هدفت هذه الدراسة إلى إيجاد دلالات تشخيصية شعاعية قبل إجراء قلع الأرحاء الثالثة السفلية عن طريق تحديد مسار قناة الفك السفلي في منطقة الرحى الثالثة بالمستوى العمودي على الصورة البانورامية الرقمية ، لتقييم علاقة قناة الفك السفلي مع توضع الرحى الثالثة السفلية.
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 .

Impacted mandibular third molar area has been a topic of interest for a long time, and one of the most investigated parameters for two reasons:1- the lower third molars are the second most frequently impacted teeth[1,2 ]. 2- the lack of space is cons
idered to be the major cause of this.so the radiographic diagnosis for this area is an important issue for orthodontists because of it's important role in mandibular third molar eruption wich play an impact on lower arch crowding and stability of orthodontic treatment. Objective:to study the relationship between impacted mandibular third molar area morphology and mandibular length in adults with skeletal malocclusion in the sagittal plane and to investigate the effect of sex on this area in these subjects by using cephalometric radiographic.
This study was aimed to evaluate the effect of the use of Platelet-
Rich Fibrin on immediat complication following impacted
mandibular third molar surgery. forty extractions of bilateral
impacted mandibular third molars were performed in 20 volunt
eers
(18 to 25 years old). After extraction of right and left mandibular
third molars, the socket at 1 side received the autologous PRF (test
group) and the other was filled with blood clot (control group) .
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.
Many factors such as direction of mandibular growth, early loss of
deciduous molars, the effect of maxillary and mandibular lengths
and incisor and molar inclination can be associated with crowding.
The aim of study to evaluate the effect of mandibular anterior
crowding on maxillary and mandibular base lengths and ANB
angle in the early mixed dentition .
This clinical study included 30 cases of impacted lower third molars, which were
surgically extracted at the oral surgery department at Tishreen University in Lattakia. The
ages of patients were between 20 - 30 years. The aim of this study was to e
valuate the
effect of alveolar rinse with Tetracycline and Articaine mixture on pain, edema, and
trismus after surgical extraction of impacted lower third molars.
The sample was divided into two groups:
- First Group (Study Group): /16/ impacted lower third molars were surgically
extracted. The alveolar socket was rinsed with Tetracycline and Articaine mixture
immediately after removal of the impacted molar.
- Second Group (Control Group): /14/ impacted lower third molars were surgically
extracted. The alveolar socket was rinsed with Saline immediately after removal of the
impacted molar.
The study showed that alveolar rinse with Tetracycline and Articaine mixture had a
significant effect on pain, edema, and trismus after surgical extraction of lower third
molars in comparison with Saline alveolar rinse (P<0.05).
