fa Effect of 1.23% Acidulated Phosphate Fluoride Foam on White Spot Lesions in Ortho- dontic Patients: A Randomized Trial کودکان Pediatric Dentistry پژوهشي Research <p> <strong>Purpose:</strong></p><p>  The decalcification of enamel is a serious clinical problem in orthodontic patients and is usually observed as white spot lesions surrounding brackets. This study's purpose was to evaluate the effect of professionally applied 1.23 percent fluoride foam on reducing the formation of white spot lesions (WSLs) in patients with fixed orthodontic appliances. </p><p> <strong>Methods:</strong></p><p>  In a randomized, double-blind, placebo-controlled trial, 100 participants were randomly divided into two groups. The two groups received fluoride foam and placebo foam, respectively, every two months during the treatment. The examinations before bonding and after debonding were performed by one examiner and included the presence and severity of WSLs on incisors, canines, and premolars. </p><p> <strong>Results:</strong></p><p>  The incidence of WSLs was approximately 13 percent in the fluoride foam group and 51 percent in the placebo group (P<.001). The mean increment of WSLs score was significantly lower in the fluoride foam group (0.71±2.80) than in the placebo group (4.36±5.41 P<.001). The preventive fraction was approximately 76 percent, and the number needed to treat was calculated as 2.6.</p><p> <strong> Conclusions</strong>:</p><p>  Professional application of 1.23 percent fluoride foam during orthodontic treatment effectively reduced the development of white spot lesions. A prophylactic regimen based on the routine use of fluoride foam during orthodontic treatment is recommended. </p><hr><p></p><p> <strong>Source: </strong>Journal of American Academy of ‍ Pediatric Dentistry</p><p><a href="http://www.ingentaconnect.com/content/aapd/pd/2013/00000035/00000003/art00012" target="_blank"><font color="#0000ff"> Full Text</font></a></p> ACIDULATED PHOSPHATE FLUORIDE; CLINICAL TRIALS; ORTHODONTICS; PREVENTIVE DENTISTRY 0 0 http://idai.ir/browse.php?a_code=A-10-32-2564&slc_lang=fa&sid=1 Han Jiang 100319475328460012143 100319475328460012143 No Department of Preventive Dentistry, School and Hospital of Stomatology, Wuhan University, Wuhan City, Hubei Province, China Fang Hua 100319475328460012144 100319475328460012144 No Department of Orthodontics, School and Hospital of Stomatology, Wuhan University, Wuhan City, Hubei Province, China Liping Yao 100319475328460012145 100319475328460012145 No Department of Preventive Dentistry, School and Hospital of Stomatology, Wuhan University, Wuhan City, Hubei Province, China Baojun Tai taibaojun@126.com 100319475328460012146 100319475328460012146 Yes Key Laboratory of Oral Biomedicine Ministry of Education, School and Hospital of Stomatology, Wuhan University, Wuhan City, Hubei Province, China Minquan Tu 100319475328460012147 100319475328460012147 No Key Laboratory of Oral Biomedicine Ministry of Education, School and Hospital of Stomatology, Wuhan University, Wuhan City, Hubei Province, China
