Abstract
- AimIn this, in vitro study’s objective is to assess the shear bond strength (SBS) of metal and ceramic orthodontic brackets that have been adhered to enamel using a conventional acid etch/primer and self-etching primer (SEP) adhesive method. Materials and MethodsOne hundred excised human premolars were bonded on brackets and were divided into group 1 –Metal brackets were bonded on teeth and group 2 –Ceramic brackets were bonded on teeth. These two groups were further subdivided: subgroup 1a – 25 metal brackets bonded using conventional acid etch/primer adhesive system, subgroup 1b – 25 metal brackets bonded using SEP, subgroup 2a – 25 ceramic brackets bonded using conventional acid etch/primer adhesive system, and subgroup 2b – 25 ceramic brackets bonded using SEP; brackets were debonded using a computerized Instron universal testing machine. ResultsThe mean value of SBS of metal and ceramic brackets bonded using conventional acid etch/primer adhesive systems had higher SBS than those bonded using SEP. SBS ranged from 7.95 to 12.24 MPa which was in the acceptable clinical range. ConclusionSBS values of all four subgroups exceeded the range of 6–8 MPa observed to be acceptable for routine clinical use.
