Radiologic Evaluation

Background: Odontometric and osteologic trait have always served as an excellent resource in anthropological, genetic, odontologic, and forensic investigations. Traits: The aim of this study was to find the most reliable method for gender determination by correlating both the odontometric and osteologic variables. Materials and Methods: A retrospective study was conducted using digital panoramic radiographs of 400 individuals (200 males and 200 females) with age ranging from 20 to 50 years. Standardized digital panoramic radiographs of patients taken as part of pretreatment planning for implants, extractions of third molars, and for periodontal diseases were selected from the archives. Measurements were done using IMAGE Pro software. Results: Mesiodistal width of 17–47 exhibited significant gender variation. Osteologic parameters such as ramus dimension and the gonial angle also showed significant gender variation and the mandibular asymmetry was significant in both the genders. Conclusion: Correlation of the two group of traits showed strong positive predictive values attributable for gender determination.

SummaryBackground/Aim: Gender determination is one of the most challenging tasks in medico-legal research and forensic dentistry. Several skeletal components are investigated for this purpose and the mandible is one of them. The mandible has several specific anatomical features. The purpose of this study was to analyze the effects of measurements related to the mental foramen, gonial angle and antegonial angle on gender determination using digital panoramic radiographs.Material and Methods: A retrospective study was planned with 150 digital panoramic radiographs (75 males and 75 females, aged between 20 to 49 years). The radiographs were analyzed by dividing them into two equal gender groups (male and female). Several parameters were compared to determine the gender. The distances from the superior and inferior border of the mental foramen to the basis of the mandible on the right side were measured. Gonial and antegonial angles were evaluated bilaterally. The difference between the males and females were analyzed with independent samples t-test (p<0.05).Results: There was statistically significant difference between the males and females in terms of all the evaluated parameters (p<0.05). The distances related to mental foramen is higher in the males however gonial and antegonial angles are larger in the females.Conclusions: The mental foramen position, gonial and antegonial angles can be used to predict the gender in Turkish population.

Abstract Objectives The aim was to evaluate the characteristics of the mandibular third molars, especially in relation to the inferior alveolar nerve. Further aims were to investigate incidental findings in panoramic radiographs in an adult population, and to investigate image quality related to patient positioning. Materials and Methods From a previous study with 451 randomly selected adult participants who lived in Sweden, 442 panoramic radiographs from four dental public health clinics were used. The third molars’ characteristics and relation to inferior alveolar nerve were evaluated. Incidental findings and patient positioning were recorded. Statistical Analysis Frequency analysis was used to investigate the occurrence of all findings and their possible interconnections. Whether the patients’ age or gender had an impact or not was also analyzed. Results The third molars were erupted in vertical position among 73% regardless of age. When retained or semi-retained, they were most commonly in mesioangular positions. The inferior alveolar nerve was located inferior to the roots in 52%, whereas an overlapped position was most common if the third molar was retained (90%), semi-retained (83%) or the age was less than 30 years (66%). Common incidental findings were apical radiolucencies, idiopathic osteosclerosis, and tooth fragments. Suboptimal patient positioning was found in one-third of the radiographs. Conclusions Panoramic radiography is a useful method to evaluate third molar prior to surgical removal and may be the only image required. Most incidental findings on panoramic radiographs does not seem to require any further odontological management.

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.

Abstract Panoramic radiographs of two female patients ages 22 and 21 revealed the presence of two impacted bilateral upper fourth molars and unilateral (right) upper fourth and fifth molars. All of the teeth were distomolars. The supernumerary teeth had normal tooth morphology with regard to their crowns and roots but were slightly smaller than the existing third molars. Their crowns were either two or three tuberculated and they all had single roots. Citation Kokten G, Balcioglu H, Buyukertan M. Supernumerary Fourth and Fifth Molars: A Report of Two Cases.
