INTRODUCTION In this study, we evaluated the effects of orthodontic appliances and an extracted maxillary first premolar on the esthetic evaluation of a smiling face according to the perceptions of orthodontists and laypeople. METHODS Standardized oblique photographs of a young woman with a pleasing smile were taken. The photos were edited by using digital imaging software to produce 10 combi...

Fixed vestibular appliances decrease the "self-cleansing" action of saliva and promote aggregation of dental plaque by disturbing the salivary flow field on tooth surfaces, leading to a higher prevalence of enamel demineralization and periodontal diseases. In the current study, we investigated the salivary dynamic characteristics of plaque retention and periodontal status around appliances duri...

One of the commonest problems of patients undergoing orthodontic treatment with fixed appliances is the development of enamel demineralization. In the study of Gorelick et al. (1982) 1 50% of the patients undergoing orthodontic treatment with fixed appliances developed white spot lesions compared to 25% of the non-orthodontic patients. These initial lesions can be visible as soon as the fourth ...

Using PAR index / Peer Assessment Rating Index / effectiveness of orthodontic treatment was assessed in the group of patients treated with fixed and removable appliances. The group consisted of 83 patients after the end of the active phase of treatment. 34 patients were treated with removable appliances and 49 patients were treated with fixed appliances. Patients came from three orthodontic wor...

Traditionally oral appliances i.e. removable orthodontic appliances, bite splints and snoring / sleep apnea appliances are made with alginate impressions and wax registrations. Our aim was to describe the process of manufacturing customized oral appliances with a new technique i.e. rapid tooling method. The appliance should ideally be custom made to match the teeth. An orthodontic patient, sche...

The purpose of this literature review was to screen the valuable published articles regarding to the impacts of mini-implants on orthodontic science, briefly. The searching category was performed on the Pubmed using MeSH words such as "dental (mini) implants, orthodontic anchorage procedures, and orthodontic appliances." After preliminary sketch, they were grouped as follow: Those evaluating (a...

Objective: To evaluate the esthetic perception of different appliances by Brazilian lay adults and its influence in the attributed value of orthodontic treatment, considering evaluators’ socioeconomic status, age and gender.

Young athletes with ever-changing transitional dentitions and those wearing fixed orthodontic appliances can benefit from custom-formed protective mouthguards. Modifications of the traditional vacuum-forming method are useful to fabricate mouthguards for such patients and extend the useful life of these devices. The purpose of this case report is to document fabrication of custom-formed protect...

Orthodontic appliances often provide good retention sites for oral microorganisms. This leads to a high cariogenic challenge in saliva. The purpose of this study was to evaluate saliva Streptococcus Mutans and Lactobacilli levels in different 5 phase on 24 patients need to both removable and fixed orthodontic application. So we had a possibility to determinate of the S. Mutans and Lactobacilli ...

INTRODUCTION This purpose of this study was to document and investigate changes in periodontal pathogen levels before, during, and after orthodontic treatment in adolescents. METHODS DNA gene probe analysis was used to quantify the levels of 8 periodontal pathogens before, during, and after treatment with fixed orthodontic appliances in 190 concurrently treated adolescent orthodontic patients...
