The Relationship

Background: The mandibular third molar is the most common tooth to become impacted than other teeth, often causing more complications in the process of growing, influence to the lives of patients. Removal of wisdom teeth is one of the most common dental surgical procedures, is an invasive intervention caused significant injury to the bone and soft tissue, so hard to avoid possible complications after surgery. Understand the relationship between degree of impaction and healing after mandibular wisdom tooth surgery will bring many benefits to surgeons and patients. The purpose of this study is to evaluate the degree of impaction of mandibular third molar and explore the relationship between healing after mandibular wisdom tooth surgery with the degree of impaction. Materials and method: The study consisted of 40 patients, average age 29.38 ± 9.8 a impacted mandibular third molar and cause complications, tooth extraction is indicated. All are to be attended to, determine the degree of impaction, wisdom tooth surgery. Evaluate the healing through pain, swelling, limited mouth open after 2 days, 1 week and 2 weeks. Result: Correlation of wisdom teeth to ramus and adjacent teeth mainly type I (45%) and type II (35%), type III accounted for the lowest rates (20%). Relative depth of wisdom teeth in the bone mainly position A (45%), B position also accounts for a significant proportion (35%), positions C (20%). Correlation of wisdom teeth axis to adjacent teeth: mesioangular impactions (50%) and horizontal (30%), distoangular impaction (2.5% and 5%), vertical impaction (12, 5%). Pain, swelling, limited mouth open only happen the first two days in groups I and II, group III of symptoms until a week after surgery. Conclusion: There is correlation between the degree of impaction and healing after mandibular wisdom tooth surgery. Degree of as much impaction, the level of pain, swelling, limited mouth open higher. Key words: mandibular third molar; impaction

The Mean

The aim of this study was to describe the characteristics and types of the impacted mandibular third molar at the highest risk for pain and pericoronitis using clinical and radiographic analysis. A total of 239 volunteers, including 147 (61.5 %) male and 92 (38.5%) female patients presenting with acute pericoronitis, participated in the study. The mean age of the participants was 28 years (range 16-40 years). The analysis of type, angulations and eruption level of the mandibular third molar were achieved by using I.O.P.A. X-ray and in few cases, lateral oblique of mandible. While mesioangular impaction was the most frequent angulation (44.4%), horizontal impaction was quite less (11%). Vertical impaction (27.6%) was slightly higher than distoangular impaction (15.9%) and aberrant (0.8 %).

The Relationship

Inferior alveolar nerve injury is the main complication in mandibular third molar surgery. In this context, cone-beam computed tomography (CBCT) has become of crucial importance in evaluating the relationship between mandibular third molar and inferior alveolar nerve. Due to the growing interest in preoperative planning in oral surgery, several post-processing techniques have been implemented to obtain three-dimensional reconstructions of a volume of interest. In the present study, segmentation techniques were retrospectively applied to CBCT images in order to evaluate whether post-processing could offer better visualization of the structures of interest. Forty CBCT examinations performed for inferior third molar impaction were analyzed. Segmentation and volumetric reconstructions were performed. A dataset composed of multiplanar reconstructions for each study case, including segmented images, was submitted for evaluation to two oral surgeons, two general practitioners and four residents in oral surgery. The visualization of root morphology, canal course, and the relationship with mandibular cortical bone on both native CBCT and segmented images were assessed. Inter-rater agreement showed values of intraclass correlation coefficient (ICC) above 0.8 for all the examined parameters. Oral surgeons presented higher ICC values (p < 0.05). Segmented images can improve preoperative evaluation of the third molar and its relationship with the surrounding anatomical structures compared to native CBCT images. Further evaluation is needed to validate these preliminary results.

The Relationship

ABSTRACT Objectives Exact location of the inferior alveolar nerve (IAN) bundle is very important. The aim of this study is to evaluate the relationship between the mandibular third molar and the mandibular canal by cone-beam computed tomography. Study design This was a cross-sectional study with convenience sampling. 94 mandibular CBCTs performed with CSANEX 3D machine (Soredex, Finland) and 3D system chosen. Vertical and horizontal relationship between the mandibular canal and the third molar depicted by 3D, panoramic reformat view of CBCT and cross-sectional view. Cross-sectional view was our gold standard and other view evaluated by it. Results There were significant differences between the vertical and horizontal relation of nerve and tooth in all views (p < 0.001). Conclusion The results showed differences in the position of the inferior alveolar nerve with different views of CBCT, so CBCT images are not quite reliable and have possibility of error.
