تهدف هذه الدراسة إلى معرفة تأثير الجنس على سماكة النسج الرخوة للذقن في الأنماط المختلفة لدوران الفك السفلي (أمامي- طبيعي – خلفي). تتألف العينة من 100 صورة شعاعية سيفالومترية جانبية لـ (69 أنثى _ 31 ذكر) بالغين, و قد تم انتقاؤهم وفق الشروط التالية : العمر بين 18 -26 سنة , استبعاد جميع حالات الشذوذات الاطباقية الشديدة , الإطباق دائم و لايوجود شذوذات شكلية بالأسنان دون أخذ الأرحاء الثالثة بعين الاعتبار , عدم وجود معالجة تقويمية سابقة , خلو المريض من الأمراض الجهازية أو التشوهات الخلقية, عدم وجود أي قصة جراحية سابقة في منطقة الرأس و العنق تم تقسيم العينة إلى مجموعات حسب الجنس و الدوران الفكي السفلي (أمامي- طبيعي – خلفي) ثم دراسة مجموعة من المتغيرات الممثلة للدوران الفك السفلي و أخرى ممثلة لقياسات الأنسجة الخوة للذقن. و قد أظهرت النتائج اختلاف متوسطات مقاييس ثخانة الأنسجة الرخوة و مؤشرات دوران الفك السفلي بين الجنسين لصالح الذكور, كما أن المتوسطات الحسابية أظهرت ارتباطاً بين متغيرات سماكة النسج الرخوة للذقن عند الإناث مع الأنواع الثلاثة لدوران الفك السفلي مقارنةً مع الذكور.
The aime of this study was to determinethe effect of gender on the soft tissue of the chin at each type of rotation patterns of the lower jaw (Anterior - normal - Posterior) The sample consisted of 100 X-ray Lateral cephalometric radiographs of (69 female _ 31 male) adults, has been selected according to the following conditions: Age between 18-26 years old, , exclusion of all cases of Intenseocclusal abnormalities , Permanentocclusionand there is noformaldentalabnormalitieswithout takinginto accountthe thirdmolars, The absence ofa previousorthodontic treatment, the patient free fromsystemic diseasesorcongenital malformationsanddevelopmentaldisordersandsyndromesand there is no story of a previous surgery in the head and neck area The sample was divided into groups according tosex andmandibularrotation(Anterior - normal - Posterior). Then we studied variablesrepresentative the lower jaw rotation andanother ones representativethemeasurementsof the chinsoft tissue. The results showed a difference theaveragesof the soft tissue thickness and the indicators of mandible rotation between the sexes In favor of males, And theaveragesof thevariables showed Correlationbetween chinsofttissuethicknessin femaleswiththree typesoflower jawrotation Compared with males.

The aim of the study was to evaluate The relation between morphology of lips and incisors and mandibular rotation in adult class Ι individuals and to explore the gender dimorphism for these measurments. Material and methods True lateral cephalometri
c radiograph of the sample that comprises 32 females and 30 males aged 18-25 years and they possess class I skeletally and dentally. The data were analyzed using independent sample t test and Pearson correlation analysis. Results: In males interlabial angle negatively correlated with U1-NS and positively with U1-L1 Nasolabial angle and mentolabial angle positively correlated with (NS-GoMe, FH-GoMe, B, Bijork angles) Zangle and ULT/ULH negatively correlated with (NS-GoMe, FH-GoMe, B, Bijork angles) in Females lower lip inclination positively correlated with (NS-GoMe, FH-GoMe, B, Bijork angles).
The aim of this study was to identify the configuration of the mandibular canal
radiographically in the vertical direction on Digital Panoramic Radiographs to evaluate the relationship
of the mandibular canal with the Status of the third mandibular Molar which will add important
diagnostic radiographic signs specially before performing extraction of the mandibular 3rd molar .
The study included 480 patients , 260 males and 220 females who have 920
teeth to beextracted.
The ages of patients were ranging from 20 to 40 years.
In each group the teeth were divided according to its location , Mandible,
Maxillary, anterior o
r posterior.
The extractions were symmetric .Socketol was used in one side while was
not used in the other side..
Patients were recalled after 24 hours 36 hours,48 hours and 72 hours .
Dry socket was determined by the symptoms and signs.
It was found in this research that the seismic response of the
structure increases with the decrease in the shear waves velocity in
the soil, and the seismic response of the structure increases with
soil layer thickness between the foundations of the structure and
bedrock depth.
This study aimed to compare the dimensions of soft facial tissues
between the open bite and deep bite malocclusion cases, in
patients with sagittally Class I occlusion.
