Significant variation in salivation by short-term suggestive intervention: a randomized controlled cross-over clinical study.

Introduction: Most dental procedures require a dry working environment. Although many evaporative drying methods are available, an additional reduction of salivary flow would often be helpful.

Methods: This prospective randomized cross-over study compares salivary production in 31 volunteers during direct, indirect, and non-suggestive (control group) intervention.
