About

The aim of this study is to compare the clinical outcome of using direct esthetic composite restorations in managing MIH cases and the use of preformed metal crowns.

Full description

Molar incisor hypomineralization can represent a serious and challenging clinical management problem. Children with MIH require higher levels of treatment needs and demonstrate considerable management problems.

For most severely affected MIH molars, direct esthetic restorative materials or preformed metal crowns will be the treatments to choose between. A number of aspects which could support decision-making, however, are not clearly demarcated. First and foremost, it is not clear if both treatments are similarly acceptable for patients and providers.

Enrollment: 60 patients

Sex: All

Ages: 7 to 12 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Children with MIH in one fully erupted molar or more.
2. Age ranging from 7-12 years.
3. cooperative children
4. Good general health.

Exclusion criteria

1. patients participating in other experiments.

2. Patients with parents planning to move away within the following year.

3. Patients with only mildly affected MIH molars that do not require extensive restorative treatment.

4. MIH-affected molars that have a very poor prognosis and require extraction.

5. First permanent molars that are affected with other developmental defects, such as hypoplasia, dental fluorosis or amelogenesis imperfecta.

60 participants in 2 patient groups

Direct composite restorations

Active Comparator group

Description:

bulk-fill composite (Filtek BulkFlow, 3M Espe) will be used after infiltration or block anaesthesia for affected molar, following by carious tissue removal. Marginal bevelling of enamel will be performed. A universal adhesive (Scotchbond Universal, 3M Espe) will be placed after selective enamel etching A bulk-fill composite will be used and covered using a nanohybrid composite, (Filtek XT, 3M Espe).

Treatment:

Procedure: Direct composite restorations

Performed metal crowns

Active Comparator group

Description:

PMCs (3M Espe, Seefeld, Germany) will be placed after infiltration or block anaesthesia for affected molar, followed by removal of carious dentin and enamel, Tooth preparation for fitting the crown, The correct size of crown will be chosen, and then Cemented with glass ionomer luting cement (KetacCem, 3M Espe).

Treatment:

Procedure: Direct composite restorations
