Introduction: Root resorptions are, with white spots, some of the inconveniences caused by orthodontic treatments. Although they are rare, they should not be ignored despite the many benefits gained by orthodontic treatment. Contrary to white spots, which are controllable by good dental hygiene, root resorptions can occur despite patient cooperation. Orthodontists should be aware of this phenomenon and make regular radiologic controls a priority for detection “before, during and after” treatment. Material and Method: After literary references, the presentation of the case report will illustrate the role of the orthodontist in the preservation and care of teeth damaged by impacted cuspids. Discussion: The discussion will focus on the prevention and the interception of those phenomena, the etiologic research on these cases, on medical supervision and prognostic for damaged teeth. Conclusion: Before the conclusion, we will evoke the contribution of the cone-beam in the diagnosis of root resorption.

The aim of this paper is to provide a review on the role of inflammation in orthodontically induced inflammatory root resorption (OIIRR) and accelerating orthodontic tooth movement (AOTM) in orthodontic treatment. Orthodontic tooth movement (OTM) is stimulated by remodeling of the periodontal ligament (PDL) and alveolar bone. These remodeling activities and tooth displacement are involved in the occurrence of an inflammatory process in the periodontium, in response to orthodontic forces. Inflammatory mediators such as prostaglandins (PGs), interleukins (Ils; IL-1, -6, -17), the tumor necrosis factor (TNF)-α superfamily, and receptor activator of nuclear factor (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) are increased in the PDL during OTM. OIIRR is one of the accidental symptoms, and inflammatory mediators have been detected in resorbed roots, PDL, and alveolar bone exposed to heavy orthodontic force. Therefore, these inflammatory mediators are involved with the occurrence of OIIRR during orthodontic tooth movement. On the contrary, regional accelerating phenomenon (RAP) occurs after fractures and surgery such as osteotomies or bone grafting, and bone healing is accelerated by increasing osteoclasts and osteoblasts. Recently, tooth movement after surgical procedures such as corticotomy, corticision, piezocision, and micro-osteoperforation might be accelerated by RAP, which increases the bone metabolism. Therefore, inflammation may be involved in accelerated OTM (AOTM). The knowledge of inflammation during orthodontic treatment could be used in preventing OIIRR and AOTM.

Root resorption in moved teeth is a common undesirable side effect of orthodontic treatment. This pathology usually affects permanent teeth. Although any part of the root may be involved, the apical or cervical area is usually affected. The formation and development of these changes are a long-term process and depend on various factors. The etiology of resorptive changes associated with orthodontic treatment has been widely discussed by many authors, who proposed numerous classifications. Particularly noteworthy are the works on techniques for the treatment of malocclusion and their potential adverse effects. Modern diagnostic methods allow for an early detection of this pathology and the implementation of appropriate therapeutic measures. These techniques include periapical radiography (paralleling technique) combined with cone-beam computed tomography. Dentists not only notice the need to achieve a beautiful smile, but they also take into account possible root shortening. This process is not fully understood, but realizing its existence is important for planning and implementing both orthodontic and general dental treatment.

ABSTRACT This study discusses the role of orthodontic treatment as an adjunct to the control and treatment of periodontal disease conditions, and describes a clinical case of severe anterior mandibular crowding and periodontal disease followed up for nine years and three months after orthodontic treatment completion. Malocclusion impaired proper dental hygiene, which led to bone loss and development of a periodontal abscess between mandibular canines and lateral incisors. After scaling and root planing, orthodontic treatment was initiated with extraction of the four second premolars, to correct the deficiency detected in cephalometric and model analysis. Treatment objectives were met, and facial and dental esthetics was satisfactory. Adequate periodontal management, hygiene control and tooth movement ensured ideal occlusion and facilitated the control of biofilm.

Aim. The aim of the work was to present the latest directions in the research on gene polymorphisms in the global population and to discuss their potential role in the pathogenesis of root resorption during orthodontic treatment. Material and methods. A review of the literature in Polish and English from the years 1990–2015 was conducted using PubMed/MEDLINE databases and the results of studies kept in the database of the National Centre for Biotechnology Information were used. Key words used: genetics of root resorption, genetic polymorphism, interleukin-1B. Results. 19 articles were analysed. Special attention was placed on the latest studies on the human genome, especially focused on gene polymorphisms in the global population. Summary. Pathogenesis of root resorption during orthodontic treatment is complex. Its background is undoubtedly genetic. Gene polymorphism is important. The role of polymorphism of the interleukin-1B gene and other genes in the interleukin-1 cluster draws special attention. Identification of genetic factors that play an important role in the aetiology of root resorption may in the future help to identify patients susceptible to such complications even before the beginning of orthodontic treatment. Potential possibilities of DNA testing in clinical practice are enormous. The role of individual gene polymorphisms in the pathogenesis of root resorption has not been yet explained in detail and further multicentre studies are necessary. At this stage of studies no reliable markers have been detected in order to predict which patients would develop this complication. (Makowska- Kaczmarska M, Okoń A, Olszewska E.

Summary Introduction. Although severe root resorption is rare, it is a side effect of orthodontic treatment which affects tooth prognosis. Patients with severe dentofacial deformity, for whom orthodontic treatment and orthognathic surgery was done at the age of 18 and later, had long duration orthodontic treatment and orthognathic surgery, and are at a high risk of root resorption. The impact of orthognathic surgery on root resorption has not been sufficiently studied, and therefore is an interesting topic to research. Aim of the Study. To identify the risk factors for apical root resorption of maxillary incisors and canines as a result of orthodontic and surgical treatment of Class III malocclusion involving LeFort I osteotomy. Material and methods. The root lengths of upper incisors and canines were measured on cone beam computer tomography (CBCT) scans obtained from a database of orthognathic surgery patients. As a criteria for root resorption was chosen the difference in root lengths between different time points. The measurements were performed using the scans taken before orthodontic treatment (T1), before surgery (T2), and after post surgery orthodontic treatment (T3), of 28 subjects, aged 20.5 ± 3.81 years, with the mean presurgery treatment time of 19.9 ± 8.8 months, and post-surgery time of 7.1 ± 3.1 months. Changes in root lengths during different time spans were correlated with treatment duration, the initial crown/root ratio, and the severity of dentofacial deformity (Wits appraisal, ANB angle, and overjet). Results. During T1 - T2 the roots of the lateral incisors shortened by a maximum of 0.78 ± 0.83 mm (p < 0.001), at a rate of 0.04 mm per month. During T2 - T3 the lengths of the central incisor roots decreased most by 0.49 ± 0.52 (p < 0.001) at a rate of 0.07 mm per month. The resorption speed for canines increased from 0.03 mm to 0.1 mm per month before and after surgery. There were statistically significant correlations between the crown-root ratio and the incisor root length (r = 0.319 for lateral and r = 303 for central, both p<0,05) and for canines (r = 482, p<0.01). The associations between the shortened root length, in different time spans for different teeth, and the severity of malocclusion were inconsistent. Conclusions. Overall, the shortened root length during combined orthodontic and surgical treatment might not be clinically significant. After surgery, the rate of root resorption (mm per month) increased, especially for canines. The teeth with initially shorter roots showed more resorption during treatment.

Maxillary Incisors

Background: Maxillary anterior teeth play a crucial role in aesthetics, phonetics, and mastication. For successful orthodontic treatment evaluating the morphology of the alveolar bone and incisive canal would help in avoiding root resorption, dehiscence, and fenestration. This study is aimed to research the configurational relationships among maxillary incisors, alveolar bone, and incisive canal through Cone Beam Computerated Tomography (CBCT). Methods: CBCT images of 35 orthodontic patients were evaluated for length of the canal (L); angles between the palatal plane and the maxillary alveolar border (01),the incisive canal (02), and maxillary incisor (03); distance from the right maxillary incisor to the incisive canal (D). All the measurements were performed on sagittal plane with the exception of (D) which was made on axial plane. Statistical analysis was performed on the above parameters using two sample test and Pearson’s correlation analysis. Results: There was no statistically significant difference between males and females for all the variables although there were large interindividual variation. There was a positive moderate correlation between 01 and 02 (0.480), 01 and 03 (0.487), 02 and 03 (0.345). The mean value for L and D were 10.38mm and 4.14mm respectively. Conclusion: There exists a large interindividual variability for incisive canal, proximity of incisors with that of incisive canal which could not be precisely predicted by the conventional cephalograms. The results of the study could be helpful clinically in planning orthodontic treatment for significant intrusion and retraction of maxillary incisors

Objective: To explore the cure rate of bracketless invisible headgear orthodontic for opening deep occlusion of anterior teeth. Methods: 10 cases with deep occlusion of anterior teeth were selected. All of the patients were admitted to our hospital from January 2017 to January 2020. All selected patients received bracketless invisible headgear orthodontic treatment. We took CBCT (cone beam CT) before and after orthodontics) lateral cranial radiographs and curved tomographic radiographs to analyze the effect of orthodontic treatment in 10 patients. Results: The changes of 10 patients before and after the orthodontic treatment were not significant in U1-SN, U6-SN, MP-FH (P>0.05); the U1-PP of the patients all decreased by 3~5mm. Compared with the effect before orthodontic treatment, the difference is significance(P<0.05); The tooth loosening didn’t occur obviously in 10 patients. And 2 patients (20.00%) had mild root resorption in the anterior teeth. Conclusion: The effect of invisible headgear orthodontic treatment without brackets is significant in orthodontic treatment of patients with deep occlusion of anterior teeth. The pressure of the upper anterior teeth can reach as low as 3~5mm. The cure rate of deep occlusion of open anterior teeth is high. The orthodontic method is comfortable, with beautiful appearance, which is easier to be accepted by patients.
