Periodontal disease has not been well characterized in the cat, and it is not known if feline tooth resorptions (TR) are equivalent to those observed in humans and dogs. The aim of this study was to investigate the different patterns of periodontal inflammation in cats, and to evaluate their prevalence in a standardized healthy population (n = 109). Particular emphasis was placed on the potential associations between TR and periodontal parameters, as well as the influence of potential risk factors (including breed, sex, and age). A single complete periodontal examination was performed, including periodontal probing of each tooth and exploration of the tooth surface using a dental explorer; at least 10 radiographs were taken for each cat. Missing teeth with radiographic evidence of root apices were present in 34.0% of cats. Periodontal disease was common, and 13.0% of cats had aggressive periodontitis. All of the cats had some form of periodontal inflammation, and only 4.0% of cats were free from gingival inflammation. Moderate to severe gingivitis was present in 13.0% of teeth. Dental furcation exposure was present in 18.0% of all multi-rooted teeth. Periodontal bone loss was observed in 31.2% of teeth, with the majority (98.2%) of all cats having some form of periodontal bone loss. Breed effects were identified for some variables. Eight of 14 periodontal variables were statistically correlated with Type 1 TR. Two of 14 variables (and age) were statistically correlated with Type 2 TR. In conclusion, the cats of this colony had a wide range of periodontal inflammation, including aggressive periodontitis. Type 1 TR and Type 2 TR were identified to be two significantly different manifestations of TR, with a strong association between Type 1 TR and periodontal disease.
Chronic gingivostomatitis (bucco-stomatitis, faucitis) in cats is a severe but ill-defined entity with poor response to medical treatment. Thirty cats were treated by extraction of most or all of the premolar and molar teeth. Twenty four of the 30 cats (80%) were significantly improved or clinically cured at the time of follow-up, 11–24 months following treatment
Chronic caudal stomatitis with alveolar/buccal mucositis in calicivirus-positive cats is the most severe presentation of feline chronic gingivostomatitis. Refractory cases are helped by antibiotic and anti-inflammatory treatments often including glucocorticoids. In order to evaluate the comparative efficacy of oromucosal administration of recombinant feline interferon omega (rFeIFN-ω) versus oral administration of glucocorticoids, a randomised, multi-centre, controlled, double-blind study was performed in 39 cats. The progression of behavioural, clinical and lesional scores was assessed over 90 days. Daily oromucosal treatment with 0.1 MU of rFeIFN-ω was associated with a significant improvement of clinical lesions (caudal stomatitis and alveolar/buccal mucositis) and a decrease of pain scores from D0 to D90. Although no such statistical improvement was noticed in the prednisolone group, there was, however, no significant difference between the two groups for most of the parameters, except pain at D60 and D90.
Piezoelectric bone surgery is a recent and innovative technology, permitting a selective cut of mineralized tissue while sparing soft tissue. Similar to a dental scaler, a high frequency vibration, in the range of 25–35 kHz, is transmitted to a metallic tip. However, the power of the piezosurgical instrument is three to six times higher than that of a dental scaler. The major advantages of this technology include high precision, a design that increases ease of curvilinear osteotomy, less trauma to soft tissue, preservation of neurological and vascular structures, reduced hemorrhage, minimal thermal damage to the bone, as well as overall improvement of healing. The handpiece of the instrument is equipped with a sterile irrigation system and light-emitting diode (LED) light, which improves visibility and overall safety. Piezoelectric surgery is particularly useful when performing delicate bone procedures such as periodontal or endodontic surgery. It is also indicated when performing more invasive bone surgery such as maxillectomy, mandibulectomy, and condylectomy, where preservation of neurovascular structures is important. Piezoelectric instruments are different from rotary instrumentation or oscillating saws, they require light pressure with constant motion of the tip. Training is required to master the technique.
Numerous types of veterinary orthodontic treatments are reported in papers and during meetings, however little is generally known concerning craniofacial growth in dogs. Most statements in veterinary dental publications are drawn from human-oriented studies. This makes decision making in veterinary orthodontics difficult. The purpose of this paper is to review studies of craniofacial growth performed in dogs.
ObjectiveThis study was performed to assess the relationship between oral Feline calicivirus (FCV) load and severity of lesions at the time of presentation of cats suffering from feline chronic gingivostomatitis (FCGS) (part 1) and treatment outcome after dental extractions (part 2). We hypothesized that a higher FCV viral load would be positively correlated with the severity of lesions at presentation and negatively correlated with treatment outcome. In addition, the effect of dental extractions on outcome and the influence of preoperative severity of lesions on the outcome were investigated.Materials and methodsCats with FCGS were included in the study if they had been diagnosed with caudal stomatitis, had been tested positive for FCV using a real-time reverse transcriptase-PCR test on oropharyngeal swab, and had dental extractions performed within the authors’ department. General practitioners provided all previous medical treatments. Cats with recheck examinations were included in part 2 of the study. Multivariate statistical analysis was performed to assess the relationship between the different parameters.ResultsOne hundred four cats met the requirements for part 1 and 56 cats for part 2 of the study. Data collected from patients’ record included patient history, viral testing results, extent and severity of oral lesions, extent of teeth extraction. Signalment, history, preoperative treatment, and severity of caudal and alveolar stomatitis score were not associated with FCV load (P > 0.05). Presence of lingual ulcers was significantly correlated with FCV load (P = 0.0325). Clinical cure (32.1%) or very significant improvement (19.6%) was achieved in 51.8% of cats within 38 days. Concomitantly, 60.7% of the owners considered their cat cured (41.1%) or significantly improved (19.6%). Extent of teeth extraction was not found to influence the clinical outcome (P > 0.05).ConclusionThe results of this study did not support the hypothesis that FCV oral load is correlated with the severity of oral lesions or with the outcome following dental extractions. In addition, the severity of caudal inflammation was not correlated with healing time or achievement of cure.
