116 Chapter 5 Patients with a tumor in the ‘maxillary complex’ were at risk of receiving a radiation dose of ≥40Gy for all maxillary teeth and ipsilateral mandibular molars. The percentage of redundantly removed teeth in this group was 60% for Dmean and 49% for Dmax (Table 2 and Supplementary Table 2F1-2F2). In the nasopharyngeal group, the only jaw regions that ultimately received a dose of ≥40Gy were the molar regions in the maxilla and ipsilateral mandible and the second premolar on the contralateral side of the mandible. This resulted in a percentage of redundantly extracted maxillary teeth of 76% for Dmean and 61% for Dmax. For mandibular teeth the percentages were 95% for Dmean and 87% for Dmax (Supplementary Tables 2G1-2G2). All but one of the 25 patients from group “other” consisted of skin tumors located in the face, scalp and or neck region, treated with radiation. The percentage of redundantly removed teeth ranged from 84% for the Dmean to 72% for the Dmax (Table 2 and Supplementary Tables 2H1-2H2).
