Root resorption is a pathological process involving loss of hard dental tissues. It may occur as a consequence of dental trauma, orthodontic treatment, and bleaching, and occasionally it accompanies periodontal disease. Although the mechanism of resorption process is examined in detail, its etiology is not fully understood. Wide open apical foramen is more difficult to manage and the root canal may often overfill. In this report we present two cases of root resorption and describe means for its clinical management. We conclude that useful measure of a success or failure in managing root resorption is the persistence of the resorption process. It is a clear sign of an active ongoing inflammatory process and shows the clinical need for retreatment.

Summary The laser coagulation at the apical part of the root canal after vital extirpation is a proper method of preventing complications such as pain, bleeding, remaining vital pulp. The aim of the present survey is to register the thermal changes that occur on the tooth surfaces during laser treatment of the root canal after vital extirpation. An in vitro study of 30 extracted teeth has been conducted. The teeth have been prepared with ProTaper nickel-titanium machine tools and wiped dry. During the course of laser treatment of root canals with a diode laser DenLase temperatures, changes of the surface of the hard dental tissues have been recorded with infrared camera FLIR T330. The captured thermal images have been processed with software product Flir Reporter Pro 9. In conclusion, temperature changes in hard dental tissues at diode laser treatment of the root canal are biocompatible.

Tissue Changes

Tooth movement induced by orthodontic treatment can cause sequential reactions involving the periodontal tissue and alveolar bone, resulting in the release of numerous substances from the dental tissues and surrounding structures. To better understand the biological processes involved in orthodontic treatment, improve treatment, and reduce adverse side effects, several of these substances have been proposed as biomarkers. Potential biological markers can be collected from different tissue samples, and suitable sampling is important to accurately reflect biological processes. This paper covers the tissue changes that are involved during orthodontic tooth movement such as at compression region (involving osteoblasts), tension region (involving osteoclasts), dental root, and pulp tissues. Besides, the involvement of stem cells and their development towards osteoblasts and osteoclasts during orthodontic treatment have also been explained. Several possible biomarkers representing these biological changes during specific phenomenon, that is, bone remodelling (formation and resorption), inflammation, and root resorption have also been proposed. The knowledge of these biomarkers could be used in accelerating orthodontic treatment.

Treatment Application

There are no relevant contraindications to orthodontic treatment of previously endodontically treated teeth, considering the quality of the obturated teeth, the health of the periodontal membrane, along with careful application of orthodontic force. Although, there is usually some degree of reversible or transient pulpal inflammation  even  in  healthy  teeth  during  orthodontic  treatment,  application  of  light  and  intermittent orthodontic force will reduce the risks provided sufficient time is given to allow proper repair of the dental tissue.  However,  there  may  be  a  few  hazards  associated  with  the  treatment  of  endodontically  involved teeth, some of which mainly include root resorption and ankylosis. This article will show some cases of teeth which had undergone  root canal treatment prior to orthodontic management and further observed whether orthodontic tooth movement had caused any resorption in the root filled teeth.  Root canal treated teeth can be moved orthodontically to the same extent as vital teeth, providing, a controlled force applica- tion to avoid risk of inflammatory root resorption.

ABSTRACT Introduction: Invasive cervical resorption (ICR) is a relatively rare type of ERR (External Root Resorption), in which a localized resorption begins in the cervical area of the tooth, below the epithelial junction and above the ridge crest. Objective: Describe the clinical case of an 11-year-old boy with no dental trauma history, presenting moderate crowding and ectopic eruption of the maxillary right central incisor. He had been undergoing orthodontic treatment elsewhere, and his family was dissatisfied with the results. Description: A new treatment was indicated, which included rapid maxillary expansion followed by extraction of four premolars. During routine panoramic evaluation, a radiolucid image was detected and a periapical radiograph was requested. At this point, an ICR of the maxillary right central incisor was found. The treatment was cautiously finalized and despite the use of light forces, central incisor was severally compromised by ICR and was therefore extracted. Conclusion: This clinical example discusses the importance of routine radiographs for the early diagnoses of ICR.

Relevance. Skeletal malocclusion stands at the head of all oral diseases and is encountered in 32-35% of children and adolescents in Russia [7;12;15]. The number of malocclusions has increase due to various reasons, one of which is early extraction of deciduous carious teeth resulting in impaired vertical dimension and occlusion of teeth [1;14]. Diagnosis with due regard to caries resistance degree and planning of respective operative and orthodontic treatment are indispensable in children with skeletal malocclusion. Purpose – to increase effectiveness of functional treatment of malocclusion in children with various degree of caries resistance.Materials and methods. There were examined 108 patients aged between 6 and 16 with Class I malocclusion according to Angle, abnormal arch-to-arch relationship and tooth position and various degree of caries resistance. 4 groups were formed: high, sufficient mean, decreased mean and low caries resistance of dental enamel. Intensity of carious process was detected in all patients before and after orthodontic treatment. The effectiveness of reminerlization administered by removable orthodontic appliances was evaluated by electrometrical testing of hard dental tissue. Surface EMG was used to assess normalization of tone of maxillofacial muscles in children by average amplitude of biopotentials of superficial masseter and temporalis muscles.Results. Сhanges in caries intensity in children after treatment with removable orthodontic aligners indicate the necessity for remineralization of hard dental tissues during orthodontic treatment and it is confirmed by decrease of electroconductivity of enamel in children with sufficient mean, decreased mean and low degree of dental enamel caries resistance. Increase of biopotential mean amplitude during «total mastication» for masseter and temporal muscles confirms effectiveness of preformed elastic positioner along with myodynamic exercises.Conclusions. The conducted study proves the necessity of comprehensive approach with procedures  increasing the degree of caries resistance of hard dental tissues during orthodontic treatment of skeletal malocclusion in children.

Even though orthodontic treatment is indispensable for nearly 16-20% of the whole world population with functional efficiency, structural balance and aesthetic harmony as its main advantages and rationale, the treatment particularly with a range of removable, fixed, functional and extraoralorthopaedic appliances can cause various deleterious hard tissue and soft tissue injuries in particular, intraorally. These intraoral and extra oral hard and soft tissue injuries can be iatrogenic, self-induced, caused by bad patient compliance or just by accidents intervened by the patient while wearing the appliance. These traumas/injuries are not uncommon since an orthodontic treatment are mainly done with stainless steel [metal] and the treatment usually continues for a long period of time ranging from 6- 36 months in themajority of the cases. The high pervasiveness of individuals with dental trauma preceding to orthodontic treatment justify the safety measures that should be followed before and during treatment while bearing in mind all the possible effects of orthodontic movement on traumatized teeth. Among the major traumatic dental injuries, avulsion with subsequent tooth reimplantation entails a higher than average risk of complications, such as pulp necrosis, root resorption,and ankyloses. Therefore, it gives orthodontists numerous reasons for apprehension during orthodontic treatment.

AbstractExternal invasive root resorption may occur as a consequence of trauma, orthodontic treatment, intracoronal bleaching and surgical procedures and may lead to the progressive and destructive loss of tooth structure. Depending on the extent of the resorptive process, different treatment regimens have been proposed. A 20-year-old female patient presented with tooth showing signs and symptoms of pain in 21 with extensive invasive resorption in middle third of root canal. After root canal treatment, The resorption area was chemomechanically debrided using ultrasonic tips and irrigant solution. MTA was used to fill the resorptive defect and the coronal access was temporarily sealed. Radiographs at 3 and 12 months showed adequate repair of the resorption and endodontic success. Clinically, the tooth was asymptomatic and found to be functioning well.

Background: Dental caries is an infectious and multifactorial pathological process that destroys hard dental tissues, and Streptococcus mutans is found as the main microorganism associated with this disease.a multifactorial infectious disease, and, in its etiology, diverse microorganisms are involved, among which Porphyromonas gingivalis is of vital importance due to its virulence factors and role in the development of periodontal pathology. Purpose and Method: This integrative review article built on the basis of previously published research experiences of the authors of this document and contrasted with other studies worldwide, aimed to describe the microbiological and molecular characteristics of S. mutans and P. gingivalis, microorganisms, respectively, of great importance in dental caries and periodontal disease. Important studies were found with the use of the following keywords or medical subject headings (MeSH) in Pubmed, Scopus and Google Scholar: “S. mutans” and “P. gingivalis” and "phenotypic identification" and "genotypic characterization”. Results: From S. mutans, different biotypes were identified according to the methodology used, wide antimicrobial susceptibility and genotypic variability by AP-PCR that depends on the nesting of the primers on the DNA. Of P. gingivalis, high susceptibility to antimicrobials and broad genotypic discrimination were found by the AFLP technique. Conclusion: the deep phenotypic and genotypic knowledge of S. mutans and P. gingivalis, bacteria of great importance in dental caries and periodontal disease, together with the classical epidemiological study could be very important in the application of better prevention and control strategies that impact the oral public health in these two diseases.
