Influence of Working Length Methods in the Performance of Pulpectomies in Primary Teeth

Universidade Federal de Santa Catarina64 enrolled

Overview

Verify, through a randomized double-blinded clinical trial, the influence in the performance of pulpectomies in primary teeth, based on two working length methods, electronic and radiographic.

Samples will be composed of children between 6 and 9 years of age, with the need for endodontic treatment in primary teeth. They will be submitted to anamnesis, clinical and radiographic exams for identification of eligibility criteria for the study. These patients will be divided randomly into 2 groups: G1 - pulpectomy with working length method performed through radiography (n=100) and G2 - pulpectomy with working length method performed with the aid of an apex locator (n=100). Endodontic treatment will be done by a single trained operator. After definite restoration and final radiography, an evaluation of the obturation quality will be performed by another blinded operator, who will evaluate the appropriate obturation length. The clinical treatment success and the radiographies will also be analyzed during a period of 24 months through clinical and radiographic exams, also by a blinded operator.

Interventions

PulpectomiesOTHER

Primary teeth pulpectomy is an important treatment option for necrotic teeth. The correct working length will determine a better chemical and mechanical disinfection of the root canals, without demanding the surrounding periapical tissues and dental germs. In addition, it decreases the chance of a sub or over-filling, which also may interfere with the achievement of the success.

Outcomes

Primary Outcomes

Outcome Electronic Apex locator

The use of an electronic apex locator for the achievement of working length in primary teeth pulpectomies will demonstrate a similar or better result than the radiographic method for the obturation adequacy. Also it will show a closer or a better result in the evaluation of the clinical and radiographic success in a long-term treatment.

Time frame: Evaluations will be done during 24 mouths after the pulpectomy performance

Secondary Outcomes

Difference in length measurement methods for pulpectomies in primary teeth

Evaluate if there is a significant difference in the accuracy of electronic apex locators compared to the conventional radiography in working length measurements

Time frame: Evaluations will be done during the pulpectomy performance

Influence of working length measurement methods in the obturation level of pulpectomy in primary teeth

Evaluate the effect of two working length measurement methods in the obturation level of pulpectomy in primary teeth

Time frame: Evaluations will be done after the pulpectomy performance
