Summary
This is a controlled, randomized, double-blind clinical study (researcher and research
participant does not know which group they belong to), with the objective of evaluating
clinical and radiographic performances of primary molar canal treatments with necrotic pulps
using two obturator pulps. The CTZ paste (composed of chloramphenicol, tetracycline, zinc
oxide and eugenol) and the ZOE paste (composed of zinc oxide and eugenol). The CTZ paste
represents an alternative treatment that makes possible to treat canals of primary molars in
a simplified way, without instrumentation of root canals. Studies with the CTZ pulp have
demonstrated satisfactory clinical and radiographic results in addition to biocompatibility
and good antimicrobial action. The zinc oxide and eugenol paste has been studied, presents
good clinical and radiographic results, it is indicated by the American Academy of Paediatric
Dentistry and requires mechanical chemical preparation of the root canals.
Children of both sexes, frequenters of the paediatric dentistry clinic of the Federal
University of Piaui who present lower deciduous molars with clinical history and / or
radiographic evidences of pulp necrosis will participate in the study.
The hypothesis of the study is that both pastes present similar clinical and radiographic
results.
