A study is made of the dental implications of oral cancer, with a view to avoiding the complications that appear once oncological treatment is started.
The study comprised a total of 22 patients diagnosed with oral cancer according to clinical and histological criteria in the Service of Maxillofacial Surgery (Dental Clinic of the University of Barcelona, Spain) during the period 1996-2005, and posteriorly treated in different hospital centers in Barcelona.
Of the 22 patients diagnosed with oral cancer in our Service, the present study finally analyzed the 12 subjects who reported for the dental controls. As regards the remaining 10 patients, 5 had died and 5 could not be located; these subjects were thus excluded from the analysis. All of the smokers had abandoned the habit. The most common tumor location was the lateral margin of the tongue. None of the patients visited the dentist regularly before the diagnosis of oral cancer. T1N0M0 was the most common tumor stage. Surgery was carried out in 50% of the cases, while 8.4% of the patients received radiotherapy and 41.6% underwent surgery with postoperative radiotherapy. In turn, 66.6% of the patients reported treatment sequelae such as dysgeusia, xerostomia or speech difficulties, and one patient suffered osteoradionecrosis. Forty-one percent of the patients did not undergo regular dental controls after cancer treatment. As regards oral and dental health, 16.6% presented caries, and 50% had active periodontal disease.
Protocols are available for preventing the complications of oral cancer treatment, and thus for improving patient quality of life. However, important shortcomings in the application of such protocols on the part of the public health authorities make it difficult to reach these objectives.
研究口腔癌的牙科影响，以避免在开始肿瘤治疗后出现并发症。
本研究共纳入 22 例经临床和组织学标准诊断为口腔癌的患者，这些患者于 1996 年至 2005 年期间在西班牙巴塞罗那大学颌面外科服务部（巴塞罗那大学牙科诊所）就诊，随后在巴塞罗那的不同医院中心接受治疗。
在我们的服务中诊断出的 22 例口腔癌患者中，本研究最终分析了前来进行牙科检查的 12 名患者。对于其余的 10 名患者，5 人死亡，5 人无法联系，因此将这些患者排除在分析之外。所有吸烟者均已戒烟。最常见的肿瘤部位是舌侧缘。在诊断口腔癌之前，没有患者定期看牙医。T1N0M0 是最常见的肿瘤分期。50%的病例接受了手术，8.4%的患者接受了放疗，41.6%的患者接受了术后放疗。66.6%的患者报告有治疗后遗症，如味觉障碍、口干或言语困难，1 例患者患有放射性骨坏死。41%的患者在癌症治疗后未进行定期牙科检查。在口腔和牙齿健康方面，16.6%的患者有龋齿，50%的患者有活动性牙周病。
已经有预防口腔癌治疗并发症的方案，从而提高患者的生活质量。然而，公共卫生当局在应用这些方案方面存在重要的不足，这使得难以实现这些目标。
