简要总结
the aim of this clinical trial is to compare the new micro-abrasion material "ANTIVET" compared to the conventional micro-abrasion material used widely "opalustre". to achieve better esthetics in cases of hypo-mineralized anterior permanent teeth of children and young adults.
both materials will be applied by the researchers and patient's teeth sensitivity and color change will be assessed immediately , after one month and after three months
详细描述
Materials and methods:
Enamel Microabrasion Even though only maxillary and mandibular hypominerlized incisors and canines were included in the current study, all teeth visible during smiling, laughing, or speaking were treated in this trial. The teeth were cleaned with pumice before treatment. Initial photographs of the teeth were taken.
Opalustre:
They were isolated with a rubber dam and then a fine-grit, water-cooled diamond bur was applied to the stained and white opaque enamel region for five to 10 seconds to enable penetration of the gel into the enamel. An approximately 1-mm- thick layer of 6.6% hydrochloric acid slurry with silicone carbide microparticles (Opalustre, Ultradent Products Inc, South Jordan, UT, USA) was applied to the affected tooth surfaces.
Antivet :

盲法说明
Participants, outcome assessors and data analyst will be blinded to the interventions during the clinical trial. After complete data entry of the trial, they will be unblinded to avoid any bias to either two groups. Outcome assessor chart was examined and filled up by two experts. Two principal Investigators and operators) will be blinded until generation of the allocation sequence. Later on, two invistigators will be unblinded within the treatment session due to different treatments packing and steps. Both investigators won't be involved in assessing the outcome. Informed Consent: both Investigators will be introduced the trial to patients regarding the main aspects of the trial.

结局指标
主要结局
patient satisfaction
时间窗: after 3 months
using a 5- point Likert scale ( 1= not at all satisfied, 5= extremely satisfied) likert scale: where 1 represents no improvement at all and 7 represents excellent improvement. photography conditions will be standardized during pre and post treatment photos
postoperative changes in teeth sensitivity
时间窗: change from baseline teeth sensitivity immediately after treatment ,change from baseline teeth sensitivity after one month from treatment and change from baseline teeth sensitivity after three month from treatment after
visual analogue scale (0:no pain,10:worst pain) - verbal analogue scale (no pain or distressing, miserable pain )
