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

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

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 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

Objectives

To determine the incidence and rates of progression of gingivitis and periodontitis in Labrador retrievers.

Materials and Methods

Fifty‐three dogs, aged 1·1 to 5·9 years, had their periodontal health assessed every 6 months for up to 2 years. The extent of gingivitis and periodontitis was measured around the whole gingival margin of every tooth under general anaesthesia.

Results

All dogs had gingivitis at the initial assessment. The majority (64·2%) of tooth aspects had very mild gingivitis. The palatal/lingual aspect of all tooth types was most likely to show bleeding when probed: 63·0% of these aspects had mild or moderate gingivitis. Over 2 years, 56·6% of dogs developed periodontitis and dogs as young as 1·9 years were affected. There was a significant positive correlation between the proportion of teeth with periodontitis and age. In total, 124 teeth (5·7%) developed periodontitis; 88 (71·0%) of these were incisors. The palatal/lingual aspect of the incisors developed the disease first (2·8% of incisor aspects).

Clinical Significance

Periodontitis developed in regions that are difficult to see in conscious dogs implying that detection and treatment of disease requires periodic sedation or anaesthesia.  相似文献

OBJECTIVE: To determine the diagnostic value of 2 intraoral bisecting angle radiographic views in comparison with periodontal probing for the assessment of periodontal attachment of the canine teeth in dogs. STUDY POPULATION: 466 canine teeth from 117 dogs. PROCEDURE: Periodontal probing measurements were recorded, and clinical attachment levels (CAL) were calculated at the mesial, buccal, distal, and lingual (or palatal) surfaces on each canine tooth. Occlusal and lateral radiographs of the canine teeth were obtained. Alveolar margin height (AMH) was measured at the same 4 surfaces. Values for AMH and CAL were compared on the basis of tooth surface, dental arch, and radiographic view. RESULTS: The AMH at the mesial and distal surfaces of the mandibular canine teeth was measurable on the lateral view and was significantly correlated with CAL. Similar results were found for the mesial and distal surfaces of the maxillary canine teeth. Buccal and lingual AMH were measured on the mandibular occlusal radiographic view, and values were significantly correlated with CAL, but only the buccal AMH could be assessed on the occlusal radiographic view of the maxilla with values that correlated significantly with CAL. CONCLUSIONS AND CLINICAL RELEVANCE: The lateral radiographic view is suitable for evaluating periodontal attachment at the mesial and distal surfaces of the canine teeth in dogs. The occlusal radiographic view is suitable for assessing buccal surfaces as well as the lingual surface of mandibular canine teeth but not the palatal surface of maxillary canine teeth in dogs.  相似文献

Twenty client-owned dogs diagnosed with gingivitis were studied over a 45-day period in order to investigate the effect of professional dental prophylaxis combined with the use of a topical mucoadhesive gel containing adelmidrol, an aliamide. A non-intrusive papillary-marginal-gingival index (PMGI) was measured at each assessment, while the gingivitis index (GI) was measured only at the beginning and end of the study. Compared to the control group, the treated dogs had a significant decrease (P < 0.005) in the average GI index during the course of the study. A significant reduction (P < 0.002) in the average PMGI index was observed in both groups 15-days following dental prophylaxis. However at 30 and 45-days following dental prophylaxis, the PMGI index values were significantly different (P < 0.005) from baseline only in treated dogs. These results suggest that the combined use of a mucoadhesive gel with dental scaling was able to improve the regression of gingival inflammation and lengthen the therapeutic benefits of dental scaling and polishing during a limited study 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

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

In this study, scaling, polishing and daily tooth brushing were performed in 20 beagle dogs, and the number of oral bacteria was determined using a bacterial counter. The dogs were randomized into the scaling (S), scaling + polishing (SP), scaling + tooth daily brushing (SB) and scaling + polishing + tooth daily brushing (SPB) groups. Samples were collected from the buccal surface of the maxillary fourth premolars of the dogs immediately after scaling and every week thereafter from weeks 1 to 8. Throughout the study, the number of bacteria was significantly lower in the SB and SPB groups compared with the S group. The findings suggest that daily tooth brushing inhibited oral bacterial growth in the dogs.  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 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

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

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

The primary etiology of periodontal disease is bacterial infection. Bacteria exist as a biofilm (plaque) on the tooth and soft-tissue surfaces of the mouth. Biofilm is extremely resistant to antimicrobial activity. To effectively treat periodontal disease, the bacterial load must be reduced to allow healing of the inflamed tissues. Reduction of the bacterial load can be accomplished by surgical methods, nonsurgical methods, or a combination of the two. This article focuses on the nonsurgical treatment of periodontal disease. A thorough oral examination, which includes visual inspection and the use of a periodontal probe, is needed to determine the best therapy. Supragingival cleaning with power and hand scalers is the first step in the therapy process. The next step, subgingival scaling, is necessary to remove bacteria that are in direct contact with the periodontium. Effective subgingival plaque removal is time intensive and requires motivation, manual dexterity, and meticulous technique. Most veterinarians and veterinary technicians lack the training, instruments, and time to remove subgingival plaque effectively. To improve therapeutic results, adjunctive therapy in the form of oral systemic antibiotics or a locally applied doxycycline-containing polymer may be used. The success of periodontal therapy also is dependent on dental home care that takes place after professional treatment. The veterinarian and staff must be willing to educate and reinforce the dental home care efforts of the pet owner.  相似文献

Recent studies have demonstrated that typical dry dog foods have significantly less efficacy in reducing accumulation of dental substrates compared to a specifically formulated and processed dental food. This study compared the effects of a typical dry food and a dental food on plaque accumulation and gingival inflammation in dogs during a 6-month period. Daily feeding of the dental food significantly reduced plaque and gingivitis by 39% and 36%, respectively, compared with daily feeding of the typical dry food. Feeding a food that decreases plaque accumulation and reduces gingivitis contributes to canine oral health maintenance.  相似文献

The aims of this study were to determine the impact of body site, vigorous brushing and topical melatonin treatment on hair regrowth after clipping normal dogs. Siberian Husky dogs were randomly assigned to three groups of eight dogs each. All dogs had the lumbosacral region and both lateral thighs clipped. The left thigh and lumbosacral area received no treatment and were compared in all 24 dogs. Eight dogs had the right thigh treated with 0.1% melatonin twice daily for 2 months, and hair regrowth was compared with the left thigh. Eight dogs had the right thigh brushed twice daily for 2 months, and hair regrowth was compared with the left thigh. Eight dogs had neither thigh treated. Hairs were plucked before and 2 months postclipping, and the proportion of hair growth from the original length was calculated and compared as described above. Biopsy samples were collected before and after treatment to determine if brushing induced dermal inflammation and melatonin increased the proportion of anagen follicles. Proportionally, left thigh hairs were significantly longer compared to lumbosacral hairs 2 months postclipping. No significant differences in hair regrowth were noted between the nontreated thigh and the thigh treated with melatonin or brushed. No significant difference in dermal inflammation was noted before and after brushing. No significant differences were observed in the proportion of anagen follicles before and after topical melatonin treatment. Our results showed that the hairs in the lumbosacral region were proportionally shorter than lateral thigh hairs 2 months postclipping. Moreover, topical melatonin and brushing had no impact on hair regrowth after clipping normal dogs.  相似文献

OBJECTIVE: To determine whether gingival crevicular fluid (GCF) and serum total antioxidant capacities (TACs) correlate with the degree of severity of periodontal disease in dogs. ANIMALS: 41 Toy and Miniature Poodles. PROCEDURES: After assessment of the degree of severity of naturally occurring periodontitis, GCF samples from both maxillary fourth premolars and a blood sample were collected from each dog. The condition of the periodontium of the entire dentition and at each site of GCF collection was recorded. Clinical parameters assessed included plaque index, gingival index, and probing depth. Radiographic analysis of alveolar bone level was also performed. Total antioxidant capacity was measured in GCF and serum samples by use of a commercial kit. RESULTS: Dogs with gingivitis and minimal periodontitis had significantly higher TAC in GCF than dogs with advanced periodontitis. Bivariate regression analysis revealed significant negative correlations between TAC in GCF and clinical parameters and age. The TAC in serum was significantly negatively correlated with the degree of gingival inflammation but was not significantly correlated with age. CONCLUSIONS AND CLINICAL RELEVANCE: TAC in GCF is related to the degree of severity of periodontal disease in dogs. This is likely the result of release of reactive oxygen species by activated phagocytes and fibroblasts in the inflamed periodontal tissues. The results of our study suggest that the local delivery of antioxidants may be a useful adjunctive treatment for periodontitis in dogs.  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

The clinical development of broken mouth over a single reproductive year and the effect of two broad spectrum antibacterial agents upon it was followed in 72 Scottish Blackface ewes aged between two and three years. Using a number of dental health indices especially developed for the purpose, the amount of gingivitis, tooth movement, gum recession and pocketing were quantified and graphed for both the whole population and each group in the drug trial. All clinical features except movement fluctuated significantly with time, the fluctuations often being associated with nutritional or other environmental factors. Despite the extended use of large doses of two antimicrobial agents no significant reduction in the amount of clinical gingivitis or pocketing was evident.  相似文献
