혀의 편평상피세포암과 보철물 위치의 상관성에 대한 임상연구

Abstract

1. Objectives Various risk factors of squamous cell carcinoma of tongue represent relatively high incidence in intraoral cancer. It is well known that smoking and drinking are major two risk factors. Gender, age and human papilloma virus infection are also attributable to tongue cancer. It has been reported that intraoral dental prosthesis could be related to squamous cell carcinoma of tongue, but controversy has been still reported. The purpose of this study is to investigate the relationship between the squamous cell carcinoma of tongue and dental prosthesis for positional aspects by retrospective analysis.

2. Methods Total 439 patients of squamous cell carcinoma of tongue were diagnosed and managed in the department of oral and maxillofacial surgery, Seoul national university dental hospital from first January, 2001 to thirtieth June, 2013 for 12.5 years. They were managed by four maxillofacial surgeons of oral cancer and reconstruction team in Seoul national university dental hospital. Among 439 patients, 211 patients were satisfied with several criteria, such as pathologic diagnosis as malignancy in tongue, clinical information about intraoral prosthesis, and panoramic radiograph to find the types and locations of prostheses obviously. These 211 patients were categorized by gender, age, position with type of prostheses and the main location of tongue malignancy. Statistical analysis was performed.

3. Results Of the squamous cell carcinoma of tongue patients, 80 patients (37.9%) were female and 131 (62.1%) were male. The mean age 54.9 years old, with fifties had the highest frequency (60 patients, 28.4%), and patients less than twenties were 11 (5.2%). There was significance between the patients with crown or bridge (134, 63.5%) and those without the prostheses (77, 36.5%). But, regardless of types of prostheses such as crown, bridge or denture, there was not significant difference between position of prostheses and location of squamous cell carcinoma of tongue since there were no p values less than 0.05 in Pearson-chi square test.
