OBJECTIVE: To study the patient's acceptance, expectation, and experience of pain with orthodontic temporary miniscrews.

METHODS: Questionnaires were distributed to 165 potential temporary orthodontic miniscrew recipients or their parents. Using the numeric rating scale, patients who received miniscrews as part of their orthodontic treatment were also asked to rate the pain or discomfort experience after miniscrew placement.

RESULTS: A total of 165 subjects completed the first set of questions. There was a significant relationship between level of education and prior knowledge about orthodontic miniscrews (P=0.029). Even though only 12.7% had heard about miniscrews, 82.4% agreed to have miniscrews placed to facilitate orthodontic tooth movement. Eighty-three subjects who needed miniscrews as part of their orthodontic treatment completed two more sets of questions after 6 and 24 hours of miniscrew insertion. After 6 hours of miniscrew insertion, there was a significant difference in pain perception between men (mean =2.6±2.2) and women (mean =2.1±1.5; P=0.03). After 24 hours, there was no difference between men (0.2±0.4) and women (0.2±0.5; P>0.05). Postplacement, 32.5% did not require any pain medication, while 59.1% required a single dose and only 8.4% required two doses. A total of 76 patients (91.6%) said that they would recommend this procedure.

CONCLUSION: Patients do accept miniscrew as a treatment option in orthodontics. Postoperative pain is significantly low. The acceptance of miniscrews was not related to patient's previous knowledge of the device, and patients preferred miniscrews to extractions.
