Follow-up Study on Oral and Systemic Health in Elderly

从2009年到2011年，对1998年至2008年接受调查的老年人进行了为期3年的随访。如有必要，对每个受试者或其家属进行了包括死亡原因在内的病史访谈，并每年进行一次口腔健康和身体健康检查。结果表明：1)骨代谢指标影响牙周病的进展和骨密度的降低，并影响与骨硬度和牙齿脱落相关的下颌下皮层；2)低血清总胆固醇水平、低二十二碳六烯酸摄入量和低膳食饱和脂肪酸分别影响牙周病的进展；3)不吸烟的老年牙根龋患者发生心律失常的风险增加。4)较低的肾小球滤过率是心血管疾病发生和死亡的危险因素。

Elderly subjects surveyed between 1998 and 2008 were followed-up for 3 years from 2009 to 2011. Each subject or his/her family, if necessary, was interviewed about a medical history including cause of death, and received oral health and physical fitness examinations once a year. The results suggested that 1) bone metabolic markers influenced periodontal disease progression and decrease of bone mineral density, and also influenced mandibular inferior cortex related to bone stiffness and tooth loss, 2) a low total cholesterol serum level, low docosahexaenoic acid intake and dietary saturated fatty acids, respectively, influenced to periodontal disease progression, 3) non-smoking elderlies with root caries were at an elevated risk for dysrhythmias, and 4) low estimated glomerular filtration rate was a risk for cardiovascular disease occurrence and also for mortality.
