Aim: This study aims to measure sharpness of a sample of randomly chosen dental explorers (DEs) from King Saud University, College of Dentistry (KSUCD) compared to new ones. Materials and Methods: Sixty DEs were drawn out of random examination kits at KSUCD to be measured as a study group. Ten new DEs were measured to serve as control group. Tip diameter measurements were done for all seventy DEs under digital light microscope (n = 70) (μm). The comparison was done using SPSS (v. 16) at significance level P ≤ 0.05. Results: Mean tip diameter of the study group was 57.58 ± 20.06 while it was 30.34 ± 5.62 for control group. Independent sample t-test shows a significant difference between the two groups (P < 0.001). Conclusion: There is wide variation in tip diameter of study sample and difference in sharpness between study and control DEs. Clinical significance: Dull explorers might negatively affect the clinical judgment of marginal integrity of crowns.
