Background: Errors of horizontal condylar inclinations and Bennett angles had largely affected the articulation of teeth and the pathways of cusps. The aim of this study was to estimate and compare between the horizontal condylar (protrusive) angles and Bennett angles of full mouth rehabilitation patients using two different articulator systems. Materials and Methods: Protrusive angles and Bennett angles of 50 adult males and females Iraqi TMD-free full mouth rehabilitation patients were estimated by using two different articulator systems. Arbitrary hinge axis location followed by protrusive angles and Bennett angles, estimation was done by a semiadjustable articulator system. A fully adjustable articulator system was utilized to locate the terminal hinge axis using a kinematic face bow followed by protrusive angles location by the aid of two square shaped transparent hard plastic protractors attached close to the condylar stylus of the articulator followed by Bennett angles calculation according to the Hanau formula. All results were subjected to statistical analyses. Results: The two articulator systems scored protrusive angles for male patients greater than female patients which were non-significant for the fully adjustable articulator but they were significant for the semiadjustable articulator. Non-significance existed between females of the fully adjustable articulator and males of the semiadjustable articulator while high significance was located between males of the fully adjustable articulator and females of the semiadjustable articulator. Concerning Bennett angles, the highest mean value belonged to the male group of the fully adjustable articulator, while the lowest scored by the female group of the semiadjustable articulator. Highly significant differences were located between the Bennett angle mean values of the groups. Conclusion: Using both articulators, the total mean values of the males were greater than the females regarding both horizontal condylar angles and Bennett angles with the total means scored by the fully adjustable articulator being larger than those of the semi-adjustable type. Using both articulators, the males' right and left condyles exhibited greater Bennett angles than their female equivalents. The precision estimation of the horizontal condylar angles and Bennett angles provided by the condylar axis protractors of the fully adjustable articulator render such type of articulators most suitable for treating full mouth rehabilitation cases. Keywords: Horizontal codylar angles, Bennett angles, two articulator systems.
The increasing level of residents’ requirements of the local community led to the necessity for sufficient local funding to satisfy the residents’ requirements and services of the local units affiliated with the decentralized administrative systems on the one hand, and to the role of local financing in the financial independence of local units on the other hand.With the presence of local financing, the financial independence of local units is achieved and is considered one of the conditions for financial independence, which is the provision of local financing to the units away from central support. The study focused in this research to clarify the concept of local financing for local units with a statement of its conditions and importan

The population contains two subclasses: susceptible and infectious, while the infectious are divided into three subgroups: Those infected by AIDS disease, HCV disease, and by both diseases. A nonlinear mathematical model for AIDS and HCV diseases is Suggested and analyzed. Both local and global stability for each feasible equilibrium point are determined theoretically by using the stability theory of differential equations, Routh-Hurwitz and Gershgorin theorem. Moreover, the numerical simulation was carried out on the model parameters in order to determine their impact on the disease

Materials and methods: Sixty extracted teeth were used, after access opening was done, the occlusal surface was flattened to create stable reference point. The teeth were randomly divided into two equal main groups of flared and unflared group each one of 30 teeth. The flaring was done with Gates Glidden drills. The two main groups were further subdivided into two subgroups: dry canal and wet canal using 5.25% sodium hypochlorite groups, Electronic WL of each sample was determined using both Root ZX and i-Root apex locator. Consequently, histologic WL was determined by shav

Many intracellular enzymes like (alkaline phosphatase- (ALP), aspartate aminotransferase- (AST) and alanine aminotransferase- (ALT) that are released outside cells into the gingival crevicular fluid (GCF) and saliva after destruction of periodontal tissue during periodontitis. This study was conducted to determine the periodontal health status and the levels of salivary enzymes (ALP, AST and ALT) of the study and control groups and to correlate the levels of these enzymes with clinical periodontal parameters in each study group. Subjects, Materials and Methods: One hundred subjects were enrolled in the study, with a

Show MoreThe trichomes and chemical composition of three species of the genus Salvia wild-grown (Salvia lanigera, Salvia spinosa) and cultured (Salvia officinalis) were studied in the Anbar governate, the chemical components of the stem and leaves were studied by Gas chromatography–mass spectrometry(GC-MS), in addition to studying the trichomes of the epidermis in the stem and leaves (upper and lower epidermis) by Light microscope. Important differences appeared to us in the chemical study, where it was found that some compounds were found in species without others, which gives them taxonomic importance, also, the trichomes were important in distinguishing the studied species, the species S. spinosa was distinguished by the presence of gla
