Evaluación del extracto de caléndula (Caléndula officinalis) como terapia alternativa en la enfermedad periodontal en caninos (Canis lupus familiaris)

Abstract

The objective of the present experimental work was to evaluate the therapeutic effect of marigold extract as a 10% infusion as an alternative therapy in periodontal disease in dogs, due to its anti-inflammatory, antiseptic and antibacterial actions. Two treatments of calendula extract were applied by means of posology (once a day and twice a day) in comparison with chlorhexidine 0.02% and distilled water in 32 dogs, in which gingival indexes, dental calculus, dental mobility and furcation exposure were identified by means of a periodontogram as a dental control card, thus obtaining results of slight inflammation and presence of fine and visible dental calculus. For statistical differentiation, the Pearson Chi-Square test was applied to correlate the degrees of each index with the treatments at 20 days, which was significant (p<0.05) in gingival index and dental calculus index and not significant (p>0.05) in dental calculus index and furcation exposure. All the dogs were divided into treatment groups, 8 patients for calendula extract once a day (T1), 8 with calendula extract twice a day (T2), 8 with chlorhexidine 0.02% (T3) and 8 with distilled water (T4), dental cleaning was done and then they were treated for 20 continuous days. The therapeutic effect was evidenced by the samples taken before and after treatment by means of CFU count. At the end of the experiment, signs of mild inflammation to normal gingiva and fine to absent dental calculus decreased. In the CFU count, T2 reduced 92.4% of microbiological colonies, which when compared with T1, T3 and T4 there is a significant difference because they act in different ways and present means in treatments where the marigold extract and chlorhexidine are more effective. Based on Tukey's test at 95%, which showed non-significant results between T1, T2 and T3 (p>0.05) and significant in T4 (p<0.05), ANOVA showed significant results (p<0.0001) in CFU reduction. Key words: Calendula, periodontogram, CFU, periodontal disease, chlorhexidine, distilled water.
