Comprehensive and appropriate occlusion reconstruction therapy is necessary for orthodontic treatment of adult patients with malocclusion with periodontal disease associated with occlusal trauma. We report the case of a patient with extensive moderate chronic periodontitis associated with occlusal trauma. The patient was diagnosed with extensive moderate chronic periodontitis associated with occlusal trauma and underwent thorough treatment for periodontal disease, oral management, and 20 months of orthodontic therapy. Moreover, reconstructed occlusion was performed to evaluate occlusal trauma for visualization using Brux Checker (BC) analysis before and after active orthodontic treatment. The patient acquired stable anterior guidance and a functional occlusal relationship. BC findings revealed weakening of the functional contact between the lateral occlusal force of the dentition and the front teeth and alveolar bone regeneration. The laminar dura became clearer, and the periodontal tissue improved. Our results suggest that assessment of occlusion function using BC analysis and periodontal examination was effective in enabling occlusal treatment goal clarification through orthodontic treatment in case of periodontal disease associated with occlusal trauma.

Objective: In recent years, advances in technique as well as a growing public interest in developing and maintaining a healthy and attractive smile, has resulted in a greater understanding of the interrelationships between periodontics and orthodontics. The primary objective of periodontal therapy is to restore and maintain the health and integrity of the attachment apparatus of teeth. In adults, the loss of teeth or periodontal support can result in pathological teeth migration involving either a single tooth or a group of teeth. This may result in the development of a diastema, incisal proclination, rotation with collapse of the posterior occlusion.Materials and methods: This case report is of a 32 year old female patient who reported with swollen gums, generalized spacing between the teeth and extruded upper anterior tooth. Periodontal therapy followed by fixed orthodontic therapy was planned.Results: At the end of 2 years a stable healthy periodontium was established that was both functional and esthetic.Conclusion: Adjunctive orthodontic therapy is often necessary for successful restoration of periodontal health. On the other hand, successful orthodontic treatment will depend on the periodontal preparation before and after treatment and the maintenance of periodontal health throughout all phases of mechano-therapy.

ABSTRACT Objective: To evaluate changes in shape and alterations in thickness and vertical marginal bone levels of the alveolar bone around the maxillary and mandibular incisors before and after orthodontic treatment with premolar extraction using geometric morphometric analysis. Materials and Methods: Thirty-six patients with Class I bialveolar protrusion who underwent orthodontic treatment with premolar extraction were included. Cone-beam computed tomographic scans were obtained from the patients before and after treatment. Five fixed landmarks and 70 semilandmarks were used to represent the morphology of the alveolar bone around the maxillary and mandibular incisors. The coordinates of the landmarks of the alveolar bones were generated by Procrustes fit. The labial and lingual alveolar bone thicknesses around the maxillary and mandibular incisors and vertical marginal bone level were assessed quantitatively. Results: There was a significant difference in shape change of the alveolar bone before and after treatment. The deformation grid of the thin plate spline showed that the thickness and vertical marginal bone decreased on the lingual side after treatment. Shape changes were greater for the lingual alveolar bone on the mandibular incisor than for the maxillary incisors. Conclusions: Orthodontic treatment with premolar extraction might cause loss of alveolar bone around the maxillary and mandibular incisors. Careful consideration is needed to avoid iatrogenic degeneration of periodontal support around the incisors, particularly in the lingual area.

Objective: To test the hypothesis that it is possible to perform rapid maxillary expansion (RME) after alveolar bone grafting in patients with clefts of the lip and palate (CLP) without compromising the final result of the bone graft. Design: Occlusal and periapical radiographs of the grafted area of 17 unilateral and 11 bilateral patients with CLP (n  =  28) were obtained before and after RME. Setting and sample population: Hospital for Rehabilitation of Craniofacial Anomalies (HRAC), University of São Paulo. Twenty-eighty patients with CLP who had undergone RME. Interventions: RME was performed in patients with CLP who had already undergone RME before secondary bone grafting but with relapse of the maxillary dental arch constriction, as well as in patients with CLP who had never undergone expansion before bone grafting. Outcome measure: Qualitative evaluation in occlusal and periapical radiographs after alveolar bone grafting. Results: Findings showed opening of the midpalatal suture in 42.8% of patients in this study. Regardless of the success rate of RME, the alveolar bone grafting was not affected when the procedures were inverted. Conclusion: The hypothesis was accepted. RME can be performed after secondary alveolar bone grafting without affecting it.

The aim of the present study was to assess the cumulative radiographic alveolar bone loss (CRABL) and yearly radiographic periodontal attachment loss (YRABL) of periodontal disease groups over 5 years or more. A total of 53 subjects, who had taken two sets of full-mouth standardized paralleling radiographs with separated periods of 5 years or more in Kaohsiung Medical University Hospital during 1981-2001, were collected for the past 20 years. The radiographic alveolar bone levels at mesial and distal aspects of teeth were assessed by measuring the distance between cemento-enamel junction and alveolar bone crest using an electronic digimatic caliper (EDC) under a 3.5X magnified radiographs. The results revealed that 1) patients with a periodic recall (3-4 times/yr.) showed a significantly lower loss rate than patients without periodic recalls; 2) mean CRPAL was highest in the generalized aggressive periodontitis (GAgP) group (5.52±3.27mm), then the chronic periodontitis (CP) group (4.82±3.47mm), and the localized aggressive periodontitis (LAgP) group (4.47±3.47mm) followed, and lowest in the periodontal healthy (PH) group (1.05±0.59mm); 3) mean YRPAL was the highest in the LAgP group (0.26±0.25mm/yr.), then the GAgP group (0.20±0.13 mm/yr.), and the CP group (0.12±0.09 mm/yr.) followed, and lowest in the periodontal healthy group (0.07±0.06 mm/yr.). It was concluded that: 1) sites with more advanced alveolar bone loss are more likely to undergo further breakdown; 2) patients with a periodic recall showed a significantly lower alveolar bone loss rate and bone gain, irrespective disease groups; 3) mean CPBLs was highest in the GAgP group; mean YRABLs was highest in the LAgP.

Background/Aim. Healthy periodontium comprises the dento-gingival junction. Periodontal disease starts to appear when the integrity of the junctional epithelium is disturbed. Assessment of the supracrestal tissue attachment (SCTA) is essential because there is a frequent need for restoration or prosthesis after periodontal surgical and non-surgical therapy. The aim of the present study was to evaluate the SCTA variations in a patients with chronic periodontitis before and after treatment. Methods. Thirty systemically healthy patients with periodontitis were enrolled in the study. Fifteen patients were subjected to scaling and root planing and 15 to open flap debridement. Radiographic and clinical findings of the SCTA were assessed before and after treatment at 3-month and 6-month intervals. Results. Comparison between clinical and radiographic findings of the SCTA showed a significant difference in patients with periodontitis (p < 0.05). This difference was not significant after treatment of patients with shallow pockets with scaling and root planing (p > 0.05), but showed a significant difference in patients with moderate pockets treated by open flap debridement (p < 0.05). Conclusion. Progression in periodontal disease causes a reduction in the SCTA dimension, which regains its original dimensions after periodontal therapy. It takes around 3 months for the shallow pockets to regain the supracrestal tissue attachment to the original dimension when treated by scaling and root planing, whereas moderate pockets regain it after 6 months when treated with open flap debridement.

Stimulating Factor

Background: Oral pathogens may exert the ability to trigger differently the activation of local macrophage immune responses, for instance Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans induce predominantly pro-inflammatory (M1-like phenotypes) responses, while oral commensal microbiota primarily elicits macrophage functions consistent with the anti-inflammatory (M2-like phenotypes). Methods: In healthy individuals vs. periodontal disease patients’ blood samples, the differentiation process from monocyte to M1 and M2 was conducted using two typical growth factors, the granulocyte/macrophage colony stimulating factor (GM-CSF) and the macrophage colony stimulating factor (M-CSF). Results: In contrast with the current literature our outcomes showed a noticeable increase of macrophage polarization from healthy individuals vs. periodontal patients. The biological and clinical significance of these data was discussed. Conclusions: Our translational findings showed a significant variance between control versus periodontal disease groups in M1 and M2 marker expression within the second group significantly lower skews differentiation of M2-like macrophages towards an M1-like phenotype. Macrophage polarization in periodontal tissue may be responsible for the development and progression of inflammation-induced periodontal tissue damage, including alveolar bone loss, and modulating macrophage function may be a potential strategy for periodontal disease management.

Background: There is great controversy regarding the effect of MBT and Damon bracket systems on dental arch dimensions and incisor position. Objectives: We aimed to study the effects of two different brackets (MBT and Damon) on dental arch dimensions and incisors position after orthodontic treatment. Methods: In this retrospective study, the records of 20 patients who underwent orthodontic treatment with MBT or Damon bracket systems were studied. All patients had class I skeletal and dental malocclusion and were treated without extraction. The patients were treated either with Damon or MBT bracket systems (n = 10). Lateral cephalograms were traced using the Dolphin software to determine the position of incisors. In addition, transverse dimensions of dental arches were measured on occlusal photographs. Fishers’ exact test, independent-test, Man-Whitney, paired t-test, and Wilcoxon were used for statistical analysis. P < 0.05 was set as significant. Results: There was no significant difference between the two groups regarding age, sex, and initial values of the variables studied. U1-Apog (mm), upper inter-canine, lower inter-second premolar distance showed a significant difference before and after treatment in the Damon system. However, no significant difference was observed between initial and post-treatment values in the MBT group. L1-Apog (°), IMPA (°), maxillary inter-first and second premolars, inter-canine, and mandibular inter-canine distance was higher in the Damon system after treatment compared to MBT. Changes of the upper and lower transverse dimensions of the dental arches and the incisor positional did not reveal a notable difference in the Damon and MBT systems (P > 0.05). Conclusions: There was no significant difference regarding changes in dental arches and incisor positions between the Damon and MBT systems.

Abstract Nickel and cobalt are major components of alloys used in orthodontics. The objectives of this cross-sectional study was to determine the prevalence of a nickel hypersensitivity reaction before and after orthodontic treatment with conventional stainless steel brackets and wires. The total sample consisted of 82 patients (55 females, and 27 males) from the Orthodontic Department at the Faculty of Dentistry, Süleyman Demirel University. A patch test and a questionnaire were used to evaluate hypersensitivity to these metals. The statistical analysis was carried out using Fisher's exact X2 (2 x 2) test. The prevalence of nickel allergy was found to be higher in females than males (14.55% in females, 0% in males), and the prevalence of cobalt allergy was found to be 9.76% (7.27% in females, 14.81% in males). Orthodontic treatment with conventional stainless steel alloys does not appear to have an allergenic effect on the gingival and oral health of the patient. A family history of an allergy to these metals or the use of metallic objects in contact with the skin do not characterize nickel and cobalt hypersensitivity. This suggests orthodontic therapy with conventional stainless steel appliances does not initiate or aggravate a nickel hypersensitivity reaction. There was no association between the before treatment and after treatment to a nickel and cobalt hypersensitivity reaction. Citation Saglam AMS, Baysal V, Ceylan AM.

Abstract Aim To examine alveolar bone level (ABL) changes before (T1) and after (T2) orthodontic treatment (OT) in subjects with periodontal disease. Methods The study included 50 subjects with periodontal disease. All patients received subgingival debridement following baseline examination. Control group patients received final periodontal treatment before the start of OT. For the test group patients final periodontal treatment was performed simultaneous to OT. OT was performed with a straight-wire appliance. Micro-implants or temporary crowns on implants were used for posterior anchorage when needed. ABL measurements of 3821 tooth surfaces were performed on cone beam computed tomography images. Results No difference was observed between mean ABL at T1 and T2. ABL remained unchanged on 69 per cent of surfaces. A mean of 15.6 (SD 7.4) per cent of surfaces experienced ABL gain, and a mean of 15.1 (SD 7.5) per cent was found with ABL loss. Small significant median ABL difference was observed on mesial and distal surfaces (P < 0.001). A significant difference was found between median ABL changes on mesial/distal in comparison to buccal/lingual surfaces (P < 0.01). Significantly more buccal (17.9 %) and lingual (18.5 %) surfaces experienced ABL loss when compared with mesial (11.3 %) and distal (12.0 %) surfaces (P < 0.001). Significant difference was found in the median ABL change of intruded (0.5 (IQR 0.94) mm) and non-intruded (−0.4 (IQR 1.07) mm) maxillary incisors (P = 0.04). Significant median ABL gain was found on the lingual surface of maxillary incisors, which were retroclined more than 8.6 degree and intruded more than 1.6 mm. Conclusions ABL changes after periodontal–orthodontic treatment in patients with periodontal disease were small. ABL gain was more observed on mesial and distal surfaces and ABL loss on buccal and lingual surfaces. Larger orthodontic movements of maxillary incisors influenced ABL gain.

ABSTRACT Objective:  To evaluate the distance between the cementoenamel junction and the alveolar bone crest before and after orthodontic treatment using cone beam computed tomography (CBCT). Materials and Methods:  The sample comprised 30 patients with Angle Class I malocclusion and mild to moderate crowding. The study database comprised dental CBCT scans obtained before and after orthodontic treatment. The distance between the cementoenamel junction to the bone crest of the buccal (n  =  720) and lingual (n  =  720) surfaces was measured in 24 teeth for each patient using a specific software tool (Xoran version 3.1.62). The Wilcoxon test was used for statistical analysis, and the level of significance was set at P &lt; .05. Results:  The distance between the cementoenamel junction and the bone crest increased in 822 (57%) of the 1440 surfaces after orthodontic treatment. The buccal surface of the lower central incisors had the greatest frequency of increased distance (75%), and the lingual surface of lateral incisors had the lowest (40%). The distance between the cementoenamel junction and the alveolar bone crest was greater than 2 mm (alveolar bone dehiscence) in 162 (11%) of the 1440 surfaces before orthodontic treatment and in 279 (19%) after treatment. Conclusions:  The distance from the cementoenamel junction to the bone crest changed after orthodontic treatment; the distance was greater than 2 mm in 11% of the surfaces before treatment and in 19% after treatment.
