Abstract Background: The patients’ acceptance of a treatment plan and their subsequent cooperation play a crucial role in achieving the best results in orthodontic treatments. Evidences show some personality traits such as general self-efficacy (GSE) and some dental traits such as severity of malocclusion are correlated with motivation of orthodontic treatment. These factors may predict the patients’ compliance and acceptance in using removable orthodontic appliances. This cross sectional study was conducted to assess the correlation of GSE and the severity of malocclusion with patients’ acceptance in using removable orthodontic appliances. Methods: This study recruited 50 patients aged 10-12 years who required removable orthodontic appliances. The severity of malocclusion was determined using the index of orthodontic treatment need (IOTN) before the onset of treatment and GSE of participants were assessed using GSE scale self-report. The acceptance questionnaire was proposed to the patients on first (T1), third (T2), and sixth (T3) month after the delivery of the appliance. Results: The GSE score had a statistically significant correlation with the total score of the acceptance questionnaire, subscale score of satisfaction with the appliance during eating and oral hygiene practice, duration of usage of the appliance, and interest in using it (P<0.05). The IOTN had no significant correlation with the acceptance questionnaire. Conclusions: Our findings substantiate the role of the GSES, concurrently declining the role of the IOTN in prediction of 10-12-year-old children's acceptance and cooperation in treatment of malocclusion with removable appliances.

It is necessary to know the extent of thesuccess rate of an orthodontic treatment. Assessment of malocclusion severity and treatment outcome has become avery popular object of research conducted by the PAR index. This study aims to determine the success rate oforthodontic treatment with removable appliances based on PAR Index. The research was carried out on March-May2011 with samples of patients dental models who had completed orthodontic treatment in the year 2008-2011 at theDepartment of Ortodonsia RSGMP UNHAS. Sixty six pairs of dental models fulfilled the inclusion criteria and therules of PAR Index. Percentage change in PAR score obtained by 35% in the assessment with no weighted and 36%was assessment by weighted. This results showed the level of orthodontic treatment success include into thecategory of "no change", but with a trend into the category of "a change "with a significant value ρ = 0.000 (ρ <0.05). It was concluded that there was occlusion improvements in orthodontic treatment with removable appliance,although very low and therefore need evaluation and improvement of governance maintenance carried out.

Background: Fixed orthodontic appliances, such as Edgewise and Straightwire techniques, can increase the amount of plaque retention containing Streptococcus mutans (S. mutans), which can lead to white spot lesions. Purpose: The aim of this study is to analyse the correlation of fixed orthodontic treatment with Edgewise and Straightwire techniques on the incidence of white spot lesions and accumulation of S. mutans. Methods: The samples consisted of three groups: control group (n=8), Edgewise technique group, and Straightwire technique group. We observed the samples at the sixth month and eighth month of the treatment, after the installation of the fixed orthodontic appliances. The observation of white spot lesions with caries detector was applied in all regions. Bacterial swabs were acquired in the lateral incisor region, then a bacterial culture procedure was carried out on selective media of S. mutans, and then a bacterial count was performed. The data was analysed using two-way ANOVA, the post-hoc least square differences test, and the Pearson’s correlation test. Results: The number of white spot lesions in the Edgewise group was higher than in the Straightwire group in the sixth and eighth month of treatment with insignificant difference (p>0.05). The number of S. mutans bacteria increased in all groups, but there were no significant differences (p>0.05). There was no significant relationship between the number of white spot lesions with the accumulation of S. mutans between groups (p>0.05). Conclusion: The Edgewise and Straightwire techniques increase the incidence of white spot lesions but accumulation of S. mutans with the incidence of white spot lesions has no relationship.

A 46-year-old male Caucasian with traumatically induced maxillary retrusion was referred for orthodontic treatment, eight weeks after the original fracture had occurred. Initial surgical reduction and fixation had been successful, when a second traumatic episode was encountered. This resulted in a further degree of posterior maxillary displacement, which was resistant to further surgical reduction. The resulting Class III malocclusion was treated using maxillary protraction headgear, in conjunction with removable orthodontic appliances and intermaxillary traction. Appliances were worn full time and inter-arch correction was achieved in six months. The resulting occlusion proved to be stable following the cessation of active treatment.

Summary. Modern protocols on providing orthodontic care of children with anomalies and secondary dento-maxillaire deformities include the use of functional- guiding and mechanically-operated orthodontic equipment based on specific clinical indications. At the same time, the issues of orthodontic treatment of dento-maxillaire anomalies complicated by dentition defects still remain controversial, as the vast majority of functionally-guiding and mechanically-operated orthodontic equipment does not provide simultaneous replacement of dentition defect, whereas methods of pediatric prosthetics are often limited by the use of claspless removable laminar prostheses. Their functional efficiency is low due to insufficient fixation and the need for periodic replacement due to the growth of jaws in accordance with the age and physiological development of a child’s body. The use of traditional fixed bridge prostheses during the period of jaws growth is unacceptable, whereas the manufacture of split bridge prostheses with an intermediate part in the form of sliding elements, movably interconnected, as well as cantilever bridges, is limited by dentition due to the removal of only one tooth. Orthodontic appliances that meet these requirements, should be used to replace dentition defects, combined with dento-maxillaire anomalies in each period of formation of the dento-maxillaire system, which determines the relevance of our research. Goal. To increase the effectiveness of comprehensive treatment of children with dento-maxillaire anomalies, complicated by dentition defects of the frontal area with the use of a prosthetic appliance of our own design. Materials and methods. To achieve this goal, we examined 115 children aged from 5 to 17 years with dentition defects of the frontal area, who applied to the Department of Orthopedic Dentistry and Orthodontics, Kyiv Medical University. Of these, orthodontic treatment was performed in 64 patients with the use of removable and non-removable orthodontic appliances, including a prosthesis appliance of our own design: «Prosthesis appliance for upper jaw expansion » Ukrainian patent for a utility model № 145538 dated 28.12.2020, which is fixed using orthodontic bands and temporary fixation cement on the second temporary molars. The appliance has a plastic base with a screw, with which, if necessary, it is possible to influence the growth of the jaw. It also has artificial teeth in the frontal area, which are connected to the base, and do not inhibit the growth of the frontal segment of the upper jaw. Results. According to the results of the research it is determined that for each period of formation of the dento-maxillaire system with dento-maxillaire anomalies complicated by dentition defects it is reasonable to apply a personalized approach when conducting psycho-emotional preparation for treatment, oral cavity sanation, placing on myogymnastic exercises and appropriate orthodontic treatment combined with pediatric prosthetics. Traditional removable and non-removable orthodontic appliances as well as appliances of our own design were used to treat this group of people. According to the results of the treatment, the use of a fixed orthodontic appliance of our own design in children of young and middle age, which restores the function of biting food, allows to replace the dentition defect and meet the aesthetic requirements of patients, as well as to conduct continuous orthodontic treatment due to impossibility to remove the appliance. Indications for the use of this prosthesis appliance is the absence of 1 to 4 front teeth with the possibility of correcting the transversal size of the jaws. Our proposed prosthesis appliance meets the requirements and is easy for patients to use. Conclusions. Indications for the use of the prosthesis appliance of our own design is the absence of 1 to 4 front teeth with the possibility of correcting of the transversal size of the jaws. The use of a non-removable prosthesis appliance of our own design in children of young and middle age, which restores the function of biting food, allows to replace the dentition defect, meet the aesthetic requirements of patients, and to conduct continuous orthodontic treatment.

Pmma Resin

Removable orthodontic appliances made of poly methyl methacrylate (PMMA) resin are commonly used after complete orthodontic treatment to keep teeth in the right position and prevent the shift out from the alignment. The use of these appliances can place patients at increased risk of dental caries through the biofilm accumulation ofStreptococcus mutans, caries-associated bacteria, on the surfaces of appliance themselves. Moreover, their rough surfaces or intrinsic porosities of PMMA enhance a condition for plaque aggregation, altering the oral microflora and limiting the washing out action of saliva on teeth and mucosal tissues, subsequently bringing about enamel demineralization and gingival inflammation. Cleaning by brushing or using chemical disinfectants is necessary for hygiene maintenance of the appliances, but requires patient cooperation, which is uncertain. Vanillin is a natural phenolic aldehyde which is used widely as a flavoring agent in various foods. It has been reported by many studies to exhibit antimicrobial activity. The aim of the present study was to evaluate antimicrobial property of vanillin-incorporated orthodontic PMMA resin onS. mutansbiofilm formation. The self-curing orthodontic PMMA resin samples (SCG Chemicals, Thailand) were prepared according to the percentage of vanillin incorporation (0%, 0.1% and 0.5% vanillin). Another group of commercial resin samples without vanillin (Dentsply Caulk, USA) was prepared in the same manner. All samples were coated with sterile unstimulated saliva collected from three healthy adult volunteers at 37 °C for 60 min. TheS. mutansbiofilm formation was done with the 107colony forming unit (CFU)/m of bacterial suspension in 96-well plate and incubated at 37°C in 5% CO2 atmosphere for 24 h. The amount of biofilm was quantified by Cell Counting Kit WST-8 (Dojindo Molecular Technologies, USA) at 450 nm. All tests were performed in triplicate on three separate occasions. One-way ANOVA and Turkey’s test were used for the statistical analysis. A significant inhibitory effect was observed in 0.5% vanillin incorporated samples at 48 h compared with 0% vanillin and commercial samples. The percentage of biofilm reduction was 30%. In conclusion, the incorporation of vanillin to self-curing orthodontic PMMA resin could significantly inhibit biofilm formation ofS. mutans. Using this PMMA resin, removable orthodontic appliances with antimicrobial property can be applied to prevent dental caries or tooth demineralization in orthodontic patients.

Background: During the course of fixed orthodontic therapy, it is difficult to maintain high standard oral hygiene care by mechanical tooth cleaning only. Therefore, mouthwashes are commonly used as adjunct for mechanical tooth cleaning. Most of the mouthwashes are chemicals and have a wide range of side effects. Plant extracts have stood the test of time as safe inexpensive and available remedy for providing general health care. Objective: The present study attempted to evaluate the efficacy of gargling with aqueous extract of Dandelion (Taraxacum officinale) on the oral hygiene status of patients wearing fixed orthodontic appliances. Methods: Eleven male patients undergoing orthodontic treatment with fixed appliances were recruited in the study. All patients were given the same oral hygiene regimen during the study period. Clinical evaluation of OPI (orthodontic plaque index) and salivary streptococcus mutans count were recorded at the first activation visit (three weeks after placement of the orthodontic appliances) which considered the baseline visit and after one week of gargling with the extract. The data were statistically analyzed with SPSS (version 21) using Paired Samples t-test. Result: The results of the statistical analysis revealed that, there were highly significant reductions in both OPI and salivary streptococcus mutans count after one week gargling with aqueous extract of Dandelion (Taraxacum officinale). Conclusion: The present finding concluded that, aqueous extract of Dandelion (Taraxacum officinale) could be use as a promising ingredient in manufacturing mouthwashs and other dental supplies that contribute in maintaining good oral hygiene during the course of orthodontic treatment with fixed appliances.
