SummaryOrthodontic treatment of dentoalveolar anomalies is car-ried out using fixed and removable appliances, which af-fects the homeostasis of the oral cavity and increases the risk of developing carious lesions of the enamel. Purpose of the study: comparative assessment of the level of oral hygiene and the prevalence of enamel carious lesions at the stage of orthodontic treatment using removable and non-removable appliances. Materials and methods:90 patients aged 18 to 35 years were examined: 45 patients of the 1st group, who were treated with aligners, and 45 patientsof the second group, who were treated with a bracket system. In all patients, the level of oral hygiene was determined by the OHI-S (Green-Vermillion) index, as well as the level of CPU before and after 12 months of orthodontic treatment. Results: before the start of orth-odontic treatment, the OHI-S index in patients of the first and second groups was 0.86±0.67 and 0.89±0.74 points, respectively. After 12 months, there was a deterioration in the parameters of oral hygiene to a greater extent in patients of the second group who were treated with a fixed technique: the OHI-S index was 1.98±0.79 points. The value of the CPU index before the start of orthodontic treatment in patients of the first and second groups was 7.1±1.32 and 6.9±1.46, respectively. After 12 months of orthodontic treatment, there was an increase in the CPU index in the studied persons of the second group, who were treated with a bracket system: the CPU index was 13.6±1.78. In patients of the first group, the CPU indica-tor practically did not change and amounted to 7.9±1.25. Conclusion: with high caries susceptibility and the pre-sence of non-carious enamel lesions, orthodontic treat-ment with removable appliances should be preferred in order to avoid the development of complications.

The progression of proximal caries on canines, premolars and molars has been studied among 129 children treated with removable orthodontic appliances. The registration of carious lesions was performed on posterior bitewing radiographs taken before and after the orthodontic treatment. The children in this investigation showed a higher proximal caries progression than children treated with fixed orthodontic appliances where bands had been used. However, in comparison with caries data from epidemiological investigations in children of similar ages from the same area no difference was noted.

Abstract Background Remote digital monitoring during orthodontic treatment can help patients in improving their oral hygiene performance and reducing the number of appointments due to emergency reasons, especially in time of COVID-19 pandemic where non-urgent appointments might be discouraged. Methods Thirty patients scheduled to start an orthodontic treatment were divided into two groups of fifteen. Compared to controls, study group patients were provided with scan box and cheek retractor (Dental Monitoring®) and were instructed to take monthly intra-oral scans. Plaque Index (PI), Gingival Index (GI), and White Spot Lesions (WSL) were recorded for both groups at baseline (t0), every month for the first 3 months (t1, t2, t3), and at 6 months (t4). Carious Lesions Onset (CLO) and Emergency Appointments (EA) were also recorded during the observation period. Inter-group differences were assessed with Student's t test and Chi-square test, intra-group differences were assessed with Cochran’s Q-test (significance α = 0.05). Results Study group patients showed a significant improvement in plaque control at t3 (p = 0.010) and t4 (p = 0.039), compared to control group. No significant difference was observed in the number of WSL between the two groups. No cavities were detected in the study group, while five CLO were diagnosed in the control group (p = 0.049). A decreased number of EA was observed in the study group, but the difference was not significant. Conclusions Integration of a remote monitoring system during orthodontic treatment was effective in improving plaque control and reducing carious lesions onset. The present findings encourage orthodontists to consider this technology to help maintaining optimal oral health of patients, especially in times of health emergency crisis.

Many scientists were engaged in the study of dentition anthropometry in patients before and after orthodontic treatment. The most common orthodontic device for the treatment of malocclusion class III is a regulator of Frenkel type III. We have proposed a new orthodontic device for the treatment of patients with malocclusion class III and premature removal of temporary molars. Aim - to compare changes of dentitions in children aged 6-12 before and after orthodontic treatment of malocclusion class III using the device of own design and regulator of Frenkel type III. Materials and methods. 110 patients at the age of 6-12 years with malocclusion class III were treated with the use of removable orthodontic curative devices. Anthropometry of dentitions was conducted before and after the treatment. Results. After applying the new diagnostic and treatment algorithm, the duration of orthodontic treatment of patients with malocclusion class III reduced by 1.3 times. The children's quality of life have improved after orthodontic treatment. Conclusion. In case of children aged 6-12 years with malocclusion class III associated with premature removal of temporary molars, it is necessary to use the device of our design. This will give the opportunity not only to fix the dento-facial abnormality, but also to restore the functions of chewing, swallowing and speech.

Search of the literature has failed to reveal any previous objective analysis of changes produced by treatment. Using the Occlusal Index a survey was carried out on study models of patients accepted for treatment in the Orthodontic Department of The London Hospital, over a nine year period (1963–71). The spread of severity of malocclusion of these patients was assessed to see if there had been a gradation in severity through the period as reflected by a trend in the yearly mean values of the Occlusal Index scores. Analysis of the results failed to show any discernible trend. The Occlusal Index was used to gain an objective and quantitative assessment of change produced by treatment and subsequently to correlate this change with the use of fixed and removable appliances. A slight but statistically significant difference was apparent in treatment results. Fixed appliance cases showed superiority to removable appliance cases, producing a better end result and greater degree of improvement. The difficulties in the use of application of the Occlusal Index to British cases are discussed and suggestions are made for modification.

Objective: This work aims to use new spectroscopic and radiographic methods to study the dental hard tissue erosion and abfraction, as these lesions are actually quite difficult to be diagnosed in clinical practice. Material and Methods: This in vivo study was conducted on 60 patients with early erosion and 60 patients with abfraction at the cervical area by means of laser-induced fluorescence (LIF) and multilayer spiral computed tomography (MSCT). Results: In comparative dental hard tissues studies LIF spectra from intact and affected areas, it was noted multidirectional fluorescence intensity dependence between areas affected by abfraction and intact areas. MSCT technique allowed assessing the degree of damaged areas, especially at deeper stages. Conclusion: Although LIF and MSCT methods presented limitations, it was shown their effectiveness in the diagnosis of abfraction and erosion by detecting changes in the morphological structure as well as in the chemical and mineral composition of affected dental hard tissues. So LIF and MSCT methods can be successfully used in order to develop new medical devices which will provide most accurate clinical diagnose of different stages of dental erosion and abfraction.KEYWORDSFluorescence spectroscopy; Spiral computed tomography; Tooth demineralization; Tooth erosion.

The dental study casts of 150 consecutively completed removable appliance cases were examined before and after orthodontic treatment using the PAR index. Eighty-nine per cent were classified either as ‘improved’ or ‘greatly improved’. Of the 16 cases classified as ‘worse, no different’, six were mixed dentition cases with limited treatment objectives (which were successfully achieved) and three were permanent dentition cases where only one tooth was being aligned. Using predefined criteria removable appliances were shown to be most effective in treating cross-bites, ectopic tooth position, anterior spacing, and overjet, and less effective in treating crowding, rotations, and molar relationships.

Abstract Introduction. Numerous clinical symptoms found in patients with temporomandibular disorders include non-carious lesions, such as V-shaped lesions, wear facets, enamel cracks, and impressions on the tongue or changes in the buccal mucosa. In addition, loosening and dislocation of teeth may occur. Aim. The aim of the study was to obtain a clinical assessment of the prevalence and severity of non-carious lesions of dental hard tissues (attrition and abrasion) in patients treated for functional temporomandibular disorders. Material and methods. The clinical research was performed among 45 patients of both genders, aged 16-38 years, treated at the Department of Functional Masticatory Disorders at the Medical University of Lublin, Poland. The study group consisted of 30 patients with diagnosed temporomandibular disorders. The control group included 15 individuals with no diagnosed temporomandibular disorders. The control group was selected using the method of analogues (considering age, gender and dental status). The examinations were performed before the treatment and twelve weeks after its beginning. Results. The study found significantly higher values of the prevalence and severity of attrition in the patients group, in comparison with the control group (p < 0.05). In the case of abrasion, higher values of the studied variables of prevalence and severity of lesions in the patients, compared to controls, were also found, but the differences were not statistically significant (p > 0.05). Conclusions. Attrition occurs more frequently and is more severe in patients with diagnosed temporomandibular disorders than in those without such diagnosis. However, no significant differences have been found in the prevalence and severity of abrasion in both groups.

Introduction: During orthodontic treatment, the risk of gingivitis, periodontal disease and dental caries is increased. For good gingival health during orthodontic therapy, patients must be educated about the importance of daily oral hygiene and also given instructions on plaquecontrol techniques and how to use plaque removal devices properly. Objectives: The aim of this study was to present risk factors for gingivitis during treatment with fixed orthodontic appliances as well as methods and resources for prevention of this widespread disease. Conclusion: Maintaining proper oral hygiene is of great benefit not only for gingival health but also for the success of orthodontic treatment and maintenance of treatment results. Beside healthy gingiva, favorable habits in oral hygiene remain life-long.

Resistance of tooth enamel to aggressive effect of metabolic by-products of oral cavity microorganisms is provided by fluoroapatites of enamel surface layers. The patients were divided into two groups: control group (30 females) and experimental (observa-tion) group (30 females). In control group, the traditional method of caries prevention was used, which included professional teeth cleaning, mouthwash with physiological solution (0.9%) of sodium chloride after meals, hygienic teeth brushing by a standard method twice a day. Females of experimental group underwent professional teeth cleaning, treatment of teeth with the drug product containing sodium fluoride to in-crease the resistance of hard tissues of teeth, silver nitrate and decamethoxin, rinsing with standardized decamethoxin solution. Various indices are used in modern den-tistry to evaluate oral hygiene status. Index estimation provides quantitative charac-teristics of static status of oral hygiene. Their values enable to suggest the course of inflammatory-destructive or dystrophic process and its severity, to evaluate treatment efficacy and quality of regular check-up of a particular patient or dispensary cases. The study demonstrated significant positive clinical efficacy of the drug product used to increase resistance of dental hard tissues. In particular, patients using the pharma-ceutical preparation to improve the resistance of dental hard tissues, had significantly lower values of Fedorov-Volodkina’s Index, Greene-Vermillion Index (Oral Hygiene Index- Simplified), Patient Hygiene Performance (PHP) Index as compared to the control group.
