A New Approach for Controlling Hemostasis During Canal Treatment: a Pilot Study

A new device (HYBENX®) has been developed with the purpose of destroying dental biofilm. The material contains a concentrated aqueous mixture of hydroxybenzenesulfonic acid (37%) and hydroxymethoxybenzene acids (23%), sulfuric acid (28%), and water (12%).

The investigators planned a clinical and microbiological study using the decontaminant device in order to destroy the dental biofilm of root canals in cases of irreversible pulpitis. The ability of the decontaminant device to immediately stop bleeding during canal instrumentation was found out accidentally during the procedures of this still unpublished trial.

Due to this fact, the investigators were interested in evaluating the coagulation property of the material. Therefore, the aim of this prospective study is to describe a new approach to obtain hemostasis during root canal therapy using a sulfonic/sulfuric acid solution.

A total of 15 teeth with irreversible and acute pulpitis were included in the study. After manual and mechanical instrumentation of the root canal, a sterile paper point was introduced in the canal, and a first score was given based on the blood quantity.

The solution was used to irrigate the bleeding root canal; then a second sterile paper point was introduced, and the same score was assessed. The null hypothesis was that there is no difference in root canal bleeding before and after the use of the solution (⎧=0)

Inclusion criteria

• tooth affected by irreversible pulpitis, single-rooted teeth associated with healthy periodontium, physiologic sulcus depth (<3 mm), and absence of bleeding on probing of the involved teeth.

Exclusion criteria

• patients with systemic diseases using anticoagulants, antibiotics, or anti-inflammatory therapies in the last 30 days, patients with allergy to sulfur in any form, and pregnancy.
