Comparison between conventional radiograph and 3d volumetric radiograph for determining the morphology and morphometry of mental foramen

The mental foramen is used by oral surgeons during procedures such as extractions, implant placements, osteotomies, nerve blocks, and other surgeries that might potentially harm the neurovascular bundle in the area. The purpose of this research was to evaluate the accuracy of the digitalized volumetric tomography (DVT) in detecting the brain foramen and in assessing its size, shape, and clarity in comparison to the orthopantomogram (OPG) (DVT). Materials and Method: Twenty-five people total took part in the research, with men and women represented equally. Expert three-dimensional (3D) software in DVT and Annotation software in OPG were used to compare and contrast the location, contour, size, and clarity of the cerebral foramen. Results: “The mental foramen was located in the center of the jaw, between the roots of the upper and lower molars and the super inferior cortex of the mandible. The mental foramen was found to be in the same place by both OPG and DVT. Most mental foramen were found to be oval, with the highest definition seen in DVT. DVT provided a more distinct picture of the anatomy, and measurements of the mental foramen were determined to be 0.51 0.06 cm, compared to 0.49 0.05 cm in OPG

The impact of early orthodontic intervention on dental and skeletal development in children with mixed dentition

Background: The mixed dentition stage in children is a critical period for orthodontic assessment and intervention. This study investigates the effects of interceptive orthodontics on dental and skeletal development in children with mixed dentition, aiming to evaluate the potential benefits of early orthodontic treatment. Materials and Methods: A retrospective analysis was conducted on a cohort of 150 children with mixed dentition (aged 7–11 years), who received interceptive orthodontic treatment. Dental and skeletal records, including cephalometric radiographs and dental cast models, were collected before and after treatment. A control group of 150 untreated children with mixed dentition was also assessed for comparison. Various dental and skeletal parameters, such as dental alignment, overjet (OJ), overbite (OB), and cephalometric measurements, were recorded and analyzed. Results: The results of this study indicate significant improvements in dental alignment and occlusion in the group of children who received interceptive orthodontic treatment. The average reduction in OJ was 3.5 mm, and the OB correction averaged 2.1 mm. Cephalometric analysis showed positive changes in skeletal relationships, with a mean reduction in the angle formed by point A, nasion (N) and point B. (ANB) angle of 2.8 degrees. These improvements were statistically significant compared to the control group (P < 0.05). Conclusion: Early orthodontic intervention, such as interceptive orthodontics, has a positive impact on dental and skeletal development in children with mixed dentition

Comparative evaluation of CBCT and MRI in Temporomandibular Joint (TMJ) disorders and their relationship to periodontal health

Cone beam computed tomography (CBCT) and magnetic resonance imaging (MRI) are diagnostic tools frequently employed to evaluate temporomandibular joint (TMJ) disorders, yet their comparative efficacy remains a subject of interest. In this study, we conducted a comparative evaluation of CBCT and MRI in diagnosing TMJ disorders and assessing their association with periodontal health. We recruited a sample of 100 patients presenting with TMJ symptoms and divided them into two groups. Group A underwent CBCT imaging, while Group B received MRI scans. Clinical assessments of periodontal health were performed using established periodontal indices. Diagnostic accuracy, sensitivity, specificity, and interobserver agreement were calculated for each imaging modality. In the current study, CBCT demonstrated superior diagnostic accuracy (85%) compared to MRI (72%) in identifying TMJ disorders. Sensitivity and specificity for CBCT were 87% and 83%, respectively, while for MRI, sensitivity was 68%, and specificity was 76%. Interobserver agreement was substantial for CBCT (κ = 0.75) and moderate for MRI (κ = 0.56). In addition, CBCT revealed a significant correlation between TMJ disorders and periodontal health (P < 0.05), while MRI showed a weaker association (P < 0.1). We concluded from this study and suggest that CBCT is a more accurate imaging modality for diagnosing TMJ disorders compared to MRI. Moreover, CBCT provides valuable insights into the relationship between TMJ disorders and periodontal health, highlighting the importance of comprehensive dental assessments
