ABSTRACT: Purpose: In contemporary implant dentistry, bone mineral density (BMD) of the jaws is a patient-associated prognostic factor. The aim of this study was to compare the mandibular body BMD of dentate and edentulous patients using the dual-energy X-ray absorptiometry (DXA) technique. Materials and Methods: A total of 39 patients, 20 dentate and 19 edentulous, were included in this cross-sectional study. Mandibular body BMD was measured using the DXA technique. The variables were normally distributed; thus, the independent samples t-test was used for the determination of statistical significance between the dentate and edentulous groups (age, body mass index [BMI], DXA). Chi-square test was performed for identification of the gender differences between the groups. The Pearson correlation analysis was used to analyze the relationship between age, BMI, and mandibular body BMD. Note that p < 0.01 was accepted as the significance level. Results: There was no statistically significant difference between the dentate and edentulous groups in matching variables (age, BMI, and gender) (p > 0.01). There was a statistically significant difference regarding the mandibular body BMD in the dentate and edentulous group (p < 0.01) controlling for age, gender, and BMI. The edentulous group patients had higher mandibular body BMD values (1.27 ± 0.31 g/cm(2) ) than those in the dentate group (0.94 ± 0.22 g/cm(2) ). Conclusion: Comparison of the mandibular body BMD revealed that dentate patients had less dense bone than the edentulous patients. Further investigations are needed to determine the BMD of the jaws in different regions and for different systemic conditions.

ABSTRACT: The aim of this study was to compare the mandibular body bone mineral density according to bone mineral density status of spine and femur measured by dual-energy X-ray absorptiometry (DXA) technique in elderly edentulous individuals.
One of the factors that affect the survival rate of implants is bone mineral density (BMD) of the jaws.
Fifty edentulous elderly patients' (27 women and 23 men) spine, femur and the mandibular body BMDs were measured using DXA technique. BMD scans of the AP lumbar spine (L2-L3) and femur were classified using World Health Organisation criteria for bone mass.
There was a statistically significant difference between the normal femur group's-osteoporosis group's mandibular body BMD (p = 0.001) and femoral osteopaenia group's-osteoporosis group's mandibular body BMD (p < 0.001). The femoral osteoporosis group's mandibular body BMDs were lower than those of both the normal femoral and the femoral osteopaenia group subjects'.
Classification of edentulous mandibles according to low and high bone mineral densities is a problem in implant dentistry. The results of this study demonstrated that femoral bone mineral density status may be used to provide preliminary information about the bone mineral density of the mandibular body region in elderly edentulous subjects.

ABSTRACT: The purpose of this study was to analyse the anger expression styles, the continuous anger and personality types of players who play football in the professional league. The research group consisted of 133 soccer players who are playing in sports teams in the Turkish Super League: Ankara Sport Club, Gençlerbirliği Sports Club and Hacettepe Sports Club in the first league, Turk Telekom sports in the second league, and Keçiören Gücü Sports and Ankarademir Sports playing in the third league in the 2008-2009 football season. The Eysenck personality inventory was modified to Turkish by Bayar in 1983, having been developed by Eysenck and Eysenck in 1975 and the continuous anger-anger style scale (SOTO) was modified to Turkish by Ozer in 1994. The state trait anger scale (STAS) was originally developed by Spielberger in 1983. All these were used on soccer players participating in the study to determine the continuous anger and anger styles in this study. In the interpretation of data, a meaningfulness of p < 0.05, was applied by using regression analysis, the Kruskal Wallis Test, the one-way variance analysis (ANOVA) test and the Tukey test to find the differences among the groups. The SPSS (Statistical Package for Social Sciences) programme was used to find the accounted values and to evaluate the data. According to the results of this study, regarding the education level variable, while there was a meaningful difference between the continuous anger sub-dimension and anger control sub-dimension than continuous anger-anger expression styles, no significant difference was found among personality type sub-dimensions (psychoticism, extrovert, neurotic, false). In addition, a significant relationship was found between psychoticism, extrovert, neurotic, and lie sub-dimensions and the personality type sub-dimensions of professional players' constant anger-anger expression styles.
