本研究之目的,為瞭解台南市學齡前兒童的齲齒狀況。資料收集採分層兩階段集束抽樣法之抽樣調查設計,對台南市立案幼稚園、托兒所幼童,年齡2~6歲進行抽樣,共有幼童906人接受調查,完成率90.6%。研究結果顯示乳牙齲齒盛行率平均76.1%, def指數平均4.7顆,填補率15.7% '三歲到五歲間是學齡前幼童齲齒增加的關鍵期,而填補率於此年齡間並無明顯變化。齲齒型態的分佈幼小兒童以無齲齒型、小窩裂溝型及唇舌面型佔多數, 隨年齡增加,唇舌面伴隨臼齒鄰接面型比例偏高。奶瓶性齲齒盛行率,依國際間不同診斷定義為15.8%~44.5% ,五個年齡組幼童乳齒齲蝕機率,皆以下顎第二乳臼齒最高,六足歲幼童恆牙第一大臼齒萌發率40.0% 齲齒盛行率12.1% ,填補率皆為零。
The aim of this research is to understand the caries status of the preschool children in Tainan City and to provide the information for authorities to develop programs on the caries prevention and proper oral hygiene for the preschool children. A stratified two stages cluster sampling with PPS design was adopted for all day-care centers and kindergartens in Tainan City, aged 2-6 years. There were 906 children receiving the oral examinations and questionnaires. The response rate was 90.6%.The results revealed that the caries prevalence was 76.1 %, the mean def index was 4.7, and the filling rate was 15.7%. The caries prevalence was dramatically increased between 3 and 5 years old, but the filling rate was not changed significantly. The distribution of caries patterns was different among age groups. The caries-free pattern, pit and fissure caries pattern and labial-lingual caries pattern were dominant in the younger age groups. With increasing age, the labial-lingual plus molar proximal caries pattern was dominant. The prevalence of nursing caries was between 15.8%~44.5%. The mandibular second deciduous molars were the most susceptible to caries in the primary dentition. The eruption rate, caries prevalence and filling rate of the permanent first molars in the 6 years old children were 40.0%, 12.1 %, and 0.0% respectively.
