Abstract
Aim: To evaluate clinical and radiographic aspects before and after endodontic treatment with an
intracanal dressing paste composed of calcium hydroxide, chlorhexidine and zinc oxide in
traumatized teeth followed-up for 1 year. Methods: Patients (n=105) treated at the Dental
Trauma Service of Piracicaba School of Dentistry, Brazil were enrolled in the study. Two groups
of teeth were formed: immature (G1) (n=28) and completely developed teeth (G2) (n=174). All
teeth were endodontically treated and received an intracanal dressing with a paste composed
by calcium hydroxide, 2% chlorhexidine gel and zinc oxide at a 2:1:2 rate. Clinical and
radiographic aspects were evaluated initially, monthly and after 1-year. Results: Most of the
immature teeth suffered extrusive luxation (39.3%), whereas intrusive luxation (40.8%) was
more common in completely developed teeth. There was a significant reduction in pain on
percussion and mobility (p=0.0001) for immature teeth. Mature teeth showed reduction of
spontaneous pain, fistula, mobility and pain on percussion (p<0.0001). Radiographic examination
showed decrease in all evaluated parameters for both groups, in addition to stabilization of root
resorption. Conclusions: This new intracanal dressing paste for traumatized teeth showed
promising results in both immature and completely developed teeth, and may prevent posttraumatic
complications.
