Success in veterinary dentistry lies in good home care and regular, thorough dental prophylaxis. The removal of supragingival and subgingival calculus must be accomplished before periodontal disease can be controlled. When gingival sulcus depths exceed 4 or 5 mm, the gingivae must be excised or reflected to allow proper treatment of the pocket area. Antibiotic therapy should be instituted in the extensively involved veterinary dental patient. 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

Periodontal disease and chronic gingivitis/stomatitis are the most common feline dental diseases. With routine dental care and increased emphasis on home oral hygiene, these diseases can be controlled. Cats can be seen with a number of other dental disorders, and improved treatment methods such as restorations of early subgingival resorptive lesions, endodontic therapy, and orthodontic therapy can be performed successfully. More study and research are necessary about the gingivitis/stomatitis syndrome and subgingival resorptive lesions so that improved prevention and treatment recommendations can be made. 相似文献

Periodontal disease is the most common disease in small animal patients. It not only creates severe localized infection, but it has been linked to numerous severe systemic maladies. Proper therapy of this disease process results in a significant increase in the overall health of the patient. The treatment of periodontal disease is currently evolving due to the acceptance of the specific plaque hypothesis of periodontal disease. These findings have led to the development of the "one-stage full-mouth disinfection" treatment as well as a vaccine against these organisms. However, the cornerstone of therapy is still meticulous plaque control. This control is achieved via a combination of regular dental prophylaxis and home care. With progressive disease, advanced periodontal surgery or extraction becomes necessary. 相似文献

Periodontal disease is common in dogs and cats. Prevention and treatment is important for general health and well-being of our pets. Both prevention and treatment of periodontal disease have two components, namely maintenance of oral hygiene and professional periodontal therapy. Maintenance of oral hygiene is performed by the owner and is, therefore, also called home care. The preventions and long-term control of periodontal disease requires adequate home care. This chapter details home care techniques and available products. 相似文献

In a perfect world, all veterinarians and veterinary dental technicians would understand periodontal disease as well as the dental specialist. They would all be able to recognize the early signs of periodontal disease and recommend treatment to prevent its progression. The owners would have the financial resources, time, and desire to maintain their pet's oral health. The dogs would all be calm and compliant with home care and have no particular anesthetic risks. Unfortunately, this is not a perfect world. Some veterinarians do not understand periodontal disease any better that I understand cosmic string theory. Some owners have limited financial resources and are not particularly committed to their pet's oral health. Some animals will not tolerate any type or manner of home care. Given that animals, their mouths, and their owners come in an infinite variety of shapes and sizes (figuratively and literally), how can we talk about the treatment of periodontal disease as if it is a single condition with a single treatment, or even only a few treatment options? Each owner, animal, and its environment must be assessed on an individual basis to develop a treatment plan that is reasonable and attainable based on the unique circumstances of each case. So, what should be the goal when treating periodontal disease? Is it the preservation of all teeth at all costs? Is it the preservation of important teeth if the costs can be kept reasonable? I would suggest that the overriding goal of periodontal treatment should be the elimination and prevention of oral infection and oral pain. In the domestic environment, dogs have no real need to defend territory. They have no need to prehend and kill live prey animals. In short, the domesticated pet dog does not need teeth at all. This may seem like an odd statement for a veterinary dentist to make, but I feel quite strongly that a dog is far better off having no teeth than having bad teeth. My preference is that a dog should have a full set of healthy, functional teeth, but preserving bad teeth in the face of a poor or questionable prognosis serves no positive purpose. 相似文献

Feline periodontal disease has many elements in common with human and canine disease. Anatomic, physiologic, microbiologic, and immunologic differences between the three species make it impossible to predict with certainty whether successful approaches to controlling and treating canine oral disease will also prove successful in cats. We have developed methods for reproducible, quantitative evaluation of feline dental plaque and calculus. Our studies demonstrated that feline plaque accumulation peaks at 1 week after prophylaxis and that calculus peaks at 4 weeks after prophylaxis. These methods should be adequately sensitive to document control of plaque and calculus accumulation by efficacious chemical or antimicrobial agents. 相似文献

Periodontal disease is a painful and highly prevalent disorder of horses that causes a significant welfare problem. Despite its importance, few scientific studies on its aetiopathogenesis have been performed. Equine periodontitis differs from the plaque‐induced periodontitis found in brachydont species where bacteria accumulating in dental plaque induce a destructive inflammatory response in the periodontium. In contrast, equine periodontitis is usually initiated by entrapment of feed between cheek teeth, which causes inflammation of periodontal tissue that likely allows bacterial infection of the periodontal tissues that is later exacerbated by the host's response. Equine oral microbiology is a neglected field of research and identification of the bacteria involved in this disorder by use of molecular bacteriology and examination of the interaction between these bacteria and the equine oral immune response should reveal important information about the pathogenesis of this disease. 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

Periodontal examinations were performed on ten 1- to 22-year-old snow leopards (6 males and 4 females), using dentistry methods for determining the plaque and gingival indices. All tooth surfaces were probed, and alveolar bone attachment loss was determined. After subgingival plaque removal, plaque specimens were examined for differential bacterial morphotypes. The small number of leopards evaluated precluded definitive statistical analysis. However, the progression from gingival health to gingivitis to periodontitis was similar to that seen in man. Therefore, the use of plaque index, gingival index, alveolar bone attachment loss, and differential bacterial morphotypes can be used to determine the dental health of snow leopards. 相似文献

Dental, oral, and maxillofacial diseases are some of the most common problems in small animal veterinary practice. These conditions create significant pain as well as localized and potentially systemic infection. As such, the World Small Animal Veterinary Association (WSAVA) believes that un- and under treated oral and dental diseases pose a significant animal welfare concern. Dentistry is an area of veterinary medicine which is still widely ignored and is subject to many myths and misconceptions. Effective teaching of veterinary dentistry in the veterinary school is the key to progression in this field of veterinary medicine, and to the improvement of welfare for all our patients globally. These guidelines were developed to provide veterinarians with the information required to understand best practices for dental therapy and create realistic minimum standards of care. Using the three-tiered continuing education system of WSAVA, the guidelines make global equipment and therapeutic recommendations and highlight the anaesthetic and welfare requirements for small animal patients. This document contains information on common oral and dental pathologies, diagnostic procedures (an easily implementable and repeatable scoring system for dental health, dental radiography and radiology) and treatments (periodontal therapy, extractions). Further, there are sections on anaesthesia and pain management for dental procedures, home dental care, nutritional information, and recommendations on the role of the universities in improving veterinary dentistry. A discussion of the deleterious effects of anaesthesia free dentistry (AFD) is included, as this procedure is ineffective at best and damaging at worst. Throughout the document the negative effects of undiagnosed and/or treated dental disease on the health and well-being of our patients, and how this equates to an animal welfare issue, is discussed. 相似文献

The human oral microbiome is known to play a significant role in human health and disease. While less well studied, the feline oral microbiome is thought to play a similarly important role. To determine roles oral bacteria play in health and disease, one first has to be able to accurately identify bacterial species present. 16S rRNA gene sequence information is widely used for molecular identification of bacteria and is also useful for establishing the taxonomy of novel species.The objective of this research was to obtain full 16S rRNA gene reference sequences for feline oral bacteria, place the sequences in species-level phylotypes, and create a curated 16S rRNA based taxonomy for common feline oral bacteria.Clone libraries were produced using “universal” and phylum-selective PCR primers and DNA from pooled subgingival plaque from healthy and periodontally diseased cats. Bacteria in subgingival samples were also cultivated to obtain isolates. Full-length 16S rDNA sequences were determined for clones and isolates that represent 171 feline oral taxa. A provisional curated taxonomy was developed based on the position of each taxon in 16S rRNA phylogenetic trees.The feline oral microbiome curated taxonomy and 16S rRNA gene reference set will allow investigators to refer to precisely defined bacterial taxa. A provisional name such as “Propionibacterium sp. feline oral taxon FOT-327” is an anchor to which clone, strain or GenBank names or accession numbers can point. Future next-generation-sequencing studies of feline oral bacteria will be able to map reads to taxonomically curated full-length 16S rRNA gene sequences. 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.

牙周病(periodontal disease, PD)是由细菌在牙齿表面聚集形成的牙菌斑和牙结石逐渐侵蚀牙周组织,引发周围组织炎症的一类疾病。根据疾病的发展进程,可分为齿龈炎与牙周炎2个阶段。在小动物临床疾病中牙周病尤为常见,世界范围内约有80%的成年犬患有该病。由于饲主对于犬的口腔保健意识薄弱且该疾病隐秘性较高,患犬就诊时往往已出现牙周支持组织不可逆的损伤,细菌及其毒力因子通过血液循环进入全身从而引发系统性疾病的风险大大提高。但目前犬牙周病的核心致病菌属、菌群失调的原因与发病机制尚不明确。因此,笔者基于高通量测序方法的病原学研究结果,分析与疾病发展相关的微生物群。同时,整合目前世界通用的最新犬牙周病临床诊断分级标准及犬牙周病的中西医防治方案,分析犬牙周病与全身系统性疾病之间的相关性,系统综述犬牙周病在国内外小动物临床领域的研究进展,以期为该类疾病的临床诊疗提供理论参考,推进兽医师在临床实践中更高效地开展该类疾病的诊疗工作,并为犬牙周病相关的临床研究提供思路。 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 sound knowledge of dental and periodontal anatomy provides the basis for an accurate diagnosis of dental abnormalities. It must be remembered that dental and periodontal anatomy, especially in the horse, undergoes continuous morphological changes throughout life. From birth to age about 6 years the deciduous and later the permanent teeth emerge in turn through the oral mucosa. Even the permanent dentition is subjected to continuous, dynamic, morphological changes due to massive occlusal wear and the compensatory tooth eruption that is necessary in herbivores. Consequently, it is not surprising that the normal equine oral anatomy of structures shows a wide range of variations. The purpose of this tutorial article is to review and summarise the current knowledge of equine dental and periodontal anatomy, paying special attention to age related morphological changes. 相似文献

Objective — This study evaluates the association between dental procedures and bacteremia in dogs, including a comparison of bacteria isolated from plaque and blood, severity of the bacteremia versus the severity of dental disease, and the longevity of bacteremia.
Study Design — Bacteria cultured from the blood over time were compared with those isolated from the plaque and crevicular fluid and in relation to severity of dental disease.
Animals or Sample Population — Twenty adult greyhounds.
Methods — Blood samples were collected for culture before induction of general anesthesia, immediately after intubation, 20 minutes after initiation of the dental procedure, and at 10-minute intervals until 10 minutes after the dental procedure was completed. Samples of plaque were taken for microbiological culture.
Results — Sixty to ninety percent of the bacterial genera isolated from the plaque were present in the blood. Dogs classified according to severity of dental disease showed no difference in the total number of different species or number of different Gram-negative, Gram-positive, or anaerobic bacteria isolated from plaque or blood (P <.05). Bacteremia was present in all of the dogs studied, within 40 minutes from the initiation of the dental procedure, regardless of the severity of oral disease.
Conclusions — Gram-negative, Gram-positive, and anaerobic bacteria are present in blood during dental procedures; the bacteremia can persist beyond the dental procedure, and is not associated with the severity of dental disease.
Clinical Relevance — The nature and extent of bacteremia occuring during routine dental procedures is important in understanding a potential risk to dogs. 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

The periodontal health status was assessed in two groups of dogs which had received different levels of periodontal care over a two-year period. The dental group received regular dental scaling and polishing, and intermittent daily tooth brushing, while the control group received no periodontal care. All dogs developed gingivitis, and two (one from each group) showed evidence of incipient periodontitis. The dental group had a reduced gingivitis index (GI) compared with the control group only when they had received daily tooth brushing before the GI assessment. When the dogs had not had their teeth brushed for four weeks before the assessment, the GI was not significantly different to that in the control dogs. This suggests that continual periodontal care throughout life is of great importance and questions the benefits of intermittent oral care. The GI of the palatal and lingual surfaces in all dogs was significantly higher than the GI of the buccal surfaces. Thus, all tooth surfaces may need to be cleaned to achieve optimal periodontal health. 相似文献

Diastema (pleural diastemata) is the most common disorder predisposing the horse to periodontal disease. These can affect the incisors or cheek teeth but pose more significant problems in the cheek teeth. Cheek teeth diastema can be congenital or develop secondary to other pathology. This condition is underdiagnosed in clinical practice due to lack of awareness of its seriousness and also due to poor dental examination techniques. A thorough dental examination requires both digital palpation and visual inspection of the oral cavity. Proper patient restraint and the use of a mouth speculum, bright light source, dental mirror or oral endoscope are required to fully inspect the equine oral cavity. Diastemata diagnosed early and managed properly can prevent the progression of periodontal disease and allow affected horses to preserve their dentition into old age. 相似文献
