influencing feline oral disease will be scientifically documented. In the future, actual diagnoses can be systematically made early on in disease, and treatment will be more than just symptomatic.  相似文献
