Pretherapy dental status of patients with malignant conditions of the head and neck.

Maxillofacial problems after radiotherapy to this region are common and have at least a temporal relationship to preexisting odontogenic disease. This study was undertaken to determine the dental status of patients before multimodality therapy for head and neck cancer. One hundred thirty-one patients were examined during their initial visit to a head and neck tumor clinic. The majority of dentulous patients were noncompliant with routine dental care (76%) and oral hygiene (65%). There was a high incidence of alveolar bone loss (66%), clinical caries (71%), and failing restorations (91%). Overall, 73 (97%) of the dentulous patients needed dental care before radiotherapy; however, follow-up visits revealed that 59 (81%) of these patients did not seek the indicated treatment. These data suggest that thorough oral examinations should be performed on all patients before radiotherapy that involves the oral cavity.
