“…26 In healthy individuals, these microorganisms coexist in equilibrium with the host, but environmental changes and microbial imbalances may originate infections. 1 For example, brackets and orthodontic bands induce specific changes in the oral environment, such as a lower pH and an increase of bacterial plaque, 1 higher levels of S. mutans 1,22 and an increase in the number of Lactobacilli species. 1,24 This study found that biosafety procedures adopted in academic settings are not efficient to reduce the risk of infection.…”

Objective: To evaluate bacterial contamination of orthodontic pliers used in an academic setting. Methods: Thirty-four pliers were selected -17 band remover pliers and 17 bird beak pliers. The control group was composed of 3 previously autoclaved pliers of each model. After use, the pliers in the experimental group were immersed in 10 ml of brain-heart infusion (BHI) culture medium for 2 minutes, incubated at 37º C for 24 to 48 h and seeded in duplicates in different agar-based solid culture media to detect and identify microbial agents. Results: Microbiological analyses revealed that there was contamination in both types of orthodontic pliers. Several bacteria were detected, predominantly staphylococcus and isolated Gram-positive (G+) cocci. The band remover pliers had a greater contamination rate and mean values of 2.83 x 10 9 and 6.25 x 10 9 CFU/ml, with variations according to the type of culture medium. The 139 pliers also had all types of bacteria from the oral microbiota at values that ranged from 1.33 x 10 8 to 6.93 x 10 9 CFU/ml. The highest mean value was found in the medium to grow staphylococci, which confirmed, in certain cases, the presence of Staphylococcus aureus, which are not part of the normal oral microbiota but are usually found in the nasal cavity and on the skin. Conclusion: Orthodontic pliers were contaminated as any other dental instrument after use in clinical situations. Therefore, they should undergo sterilization after each use in patients. Abstract

“…The dental literature suggests that orthodontic treatment with fixed appliances leads to an increased plaque accumulation 1 and elevated levels of mutans streptococci and lactobacilli, 2,3 which are considered the main pathogens in dental caries. This can increase the risk of decalcification, which can involve up to 50% of patients, and can lead to the development of caries.…”

Objective: To examine the difference in the adhesion of Streptococcus mutans to three different types of orthodontic brackets and the effect of the presence of an early salivary pellicle and Streptococcus sanguis on adhesion. Materials and Methods: Three adhesion experiments were performed using stainless steel, ceramic, and plastic orthodontic brackets. In the first experiment a clinical strain of S mutans adhered to the three different types of brackets (n ϭ 6 for each). For the second, the brackets were treated with saliva before adhesion of S mutans (n ϭ 6 per type of bracket). Finally, the third experiment concerned saliva coated brackets (n ϭ 6 per type of bracket), but before S mutans, S sanguis bacteria were allowed to adhere. The bacteria were always allowed to adhere for 90 minutes in all the experiments. Adhesion was quantitated by a microbial culture technique by treating the brackets with adhering bacteria with trypsin and enumerating the total viable counts of bacteria recovered after cultivation. Results: There were consistently no differences in the adherence to stainless steel, ceramic, or plastic brackets. The presence of an early salivary pellicle and S sanguis reduced the number of adhering S mutans to all three types of brackets. Conclusions: Adhesion of bacteria to orthodontic brackets depends on several factors. The presence of a salivary pellicle and other bacterial species seem to have a significant effect on the adhesion of S mutans, reducing their numbers and further limiting any differences between types of brackets.

“…3,4 La literatura ha demostrado que los tratamientos de ortodoncia incrementan la acumulación de placa y la colonización bacteriana por lo que resultan afectados los tejidos periodontales y dentarios. [21][22][23][24][25] Si se permite el crecimiento de esta placa aparecerán algunos cambios cuyos resultados dan lugar al establecimiento de la gingivitis tras dos a tres semanas.…”

RESUMENObjetivo: Determinar la eficacia de la clorhexidina sobre la cantidad de placa dental presente en sujetos adultos, usuarios de aparatología ortodoncica y residentes en el área metropolitana de Bucaramanga que eran atendidos en las clínicas de ortodoncia de la universidad Santo Tomas, durante el segundo semestre del año 2007. Materiales y métodos: Ensayo clínico controlado realizado con 60 sujetos adultos en tratamiento de ortodoncia. Se estableció el índice de placa OPI (Ortho-Plaque Index) y el índice gingival (GI Index). El grupo intervenido recibió 10 ml de Digluconato de Clorhexidina (0,2 %), que se utilizó en forma de enjuagues dos veces por día, sin interrupciones por quince días. Resultados: Los sujetos expuestos a la intervención tenían 2.2 veces más de probabilidad IC (1.6 a 3.3) de tener un índice OPI cuyos valores reflejaban una buena higiene oral. Conclusiones: Se podría afirmar que la exposición de los sujetos, con tratamiento de ortodoncia, al Digluconato de Clorhexidina (0.2%), por un periodo de quince días, disminuyó la placa dental significativamente.

CLOREXIDINE MOUTHWASH EFFECTIVENESS DURING ORTHODONTIC TREATMENT ABSTRACTPurpose: To evaluate the efficiency of chlorhexidine mouthwash over the amount of bacterian plaque present in adults with orthodontic treatment appliances, living in the Bucaramanga metropolitan area, patients that attend the Santo Tomas University dental clinics, during the second semester of 2007. Materials and Methods: A controlled clinical essay was performed in 60 adults with orthodontic appliances. It was established the OPI plaque index (Ortho-Plaque index) and the gingival index (GI index). The experimental group received the basic maintenance therapy, chlorhexidine digluconate at 0.2% to be used as a 10 ml non dilute mouthwash, twice (2) a day for 15 days. Results: The patients exposed to the intervention had 2.2 times probability (1.6 versus 3.3) of their IC to get the OPI index whose values reflect a good oral hygiene. Conclusions:The patients with orthodontic appliances who used chlorhexidine digluconate (0.2%), for fifteen days long had a significant reduction of bacterian plaque.
