Non instrumented endodontic technique using CTZ paste

Dental treatments in children are very complex to carry out and depend on different factors to obtain a clinical success, mainly depending in: selection of materials, clinical abilities and patient ́s cooperation. Objective: To know the biological properties of the CZT paste, as well as its advan-tages and disadvantages compared with other materials currently used in pulpar therapy in children. Method: A pulpectomy treatment was carried out by NIET (non-instrumented endodontic technique in the Pediatric Dentistry Clinic of the Postgraduate School, School of Dentistry, UNAM. All patients presented pulpar necrosis. Results: Recent studies have shown that the components of the CZT paste are more effective in pulpectomy treatment than other materials, finding asymptomatic patients after two weeks of treatment with this paste. Radiographic examination after 2, 4 and 6 months revealed a reduction or stabilization of the periapical lesion. Conclusions: The CZT paste has shown excellent results and reduces the bacteria concentration to minimal level. The characteristics of this paste allow the clinician to carry out pulpar treatment in less time and to obtain superior results comparing with conventional techniques.
