خلفية و هدف البحث: يعد غياب الأسنان من الشذوذات التطورية لدى الأسنان و تترافق هذه الحالات بمشكلات تقويمية متعددة، و غالباً ما تختلف المعالجة بحسب الأسنان المفقودة، و عددها. إن هدف البحث مقارنة حجوم الأسنان الأمامية عند مرضى فقد الرباعيات العلوية أحادي و ثنائي الجانب بالنسب الطبيعية لحجوم الأسنان في مدينة دمشق.
Background& Objective: The purpose of this study is to compare the anterior tooth size width in patients with congenitally missing maxillary lateral incisors with the normal width size of the Syrian.

To record the prevalence and distribution of congenitally missing permanent
teeth and their relation to gender in a sample of patients in an orthodontic clinic in Damascus.
the purpose of this study to evaluate early implant success of small-diameter
2.5mm one-stage dental implants immediately loading in congenital missing of maxillary lateral incisor
cases associated with limited interdental space and mesial and distal bone loss after one year of loading.
Aim: This study aims to investigate the relationship between the cephalometric soft tissue parameters value of the facial profile before the start of applying of en masse retraction of Maxillary Anterior teeth (after 14 and 24 extraction) and the dam
ping of the applied orthodontic force v after 40 days of its application. Materials and Methods: material research consist from cephalograms of six patients (3 females and 3 males) between 17 and 19 years from patients undergoing orthodontic evaluation at the Department of Orthodontics and Dentofacial Orthopedics at Tishreen University , ortho. Plane treatment of those patient included 14 and 24 extraction in order to reduce the big sagital overjet by bodily en masse retraction of Maxillary Anterior teeth to achieve o aesthetic harmony of the soft tissues of the facial profile of each one of these particular patients. Pearson's Correlation Coefficient Analysis was performed. The Correlation was verified between each cephalometric variables (both those related to the soft tissue of the facial profile and to the variables determining incisors and the upper first molars axes inclination) on the one hand and between the amount of force at the beginning of the movement (F1) and the amount of force after forty Day of starting application of force (F2), and the amount of force damping (F1 - F2), and the distance that have been closed due to the b bodily en masse retraction of Maxillary Anterior teeth during 40 days. This study showed a certain relationship between the primary values of the soft tissue variables of the facial profile and the force damping applied to achieve bodily en masse retraction of Maxillary Anterior teeth.
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.
The aim of this study was to investigate the role of teeth sizes
and its relationship with the development of buccal ectopia
for maxillary canines،that could contribute to the aetiology of
canines ectopia ,between males and females in the sample o
f
Syrian society.
The study models have been obtained, the mesiodistal width
was measured for all upper and lower teeth except of second
and third molars by using electronic caliper, data collected
then analyzed and got results.
