Clinical Performance of Orthodontic Bands in the Restorative Treatment of Hypomineralised Primary Second Molars: a Randomised Clinical Trial
Sponsor: Universidade Federal do Rio Grande do Norte
Summary
This randomised clinical trial will compare the clinical performance and acceptability of orthodontic bands and preformed stainless steel crowns for the restorative management of hypomineralised second primary molars. Thirty children aged 5-10 years will be randomly allocated in a 1:1 ratio to receive either an orthodontic band or a stainless steel crown. One index tooth per participant will be evaluated immediately after treatment and at 6, 12, and 18 months. The primary outcomes will be marginal adaptation, retention, and the presence of carious lesions. Secondary outcomes will include biofilm accumulation and treatment acceptability among children and their caregivers.

Conditions
Interventions
Orthodontic band restorative treatment
Selective removal of softened carious dentine, when present, followed by restoration with conventional glass ionomer cement and placement of a prefabricated stainless steel orthodontic band cemented with glass ionomer luting cement.
Hall Technique with preformed stainless steel crown
Placement of a preformed stainless steel crown using the Hall technique, without caries removal, local anaesthesia, or tooth preparation. The crown will be cemented with glass ionomer luting cement.
