Actual (reported)The maintenance of primary teeth until their exfoliation has been one of the main purposes of Pediatric Dentistry, are they representing the fundamental basis for proper occlusion of the permanent dentition. Often, injuries or extensive dental caries reach the pulp of deciduous teeth making maintenance on these dependent endodontic treatment arc. Thus, this study was to conduct a randomized clinical trial with longitudinal follow-up of two years, double blind, to compare the degree of success of endodontic treatment in primary among the most used folder, Guedes Pinto paste, and one Calcium hydroxide and iodoform paste to control, Vitapex.

Actual (reported)Success or failure of two endodontic treatments
The success or failure of endodontic treatments evaluated by the time spent in the tooth arch in clinical conditions of normality. Clinical criteria for determining success are: absence of fistula, absence of painful symptoms and pathological absence of adequate mobility and gingival contour. Radiographically, the success criteria are: absence / reduction of periapical bone rarefaction in anterior and absence / bone rarefaction in the furcation area of later, maintaining the periradicular space, root resorption compatible with the eruptive phase and absence of pathological bone resorption. To evaluate the reduction of lesions or appearance of new lesions will be between the initial and follow-up radiographs. Radiographs will be scanned and the end of the bone rarefactions starting area and will be measured on a software image analysis.
