DutraAbstractPeriodontitis and excessive tooth wear are considered two of the most important oral diseases affecting the health, performance, and welfare of small ruminants. The present study aimed to describe the occurrence of periodontitis and excessive wear of the incisor and masticatory teeth among a herd of dairy goats, the presence of possible risk factors, and the presence of microorganisms considered potential periodontal pathogens. For this, 150 dairy goats of the Saanen and Pardo Alpina breeds with different periodontal conditions and aged 13 months to 8 years were clinically examined. Animals were fed a commercial ration specific for each age group and supplied at will bulky hay composed of Tifton grass hay (Cynodon nlemfuensis) or massai (Panicum hybrid vr. Massai) and corn silage. Scores from 0 to 3 were initially attributed to the presence and intensity of gingival recession, presence of supragingival biofilm, and wear of the dental crown. The presence of 23 microorganisms considered, as potential pathogens was evaluated by polymerase chain reaction (PCR) from subgingival biofilm samples obtained from periodontal pockets with clinical probing depth of ≥5 mm (n = 22) and the gingival sulcus of periodontally healthy animals (n ...
