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
EXPERIMENTALPatients 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.
Restorative therapy
EXPERIMENTALPatients 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.
Extraction therapy and Restorative therapy
EXPERIMENTALPatients 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.
Control patients
NO INTERVENTIONPatients 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.
Interventions
