IMF serves as a cornerstone during surgeries related to reconstruction orthognathic and facial trauma surgery. Successful treatment of mandibular fractures depends on reduction and restoration of normal occlusion and immobilization. So this study attempts to evaluate dental root damage through intermaxillary fixation with pre-drilled bone screws in the management of non-displacement or mini-displacement mandibular fractures. Complications were observed clinically and radiologically to evaluate the damage and loss vital to the adjacent tooth root. Data were subjected to statistical analysis using Chi Square Test. P-Value<0.05 was considered significant .This study found out that the intermaxillary fixation screws proved to be a safe technique to the intermaxillary fixation; however, it is not without complications or potential consequences which the surgeon must be aware of in order to provide safe and effective treatment.

Research summary
تهدف هذه الدراسة إلى تقييم أذية الجذر السني في سياق التثبيت بين الفكين باستخدام براغي pre-drilled في معالجة كسور الفك السفلي غير المتبدلة أو ذات التبدل البسيط. تم إجراء الدراسة على 20 مريضًا (19 ذكر و1 أنثى) تتراوح أعمارهم بين 12-48 عامًا، وتمت مراقبتهم سريريًا وشعاعيًا لمدة 3 أشهر بعد الجراحة. تم استخدام براغي التثبيت بين الفكين من نوع pre-drilled bone screws كورية الصنع من إنتاج شركة osstem. أظهرت النتائج أن نسبة أذية الجذر السني كانت 3.1% من مجموع البراغي المستخدمة، ولم يحدث فقد حيوية السن المتأذي جذره في أي من الحالات. خلصت الدراسة إلى أن تقنية التثبيت بين الفكين باستخدام براغي pre-drilled هي طريقة آمنة، لكنها لا تخلو من الاختلاطات التي يجب أن يكون الجراح واعيًا لها للحصول على معالجة آمنة وفعالة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال جراحة الفم والفكين، حيث تقدم تقييمًا دقيقًا لأذية الجذر السني في سياق التثبيت بين الفكين باستخدام براغي pre-drilled. ومع ذلك، يمكن أن تكون هناك بعض النقاط التي تحتاج إلى تحسين. على سبيل المثال، كان حجم العينة صغيرًا نسبيًا (20 مريضًا فقط)، مما قد يؤثر على تعميم النتائج. كما أن الدراسة لم تتطرق بشكل كافٍ إلى مقارنة فعالية البراغي pre-drilled مع أنواع أخرى من البراغي مثل self-drilling screws. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تم تضمين متغيرات أخرى مثل مدة الشفاء والتكلفة والراحة للمريض. على الرغم من هذه النقاط، فإن الدراسة تقدم مساهمة قيمة في فهم أذية الجذر السني وتقديم توصيات لتحسين الممارسات الجراحية.
Questions related to the research
  1. ما هو الهدف الرئيسي من الدراسة؟

    الهدف الرئيسي من الدراسة هو تقييم أذية الجذر السني في سياق التثبيت بين الفكين باستخدام براغي pre-drilled في معالجة كسور الفك السفلي غير المتبدلة أو ذات التبدل البسيط.

  2. ما هي نسبة حدوث أذية الجذر السني وفقًا لنتائج الدراسة؟

    أظهرت النتائج أن نسبة حدوث أذية الجذر السني كانت 3.1% من مجموع البراغي المستخدمة.

  3. ما هي التوصيات التي قدمتها الدراسة؟

    أوصت الدراسة باستخدام براغي التثبيت بين الفكين IMF screws في معالجة كسور الفك السفلي غير المتبدلة أو ذات التبدل البسيط، وأكدت على أهمية استخدام وسائل تشخيصية دقيقة لتحديد الأماكن الملائمة لإدخال البراغي.

  4. ما هي الاختلافات بين هذه الدراسة والدراسات السابقة؟

    أظهرت هذه الدراسة نسبة أذية جذر السني بلغت 3.1%، بينما سجلت دراسات سابقة نسبًا مختلفة، مثل دراسة Roccia et al (2005) التي سجلت نسبة 5.5%، ودراسة Ueki et al (2007) التي لم تسجل أي أذية. يعود هذا الاختلاف إلى نوع البراغي المستخدمة في كل دراسة.

The purpose of this study was to evaluate the reliability of a single malleable noncommpression titanium miniplate in fixation and stability of fractures of the mandibular angle using two approaches(.transbuccal and intra-oral approach, or intra-or ally alone) . The research sample included 20 patients from patients who attended AL Assad University Hospital with Unilateral or bilateralun-comminuted mandibular angle fractures in the period between September 2011 and October 2013. The research sample was divided into two groups depending on the two approaches that have been used . Adequacy of the reduction and stability of fixation were evaluated through Radiographic examinations immediately after surgery. Postoperative assessment was based on clinical examination after 1 month, 6 monthes and a year to evaluate: Occlusion, Masticatory efficiency, Maximum mouth opening range, and Other complications(infection –mini-plate exposure). The results of the present study showed that there were statistical difference between the two approaches(transbuccal and intra-oral approach, or intra-orally alone) regarding Occlusion, Masticatory efficiency and Other complications after 1 and 6 months while there was no statistical difference between the approaches after 1 year . we Concluded that using the combined transbuccal/oral approach was the best regarding(infection and mini-plate exposure) and compared with intra-oral approach .
Closed reduction and percutaneous pin fixation is considered standard management for displaced supracondylar fractures of the humerus in children. However, controversy exists regarding whether to use pins from the lateral side or medial and latera l side of the elbow for fixation . We performed this research to know the results of two ways of treatment and to compare : 1- the risk of iatrogenic ulnar nerve injury caused by pin fixation . 2- quality of fracture reduction in terms of radiographic outcomes . 3- compare function of the elbow and other surgical complications caused by pin fixation between two ways.
Fractures of the mandibular condyles are frequent in facial traumas and their treatment represents a highly controversial issue in maxillofacial traumatology, functional and surgical treatments being the two principal management modalities for such f ractures. The aim of this study is to evaluate the results of functional treatment of mandibular condylar fractures in patients which received this type of treatment. Eighty-six patients between 6 and 66 years old who were previously treated fuctionally for a fracture of the mandible condyle were recalled for follow up examination with a mean postoperative observation time of 10.4 years. Mandibular function was assessed using the mandibular function impairment questionnaire and patient's complaints were assessed during physical examination. The results showed a significant increase of dysfunction index values with increasing age at the time of trauma. Radiologic abnormalities such as reduced ramus height, deviation of the mandibular midline, and irregular shape of the condyle were observed and seen frequently, but they were not correlated with the severity of dysfunction. Predictors of mandibular function impairment after closed treatment of fractures of the mandibular condyle were: great deviation, reduced mouth opening, women gender, and increased age. The results of this study support the opinion that functional treatment is sufficient in pediatric patients, whereas in older age groups the results of conservative treatment are less sufficient
The purpose of the present study was to radiologically assess the hard tissue changes around the immediately loaded implants single tooth bioactivated with plasma rich in growth factors ,placed in the mandibular posterior region . Twenty dental im plants placed in 13 patients had at least single edentulous space in the posterior region of the mandible using single stage procedure after bioactivation the implants surfaces with plasma rich in growth factors.
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).
