The Twist2it is a unique disposable prophy angle (DPA). Unlike other DPAs that rotate a full 360 degrees, the Twist2it DPA oscillates in a reciprocating arc of 90 degrees (1/4 turn). This reciprocating motion requires the Twist2it DPA to be in constant contact with the tooth surface, in contrast to the on-and-off "dabbing" technique required with rotary DPA's. The manufacturer purports that debris spatter commonly associated with rotary DPAs is virtually eliminated. Furthermore, the Twist2It is advertised as producing less heat while causing less gingival irritation.
Clinical evaluators greatly appreciated the function of the Twist2it, reporting that it virtually eliminated spatter and produced less gingival irritation. Patients also appreciated the reduced gingival irritation, with only minimal reports of sensitivity during treatment. The Twist2it functioned flawlessly during evaluation and was quieter than rotary DPAs.
The Twist2it does require a different clinical application technique, because it is designed for constant contact with the tooth for maximum effectiveness. This might result in a learning curve for the clinician. Evaluators reported that it is less efficient than a rotary DPA in removing stains. It has a slightly larger head than rotary DPAs, which might make access more difficult. The Twist2it is also more expensive than a rotary DPA.

Twist2it Disposable Prophy Angle
Less spatter, heat, noise, sensitivity and gingival irritation than rotary DPAs.
More expensive than rotary DPAs. Less effective in stain removal.
The Bottom Line
Well performing, reciprocal-action, disposable prophy angle that produces less spatter and gingival irritation but is more expensive and less effective on stain removal.
