Objective: To assess the efficacy of the novel ultrasonic Vector ™ ‐system system for subgingival debridement and to compare the results with conventional periodontal instrumentation in vitro and in vivo. Material and Methods: Forty extracted human teeth were treated in vitro: Vector ™ ‐system with polishing (VP) and abrasive fluid (VA), conventional ultrasonic system (U) and hand instrument (H). At intervals of 40 s, calculus removal was assessed using a 3D laser scanning device. Eight single‐rooted teeth were treated in vivo with the Vector ™ ‐system or hand instruments. Subgingival plaque samples were obtained for microbiological evaluation. After extraction, residual calculus was assessed by means of digitized planimetry. Results: In vitro efficiency of hand instruments was statistically higher compared with the conventional ultrasonic system ( p <0.05) and the Vector ™ ‐system with no difference between U and VA ( p >0.05) and VA and VP ( p >0.05). Residual calculus following in vivo instrumentation was not different in the Vector ™ and the hand instrument group ( p >0.05) but treatment time with the Vector ™ ‐system was statistically higher ( p <0.05). A similar reduction of periopathogenic bacteria could be observed in both groups. Conclusions: Using the Vector ™ ‐system, root surfaces can be debrided as thoroughly as with conventional instruments. However, treatment is more time consuming than conventional debridement.
