Abstract
The maintenance of the deciduous dentition in the oral cavity until the moment of its physiological exfoliation is extremely important, and the performance of pulp therapy is indicated when the cariogenic process is installed in a broad and advanced way, reaching the pulp tissue of the dental element. The most common treatment in these cases is pulpectomy, where the filling of primary teeth is performed using obturator pastes. The objective of this study is to review and discuss the literature on the antibiotic obturator paste based on tetracycline, chloramphenicol and zinc oxide and eugenol, called CTZ. This is a paste whose treatment does not require instrumentation of the root canals, being a procedure of tissue repair and sterilization of lesions (known as LSTR). The PubMed and Scielo databases were consulted using the keywords: "endodontic treatment" AND "LSTR". The 10 most current articles and also the articles considered most relevant were used. It has been observed that CTZ paste is not yet widely used, despite not being a new paste. Due to the practicality of the technique without instrumentation indicated for necrotic deciduous teeth, its use has grown, as well as scientific studies on it. In conclusion, the technique of using the CTZ paste is very effective, conferring great advantage in the treatment of non-cooperative patients, as it is easy, simple, and can be performed in a single session, presenting antibacterial power.
