Pain is a subjective response showing large individual variations, when arising from orthodontic force application is a major concern for patients, parents and clinicians. Diclofenac is a potent anti-inflammatory drug that is well suited for local use in the oral cavity. The drug results in decreased production of Prostaglandins hence, reduce inflammation or swelling and pain.

 â€œIt is hypothesized that diclofenac oral rinse would be a better alternative to its systemic administration, in terms of patient acceptance"

There are several other non-pharmacological methods for orthodontic pain relief and masticatory stimulation of the periodontal ligament such as the chewing of gum or use of bite wafers has been reported to alleviate pain induced by the application of orthodontic force. Chewing rubbery materials allows blood flow in compressed areas of the periodontal ligament and prevents the formation of pain-inducing inflammatory metabolites, thereby attenuating pain perception. Hence, this study is planned to assess and compare the efficacy of diclofenac (local and systemic form-oral route) and chewing gum (non sticky and sugar free) with control group in the management of orthodontic pain

Procedure of conduction of research: - The participants will be evaluated on the basis of mild to moderate crowding followed by the inclusion criteria. Randomized allotment will be done in the four groups respectively. A 0.014” Cu NiTi wire will be placed in patient’s mouth after bonding is done with conventional metal brackets. Pain relief remedies will be provided as per group allotments with a questionnaire which will be collected in the next appointment and instruction will be given. The filling of questionnaire on proper time will be assessed through telephonic reminders.

Predesigned pain questionnaire including visual analog scale will be given to the patients and will be collected in the next appointment.
