Molar Incisor Hypomineralization Clinical Trial

Official title: Comparative Evaluation of Giomer Varnish vs Fluoride Varnish as Desensitizing Agents Among a Group of Children With Molar Incisor Hypomineralization : A Controlled Clinical Trial

Status Not yet recruiting

Clinical Trial Summary

this clinical trial's aim is to compare two desensitizing agents available in the market to prove which one is more efficient in children with molar incisor hypomineralization complaining from hypersensitivity

Clinical Trial Description

Interventions

The principal investigator will carry out all treatment procedures, and the patients will be assigned.

For both interventions:

1. Informed consent from participating parents.

2. Baseline records photographs and personal data collection .

3. Allocation (concealed by withdrawing a sealed opaque envelope containing eight times folded paper containing the type of desensitizing agent that will be used then writing the patient name and I.D. on it and will be opened in the first visit of treatment).

4. Diagnostic chart with personal, medical, and dental history will be filled.

5. Evaluation of oral health-related quality of life as a baseline, using the Arabic version of the child perception questionnaire-8-10m indicated for children from age 8 to 10 years old, it consists of 25 questions related to oral symptoms (5 questions), functional limitations ( 5 questions), emotional wellbeing (5 questions) and social wellbeing ( 10 questions), responses are made on an ordinal scale ( 0 = never, 1 = once/twice, 2= sometimes, 3= often, 4= every day/ almost every day).

6. Teeth will be cleaned with prophylaxis paste using a low-speed contra brush then teeth will be inspected using a dental mirror and reflected light of the dental unit and the teeth must be moist during the clinical examination to assess the clinical inclusion criteria according to European Academy of Pediatric Dentistry diagnostic criteria.

7. Preoperative, intraoperative, and Postoperative photographs will be taken.

8. Prior to initiation of the treatment, all included teeth will be evaluated for pain in response to an evaporative stimulus using the triple syringe, the air is directed perpendicular to teeth and held at approximately 2 mm for 3 seconds and children are informed to raise their hands or fingers when any discomfort is felt and then the pain is evaluated using the Wong-Baker faces rating scale and Schiff scale.

9. Teeth also are evaluated to thermal stimulus, using an anesthetic carpule refrigerated at 4c for at least 24 hours and the carpule is to be placed in contact with the tooth for 1 to 5 seconds according to child response and pain is to be evaluated as with evaporative stimulus.

10. Application of rubber dam for isolation.

11. Prior to treatment, teeth received prophylaxis using pumice paste, cleaned using the triple water syringe, and dried.

Children will then be allocated into either one of the groups alternatively depending on the desensitizing agent used as follows:

Group I (Experimental group) Giomer varnish. Group II (Control group) Fluoride varnish. ;
