تهدف هذه الدراسة إلى تحديد المشاكل الهيكلية بالمستوى السهمي عند مرضى الفقد الولادي للأسنان. في هذه الدراسة تم أخذ صور شعاعية سيفالومترية ل 96 مريضا بشرط أن يكون المرضى من أب و أم من الساحل السوري. قسمت العينة حسب الجنس و حسب موقع الفقد إلى ثلاث مجموعات: مجموعة فقد أمامي و مجموعة فقد خلفي و مجموعة فقد مشترك (أمامي-خلفي).
This study aims to determine the skeletal problems in sagittal plane in patients with congenital hypodontia. In this study, 96 cephalograms were taken of Syrian coastal father and mother. The sample was divided according to gender and to location of the missing teeth. The angles SNA, SNB and ANB were studied.

Malocclusion is considered one of the most prevalent dental problems .This research aimed to study the prevalence of malocclusion states in the Syrian coast community.
The sample of study consists of 1200 patients in mixed dentition stage (569 male
s – 631 females) with mean age (8.65 ± 1.4 years for male, 8.64 ±1.36 years for females).
The study showed a prevalence of malocclusion in about 84.8% of the sample, with about 58.33% for vertical plane malocclusion and 84% for sagittal plane malocclusion, and 37.8% for transversal plane malocclusion.
We concluded that it is very important to improve the hygiene awareness between our community population for better prevention and treatment of these problems.
The aim of this study was to investigate the relationship
between cervical vertebral posture in patients with skeletal Class II
malocclusion by using lateral cephalometric radiographs were taken
by natural head position.
The Objective is to study the relation between craniocervical
posture and skeletal patterns of malocclusion in the sagittal plane in
adults , None of them had a history of previous orthodontic or
orthognathic surgery treatment by using lateral cep
halometric
radiographs. our sample consisted of 71 adults patients; class I
(n=21) , class II (n= 30 ) , class III (n=20 ) .All radiographes were
taken in natural head position.
This study aimed to identify the impact of career management and demographic
variables on organizational commitment of employees in a number of industrial companies
in the Syrian coast, where the researcher followed the descriptive approach that fi
ts the
nature of the research, was relying on deliberate soft sample of (100) factor in the
companies mentioned, data were analyzed and test hypotheses using a computer program
SPSS 20. the researcher concluded to the following results: there is a positive and a weak
correlation between the career management and organizational commitment in the
companies under study, and this study found a positive and a weak correlation between the
(promoting, job enrichment and training) and organizational commitment, and This study
found no significant differences between the answer of respondents by sex and age,
witch mean there is no differences between male and female responses, and there is no
differences between the answer of the respondents according to age groups.
The purpose of this comparative study was to evaluate the correlation between
two radiographic methods used to evaluate skeletal maturation, hand-wrist analysis method and cervical
vertebrae analysis method.
Within the limits of this study, the ce
rvical vertebrae maturation method might mislead the
clinician when treating adolescent skeletal Class II patients at the pubertal growth spurt since it is not
correlated with hand wrist skeletal maturation method.
