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...

Placement of fixed appliances is still unfortunately linked with a high risk of developing white spot lesions, in spite of advances in orthodontic materials and treatment techniques [1,2]. During orthodontic treatment, plaque accumulation is frequently inevitable around the brackets because of inadequate oral hygiene which is very common in pubertal people [2]. Dental plaque is a biofilm produc...

INTRODUCTION Nickel, a primary component of orthodontic appliances, causes more allergic reactions than all other metals combined and can initiate a wide range of hypersensitivity reactions in susceptible subjects. The purpose of this study was to compare pretreatment and treatment levels of nickel in the urine of orthodontic patients wearing fixed appliances. METHODS Urine specimens were col...

OBJECTIVE To assess parents' and caregivers' view of the first twelve months of adolescents' orthodontic treatment with fixed appliances and to assess the evaluative properties of the Brazilian version of the Parental-Caregiver Perceptions Questionnaire (P-CPQ) in the orthodontic setting. METHODS Data from a sample of 96 parents and caregivers of adolescents undergoing orthodontic treatment w...

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 ...

Objective: To evaluate the effects of fixed orthodontic treatment on gingival health. Materials and methods: In the present study 30 orthodontic patients under fixed mechanotherapy mean aged 19.82 years were selected. The selection criteria were: Treatment that consisted of full-mouth fixed orthodontic appliances. Exclusion criteria included patients with systemic disease, are on antibiotics or...

STATEMENT OF THE PROBLEM Fixed orthodontic appliances predispose patients to dental caries. Use of mouthrinses has been introduced as the effective way for reducing dental plaque accumulation. PURPOSE The aim of this study was to compare the effects of Persica mouthwash and Chlorhexidine (CHX) on colonization of Streptococcus mutans (S. mutans) on fixed orthodontic O-rings. MATERIALS AND ME...

Decalcification of enamel, appearing as white spot lesions (WSLs), around fixed orthodontic appliances is a major challenge during and after fixed orthodontic treatment by considering the fact that the goal of orthodontic treatment is to enhance facial and dental esthetic appearance. Banded or bonded teeth exhibit a significantly higher rate of WSLs compared to the controls with no braces as fi...
