Radiopacity of Gutta-Percha Points at Thinner Sample Thicknesses

Twelve test specimens each for six commercial gutta-percha points were evaluated for radiopacity at thicknesses of 0.3, 0.6, and 1 mm. Data from digital radiographs were analyzed using ANOVA and Tukey tests at a 5% significance level. The study by Bruna Lucian Petry concluded that all materials met the ANSI/ADA specification minimum, with Odous and Tanari showing less radiopacity at the thinnest 0.3 mm sample.

Use Cases

• Compare radiopacity performance of different gutta-percha brands based on the six materials tested.
• Analyze the effect of sample thickness on material radiopacity based on tests at 0.3, 0.6, and 1 mm.
• Validate material compliance with ANSI/ADA Specification #57 and ISO 6876/2001 standards based on the reference aluminum stepwedge method.

Strengths

• Experimental data includes 12 test specimens for each of the six materials, providing a basis for statistical analysis.
• Radiopacity was quantified against a graduated aluminum stepwedge from 1 to 10 mm, providing a standardized reference.
• Statistical analysis was performed using ANOVA and Tukey tests at a 5% significance level.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• The dataset's scale and specific file formats are not described.
