Abstract

Background: This study designed to shade light on the important role of CBCT in accurate localization of theimpacted maxillary canines.Materials and method: Fifty two unilateral and bilateral impacted maxillary canines from 30 patients (24 females and6 males) were evaluated by a volumetric 3D images obtained from cone beam CT. All samples attended to thespecialist health center of dentistry in Al-Sadder City referred to CBCT by oral surgeons or orthodontists to detect theexact position of impacted upper canine in cases when there was no bulging buccally or palatally which aids todetect the exact position.Results: Mesio-palatal angulations had the highest rate (63.5%) followed by mesio-labial (19.2%), vertical (labial)(9.6%), disto-palatal (5.8%) and disto-labial (1.9%). The relation between impacted canine and the adjacent teethregarding to the attachment was significant only with lateral incisor. No cases of root resorption of the adjacentteeth were recorded. Bilateral impacted teeth were found in 22 patients which is highly significant (especially infemales), while unilateral impaction was found only in 8 patients especially in females. Impacted canine was moreprominent in female whether unilateral or bilateral.Conclusions: CBCT imaging of impacted canines can show the following: presence or absence of the canine,angulations of the long axis of the tooth, relative labial and palatal positions and proximity to adjacent teeth. In short,CBCT imaging is clearly advantageous in imaging and management of impacted canines

Abstract

Background: Preoperative radiographical assessment of the maxillofacial lesions is of a great importance in guiding the surgeon during surgical procedure in reducing post-operative complications. This study highlighted the application of CBCT scan in the assessment of maxillofacial cystic and cystic like lesions as a part of advanced radiology Materials and methods: A total of 20 patients (15 males and 5 females) participated in this prospective study. CBCT scan (Kodak 9500 CBCT) with (DICOM) software utilized to perform scanning to all patients in order to assess lesion extension, morphological features and it’s relation to the adjacent vital structures.Results: In this study, the total cystic and cystic like lesions involving the maxilla and mandible were (20) lesions. Statistical analysis of the collected data showed no significant differences between the radiographical records and surgical findings regarding diagnostic accuracy of the lesions.Conclusion: The validity of the CBCT in the assessment of maxillofacial cystic and cystic like lesions was similar to the surgical findings regarding lesion extension, expansion, perforation of buccal/or lingual plates, and relation to the adjacent vital structures.

Abstract

background: osteoporosis is a metabolic bone disease that affects women more than men, it is characterized by generalizes reduction of bone mineral density (BMD) leaving a fragile weak bone that is liable to fracture, gonial angle index (GAI) is one of the radio-morphometric indices, it has been controversial whether it is related to bone mineral density or ageing or none of them. The aim of study is to evaluate the role of cone beam computed tomography (CBCT) as a screening tool for diagnosis of osteoporosis and age effect in females using gonial angle index.Material and method: 60 females were divided into 3 groups according to age and (BMD) status into: Group1 (non-osteoporosis 20-30 years), Group2 (non-osteoporosis 50years and above), and Group3 (osteoporosis 50years and above), each patient had a CBCT scan, and gonial angle index was measured compared among groups.Results: Gonial angle index showed a significant difference between Group1 and Group2 at p < 0.05, while it showed no significant difference between Group2 and Group3 at p > 0.05.Conclusion: Gonial angle index is significantly affected by age factor while it was not affected by osteoporosis, so it cannot be used as a parameter that can predict bone mineral density status patients

Abstract

Background: Periodontitis is an inflammatory disease that affects the supporting tissues of the teeth; Smoking is animportant risk factor for periodontitis induces alveolar bone loss and cause an imbalance between bone resorptionand bone deposition. The purpose of this study is to detect and compare the presence of incipient periodontitisamong young smokers and non-smokers by measuring the distance between cement-enamel junction and alveolarcrest (CEJ-Ac) using Cone Beam Computed Tomography (CBCT).Material and methods: The total sample composed of fifty two participants, thirty one smokers and twenty one nonsmokers(age range 14-22 years). Periodontal parameters: plaque index (PLI), gingival index (GI) were recorded forall teeth except the third molar while the radiographic analysis using CBCT was recorded on the Ramfjord teeth, theunit of measurement was from cement-enamel junction to alveolar crest distance (CEJ-Ac distance) per site inmillimeters.Results: The results obtained were a non significant difference for PLI, a significant difference of mean of GI betweenyoung smokers and non smokers. There was a highly significant difference in the general mean of CEJ-Ac distancebetween both groups. There was a significant difference between maxillary and mandibular teeth, a non significantdifference between right and left sides among young smokers and non smokers.Conclusion: The CBCT device plays an important role in detection the incipient form of periodontitis among youngsmokers and non-smokers, so we concluded that there is a highly significant difference in the general mean CEJ-Acdistance between young smokers and non smokers with increase distance in the maxillary teeth than that in themandibular teeth

Abstract

Backgrounds: Maxillary canine impaction is complicated and time consuming to treat, for being highly diverse in inclination and location; it may be a companied by root resorption of the neighboring teeth. CBCT has been used for its' diagnostic reliability in localization of impacted canine and revealing its' serious local complications.Objectives: Localization of maxillary impacted canine using cone beam computed tomography for assessment of angulation, distance from occlusal plane, alveolar width and proximity to adjacent teeth.Subjects and Methods: The study sample was 33 subjects 16 females and 17 males attended to Al-Wasitti general hospital in Baghdad city-Oral and maxillofacial radiology department for CBCT scan investigationfrom November/2015 to April/2016. By using theCS 9000 device, 3D images and coronal, axial and sagittal views obtained to perform the selected measurements.Results: Contact of impacted canine to the nearby teeth had a strong effect on their root resorption. Vertical or horizontal angulation measurement in axial view, was not possible for a number of cases.Comparison of the angulation measurement validity between axial and coronal views, had showed an obvious statistical difference in coronal view for vertical angulation, and in the axial view for horizontal angulation calculation. Correlation of the canine localizations found in the study with the measurements, showed a significant statistical difference with age and vertical angulation (coronal view). Age or gender correlation with the measurements wasnon significant statistically, except for age with vertical angulation (coronal view).Conclusion: utilization of CBCT provides a worthy data about the impacted maxillary canine localization, for more explanation and treatment of these cases surgically and by orthodontics.
