齲齒 (Dental Caries) 是口腔內細菌利用飲食殘留之醣類作為繁殖的養分，分解產生酸，進而使牙齒表面的琺瑯質產生脫鈣腐蝕的現象，亦即牙齒表面的一種進行性的去礦化現象，俗稱「蛀牙」。塗氟是使用適量局部性的氟化物讓牙齒表面吸收，達到預防齲齒的效果，而現代醫學研究證實塗氟可以降低乳齒齲齒率達33%、恆齒齲齒率46%。
本研究以新北市某牙科診所103~105年的病歷資料庫，針對0~12歲齲齒兒童以塗氟、溝隙封填及塗氟與溝隙封填並用等方式治療及治療期間藥物之併用探討齲齒治療效果之回溯性分析，以SPSS /12.0 統計軟體研究變項描述性統計分析、卡方檢定、獨立/成對樣本T檢定及ANOVA執行資料檢定分析。
研究結果顯示，596位受診0~12歲齲齒兒童中以新莊區患者居多，女童齲齒患者比男童多，4歲齲齒兒童佔多數 (13%)，由168人接受塗氟及溝隙封填預防治療之4~9歲齲齒兒童中，使用塗氟者為最多，佔59%，顯示齲齒兒童以使用塗氟為主要預防蛀牙之方法。另外，將使用塗氟病患區分為持續性及間歇性使用塗氟，持續性使用者在統計學上有顯著之差異，可以使治療前3.18顆蛀牙持續治療後降至1.36顆，顯示持續性使用塗氟更能有效預防蛀牙。 Dental caries commonly known as tooth decay is a phenomenon of tooth corrosion that oral bacteria produce acid by using carbohydrate which were left in eating as nutrients. Fluoride varnish can reach the goal of preventing tooth decay when smearing suitable fluoride in the tooth surface. A number of reasons may account for these divergent findings that dental caries rate of milk teeth has decreased 33% and rate of permanent teeth has decreased 46%.
This study aims to analyze the effects of preventing tooth decay that using fluoride varnish and fissure seal with medicine combined in early childhood caries 0-12 years of age with the database from one of the dentistry clinic in New Taipei City during the year of 103 to 105. Statistical analysis was calculated by using SPSS/12.0 for chi-square, Independent-Samples T Test, Paired-Samples T Test and One-Way ANOVA.
Female patients are more than male patients in a total of 596 subjects, and there were most in 4 years of age (13%). In addition, the prime place of residence is Xinzhuang Dist. The proportion of fluoride varnish was significantly numerous in a total of 168 subjects (59%) who take the medical treatment of prevention at aged 4-9. The study found that fluoride varnish was the prime way to prevent tooth decay. Whereas dental caries rate was significantly different in subjects with fluoride varnish continuously, and was not significantly different in subjects with fluoride varnish intermittently. It could decrease in the count of tooth decay from 3.18 to 1.36. The study found that using fluoride varnish continuously can prevent tooth decay effectively.
