Aim.To evaluate the effectiveness of the mathematical model for determining the probability of osteopenic syndrome in patients with multifocal atherosclerosis.Materials and methods. The study included 251 male patients with verified atherosclerosis of the coronary and carotid arteries. The average age of the patients was 60,56±8,7 years. All patients included in the study performed multispiral computed tomography of coronary and carotid arteries with a quantitative evaluation of calcification by the method of Agatston (calcium index and equivalent weight of calcium deposits), color duplex scanning of carotid arteries, densitometry. The obtained data were used to calculate the probability of having an osteopenic syndrome (р) using a mathematical model. Criterion for the risk of osteopenic syndrome in the patient is the value р>0,688. The results of the analysis were compared with the densitometry data chosen as the reference method.Results. According to the quantitative assessment of coronary artery calcification in patients with osteopenia and osteoporosis, significantly higher values of the calcium index and equivalent weight of calcium deposits were observed than in patients with normal bone mineral density. Regardless of the presence of bone mineralization, more than half of the respondents (66,7% of patients with normal bone mineral density and 59,6% of patients with osteopenic syndrome) had coronary artery stenoses up to 50%. Calcification and presence of stenosis more than 30% of carotid arteries prevailed in the group of patients with osteopenic syndrome. The results of calculating the probability of having an osteopenic syndrome using a mathematical model indicate that it is highly prevalent in the sample (69,3%) and does not differ significantly from the densitometry data (70,1%). The sensitivity of the mathematical model was 89,8%, the specificity was 78,7%, the prognostic value of the positive result was 90,8%, the prognostic value of the negative result was 76,6%.Conclusion. The mathematical model for assessing the probability of osteopenic syndrome is highly diagnostic in men with multifocal atherosclerosis.

Published: January 2019

SUMMARY
Light activation is an important clinical step for achieving success in restorative procedures. This study evaluated the influence of beam profile from different light emission tip types of multiwave light-emitting diodes (LEDs) on the curing profile of resin-based composites. Experimental composites were produced containing either camphorquinone (CQ) or diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO) as a photoinitiator. Multiwave LEDs with either a bundle light guide tip (Bluephase G2, Ivoclar Vivadent) or a microlens tip (VALO Cordless, Ultradent) were characterized using a beam profiler. Block-shaped samples (5×5×3 mm depth) of the two composites were cured in a custom-designed mold with the multiwave LEDs positioned to compare the regions exposed to the 420-495 nm (blue) and 380-420 nm (violet) emittances. To map the curing profile, the degree of conversion (DC) of longitudinal thin cross sections from each block was evaluated using transmission FT-NIR. Radiant exposure transmitted through the composites during curing was evaluated at different thicknesses. Data were analyzed using analysis of variance and Tukey test (α=0.05; β=0.2). The results indicated that there were differences in the beam profile and the overall radiant exposures transmitted through the composites using each multiwave LED (p&lt;0.01, df=1 F=73.18). However, there were no differences in the curing profiles provided by the two multiwave LEDs (p=0.89, df=12 F=0.52), and similar effects were found according to the different LED emittance regions (p=0.09, df=5, F=2.11). When considering up to 1 mm in depth, no differences in the DC were found between the composites containing either photoinitiators. Starting at 2 mm in depth, the composite containing TPO showed a decrease in DC in the 420-495 nm emittance region, while the composite containing CQ showed a similar decrease in cure efficiency only at 3-mm depth under both 380-420 nm and 420-495 nm emittance regions. Thus, despite the fact that the nonuniform light beam emitted from the two multiwave LEDs was visually distinctly different when delivering 24 J/cm2, this difference did not seem to affect the curing profile of the composites. However, light transmission within 380-420 nm seems to be reduced with depth, directly affecting the curing profile of composites containing a photoinitiator with absorbance falling within this emission range.

SUMMARY
The aim of this study was to evaluate the color stability of light-cured and dual-cured resin cements after artificial accelerated aging. Ten specimens (6-mm diameter and 2-mm thickness) for each of five resin cements were prepared: GC (dual-cured cement, GCem), Vb (light-cured cement, Variolink II only the base), Vbc (dual-cured cement, Variolink II base with catalyst), VV (light-cured cement, Variolink Veneer), and FR (flowable resin composite, light cured). The samples were polished and stored in an accelerated artificial aging machine for 308 hours (160 klx), with cycles of 120 minutes under light and 60 minutes in the dark. All aging was carried out in distilled water at 37°C and light irradiation at 765 W/m2. The samples were evaluated in a spectrophotometer before and after aging, and results were calculated according to CIEDE2000. The data were statistically analyzed (one-way analysis of variance and Tukey test, 95% confidence). The results of ΔE00 were statistically significant for the type of cement (p&lt;0.001), with differences among tested groups. Variolink II (base only and base + catalyst) and the flowable resin were the cements with the lowest color variations after the artificial accelerated aging. Considering the values ΔE00 of acceptability and perceptibility, none of the tested cements showed acceptable values.

Legal Assurance and Legal Protection in Land Registration in Indonesia
Authors: Suharyono Suharyono 
Published: January 2019

Legal assurance to protect the owner of the land title has been the main objectives of the 1997 Government Regulation No. 24. However, in reality, the objectives above cannot be spelled due to the negative publication system of land title registration regulated by the regulation above. The loophole the system has, inter alia, concerns with the actual or the correctness of land site or the physical data of the land. As a result, a conflict will not be prevented between or amongst the true land deed holder, land rights holder and the third party. If the case is brought before the court, the further consequence is that the verdict will declare the cancelation of or invalidity of the land deed. Then the legal status of the land deed will become uncertain and landowners will lose their rights without getting any protection from the State. The problem raised in this article regarding the negative system of land registration in the 1997 government regulation no. 24 does not provide legal protection for the landowner who has already land certificate. The results of the study showed that there were two different values of legal certainty and legal protection manifested in the Government Regulation No. 24 of 1997 and those of legal certainty and legal protection as mandated by the 1945 Constitution of the Republic of Indonesia. Therefore it is not superfluous to state that legal certainty and legal protection are intended and regulated by Government Regulation No.24 of 1997 which is in contradictory to the manifested value of legal certainty and legal protection guaranteed by the 1945 Constitution
