The effect of seven preventive treatments containing microrepair on the shear bond strengths of orthodontic brackets: An in vitro study

Objectives: this experimental aims to evaluate seven remineralising system containing microRepair and their prophylactic effect versus enamel lesions, caused by multibracket orthodontic therapy and early detachment of brackets. Materials and method: One hundred sixty freshly bovine teeth (incisors) were used and randomly collected into 8 groups (20 per group): group-1 was the control group (no treatment), group-2 was treated with BioRepair Kids 0-6 years (Coswell SpA), group-3 was treated with BioRepair Junior 7-14 years (Coswell SpA), group-4 was treated with BioRepair Pro White Plus (Coswell SpA), group-5 was treated with BioRepair Trattamento d’Urto Desensibilizzante Ripara Smalto (Coswell SpA), group-6 was treated whit BioRepair Plus ParodontGel (Coswell SpA), group-7 was treated with BioRepair Plus Denti Sensibili (Coswell SpA), group-8 was treated with BioRepair Pro Azione Anticarie Combinata Scudo Attivo (Coswell SpA). All the brackets were bonded using the same technique with transbond XT (3M Unitek, Monrovia, CA). All the bonded incisors were stored in 0,1% thymol solution until the start of treatment. Instron Universal testing machine was used to measure the.
