Eligibility
Age
3 Years to 9 Years
Inclusion criteria
Inclusion criteria: Patients of both genders seeking dental treatment at the Pediatric Dentistry Clinic Bauru School of Dentistry, University of São Paulo (FOB-USP); aged between 3 and 9 years;authorized by their guardians through the signing of the Free and Informed Consent Form (FICF), and presenting at least one deciduous tooth with clinical and radiographic characteristics indicating and enabling the performance of pulpectomy. This allows for the treatment of various canals with different forms of physiological resorption typical of primary dentition, facilitating a comprehensive analysis of the accuracy of the locators. Clinically, the presence of painful symptoms; fistulas, or abscesses will be observed, along with the feasibility of performing absolute isolation and subsequent tooth restoration. Radiographically, the presence of rarefaction will be analyzed as an indicator of irreversible pulp involvement.
Exclusion criteria
Exclusion criteria: Children with any type of systemic health condition; teeth with previous endodontic treatment; teeth where isolation or subsequent restoration is not feasible; teeth with pulp calcification; or teeth with pathological internal or external resorptions that prevent the instrumentation of root canals.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome will be the accuracy of the working length determination methods. After all measurements have been performed in each canal of the specimens, the subtraction between the working length obtained by the radiographic method (control method) and the other working length determination methods will be calculated. Positive and negative values will indicate lengths greater or shorter than those determined by the radiographic method, respectively. The specific accuracy rate will be assessed within the tolerance ranges of ±0.5 mm and ±1.0 mm. The values will be presented as the number of canals (n) and the percentage (%) of working lengths that fall within the acceptable range, as well as the values that exceed or fall short of the range. | — |
