Many of researchers concerned jaws bases dimensions because of it's a part of craniofacial complex , its influence on the facial aestheticand functional portions .Though these dimensions were studied by Björk the width of the jaws bases in the different planes, its relation with craniofacial growth and development had been not studied . Aim: The aim of this study is to investigate the relationship of the length and width of the jaws in the frontal plane with Facial Growth Type in adults using Cone-Beam Computed Tomography scan (CBCT). Materials and methods: 33 adult patients (22 female, 11 male) with no prior orthodontic treatment were selected with age average 16 - 27 years ( mean age of 20.02 years, females average age was 20.15 years ; males average age was 21.84 years ) of age , were ordinary undergoing CBCT scan for non-orthodontics purpose. Cephalometric measurements determining facial growth type were performed according to Jarabak'sanalysis. Pearson's Correlation Coefficient was calculated to investigate the relationship between the CBCT jaws measurements and facial growth type according to Jarabak's analysis. Results :CBCT measurements of jaws' dimensions in the frontal plane showed no statistical significant differences. Conclusion:There is no relationship between jaws bases' dimensions in the frontal plane and facial growth pattern in adults orthodontic ally non-treated subjects.

Research summary
تتناول هذه الدراسة العلاقة بين أبعاد القواعد الفكية في المستوى الجبهي ونماذج النمو الوجهي لدى البالغين غير المعالجين تقويمياً باستخدام التصوير الشعاعي الطبقي المحوري المخروطي (CBCT). شملت العينة 33 مريضاً بالغاً (22 أنثى و11 ذكر) لم يخضعوا لعلاج تقويمي سابق. تم تحليل نماذج النمو الوجهي باستخدام تحليل جاراباك، وتم حساب معامل ارتباط بيرسون لدراسة العلاقة بين قياسات القواعد الفكية ونماذج النمو الوجهي. أظهرت النتائج عدم وجود فروقات ذات دلالة إحصائية في قياسات القواعد الفكية في المستوى الجبهي بين مختلف نماذج النمو الوجهي. خلصت الدراسة إلى عدم وجود علاقة بين أبعاد القواعد الفكية في المستوى الجبهي ونموذج النمو الوجهي لدى المرضى البالغين غير المعالجين تقويمياً.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لأنها تستخدم التصوير الشعاعي الطبقي المحوري المخروطي (CBCT) الذي يوفر دقة عالية في قياس الأبعاد الثلاثية للبنى التشريحية. ومع ذلك، يمكن توجيه بعض النقد للدراسة. أولاً، حجم العينة صغير نسبياً (33 مريضاً)، مما قد يؤثر على قوة النتائج وإمكانية تعميمها. ثانياً، لم تأخذ الدراسة في الاعتبار العوامل الأخرى التي قد تؤثر على أبعاد القواعد الفكية مثل العوامل الوراثية والبيئية. ثالثاً، اقتصرت الدراسة على البالغين غير المعالجين تقويمياً، مما يحد من إمكانية تطبيق النتائج على فئات أخرى من المرضى. وأخيراً، قد يكون من المفيد إجراء دراسات مستقبلية تشمل عينات أكبر وتأخذ في الاعتبار العوامل المتعددة التي قد تؤثر على أبعاد القواعد الفكية.

It is generally agreed that growth in palatine results from bone formation at the palatine sutures and lengthening of the alveolar processes, but the extent to which these two sites contribute to the depth and length of the hard palate remains unso lved. Hence, professionals should use quantitative assessments of the hard palate, which allow more accuracy in the diagnosis and assessment of this structure. Aim investigating the relationship between the length and depth of the skeletal hard palatine with facial growth type in adult subjects using CBCT scan.
The dentoalveolar mechanism, within the dentofacial complex, acts to camouflage the vertical base bone discrepancies resulting in differences in the functional occlusal plane cant (FOPC). Considering this, ensures more stable orthodontic treatment re sults. This research aims to study the possibility of a relationship between the FOPC (represented by anterior and posterior occlusal planes) and the vertical facial growth patterns (VFGPs) using cone beam computed tomography (CBCT). The research sample consisted of 50 CBCTs (22 males and 28 females) aged 18 to 35 years with no prior orthodontic treatments. Their FOPCs were studied according to the VFGPs. Pearson's correlation coefficient was then calculated for all the data obtained. The study showed that the posterior occlusal plane has a clearer correlation to the VFGPs than to the traditional occlusal plane. The posterior occlusal plane showed a strong correlation with the VFGPs in the female sample.
Facial structures, as well as their functions and correlations, have been extensively studied to expand the knowledge of craniofacial growth and development and to optimize growth predictions and proper indications of orthodontic and surgical treat ments. The cranial base forms the boundaries of the craniofacial complex . The nasomaxillary complex is related to the anterior cranial base, whereas the mandible is related to its posterior portion. Therefore, the shape of the cranial base is an important factor in establishing the position of the maxilla and mandible. Aim: to investigate the relationship of cranial base with jaws rotation in adult orthodontically non-treated subjects using Cone- Beam Computed Tomography (CBCT) scan. Materials and methods: 27 Caucasian adult patients with no prior orthodontics treatment were selected (16 males, 11 females) .Cephalometric measurements determining type of jaw rotation were performed according to Björk's analysis. Pearson's Correlation Coefficient was calculated to investigate the relationship between the CBCT cranial base measurements and Cephalometric measurements determining type of jaw rotation . Results: This study reveal vary correlation between CBCT measurements of cranial base's dimensions and jaws rotation. Conclusions: There is no relationship between the cranial base morphology and Jaws rotation in adult orthodontically non-treated subjects.
The research aim for testing the correlations between the morphology of the bone around the apexes of the central incisors and facial type.the sample consist of 59 patient.They were divided into three groups according to their facial Type.the result is three groups ,19 short face type, 20 norm face type, and 20 long face type patients, aged 19 to 40 years.we have measured many measurement that determine the relationship between the apex of central upper incisor and its surroundings. The measurements were processed using analysis of variance Anova and Mann-Whitney U-tests and (Correlation coefficient )r .We find that at the upper central incisors, In short face type subjects the root apex of the upper central incisors was farther away from the lingual cortex than in the norm face type and long face type. In long face type subjects the root apex of the upper incisors was farther away from the palatal plane than in the norm face type and long face type.
The asymmetric face is common so that increased interest in it . there are different ways to assess the asymmetry. Computed tomography is an accurate way that enable the examiner for reading the face at three planes ,and present three-dimensional information on the cranial mandibular Complex whereas (3D) analysis is essential for making a precise diagnosis of craniofacial morphology . Aim : This research aims to study the asymmetric at the facial patterns malocclusion (class I. Class III) using CT .
