| pubmed-article:20189430 | pubmed:abstractText | Pre-irradiation dental care depends on teeth health, fields and dose of irradiation, compliance to fluorides, cessation of tobacco and psychosocial cofactors. Dental care aims at preventing complications and preserving the quality of life (eating, speech and aesthetics). Approximately 11% of patients do not require any pre-irradiation dental care. Dental complications vary from slight colorations of the teeth to major complication such as osteoradionecrosis. Osteoradionecrosis rates vary from 1 to 9%, and may be decreased by using a 21-day delay between extractions and irradiation, provided that it does not postpone cancer treatment, with a dose-dependent risk (<6% if <40 Gy; 14% between 40 et 60 Gy; > or =20% if >60 Gy). Osteoradionecrosis occurs spontaneously (35%), mostly involves the mandibula (85%). | lld:pubmed |
