New Products Added to the VOHC Accepted List
Milk-Bone Brushing Chews for Dogs, manufactured by the DelMonte Corporation, has been added to the VOHC Accepted Product list in the Helps Control Tartar category. The product is available in three sizes. Canine Greenies Chews in a Hip and Joint Care formulation have been added to the VOHC Accepted Product list. Clarification Science Diet Oral Care for Dogs has met the VOHC testing standard and been awarded the VOHC Seal in the Plaque and Tartar categories. The product packaging in early 2014 does not carry the Seal because of a delay on VOHC's part in completing review of a change in the product formulation that does not affect the dental efficacy of the product.
New Product Added to the VOHC Accepted List
Virbac CET Tartar Control Chews for Dogs, in several sizes, has been added to the VOHC Accepted Product list in the Helpd Control Tartar category. VOHC Policy Change Following the period of public comment on the proposed change in VOHC policy on Segmentation of Teeth During Scoring in VOHC Trials (see May 2013 News item), with no comments received, the policy change is now in effect.
VOHC Policy on Segementation of Teeth during Scoring in VOHC Trials
Use of vertical segmentation will not be accepted in VOHC trials. Either whole tooth or horizontally segmented tooth surfaces can be used for scoring. Only the scores from the gingival half of the tooth are to be considered in the analysis when horizontal segmentation is used.
The specific VOHC Recommendation is:
2. Evaluation of the Logan and Boyce Plaque Index for the Study of Dental Plaque Accumulation in Dogs. Hennet P, Servet E, Salesse H, Soulard Y: Res Vet Sci, 80, 175-180, 2006. Summary: The objectives of this study were to assess intra-examiner (experienced examiner) and inter-examiner agreements (experienced versus non-experienced examiners) of scores assessed with the Logan & Boyce plaque index and to evaluate whether a modification of this index, where anatomical landmarks are used for horizontal division [mod L&B-AL] and dye references are used for assessing intensity of dye (plaque thickness) [mod L&B-DR], would improve repeatability. The Logan & Boyce index was found to be inaccurate when scoring plaque coverage as it underestimated the total crown surface. The contribution of the gingival part to the total tooth score was minimized by the Logan & Boyce index compared to the mod L&B-AL/DR. Precision of global plaque scorings was significantly improved by the mod L&B-AL/DR. Intra-examiner agreement of plaque thickness and plaque coverage scorings on the gingival part of the tooth was significantly improved by the mod L&B-AL/DR. Studies evaluating plaque accumulation in dogs should therefore use the mod L&B-AL/DR rather than the Logan & Boyce index.
Brushing Policy for Cats
VOHC Trials Involving Tooth Brushing in Cats
What Brush to Use in Cats:
Brushing Strokes for Cats:
Assignment to groups:
Pre-trial Screening Examination for Cats in VOHC Trials:
Cats are to be pre-screened by an awake oral examination consisting of visual inspection of the buccal surfaces of the teeth required to be scored in a VOHC trial (upper C, P3, P4, lower C, P3, P4, M1) - the teeth are not touched with an instrument during the inspection.
Any cats with the following findings are to be excluded from the pool for assignment to one of the trial groups:

Change in VOHC Standard
The Board of Directors of the American Veterinary Dental College approved a recommendation from the Veterinary Oral Health Council to change the standard required for awarding the VOHC Accepted Seal.
This change is effective from January 1st, 2011.
Purpose of the Change:
New VOHC standard, as of January 1st, 2011:
Reduction (VOHC efficacy %) is defined as:
([Control group mouth mean] minus [Test group mouth mean]) divided by (Control group mouth mean) x 100
Impact on products that currently carry the VOHC Accepted Seal:
Healthymouth, an anti-plaque water additive, has been added to the VOHC accepted list in the Plaque claim category for dogs.
The Board of Directors of AVDC accepted a recommendation from Council to add the following statement to the Safety and Regulatory Issues statement at the bottom of the Protocol page:
'Safety ' in the VOHC context includes:
A. Major extra-oral or body-wide issues such as toxicity, esophageal or gastro-intestinal obstruction or perforation, or gross nutritional imbalance;
B. Trauma to oral tissues, such as fracture of teeth or laceration or penetration of oral mucosa.
Complaints from consumers that relate to any of the product safety issues mentioned above are to be promptly copied to VOHC, and annual confirmation of continuation of use of the VOHC Accepted Seal is contingent on affirmation that no safety complaints that have not already been brought to VOHC's attention have been received by the product sponsor.
VOHC Accepted Seal awarded to Vetradent's Baby Bluechews and dc TinyToy Dental Chews in the Tartar claim category. VOHC Accepted Seal awarded to Diamond Food's Bright Bites and Checkups Dog Treats, all sizes, in the Plaque and Tartar claim categories.
VOHC Accepted Seal awarded to Canine Greenies Senior and Canine Greenies Lite dog treats, all sizes, in the Plaque and Tartar claim categories.
Dogs do love to chew...... World series ball eaten by dog Thurs., Dec. 20, 2007 BOSTON - The World Series ball is gone, and Jonathan Papelbon has an excuse: My dog ate it. Farfetched or not, that's what the Red Sox closer insists happened to the souvenir from the final out of Boston's sweep this year. Really, Papelbon blamed it on his bulldog, Boss. "He plays with baseballs like they are his toys," Papelbon told the Hattiesburg (Miss.) American. "He jumped up one day on the counter and snatched it. He likes rawhide. He tore that thing to pieces. I'll keep what's left of it."
New Canine Greenies Treat is awarded the VOHC Seal of Acceptance for Plaque and Tartar. New Canine Greenies is available in five sizes.
Tartar Shield Soft Rawhide Chews is awarded the VOHC Seal of Acceptance for Tartar. Tartar Shield Chews are available in five sizes.
Feline Greenies has been removed from the VOHC Accepted list because the manufacturers have changed the formulation, and the old formulation is no longer in stock at point-of-purchase.
VOHC Council approved use of the Gingival Contour Plaque Index scoring system ( described by Scherl et al in the March 2007 issue of the Journal of Veterinary Dentistry), provided that the plaque score and calculus score in each dog on day 0 of the trial is zero. In a related item, VOHC changed the minimum seven day trial period for plaque by adding: unless a scoring method validating a shorter period has been previously approved by Council.
The Canine Greenies formulation that was awarded the VOHC Accepted Seal in 2004 has been withdrawn from the market, and the listing for Canine Greenies has been removed from the VOHC Accepted list.
Upon the recommendation of VOHC Council, the AVDC Board of Directors has ratified changes in protocols:
Clarified wording on use of segments of teeth when scoring.
Adopted a safety requirement for chemical agents included as plaque or tartar inhibitors.
Eliminated the need for three arm/leg trials when evaluating products with both mechanical and chemical effects.
Adopted specific information on statistical analysis procedures.
The changes are incorporated in the documents currently available on the VOHC web site.
Vetradent Dog Chews, manufactured by Vetradent Inc. awarded the VOHC Seal of Acceptance for Plaque and Tartar.
Feline Greenies, manufactured by S&M Nu-Tec, Inc, awarded the VOHC Seal of Acceptance for Tartar.

Today is the start of National Pet Dental Health Month in North America (NPDHM), and to help celebrate this important yearly milestone in the oral and general health of North American companion animals, VOHC launched its revised and updated web-site, which now includes consumer information on periodontal disease in cats and dogs. To find out more about National Pet Dental Health Month, click NPDHM.
Additions to the list of Organizations Recognizing VOHC
VOHC is also celebrating the recent addition of the American Veterinary Dental Society and the Academy of Veterinary Dentistry to the list of dental organizations that endorse the VOHC Seal of Acceptance system. The VOHC Seal system is now recognized on four continents (Asia, Australasia, Europe and North America). For a full list of the organizations who are on-board with VOHC, click World-Wide.
Changes in Council
Two Members rotate off: Two dental scientists who were critical in establishing the Veterinary Oral Health Council in 1997 and were original members of the Council have rotated off the Council.
Drs. John Hefferren and George Stookey brought to the VOHC discussions and decisions many years of experience in efficacy recognition from the human dental arena. The immense contributions that Drs. Hefferren and Stookey made in building credibility and avoiding pot-holes in VOHC's early years are very much appreciated by VOHC Director Colin Harvey and by the Board of Directors of the American Veterinary Dental College, which administers the VOHC.
Changes in Protocols and Fees
The revised web site contains an enlarged and updated series of documents on VOHC protocols and submission procedures for companies marketing products that may qualify to carry the VOHC Seal of Acceptance.
In addition to web site changes designed to make the VOHC protocols and related requirements clearer and easier to access, some changes in content have been made in the VOHC protocols:
