Uso e eficácia da pasta CTZ (Cloranfenicol, Tetraciclina e Óxido de Zinco e Eugenol) : revisão de literatura.

Abstract

Considering the importance of keeping deciduous teeth in the mouth, to maintain space for the permanent successor tooth, among other aspects, it is If necessary, the dentist intervenes in different treatment needs, including exfoliation. Among these needs is endodontics, which traditionally recommends the instrumentation of root canals. However, there is also a technique that recommends not instrumenting the root canals and using pastes. The most used paste in these situations, in Latin America, including Brazil, is CTZ (antibiotic paste composed of chloramphenicol, tetracycline and zinc oxide). Thus, the objective of this work was to analyze the possibility of using CTZ paste in endodontics for primary teeth, especially in public health. To this end, a literature review was carried out, evaluating the indications, advantages and limitations of using the paste. Most of the articles found were case reports, with few articles evaluating the use of the paste through longitudinal clinical studies. The technique is indicated for deciduous teeth with pulp necrosis, where maintaining the tooth for longer contributes to the child's oral health. The success of the treatment is based on the correct diagnosis, through careful anamnesis, clinical and radiographic examinations, as well as the adequate execution of the technique and monitoring of patients, through clinical and radiographic examinations. One of the advantages of using CTZ paste is its ease of use, when compared to the conventional technique, as it recommends treatment in a single session, eliminating the need for root canal instrumentation. Most non-instrumental treatment failures are observed only in radiographic evaluation, making this exam essential for monitoring treated cases, which would be a limitation for its adoption in services that do not perform x-rays. The technique is contraindicated in patients at risk of infective endocarditis, pre- or post transplant patients, immunocompromised patients, or with a history of allergy to any of the medications used in the pastes. Furthermore, it should not be used on teeth that cannot be restored; or when root resorption involves more than half of one of the roots; teeth with extensive internal resorption, root calcification and perforation of the floor of the pulp chamber. It is concluded that the use of CTZ paste in the endodontic treatment of primary teeth is a more conservative option, easier to use, faster and with less need for available instruments, when compared to the conventional technique, which favors its use in healthcare. public. However, it requires an initial x-ray and clinical and radiographic follow-up, which is not always available in public services. Carrying out more follow-up research on CTZ paste would make it possible to increase the level of evidence of its use in primary dentition, favoring its use in public health.
