NCT06228989

Brief Summary

The aim is to long-term evaluate extraction or restoration therapy, of first permanent molars with extensive treatment needs as a result of severe MIH in a national multicenter study concerning dental fear and anxiety, oral health-related quality of life, jaw development, and health economics.

Outcome Measures

Primary Outcomes (3)

  • Dental fear and anxiety

    Questionnaire: Children's Fear Survey Schedule - Dental Subscale (CFSS-DS). Range 15-75, lower score indicated lower dental fear and anxiety

    At baseline - age 6-9 years (T0), At 1st follow-up - age 11 years (T1), At 2nd follow-up - age 15 years (T2))

  • Oral helth-related quality of life

    Questionnaire: Short form of Child Perceptions Questionnaire for 11-14-year-old children (CPQ11-14). Range 0-64, lower score indicated better oral helth-related quality of life

    At baseline - age 6-9 years (T0), At 1st follow-up - age 11 years (T1), At 2nd follow-up - age 15 years (T2))

  • Health economics

    Journal extract: nummber of dental visits and the length of dental visits. More dental chairtime indicates a higher health economic impact.

    At baseline - age 6-9 years (T0), At 1st follow-up - age 11 years (T1), At 2nd follow-up - age 15 years (T2))

Study Arms (4)

Extraction therapy

EXPERIMENTAL

Patients exclusive treated with extraction therapy of any first permanent molars due to severe MIH. Affected first permanent molars were dignosed with MIH degree 4-6.

Procedure: Extraction therapy

Restorative therapy

EXPERIMENTAL

Patients exclusive treated with restorative therapy of any first permanent molars due to severe MIH. Affected first permanent molars were dignosed with MIH degree 4-5.

Procedure: Restorative therapy

Extraction therapy and Restorative therapy

EXPERIMENTAL

Patients undergoing combined treatment of both extraction therapy and restorative therapy of their first permanent molars due to MIH. Affected first permanent molars treated with extraction therapy were dignosed with MIH degree 6. Affected first permanent molars treated with restorative therapy were dignosed with MIH degree 4-5.

Procedure: Restorative therapyProcedure: Extraction therapy

Control patients

NO INTERVENTION

Patients devoid of any enamel developmental defects, attending the Public Dental Service in Region Västra Götaland, constituted a basis for the control patients. These controls were matched in terms of gender, age, and socio-economic factors, with each study patient paired with seven potential control patients.
