Aims and objective The aim of the study is to investigate intensity location and duration of pain experienced by patients following insertion of orthodontic fixed appliances in the initial stage during biting chewing and clenching of teeth.Materials and method The appliances used were either Beggs appliance or per-adjusted edgewise appliance on all teeth except first molar. The initial wires Nickel-titanium stainless steel Wilcock wires were inserted. Pretreatment questionnaires were given at the appointment of initial wire insertion to 80 patients. All the patients were required extraction of four first premolar teeth for the orthodontic treatment.Results In almost one-third the patients 26 in the present study the treatment experience was generally characterized as better than pre-treatment expectations. Another one third 27 reported the pain experience was as expected before the start of treatment. One third 27 of the respondents answered that treatment was worse than they had expected before the treatment commenced.Conclusion there is large individual variation with attendant differences in the pain threshold.However these differences would appear to be consistent present study all patients reported relatively moderate pain within 24 hrs after placement of fixed appliance. Till date only a few studies have attempted to quantitatively document orthodontic pain reported by the patients
