Details and patient eligibility

About

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.

Full description

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.

Enrollment: 64 estimated patients

Sex: All

Ages: 6 to 9 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

Exclusion criteria

• Primary molars teeth previously manipulated, with obliteration of the root canal, with bone reabsorption involving the crypt of the permanent tooth, internal or external pathological or physiological reabsorption involving more then half of the shortest root and unrestorable tooth
