The New England Elders Dental Study (NEEDS) reports the prevalence, extent and severity of oral diseases and conditions among a representative sample of community-dwelling elders age 70 and older residing throughout the six New England states. In-home, full-mouth examinations were conducted by four calibrated dentists who used National Institute of Dental Research (NIDR) standardized disease measures plus additional diagnostic codes on all tooth surfaces. Only 37.6% of elders age 70 and older were edentulous, while dentate elders had a mean number of teeth per person ranging from 21.5 to 17.9 across age and gender cohorts. The prevalence of untreated coronal decay in elders with teeth was 28% in female elders and 34% in male elders. More than 90% of all elders with teeth had coronal fillings and 22% exhibited untreated root caries. Periodontal destruction was substantial, with 66% of dentate elders exhibiting moderate periodontal pockets (4–6 mm) while 21% exhibited severe periodontal pocketing (>6 mm). Comparisons with national surveys suggest that periodontal disease prevalence and severity appear to have been underestimated in previous national studies of the elderly. Because of aging and tooth retention trends, the periodontal disease problem of the elderly may be increasing in the face of dentists' tendency to underdiagnose the periodontal diseases, legal constraints on dental hygienists to independently treat them, and inadequate funding for conservative nonsurgical therapies.
