Esthetic Management of Anterior Teeth Utilizing Two Micro Abrasion Treatments
Condition: Hypomineralization of Enamel
Study type: Interventional

Summary: 
      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
    

Detailed description: 
      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 :

      Teeth treated will be isolated first then Vaseline will be placed on gingival sulcus before
      placing dental dam., patient will be seated at a 45 degree angle. Five drops of Antivet in
      the plastic mixing well that comes. Then ANTIVET solution will be applied over the tooth's
      surface using a well condensed cotton pellet (approximately a 3 mm diameter). When the cotton
      pellet is pigmented by the tooth's staining, it will be changed for a new one. This process
      may take about 1 to 5 minutes per tooth, It should take no longer than 15 minutes from the
      moment the solution contacts the tooth's surface

      Sampling:

      Thirty participants, aged between 9-18yrs, with dental hypo mineralized discolored anterior
      teeth and who met the following inclusion and exclusion criteria will be selected for the
      study.

      Recruitment:

      The two principal investigators and operators screened patients in Outpatient clinics of
      departments of Pediatric Dentistry and Public Health in Faculty of Dentistry - Beni-suef
      University & Restorative Dentistry- Faculty of Dentistry in the British University in Egypt
      irrespectively. The screening process was continued until the target population was achieved.

      Patients will be randomly allocated in both treatment groups

      Blinding:

      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. 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.

      A written informed consent forms (Arabic and English versions) were signed by all patients
      participated in the trial. The protocol, informed consent forms, participant education and
      recruitment materials will be reviewed and approved by the Ethical Committee of Faculty of
      Oral and Dental Medicine- Beni-Suef University.

      outcomes will be assessed immediately after the procedure, 1 month and 3 months Pre-operative
      and post operative photographs will be taken to document color improvement in each visit
