Qualitative Analysis of the Enamel Surface After Removal of Remnant Composite

Postupak čišćenja zaostatnoga kompozita pošto je skinuta ortodontska bravica, problem je jer se često ošteti caklinska površina. Svrha je ovoga rada odrediti metodu čišćenja zaostatnoga kompozita koja najmanje oštećuje caklinsku površinu. Istraživanje je provedeno in vitro, na 30 premolara. Bravice su lijepljene i skidane istim postupkom, nakon čega su zubi nasumce podijeljeni u tri skupine. Prva je čišćena Band Driverom, druga tungsten karbidnim svrdlom, a treća klijeπtima za skidanje kompozita. Uzorci su analizirani svjetlosnim stereomikroskopom Olympus. Provedena je raščlamba mikrofotografija i procijenjen Surface Roughness Index (SRI). Najmanje izgrebana površina cakline ostala je nakon tungsten karbidnoga svrdla. Ono se je pokazalo najneškodljivijim sredstvom za čišćenje površine cakline od zaostatnoga sloja kompozita nakon skidanja ortodontskih bravica.Choosing the method of remnant composite removal after debonding is a problem, because most techniques cause deep scratches on the enamel surface. The purpose of this study was to determine the method that causes the least damage to the enamel. The study was carried out on a sample of 30 premolars. After brackets had been bonded and debonded, using the same procedure, the samples were divided at random into three groups. The composite remnants in the first group were removed using the Band Driver, in the second group using a tungsten carbide bur and in the third group using composite removing pliers. The samples were analysed using a light stereomicroscope (Olympus). The photomicrographs were graded and the SRI (Surface Roughness Index) “calculated”. The best enamel surface appearance was determined after using the tungsten carbide bur, which is considered the method which causes the least damage to the enamel surface
