[Predictive value of tactile sense in electronic endodontometry]

A statistical study has been conducted in order to study the benefit afforded by tactile sense in endodontometry. The study is based on 154 electronic measures (Dentometer, Endoradar, MEO2) and 90 tactiles ones, all radiographically controlled. Results show that: 1. The rate of good electronic measures is, as a whole, the same as tactile ones. 2. The risk of wrong measures is twofold in the case of narrow root canal, necrosis or molar treatment. 3. The risk lessens in the case of a pulpectomy when the electronic measure is associated with a tactile one: 48.38% success instead of 25%, in tactile sense: 48.8 success instead of 56.25%. Evidently, the study bring up to date the tactile perception in endodontometry in the case of pulpectomy.
