What Kind of Orthodontic Treatment can Effect the Lactobacilli and S. Mutans Level?

Abstract

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 level in the same sample. These counts were evaluated at 5 stages: before orthodontic treatment, 4 weeks after using of removable appliances, at least 2 weeks after bonding of the brackets, 1 week after application of mouth varnish, and at the end of the orthodontic treatment.Wilcoxon signed ranks test were used to statistical determination. This study shows that orthodontic removable appliances treatment doesn't affect the lactobacilli levels significantly (P>0.05) whereas the level of the S.mutans increased significantly (P<0.05). Besides of that the level of the lactobacilli and S. Mutans didn't change significantly during fixed orthodontic treatment in this oral hygen condition as we advised (P>0.05). In addition, we found that when patients use mouth varnish during fixed orthodontic treatment these microorganism levels reduced significantly (P<0.05).

An In Vivo Evaluation of Some Denti-frices in Reducing Salivary Level of Mutans Streptococci and Lactobacillus

“…CHX is the most successful antibacte-rial therapy against supragingival and subgingival bacterial communities; daily use of this agent for two weeks can markedly reduce the cariogenic bacteria in mouth and prevent its recolonization for 3-6 months, so it may be employed as adjunct in patients with high caries activity and high count of MS. (2,7) The most common effective agents recommended by WHO, ADA and FDI are fluoride and triclosan, and regular evaluation of the efficacy of fluoridated toothpastes by the private laboratory has been recommended by WHO. (12) Various fluoride forms such as amine fluoride, sodium fluoride, and sodium monofluorophosphate have been used in toothpaste formulations.…”

“…cavitations and their presence increases the risk of decalcification, hence, their count is important in making up the "Risk Profile" of patient. (6,7) The strategies of cariogenic biofilm management include plaque elimination by home care; reduction of fermentable carbohydrate and introduction of fluoride. The practice of tooth brushing twice daily (in addition to flossing) is the standard routine suggested by the American Dental Association (ADA) to effectively preserve good oral health.…”

The Effect of Miswak and Toothbrush on Saliva Total Bacterial Count and Cariogenic Bacteria

“…(3) S. mutans has been strongly associated with the initiation of caries, while lactobacilli have been mainly connected with the further development of caries lesion. (4) The methods available for maintenance of oral health are mainly mechanical and chemical. Toothbrushes and dentrifices are widely used for cleaning teeth.…”
