The site prevalence and intra-oral density of Candidal organisms may be increased by local factors including prostheses. However, whether significant changes in Candidal carriage occurs with denture wearing is not clearly established. This study employed the imprint culture technique to assess the effects of fixed and removable orthodontic appliances on oral carriage, site prevalence and intra-oral density of Candida in adolescents. Moreover, alterations in plaque distribution were measured. Groups of 12–16 year olds without or wearing fixed and removable appliances were studied. Imprint cultures were taken from six intra-oral sites and colony counts recorded after 48 hours incubation on selective media. Plaque scores were recorded from non-appliance and removable appliance wearers. The prevalence of Candidal carriage in the groups was not significantly different being 46 per cent of non-appliance, 51 per cent of fixed appliance and 52 per cent of removable appliance wearers. However, the prevalence of Candidal recovery at some sites and Candidal densities at all sites were significantly increased in both fixed and removable appliance wearers. Thus orthodontic appliances may predispose to Candidal proliferation in oral carriers. However, the results do not permit the conclusion that appliances may change non-carriers of Candida to carriers. Plaque distribution was significantly altered in removable appliance wearers when compared with non-appliance wearers as a result of increases in palatal plaque scores. These findings again emphasize the particular need for oral hygiene instruction in patients wearing appliances or partial prostheses.

The success of orthodontic treatment, particularly with removable orthodontic appliances not only relies on theexpertise of the clinician, but also highly depends on the patient's own. 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.

OBJECTIVES: To determine the frequency of emergencies in patients with fixed and removable orthodontic appliances at tertiary care dental hospital. METHODOLOGY: A questionnaire was designed for this descriptive cross-sectional study to be filled by the clinician (L3/L4 FCPS resident) at the end of addressing every orthodontic emergency. Sampling was done under consecutive non-probability protocols. Descriptive statistics were applied to determine the frequency of different orthodontic emergencies, and Pearson’s chi-square test was applied to determine association of emergencies with gender and etiology of emergency (patient related vs operator related). Data was analyzed on SPSS version 20. RESULTS: A total of 175 patients reported with orthodontic emergencies. The sample comprised 38.3% males and 61.7% females. Most frequent orthodontic emergency reported was deboned brackets in fixed appliances, while the most common emergency in removable appliances was traumatic PNAM. A statistically significant association (Pearson’s Chi Square=4.74, Cramer’s V=0.165, p=0.029) was seen for removable and fixed appliance emergencies with males and females. CONCLUSION: Most frequent fixed appliance orthodontic emergencies were deboned brackets while for removable appliance emergencies were trauma due to PNAM. Emergencies with removable appliances were mostly due to the operator related factors, while in fixed appliances patient related factors were dominating.

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 Background Removable orthodontic appliances due to plaque accumulation and oral microbe colonization, might be associated with intraoral adverse effects on enamel or periodontal tissues. The present systematic review was carried out to evaluate both qualitatively and quantitatively the microbiological changes occurring during orthodontic therapy with removable orthodontic appliances. Methods PubMed, Cochrane, EMBASE, Web of Science, Scopus, Ovid Medline, Dentistry & Oral Sciences Source and Vita-Salute San Raffaele University databases were searched. The research included every article published up to December 2018. The Preferred Reporting Items for Reporting Systematic reviews and Meta Analyses (PRISMA) protocol and the ‘Swedish Council on Technology Assessment in Health Care Criteria for Grading Assessed Studies’ (SBU) method were adopted to conduct this systematic review. Results The current study has moderate/high evidence, according with SBU method. It demonstrates that removable appliances do influence the oral microbiota, with significant alterations just 15 days after the beginning of therapy, independently from the type of appliance. Furthermore, the levels of oral pathogens decrease significantly or even returned to pre-treatment levels several months later the therapy end. Conclusions This review suggests that orthodontic treatment with removable appliances might not induce permanent changes to oral microflora.

Anterior crossbite is relatively a common presentation in the mixed dentition stage. If left untreated, it can lead to a host of problems and may complicate future orthodontic treatment. One of the major difficulties in performing anterior crossbite correction in young children is treatment compliance. In most cases, poor compliance is due to the unacceptability of the removable appliance used. This article describes three cases of successful correction of anterior crossbite of patients in mixed dentition using short-span wire-fixed orthodontic appliances. This sectional appliance provides an alternative method of correcting anterior crossbite of dental origin and offers many advantages compared to the use of removable appliances.

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.

ABSTRACT Objective:  To compare patients’ perceptions of fixed and removable appliance therapy for correction of anterior crossbite in the mixed dentition, with special reference to perceived pain, discomfort, and impairment of jaw function. Material and Methods:  Sixty-two patients with anterior crossbite and functional shift were recruited consecutively and randomized for treatment with fixed appliances (brackets and archwires) or removable appliances (acrylic plates and protruding springs). A questionnaire, previously found to be valid and reliable, was used for evaluation at the following time points: before appliance insertion, on the evening of the day of insertion, every day/evening for 7 days after insertion, and at the first and second scheduled appointments (after 4 and 8 weeks, respectively). Results:  Pain and discomfort intensity were higher for the first 3 days for the fixed appliance. Pain and discomfort scores overall peaked on day 2. Adverse effects on school and leisure activities were reported more frequently in the removable than in the fixed appliance group. The fixed appliance group reported more difficulty eating different kinds of hard and soft food, while the removable appliance group experienced more speech difficulties. No significant intergroup difference was found for self-estimated disturbance of appearance between the appliances. Conclusions:  The general levels of pain and discomfort were low to moderate in both groups. There were some statistically significant differences between the groups, but these were only minor and with minor clinical relevance. As both appliances were generally well accepted by the patients, either fixed or removable appliance therapy can be recommended.

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.

Aim: To evaluate the prevalence and hygiene habits of 13-19 years-old adolescent users of removable orthodontic appliances (ROA) and to determine hygiene methods for the appliances prescribed by dentists, in the city of Pelotas. Methods: The study had two stages. The first stage was a telephone interview with dentists. Dentists were interview by telephone calls in order to obtain information regarding the hygiene methods for cleaning acrylic appliances. Second stage was a cross-sectional study performed with schoolchildren. Children from public and private schools with secondary level were included in the sample. A questionnaire was applied to the students using any type of ROA. Questionnaires included demographic information and behavioral characteristics. Data collected were subjected to Chi-square test and logistic regression. Results: The prevalence of children using ROA was 5.4%. Students (89.7%) and dentists (47.2%) reported to prefer mechanical methods to clean their ROA. Cleaning with soup, hydrogen peroxide or effervescent tabs were less used. High frequency of use was associated with higher frequency of hygiene on the ROA. Conclusions: The prevalence of schoolchildren using removable appliances was low. The common cleaning method used by children and prescribed by dentists was mechanical. Hygiene frequency was significantly associated with the routine of use of the appliance and with the type of hygiene method.
