Introduction: The patient's desire toward achieving an esthetically pleasing face has not only increased the demand for orthodontic therapy but also necessitates the need for an esthetic appearance during the treatment period which led to the introduction of tooth-colored ceramic brackets and archwires. Materials and Methods: The experimental research was done using esthetic brackets (polycrystalline ceramic brackets with and without metal slot and monocrystalline brackets) and stainless steel archwires (uncoated, Teflon coated, epoxy coated, and rhodium coated) in both dry and wet fields. Two typhodont models were selected onto which the above-mentioned brackets were bonded and frictional resistance was evaluated using Instron machine for each of the archwire-bracket combinations in dry and wet fields. Results: The uncoated stainless steel (SS) wires showed less friction when compared to esthetic-coated SS wires. The frictional resistance was least for wet field when compared with dry field for all the groups and subgroups. It was also found that frictional resistance was minimum for Teflon-coated wires in polycrystalline ceramic bracket with metal slot (wet field) and maximum for rhodium-coated wires in monocrystalline brackets (dry field). Conclusion: Polytetrafluorethylene/Teflon-coated archwire and ceramic bracket with metal slot could be preferred as the esthetic archwire and bracket material of choice, respectively, due to their low frictional properties.
