- Objectives: The Kungsholmen Elders Oral Health Study (KEOHS) evaluated the oral health status of generally healthy, community-dwelling persons over the age of 80 living in Kungsholmen, Sweden. This paper explored possible clinical risk indicators of coronal and root caries among the KEOHS subjects.Design: In this cross-sectional study, dentate KEOHS subjects received a caries assessment using defined visual, tactile criteria.Setting: Examinations were carried out in two local clinics by standardized examiners.Subjects: One hundred twenty-nine dentate persons were examined.Main Outcome Measures: The examination identified decayed and filled surfaces, prosthetic crowns, and missing teeth.Results: More root than coronal surfaces had untreated decay, and secondary root caries contributed the greatest number of decayed surfaces. Ninety percent of the examined dentate subjects had at least one prosthetic crown. Root surfaces exposed to crown margins were more likely to have caries than root surfaces not so exposed, particularly among women. The presence of untreated coronal caries (yes/no) was positively associated with having untreated root caries and an intermediate number (14–20) of teeth, but inversely associated with having 4+ prosthetic crowns. Active root caries (yes/no) was positively associated with having untreated coronal caries, 14–20 teeth, and 4+ prosthetic crowns. Nearly 20% of ident2ified root lesions were present at or below the gingival margin, and most (88%) were secondary caries associated with crown margins (65%) or other restorations (23%).Conclusions: Our findings suggest that some dental characteristics, including the presence of prosthetic crowns, are risk indicators for the presence of untreated coronal and root caries.
