This study evaluated the effectiveness of two microabrasion materials for the removal of developmental enamel opacities in young permanent maxillary incisors.
Using a split-mouth study design, 37% phosphoric acid and 18% hydrochloric acid were used for removal of visually unesthetic developmental enamel opacities of young permanent maxillary anterior teeth from 25 subjects (11-13 years old) by two microabrasion techniques for 10 and 5 seconds respectively. This procedure was repeated four to six times during each clinical appointment. The subjects were evaluated about their satisfaction with the treatment. Two blinded evaluators appraised both sides of the mouth using visual analog scale. The records were analyzed using Wilcoxon test.
The majority of the subjects (approximately 97%) reported satisfaction at the end of the treatment (p = 0.001**). Statistical significant reduction in enamel opacities was observed by evaluators immediately after microabrasion technique in group 1 (81.75%) and in group 2 (81.4%) (p < 0.002). Reduction was increased to 97.2% in group 1 and 96.7% in group 2 after 1 month.
Both microabrasion techniques showed comparative highly significant successful results in esthetic management of enamel opacities clinically and in terms of subject's satisfaction.
Developmental enamel defects like diffuse opacities due to high-fluoride content in water and demarcated opacities associated with positive dental history and are commonly seen in young permanent maxillary incisors of both boys and girls in their developing years. They are aware of unesthetic appearance of these newly erupted permanent anterior teeth and become highly motivated when informed about minimally invasive, patient friendly, cost-effective, and safe treatment like microabrasion for esthetic improvement. Both noninvasive microabrasion techniques using 37% phosphoric acid (group 1) and 18% hydrochloric acid (group 2) show comparatively high success results in treating enamel defects successfully to the subject's satisfaction along with their parents.
本研究评估了两种微磨除材料对年轻恒牙上颌切牙发育性釉质浑浊的去除效果。
采用双侧对照研究设计，分别使用37%磷酸和18%盐酸，通过两种微磨除技术，对25名受试者（11 - 13岁）年轻恒牙上颌前牙肉眼可见的不美观发育性釉质浑浊进行处理，处理时间分别为10秒和5秒。每次临床就诊时该操作重复4至6次。评估受试者对治疗的满意度。两名盲法评估者使用视觉模拟量表对口腔两侧进行评价。记录采用Wilcoxon检验进行分析。
大多数受试者（约97%）在治疗结束时表示满意（p = 0.001**）。评估者在微磨除技术操作后立即观察到，第1组（81.75%）和第2组（81.4%）的釉质浑浊有统计学意义的显著降低（p < 0.002）。1个月后，第1组的降低率增至97.2%，第2组增至96.7%。
两种微磨除技术在临床上对釉质浑浊的美学处理以及受试者满意度方面均显示出具有高度显著的成功结果。
发育性釉质缺陷，如因水中氟含量高导致的弥漫性浑浊以及与阳性牙科病史相关的界限性浑浊，在青少年恒牙上颌切牙中常见于处于发育阶段的男孩和女孩。他们意识到这些新萌出的恒牙前牙外观不美观，当得知像微磨除这样的微创、对患者友好、经济有效且安全的美学改善治疗方法时，积极性会很高。使用37%磷酸（第1组）和18%盐酸（第2组）的两种非侵入性微磨除技术在成功治疗釉质缺陷以使受试者及其家长满意方面均显示出较高的成功率。
