Artificial tooth radiopacity for preclinical endodontic training

To evaluate radiopacity of artificial endodontic teeth for use in teaching activities and to know the perception of teachers regarding radiographic analysis.

Material and method

Thirty replicates of upper central incisors of three trade marks (Fábrica de Sorrisos, IM do Brasil and Real Dent) and a human incisor were used. On a radiographic sensor, human tooth and one artificial tooth of each marks were arranged. Radiopacity analyzes were performed using Photoshop^® in triplicate in four distinct regions: central portion of the crown and in the cervical, middle and apical thirds of the canal. The perception about the use of teeth as a practical teaching instrument was evaluated through a questionnaire applied to eight teachers of Endodontics. For statistical analysis of the radiopacity values ANOVA was used, followed by the Tukey test. Significance level of 5%. For the analysis of the questionnaire were used descriptive methods and percentage of data regarding the frequency of responses.

Result

There was a difference in radiopacity between the different teeth tested, in each region analyzed (P > 0.05). In the teachers' perception regarding the use of teeth in teaching, the teachers placed the following teeth for use: IM do Brasil, Fábrica de Sorrisos, Real Dent and human.

Conclusion

The radiopacity of the artificial teeth was different from the human teeth. The artificial tooth of the Fábrica de Sorrisos presented the highest values of radiopacity. The teachers considered ideal for use in teaching only the human teeth and the prototype Real Dent.
