Twelve patients underwent adjuvant head and neck radiotherapy. Cold sensitivity pulp testing and/or electric pulp testing were performed on teeth at the margin of mandibulectomy and on teeth adjacent to mandibulotomy after surgery. A“positive” response was considered the healthy state, and “negative” was considered the diseased state of the tooth. Results The 10 patients who underwent mandibulotomy had 12 teeth with a negative response. The 4 patients treated by mandibulectomy had two positive and three negative responses to cold and electric pulp tests. Fifteen out of 23 teeth (65 . 2%) showed a negative response to sensitivity testing.  \nConclusions Tooth necrosis seems to be a common event after mandibulectomy and mandibulotomy.  \nClinical Relevance To avoid post-surgery complications, performing root canal therapy before surgery on the teeth adjacent to the surgical site could be an appropriate strategy.  \nKeywords Head and Neck Cancer, Oral Cancer, Mandibulotomy, Mandibulectomy, Tooth prognosis, Tooth survival  \n†Raffaella Castagnola and Cosimo Rupe contributed equally to this work.  \n*Correspondence: Cosimo Rupe [cosimorupe@gmail.com](cosimorupe@gmail.com)  \n1Head and Neck Department, School of Dentistry, Fondazione Policlinico Universitario A.
