title: Oral hygiene and root caries occurrence in Slovenian adults.
abstract: This study investigated root caries related findings made in connection with basic clinical dental routines. A total of 410 adults, mean age 42.8 years, seeking dental care in two Slovenian communities, rural Ravne and urban Ljubljana, during a three-month period, were clinically examined for root caries. Primary root caries was defined as a softened yellowish-brown lesion gently penetrable by an explorer and situated principally on a root surface. Past root caries was defined as fillings at a similar location. A subject's oral hygiene was judged clinically as good, fair or poor, based on presence of dental plaque and subgingival calculus. Subjects' background variables included age, gender, and number of teeth. Subjects had on average 23.1 teeth, from which 0.8 teeth had primary root caries and 0.4 had fillings on root surfaces. Primary root caries occurred in 42 per cent of subjects, in 38 per cent of men and 45 per cent of women (P = 0.21), but fillings on root surfaces in only 19 per cent of the subjects, 11 per cent of men and 25 per cent of women (P = 0.001). The strongest factors explaining the presence of root caries, with control for other factors, were poor oral hygiene (odds ratio 3.1), smaller number of teeth (odds ratio 2.3 to 2.7), and older age (odds ratio 2.1). In conclusion, in everyday clinical dental practice, more emphasis should be placed on patients' proper oral hygiene and their encouragement and motivation to achieve it.
