Microbiological Evaluation of 0.2% Chlorhexidine Gluconate Mouth Rinse in Orthodontic Patients

Abstract

Objective: To assess the effectiveness of 0.2% chlorhexidine gluconate mouth rinse on Streptococcus mutans and lactobacilli in orthodontic patients with fixed appliances. Materials and Methods: Twenty patients, aged 13-18, with fixed orthodontic appliances participated in the study. The levels of S mutans and lactobacilli in saliva samples were evaluated at four stages: at the beginning of the orthodontic treatment, at least 2 weeks after the bonding of brackets, 1 week after the introduction of 0.2% chlorhexidine gluconate mouth rinse, and at the fourth week. The changes in S mutans and lactobacilli levels were analyzed via Wilcoxon test. Results: Increases in bacterial levels of S mutans and lactobacilli were detected after the orthodontic appliances were bonded. A significant decrease in S mutans levels was observed 1 week after the introduction of chlorhexidine mouth rinse. Conclusions: An 0.2% chlorhexidine gluconate mouth rinse decreased S mutans levels, but had no effect on lactobacilli levels.

Efficacy of fluoride varnish for prevention of white spot lesions during orthodontic treatment with fixed appliances: A systematic review study

“…The benefits of using antimicrobial agents for the control of gingivitis have been widely discussed in the literature, and at present, CHX is considered the most effective agent for this purpose (Sari and Birinci, 2007). CHX has the capacity to prevent biofilm formation, which is one of the main etiological factors of caries disease.…”

Effects of chlorhexidine (gel) application on bacterial levels and orthodontic brackets during orthodontic treatment

“…Dental biofilm formation is a result of an increase in the number of microorganism that is directly related to dental caries, particularly Streptococcus mutans (S. mutans) (2)(3)(4)(5)(6)(7). Dental biofilm formation on tooth surfaces is 2-3 times higher in orthodontic patients than high plaque-forming adults with no orthodontic treatment (1).…”

Eficacia Del Uso Del Enjuague De Clorhexidina Durante El Tratamiento De Ortodoncia

“…Las presentaciones son diversas y contemplan opciones tales como enjuagues bucales, geles o dentífricos, cuyo efecto depende en mayor medida de la cooperación del paciente. 32,33 Adicionalmente, de acuerdo con algunos reportes en la literatura, medidas adicionales como el uso de cepillos eléctricos con acción rotatoria en pacientes con tratamiento de ortodoncia remueven más placa y reducen la gingivitis más efectivamente que el cepillado manual. 34,35 Es necesario desarrollar programas preventivos que refuercen la calidad de los tratamientos y disminuyan los costos tanto biológicos como econó-micos para el paciente y puedan cumplir con los objetivos estéticos que cada vez son más frecuentemente buscados por los pacientes.…”
