Dear Doctor
My name is Dr TF Mothobela, I am a registrar at the University of Limpopo (Medunsa). I humbly request your participation in this questionnaire where I intend to assess the utilization of Temporary Anchorage Devices (TADs) amongst South African orthodontists. TADs in the study refer to mini screws, mini-implants, micro screws and mini screw implants excluding plates and osseointegrated dental implants.

The questionnaire is completely anonymous and contains only a few questions which will take no longer than 5 minutes to complete. All answers are entirely voluntary, but a completed questionnaire will be greatly appreciated.

Sincerely
Dr Mothobela
