In an attempt to determine the association between overall health status, medication history, and oral hygiene status and root caries, 24 older persons residing independently in the community and 23 residents of a nursing home were interviewed and received oral examinations, using the Oral Hygiene Index and the Root Caries Index. The mean age of this population was 80 yr, with the nursing home subjects somewhat older than community-dwelling subjects. Only six persons had no root surface caries; three subjects had caries on all tooth surfaces with gingival recession. Mandibular teeth, particularly molars and premolars, showed the greatest attack rate. The best predictors of root caries were number of teeth remaining, calculus, plaque, and the use of medications with xerostomic effects. Medications were most predictive of maxillary root caries. The results point to the need to provide interceptive dental therapeutics for high risk geriatric populations such as those using multiple medications and with a poor history of oral care.
为了确定总体健康状况、用药史、口腔卫生状况与根龋之间的关联，对24名独立居住在社区的老年人和23名养老院居民进行了访谈，并使用口腔卫生指数和根龋指数对他们进行了口腔检查。该人群的平均年龄为80岁，养老院受试者比社区居住受试者年龄稍大。只有6人没有根面龋；3名受试者所有有牙龈退缩的牙面都有龋坏。下颌牙，尤其是磨牙和前磨牙，龋患率最高。根龋的最佳预测因素是余留牙数量、牙石、牙菌斑以及使用具有口干效应的药物。药物使用对上颌根龋的预测性最强。结果表明，有必要为高危老年人群，如使用多种药物且口腔护理史较差的人群，提供预防性牙科治疗。
