Forty female Beagle dogs, aged 12 to 24-months were divided into four groups of ten dogs each. Results showed that increasing kibble diameter by 50.0 % was associated with a 42.0 % calculus reduction. Coating the kibbles with sodium tripolyphosphate, an anti-calculus agent, further induced a 55.0 % calculus reduction. Sodium tripolyphosphate was shown to be at least as effective as sodium hexametaphosphate. The calculus reduction effect on teeth differed based on tooth location with the most…

TLDR
Daily administration of a palatable, xylitol drinking water additive that required little time and effort reduced plaque and calculus accumulation in dogs.
Nutrition as a Tool to Control Periodontal Diseases in Dogs and Cats
TLDR
The relationship between food and alteration in oral health has been studied and it is well established that soft foods are associated with increased frequency and severity of periodontal diseases, and that harder diets promote a mechanical removal of bacterial plaque.
Dental Wax Decreases Calculus Accumulation in Small Dogs
TLDR
A dental wax was evaluated after unilateral application in 20 client-owned, mixed and purebred small dogs using a clean, split-mouth study model and owners considered the wax easy to apply in all dogs.
Validation of Quantitative Light-Induced Fluorescence for Quantifying Calculus on Dogs’ Teeth
TLDR
This study demonstrated that QLF is a sensitive and precise method for quantification of calculus on dogs’ teeth and removes the subjective element of human examiners and has greater accuracy and reduced variability through the continuous nature of the data.
Influence of Diet Type on Oral Health of Dogs
TLDR
The results suggest that oral health problems are more likely to be seen in older animals and feeding dogs with dry food decreases the occurrence of periodontal diseases.
Effects of Erosion Protocol Design on Erosion/Abrasion Study Outcome and on Active Agent (NaF and SnF2) Efficacy
TLDR
Movement type, pH and concentration of acid had a substantial impact on study outcome, and the combination of jerky movement and concentrated acid masked, to some extent, differences between erosives and erosive-abrasive tissue loss.
Maladies parodontales chez le chien : facteurs de risque et approches thérapeutiques
TLDR
Small size dogs must be particularly observed and and closely followed up for dental hygiene and periodontal treatment depends on dental hygiene, which is mandatory for preventing uncontrolled plaque accumulation.
Periodontal disease in cats
TLDR
Treatment for periodontitis in cats aims to control tissue inflammation, returning the gingiva to clinical health and preventing destruction of the periodontium in other parts of the mouth.
Effect of age on dental plaque deposition and its control by ultrasonic scaling, dental hygiene chew, and chlorhexidine (0.2%w/v) in dogs
TLDR
The study showed a strong positive relationship between age and plaque deposition and gingivitis, and showed that oral hygiene measures such as use of dental hygiene chew and chlorhexidine application can reduce plaque deposit and periodontitis in domesticated canines.
The impact of home-prepared diets and home oral hygiene on oral health in cats and dogs.
TLDR
Feeding only a dry diet was beneficial for oral health in cats and dogs and tooth brushing and the offering of dental treats were very effective in maintaining oral health, provided they were practised daily.

Effect of sodium hexametaphosphate on dental calculus formation in dogs.
TLDR
It is concluded that the coating of dry dog chow or plain dog biscuits with HMP is an effective means of reducing calculus formation in dogs.
Hexametaphosphate-Coated Snack Biscuits Significantly Reduce Calculus Formation in Dogs
TLDR
A clinical trial in beagle dogs found that feeding two or four conventional bone-shaped biscuits exerted no significant effect upon calculus formation, while the similar feeding of two HMP-coated biscuits significantly reduced calculus formation.

TLDR
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.
Reduction in Accumulation of Plaque, Stain, and Calculus in Dogs by Dietary Means
TLDR
Dogs fed the treatment food had significantly less plaque, stain, and calculus accumulation than dogs fed the control food, and the results reported as a combined mean for all treatment and control groups.
Influence of an anticalculus mouthrinse treatment on the dentition and periodontium in beagle dogs.
TLDR
The results from this investigation suggest that it is possible to mitigate both probing epithelial attachment loss and increases in probing pocket depth at the calculus prone sites through the use of an anticalculus mouthrinse.

TLDR
The structure of polypyroph phosphate as compared to the parent pyrophosphate molecule, the rationale for its improved chemistry, and, in particular, its tartar control chemistry are described.
Effects of a Dental Food on Plaque Accumulation and Gingival Health in Dogs
TLDR
Daily feeding of a dental food significantly reduced plaque and gingivitis in dogs during a 6-month period, compared with daily feeding of the typical dry food.

TLDR
Salivary proteins selectively adsorb on the tooth surface to form an acquired pellicle, and Supersaturation of saliva and plaque fluid with respect to calcium phosphates is the driving force for plaque mineralization.
Association of Age and Body Weight with Periodontal Disease in North American Dogs
TLDR
Missing teeth, mobility of remaining teeth, extent of calculus and gingival inflammation, and furcation exposure and attachment loss all were more common in small dogs compared with larger dogs, and in older dogsCompared with younger dogs.
Long Term Effects of a Dental Hygiene Chew on the Periodontal Health of Dogs
TLDR
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 professionalperiodontal intervention.
