Introduction. Forces generated in orthodontic treatment with fixed appliances
create tension and compression zones in the periodontal ligament resulting in
a painful experience for patients. In the first phase of orthodontic
treatment, when leveling of teeth is needed, nickel-titanium (NiTi) archwires
can be completely engaged in brackets, even in the cases of extreme crowding,
exerting small forces. There is a great individual variation in the pain
perception related to the application of orthodontic forces. Objective. The
aim of this study was to investigate the pain perception among patients with
dental crowding after insertion of six different NiTi orthodontic archwires
as a part of fixed appliances in the first stage of orthodontic treatment.
Methods. The study was conducted on a sample of 189 orthodontic patients
receiving one of six different either superelastic or heat activated NiTi
archwires, in the first phase of orthodontic treatment. Pain perception was
evaluated in groups of patients with different degree of crowding. The
modified McGill Pain Questionnaire with Visual Analogue Scale was used to
evaluate the quality and intensity of pain. Statistical analysis was
performed using simple descriptive statistics, and Pearson`s chi-square test
with statistical significance of p<0.05. Results. Majority of patients
reported pain as discomfort or pressure of moderate intensity caused by
chewing or biting, started within 12 hours, carried on for 3-4 days, and
decreased over time without self-medication. Conclusion. No correlation was
found between pain perception among patients with different types of NiTi
archwires and the degree of crowding.
