Patients with penicillin allergy who received other antibiotics than those who used amoxicillin were found to have higher rates of dental implant failures, observed a recent analytical study.  The research conducted by a team led by Dr Zahra Bagheri, clinical assistant professor with the Ashman Department of Periodontology and Implant Dentistry at New York University (NYU) College of Dentistry, demonstrated that out of the 838 patients examined, 17.1% of patients who reported a penicillin allergy experienced a dental implant failure, compared to 8.4% of patients who did not report a penicillin allergy. The study, published in Clinical Implant Dentistry and Related Research, pointed out that the patients who received clindamycin, which was the most common alternative antibiotic, were at higher risk for implant failure.
