Анкетування як важливий інструмент для виявлення факторів впливу на затримку прорізування зубів

Aim. To identify risk factors for delayed eruption of permanent anterior teeth in children aged 7 to 14 years, based on clinical examination, radiological examination, parental/caregiver questioning. Materials and Methods. The study included Ukrainian children aged 7-14 years who had delayed eruption of permanent teeth. They were divided into two groups. Group I was composed of 56 (40.0%) children aged 7-9 years with early mixed dentition; Group II was made of 84 (60.0%) individuals aged 10-14 years who had the final stage of mixed dentition. After careful history taking and physical examination, a clinical examination was performed to identify abnormal positions of incisors or canines and to determine the condition of the oral cavity and the bite; a radiological examination included CBCT; and the children’s parents /caregivers were surveyed with the use of the questionnaire we had developed. Results. It has been established that the main risk factors for delayed eruption of permanent teeth are arch-length deficiency, recurrent colds, respiratory disorders, delay in chewing food, pathology in the first trimester of pregnancy, premature extraction of primary teeth, use of a pacifier, delayed loss of deciduous teeth, bad habits, allergies, formula and mixed feeding, orthodontic treatment in the parents’ history, ectopic teething, and injuries to the maxillofacial area in children. Conclusions. A comprehensive history taking, an appropriate determination of the stages of dental development and an assessment of the potential risks of delayed teething are of paramount importance in the diagnosis of pathology, as they allow for the prediction of future orthodontic complications. Key words: delayed eruption of permanent teeth, questionnaire, X-ray examination, dental trauma, ENT pathology, bad habits, CBCT, early loss of primary teeth, allergy, burdened family history, stressor.

Some features of prevention of demineralization of hard tissues of teeth during orthodontic treatment of children with dental anomalies

Aim. To study the effectiveness of remineralization and hygienic measures in the prevention of demineralization of hard tissues of teeth when using a fixed orthodontic structure in children and teenagers with dentoalveolar anomalies. Materials and methods. We examined 150 children and adolescents with anomalies of the dentition at the age of 12 to 16 years with fixed orthodontic structures. When starting orthodontic treatment of anomalies of the dentoalveolar system in children, we proceeded from the fact that the treatment and prophylactic methods of education consisted of two stages: 1st stage – general, where they explained in detail how to carry out an individual hygienic procedure in the oral cavity with controlled brushing of the teeth; Stage 2 – specialized, which includes the features of oral care in children with orthodontic appliances in these specific conditions, in accordance with the new dental clinical situation of the oral cavity. Results. The data obtained necessitate the conditions for successful prevention of orthodontic complications during corrective therapy of dentoalveolar anomalies are remineralizing therapy, the correct choice of methods and means of individual oral hygiene.

The Effects and Mechanisms of PBM Therapy in Accelerating Orthodontic Tooth Movement.

Malocclusion is one of the three major diseases, the incidence of which could reach 56% of the imperiled oral and systemic health in the world today. Orthodontics is still the primary method to solve the problem. However, it is clear that many orthodontic complications are associated with courses of long-term therapy. Photobiomodulation (PBM) therapy could be used as a popular way to shorten the course of orthodontic treatment by nearly 26% to 40%. In this review, the efficacy in cells and animals, mechanisms, relevant cytokines and signaling, clinical trials and applications, and the future developments of PBM therapy in orthodontics were evaluated to demonstrate its validity. Simultaneously, based on orthodontic mechanisms and present findings, the mechanisms of acceleration of orthodontic tooth movement (OTM) caused by PBM therapy were explored in relation to four aspects, including blood vessels, inflammatory response, collagen and fibers, and mineralized tissues. Also, the cooperative effects and clinical translation of PBM therapy in orthodontics have been explored in a growing numbers of studies. Up to now, PBM therapy has been gaining popularity for its non-invasive nature, easy operation, and painless procedures. However, the validity and exact mechanism of PBM therapy as an adjuvant treatment in orthodontics have not been fully elucidated. Therefore, this review summarizes the efficacy of PBM therapy on the acceleration of OTM comprehensively from various aspects and was designed to provide an evidence-based platform for the research and development of light-related orthodontic tooth movement acceleration devices.

Adenoid Hypertrophy and Orthodontic Complications: An Assessment of Parental Knowledge in Saudi Arabia.

Background Adenoid hypertrophy is a common condition that can cause upper airway obstruction in children and adolescents, leading to various complications, including dental and maxillofacial abnormalities. However, parents may have limited knowledge of the orthodontic complications associated with this condition. Objective This study aimed to assess the knowledge and attitude of parents toward the orthodontic complications of untreated adenoid hypertrophy and to promote their awareness about this problem. Method This descriptive cross-sectional study involved 824 parents from all regions of Saudi Arabia. An online questionnaire was used to collect data on parents' demographics, their children's information, and their general knowledge about adenoid hypertrophy, including its symptoms, complications, and treatment. Results The study included 824 parents with a mean age of 36.78 ± 10.87 years, 73.2% of whom were women. Overall, only 6.2% (51.1 parents) had a good level of knowledge about adenoid hypertrophy. Conclusion The study highlights the importance of promoting awareness and educating parents about the orthodontic complications associated with adenoid hypertrophy. Greater awareness and understanding can help parents make better decisions for their children's health and well-being.

Treatment of dental and orthodontic complications in thalassaemia.

Thalassaemia is a quantitative abnormality of haemoglobin caused by mutations in genes controlling production of alpha or beta globins. Abnormally unpaired globin chains cause membrane damage and cell death within organ systems and destruction of erythroid precursors in the bone marrow, leading to haemolytic anaemia. The life-long management of the general health effects of thalassaemia is highly challenging, and failure to deal with dental and orthodontic complications exacerbates the public health, financial and personal burden of the condition. There is a lack of evidence-based guidelines to help care seekers and providers manage such dental and orthodontic complications. This review aimed to evaluate the available evidence on methods for treating dental and orthodontic complications in people with thalassaemia to inform future recommendations. This is an update of a Cochrane Review first published in 2019. To assess different methods for treating dental and orthodontic complications in people with thalassaemia. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register in September 2022, and we searched nine online databases and trials registries in January 2022. We searched the reference lists of relevant articles and reviews and contacted haematologists, experts in fields of dentistry, organisations, pharmaceutical companies and researchers working in this field. We searched for published or unpublished randomised controlled trials (RCTs) that evaluated treatment of dental and orthodontic complications in individuals diagnosed with thalassaemia, irrespective of phenotype, severity, age, sex and ethnic origin. Two review authors independently screened the 37,242 titles retrieved by the search. After deduplication, we identified two potentially relevant RCTs. On assessing their eligibility against our inclusion and exclusion criteria, we excluded one and included the other. We included one parallel-design RCT conducted in Saudi Arabia and involving 29 participants (19 males, 10 females) with thalassaemia. It aimed to assess the effectiveness of photodynamic therapy as an adjuvant to conventional full-mouth ultrasonic scaling for the treatment of gingivitis. The average age of participants was around 23 years. There is very low-certainty evidence from this trial that full-mouth ultrasonic scaling plus photodynamic therapy compared to full-mouth ultrasonic scaling alone may improve gingival index score and bleeding on probing after 12 weeks in people with thalassaemia. We found no studies that assessed other interventions for the various dental or orthodontic complications of thalassaemia. Although the included study showed greater reduction in gingivitis in the group treated with full-mouth ultrasonic scaling plus photodynamic therapy, the evidence is of very low certainty. The study had unclear risk of bias, a short follow-up period and no data on safety or adverse effects. We cannot make definitive recommendations for clinical practice based on the limited evidence of a single trial. Future studies will very likely affect the conclusions of this review. This review highlights the need for high-quality RCTs that investigate the effectiveness of various treatment modalities for dental and orthodontic complications in people with thalassaemia. It is crucial that future trials assess adverse effects of interventions.

Sequelae of Unreplaced Tooth Loss in Orthodontic Patients: A Cross-Sectional Study in Najran, Kingdom of Saudi Arabia.

The early tooth loss has an adverse effect on the overall well-being of an individual. The aim of the current study was to highlight the orthodontic complications of long-term tooth loss in the city of Najran. This was a cohort study of patients presenting for orthodontic rehabilitation. A total of 326 patients that presented for orthodontic rehabilitation were examined clinically and data such as age, gender, number of missing teeth, missing teeth, duration of missing teeth, tipping, and overerupted and rotated teeth were recorded. Patients that can be treated with orthodontic space closure were excluded from the study. Patients' data were analyzed using IBM SPSS Statistics and results were presented as simple frequencies and descriptive statistics. Out of 326 patients that presented for orthodontic rehabilitation, 259 patients had missing teeth with its sequelae that will demand prosthodontic rehabilitation with a prevalence rate of 79.4%. There are 97 (37.5%) males and 162 (62.5%) females with M:F ratio of 1:1.7. The age ranged from 15 to 52 years with mean ± standard deviation (28.5 ± 8.5). The age group 21-30 years constitutes the group with the highest number of missing teeth. A total number of 595 (60.2%) teeth were missing, 173 (17.5%) teeth were tipped, and 124 (12.5%) teeth were overerupted, whereas only 97 (9.8%) teeth were rotated (n = 989). Fixed orthodontic appliances (FOAs) were used for all cases with rotation and FOAs + Mini Screws were used for all cases with tipping, overeruption, and/or combinations. The dental loss was managed by prosthesis depending on patients' choice and financial capability ranging from removable/fixed prosthesis and dental implants. Orthodontic consequences of early tooth loss include tipping and rotation of adjacent teeth and overeruption of opposing teeth. Early acknowledgment of tooth replacement after tooth loss is essential in preventing long-term orthodontic adverse effects.

Cleft Orthodontic Care in Europe: A Cross-Sectional Survey.

(1) Background: Orthodontists have an important role in cleft care. Over the two decades since the Eurocleft studies, a significant improvement in healthcare systems has been achieved but there has been no critical assessment regarding the establishment of proposed standard protocols. This study aimed to describe the current provider characteristics, orthodontic appliances, services offered, orthodontic complications, and cost analysis of cleft treatment in Europe. (2) Methods: A cross-sectional 22-question online survey, accessible from January 2021 to July 2021, was sent to 214 practitioners, pertaining to provider characteristics, orthodontic appliances, services offered, orthodontic complications, and cost analysis. Descriptive statistics were calculated for each question. Fisher’s exact test was used to assess the association between categorical variables. (3) Results: A total of 79 responses from 23 European countries completed the survey (response rate = 37%), with 69 surveys being assessed after the exclusion of incomplete surveys. Rapid maxillary expansion was the preferred expansion protocol (45%). Distraction osteogenesis was the most reported alternative treatment to secondary bone grafts (19%), with private practitioners being less likely to perform these treatments (Fisher’s exact test, p = 0.001). Orthodontic services offered were, however, rather similar in the various locations of provision (hospital and/or university, private). Compromised oral hygiene (77%) was the most reported orthodontic complication. The National Health Services support the majority of cleft orthodontic care (67%) in Europe. (4) Conclusion: An apparent improvement in orthodontic healthcare provision has been achieved within Europe in the last two decades, but there are several discrepancies, namely regarding treatment timing and the appliances offered.

Microbial Diversity and Community Analysis of Dental Plaques in Orthodontic Patients Wearing Invisible Appliances and Fixed Appliances

To explore the microbial diversity and community structure of dental plaques in orthodontic patients with invisible appliances and fixed appliances and to study the differences. Ten orthodontic patients wearing invisible appliances (I) and ten wearing fixed appliances (F) were recruited. Dental plaques were collected from both buccal (B) and lingual (L) sides. Based on 16S rDNA, 40 dental plaque samples were analyzed after Illumina sequencing. The microbial diversity, abundance and evenness of the FB group were significantly higher than those of the IB and IL groups (P<0.05), while the FL group showed substantial individual differences. The community structures were generally similar among the four groups, but significant differences in the relative abundance of some bacteria were found. The IB group showed higher abundances of Actinomycetes and Rosella (P<0.05), which were considered to be involved in dental caries and periodontal diseases. Some key communities showing significant differences were significantly enriched in the FB group, including Coprobacillus, Bifidobacterium, Enterobacterium, Lactobacillus, etc.. Dental plaques in patients wearing invisible appliances and fixed appliances showed significantly different microbial abundance, diversity and composition, which may be involved in orthodontic complications such as dental caries and periodontal diseases. Orthodontic patients need strengthened measures for oral hygiene maintenance, no matter what kind of appliances they wear.

Oral piercings and orthodontic treatment: A questionnaire-based national survey.

To obtain opinions from orthodontic colleagues nationally on how they currently manage orthodontic patients with oral piercings. The secondary objectives were to assimilate the national opinions from the survey and attempt to generate educational material as an advice sheet and a patient information leaflet for the professionals and the patients respectively for the British Orthodontic Society (BOS). Cross-sectional survey. Primary and secondary care orthodontic providers. Members of the BOS. An electronic questionnaire was developed and circulated to members of the BOS to obtain their opinions on the effects of oral piercings on their patients' orthodontic treatment 'journey'. In addition, the need for the development of informative material around the management of orthodontic treatment and appliances in patients with oral piercings was explored. A total of 110 responses were received. However, only 88 respondents out of 110 attempted all the questions within the survey. There were 22 respondents who attempted it partially. We did include these partial responses well while analysing the results, since many of these offered personalised comments in the free-text boxes within the survey. The most common general complications associated with oral piercings were inflammation of the surrounding tissue and enamel/dentine wear. Moreover, orthodontic complications, reported commonly, were inadequate oral hygiene maintenance, entanglement with the orthodontic appliance causing damage and interference with retainers. Most respondents expressed the need for the development of a web-based patient information leaflet and an advice sheet as educational tool, both of which have been proposed to and agreed by the BOS before submission of this publication.

Comparison of Tooth- and Bone-Borne Appliances on the Stress Distributions and Displacement Patterns in the Facial Skeleton in Surgically Assisted Rapid Maxillary Expansion-A Finite Element Analysis (FEA) Study.

The aim of this study was to compare the reduced stresses according to Huber’s hypothesis and the displacement pattern in the region of the facial skeleton using a tooth- or bone-borne appliance in surgically assisted rapid maxillary expansion (SARME). In the current literature, the lack of updated reports about biomechanical effects in bone-borne appliances used in SARME is noticeable. Finite element analysis (FEA) was used for this study. Six facial skeleton models were created, five with various variants of osteotomy and one without osteotomy. Two different appliances for maxillary expansion were used for each model. The three-dimensional (3D) model of the facial skeleton was created on the basis of spiral computed tomography (CT) scans of a 32-year-old patient with maxillary constriction. The finite element model was built using ANSYS 15.0 software, in which the computations were carried out. Stress distributions and displacement values along the 3D axes were found for each osteotomy variant with the expansion of the tooth- and the bone-borne devices at a level of 0.5 mm. The investigation showed that in the case of a full osteotomy of the maxilla, as described by Bell and Epker in 1976, the method of fixing the appliance for maxillary expansion had no impact on the distribution of the reduced stresses according to Huber’s hypothesis in the facial skeleton. In the case of the bone-borne appliance, the load on the teeth, which may lead to periodontal and orthodontic complications, was eliminated. In the case of a full osteotomy of the maxilla, displacements in the buccolingual direction for all the variables of the bone-borne appliance were slightly bigger than for the tooth-borne appliance.

An Orthodontic Spring Coil and Soft Tissue Complication

This case report describes a scenario where a 14-year-old patient during orthodontic treatment at Solihull Hospital, West Midlands, presented with a rare soft tissue orthodontic complication. On routine examination, the spring coil from the orthodontic appliance was found to be located in the parotid gland duct. This was extracted by the oral and maxillofacial team at Solihull Hospital. The patient was followed post-operatively for any signs of sialadenitis, sialolithiasis and strictures. After 3 years of follow up, no post-operative complications were noted. CPD/Clinical Relevance: Soft tissue and orthodontic complications are common, usually due to trauma from sharp components. Clinicians should be aware of complications that can also occur.

A Rare Compound Odontoma in Mandibular Midline Region: Case Report and Literature Review

Background: Odontomas are the most common odontogenic tumors of the oral cavity. Although compound odontomas are common in the pediatric population, they are rare in the mandibular midline region during the primary dentition stage. Case Description: This article provides a rare case-report and literature review of a compound odontoma in the mandibular midline region during the primary dentition stage. A routine occlusal radiograph in an asymptomatic six-year-old patient demonstrated mixed, radiolucent-radiodense lesion apical to #N-#P (mandibular primary incisors) with intact lamina dura. Minor expansion and thinning of labial and lingual cortices were noted on cone beam computed tomographic (CBCT) images. This report discusses surgical management, histopathologic diagnosis, and 36-month clinical-radiographic follow-up of our case. Practical Implications: Compound odontomas are highly rare during the primary dentition stage in the mandibular midline (0.3%). Routine radiographs are vital for a timely diagnosis and treatment of these pathologies to prevent future orthodontic complications.

Supernumerary lateral incisors: A narrative review

Background: Although many papers on the subject of supernumerary teeth are found in the dental literature, the great majority are in the form of case reports and prevalence studies. Of the supernumerary teeth found in the maxillary incisor area, those associated with the mesiodens have received attention and extensive investigation in recent years. The less common supernumerary teeth associated with the lateral incisor appears to have been overlooked and, as far as can be ascertained from the literature, no in‑depth reviews of this particular dental anomaly have been undertaken, apart from isolated case reports. Aim: This paper reviews the current literature on characteristics, prevalence, diagnosis, and management of this problem. Materials and Methods: A thorough literature search between 1974 and 2020 was done using Scopus, PubMed, and Google Scholar databases. Results were reviewed, prioritized, and findings were compiled. The keywords of the search strategy were as follows: prevalence, case reports, supernumerary, supplemental, and lateral incisors. Only articles in English published in peer‑reviewed journals were included in the review. This review underlines the fact that a supplemental lateral incisor is a rare developmental anomaly. Results: Its prevalence among various populations falls between 0.05% and 1.59%. They occur more frequently in the maxilla than in the mandible, and the majority occur unilaterally, erupted, and of the supplemental type. Conclusion: Early diagnosis and treatment are suggested to prevent orthodontic and esthetic complications. Therefore, careful clinical and radiographic examination is essential to make a correct and rational diagnosis and treatment planning for any patient.

Treatment of dental and orthodontic complications in thalassaemia.

Thalassaemia is a quantitative abnormality of haemoglobin caused by mutations in genes controlling production of alpha or beta globins. Abnormally unpaired globin chains cause haemolytic anaemia by causing membrane damage and cell death within organ systems and destruction of erythroid precursors in the bone marrow. The life-long management of the general health effects of thalassaemia in affected individuals is a highly challenging issue in and of itself; and failure to deal with dental and orthodontic complications in people with thalassaemia exacerbates the public health, financial and personal burden posed by the condition. There exists a lack of evidence-based guidelines for care-seekers and providers to best deal with such dental and orthodontic complications in thalassaemia, which this review seeks to address. The main objective of this review was to assess different methods to treat dental and orthodontic complications in people with thalassaemia. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We searched the reference lists of relevant articles and reviews.Date of last search: 01 August 2019.We also searched nine online databases (PubMed, Google Scholar, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, Literature in the Health Sciences in Latin America and the Caribbean database, African Index Medicus, Index Medicus for South East Asia Region, Index Medicus for the Eastern Mediterranean Region, Indexing of Indian Medical Journals). We searched the reference lists of relevant articles and reviews and contacted haematologists, experts in fields of dentistry, organizations, pharmaceutical companies and researchers working in this field.Date of last search: 22 July 2019. We searched for published or unpublished randomised controlled trials for treatment of dental and orthodontic complications in individuals diagnosed with thalassaemia, irrespective of phenotype, severity, age, gender and ethnic origin. Two review authors independently screened 35,202 titles from search results. We identified four unique randomised controlled trials, of which one seemed potentially relevant. Based on closer inspection, the trial was found not to be eligible for inclusion. We did not find any relevant trials for inclusion in the review. We were unable to draw any conclusions due to the lack of available data and trials. This review highlights the need for conducting and appropriate reporting, of high-quality randomised controlled trials investigating the effectiveness of various treatment modalities for dental and orthodontic complications in people with thalassaemia.

Root reabsortion induce by orthodontic procedures

Summary: Investigation findings on tooth roots resorption are not trustworthy because they aresubmitted to some special study characteristics like sample number, important factors control,measuring methods and some characteristic elements related to research types. It’s well known thatthe grate incidence of this type of pathology occur on frontal tooth upper incisive central,incisive lateral and canines and on lower incisive laterals and canines because theirs longer andsharper roots. When through the radiography findings it is possible clearly identify the root teethtype we are able to predict the possibility of root resorption during the forces application neededto orthodontic tooth movements and also we have the capability to inform to parents and the patientabout this possible risk, but we also have the opportunity to stablish the preventive actions inorder to minimize undesirable effects of the orthodontic treatment. Key words: Teeth rootsresorption. Orthodontic treatment complications. Preventive oriented information to parents andpatients.

Preparation and antimicrobial assay of ceramic brackets coated with TiO2 thin films.

ObjectiveDifferent methods have been utilized to prevent enamel demineralization and other complications during orthodontic treatment. However, none of these methods can offer long-lasting and effective prevention of orthodontic complications or interventions after complications occur. Considering the photocatalytic effect of TiO2 on organic compounds, we hoped to synthesize a novel bracket with a TiO2 thin film to develop a photocatalytic antimicrobial effect.MethodsThe sol-gel dip coating method was used to prepare TiO2 thin films on ceramic bracket surfaces. Twenty groups of samples were composed according to the experimental parameters. Crystalline structure and surface morphology were characterized by X-ray diffraction and scanning electron microscopy, respectively; film thickness was examined with a surface ellipsometer. The photocatalytic properties under ultraviolet (UV) light irradiation were analyzed by evaluating the degradation ratio of methylene blue (MB) at a certain time. Antibacterial activities of selected thin films were also tested against Lactobacillus acidophilus and Candida albicans.ResultsFilms with 5 coating layers annealed at 700℃ showed the greatest photocatalytic activity in terms of MB decomposition under UV light irradiation. TiO2 thin films with 5 coating layers annealed at 700℃ exhibited the greatest antimicrobial activity under UV-A light irradiation.ConclusionsThese results provide promising guidance in prevention of demineralization by increasing antimicrobial activities of film coated brackets.

An unusual occurrence of bilaterally geminated mandibular second premolars resulting in premolar molarization: A case report

Gemination refers to an attempt by a single tooth bud to divide, with a resultant formation of either a large tooth with a bifid crown or two completely divided teeth throughout the crown and root. This report describes a rare case of bilateral gemination of permanent mandibular second premolar tooth giving rise to molarization of premolars. The mesiodistal width of these teeth is similar to mandibular molars, but the cervicoocclusal width is lesser than that of the molar tooth. This paper also discusses the potential orthodontic, periodontal, and endodontic complications of premolar molarization.

Linear scleroderma ‘en coup de sabre’ and an unusual response to orthodontic treatment

We present an interesting case of a patient with linear scleroderma of the ‘en coup de sabre’ type who was treated with an upper fixed appliance to align a maxillary canine. It started out as a routine straightforward case of aligning an impacted canine using a conventional technique but developed into a serious orthodontic dilemma. Clinical Relevance: The atypical response to treatment suggests a possible link between the connective tissue disorder and the orthodontic complications this case developed.
