某病院小児歯科で歯科健診を受けた1歳児1,529人を対象として, 健診結果と健診時の保護者の相談内容について集計した。その結果, 以下の結論を得た。

1. 萌出歯数は1歳0か月では7.5本, 1歳6か月では13.8本であった。

2. 齲蝕に罹患していた小児の割合は3.6%であった。また, 1歳0か月～1歳5か月までの3.2%, 1歳6か月～1歳11か月までの10.7%の小児が齲蝕に罹患していた。

3. 齲蝕に罹患した小児のうち, 85.5%が卒乳していなかった。また, 61.8%に就寝前または夜間の母乳の摂取, 29.1%に哺乳瓶による就寝前または夜間の飲料の摂取の習慣があった。

4. 1歳児を持つ保護者への「何か気がかりなことはありますか」という質問に対し, 最も多かった回答は「歯みがきを嫌がる」であり, 以下順に「歯ならび」, 「歯みがきの方法」であった。

5. 歯科健診を受けた1歳の小児のうち, 43.0%が健診を契機に引き続き同病院小児歯科を定期的に受診するようになった。そのうち, 健診をした時点で齲蝕に罹患していたのは4.4%であった。また, 定期的に受診するようになった小児の保護者のうち, 44.4%が歯科健診時に「特に気になることはないという回答をしていた。このことから, 齲蝕治療などの特別な動機がなくても, 1歳時の歯科健診を契機に定期的に小児歯科を受診するようになる小児が多く存在することが判明した。

The results of dental examinations and the contents of consultation with parents or guardians at the time of examination were compiled for 1,529 1-year-old infants without having any particular motivation who received dental examinations. The results of this study were as follows:

1. The mean number of erupted teeth in infants aged 1year and 0 months was 7.5.

2. Dental caries affected 3.2% of the infants aged 1year and 0 to 5 months and 10.5% of the infants aged 1year and 6 to 11 months.

3. Among the infants afflicted with caries, 85.7% had not been weaned. 61.8% were generally breast-fed before going to bed or during the night, and 29.1% were bottle-fed before going to bed or during the night.

4. When parents with 1-year-old infants were asked if they felt anxious about their children's oral health, the most common response was "aversion to teeth-brushing", followed by "teeth alignment" and "methods of brushing their children's teeth".

5. Of the infants who received dental examinations at age 1, 43.0% continued to receive regular pediatric dental care. Among those infants who become regular patients, only 4.4% were afflicted with caries in examinations at age 1. Moreover, 44.4% of the parents of infants who came to receive regular care had answered at the dental examination that they had "no particular anxieties". Thus it was clear that even without caries or a particular motivation, there are many infants who come to receive regular pediatric dental care due to the approach of the dentist.
