Abstract : 「緒言」 近年, 日本人の現在歯数は増加傾向にあり, 4mm以上の歯周ポケットを有する者の割合も増加している. 平成29年版高齢社会白書によると日本の高齢化率は27.3%であり, 今後も増加が予測される. つまり, 日本ではさらなる高齢化とともに歯根露出も増えることが予想され, 根面う蝕の増加が懸念される. 事実, 平成28年歯科疾患実態調査結果では, 高齢者のう蝕を持つ割合は増加しており, この中には根面う蝕の有病者が含まれていることが推測される. 日本における根面う蝕の有病状況の実態報告は, 高齢者を対象としたものがほとんどである. 65歳以上の有歯顎者465名を対象とした調査において, 活動性根面う蝕の有病者率は30.3%であった. 60~94歳までの健常者161名を対象とした調査では, 活動性根面う蝕(着色した軟化歯質のある実質欠損), 非活動性根面う蝕(表面に実質欠損および着色はあるが軟化した歯質が認められないもの)および処置済み根面を合わせた根面う蝕経験者率は28.6%, 活動性根面う蝕有病者率は13.7%であった.

Abstract : [Abstract] Limited information is available regarding root caries in Japanese workers. Therefore, this study evaluated the prevalence of root caries and related factors in Japanese workers. Participants were 300 workers (71.7% men) aged 30-69 years who completed a questionnaire about their health behavior and general health condition, and underwent a dental examination. Root caries of the front teeth were diagnosed by calibrated dentists, and active root caries, inactive root caries, and root fillings were regarded as root caries experience. Decayed, missing, and filled coronal teeth (DMFT) values in the full mouth and papillary marginal attached (PMA) index scores were also calculated. After adjusting for sex and age, logistic regression models were used to determine the association between the presence/absence of root caries experience or active root caries (outcome variable) and each of the following explanatory variables: smoking, consumption of sugary foods and beverages, toothbrushing frequency, use of fluoride toothpaste, systemic disease related to decreased salivary secretion, DMFT, and PMA index. The prevalences of root caries experience and active root caries were 15.7% and 1.6%, respectively. Non-use of fluoride toothpaste (odds ratio [OR]=2.50; 95% confidence interval [CI]: 1.25-4.99) and DMFT (OR=1.10; 95% CI: 1.03-1.17) were significantly associated with root caries experience. Frequent consumption of carbonated beverages (OR=8.09; 95% CI: 1.25-52.3), having systemic disease (OR=8.70; 95% CI: 1.08-70.3), and DMFT (OR=1.24; 95% CI: 1.03-1.48) were significantly associated with active root caries. These results suggest that non-use of fluoride toothpaste, frequent consumption of carbonated beverages, having systemic disease related to decreased salivary secretion, and high DMFT are risk factors for root caries in Japanese workers.
