【 摘 要 】

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 post-traumatic complications.
