To assess plaque, caries, and oral hygiene habits amongst patients receiving fixed-orthodontic treatment at the Dental-Clinic, Universidad-El-Bosque, Bogotá, Colombia.
Test-group: 74 12-29-year-olds receiving fixed-orthodontic treatment; reference-group: 63 12-29-year-olds before they started the orthodontic treatment. Visual examinations (one examiner) recorded the following: Ortho-plaque-Index (OPI) expressed per patient as good, fair and poor-oral-hygiene. Caries was scored with the modified-ICDAS-II criteria as: 0-sound; 1B/1W-brown/white-opacity-after-air-drying; 2B/2W-brown/white-opacity-without-air-drying; 3-microcavity; 4-underlying-shadow; 5/6-distinct/extensive-cavity. Filled/missing surfaces due-to-caries and caries-lesions on buccal surfaces at three sites around the brackets were recorded. A 7-item self-administered oral-hygiene habits' questionnaire was used.
Chi-square test revealed that the oral-hygiene level was significantly better in the reference group compared to the test group (p < 0.05). The traditional mean DMF-S was 6.7 +/- 6.3 in the test- and 6.2 +/- 5.9 in the reference-group (p > 0.05). When adding modified-ICDAS-II lesions scores 1-4, the figure increased to 23.6 +/- 9.4 in the test- and to 13.6 +/- 10.3 in the reference-group (p < 0.001). A total of 96% had > or = 1 white-opacity in the test group versus 56% in the reference group (P < 0.001). In the test-group the buccal-surfaces accounted for most white-opacities and close to 1/3 of these lesions on the upper-anterior teeth were located around the brackets. The questionnaire disclosed that 58% in the test- vs. 44% in the reference-group did not accept having dental caries lesions during the orthodontic treatment.
The results showed a high prevalence of white-opacities related to orthodontic appliances and indicate the need to implement preventive programmes at the dental clinic.
评估在哥伦比亚波哥大的埃尔博斯克大学牙科诊所接受固定正畸治疗的患者的牙菌斑、龋齿及口腔卫生习惯。
试验组：74名年龄在12至29岁之间接受固定正畸治疗的患者；对照组：63名年龄在12至29岁之间且尚未开始正畸治疗的患者。由一名检查者进行视觉检查并记录以下内容：正畸牙菌斑指数（OPI），以每位患者的口腔卫生状况分为良好、一般和较差。龋齿采用改良的ICDAS-II标准评分：0 - 完好；1B/1W - 气干后呈棕色/白色不透明；2B/2W - 未气干时呈棕色/白色不透明；3 - 微龋洞；4 - 潜在暗影；5/6 - 明显/广泛龋洞。记录因龋齿导致的充填/缺失牙面以及托槽周围三个部位颊面的龋损情况。使用一份包含7个项目的自我管理口腔卫生习惯问卷。
卡方检验显示，对照组的口腔卫生水平显著优于试验组（p < 0.05）。试验组的传统平均DMF - S为6.7±6.3，对照组为6.2±5.9（p > 0.05）。当加上改良ICDAS - II标准中1 - 4级病损评分时，试验组该数值增至23.6±9.4，对照组为13.6±10.3（p < 0.001）。试验组共有96%的患者有≥1处白色不透明，而对照组为56%（P < 0.001）。在试验组中，颊面的白色不透明情况最为常见，且上前牙上近1/3的此类病损位于托槽周围。问卷显示，试验组中有58%的患者与对照组中44%的患者不承认在正畸治疗期间患有龋损。
结果表明与正畸矫治器相关的白色不透明情况普遍存在，提示牙科诊所需要实施预防方案。
