We examined 233 cephalometric radiographs from individuals aged 18-70 years in Mashhad, Iran (78 males (33.5%) and 155 females (66.5%)). The dimensions of the sella turcica (diameter, length, and depth) were measured using Romexis software. The Kruskal-Wallis test was used to assess dimensional differences across skeletal patterns (p < 0.05). Pearson's correlation was used to analyze the relationships between dimensions and age, while the Mann‒Whitney test was used to compare dimensions between sexes. Data were analyzed using SPSS version 20 and ANOVA; normality was assessed with the Shapiro-Wilk test, and results are reported as mean ± standard deviation. Significant correlations were found between the dimensions and shape of the sella turcica. The longest length (6.78 mm) was associated with oval shapes (P = 0.003), whereas the greatest diameter (9.25 mm) was associated with flat shapes (P = 0.013). The length and diameter increased with age (P = 0.001 and P = 0.035, respectively). No significant relationships were observed with morphology, sex, skeletal pattern, or facial height (P >0.05). Sella turcica dimensions are influenced by age and floor shape but not by sex, morphology, or skeletal pattern.

Seventy samples were mounted in acrylic blocks and randomly allocated to seven groups (n = 10 per group): Group 1 (Golchai paste/Rubber cup), Group 2 (Morvabon paste/rubber cup), Group 3 (Sina paste/Rubber cup), Group 4 (Rubber cup-only), Group 5 (Brush-only), Group 6 (Golchai paste/brush), and Group 7 (Golchai paste-double amount/ higher speed rubber cup). Prophylaxis was performed for 3 s using a handpiece at 3000 rpm with 200 g pressure. The untreated half of each sample served as a control. A non-contact profilometer was utilized to evaluate the surface roughness. Statistical analyses were conducted employing ANOVA, Tukey's post-hoc test, paired t-tests, and Wilcoxon tests (α = 0.05). ANOVA indicated a significant difference in surface roughness among groups (p-value = 0.008). Pairwise comparison showed that Golchai paste reduced surface roughness when applied with a rubber cup but increased it when used with a brush, with a statistically significant difference between the two methods.
