Avaliação <i>in vivo</i> da confiabilidade do localizador eletrônico Bingo na determinação do comprimento de trabalho, em situações de polpa vital e necrosada
Abstract
O objetivo deste trabalho foi avaliar in vivo, a confiabilidade do localizador eletrônico Bingo, na determinação do comprimento de trabalho, em situações de polpa vital e necrosada. Foram realizadas 56 aferições eletrônicas em pacientes entre 15 e 65 anos de idade, em tratamento na Disciplina de Endodontia da Universidade Luterana do Brasil (ULBRA – Canoas/RS). Dos dentes estudados, 25 possuíam canais com polpas vitais e 31, com polpa necrosada. Após isolamento absoluto e abertura coronária, estando a alça labial devidamente posicionada, introduziu-se, no interior do canal radicular, uma lima endodôntica de 25 ou 31 mm conectada a um dos pólos do aparelho, de diâmetro compatível com a anatomia do terço apical. Quando o visor do localizador eletrônico acusava estar a ponta do instrumento a 1mm da saída foraminal, os dentes foram radiografados. Com o auxílio de uma lupa, régua milimetrada e negatoscópio, foi mensurada, na radiografia, a distância entre a ponta do instrumento e o vértice radiográfico. Medidas compreendidas entre 0,5mm e 1,5mm foram consideradas confiáveis. Os resultados obtidos mostraram índice de confiabilidade de 92% para dentes com polpa viva e 83,87% para dentes com polpa mortificada. O localizador apical Bingo constitui-se em um excelente recurso auxiliar na odontometria, quando corretamente empregado.
UNITERMOS: odontometria; canal radicular; endodontia.
SUMMARY
The aim of this study was to determine, in vivo, the ability of Bingo electronic apex locator to determine root length in vital and non vital teeth. For this purpose, 56 measurements were proceeded in patients aging 15 to 65 years, undergoing treatment at the Endodontics Discipline of the Brazilian Lutheran University (ULBRA – Canoas/RS). The teeth comprised of 25 vital pulp root canals and 31 with necrotic pulps. Following rubber dam placement and access cavity, with the liphook adequately positioned, a # 25 to 31 K-file, connected to the Bingo device was placed within the root canal. The file diameter was compatible to the canal at the root apex. When the screen would denote the file to be 1mm short of the apex, radiographs were taken. With the help of magnifying lenses and a ruler, the distance between the tip of the instrument and the radiographic vertex was measured. Values between 0.5 and 1.5mm were considered adequate. The results showed 92% of measurements within the adequate limits in teeth with vital pulps and 83.87% in cases of necrotic pulps. Bingo apex locator was considered an axcelent means to help root length determination, when used adequately.
UNITERMS: root length; root canal; endodontics.
