TY - BOOK AU - Thompson, A. TI - Ability to deliver safe dental care and optimal prosthetic rehabilitation are correlating with irradiation doses in maxillary and mandible PY - 2016/// N1 - NMUH Staff Publications; 96 N2 - <span style="font-size: 10pt;">Purpose/Objective(s): Dental cares in irradiated areas required to knowdelivered dose in maxillary and mandible bones to avoid the risk of postirradiationcomplications and to adapt care proposals. We assume that toknow the sites of future implants before dosimetry validation and irradiationimprove the ability to fix implant and to do dental care aftertreatment.Materials/Methods: In 48 patients, the dentist suggested proposals ofdental rehabilitation but the radiation oncologist did not know these at timeof dosimetry validation. Maxillary and mandibula were delineated bysextants. From the literature dose data, four levels of risk of dental carescomplications and three levels of risk of implant failure were defined.According to the delivered doses we calculated the percentage of patientsthat can receive dental care at the different level of risk and the percentageof patients who can be fully rehabilitated with implant as proposed by thedentist before radiation beginning.Results: For the dental cares, according to the mean delivered doses, thenone, low, intermediate and high risk groups represents 49.3%, 37.2%,8.7% and 4.6%, respectively of the sextant of interest and 31.1%, 23.3%,20.1% and 25.6%, respectively, according to the maximal delivered dose.For the complete edentulous arches, a prosthetic implanted rehabilitationcan be performed, as proposed, at low risk in 76.5%, if mean delivereddose was considered and only 41% if maximal dose was the consideredvalue. For partial edentulous sextants, 60.7% can be implanted, as proposed,at low risk when mean dose was considered and 40.4% whenmaximal doses where considered.Conclusion: Knowing the sites of implantation before dosimetry validation,the radiation oncologist could shield some specified areas that couldimprove the possibilities of dental rehabilitation. The dialogue betweendentist and radiation oncologist could improve the possibilities of implantsand decrease the risk of unsafe dental care.</span> UR - http://www.redjournal.org/article/S0360-3016(16)31847-8/pdf ER -
