Background: Oral microbiota has been at the center of cultural attention in recent years. In daily clinical practice, orthodontic appliances may be associated with an increased cariogenic risk and a worsening of preexisting periodontal diseases.Objective: The purpose of this review is to investigate the available evidence regarding the association between orthodontic appliances and changes in the quality and quantity of the oral microbiota.Design: The research included every article published up to October 2017 featuring the keywords ‘Orthodontic appliance* AND (microbiological colonization OR periodontal pathogen* OR Streptococcus mutans OR Lactobacillus spp. OR Candida OR Tannerella forsythia OR Treponema denticola OR Fusobacterium nucleatum OR Aggregatibacter actinomycetemcomitans OR Prevotella intermedia OR Prevotella nigrescens OR Porphyromonas gingivalis)’ and was conducted in the major medical databases. The methodological quality of selected papers was scored using the ‘Swedish Council on Technology Assessment in Health Care Criteria for Grading Assessed Studies’ (SBU) method.Results: Orthodontic appliances influence the oral microbiota with an increase in the counts of S. mutans and Lactobacillus spp. and in the percentage of potentially pathogenic gram-negative bacteria.Conclusions: There is moderate/high evidence regarding the association between orthodontic appliances and changes in the oral microbiota.PROSPERO registration number CRD42018091589.

Objective: The objective of this study was to develop an antibacterial flowable composite containing silver nanoparticle (AgNP) for the prevention ofperiodontal disease in fixed retainers.Methods: About 1% AgNP was incorporated into a commercial composite (tetric flow). The experimental and control products were used to bondfixed retainers to 28 extracted mandibular first premolars. The samples were randomly divided into four groups (n=7): Premolar bonded withfiber-reinforced composites and tetric flow (F1); premolar bonded with fiber-reinforced composites and AgNP-enhanced tetric flow (F2); premolarbonded with multistranded wires (MW) and tetric flow (M1); and premolar bonded with MW and AgNP-enhanced tetric flow (M2). Each sample wassubmerged in a test tube containing bacterial Treponema denticola solution and was incubated for 24 h and 37°temperature. The bacterial colony ineach group was counted and analyzed.Results: This study showed that there was significant difference of T. denticola colony count between groups with and without AgNP-enhancedcomposites in both types of retainers.Conclusion: AgNP-enhanced flowable composites reduce the bacteria T. denticola colony count and possibly inhibit periodontal disease.

“…Acrylic structure of them may influence the proliferation of microorganisms when it acts as a food deposit. Depending on its smoothness and size, it may provide plaque accumulation that leads to enamel decalcification [9,12,14]. Addy et al [15] showed that palatal plaque scores were significantly higher in wearers of removable appliances compared with a control group without orthodontic treatment.…”

The Relationship between Orthodontic Treatment and Dental Caries

Dental Caries - Diagnosis, Prevention and Management

Orthodontic treatment is the main treatment procedure to achieve a well-aligned dental arch and an esthetic smile. For this purpose, various types of removable or fixed orthodontic appliances are designed. However, each has their specific disadvantages. The most important one is that orthodontic appliances especially the brackets and the ligation mode create new retention areas in addition to blocking plaque-removing shear forces arising from fluid flow and masticatory loads with a resultant undesired effect of accumulation of dental plaque. Increased amount of dental plaque containing cariogenic bacteria is the main etiologic factor in decalcification of enamel during orthodontic treatment. This demineralization of the tooth surfaces results in appearance of white spots or even caries. However, in the literature, there are conflicting results in the relationship between orthodontic treatment and development of dental caries. Many preventive methods such as topical fluoride application, using bonding materials releasing fluoride, using mouth rinse with sodium fluoride, applying chlorhexidine, and so on were defined. The general comment of the authors is that supplying an adequate oral hygiene has the main role in prevention of demineralization-caries during orthodontic treatment. In the light of the previous studies' results, it can be concluded that professional application like a varnish can be provided for patients who have high caries incidence.
