Problem statement: There are indications that appropriate chew treats can contribute to the control of canine periodontal disease. It was reasoned that the incorporation of a cellulose fiber network into the treat may improve the efficacy, but for proof experimental data were required. Approach: A double-blind, placebo-controlled trial with privately owned dogs was carried out to assess the efficacy of a cellulose preparation (Arbocel BWW40®) in the treatment of periodontal disease. With the use of a questionnaire, the clinical signs were evaluated by the owners. There were 10 clinical signs: extent and severity of dental plaque and calculus, extent of gingivitis, redness, swelling, bleeding and firmness of gingivae and halitosis. For a period of 8 weeks, the test dogs daily received a chew treat to which 4% of the cellulose preparation was added. The control dogs were given a chew treat with identical formula, but without added cellulose. During the trial, all dogs were fed the same, complete dry food. There were 16 test dogs and 15 control dogs. Results: When compared with the baseline values, the administration of the test chew significantly improved 8 out of the 10 clinical signs. In the placebo group there was a significant improvement for 6 clinical signs. When the improvements over time for the two groups were compared, there were no statistically significant differences. When the score changes for all 10 clinical signs were added up as an overall index of improvement of periodontal disease, the test group showed a 17% greater amelioration than did the control group. Conclusion: The addition of the cellulose preparation had further enhanced the efficacy of the treat, possibly through an increase in mechanical cleansing and chewing time. This study indicates that a cellulose-containing treat is beneficial for dogs with periodontal disease and it is suggested that it may also impair its development.
