Establishing a targeted plan for prophylactic dental extractions in patients with laryngeal cancer receiving adjuvant radiotherapy

Abstract

Objective The purpose of this study was to determine dose delivered to individual mandibular tooth-bearing regions during adjuvant intensity-modulated radiotherapy for laryngeal cancers. Study Design Twenty patients with laryngeal cancer treated with intensity-modulated radiotherapy were included. Individual mandibular tooth-borne areas were manually contoured. Average doses were calculated for individual teeth. Results Doses to individual teeth increased with more posterior location. Highest dose was observed for third molar (M3) (43.1 Gy; P
