The purpose of this study was to evaluate changes in the periodontium in patients who received head and neck radiation therapy.
Periodontal clinical parameters (probing depth, clinical attachment level, gingival recession, plaque index, and bleeding on probing) were assessed on 27 patients before and 6 to 8 months following radiation therapy in the head and neck area.
The greatest changes occurred in clinical attachment level: overall, 70.3% of the patients showed a loss, with 92% evincing loss in the mandible. Attachment loss was directly related to the field of radiation and was greater when the jaws were actually included in the irradiated area.
Periodontal status should be evaluated prior to and following radiation therapy in the oral-maxillary-facial region to help ensure that periodontal health is maintained in oncology patients.
本研究的目的是评估接受头颈部放射治疗患者的牙周组织变化。
对27例患者在头颈部放射治疗前以及放疗后6至8个月评估牙周临床参数（探诊深度、临床附着水平、牙龈退缩、菌斑指数和探诊出血）。
临床附着水平变化最大：总体而言，70.3%的患者出现附着丧失，下颌骨附着丧失的患者比例为92%。附着丧失与放射野直接相关，当颌骨实际包含在照射区域时附着丧失更严重。
在口腔颌面区域进行放射治疗之前和之后，均应评估牙周状况，以帮助确保肿瘤患者维持牙周健康。
