Inferior Alveolar Nerve Injury

BACKGROUND A serious complication of surgical removal of impacted lower third molars is inferior alveolar nerve (IAN) injury. Evaluation of radiographic factors to predict IAN injury using CT and panoramic radiography includes root morphology assessment, follicular sac size, mandibular bone density, inferior alveolar nerve and vessels, condition of the overlying tissues, relation of the impacted tooth with the body and ramus of the mandible and the adjacent teeth. This study was done to evaluate the radiological features of the impacted lower mandibular teeth and their relationship with IAN through panoramic radiography and CT and to assess the most predictable radiological criteria for inferior alveolar nerve injury in impacted third molar surgery. METHODS All the patients indicated for lower third molar extraction were included in the study and pre-operative conventional panoramic radiographs (Planmeca Proline PM 2002 CC, Helsinki, Finland) and CBCT (Kodak CBCT) were taken. Any post-operative nerve injuries detected were followed up after 15 days or 1 month. Fisher’s exact test was done to find the association between the outcome variable and explanatory variables. RESULTS Only 11.4 % (N = 4) of all participants had IAN injury following surgical disimpaction. All the participants with IAN injury showed narrowing of the canal on their preoperative panoramic radiographs and presence of nerve approximation with the tooth in cone beam computed tomography (CBCT) reports (P < 0.05). CONCLUSIONS A statistically significant association exists between IAN injury and nerve exposure, radiographic signs of nerve involvement for panoramic radiograph, level of third molar impaction, and nerve approximation in CBCT.

The Relationship

Background: Clinicians should assess and monitor mandibular canal (MC) to achieve an uneventful and successful final result. Two dimensional techniques like panoramic radiography, intra oral periapical radiographs are commonly used for assessment of MC, along with three dimensional techniques like cone beam computed tomography (CBCT).Objectives: To assess the radiologic modalities and assessment criteria used by clinically practicing dental surgeons when determining the proximity of MC to third molars.Method: A questionnaire based study was carried out among national and international oral maxillofacial surgeons and general dental practitioners. Data were fed to SPSS software version 21 for descriptive statistics.Result: Most of the participants (54.7%) in the study preferred combination of panoramic radiograph and CBCT for determining the relationship of mandibular canal and third molars measures.Conclusion: Initial screening can be carried out using panoramic radiograph which is a popular method in determining the relation between the third molar and mandibular canal in spite of some limitations. Cone Beam Computed Tomography is an important three-dimensional imaging technique which is a preferred method amongst most dental surgeons.Journal of BP Koirala Institute of Health Sciences, Vol. 1, No. 1, 2018, page: 44-50
