من المعلوم إنه نمو الحنك عموماً هو نتيجة للتشكل العظمي للدروز الحنكية و تطاول النتوءات السنخية، إلا إنه من غير المعروف بدقة مدى العلاقة المتبادلة ما بين عمليتي النمو هاتين، و بين عمق و طول قبة الحنك الصلب، من هنا فإنه يتوجب على الإختصاصيين اللجوء إلى تقييم قبة الحنك الصلب قابل للقياس مما يسمح بوضع تشخيص أكثر دقة و يساعد الممارس في تقييم أفضل لهذه البنية التشريحية. هدف البحث: دراسة العلاقة بين طول و عمق قبة الحنك الصلب مع النمو الوجهي و ذلك لدى أفراد من البالغين باستخدام التصوير الطبقي المخروطي.
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 unsolved. 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.

Research summary
تهدف هذه الدراسة إلى التحقيق في العلاقة بين طول وعمق قبة الحنك الصلب ونمو الوجه لدى المراهقين باستخدام التصوير الطبقي المحوري المخروطي (CBCT). شملت الدراسة 20 مريضًا قوقازيًا (8 ذكور و12 إناث) تتراوح أعمارهم بين 18 و23 عامًا. تم إجراء دراسة سبفالومترية للنمو الوجهي وفقًا لطريقة جاراباك، وتم حساب معامل ارتباط بيرسون لدراسة العلاقة بين طول وعمق قبة الحنك الصلب ونمو الوجه. أظهرت النتائج أنه لا توجد فروقات ذات دلالة إحصائية بين الجنسين في قياسات قبة الحنك الصلب، وأن طول وعمق قبة الحنك الصلب لا يرتبطان بنمو الوجه. خلصت الدراسة إلى أن طول وعمق قبة الحنك الصلب لا يتبعان أي نمط نمو وجهي محدد.
Critical review
دراسة نقدية: تُعد هذه الدراسة مهمة في مجال تقويم الأسنان والفكين، حيث تسلط الضوء على العلاقة بين قبة الحنك الصلب ونمو الوجه. ومع ذلك، يمكن انتقاد الدراسة من عدة جوانب. أولاً، حجم العينة صغير نسبياً (20 مريضًا فقط)، مما قد يؤثر على تعميم النتائج. ثانيًا، اقتصرت الدراسة على العرق القوقازي فقط، مما يقلل من تنوع العينة ويجعل من الصعب تعميم النتائج على مجموعات عرقية أخرى. ثالثًا، لم تأخذ الدراسة في الاعتبار العوامل البيئية والجينية الأخرى التي قد تؤثر على نمو الوجه وقبة الحنك. وأخيرًا، كان من الممكن أن تكون الدراسة أقوى إذا تم تضمين مجموعة مقارنة من المرضى الذين يعانون من مشاكل تقويمية أو أمراض الأنف والأذن والحنجرة.

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 diff
erent 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.
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 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.
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 aim of this research is to investigate the dimensional and positional symmetries
between the right and left condyles ,and the possible asymmetries between the condylar
processes that could be related to the type of growth pattern in adult subje
cts with no
clinical nor radiographic symptoms of TMDs.
Materials and methods: In result of a multistage clinical examination protocol, 14
Caucasian patients with normal growth pattern ,and with no prior orthodontics treatment
were selected (14 females)from 17 to 29 years of age with no clinical signs and symptoms
of TMDs.
The images obtained from the axial and sagittal slices, Cephalometric growth pattern
study was performed. Pearson's Correlation Coefficient and T-test were calculated.
Results :no statistically significant relationship between the measurements of
TMJ(left &right) and the normal growth pattern.
Conclusions:There is no relationship between the morphology of TMJ and normal
growth pattern in adult female orthodontically non-treated .
