Endodontic Treatment of Necrotic Primary Teeth With Guedes Pinto Paste: A Randomized Clinical Trial

February 27, 2018 updated by: Fausto Medeiros Mendes

Endodontic Treatment of Primary Teeth With Guedes Pinto Paste: A Randomized Clinical Trial

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.

Study Overview

Detailed Description

After approval by the ethics committee of the patients Faculty of Dentistry, University of São Paulo that having root canal filling of primary teeth will be invited to participate in the study. A clinical examination and prior radiographic diagnosis and also a quality of life questionnaire regarding oral health (- ECOHIS Early Childhood Oral Health Impact Scale) will be-held. The patient will be randomized to one of two groups and will be held endodontics by a blind handler. The patient will be accompanied with periods of one week, six months, 12 months and 24 months by a blinded evaluator. At the last visit of the review ECOHIS questionnaire will be reapplied to those responsible. The outcome will be the success or failure of endodontic treatments evaluated through permanent tooth in the arch on clinical and radiographic conditions of normality. The longevity of the treatments will be evaluated by estimating survival rates by Kaplan-Meier. The differences between the survival rates according to the type of proposed endodontic treatment will be analyzed using the log-rank test with a minimum significance level of 5%.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Success or failure of two endodontic treatments
Time Frame: two years
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.
two years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Quality of the obturation obtained with the two root canal filling pastes
Time Frame: two years
The quality of the filling will be assessed by a blinded examiner according to two criteria. Through an index that ranks the shutter in satisfactory, questionable or unsatisfactory and through evaluation of digital radiographic images with the aid of a computational tool (Autodesk AutoCAD), where the visible areas of the root canal will be measured in previous radiographic examination and their measurements of the area of the root canal filling pastes filled with channels. The influence of the quality of the filling in the successful treatment will also be assessed.
