Abstract

Introduction

The treatment of periodontal disease in multiradicular teeth with furcation involvement is a challenge for dentists, with unpredictable results.

Objective

To evaluate the characteristics of the active tip of periodontal curettes used for scaling the furcation roof, comparing the manual versus digital method.

Material and method

Forty-two Pádua Lima (PL) curettes of the Millennium® brand (n = 6 for each model) were evaluated: PL 1-2, PL 3-4, PL 5-6, PLW 1-2, PLW 3-4, PLW 5 -6, and PLF. The following were measured: total length of the coronary face (CTc, millimeters, mm), total length of the lateral face (CTl, mm), width of the coronary face (Lc, mm), and width of the lateral face (Ll, mm). The measurements were performed in duplicate.

Result

The results showed that weight varied among the curettes (p <0.05), however the handle diameter was similar for all instruments (p> 0.05). Considering that seven different types of curettes were evaluated, the parameters of CTl and Ll showed a statistical difference for all evaluated curettes (7: 7 ratio), with higher values for the caliper method compared to the software (p <0.05). There was a statistically significant difference between assessment methods for CTc and Lc measurements (p <0.05), showing that there was a coincidence of values in the proportion of 4:7 for measurements of CTc and 5:7 for Lc.

Conclusion

The comparison between methods generally resulted in lower values and greater variation for the digital method, thus favoring the use of the manual method to measure the active tip of periodontal curettes.
