     The formidable canines of adult macaques are a great concern for the biomedical research community for their ability to inflict severe injury on conspecifics, self, and the human care staff. Various procedures from blunting, to cutting (vital pulpotomy), to extraction have been used to deal with this concern. All three procedures have inherent advantages and disadvantages. The data from 155 adult male macaques (Macaca mulatta & M. fascicularis) that were blunted at Panther Tracks Learning Center (PTLC) since 2002 were investigated. The blunting procedure employed requires the rounding of the tip of the canine. The canines were repeat blunted during semi-annual exams due to supraeruption and the honing surface on the premolars, which re-sharpens the canines during mastication. The macaque canines were blunted a mean of 3.3 times (range 1- 6 blunts) over a 3 year period. None of the 155 animals (n= 33 rhesus; n= 122 cynomologus) that were blunted developed an infection leading to an abscess due to blunting. The supposition that blunting macaque canines increases the risk of infection and therefore abscess is not supported. The few reported cases of abscess are more likely due to technician error than technique error. Blunting can be a safe and rapid procedure that requires minimal labor and can be easily included during facilities’ semi-annual exams.
