Visually impaired children are challenged everyday in their everyday skills. Oral hygiene practices among visually impaired children require a special approach with time and patience. The purpose of this study was to evaluate the effect of oral health education and fluoridated dentifrices on the oral health status of visually impaired children.
Fifty visually impaired children between 8 and 12 years of age formed the study group. Oral health education and motivation was done with the help of Braille. Modified Bass method of brushing was taught to the children and the required dental treatment was done. Subjects were randomly divided into two equal groups fluoridated and non-fluoridated. Oral hygiene index -simplified, DMFT, deft index, and Streptococcus mutans and Lactobacillus count were assessed at baseline, immediately after the treatment and at 3, 6, and 12 month intervals. The oral health awareness was assessed using a questionnaire at the beginning and end of the study.
At baseline, the mean OHI-S, DMFT and deft scores were 2.72, 0.47, and 0.51 respectively. At the end of 12 months there was a significant decrease in OHI-S scores in the fluoridated group. No significant difference was seen in DMFT and deft between the fluoridated and non-fluoridated groups at the different time interval. After the oral health education and comprehensive treatment there was a reduction in Streptococcus mutans and Lactobacillus counts in both groups; however, at the end of 3, 6, 12 months there was a significant decrease in fluoridated group as compared to the non-fluoridated. The oral health awareness increased significantly at the end of the study.
The oral health education and motivation formulated for the visually impaired children was effective in improving their oral health status. Fluoridated dentifrices decreased the Streptococcus mutans and Lactobacillus counts and improved the oral hygiene status.
视力受损儿童在日常技能方面每天都面临挑战。视力受损儿童的口腔卫生习惯需要特别的方法，需要时间和耐心。本研究的目的是评估口腔健康教育和含氟牙膏对视力受损儿童口腔健康状况的影响。
50名8至12岁的视力受损儿童组成研究组。借助盲文进行口腔健康教育和激励。向儿童教授改良的巴斯刷牙法，并进行所需的牙科治疗。受试者被随机分为含氟和不含氟两组。在基线、治疗后立即以及3、6和12个月间隔时评估简化口腔卫生指数、DMFT、乳牙龋失补牙面指数以及变形链球菌和乳酸杆菌计数。在研究开始和结束时使用问卷评估口腔健康意识。
基线时，平均简化口腔卫生指数、DMFT和乳牙龋失补牙面指数分别为2.72、0.47和0.51。12个月结束时，含氟组的简化口腔卫生指数得分显著降低。在不同时间间隔，含氟组和不含氟组的DMFT和乳牙龋失补牙面指数未见显著差异。经过口腔健康教育和综合治疗后，两组的变形链球菌和乳酸杆菌计数均有所减少；然而，在3、6、12个月结束时，与不含氟组相比，含氟组有显著下降。研究结束时口腔健康意识显著提高。
为视力受损儿童制定的口腔健康教育和激励措施在改善他们的口腔健康状况方面是有效的。含氟牙膏降低了变形链球菌和乳酸杆菌计数，改善了口腔卫生状况。
