Patricia A. Murray Dental Corp. v. Dentsply International., Inc.

Plaintiffs sued Dentsply, Cavitron's manufacturer and marketer, on behalf of California dentists who purchased the Cavitron ultrasonic scaler for use during oral surgical procedures, under the Unfair Competition Law (UCL) (Bus. & Prof. Code, 17200) and for breach of express warranty. Plaintiffs claim that the Directions for Use indicate Cavitrons can be used in “[p]eriodontal debridement for all types of periodontal diseases,” which by implication included oral surgery; in fact, they cannot because the device accumulates biofilm in its waterlines and is incapable of delivering sterile water during surgical procedures. Following a remand, the trial court certified the class, conducted a bench trial, and rejected all claims. The court of appeal affirmed, agreeing that plaintiffs, as licensed dentists, were well aware that biofilm forms in all dental waterlines and that Cavitrons do not produce sterile water. The evidence failed to establish that the class was likely to be misled. The weight of the evidence established that dental professionals did not understand the warranty that the Cavitron was suitable for use in “[p]eriodontal debridement for all types of periodontal diseases,” as a statement that the Cavitron delivered sterile water or water without biofilm.
