AI Article Synopsis
- The study evaluated the WHO-621 periodontal probe from Brazil, focusing on its stability in dimensions and weight after sterilization.
- One hundred probes were measured for diameter, linear area, and weight, with specific mean values reported for the tips and colored bands.
- After undergoing steam or heat sterilization, some measurements of the probes showed significant changes, but neither sterilization method was found to be superior.
Article Abstract
This study technically assessed the WHO-621 periodontal probe made in Brazil as well as its dimensional and weight stability after sterilization. The following characteristics were measured in one hundred (100) new probes: diameter and linear area of tip sphere and beginning and ending references of its colored band by means of indirect computerized morphometric method, and weight, by means of a digital balance within 0.01 mm precision. Fifty (50) probes underwent one hundred (100) cycles of either steam or heat sterilization. The WHO-621 Trinity probe showed mean values of 0.66 mm in its longitudinal and 0.54 mm in its transversal sphere diameters; 0.40 mm2 in its sphere linear area; 3.56 mm and 5.76 mm for the beginning and ending of the colored band, respectively. Its mean weight was 10.12 g with small variation. Some of the measurements showed significant changes after both sterilization procedures. Neither of the sterilization methods showed to be more advantageous (Student's t-test, p = 0.05).
