Objectives: The aim of our study was to highlight the advantages of using Cone Beam Computed Tomography in the study of the extent of the alveolar bone loss, compared to the conventional intraoral radiography and to prove the boon of the CBCT scans for establishing the correct periodontal diagnosis. Material and methods: A total of 16 patients with age between 35-55 years old, and a minimum of 8 teeth per dental arcade, presenting peridontal clinical symptomatology were selected. We used a custom periodontal chart that included the measuring of the gingival recession and the pocket depth in 6 points for 16 teeth, 8 maxillary teeth and 8 mandibulary teeth in all cases. For the radiographic evaluation we used CBCT imaging and intraoral radiography. Results: CBCT scans offers the possibilities of measuring with accuracy the alveolar bone loss on mesial, distal vestibular and oral sides. It provides images with the exact position of the bone and also the expediency to assess the correct diagnosis. Retroalveolar radiography offers just a hint of the possible position of the alveaolar bone in all cases the anatomical details were offered by CBCT. Conclusions: A correct periodontal diagnosis using conventional radiography is not possible because of the superimposition of the anatomical structures. The importance of CBCT imaging is no longer disputed, at the present time it is the best radiographic investigation available.

ABSTRACTObjectives:To determine upper incisor root resorption, volume loss, and the relationship between root volume loss and tooth movement after 1 year of orthodontic treatment in patients with marginal bone loss.Materials and Methods:A total of 30 women (46.3 ± 5.4 years old) with moderate upper incisor bone loss who required intrusion during orthodontic treatment were recruited. Pre- and post-treatment cone beam computed tomography images were reconstructed. Upper incisors at pre- and post-treatment were superimposed; labio- and palato-apical, middle, and coronal third root volumes were assessed. Tooth movement and alveolar bone height were measured from lateral cephalometric radiographs and cone beam computed tomography. Changes in root volume/alveolar bone height were compared using paired-sample t-tests, percentage root volume loss for each tooth/segment was evaluated by one-way analysis of variance, and the relationship between percentage root loss and degree of tooth movement was assessed by linear regression.Results:Mean root volume significantly decreased on the labio- and palato-apical aspects of 12 and labio-apical aspects of 21 and 22 (P ≤ .024). Palato-apical segment volume loss was greater on lateral than central incisors (P ≤ .016). Two-dimensional root length and cementoenamel junction-bone crest distance did not change between T0 and T1, with no significant relationship between tooth movement amount and percentage root volume loss.Conclusions:Delivery of 40 g intrusive force to the four upper incisors using a T-loop and the leveling phase lead to more apical root volume loss on lateral than central incisors. There was no relationship between extent of tooth movement and upper incisor root volume loss.

Intrusive luxation is a kind of traumatic injury characterized by an axial displacement of the tooth toward the alveolar bone. Its main causes are bicycle accidents, sports/recreational activities, and falls or collisions. Treatment strategies include waiting for the tooth to return to its position, immediate surgical repositioning and repositioning through dental traction by orthodontic devices. The correct diagnosis must be based on clinical and radiographic exams and it is crucial for decision-making in the treatment of injured patients. Currently, the cone beam computed tomography (CBCT) has been widely used in orthodontics, restorative dentistry and implantology as well as in the diagnosis of complex dental trauma. This article reports a case of severe dental intrusion, in which the cone beam computed tomography (CBCT) was performed because of doubts generated after clinical examination and panoramic radiograph analyze. This case report confirmed that the CBCT is an important exam to correct diagnostic.

Coronal View

The normal alveolar bone crest located at a distance of 1 to 2 mm from CEJ towards the apical. If there is a bone loss, the alveolar bone crest located at 2 mm more to the apical from CEJ. The alveolar bone loss is one characteristic of aggressive periodontitis and the onset of the disease at the age of puberty. The purpose of this research was to know and to assess the height of alveolar bone crest using Cone Beam Computed Tomography (CBCT) in patients with aggressive periodontitis. The type of this research was descriptive. A total of 317 sample CBCT imagery from 6 aggressive periodontitis patients. The result of this research showed that average height of alveolar bone crest second premolar distal, the first molar mesial, first molar distal and second molar mesial on the first region were 3 mm, 4.2 mm, 6.1 mm, and 4.8 mm respectively. On the second region were 3.2 mm, 3.6 mm, 3.6 mm, and 3.4 mm respectively, and in the third region were 2.4 mm, 2.8 mm, 2.5 mm dan 1.4 mm consecutively. While in the fourth region were 2.9 mm, 3 mm, 2.8 mm, and 2.3 mm respectively. The average height of alveolar bone crest of aggressive periodontitis was 3.8 mm. Slicing CBCT imagery on coronal view for the anterior region and sagittal view for the posterior region, showed the characteristic of height alveolar bone crest was arch-shaped which showed the different height of alveolar bone crest of the second premolar distal until second molar mesial.

Root Position

Abstract Background Radiographs are integral in evaluating implant space and inter-root distance. The purpose of this report is to introduce a method for evaluating the 3D root position with minimal radiation using a 3D tooth model composed of an intraoral-scanned crown and a cone-beam computed tomography (CBCT)-scanned root. Materials and methods Intraoral scan and CBCT scan of the patient were obtained before treatment. In the CBCT image, tooth segmentation was performed by isolating individual teeth from the maxillary and mandibular alveolar bone using software program. The 3D tooth model was fabricated by combining segmented individual teeth with the intraoral scan. Results A post-treatment intraoral scan was integrated into the tooth model, and the resulting position of the root could be predicted without additional radiographs. It is possible to monitor the root position after a pretreatment CBCT scan using a 3D tooth model without additional radiographs. Conclusion The application of the 3D tooth model benefits the patient by reducing repeated radiation exposure while providing the clinician with a precise treatment evaluation to monitor tooth movement.

Abstract Purpose The aims of this retrospective cross-sectional study were to measure and compare labial and palatal alveolar bone heights of maxillary central incisors in unilateral cleft lip and palate patients, following STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines. Patients and methods The study group consisted of 21 patients with a mean age of 16 years. High-resolution cone-beam computed tomography was performed at least one year after secondary alveolar bone grafting. The experimental side was the cleft side and the contralateral side without congenital cleft was the control. Measurements were performed on incisors’ midsagittal cross-sections. The Wilcoxon signed-rank test was used for intergroup comparisons. Results The labial and palatal distances between alveolar bone crests and cementoenamel junctions were significantly greater on the cleft side than on the noncleft side. Mean differences were 0.75 and 1.41 mm, respectively. The prevalence of dehiscences at the cleft side maxillary central incisors was 52% on the labial surface and 43% on the palatal surface. In the controls, it was 19% and 14%, respectively. Conclusion The cleft-adjacent maxillary central incisors had more apically displaced alveolar bone crests on the labial and palatal sides of the roots than the controls. Higher prevalence of dehiscences was found on the cleft side. Bone margin differences predispose to gingival height differences of the central incisors. These differences could increase the demands of patients to obtain more esthetic treatment results with orthodontic extrusion and periodontal intervention on the cleft side.
