Molar bands Vs bonds: Does bonding cements have role in microbial colonization
Journal Title: Al Ameen Journal of Medical Sciences - Year 2017, Vol 10, Issue 1
Abstract
Introduction: Dental plaque is organized in a biofilm complex that provides protection and nutrients for periodontopathic and cariogenic bacteria. Several factors can affect microbial colonization, including restorations, orthodontic brackets and bands. Aims and Objectives: The aim of this study was to investigate changes in subgingival cariogenic microbiota before and one month after the placement of orthodontic bands and bondable molar tubes using four different bonding materials. Materials and Methods: Thirty patients undergoing orthodontic treatment of age group between 12 to 25 years, were randomly selected from post graduate clinic. All first molars were banded or bonded randomly quadrant wise, using four different materials (fluoride releasing and non-fluoride releasing adhesives, chemically cured and light cured GIC). Subgingival microbial samples were taken from mesio-proximal site of the selected teeth before and one month after the placement of bands and bondable molar tubes. The samples were then inoculated on selective culture media to evaluate for Streptococcus mutans and Lactobacilli. Colonies of Streptococcus mutans and Lactobacilli were counted under digital colony counter. Results: Increased colonization of Streptococcus mutans and Lactobacilli were seen around molar bands as compared to bonding on molars, irrespective of the material being used for banding and bonding (P < 0.05). Conclusions: Bacterial colonization around molar bands was significantly higher compared to molar bonding, irrespective of the material being used for banding and bonding. Hence, molar bonding may be a better option as against molar banding to reduce the risk of caries and gingival diseases around the orthodontic appliances. Use of fluoride releasing and non-fluoride releasing adhesives, chemically cured and light cured GIC does not make any difference in the bacterial colonization.
